EPA Repeals The Legal Basis For Regulating Greenhouse...

Science Friday ·

2026/02/26

On February 12, the Environmental Protection Agency dealt a major blow to the government’s power to fight climate change by rescinding a key piece of research called the endangerment finding. The finding, issued in 2009, basically says: Greenhouse gas emissions endanger public health and welfare—and because they’re harmful, they must be regulated. It's the legal basis for the federal government’s regulation of greenhouse gases under the Clean Air Act. So what does it mean that this finding has been

How One Gene Affects Alzheimer’s Risk

2026/02/25

An estimated 500,000 people are diagnosed with Alzheimer’s disease in the United States each year, but the causes and mechanisms of the condition remain a neurological mystery. A recent study looked at the role of variants in a gene called APOE in Alzheimer’s, and found that while it’s not a simple determinant of developing the disease, that one gene seems to play a significant role in promoting disease risk. Researchers hope work like this could point to new areas to study and even potential

Autism Rates Appear To Be Even Across Sexes....

2026/02/21

There’s a long-held idea that autism is more prevalent in boys than girls—the CDC says it’s three times as common. But a growing body of research suggests the reality is more complicated. In a new study, researchers tracked autism diagnoses in millions of Swedish people born from 1985 to 2022. They found that the prevalence of autism is actually pretty even across the sexes, but people with “female” stamped on their birth certificate are often diagnosed later in life.

Wandering through a museum, you can get a glimpse of what life in ancient societies looked like. But what did it smell like? And is it even possible to get a whiff of, say, a freshly embalmed mummy, or a 5,000-year-old Saudi Arabian incense burner? That’s exactly what some chemists and olfactory designers are trying to do.Producer Kathleen Davis talks with archeo-chemist Barbara Huber and perfumer Carole Calvez about how they scientifically recreated the scent of ancient Egyptian mummies and brought

The Relativistic Heavy Ion Collider (RHIC), the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set of instruments based at New York’s Brookhaven National Laboratory, and was designed to accelerate gold ions to near-light speed before collision. It was the second most powerful accelerator on the planet, second only to CERN’s Large Hadron Collider. Since RHIC began running in 2000, scientists have used it to study

As ICE cracks down in Minneapolis and across the country, reporters and privacy advocates have drawn attention to how the agency is using technology: scanning people’s faces without consent, using private health records to make arrests, tracking people’s location in real time with phone data.So how does all this work? How does the United States’ data ecosystem make it possible for not just ICE, but any number of government agencies and businesses to buy our private data? And what actually happens
