Yarn weaved from carbon nanotubes monitors brain control of organ functions in rats, paves way for disease diagnosis and treatment at single nerve level.
These days, many hospital patients get medicine or nutrition delivered straight into their bloodstream through a tiny device called a PICC. In just a decade, it’s become the go-to device for intravenous care. But a new study finds that one in every four times a PICC gets inserted, the patient didn’t need it long enough to justify the risks that it can also pose.
Some people with a certain type of hearing loss may be more likely to also have the memory loss and thinking problems called mild cognitive impairment, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018. Hearing loss is one of the most common disabilities in elderly people, affecting about one-third of people over age 65.
Lithium ions have to travel through layers of molecules in the electrolyte liquid before they can enter or leave a lithium-ion battery electrode. Tweaking this process could help batteries charge faster.

Forests across the United States—and especially forest soils—store massive amounts of carbon, offsetting about 10 percent of the country's annual greenhouse gas emissions and helping to mitigate climate change.
Commonly used ICU risk scores can be "repurposed" as continuous markers of severity of illness in critically ill patients—providing ongoing updates on changes in the patient's condition and risk of death, according to a study in the March issue of Critical Care Medicine, official journal of the Society of Critical Care Medicine (SCCM). The journal is published by Wolters Kluwer.
Led by researchers at University of California San Diego School of Medicine, a diverse team of neuroscientists and surgeons successfully grafted human neural progenitor cells into rhesus monkeys with spinal cord injuries. The grafts not only survived, but grew hundreds of thousands of human axons and synapses, resulting in improved forelimb function in the monkeys.
Northwestern University researchers have developed a new “smell virtual landscape” that enables the study of how smells engage the brain’s navigation system. The work demonstrates, for the first time, that the mammalian brain can form a map of its surroundings based solely on smells. The olfactory-based virtual reality system could lead to a fuller understanding of odor-guided navigation and explain why mammals have an aversion to unpleasant odors, an attraction to pheromones and an innate preference to one odor over another.
A special receptor on cells that line the sinuses, throat and lungs evolved to protect mammals from developing a range of allergies and asthma, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.

Does life really begin at 40? Is 50 the new 30? For people in these age groups, the answer appears to be yes. But for young adults in their teens and early 20s, turning 50 equates to hitting old age. A new study of more than a half-million Americans led by a Michigan State University scholar shows just how skewed views of aging can be - particularly among the young.
In two recent publications, teams of researchers led by Penn State provide new understanding of why synthetic two-dimensional materials often perform orders of magnitude worse than predicted, and how to improve their performance in future electronics, photonics, and memory storage applications.
Researchers have developed a method that will help natural gas experts better understand shale samples and eventually help them decide whether to invest time and resources to extract gas from the formation the samples came from.
More than 70 percent of the global King penguin population, currently forming colonies in Crozet, Kerguelen and Marion sub-Antarctic islands, may be nothing more than a memory in a matter of decades, as global warming will soon force the birds to move south, or disappear. This is the conclusion of a study published in the current issue of the prestigious journal Nature Climate Change and performed by an international team of researchers from France, Monaco, Italy, Norway, South Africa, Austria and US.
Most election polls take the political pulse of a state or nation by reaching out to citizens about their voting plans. Santa Fe Institute Professor Mirta Galesic says pollsters might also ask: how do your friends plan to vote?
