How does a tiny shrimp find its way home in a vast ocean? Study finds it’s down to their cave’s special smell

Researchers from France have shown for the first time that mysid shrimp can distinguish between seawater from their cave of origin and that from nearby caves. This recognition behavior, based on local differences in water-borne odor mixes or ‘chemical seascapes’, is likely what enables the shrimp’s homing behavior when they return each dawn from their foraging trips in open water.

Pallavi Pant - Bridging science and community action to combat air pollution

In honor of this year’s International Day of Clean Air for Blue Skies, we sat down with Dr Pallavi Pant to discuss her work related to air pollution and human health, as well as her thoughts on future directions for the field. With near 15 years of experience in air pollution science, Dr Pant currently leads the Global Health program at the Health Effects Institute in Boston, USA. Her primary focus is on public awareness and engagement, particularly in low- and middle-income countries.

Promising antibiotic candidates discovered in microbes deep in the Arctic Sea

Researchers from Finland and Norway developed a new suite of methods for the screening of antivirulence activity of unknown compounds of bacterial origin. The compounds tested had been derived from actinobacteria living inside invertebrates in the Arctic Sea. They found two interesting compounds with strong antivirulence or antibacterial effects against enteropathogenic E. coli. These results demonstrate the potential of prospecting novel habitats for promising new antibacterial drugs, to solve the current global antibiotics crisis.

Men infected with high-risk types of HPV could struggle with fertility

Researchers from Argentina compared semen quality between men infected with high-risk (HR-HPV) and low-risk (LR-HPV) genotypes of human papillomavirus and HPV negative men. They showed that HR-HPV positive men had higher percentages of dead sperm, a higher level of reactive oxygen species, and a lower count of white blood cells in their semen. These results suggest that HR-HPV positive men, but not LR-HPV positive men, may have lower fertility due to oxidative damage to sperm.
