Kelp forests bounce back faster from marine heatwaves when shielded inside Marine Protected Areas. UCLA researchers found that fishing restrictions and predator protection strengthen ecosystem resilience, though results vary by location.
Scientists unlock the gene that lets bearded dragons switch sex
Two independent research teams have unveiled near-complete reference genomes of the central bearded dragon, a reptile with the rare ability to change sex depending on both chromosomes and nest temperature. Using next-generation sequencing technologies from China and Australia, the projects uncovered the long-sought genetic basis of sex determination in this...
Tiny microbes may secretly rewire the brain before birth
MSU researchers discovered that microbes begin shaping the brain while still in the womb, influencing neurons in a region critical for stress and social behavior. Their findings suggest modern birth practices that alter the microbiome may have hidden impacts on brain development.
Scientists reveal how just two human decisions rewired the Great Salt Lake forever
Scientists found that Great Salt Lake’s chemistry and water balance were stable for thousands of years, until human settlement. Irrigation and farming in the 1800s and a railroad causeway in 1959 created dramatic, lasting changes. The lake now behaves in ways unseen for at least 2,000 years.
A record-breaking antenna just deployed in space. Here’s what it will see
NASA and ISRO s NISAR satellite has just reached a major milestone: the successful deployment of its enormous 39-foot antenna reflector in orbit. Folded up like an umbrella during launch, the reflector is now fully extended and ready to support NISAR s groundbreaking radar systems. This record-breaking satellite will monitor...
NASA’s PREFIRE satellites reveal a secret glow escaping from our planet
With its two tiny CubeSats, NASA’s PREFIRE mission is capturing invisible heat escaping from Earth, offering clues to how ice, clouds, and storms influence the climate system. The insights could lead to better weather forecasts and a deeper understanding of global change.
Scientists just found a hidden factor behind Earth’s methane surge
Roughly two-thirds of all atmospheric methane, a potent greenhouse gas, comes from methanogens. Tracking down which methanogens in which environment produce methane with a specific isotope signature is difficult, however. UC Berkeley researchers have for the first time CRISPRed the key enzyme involved in microbial methane production to understand the...
Trojan horse bacteria sneak cancer-killing viruses into tumors
Scientists have engineered a groundbreaking cancer treatment that uses bacteria to smuggle viruses directly into tumors, bypassing the immune system and delivering a powerful one-two punch against cancer cells. The bacteria act like Trojan horses, carrying viral payloads to cancer’s core, where the virus can spread and destroy malignant cells....
One gene completely changed how these flies fall in love
By flipping a single genetic switch, researchers made one fruit fly species adopt the gift-giving courtship of another, showing how tiny brain rewiring can drive evolutionary change.
Great white sharks have a DNA mystery science still can’t explain
Once on the brink during the last ice age, great white sharks made a remarkable recovery globally, but their DNA reveals a baffling story. Classic migration explanations fail, leaving scientists with a mystery that defies reproductive and evolutionary logic.
