In a study published in Frontiers in Ecology and Evolution, Spanish researchers analysed rare amber pieces containing multiple species to determine whether close proximity reflects ancient ecological relationships or mere coincidence. The findings shed new light on the behaviour of early ants that lived alongside the dinosaurs.

A new study has found that as super agers (a unique group of adults over age 80 whose performance on tests of episodic memory was equal to or better than that of people in their 50s) age their brain continues to generate new neurons in the hippocampus at much higher levels than older adults and even younger individuals.

A flexible school start model could significantly improve teenagers’ sleep, health and academic performance. Researchers from the University of Zurich report in the Journal of Adolescent Health that allowing students to begin classes later led to an average of 45 minutes more sleep per school day, alongside measurable gains in well-being and learning outcomes.

A team of food scientists co-fermented the enzyme-treated kombu with lactic acid bacteria and an aroma-producing yeast to produce a novel probiotic kombu-based blend that is both healthier and more flavorful.

Researchers led by the University of Bath have developed a sunlight-activated catalyst capable of breaking down persistent “forever chemicals” in water. Reported in RSC Advances, the carbon-based photocatalyst targets PFAS and converts them into less harmful substances under neutral environmental conditions.

A new poll by the Physicians Committee for Responsible Medicine has found out that almost half of the adults in the USA are not aware that eating processed meat increases colon cancer risk. On the other hand, research says that plant-based diet reduces the risk by 22 %.

Altering the gut microbiome could help the brain recover after traumatic injury. Researchers at Houston Methodist report in Communications Biology that short-term antibiotic treatment reduced neuroinflammation and tissue damage in experimental models of traumatic brain injury.

A study has examined how sleep affects sedentary behavior and overall activity in teenagers. They found that kids that sleep more tend to spend less time sitting around on the couch.

What makes spiders so unsettling? Researchers at the University of Nebraska–Lincoln are using eye-tracking technology to uncover which visual cues trigger discomfort and avoidance — and how this knowledge could improve phobia treatment, conservation and our understanding of human reactions to the natural world.

Researchers from the USA are spearheading a project to test whether reducing DNA-triggered inflammation can help older adults stay healthier for longer. The federal Advanced Research Projects Agency for Health has also awarded 22 million dollars to the project.
