Scientists Drilled So Deep Into the Center of the Earth, They Knocked on the Mantle’s Door

  • To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth.
  • In May of 2023, scientists drilled the deepest core yet and recovered serpentinized peridotite that forms when saltwater interacts with mantle rock.
  • Although this is the deepest into the mantle scientists have ever drilled, the mission didn’t uncover pristine mantle that lies beyond the Mohorovičić discontinuity, or Moho, boundary.

If you want to understand the geology of our home planet, studying the mantle is a great place to start. Separating the planet’s rocky crust and the molten outer core, the mantle makes up 70 percent of the Earth’s mass and 84 percent of its volume. But despite its outsized influence on the planet’s geologic processes, scientists have never directly sampled rocks from this immensely important geologic layer.

And that’s understandable, especially when you consider that the crust is roughly 9 to 12 miles thick on average. Luckily, that average contains outliers—areas of the world where the crust is actually incredibly thin and faulting exposes the mantle through cracks. One such area is the Mid-Atlantic Ridge, specifically near an underwater mountain called the Atlantis Massif.



On the south side of this massif is an area known as the Lost City—a hydrothermal field whose vent fluids are highly alkaline and rich in hydrogen, methane, and other carbon compounds. This makes the area a particularly compelling candidate for explaining how early life evolved on Earth. Additionally, it contains mantle rock that interacts with seawater in a process known as “serpentinization,” which alters the rock’s structure and gives it a green, marble-like appearance.

It was here, 800 meters south of this field, in May of 2023 that members of the International Ocean Discovery Program (IODP)—aboard the JOIDES Resolution, a 470-foot-long research vessel rented by the U.S. National Science Foundation—extracted a 1,268-meter core containing abyssal peridotites, which are the primary rocks that make up the Earth’s upper mantle. The results of the study were published last week in the journal Science.

Although this makes this particular drill core the deepest sample of the mantle yet, going that deep into the rock wasn’t the goal of this record-breaking expedition.

“We had only planned to drill for 200 meters, because that was the deepest people had ever managed to drill in mantle rock,” Johan Lissenberg, a petrologist at Cardiff University and co-author of the study, told Nature. He said that the drilling was so easy that they progressed three times faster than usual. The team eventually drilled a staggering 1,268 meters, and only stopped due to the mission’s limited operations window.



Andrew McCaig—study co-author and University of Leeds scientist—said in an article from The Conversation that, according to a preliminary analysis of the rock, the core’s composition contains a variety of peridotite called harzburgite that forms via partial melting of mantle rock. It also contained rocks known as gabbros, which are coarse-grained igneous rocks. Both of these rocks then chemically reacted with seawater, changing their composition.

While this core represents an incredibly opportunity to learn more about the Earth’s mantle, as well as give an in-depth look at the geologic substrate upon which the Lost City rests, the mission didn’t quite complete the “grand challenge” of crossing the Mohorovičić discontinuity. Otherwise known as the Moho, the Mohorovičić discontinuity is recognized as the true boundary between the crust and pristine mantle.

Future missions could continue exploring this site near the Atlantis Massif, but sadly, those missions won’t include JOIDES Resolution—the NSF declined to fund more core drilling past 2024. Just as scientists are finally knocking on the door to the Earth’s most ubiquitous geologic layer, the future of these kinds of drilling missions is now uncertain.

11 Top COVID Symptoms People Are Experiencing During the Summer Surge

11 Top COVID Symptoms People Are Experiencing During the Summer Surge

Irina Gonzalez – August 13, 2024

  • There are several COVID variants right now which have the same “set of mutations,” and are being referred to as FLiRT. Another strain, LB.1, is also on the rise.
  • KP.3.1.1 — which comes from the JN.1 strain — is now the most dominant variant, accounting for an estimated 27.8% of cases.
  • The symptoms are similar to other COVID strains. Being sick and experiencing a chronic cough, elevated fever, sore throat or a runny nose should prompt you to get a COVID-19 test to ensure you are not contagious.

If it seems like more people around you have gotten COVID in the last couple of months, that’s probably true. Right now, cases are on the rise and the COVID-19 FLiRT variants are dominating.

According to the most recent estimates from the Centers for Disease Control and Prevention (CDC) released on August 3rd, 27.8% of cases are the KP.3.1.1 strain and 20.1% of current infections are KP.3. Both of these variants stem from the FLiRT family of the coronavirus. Another variant that is not a descendant of FLiRT, named LB.1, makes up an estimated 16% of COVID-19 cases at the moment.

“The FLiRT variant appeared in March,” says Tammy Lundstrom, M.D., J.D., the senior vice president at Trinity Health who led their COVID-19 response. “Throughout the COVID-19 era, new strains have continued to arise. Like other strains, it appears highly transmissible, but it does not appear more virulent at this point.”

While it’s great that COVID-19 cases don’t seem to be as dangerous as they used to be, it still causes unpleasant symptoms which can be severe for people with certain risk factors. Unfortunately, just 22.5% of American adults had received the most recent COVID-19 vaccine as of May 11, 2024 (when the latest data was released). Could this be contributing to the summer surge we’re experiencing? We turned to experts to learn more about the newest variants, important COVID-19 symptoms to be aware of and how to protect yourself and your loved ones.

What are the FLiRT and LB.1 variants?

As fun as the name sounds, FLiRT is not the official designation for the dominant COVID-19 variant. That is actually a cheeky nickname for a whole family of different variants (any that start with KP). “The FLiRT variants came to the forefront at the end of April,” says Nikhil K. Bhayani, M.D., FIDSA, an infectious disease specialist and assistant professor at the Burnett School of Medicine at Texas Christian University.

KP.2, KP.2.3, KP.3 and KP.3.1.1 are official names of the FLiRT variants that are circulating right now. While FLiRT took over JN.1 as the dominant variant, it’s actually a descendant of JN.1. Essentially, the “parent” variant (JN.1) was unseated by several “child” variants. Various variations of JN.1 are still swirling in some capacity, but they make up a smaller percentage of COVID-19 cases. LB.1, another variant that has been circulating this summer, is not a member of the FLiRT family, but another descendant of JN.1.

Is there a summer surge?

Yes, the wastewater viral activity for COVID-19 — how the CDC tracks trends in infectious disease circulating in a community — is currently listed as “very high,” according to the most recent CDC data. However, a summer surge is not unique to FLiRT.

“Throughout the COVID-19 era, we have seen a rise in infections during summer,” says Dr. Lundstrom. Two reasons for this, according to the CDC, are that people tend to do more traveling during the summer and also congregate indoors with air conditioners on when it’s very hot outside.

What are the symptoms?

The good news is that the FLiRT and LB.1 strains of the coronavirus don’t seem to spark any surprise symptoms. “The symptoms are similar to other COVID-19 strains,” says Dr. Lundstrom. The CDC updated its list of possible symptoms on June 25th, and those include:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Sore throat
  • Congestion or runny nose
  • New loss of taste or smell
  • Fatigue
  • Muscle or body aches
  • Headache
  • Nausea or vomiting
  • Diarrhea

“Like similar recent strains, the incidence of loss of taste and smell are not prominent,” adds Lundstrom.

How long do symptoms last?

It really depends on the person. Typically, people with mild cases will experience symptoms for 5-10 days, however, many may start to feel better sooner than that. According to the CDC, most people with long COVID will start to feel better after three months, although it can last years. It’s best to speak to your doctor if any of your symptoms are lingering.

Is there a new vaccine?

Our experts said that vaccines still provide good protection against COVID-19, “especially against severe illness and hospitalization,” says Dr. Lundstrom. However, a study published in April found that KP.2 is proving to have “the most significant resistance” to the 2023-24 COVID-19 booster, and that this “increased immune resistance ability of KP.2 partially contributes to the higher” prevalence of infections “than previous variants, including JN.1.”

At the end of June, the CDC recommended that everyone ages 6 months and older receive the updated 2024-25 COVID-19 vaccine, which was tweaked based on the most dominant variants circulating this year. The most updated COVID-19 vaccine is expected to be rolled out this fall. “The World Health Organization is recommending the upcoming COVID booster to be based on the predominant lineage for the year,” adds Dr. Bhayani.

However, the CDC and our experts still recommend the current vaccine to protect yourself before the 2024-25 booster is made available in the fall. “Adults over the age of 65 should get the last COVID-19 vaccine available,” says Bhayani. Dr. Lundstrom suggests that older adults “should be vaccinated four months after their last vaccination” and those with compromised immune systems “should get vaccinated two months after their last dose.”

How to protect yourself

In March, the CDC updated the Respiratory Virus Guidance as COVID-19 cases have decreased over time. “It is still an important health threat, but it is no longer the emergency that it once was, and its health impacts increasingly resemble those of other respiratory viral illnesses, including flu and RSV,” the new guidance states.

“The same precautions will help protect against the spread of most respiratory viruses: wash hands frequently, cover your mouth and nose when sneezing/coughing, stay up to date with vaccinations and stay home when ill to prevent spreading infection to others,” suggests Dr. Lundstrom. However, Dr. Bhayani reminds us that the elderly, individuals with compromised immune systems and kids “should take extra precautions, such as avoiding large crowds and wear masks if COVID-19 cases are on the rise locally.”

If you do get sick, the CDC still recommends staying at home until your symptoms are improving overall, and you have not had a fever (and are not using fever-reducing medication). Afterward, you can resume normal activities and “use added prevention strategies over the next five days.”

The Trump Campaign Just Tweeted Something Really Racist

The Trump Campaign Just Tweeted Something Really Racist

Nathalie Baptiste – August 13, 2024

On Tuesday, an official social media account of Donald Trump’s 2024 campaign posted a racist meme implying that if Vice President Kamala Harris wins the presidency in November, nice suburban neighborhoods will be overrun with hordes of Black people and immigrants.

“Import the third world. Become the third world,” read the post on X, the former Twitter.

Side-by-side images ― captioned “Your Neighborhood Under Trump” and “Your Neighborhood Under Kamala,” respectively ― show a tranquil residential street and a 2023 Getty photo of recent migrants to the U.S. sitting outside New York’s Roosevelt Hotel in hopes of securing temporary housing. (The Roosevelt now serves as an intake center for homeless migrants, and has been described as a “new Ellis Island.”) Most of the migrants in the photo are people of color.

Even as Harris and the Democrats shift to the right on border security and immigration issues, the Trump campaign has doubled down on racial animus and anti-immigrant sentiment.

In a conversation with X owner Elon Musk on the platform Monday night, Trump repeatedly vilified immigrants, bringing up cases of alleged murders by undocumented migrants. “These are rough people,” Trump told Musk. “These are criminals that make our criminals look like nice people. And it’s horrible what they’re doing.”

Trump has, once again, made building a wall on the U.S.-Mexico border a campaign priority, and has promised that his administration will deport every undocumented immigrant living in the U.S. At the Republican National Convention in July, attendees cheered and waved signs reading “Mass Deportations Now!”

In the three weeks since President Joe Biden announced he wouldn’t seek a second term, reports have suggested that Trump is flailing for ways to counter the swell of enthusiasm for Harris, now the Democratic nominee.

Racism is a go-to approach for Trump, as evidenced by his quest over a decade ago to “prove” that then-President Barack Obama was not born in the U.S. Some of his advisers have told the media in recent weeks of their plans to rerun the “Willie Horton” playbook, referring to an infamous ad from 1988 that supporters of Republican George H.W. Bush produced for his presidential campaign against Democrat Michael Dukakis. (Trump’s current pollster and adviser Tony Fabrizio had a hand in that advertisement.)

According to The New York Times, GOP donors and Trump’s own advisers have been pleading with him to attack Harris’ policies and stay on message, instead of questioning whether she is actually Black, as he has repeatedly done in the past two weeks. The fear among conservatives is that blatant racism will drive voters away in November.

But it seems that even when attacking Harris’ immigration policies, the Trump campaign just can’t help itself.

This is now California’s worst summer COVID wave in years. Here’s why

This is now California’s worst summer COVID wave in years. Here’s why

California’s strongest summer COVID wave in years is still surging, and an unusual midsummer mutation may be partly to blame.

There are a number of possible culprits behind the worst summer infection spike since 2022, experts say. A series of punishing heat waves and smoke from devastating wildfires have kept many Californians indoors, where the disease can more easily spread. Most adults are also well removed from their last brush with the coronavirus, or their last vaccine dose — meaning they’re more vulnerable to infection.

But changes in the virus have also widened the scope of the surge.

Of particular concern is the rise of a hyperinfectious subvariant known as KP.3.1.1, which is so contagious that even people who have eluded infection throughout the pandemic are getting sick.

“COVID is extraordinarily common now,” said Dr. Elizabeth Hudson, regional chief of infectious diseases for Kaiser Permanente Southern California’s 16-hospital healthcare system.

COVID hospitalizations are ticking up, but remain lower than the peaks for the last two summers, probably thanks to some residual immunity and the widespread availability of anti-COVID drugs such as Paxlovid.

The World Health Organization has warned of COVID infections rising around the world, and expressed concern that more severe variants could emerge.

“In recent months, regardless of the season, many countries have experienced surges of COVID-19, including at the Olympics,” said Dr. Maria Van Kerkhove, the WHO’s technical lead on COVID.

Among those caught up was 27-year-old American sprinter Noah Lyles, who after winning the gold in the men’s 100-meter finals, came up short Thursday during the 200-meter finals, taking the bronze. Lyles collapsed after the race, fighting shortness of breath and chest pain, and was later taken away in a wheelchair.

“It definitely affected my performance,” he said of the illness, estimating that he felt “like 90% to 95%” of full strength.

The rate at which reported coronavirus tests are coming back positive has been rising for weeks — to above 10% globally and more than 20% in Europe. In California, the coronavirus positive test rate was 14.3% for the week that ended Aug. 5 — blowing past the peaks from last summer and winter — and up from 10% a month ago.

There were already indications in May that the typical U.S. midyear wave was off to an early start as a pair of new coronavirus subvariants — KP.2 and KP.1.1, collectively nicknamed FLiRT — started to make a splash, displacing the winter’s dominant strain, JN.1.

But by July, a descendant strain, KP.3.1.1, had clearly taken off.

“KP.3.1.1 is extremely transmissible and a little bit more immune evasive. It kind of came out of the blue during the summer,” said Dr. Peter Chin-Hong, an infectious-diseases specialist at UC San Francisco.

Read more: COVID surging in California. Is it time to bring back masks, hand sanitizer? What experts say

Cases are up at Kaiser Permanente Southern California, and “looking through the CDC data … KP.3.1.1 is really what is driving this particular surge,” Hudson said. “We are certainly much higher than we were last summer.”

Anecdotally, some infected people report being “pretty darn miserable, actually — really severe fatigue in the first two days,” Hudson said.

People may want to think their symptoms are just allergies, she said, but “it’s probably COVID. So we’re just really encouraging folks to continue to test.”

An initial negative test doesn’t necessarily mean you’re out of the woods, though. Officials recommend testing repeatedly over as many as five days after the onset of symptoms to be sure.

California has now reported four straight weeks with “very high” coronavirus levels in its wastewater, according to data released by the U.S. Centers for Disease Control and Prevention on Friday. That followed five weeks of “high” viral levels.

Last summer, California recorded only eight weeks with “high” coronavirus levels in wastewater, and never hit “very high” levels. In the summer of 2022, California spent 16 weeks with “high” or “very high” levels of coronavirus in wastewater.

“Fewer people got immunized this year compared to last year at this time,” Chin-Hong said. “That means, particularly amongst people who are older, they’re just not equipped to deal with this virus.”

There are 44 states with “high” or “very high” coronavirus levels in their wastewater, according to the CDC. Five states, and the District of Columbia, have “moderate” levels, and there were no data for North Dakota.

The CDC said coronavirus infections are “growing” or “likely growing” in 32 states, including California; are “stable or uncertain” in seven states, as well as the District of Columbia; are “likely declining” in Connecticut; and “declining” in Hawaii and Nevada. There were no estimates in eight states.

In Los Angeles County, coronavirus levels in wastewater jumped to 54% of last winter’s peak over the 10-day period ending July 27, the most recent available. A week earlier, coronavirus levels in wastewater were at 44% of last winter’s peak.

For the week ending Aug. 4, L.A. County reported an average of 479 coronavirus cases a day, double the number from five weeks earlier. Cases are an undercount, only reflecting tests done at medical facilities — not self-tests conducted at home.

In Santa Clara County, the most populous in the San Francisco Bay Area, coronavirus levels were high in all sewersheds, including San Jose and Palo Alto.

Hospitalizations and emergency room visits related to the coronavirus are also rising. Over the week ending Aug. 3, there were an average of 403 coronavirus-positive people in hospitals in L.A. County per day. That’s double the number from five weeks earlier, but still about 70% of last summer’s peak and one-third the height seen in summer 2022.

For the week ending Aug. 4, 4% of emergency room encounters in L.A. County were classified as related to the coronavirus — more than double the figure from seven weeks earlier. The peak from last summer was 5.1%.

“We’ve had a few people who have become very ill from COVID. Those are people who tend to be pretty severely immunocompromised,” Hudson said.

UC San Francisco has also seen a rise in the number of coronavirus-infected hospitalized patients. As of Friday, there were 28, up from fewer than 20 a week earlier, Chin-Hong said.

In the Bay Area, three counties have urged more people to consider masking in indoor public settings because of the COVID surge. Contra Costa County’s public health department “recommends masking in crowded indoor settings, particularly for those at high risk of serious illness if infected,” the agency said Tuesday, following similar pleas from San Francisco and Marin County health officials.

Compared with advice such as washing hands and staying away from sick people, suggesting wearing a mask can provoke strong opposition from some.

“The moment people see this, like in their mind, it sets off this chain reaction of, like, all the negative things of the pandemic, having to have society shut down and social isolation,” said Dr. Abraar Karan, an infectious-disease doctor and researcher at Stanford University.

But masks do help reduce the risk of infection, and people don’t have to wear them all the time to benefit. Karan says he socializes and eats at indoor restaurants. But he’ll decide to mask in other situations, like “when I’m traveling,” and, obviously, at work.

Read more: Long COVID risk has decreased but remains significant, study finds

Doctors say that wearing a mask is one of many tools people can use to reduce their risk, and can be especially helpful when in crowded indoor settings.

Karan said he’s seen more coronavirus-positive patients while working shifts in urgent care, and he suggested that more healthcare providers take the time to order tests. He said he worries that when people come in with relatively mild symptoms, they may be sent home without testing.

But that could miss potential COVID diagnosis, which could allow a patient to get a prescription for an antiviral drug like Paxlovid.

Without testing, “you run the risk of taking shortcuts and not prescribing people meds that they actually should technically be getting,” Karan said.

Doctors Say Walking This Much Per Day Could Decrease Disease-Causing Inflammation

Olivia Luppino, Laura Purdy, MD – August 12, 2024

doctors share how to reduce inflammation in the body by reducing stress, getting more sleep, and healthy diet
7 Science-Backed Ways To Reduce InflammationCathrine Wessel


“Hearst Magazines and Yahoo may earn commission or revenue on some items through these links.”

If you’ve scrolled through TikTok lately, you’ve probably seen tons of videos about how to reduce inflammation in your body. The topic is going viral for good reason, too—inflammation is the precursor of most modern chronic diseases, says Maya Feller, RD, the founder and lead dietitian at Maya Feller Nutrition, so it’s no wonder people are concerned with it.

Inflammation isn’t always a bad thing, so you don’t want to (and can’t) rid your body of it entirely. It’s actually a normal part of your body’s immune system.

“Inflammation is a completely natural process, and it’s a response usually to either injury or infection,” says Valerie Gustave, MD, a gastroenterologist at Lenox Hill Hospital and NYU Langone Medical Center. For example, acute inflammation might occur when you get a cut or twist your ankle to help your body heal.

But when inflammation is chronic, it can be an issue. Rheumatoid arthritislupusCrohn’s disease and irritable bowel syndrome are all inflammatory conditions, and symptoms like fatigue, low energy, recurrent rashes, joint pain, and unexplained stomachaches can also be caused by persistent inflammation, says Micaela Bayard, MD, a rheumatologist at Mount Sinai. For any of these conditions or symptoms, you should speak with a doctor to evaluate your inflammatory markers, confirm an issue, and help you determine the best path forward.

In addition to medicine, part of that path might include lifestyle changes. These expert-approved tips are the foundation of healthy living—and can possibly help prevent excess inflammation in the future.

Meet the experts: Valerie Gustave, MD, MPH, is a gastroenterologist at Lenox Hill Hospital and NYU Langone Medical Center. Micaela Bayard, MD, is a rheumatologist at Mount Sinai. Maya Feller, RD, is the lead dietitian at Maya Feller Nutrition and author of Eating from Our Roots: 80+ Healthy Home-Cooked Favorites from Cultures Around the World.

How To Reduce Inflammation

If you’re dealing with fatigue, recurrent rashes, joint pain, or any of the symptoms described above, it may help to make an appointment with your doctor to rule out any chronic conditions. And if you want to take better care of yourself in general and reduce your risk of inflammation, you can start with the basics, Dr. Gustave says. Here are seven simple, science-backed ways to reduce inflammation and boost your health overall.

Drink Less Alcohol

Cutting back on booze is one way to tamp down inflammation.

“The body recognizes alcohol as a toxin,” says Feller, so it’s no surprise that it gets a big reaction from your immune system. “The problem with alcohol is that it can very actively stimulate what we call ‘pro-inflammatory molecules’ that trigger more inflammation,” says Dr. Bayard.

And if you already have a chronic condition that causes your body to be at an “elevated level of inflammation,” drinking alcohol can make things worse, she says.

Drinking alcohol contributes to systemic inflammation (the kind that causes chronic diseases) by messing with your gut’s microbiome, liver function, and even brain. And all those symptoms you get during a hangover? They’re an inflammatory response, too—and their severity might reflect systemic inflammation caused by drinking, according to a 2024 study in Alcohol: Clinical and Experimental Research. The more intense your hangovers are, the more inflammation you’re probably experiencing—and this drinking-inflammation cycle may put you at significantly greater risk of long-term health problems like significant liver damage and tissue damage in your gut, the study found.

If you’re looking to make a change, you don’t have to go cold turkey.

“Reduce in a way that is realistic for you,” Feller says. The less alcohol, the better, but “moderate drinking” for a woman is described as one drink or less per day, per the Centers for Disease Control and Prevention (CDC).

Cut Out Tobacco

Consuming tobacco in any form (cigarettesvapes, and hookah) harms your gut and lungs, and when it comes to inflammation, smoking can put you at risk for developing chronic health issues. In fact, one of the most well-documented causes of rheumatoid arthritis is smoking. This is because inflammation—your body’s natural immune response—can be found wherever there’s cell or tissue damage, and smoking causes plenty of damage in your body, says Dr. Bayard. “If you’re inhaling something that can be damaging to the tissue, that’s an area where inflammation can then accumulate,” she says.

The bottom line? Stopping smoking will make a big difference on your overall health, and not just your inflammatory markers, says Dr. Gustave.

Get A Good Night’s Sleep

Getting enough quality sleep is easier said than done, but turns out it’s super important for your health and for mitigating inflammation in the body. This is because sleep is a vital part of our immune response. Sleep is restorative, and during sleep, your immune system releases messenger proteins that help healing and fight infections, Dr. Bayard says.

Inconsistent sleep may be associated with higher levels of inflammation, especially for women, according to a 2020 study in Frontiers in Neurology. Sleep disturbances like waking up in the middle of the night could trigger inflammatory responses in the body, the study found. Without deep, uninterrupted sleep, your body won’t have the time it needs to let your immune system regenerate and heal the acute inflammation in your body, says Dr. Bayard.

As for how much sleep you should get? You’ll need less as you get older, but six to seven hours is a good place to start, says Dr. Bayard.

Reduce Stress

Stress plays a role in inflammation, says Dr. Bayard. One major reason is that cortisol (a stress hormone) can cause your body to switch on genes that trigger an inflammatory response. Stress can prompt inflammation in the body and may even lead to conditions like depression, per a 2022 study in the journal BiomedicinesFinally, stress can disrupt your sleepappetite, and mindfulness, which all play a role in inflammation, Dr. Bayard says.

Get Some Physical Activity In

Exercise can decrease inflammation by releasing proteins that lower an inflammatory response and helping metabolize excess sugars in the bloodstream, says Feller.

While it doesn’t quite matter what you do—just as long as you’re active for about 30 minutes most days—if you’re concerned with inflammation, high-impact exercise might not be the way to go. That’s because exercise that is too hard on your body could cause more inflammation, says Dr. Bayard. (Everyone is different, so pick whatever gets you moving and see how it feels for you.)

If you’re not sure where to start, low-impact exercise might be just what you need to manage inflammation (without going overboard or stressing your body out). Bikingwalking with supportive shoesswimming, or hopping on the elliptical are all examples of low-impact workouts that can help you get all of exercise’s anti-inflammatory benefits.

Be Mindful Of Additives And Processed Foods

Sugar, salt, and processed foods might be hard to avoid, but they can play a role in inflammation. High levels of sugar can promote tissue damage and breakdown, leading to more inflammation, says Dr. Bayard, and eating processed foods pose a challenge to our digestion, which can promote inflammation in the gut.

“We’re learning a lot about how these chemicals that we take in impact our body,” says Dr. Bayard, but striving to eat less of them could help.

Eat The Rainbow

Finally, diet plays a role in inflammation, and WH has you covered with an anti-inflammatory food guide (think: plenty of nutritious whole foods packed with omega-3s and plant-based options). In addition to following that diet, a Mediterranean diet promotes eating limited red meat, green vegetables, and non-processed foods, all of which can be anti-inflammatory, says Dr. Bayard.

Overall, the key to reducing inflammation in your body is prioritizing variety and non-processed foods.

“If people can eat 30 different diverse plant foods over the course of the week, that’s very beneficial for gut health,” says Feller. “And we know that the gut has a big role in terms of immune health and also inflammatory conditions throughout the body.”

CDC says COVID wastewater levels are ‘very high’ in VA and NC

KaMaria Braye – August 12, 2024

PORTSMOUTH, Va. (WAVY) – The Centers for Disease Control and Prevention (CDC) reports that wastewater levels of COVID-19 are considered very high across the United States.

At least 26 states are either high or very high for COVID-19 infections. The data shows this summer’s COVID-19 levels could pass the previous two summers.

‘Very high’ COVID levels detected in 7 states

The CDC says sewage can be tested to find traces of infectious diseases in communities and that the diseases can be found even if people don’t have symptoms.

As of Aug. 12, Virginia and North Carolina’s viral activity level is very high.

With most Hampton Roads school districts returning back to school starting in mid-August, the CDC has recommendations for parents to help kids stay healthy while learning.

Are schools ready for COVID-19 as students head back to class?

More than half of U.S. states are reporting “very high” levels of COVID activity as the virus continues to spread and increase in many parts of the country, according to the latest wastewater data from the Centers for Disease Control and Prevention.

At least 27 states are reporting “very high” levels and 17 states are reporting “high” levels of wastewater viral activity.

The western region continues to see the highest levels followed by the South, Midwest and Northeast, respectively.

Current levels are nearing but remain lower than what they were in the winter months, when there tends to be increased spread of respiratory illnesses.

Wastewater data comes with limitations in how well it represents spread in a community, but it may be the best data available, experts say.

“While wastewater is not a perfect measure, it’s increasingly vital in filling the gaps left by the absence of comprehensive case reporting and hospitalization data,” said Dr. John Brownstein, an epidemiologist and chief innovation officer at Boston Children’s Hospital and an ABC News contributor.

Many national surveillance systems have diminished in scope since the national public health emergency ended, leaving authorities will limited resources to monitor how the virus is spreading.

“As traditional surveillance systems have dwindled, wastewater analysis has emerged as one of the most reliable tools we have to monitor COVID-19 activity in communities,” Brownstein added.

Other limited COVID surveillance systems such as emergency department visits and test positivity are also on the rise, according to CDC data. Deaths from the virus remain relatively flat, especially compared to previous years.

Updated COVID vaccines are set to be available this fall, according to federal health authorities. The U.S. Food and Drug Administration recommended that vaccine manufacturers formulate shots based on the KP.2 strain, an offshoot of the omicron variant that is currently estimated to make up about 6% of cases.

Genetically similar variants, known as KP.3.1.1 and KP.3, currently make up almost half of estimated cases, CDC data shows.

The CDC has already recommended that everyone over the age of 6 months get an updated COVID vaccine this season. The recommendation will take effect as soon as the vaccines are made available, pending FDA authorization.

An expected delivery date for the updated COVID vaccines has not been shared yet, but in previous years the shot was made available in late August or September. Vaccine manufacturers have told ABC News they are ready to ship doses as soon as they receive the green light from the FDA.

Potential Tropical Cyclone Five expected to become tropical storm within next few days

TAMPA, Fla. (WFLA) — The National Hurricane Center issued its first advisory for Potential Tropical Cyclone Five on Sunday as it’s likely to develop into a tropical storm within the next few days.

The system has a 90% chance of development within the next seven days and has ramped up to an 80% chance within 48 hours, the NHC said in a 5 p.m. update.

The wave, which is located about 1,530 miles east-southeast of Antigua, continues to show signs of organization.

The NHC said the system is moving toward the west-northwest at 21 mph with maximum sustained winds of 30 mph. It is expected to move across portions of the Leeward Islands on Tuesday and approach the U.S. and British Virgin Islands on Tuesday night.

“Some strengthening is forecast and the system is expected to become a tropical storm by late Monday,” the NHC said. Ernesto is the next storm name on the list.

“The good news is that it’s expected to turn to the north well to the east of the U.S. and Bahamas and may impact Bermuda later this week,” Max Defender 8 Meteorologist Eric Stone said. The system is not expected to impact Florida.

Why Japan issued its first-ever ‘megaquake advisory’ — and what that means

Why Japan issued its first-ever ‘megaquake advisory’ — and what that means

Evan Bush – August 10, 2024

'Megaquake' explained: Japan issues warning after 7.1-magnitude earthquake

The Summary
  • Japan’s meteorological agency on Thursday issued its first-ever “megaquake advisory.”
  • The warning followed a 7.1-magnitude earthquake off the country’s southern coast.
  • That raises the risk of an even larger quake on the Nankai Trough, an underwater subduction zone that scientists believe is capable of producing temblors up to magnitude 9.1.

After a 7.1-magnitude earthquake shook southern islands in Japan on Thursday, the country’s meteorological agency sent out an ominous warning: Another, larger earthquake could be coming, and the risk will be especially high over the next week. In the first “megaquake advisory” it has ever issued, the agency said that the risk of strong shaking and a tsunami are greater than usual on the Nankai Trough, a subduction zone with the potential to produce magnitude 8 or 9 temblors. Area residents, it said, should prepare.

The message was not a prediction, but a forecast of enhanced risk — and it shows how far seismologists have come in understanding the dynamics of subduction zone earthquakes.

Here’s what to know about the situation.

A dangerous subduction zone

The Nankai Trough is an underwater subduction zone where the Eurasian Plate collides with the Philippine Sea Plate, forcing the latter under the former and into the Earth’s mantle.

Subduction zone faults build stress, and a so-called megathrust earthquake takes place when a locked fault slips and releases that stress. “Megaquake” is a shortened version of the name. These zones have produced the most powerful earthquakes in Earth’s history.

The Pacific “Ring of Fire” is a collection of subduction zones. In the U.S., the Cascadia subduction zone off the West Coast runs from Vancouver Island, Canada, to Cape Mendocino, California.

The Nankai Trough fault has several segments, but if the entire margin of the fault were to slip at once, Japanese scientists believe the trough is capable of producing an earthquake of up to magnitude 9.1.

If a megaquake were to happen near Japan, the Philippine Sea Plate would lurch, perhaps as much as 30 to 100 feet, near the country’s southeast coast, producing intense shaking. The vertical displacement of the seafloor would cause a tsunami and push waves toward the coast of Japan. Those waves could reach nearly 100 feet in height, according to estimates from Japanese scientists published in 2020.

A history of big quakes

The Nankai Trough has produced large earthquakes roughly every 100 to 150 years, a study indicated last year. Japan’s Earthquake Research Committee said in January 2022 said there was a 70% to 80% chance of a megathrust earthquake in the subsequent 30 years.

Large Nankai Trough earthquakes tend to come in pairs, with the second often rupturing in the subsequent two years. The most recent examples were “twin” earthquakes on the Nankai Trough in 1944 and 1946.

The phenomenon is due to the segmented nature of the fault; when one segment slips, it can stress another.

Thursday’s magnitude-7.1 earthquake took place on or near the subduction zone, according to the United States Geological Survey.

Harold Tobin, a University of Washington professor who has studied the Nankai Trough, said the magnitude-7.1 quake took place in a segment that shakes more frequently than others. Regular earthquakes can relieve stress, so the possibility that the segment itself produces a big earthquake is less of a concern. The worry is the earthquake’s proximity to a segment that’s been building stress since the 1940s. “It’s adjacent to the western Nankai region and that’s clearly locked up. That’s the reason for alert and concern,” Tobin said.

A forecast, not a prediction

Scientists can’t predict earthquakes, but they are developing the ability to forecast times of heightened risk, particularly in areas with frequent shaking and good monitoring equipment, like Japan.

Japanese authorities are asking residents to prepare, review evacuation routes and pay attention to potential future warnings. While the risk of a large quake is higher than usual, that doesn’t mean it will happen anytime soon. Japanese government warning guidelines suggest that the chance a large earthquake follows a magnitude-7 within a week is roughly “once per a few hundred times,” according to the study last year.

The most likely outcome is that the recent shaking won’t trigger anything, even though the probability of a large earthquake is higher.

“We might wait decades before Nankai has another earthquake,” Tobin said.

A known danger

In 2011, an area of the seafloor roughly the size of Connecticut lurched all at once, producing a magnitude-9.1 earthquake — the third biggest recorded worldwide since 1900. That megathrust earthquake caused a tsunami off Japan’s eastern coast. More than 18,000 people died in the tsunami and earthquake, according to the U.S. National Oceanic and Atmospheric Administration.

The following year, the Japanese government revised its natural disaster scenarios and found that some 323,000 people could die in a worst-case scenario earthquake on the Nankai Trough, mostly from tsunami effects.

The Cascadia Subduction Zone poses a similar risk for the U.S. West Coast, though megathrust earthquakes are expected there less often — every 300 to 500 years. This fault has the capability of producing a magnitude-9.1 earthquake and tsunami waves 80 feet in height. Researchers recently mapped the fault in detail and found it was divided into four segments.

The Founders Saw This Insane Political Moment Coming 237 Years Ago

If you’re feeling wrung out from the last dizzying weeks of political news, just imagine how the word “unprecedented” must be faring, dragged from its recliner for daily — sometimes hourly — workouts. It needn’t have been.

To understand how we got here, it’s helpful to return to another sweltering summer, a summer when everything actually was without precedent. The 55 men who assembled in Philadelphia 237 years ago to hammer out an American Constitution differed on a great many things. Among the rare points on which most agreed was that the American people could not be trusted to choose a president for themselves. They were easily misled, too often “the dupes of pretend patriots.” The size of the country alone made an informed electorate impossible, given the press, the postal service and the miserable infrastructure.

Slavery (barely discussed) and the mechanics of representation (much discussed) proved vexing. But few questions so confounded the delegates to the 1787 Constitutional Convention as those pertaining to the American presidency. The Articles of Confederation, which had held the colonies together through the Revolution, had made no provision for a chief executive. How should the president be selected and how long should he serve? By what mechanism could he be removed? Should he report to the legislature? Should Congress be empowered to impeach him? What qualified as an impeachable offense?

No subject proved more divisive or elicited such a staggering array of options. It befuddled the delegates in June. They wrangled with it still in September.

King George III loomed large over the proceedings; a single executive seemed a high-risk proposition. Several Southerners favored a three-person executive, a committee that would represent each region of the fledgling Republic. From the start there was concern that rural voices would be drowned out. Some delegates worried that multiple officeholders would dilute the power of the presidency. Others feared the authority of an American president might come even to exceed that of the king. Would a president not do all in his power to retain his hold on the office? What if he committed crimes? “Will not the immense difference between being master of everything and being ignominiously tried and punished” move him to cling to the office, Patrick Henry would later ask. (He had refused to attend the convention because, he claimed, he “smelt a rat.”)

The doctrine of separation of powers asserted itself only slowly. It dogged the delegates as they argued back and forth, attempting to deliver an American presidency that was both insulated from and accountable to Congress. The initial idea was for Congress to elect the chief executive, an idea that met with early, unanimous agreement. The more it was discussed, the muddier the matter grew. Perhaps state legislatures should do the electing? One term seemed sufficient in June but wrongheaded by July. It had not yet occurred to the delegates that the president would sit at the head of a political party. In the original conception he was to transcend factions, like a British sovereign.

A presidential term, it was initially agreed, should be seven years. The convention went on to entertain options of six, 11, 12, 15 and 20 years. Early on, the delegates converged upon a single term, though some had a different definition of what one term constituted. The most ardent proponent of executive authority, Alexander Hamilton, believed a president should serve for life. “It may be said, this constitutes an elective monarchy,” he conceded. But the president best able to resist popular pressures, corruption and foreign influence was the president with life tenure. “An executive is less dangerous to the liberties of the people when in office during life, than for seven years,” argued Hamilton.

Benjamin Franklin — at 81, older than everyone in the room, in most cases by decades — demurred. Even if that executive were a man of unerring, incorruptible instincts, what would happen if he were to grow frail? A man’s life often outlasted his prime, observed Franklin, who strayed from his chair only with visible difficulty. He meandered freely from his point. He entrusted most of his speeches to a colleague.

Weeks of heated inconclusiveness followed. How to remove an unfit executive, whether to allow him a veto and the extent of his powers occupied days. So did the question of salary. At one point it was suggested that anyone elected to the presidency be in possession of a “clear unencumbered estate” of at least $100,000, an amount equivalent to roughly $3.5 million today. Franklin objected, generally opposing the idea that rights be restricted to property owners. “Some of the greatest rogues he was ever acquainted with,” he was said to have quipped, “were the richest rogues.” He strongly urged that the president be reimbursed only for his expenses.

Having spent years in London, having observed the British court at close hand, he knew that men made outlandish efforts to grasp and retain lucrative, powerful offices. He warned against a natural inclination to embrace kings. (He may or may not have known that nearly half his colleagues seemed to prefer some form of royal government.) “I am apprehensive, therefore — perhaps too apprehensive,” he warned, “that the government of these states may in future times end in a monarchy.” An awkward moment followed. In the room, after all, stood General Washington, who had served his country for eight years with honor and without profit. Franklin’s motion found a respectful second. It seems never to have returned to the table.

Some parts of that summer sound deeply familiar. There were long weeks of acrimony and about-faces, personal attacks and pouting. There were deadlocks, diatribes and tantrums. Consensus remained elusive for months and arrived grudgingly in the end. Ultimately it was James Madison who crafted the bare bones of the Electoral College, a system born of confusion and bruising exasperation. (When finally it came time for individual states to ratify the Constitution, some Pennsylvania delegates hid themselves away in their boardinghouses, from which they had to be bodily dragged.) Six days a week the delegates suffocated together for hours, practically seated atop each other in a stifling forty-by-forty-foot room. They took no daily breaks. It was not always possible to follow the debate.

In cutting a Constitution from whole cloth, the delegates met with infinitely more negative examples than appealing models. They had reviewed the republics of antiquity. They had examined the modern states of Europe. They had read their Hume, Montesquieu and Blackstone. They found no single formula that suited their purposes. They had agreed on secrecy — the room felt particularly airless as, for security, the windows were locked tight — an oath that has hampered historians ever since but did nothing to stanch the misinformation that flew from Philadelphia. Toward late July a rumor flew around New England that the delegates had resolved to invite George III’s second son to be crowned king of America.

Then, in mid-convention, came something wholly startling. During a particularly bitter June impasse, Franklin ventured to observe that five weeks’ work had yielded lamentably little. At that same Philadelphia address the Continental Congress had appealed for divine illumination. Should this new assembly do the same? The full Congress consisted of 53 Protestants, the majority of them Episcopalians. Two Catholics rounded out the ranks. Many of them were men of deep piety. If they were founding an American Christian nation when they wrote the Constitution it was not obvious: Franklin’s proposal met with a deafening silence. Hamilton gamely weighed in, to comment that an appeal to heaven would likely alarm the country. It reeked of desperation. A North Carolinian objected that Congress was without the funds to pay a cleric. Only three or four delegates, Franklin noted with what sounds like astonishment, thought prayer essential!

Much of what was said in that room suggests that the founders guessed we would sooner or later wind up injecting coconuts and couches into our political discourse. When they were not attempting to craft a viable American presidency, the delegates worried about how to protect a fledgling government from the worst instincts of its constituents. Those, too, were on full display that July, when the unprecedented collided with the immemorial.

Already once that spring a Philadelphia mob had attacked in the street an elderly German woman named Korbmacher. Long suspected of witchcraft, she was rumored to have poisoned a child with a magic charm. On July 10, a week during which the convention wrangled with the three-fifths clause, a formula that struck even its proposer as abhorrent, the widow Korbmacher was again attacked. This time her assailants armed themselves with stones and knives. She died from her injuries a week later while inside the State House the best minds in America designed — for citizens they felt might not best be trusted with their own political choices — the most enlightened government they could imagine. “Prejudices, worm-eaten prejudices, as our old companions, are hard to be parted with,” The Pennsylvania Packet opined about the attack.

The case went to court in October. It is unclear if the presiding judge handed down any convictions, though he did allow himself a comment from the bench. How had a wrinkled old crone caused such a commotion? Now if some of the luscious damsels he had noticed around town, “animated with the bloom of youth and equipped with all the grace of beauty” had been charged, the accusation would merit attention. Those women, he declared, were created to befuddle and bewitch.

The record is silent as to whether old Korbmacher was childless or owned even a single cat.
