HANOVER, N.H. - Nov. 13, 2017 - A set of fundamental tactics ranging from the theoretical to the practical can be used to combat the challenges brought on by pests in rapidly changing forests, according to a research paper from Dartmouth College and the University of Santiago de Compostela.

With forests under pressure worldwide due to human activities in what is now often referred to as the Anthropocene era, the researchers analyzed why forests around the world are being impacted by new pests and what can be done about it.

WASHINGTON, DC -- Military service exposes soldiers to a unique set of physical challenges, including toxic chemicals and traumatic brain injury, which can have profound effects on their health and well-being. New research examines the effects of military-related brain disorders and possible paths toward treatment, as well as a potential way to harness our brain's learning capabilities to better train pilots.

New York, NY (November 10, 2017) - Researchers at Columbia University Medical Center (CUMC) and the New York State Psychiatric Institute (NYSPI) may have discovered a way to use a patient's sense of smell to treat Alzheimer's disease before it ever develops. Having an impaired sense of smell is recognized as one of the early signs of cognitive decline, before the clinical onset of Alzheimer's disease.

Researchers from the Physics Department of Moscow State University and their colleagues have discovered a mechanism that allows gas sensors, based on nanocrystalline metal oxides, to work at room temperature. This invention will raise the efficiency of environmental monitoring at nuclear power plants, on submarines and spacecrafts. The discovery was reported in Scientific Reports.

Until recently, it was assumed that the ink used for writing was primarily carbon-based at least until the fourth and fifth centuries AD. But in a new University of Copenhagen study, analyses of 2,000-year-old papyri fragments with X-ray microscopy show that black ink used by Egyptian scribes also contained copper - an element previously not identified in ancient ink.

Lasers that generate plasma can provide insight into bursts of subatomic particles that occur in deep space, scientists have found. Such findings could help scientists understand cosmic rays, solar flares and solar eruptions -- emissions from the sun that can disrupt cell phone service and knock out power grids on Earth.

LIVERMORE, Calif. -- A Sandia National Laboratories-led team has demonstrated faster, more efficient ways to turn discarded plant matter into chemicals worth billions. The team's findings could help transform the economics of making fuels and other products from domestically grown renewable sources.

The article, titled "Tablet-based cross-curricular Maths vs. traditional Maths classroom practice for higher-order learning outcomes", was published in Computers and Education.

About 300 seven-year-old children from 12 Slovenian schools took part in the research which lasted for 7 months. Accessibility of applications on the basis of cross-curricular modules was examined with regard to learning and ergonomics.

"We investigated how performance of cross-curricular tasks on tablet computers influenced the boost in quality of knowledge", Dr. Starcic specified.

New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fate.

More than one-third of Americans are considered obese based on their Body Mass Index (BMI). BMI measures the ratio between your height and weight. A BMI of 30 or above signals obesity. As more and more of us age, we also are likely to see an increase in the number of older people who have a difficult time maintaining a healthy body weight. That's a serious problem, since obesity can impact many parts of our health and daily life.
