Getting COVID-19 Can Weaken the Immune System

Even relatively easy bouts with COVID-19 can still take a toll on the immune system, according to a paper published Mar. 15 in the journal Immunity—particularly on T-cells, which provide long term and durable protection against viruses.

Mark Davis, a professor of immunology at Stanford University and director of the Stanford Institute for Immunity, Transplantation, and Infection, and his team made the discovery when studying T cell responses to SARS-CoV-2 among 72 people through the early months of 2021, as the first COVID-19 vaccines were becoming available. They used the most sensitive method available to track changes in T cell responses, relying on an engineered molecule that can detect up to five-fold more T cells targeting SARS-CoV-2 than other molecules. The …

Our Vocabulary Is Adapting to a Hotter Planet

There was no way of knowing on Aug. 8, 1975, just how many readers turned to the new paper in the journal Science by geochemist Wallace Broecker, of Columbia University’s Lamont-Doherty Earth Observatory. It was hardly possible to track clicks or likes nearly half a century ago, so Broecker simply had to hope his message got through. It was a pressing one, conveyed directly by its headline: “Climatic Change: Are We on the Brink of a Pronounced Global Warming?”

The headline marked the first time the term “global warming” is known to have appeared in print, according to NASA. Though Broecker, who died in 2019 after devoting decades to studying and writing about climate change, might have hoped for more from his ground-breaking article, there was barely a whisper f…

Russian Elite Reportedly Given Experimental COVID-19 Vaccine

(Bloomberg) — Scores of Russia’s business and political elite have been given early access to an experimental vaccine against COVID-19, according to people familiar with the effort, as the country races to be among the first to develop an inoculation.

Top executives at companies including aluminum giant United Co. Rusal, as well as billionaire tycoons and government officials began getting shots developed by the state-run Gamaleya Institute in Moscow as early as April, the people said. They declined to be identified as the information isn’t public.

The Gamaleya vaccine, financed by the state-run Russian Direct Investment Fund and backed by the Defense Ministry, last week completed a phase 1 trial involving military personnel. The institute hasn’t publ…

Study Reveals Link Between Air Pollution and Stillbirths_2

About 140 million babies were born globally last year—the equivalent of adding an entire new Russia to the world’s population. Not counted among those typically blessed events are the number of families whose pregnancies end tragically. According to the United Nations Interagency Group for Child Mortality Estimation, about 2 million pregnancies around the world end in stillbirth each year. The causes of natal death are numerous—from fetal abnormalities to labor complications to maternal hypertension to infections to placental malformation.

Now, according to a new study in Nature Communications, there is another, particularly pernicious cause that may account for up to 39.7% of stillbirths in low- and middle-income countries: air pollution, specifically in…

The Water Crisis No One In America Is Fixing

On Feb. 3, 2022, a train loaded with toxic chemicals derailed in East Palestine, Ohio, igniting a fire and forcing the controlled release and burn of vinyl chloride, a known cancer-causing compound, to avert a disastrous explosion. The environmental catastrophe killed thousands of fish in nearby streams and has triggered growing concerns over the impact on residents’ health and on the village’s surface, ground, and well water.คำพูดจาก สล็อตเว็บตรง

East Palestine joins a long list of other places in the United States facing major threats to clean water. In October 2022, a campaign called “Imagine a Day Without Water” asked Americans to stand wi…

Trump Prompted G20 Climate Statement on Paris Accord

As President Trump mulled pulling the U.S. out of the Paris Agreement on climate change earlier this year, supporters of bold policies to address global warming around the world feared that the U.S. withdrawal would hinder action on the issue.

But on Saturday, with the exception of Trump, the leaders of the world’s largest economies gathered at the G20 reaffirmed their commitment to fostering clean energy development and implementing the Paris Agreement on climate change. Instead of attracting other laggards, Trump’s decision freed the rest of the world to issue a strong Climate and Energy Action Plan for Growth Saturday that aims to address global warming — and measures aimed at appeasing Trump were mostly absent.

“In the end, the negotiations on cli…

We Used to Have a Lyme Disease Vaccine. Are We Ready to Bring One Back-

At my animal hospital in upstate New York, an epicenter of the U.S. tick epidemic, my dog Fawn lets out a whimper as the veterinarian injects her with her annual Lyme disease shot. I roll my eyes. She doesn’t know how good she has it.

The injection means that if a tick bites her (and in rural New York, a tick always does), the creepy crawly will feast on dog blood that’s been supercharged with a Lyme bacteria-killing substance, and Lyme disease won’t be transmitted to Fawn.

I wish I could be shot up with that superpower. Currently, there is no human vaccine for Lyme disease—even though more than two decades ago, people could get a safe and effective preventative shot similar to Fawn’s. Now, thanks to potent anti-vaccine pushback, all we can do i…
