Popular anti-aging drug combo caused severe brain damage in mice

A drug combo widely explored for anti-aging may actually damage the brain, according to new mouse research showing severe loss of myelin and changes linked to “chemo brain.” Surprisingly, the damaged cells resembled those seen in multiple sclerosis, giving scientists a new lead in understanding—and potentially repairing—the disease.

Hubble Spies Faint Irregular Galaxy

This NASA Hubble Space Telescope image features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy’s low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes. Numerous red, […]

New laser heat treatment could stop blindness before it starts

A new experimental treatment could finally offer hope for millions of people with dry age-related macular degeneration — one of the leading causes of blindness in older adults. Researchers at Aalto University discovered a way to gently heat tissue at the back of the eye using near-infrared light, triggering the cells’ natural “cleanup and repair” systems before major damage occurs.

NASA’s Webb telescope discovers a planet where rock clouds vanish every night

A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like than previously believed.

NASA’s Fermi telescope reveals the power source behind monster supernovae

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.

Blossoming among spoil heaps: how 1,000 years of lead mining gave birth to banks of pansies and pennycress

Calaminarian grassland is a rare habitat where plants thrive in soils contaminated by heavy metals. But should these toxic meadows be protected or allowed to fade away?At first, the small purple flowers are hard to spot in the weak May sunshine. Slowly the drifts of delicate mountain pansies, along with the white rosettes of alpine pennycress, begin to jump out, scattered across an area little bigger than a football pitch, on the banks of the River Allen in Northumberland.This is a pocket of cal

Scientists say guava juice could make iron supplements work better

Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice — especially with iron supplements — experienced noticeable increases in hemoglobin levels. Since guava contains far more vitamin C than oranges, scientists believe it could become a simple, affordable nutrition tool in regions where anemia is widespread.

Earth’s orbital wobble triggered rapid climate chaos during the dinosaur age

New research suggests Earth’s climate can swing wildly on surprisingly short timescales — even during hot, ice-free greenhouse periods. By studying ancient sediments from the Late Cretaceous, scientists uncovered repeating climate shifts tied to tiny changes in Earth’s orbital wobble. These cycles may have repeatedly pushed the planet between humid and arid states every few thousand years.

Scientists are raising new questions about vitamin B12 and cancer

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 — may also be linked to certain cancers or poorer outcomes in cancer patients.

Scientists create supercharged vitamin K that helps the brain heal itself

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 neurons than natural vitamin K alone.
