NewsRepurposed antibiotic shows promise against Central Nervous System Tuberculosis
Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have demonstrated that doxycycline, a commonly available and inexpensive antibiotic, can improve survival rates and neurological outcomes in Central Nervous System Tuberculosis (CNS-TB) in a preclinical non-human study. Published in the Journal of Neuroinflammation, the ...

NewsHow life first got moving: nature’s motor from billions of years ago
Research has cast light on the evolutionary origins of one of nature’s first motors, which developed 3.5 billion to 4 billion years ago to propel bacteria. Scientists have created the most comprehensive picture yet of the evolution of bacterial stators.

NewsSecrets of microbial motion: How bacteria swash, glide and shift gears to survive
Two new studies reveal surprising ways microbes move, with implications for human health and disease. The first shows that salmonella and E. coli can ’swash’ across moist surfaces even when their flagella are disabled, while the second probes the T9SS gearbox in flavobacteria.

News Sea stars show surprising resilience after disease outbreak
A decade after sea star wasting disease devastated ochre sea star populations along the U.S. West Coast, new research suggests that the epidemic shifted populations from a stable, adult-dominated state to one marked by fluctuations in sea star sizes and ages.
