Every morning when the sun comes up, the ocean ground is radically cleaned. As soon as the first rays of sunlight find their way into the water, the microalgae "Nitzschia cf pellucida" start their deadly 'morning hygiene'. The algae, the size of only some few micrometers, wrap themselves and their surroundings in a highly toxic poison: cyanogen bromide, a chemical relative of hydrocyanic ac

Among medical mysteries baffling many infectious disease experts is exactly how the deadly pneumonic plague bacterium, Yersinia pestis, goes undetected in the first few day of lung infection, often until it's too late for medical treatment.

School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress.

Scientists have for the first time measured how fast large-scale evolution can occur in mammals, showing it takes 24 million generations for a mouse-sized animal to evolve to the size of an elephant.

Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons.

Scientists have long believed that human speech is processed towards the back of the brain's cerebral cortex, behind auditory cortex where all sounds are received — a place famously known as Wernicke's area after the German neurologist who proposed this site in the late 1800s based on his study of brain injuries and strokes.

Think of them as a group of guys, hanging out together, but not spending much time with the ladies, nor getting much "action." Except these "guys" are forked fungus beetles.

Wildlife health experts from the Wildlife Conservation Society have published evidence which supports the conclusion that Mongolian gazelles—one of the most populous large land mammals on the planet—are not a reservoir of foot-and-mouth disease (FMD), a highly contagious viral disease that threatens both wildlife and livestock in Asia.

Age-related delays in neural timing are not inevitable and can be avoided or offset with musical training, according to a new study from Northwestern University. The study is the first to provide biological evidence that lifelong musical experience has an impact on the aging process.

To the lengthy list of serendipitous discoveries – gravity, penicillin, the New World – add this: Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment. Better still, they've also discovered how to correct the problem.
