Tadpoles try to flee dangerous virus in their pond by growing much faster than normal

Researchers from the US studied the plasticity in growth and development of wood frog larvae in response to the emerging disease ranavirus, which can kill off the entire population of ponds. They showed that tadpoles in infected ponds speed up the rate of growth and progression through the immature stages. They hypothesize that this plasticity boosts their physical condition and hence immune response to ranavirus, and allows them to metamorphose earlier and escape infection.

Mere whiff of penguin poo pushes krill to take frantic evasive action

Scientists have shown for the first time that Antarctic krill show a stereotypical reaction in the presence of guano from Adélie penguins: they swim faster and make more turns over greater angles. It is unknown to what kind of water-borne chemical cues they respond, but the authors speculate that this behavior might be a universal escape response to the excreta of predators, irrespective of species.

Suicide, the music industry, and a call to action

Dr George Musgrave is both a musician and an academic, with first-hand experience of the music industry’s challenges. In this guest editorial, inspired by their moving and urgent new article in Frontiers in Public Health, he and co-author Dr Dorian Lamis, who is a clinical psychologist and suicide prevention expert, turn the spotlight on the toll of death by suicide in the music industry, and call for immediate action to support vulnerable artists.

Dangerous bacteria lurk in hospital sink drains, despite rigorous cleaning

Researchers from Spain sampled sink drains from different wards in a single modern university hospital where state-of-the-art cleaning protocols are adhered to. Through culturing and DNA barcoding, they found 67 species of bacteria. These included Klebsiella, Enterobacter, and Pseudomonas aeruginosa, notorious for their potential to cause healthcare-associated infections. Several strains detected proved resistant to modern antibiotics, including cephalosporins and carbapenems. Sink drains thus appear to function as reservoirs for known and emerging pathogens of concern.
