NASA's James Webb Space Telescope reveals a strange atmosphere on a hellish lava planet

NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds.

Common constipation drug may help clear depression brain fog

An existing constipation drug may have an unexpected new use: helping clear the "brain fog" that often lingers after depression. In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week performed better on tests of memory, attention, and thinking speed than those who received a placebo. The drug targets a serotonin receptor found in both the gut and the brain, and researchers saw no significant side effects.

Why have humans collected crystals for 780,000 years? Chimpanzees may hold the answer

Chimpanzees showed a remarkable attraction to crystals, choosing them over ordinary stones and studying them with intense curiosity. The results suggest that the same unusual features may have fascinated early humans long before crystals had any practical use.

Chewing bubble gum after beetroot may help lower blood pressure

A new study found that chewing sugary gum after eating nitrate-rich vegetables or drinking beetroot juice helped the body produce more beneficial nitrite, leading to a temporary drop in blood pressure. Researchers hope the discovery will lead to healthier ways to enhance the cardiovascular and performance benefits of dietary nitrate without relying on sugar.

New dark matter theory could solve multiple cosmic mysteries at once

Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gravitational lensing.

Scientists discover why peach fuzz can suddenly make you itch

A newly discovered network of fine hairs and specialized nerve cells appears to form a dedicated system for sensing mechanical itch, offering fresh insight into why chronic itching occurs. Because humans show signs of having the same pathway, the research could pave the way for more effective treatments for conditions such as eczema.

Scientists discover a hidden heart valve risk linked to gum disease

Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play a role in reducing the risk of this serious heart condition.
