Early metabolism may have begun as a mix of metal and enzyme catalysis before bacteria and archaea independently evolved into free-living cells. Four billion years ago, the chemistry that eventually became life may have been unfolding around hydrothermal vents, where naturally occurring metals helped drive reactions before cells possessed the full machinery they use today.

85% of Atypical Alzheimer’s Patients May Not Qualify for Treatment
Current treatment criteria may exclude many people with atypical Alzheimer’s disease even when they remain in relatively early stages. For some people with Alzheimer’s disease, memory loss is not the first warning sign. Problems with vision, language, planning, or movement can appear earlier, and new research suggests that these less typical symptoms may prevent many […]

A Cannabis-Based Drug Dramatically Reduced PTSD Nightmares
A new approach to treating severe sleep disorders. For many people with post-traumatic stress disorder (PTSD), going to sleep can mean reliving a traumatic experience with frightening intensity. These recurring nightmares can cause severe sleep loss and even create fear of going to bed, while existing medications often provide limited relief. Researchers at Charité – […]
Never-Before-Seen Vortices Are Swirling Across the Sun
The world’s largest solar telescope and advanced computer simulations revealed vortices that are reshaping our understanding of the Sun. Across the Sun’s visible surface, hot plasma is constantly rising, cooling, and sinking. At the edges of these churning regions, researchers have now resolved tiny swirling structures that may help explain how the Sun twists, stores, […]

Something May Be Flowing Beneath Pluto’s Giant Heart-Shaped Glacier
Researchers used New Horizons images to identify evidence that liquid nitrogen may have flowed from beneath Pluto’s famous heart-shaped glacier. Dark markings across part of Pluto’s enormous heart-shaped glacier may record something unexpected beneath its frozen surface: liquid nitrogen moving upward and briefly flowing across the ice. Using observations from NASA’s New Horizons spacecraft, researchers […]
Industrial Chicken Farming Is Supercharging the Spread of a Dangerous Foodborne Bacterium
The global expansion of chicken farming has created conditions that allow Campylobacter to spread, mix and adapt more readily. Commercial poultry farms now hold billions of chickens, creating a vast habitat where bacteria can move, mix and adapt. An analysis from the Ineos Oxford Institute for Antimicrobial Research at the University of Oxford found that […]
