Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated. By combining vitamin K with components related to vitamin A, the researchers developed compounds that were about three times more effective at turning neural stem cells into neu…

Humanity may already be living far beyond what Earth can sustainably support, according to a sweeping new study analyzing more than 200 years of population and environmental data. Researchers found that while population growth once fueled innovation and expansion, the trend shifted decades ago as the planet’s resources became increasingly strained.

Researchers at Texas A&M have developed a nasal spray that appears to reverse brain aging by calming inflammation and restoring the brain’s energy systems. After just two doses, memory and cognitive function improved for months, raising hopes for future treatments targeting dementia and brain fog.

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and forces of the universe. By studying incredibly rare particle transformations called “penguin decays,” researchers found behavior that doesn’t fully match theoretical predictions, raising the possibility t…

Vitamin B12 has long been seen as a health hero, helping the body make red blood cells, repair DNA, and keep nerves functioning properly. But scientists are discovering that the story may be more complicated than simply “more is better.” While too little B12 can damage DNA and raise cancer risk, some studies suggest that extremely high levels — especially from long-term high-dose supplements — ma…

Scientists uncovered evidence that human blood cells may trace their origins back to single-celled ancestors that lived 700 million years ago. By rebuilding the evolutionary family tree of blood cells, the team revealed how today’s immune system grew from some of Earth’s earliest life forms.

When a queen wasp suddenly disappears, her colony doesn’t calmly choose a successor — it erupts into chaos. Researchers found that female wasps immediately begin battling for power, shattering the colony’s social order in a frenzy of aggression. But while some fight for the throne, others quietly become the colony’s unsung heroes, stepping up to gather food and care for the young so the society d…

Hidden deep in the towering mountains of the Himalayas, one of Asia’s most mysterious venomous snakes has been keeping a major secret for over 160 years. Scientists have now discovered that the so-called Himalayan pit viper is not just one species, but actually five separate species — including three completely unknown to science until now.

A sweeping new study of wild snakes in the southeastern US has revealed a hidden health crisis slithering beneath the surface. Researchers found that many snakes are carrying multiple infections at once, with a dangerous fungal disease called ophidiomycosis — or snake fungal disease — emerging as one of the biggest threats. Pygmy rattlesnakes appeared especially vulnerable, frequently infected wi…

A new AI-powered chip from UC Davis can analyze light and chemicals using a device tiny enough to fit almost anywhere. By combining smart silicon sensors with machine learning, it achieves lab-style spectral analysis without the bulky equipment.

Scientists have created a global “treasure map” for rare earth elements by uncovering where the strange volcanic rocks that contain them are most likely to form. By combining thousands of rock samples with seismic images of Earth’s deep interior, the team discovered that these metal-rich rocks tend to appear along the ancient, thick roots of continents. These unusual rocks, once seen as geologica…

NASA’s Psyche spacecraft just used Mars as a giant gravitational slingshot to continue its journey toward a strange metal rich asteroid. The close flyby boosted the spacecraft’s speed by about 1,000 mph while also producing rare crescent images of Mars glowing through its dusty atmosphere.

Scientists used some of the most advanced plasma simulations ever created to uncover how the universe builds enormous magnetic fields out of turbulence. The discovery could reshape our understanding of stars, black holes, neutron star collisions, and dangerous solar eruptions.

Scientists believe a dust-filled ring just outside Jupiter acted like a cosmic “planetesimal factory,” producing multiple generations of early space rocks with very different compositions. The discovery may finally explain the origins of several mysterious meteorite types that have survived since the birth of the Solar System.

USC researchers have identified potential new drug compounds that may reduce the brain inflammation linked to Alzheimer’s disease, especially in people with the high-risk APOE4 gene. The compounds target cPLA2, an enzyme that seems to fuel harmful inflammation while also being important for normal brain activity.
