Astronomers finally solve the gamma-Cas X-ray mystery after 50 years

A decades-old cosmic mystery has finally been cracked: the strange X-rays coming from the bright star gamma-Cas are caused by a hidden stellar companion feeding off it. Using cutting-edge observations from the XRISM space mission, astronomers discovered that an unseen white dwarf star is siphoning material from gamma-Cas, heating it to extreme temperatures and producing powerful X-ray emissions. This breakthrough resolves a puzzle that has baffled scientists since the 1970s and sheds new light on how these unusual stellar pairs form and evolve.

This donut-shaped discovery just shattered a 150-year math rule

A 150-year-old rule in geometry has been proven wrong. Mathematicians found two different doughnut-shaped surfaces that look identical when measured locally but are actually different overall. For decades, researchers suspected this might be possible but couldn’t prove it—until now. The breakthrough reshapes how mathematicians understand the relationship between local measurements and global form.

PFAS found in most americans linked to rapid biological aging

“Forever chemicals” known as PFAS have quietly infiltrated everything from nonstick pans to food packaging—and now new research suggests some of them may be speeding up the aging process itself. In a nationally representative U.S. study, two lesser-known PFAS compounds, PFNA and PFOSA, were found in 95% of participants and strongly linked to faster biological aging in men aged 50 to 64.

A supervolcano nearly wiped out humanity 74,000 years ago, but humans did something incredible

The Toba supereruption 74,000 years ago was so massive it may have plunged Earth into years of darkness and cold, leading some scientists to believe humanity nearly went extinct. Yet archaeological evidence from Africa and Asia suggests early humans were far more resilient than once thought. Instead of disappearing, some communities adapted with new tools, new survival strategies, and remarkable flexibility. The disaster may not have destroyed humanity — it may have revealed just how tough humans really are.

Vitamin D boosts breast cancer treatment success by 79%

A daily vitamin D supplement may quietly supercharge chemotherapy. In a small study, women who took low doses alongside treatment were far more likely to see their cancer vanish than those who didn’t. Since vitamin D also supports immune function—and many patients are deficient—it could be playing a bigger role than expected. Scientists say this affordable approach deserves much deeper investigation.

Scientists just turned light into a remote control for crystals

NYU researchers have found a way to use light to control how microscopic particles assemble into crystals, effectively turning illumination into a tool for shaping matter. By adding light-sensitive molecules to a liquid filled with tiny particles, they can adjust how strongly the particles attract or repel one another simply by changing the light’s intensity or pattern. This allows them to trigger crystals to form, dissolve, or even be reshaped in real time.

Scientists discover hidden sugar layer behind psoriasis

A gel-like sugar coating on immune cells has been found to play a starring role in psoriasis. Researchers discovered that immune cells shed this outer layer to help them exit the bloodstream and enter inflamed skin. This challenges the long-held idea that only blood vessel walls changed during this process. The finding could help guide new therapies aimed at controlling harmful inflammation.

Weight loss drug Ozempic cuts depression, anxiety, and addiction risk

GLP-1 medications like semaglutide (Ozempic) may offer unexpected mental health benefits alongside weight loss. A large study found major drops in depression, anxiety, and psychiatric-related hospital visits among users. Even substance use disorders were significantly lower during treatment. Researchers suspect both lifestyle improvements and direct brain effects could be at play.

Scientists discover hidden brain switch that tells you to stop eating

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send signals to astrocytes that then activate fullness neurons. This newly discovered pathway could lead to innovative treatments for obesity and eating disorders.

Your DNA has a secret “second code” that decides which genes get silenced

Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that cells can detect less efficient genetic instructions and selectively silence them. A protein called DHX29 plays a key role in this process by identifying and suppressing weaker messages. This finding reveals a hidden layer of control in how genes are used.
