WEST LAFAYETTE, Ind - Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities.
Genetics may predispose some people to both Alzheimer's disease and high levels of blood lipids such as cholesterol, a common feature of cardiovascular disease, according to a new study by an international team of researchers led by scientists at UC San Francisco and Washington University School of Medicine in St. Louis.
Researchers at The University of Texas at Arlington have found a potential new pathway to regulate immune response and potentially control inflammatory diseases of the central nervous system such as meningitis and sepsis.
"We need to know what turns on inflammatory response to bacterial infection to be able to modulate the process," said Subhrangsu Mandal, the UTA associate professor of chemistry who led the research.
UNIVERSITY PARK, Pa. -- Helping residents become more physically fit may not just be a walk in a park, it could also be a walk to a park, according to a team of Penn State researchers.
In a study, the researchers found that small improvements to a city's ParkScore - an evaluation of a city's park system -- could lead to more physical exercise for its residents. The Trust for Public Land created the ParkScore as an index to rank the park systems of the nation's largest 100 cities, they added.
MINNEAPOLIS - Researchers have been searching for possible treatments for the polio-like illness causing paralysis in children, called acute flaccid myelitis. But a new study shows no signal of efficacy for one potential treatment, the antidepressant fluoxetine. The study is published in the November 9, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
UNIVERSITY PARK, Pa. -- Mosquitoes of the genus Anopheles are well known as primary vectors of malaria. But a new study suggests that Anopheles species, including some found in the United States, also are capable of carrying and transmitting an emerging pathogen, Mayaro virus, which has caused outbreaks of disease in South America and the Caribbean.
AMHERST, Mass. - A major factor holding back development of wearable biosensors for health monitoring is the lack of a lightweight, long-lasting power supply. Now scientists at the University of Massachusetts Amherst led by materials chemist Trisha L. Andrew report that they have developed a method for making a charge-storing system that is easily integrated into clothing for "embroidering a charge-storing pattern onto any garment."
AMHERST, Mass. - A new predictive model developed by an ecologist at the University of Massachusetts Amherst and a climate scientist at the University of Washington suggests that climate change may allow common ragweed to extend its growing range northward and into major northeast metro areas, worsening conditions for millions of people with hay fever and asthma.
Nov. 9, 2018--Babies with cystic fibrosis may breathe better by inhaling hypertonic saline, according to a randomized controlled trial conducted in Germany and published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
Drawing from almost 200 scientific studies on workplace meetings, a team of psychological scientists provides recommendations for making the most out of meetings before they start, as they're happening, and after they've concluded.
Potatoes, native to South America, became an agricultural crop thousands of years ago in the Andean highlands of Peru. And just as the ancient Andean people turned wild tubers into the domesticated potato, the potato may have altered the genomes of the Andeans who made it a staple of their diet.
Science Advances published the findings. DNA analyses show that ancient populations of the Peruvian highlands adapted to the introduction of agriculture and an extreme, high-altitude environment in ways distinct from other global populations.
Repetition is the best method for memorization, for neurons themselves. This is the principle behind what neurobiologists call sequence reactivations: during sleep, neurons in the hippocampus related to a task activate very quickly in turn in a precise order, which consolidates the memory of this task. Sequence reactivations are fundamental for long-term memorization and for exchanges between the hippocampus and the rest of the brain. These are only present at rest so they appear after initial neuron activity, which implies that they "memorize" the order they should turn on in.
Globally, pneumonia and diarrhea together led to nearly one of every four deaths that occurred in children under five years of age in 2016. The 2018 Pneumonia and Diarrhea Progress Report--released ahead of the 10th annual World Pneumonia Day, on November 12, by the International Vaccine Access Center (IVAC) at the Johns Hopkins Bloomberg School of Public Health--describes efforts to fight pneumonia and diarrhea in 15 countries with the greatest number of deaths from these illnesses.
Because of their antimicrobial and antifungal properties, silver nanoparticles measuring between one and 100 nanometers (billionth of a meter) in size, are being incorporated outside the United States into a variety of kitchen products known as food contact materials (FCMs). Among the nanosilver-infused FCMs now on the market overseas are spatulas, baby mugs, storage containers and cutting boards. However, the use of these items raises concerns that the nanoparticles in them will migrate into foods and the environment, and in turn, whether this poses risks to human health.
A geology professor at the University of Nevada, Las Vegas, has discovered that a set of 28 footprints left behind by a reptile-like creature 310 million years ago, are the oldest ever to be found in Grand Canyon National Park.
The fossil trackway covers a fallen boulder that now rests along the Bright Angel Trail in the national park. Rowland presented his findings at the recent annual meeting of the Society of Vertebrate Paleontology.
