Today's biological science headlines from the sources selected by our team:

Salmonella-infected mice that were given antibiotics became superspreaders
Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators believe they may know why. In a new study, Salmonella-infected mice that were given antibiotics became sicker and began shedding far more bacteria in their feces than they had before.

Built-in billboards: Male bluefin killifish signal different things with different fins
They help fish swim, but fins also advertise a fish's social standing and health. In a new study, researchers report that for the male bluefin killifish (Lucania goodei), each colorful fin presents its own messages to other fish.

Three people infected with Ebola predicted to fly from West Africa every month if no exit screening takes place
Three Ebola-infected travelers are predicted to depart on an international flight every month from any of the three countries in West Africa currently experiencing widespread Ebola virus outbreaks (Guinea, Liberia, or Sierra Leone), if no exit screening were to take place, according to new modeling research.

UCSF researchers identify key factor in transition from moderate to problem drinking
(University of California - San Francisco) A team of UC San Francisco researchers has found that a tiny segment of genetic material known as a microRNA plays a central role in the transition from moderate drinking to binge drinking and other alcohol use disorders.

Once CD8 T cells take on one virus, they'll fight others too
(Brown University) CD8 T cells are known for becoming attuned to fight a specific pathogen ('adaptive immunity'), but a new study shows that in that process they also become first-responders that can fend off a variety of other invaders ('innate immunity'). The findings suggest that innate immunity changes with the body's experience and that the T cells are more versatile than thought.

Amphibians being wiped out by emerging viruses

Scientists tracing the real-time impact of viruses in the wild have found that entire amphibian communities are being killed off by closely related viruses introduced to mountainous areas of northern Spain.

Scientists find 'hidden brain signatures' of consciousness in vegetative state patients

Scientists in Cambridge have found hidden signatures in the brains of people in a vegetative state, which point to networks that could support consciousness even when a patient appears to be unconscious and unresponsive. The study could help doctors identify patients who are aware despite being unable to communicate.

Tarantula toxin is used to report on electrical activity in live cells
Crucial experiments to develop a novel probe of cellular electrical activity were conducted in the Neurobiology course at the Marine Biological Laboratory (MBL) in 2013. Today, that optical probe, which combines a tarantula toxin with a fluorescent compound, is introduced in a paper in the Proceedings of the National Academy of Sciences.

Fish tale: New study evaluates antibiotic content in farm-raised fish
Antibiotics—one of modernity's great success stories—are charms that come with a curse. Their overuse in human and animal populations can lead to the development of resistant microbial strains, posing a dire threat to global health.
