New antibiotic candidate shows promise
Tests in lab dishes and mice suggest an experimental compound called teixobactin can kill staph, TB microbes and other bacteria.
- Animals
How many wildebeest? Ask a satellite
High-resolution satellite imagery could offer a reliable way to count large mammals in open habitats from space.
- Neuroscience
PET scans hint at brain’s reorganization after injury
Imaging monkeys’ brains after strokelike injury is giving scientists clues to how neurons reorganize themselves so the animals can move again.

Bowhead whales may unlock the secrets to a long, healthy life
Analyzing the genome of the bowhead whale may help scientists understand how the animals live for more than 200 years.
- Animals
Little African cats need big parks
Protecting African wildcats requires large protected areas free of feral cats to avoid the risk of the wild species disappearing through hybridization.
- Animals
