How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss.
Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

FDA Approves Lecanemab, a New Alzheimer ’s Drug
On Jan. 6, the U.S. Food and Drug Administration (FDA) approved a new drug to treat Alzheimer’s disease in its early stages.
Lecanemab, which will be available under the name Leqembi, can slow the cognitive decline associated with Alzheimer’s disease by 27%, according to data submitted to the FDA by the drug’s developers, Eisai and Biogen. It’s only the second medication to show any improvement in neurodegeneration, a key criterion in the FDA’s consideration for approval.
“For a long time, this is what we have been looking for,” says Dr. Sam Gandy, professor of neurology and psychi...

FDA Experts Vote to Make All COVID-19 Vaccines and Boosters Bivalent
In a unanimous decision, all 21 voting members of the U.S. Food and Drug Administration’s (FDA) vaccine committee recommended that the U.S. start using the same COVID-19 virus strain in all of the COVID-19 vaccines, including primary and booster doses.
That means the bivalent booster dose, which targets both the original SARS-CoV-2 strain and the Omicron BA.4/5 strains, would soon become the only type used for all primary shots and boosters.
The decision reflects a turning point in the pandemic. Until now, vaccine makers have tried to keep up with constantly evolving variants, but they’ve always been a few step...

A Sugar Replacement May Be Linked to Heart Attacks and Strokes. Don ’ t Throw Out Your Stash Yet
Sugar replacements are everywhere in foods and beverages. But despite their ubiquity, the scientific verdict on whether or not they pose health risks ping pongs back and forth. Every so often, though, a study is published with a conclusion so shocking that it forces people to reassess their pantries. A Feb. 27 study published in the journal Nature Medicine now seems to have dealt such a blow to the sweetener erythritol, with data that suggest a connection between the ingredient and cardiovascular events such as clotting, stroke, and heart attacks.

Here ’s an Alternative to Statins for Lowering Cholesterol
Statins have revolutionized heart disease by lowering cholesterol effectively—by up to 50% or more. But anywhere from 7% to 29% of people who take them may be more susceptible to its side effects, which include weakening of muscles and pain, and decide they can’t tolerate them. In a recent study published in JAMA Network Open, for example, researchers at Brigham and Women’s Hospital reported that more than 20% of patients seen at the hospital from 2000 to 2018 who were recommended to take statins refused to take them, and those who refused took three times as long to lower their LDL cholesterol to target ...

What to Know About High Triglycerides
Discussions about heart health often center around blood pressure and cholesterol, with factors like poor sleep, smoking, family history of heart disease, and chronic stress thrown in. However, there’s one variable that doesn’t get covered as often, even though it can be an important indicator of cardiovascular risk: triglycerides.
“We don’t really talk about triglycerides very much, especially compared to cholesterol, but they’re actually an essential part of understanding heart health,” says Dr. Adriana Quinones-Camacho, a cardiologist at NYU Langone Health in New York. “For some...

Scientists Are Just Beginning to Understand COVID-19 ’ s Effect On the Brain
Early in the COVID-19 pandemic, doctors started to notice something striking. For what was originally described as a respiratory virus, SARS-CoV-2 seemed to have a strong effect on the brain, causing everything from loss of taste and smell and brain fog to, in serious cases, stroke.
NYU Langone Health, a New York city research hospital, started collating those anecdotes in hopes of better understanding how the virus affects the brain and nervous system. Years later, the project has morphed from focusing solely on acute symptoms to also tracking the long-term neurologic issues that some people with Long COVID experience, sa...

I Don’t Love Lucy: The Bad Science in the Sci-Fi Thriller
Now there are three Lucys I have to keep straight: The 3.2 million year old Australopithecus unearthed in Ethiopia in 1974; the eponymous star of the inexplicably celebrated 1950s sitcom I Love Lucy; and, most recently, the lead character—played by Scarlett Johansson—of the new sci-fi thriller straightforwardly titled Lucy. Going by intellectual heft alone, I’ll pick the millions-year-old bones.

Leading Health Experts Call For Fossil Fuel Divestment to Avert Climate Change
More than 50 of the world’s leading doctors and health researchers called on charities to divest from fossil fuel companies in an open letter Thursday. The letter, published in the Guardian, argues that climate change poses a dire risk to public health and that fossil fuel companies are unlikely to take action to reduce carbon emissions without prodding.
“Divestment rests on the premise that it is wrong to profit from an industry whose core business threatens human and planetary health,” the health experts wrote. The case for divestment brings “to mind one of the foundations of medical ethics—...

How Air Pollution Contributes to Millions of Early Deaths
Outdoor air pollution leads to more than 3 million premature deaths each year, and more than two thirds of them occur in China and India, according to new research. The authors estimate that without government intervention, the total number of deaths could double by 2050.
The study, published in the journal Nature, identifies particulate matter as the prime pollutant leading to premature mortality. Particulate matter, a substance formed as a combination of different materials released into the air, is thought to be harmful to human health once it exceeds 2.5 micrometers in diameter. Researchers also identified ozone as a c...

How a Paralyzed Man Walked Again
Adam Fritz was just another 21-year-old kid back in 2008—about to enter his senior year of college, cruising home from work on his motorcycle near Diamond Bar, California—when his life changed forever: A table from a truck in front of him slipped off and struck him, flinging him off his motorcycle onto the freeway.
“It’s what I called my ‘oh shit’ moment,” he told TIME. “I tried to sit up and get up on my feet. I remember the firefighters telling me not to move. Everything just hurt.”
Two days later, Fritz was told he had a spinal cord injury—and that he’d n...

The Oldest Fossils Ever Found Were Discovered in Greenland
Scientists have found the oldest physical evidence for life on earth in the fossils of Greenland rocks that are 3.7 billion years old.
The newly discovered fossils are 220 million years older than any previously unearthed fossil evidence, researchers wrote in the journal Nature. The fossils in the rocks are stromatolites, layered formations produced by microbial communities, the researchers wrote.
The discovery indicates that life on other planets was possible at the time.
“If we have got life at 3,700 million years on Earth, did it exist on other planets—because Mars, for example, 3,700 million years ago was w...

Extreme Heat Waves Will Change How We Live. We ’re Not Ready
Extreme heat struck across the Southwest U.S. this week, sending temperatures in Phoenix soaring to near 120°F and grounding airplanes that were unable to operate in such warm weather.
Heat waves are nothing new, but they have increased in frequency and severity in recent decades as a result of climate change. And each extreme heat event reveals another way our society simply isn’t built for such high temperatures, from our transport systems to the agriculture industry.
“We’ve built entire infrastructures with particular temperatures in mind,” says Matthew T. Huber, an associate professor of geo...
