A study suggests that exposure to pollution from landscape fires during pregnancy is linked to low birth weights in low and middle-income countries.

New insight on how cells migrate through the body could have implications for developing new ways to slow or prevent the spread of cancer.

A new study shows that toothed whales rapidly adjust their echolocation behaviour to track fast and unpredictable prey movements, with response times similar to human vision.

A drug repurposing study of tamoxifen for a deadly form of fungal meningitis suggests it has no benefits in clearing the infection more quickly.

Scientists have isolated a promising form of commensal bacteria in cats that could be used as a bacteriotherapy for hard-to-treat skin infections.

Researchers have shed new light on evolutionary processes in the last 50,000 years that have allowed some disease-causing genes to persist in human populations.

A study suggests that cells involved in the sexual development of Aspergillus fungi also play a role in producing chemicals that deter hungry predators.

A genetic analysis suggests that a rare blood cancer that affects immune T cells may be caused by exposure to smoking and aging-related mutations acquired during the early stage of production of new blood cells.

A new study shows how a type of protein acts as part of a previously unrecognised epigenetic mechanism that helps yeast adapt more quickly to changing circumstances.

A review of the role of host tolerance in emerging infectious diseases highlights the need for a multidisciplinary research effort combining immunology, ecology and evolution.
