What happens when a really gargantuan star — one hundreds of times bigger than our sun — blows up? Although a theory developed years ago describes what the explosion of such an enormous star should look like, no one had actually observed one — until now.

Humans and mice have previously unknown and potentially critical differences in one of the genes responsible for Duchenne muscular dystrophy. Researchers have found that two major features of a key DMD gene are present in most mammals, including humans, but are specifically absent in mice and rats, calling into question the use of the mouse [...]

Scientists have described a new, highly pragmatic approach to the identification of molecules that prevent a specific type of immune cells from attacking their host. The findings add a powerful new tool to the ongoing search for potential treatments for autoimmune diseases, such as multiple sclerosis (MS), as well as blood cancers, such as myeloid [...]

Researchers have made an “unexpected” dual discovery that could open new avenues for treating Ichthyophthirius multifiliis, or “Ich”, a devastating single-celled protozoan parasite that commonly attacks freshwater fish.
A new study suggests that changes in children’s sleep patterns that typically occur between the ages of 11 and 12 years are evident before the physical changes associated with the onset of puberty.

Feeding birds in winter is a most innocent human activity, but it can nonetheless have profound effects on the evolutionary future of a species, and those changes can be seen in the very near term.

Glial cells, which help neurons communicate with each other, can leave the central nervous system and cross into the peripheral nervous system to compensate for missing cells, according to new research. The animal study contributes to researchers’ basic understanding of how the two nervous systems develop and are maintained, which is essential for the effective [...]

A new study has revealed that MRI is a highly accurate means of identifying placenta accreta, a potentially life-threatening and increasingly common condition that is the leading cause of death for women just before and after giving birth.
