Hidden beneath Arctic waters, beluga whales have long kept their family lives a mystery. By analyzing DNA from more than 600 belugas in Alaska’s Bristol Bay over 13 years, researchers uncovered a surprisingly flexible mating system: both males and females regularly have offspring with different partners over their lifetimes.

Researchers have discovered how microscopic imperfections and atomic vibrations can be used to control a powerful quantum effect in an advanced material. The effect can turn alternating electrical signals from the environment directly into the kind of current electronic devices need, without traditional components. As temperature changes, the signal can even flip direction, giving scientists a ne…

Scientists have uncovered a surprising new way the immune system fights cancer, overturning a core belief that has guided immunology for decades. The research found that when cancer cells shut down a key immune-recognition molecule called MHC I—a common trick used to hide from “killer” T cells—they can actually become more vulnerable to attack by a different group of immune cells known as CD4+ “h…

NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system. Scientists believe the methane was hidden beneath the surface and only emerged after solar…

June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus for viewers in parts of the Americas. The month also marks the start of astronomical summer and the return of spectacular deep-sky targets like the Ri…

Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms. Their experiments revealed that the way vaporized materials cool can dramatically change the particles that eventually form, especially for volatile elements like cesium.

A massive study of more than 600,000 U.S. veterans suggests that popular GLP-1 drugs such as semaglutide may do far more than help with diabetes and weight loss—they could also fight addiction itself. Researchers found that people taking these medications were less likely to develop substance use disorders involving alcohol, nicotine, cannabis, cocaine, opioids, and other drugs, while those alrea…

An ancient mountain cave in the Pyrenees may have served as one of the earliest high-altitude mining camps ever discovered, with evidence of repeated visits spanning thousands of years. The find becomes even more intriguing with the discovery of a child’s remains and clues that deeper excavations could uncover prehistoric burials.

One of the most powerful typhoons ever recorded this early in the Pacific season did more than unleash flooding and extreme winds—it sent enormous ripples all the way into the upper atmosphere. As Super Typhoon Sinlaku rapidly exploded into a category 5-equivalent storm, satellites captured rare gravity waves spreading outward like rings on a pond, visible high above Earth through a faint glow in…

Typhoon Jangmi powered toward southern Japan with heavy rain, strong winds, and a striking appearance from space. Nighttime satellite images revealed a large eye and intricate swirling structures within the storm. As Jangmi intensified, its outer bands spread over land, raising concerns about flooding and prolonged downpours across parts of Japan.

Scientists have developed an experimental diabetes and obesity pill that works in a completely different way from drugs like Ozempic. Rather than reducing hunger, it activates metabolism in skeletal muscle, helping lower blood sugar and increase fat burning while preserving muscle mass. Early clinical results suggest the treatment is safe and well tolerated.

A newly identified group of amygdala neurons appears to play a central role in anxiety and social behavior. Restoring normal activity in this tiny brain circuit reversed anxiety and social deficits in mice, revealing a promising new target for future treatments.

French fries may be the real potato problem. A large study tracking more than 205,000 people for nearly 40 years found that eating three servings of fries per week was linked to a 20% higher risk of developing type 2 diabetes, while baked, boiled, or mashed potatoes showed no significant increase in risk. The research also found that swapping potatoes for whole grains lowered diabetes risk, while…

Researchers discovered a way to reverse the direction of energy flow in turbulence, challenging a theory that has stood for more than 80 years. The finding could open new possibilities for controlling ocean currents, improving medical technologies, and enhancing climate forecasting.

Scientists have confirmed that a mysterious Utah earthquake first detected in 1979 really did occur nearly 90 kilometers underground—far deeper than anyone thought earthquakes could happen beneath a continent. By reanalyzing decades of seismic data, researchers identified a rare class of "continental mantle earthquakes" occurring deep in Earth’s upper mantle, where rock is expected to slowly flow…
