Sensory and motor brain plasticity is not limited by location
The new function of unused cortical regions is not necessarily determined by the function of nearby cortical regions, according to new research in adults born without one hand.

Study finds topsoil is key harbinger of lead exposure risks for children
Tracking lead levels in soil over time is critical for cities to determine lead contamination risks for their youngest and most vulnerable residents, according to a new study.

A new study by biologists explains how sexual cooperation and bonding evolves in bird species that form pair bonds.
Read moreNon-pharmacologic treatments may be more effective for psychiatric symptoms of dementia
A systematic review and meta-analysis suggests outdoor activities were more clinically effective than anti-psychotic medication for treating physical aggression in patients with dementia. For patients with physical agitation, massage and touch therapy were more efficacious than usual care or caregiver support.
Read moreWomen have substantially less influence on Twitter than men in academic medicine
Women who are health policy or health services researchers face a significant disparity in social media influence compared to their male peers, according to a new study. Although the average number of tweets among all researchers tend to be consistent, women trail behind men in follower counts, regardless of how active they are on Twitter.
Read moreUnlocking the biochemical treasure chest within microbes
An international team of scientists has developed a genetic engineering tool that makes producing and analyzing microbial secondary metabolites — the basis for many important agricultural, industrial, and medical products — easier than ever before, and could even lead to breakthroughs in biomanufacturing.
Read moreLakes worldwide are experiencing more severe algal blooms
The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes. Researchers used 30 years of data from the Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer algal blooms in 71 large lakes in 33 countries on six continents.
Read moreHow to control friction in topological insulators
Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report.
Read moreScientists pinpoint cause of harmful dendrites and whiskers in lithium batteries
Scientists have uncovered a root cause of the growth of needle-like structures — known as dendrites and whiskers — that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire. Such defects are a major factor holding back the batteries from even more widespread use and further improvement.

Cancer cells are masters at avoiding detection, but a new system can make them stand out from the crowd and help the immune system spot and eliminate tumors that other forms of immunotherapies might miss.
