The framework of Adverse Childhood Experiences started with an unexpected finding over 30 years ago. How is our approach changing? 

We know that experiences from our childhood, both good and bad, shape who we become as adults. But, understanding what kinds of early experiences have staying power into adulthood and the wide range of impacts they can have is an emerging science.

In the 1980s, Dr. Vincent Felitti ran a weight loss clini...

Former NIH director Dr. Harold Varmus speaks out about what recent budget cuts and policy changes could mean for science.

One of the areas targeted by President Trump’s administration for cuts has been the National Institutes of Health (NIH). Cost-cutting actions have included the layoffs of some 1,200 NIH employees, the termination of research grants, a pause in the “study sections” that evaluate and award grant funding, and a cap ...

Fungal networks in the ground ferry crucial nutrients to plants. But how do brainless organisms form complex supply chain networks? Also, in this year’s baseball spring training, the new Automated Ball-Strike System is helping settle challenges to home plate pitch calls.

Layoffs at the agency, which releases weather forecasts and monitors extreme weather, could have serious implications. Also, funds for climate and sustainability-focused farming projects have been indefinitely frozen, even though the USDA has already signed contracts.

It’s March 14, or Pi Day, that day of the year where we celebrate the ratio that makes a circle a circle. The Greek letter that represents it is such a part of our culture that it merits our irrational attention.

Joining Host Ira Flatow to help slice into our pi’s is Dr. Steven Strogatz, professor of math at Cornell University and co-host of Quanta Magazine’s podcast “The Joy Of Why.” They talk about how pi was “discovered,” the way...

When you imagine prehistoric life, it’s likely that the first thing that comes to mind are dinosaurs: long-necked Apatosauruses, flying Pterosaurs, big toothy Tyrannosaurs. But what don’t get as much attention are the prehistoric plants that lived alongside them.

Plants, shrubs, and trees played a key part in the food chains of dinosaurs, and many dinosaurs evolved to match the plant life available to them. The Apatosaurus’ long nec...

An international team of researchers used drones to study narwhals and learn more about their behavior. And, a total lunar eclipse will be visible across most of North and South America in the early morning hours of March 14.

A sweeping new study on one of the most beloved insects, maybe the only truly beloved insect—the butterfly—details its rapid population decline in the United States. The new research, published in the journal Science widens the butterfly net and looks at how more than 500 species have fared over the past 20 years.

Researchers found that many populations are taking a nosedive. What’s causing the downswing, and is there anything we ca...

On the very first day of Donald Trump’s second term, he signed an executive order targeting foreign aid programs, especially the U.S. Agency for International Development (USAID).

Comprising less than 0.1% of the federal budget, USAID provides international humanitarian and development aid for poverty eradication, education, disease prevention, and medical programs. The Trump administration has cut off funding for these programs and...

Scientists aren’t always encouraged to be politically active. But recent political interference by the Trump administration has many fired up. And, the Blue Ghost lunar lander, part of NASA’s CLPS initiative, completed the first fully successful commercial moon landing.

Last year, 9,000 deceased donor kidneys were discarded due to storage and time limitations. A kidney “life support” machine could change that. Also, the SS United States will join Florida’s 4,300 artificial reefs—human-made places for fish and other marine life to live. How do these reefs work?

A journalist traveled to five continents to learn about the afterlife of our trash, and why most “recyclable” plastic actually isn’t.

Have you ever gotten to the end of, say, a jar of peanut butter and wondered if it should go in trash or recycling? If it’s worth rinsing out? And where will it actually end up?

Journalist Alexander Clapp had those same questions, and went to great lengths to answer them—visiting five continents to chr...

A study finds that Peto’s Paradox, which states that larger animals are no more likely to get cancer than smaller ones, may not hold up. Also, a nearly complete predator skull was found in the Egyptian desert. Its lineage indicates that it was a top carnivore of the age.

Changes limiting programs, grants, and even the nature of studies are already underway at the NIH, NSF, FDA, CDC, and more.

On President Trump’s first day in office, he signed an executive order to end what he calls “illegal and immoral discrimination programs,” referencing diversity, equity, and inclusion (DEI) in the federal government. The repercussions of this are already being felt across science agencies.

The acting head of the NIH reportedly pushed back against legal guidance to resume grant funding, leaving federal workers in the lurch. Also, though fungi make up a tiny part of the human microbiome, they play an important role in both the prevention and development of many diseases.

Pancreatic cancer is notoriously difficult to treat, and about 90% of diagnosed patients die from the disease. A team at Memorial Sloan Kettering has been working to improve those outcomes by developing a new mRNA vaccine for pancreatic cancer.

A few years ago, the team embarked on a small trial to test the vaccine’s safety. Sixteen patients with pancreatic cancer received it, and even though it was a small study, the results were p...

It’s been an unusually tough winter virus season. Rates of flu-like infections are higher than they’ve been in nearly 30 years. And for the first winter since the start of the COVID-19 pandemic, flu deaths have surpassed COVID deaths. Add to that a higher-than-average year for norovirus, a nasty type of stomach bug.

Then there’s the emerging threat of avian flu. While there is no evidence of human-to-human transmission of the virus,...
