Salmonella-infected mice that were given antibiotics became superspreaders

Salmonella-infected mice that were given antibiotics became superspreaders

Salmonella-infected mice that were given antibiotics became sicker and began shedding far more bacteria in their feces than they had before. Some people infected with pathogens spread their germs to others while remaining symptom-free themselves Continue reading

Mental rest and reflection boost learning, study suggests

Mental rest and reflection boost learning, study suggests

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they’ve learned before, may boost later learning. Scientists have already established that resting the mind, as in daydreaming, helps strengthen memories of events and retention of information. In a new twist, researchers at The University of Texas at Austin have shown that the right kind of mental rest, which strengthens and consolidates memories from recent learning tasks, helps boost future learning.

Developing invisible implantable medical sensor arrays, a team of University of Wisconsin-Madison engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain. The team described its technology, which has applications in fields ranging from neuroscience to cardiac care and even contact lenses, in the Oct. 20 issue of the online journal Nature Communications Continue reading

Scientists restore hearing in noise-deafened mice, pointing way to new therapies

Scientists restore hearing in noise-deafened mice, pointing way to new therapies

Scientists have restored the hearing of mice partly deafened by noise, using advanced tools to boost the production of a key protein in their ears. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging. In a new paper in the online journal eLife , the team from the University of Michigan Medical School’s Kresge Hearing Research Institute and Harvard University report the results of their work to understand NT3′s role in the inner ear, and the impact of increased NT3 production on hearing after a noise exposure.

Improving bladder function among people with spinal cord injuries

Improving bladder function among people with spinal cord injuries

People who have suffered spinal cord injuries are often susceptible to bladder infections, and those infections can cause kidney damage and even death. New UCLA research may go a long way toward solving the problem. A team of scientists studied 10 paralyzed rats that were trained daily for six weeks with epidural stimulation of the spinal cord and five rats that were untrained and did not receive the stimulation.

Sugared soda consumption, cell aging associated in new study

Sugared soda consumption, cell aging associated in new study

Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to UC San Francisco researchers who found in a new study that drinking sugary drinks was associated with cell aging. The study revealed that telomeres — the protective units of DNA that cap the ends of chromosomes in cells — were shorter in the white blood cells of survey participants who reported drinking more soda.

Scientists find ‘hidden brain signatures’ of consciousness in vegetative state patients

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. Continue reading
