Scientists at Université de Montreal's Department of Biochemistry and Molecular Medicine design better molecules that make it harder for plasmids to move between bacteria.
Many musicians suffer ear damage. Professional orchestras have therefore taken measures in recent years to reduce the sound levels. Studies now reveal that physical measures, like placing screens or creating more space, have little effect. This is due to one's own instrument contributing just as much to the sound level that reaches the ear as all the orchestra's instruments together. The only solution that really helps is earplugs, for professionals but also amateurs playing at home.
A team of neuroscientists at the University of Pennsylvania has constructed the first whole-brain map of electrical connectivity in the brain based on data from nearly 300 neurosurgical patients with electrodes implanted directly on the brain. The researchers found that low-frequency rhythms of brain activity, when brain waves move up and down slowly, primarily drive communication between the frontal, temporal and medial temporal lobes, key brain regions that engage during memory processing.
Natural habitats play a vital role in helping other plants and animals resist heat stresses ramping up with climate change -- at least until the species they depend on to form those habitats become imperiled.
In a Journal of Advanced Nursing study, female gender and personal burnout were linked with impaired sleep quality among nurses.
In a Journal of the American Geriatrics Society study of community-dwelling individuals aged 70 to 90 years who were participating in the Jerusalem Longitudinal Study, leaving the house daily was linked with a lower risk of dying over an extended follow-up period, independent of social, functional, or medical factors.
A new HIV Medicine study identified several barriers to routine HIV testing in emergency departments and acute medical units in the UK and US.
Media reports have depicted vaginal birth as harmful and cesarean delivery as protective of sexuality, but research does not support these depictions.
Alzheimer's disease is caused by tangles in the brain made up of malfunctioning aggregated Tau proteins. Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published in Nature Communications and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.
Risk for aging-related diseases such as heart disease and diabetes was significantly higher among thyroid cancer survivors in Utah than it was among age-matched, cancer-free individuals, with those diagnosed before age 40 having the highest risk for some of the diseases.
