Bacterial classification has been given a complete makeover using an evolutionary tree based on genome sequences.

Tiny tunnels run from skull bone marrow to the lining of the brain and may provide a direct route for immune cells responding to injuries caused by stroke and other brain disorders.

Researchers have deciphered the role of a key protein that the malaria parasite Plasmodium falciparum uses to obtain nutrients while infecting red blood cells.

TREM-1, or triggering receptor expressed on myeloid cells-1, is known to help turn up inflammation short-term to help us deal with external invaders. But scientists now report the first evidence that when activated by chronic offending agents, like obesity and hepatitis, TREM-1 instead contributes to a destructive level of inflammation that results in liver damage and possibly cancer.

After 10 years in the making, a urine diagnostic test that detects parasitic worms that cause blindness is ready to go.

Researchers have discovered a previously unknown reason for drug resistance in a common subtype of melanoma, one of the deadliest forms of cancer, and in turn, have found a new therapy that could prevent or reverse drug resistance for melanoma patients with a particular gene mutation.

The master regulators of gut stem cells, called intestinal myofibroblasts, have pumps that protect them, and thus the gut, from the toxic effects of a wide range of compounds.

This study is a first step towards personalized risk assessment so we can better inform people about steps to improve their future brain health.

Researchers establish a new method for objectively measuring axon degeneration, potential applications are widespread.

“We really don’t understand what makes the human brain special.”
