How birds can detect the Earth's magnetic field

Researchers at Lund University discovered that Cry4 protein in birds' eyes is a key magnetoreceptor, providing constant levels throughout the day. This finding supports the idea that other animals have magnetic receptors and may aid in developing new navigation systems.

New blood test found to predict onset of TB up to two years in advance

A new blood test has been developed to predict tuberculosis (TB) development in high-risk individuals, such as those living with active TB, up to two years before its onset. The 'RISK4' signature measures the expression levels of four genes associated with inflammatory responses and shows improved accuracy compared to existing tests.

School lunch decisions made by the child and not the parent

A new study published in the Journal of Nutrition Education and Behavior found that children are often the primary decision maker for school lunches and packed lunches, prioritizing their own enjoyment and food preferences. The study's findings suggest that parents' anxieties and reassurances play a significant role in accommodating ch...

New cellular insights in bone development

A team of engineers at Washington University in St. Louis studied the formation of new bone and teeth, discovering that miniscule gaps in collagen's fiber structure facilitate the nucleation of calcium phosphate. The findings provide a new view into the current theory of calcium phosphate nucleation in confined spaces.

1C rise in atmospheric temperature causes rapid changes to world's largest High Arctic lake

A one-degree temperature increase led to drastic changes in Lake Hazen's ecology, including increased glacial meltwater and fine sediment, affecting light penetration and biological productivity. The findings document an unprecedented shift in the lake's ecosystem, challenging scientists' expectations of its response to climate warming.

Nova-like explosion of spinning live bacteria explained

Researchers discovered that when live bacteria are spun at high speeds, they aggregate and form a dense disk, but when the spinning stops, the disk collapses due to imperfections on its surface. The resulting rapid movement of bacteria away from their origin of rotation creates an explosion-like effect.

'Sleeping' stem cells could aid brain repair

Scientists at the University of Cambridge have discovered a new type of 'sleeping' stem cell in the brain that has a high potential for repair following brain injury or disease. The G2 quiescent stem cell can awaken and produce key brain cells, such as neurons and glia, faster than previously identified quiescent stem cells.
