2024/06/05

June 6, 1944 the Allied Forces stormed the beaches of Normandy and took the Nazis by surprise in the largest sea-to-land invasion in history. This would be remembered as D-Day and would ultimately lead to the end of World War II in Europe. However, this planned attack wouldn't have been possible without deep knowledge of ocean tides! We get into the whole story, including why tides sit at the intersection of astronomy and marine ecology — and why understanding tides are key to a greener future.Want

A silky shark named Genie traveled from the Galapagos Islands out to the open ocean and back – over 17,000 miles – over the course of a year and a half. That's an average of 31 miles per day, making Genie's journey the longest recorded migration for a silky shark. Marine scientist Pelayo Salinas de León and his team named Genie in honor of the late marine biologist Eugenie Clark – also known as "The Shark Lady." She devoted her life to the study of sharks and to improving their reputation. Have

Each year 84,000 people in the U.S. are diagnosed with melanoma. About 90% of these skin cancers are linked to the ultraviolet radiation from the sun. Sunscreen does protect the skin, but dermatologists have found six very common mistakes people make when it comes to using it. NPR science correspondent Allison Aubrey talks to host Regina G. Barber about the science behind sunscreen and how to avoid making these mistakes this summer. They also get into which sunscreens may be better than others.Have

Baobabs are sometimes called the "tree of life" with their thick trunks, crown of branches and flowers that only open at twilight. But theories about their geographic origin was divided among three places: the savannas of sub-Saharan Africa, the Kimberley region of western Australia and the dry forests of the island nation of Madagascar. To solve this mystery, a global research team led by scientists at the Wuhan Botanical Garden at the Chinese Academy of Sciences examined high-quality genomic data

Scientists at the National Oceanic and Atmospheric Administration observed a cluster of sunspots on the surface of the sun this week. With them came solar flares that kicked off a severe geomagnetic storm. That storm is expected to last throughout the weekend as at least five coronal mass ejections — chunks of the sun — are flung out into space, towards Earth! NOAA uses a five point scale to rate these storms, and this weekend's storm is a G4. It's expected to produce auroras as far south as

It's not unusual for siblings to quibble over ownership of something — a cherished toy, a coveted seat in the car — or whose fault something is. If you're Mercedes Sheen, you not only spent your childhood squabbling with your sister over your memories, you then turn it into your research career. Mercedes studies disputed memories, where it's unclear who an event happened to. It turns out these memories can tell us a lot about people — they tend to be self-aggrandizing — and how the human brain

Wildlife ecologists have seen white-tailed deer expanding their range in North America over many decades. And since the early-2000s these deer have moved north into the boreal forests of western Canada. These forests are full of spruce and pine trees, sandy soil and freezing winters with lots of snow. They can be a harsh winter wonderland. And ecologists haven't known whether a warmer climate in these forests or human land development might be driving the deer north. A recent study tries to

No matter what you're doing right now – sitting, standing, walking – you're moving. First, because Earth is spinning around on its axis. This rotation is the reason we have days. Second, because Earth and other planets in our solar system are orbiting the sun. That's why we have years. Third, you're moving because the sun and the rest of our solar system is orbiting the center of the Milky Way galaxy at over 500,000 miles per hour.
