Clips & Podcasts on Instagram: The American Council on Science and health was founded in 1978 by a group of scientists who had become concerned that many important public policies related to health and the environment did not have a sound scientific basis. These scientists created the organization to add reason and balance to debates about public health issues and to bring common sense views to the public.

Raindrops are tiny lightning bolts, and they’re corroding cars, study finds

The standard explanation for why rain causes corrosion is that water carries dissolved salts and acids to a surface, constant drumming of raindrops abrades whatever protective coating is on it, and oxygen does the rest. Nearly all our tools to prevent this—paints, polymer films, or oxide layers—are built around this idea. But we’ve apparently been missing something important about the rain.

New study reveals a major perk of being single

Marriage has been well-studied and has even been linked with certain mental and physical health benefits. But new research suggests that singlehood comes with its own boon.

In a series of three studies, which included two diary studies followed by an experimental one, researchers examined what they call “singlehood self-expansion potential,” or the belief that being single offers opportunities to broaden your sense of self via exposure to new experiences, perspectives and relationships in a way that has previously been associated with being in a partnership.

Sounding the Alarm about Medical Misinformation

Medical misinformation has a peculiar advantage: it can outlive the evidence that disproves it, especially when yesterday’s contrarians become today’s policymakers. In Everyone Else Is Lying to You, physician Jonathan Howard keeps the receipts, documenting what prominent COVID dissenters actually said—and asking how being spectacularly wrong became, for some, a pathway to influence rather than irrelevance.

Hokkaido University student dies following hydrofluoric acid exposure

A graduate student at Hokkaido University has died after severe exposure to hydrofluoric acid (HF) during an experiment in a science faculty building, the university announced Aug. 27. Two students who attempted to rescue the victim sustained minor injuries but are in stable condition.

Growing Up In An Aging America

The United States has experienced unprecedented, sustained population aging in the last century and a quarter. In 1900, average life expectancy at birth was 47 years. In 1935 and 1965, when Social Security and Medicare were enacted, life expectancy had risen to 62 and 70 years, respectively, while those born today can expect to live a full decade longer, to age 80. This radical extension of life has profoundly affected individuals, institutions, and society, driving changes in societal roles and gender norms and reshaping tradeoffs involving education, marriage, and fertility.

Our Fat Tissue May 'Remember' Obesity, Even After We've Lost Weight

As scientists look for ways to tackle the global obesity crisis, research has established that once the obesity stage is reached, it can be very difficult for many people to find weight loss methods that work long-term.

What's not as clear is exactly why, though it seems obesity leaves some kind of imprint on our bodies that persists even if we start losing weight. A study published earlier this year showed one way that our immune cells carry 'memories' of obesity around with them.

'Slow erosion of human potential.' The trouble with today's high-potency ma*****na

As the use of high-potency ma*****na expands with America's liberalized drug laws, researchers are again asking whether frequent cannabis use dulls drive. The science isn't settled, but acute studies show less effort for reward while intoxicated, and a large 2024 analysis linked adolescent and young-adult use to worse school and work outcomes. Here’s what the evidence actually shows.
