Researchers have shown that stress and retrovirus levels are tightly linked to disease in koalas. High KoRV loads make koalas more vulnerable to chlamydia, worsening epidemics in stressed populations. Protecting habitats, careful breeding, and antiviral trials are now being pursued to give koalas a fighting chance at survival. Researchers have shown that stress and retrovirus …
For decades, scientists believed Alzheimer’s was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain immune cells can become clogged with fat, leaving them too weak to fight off disease. By clearing out this fat and restoring the cells’ defenses, …

A 95-million-year-old crocodyliform fossil, affectionately nicknamed Elton, was discovered in Montana by student Harrison Allen. Unlike most crocs, it lived on land and ate a varied diet. The find led to the naming of a new species, Thikarisuchus xenodentes, offering insights into croc evolution and burrow-based fossil preservation. For Allen, it was a life-changing project …

Not drinking enough water could intensify stress responses. Researchers found that under-hydrated individuals had cortisol levels more than 50% higher during stressful situations. Poor hydration didn’t make participants feel thirstier, but it did trigger biological signs of strain. Keeping a water bottle handy could help manage stress and safeguard health. Not drinking enough water could …
