University at Buffalo research shows 3D printers can be identified by thermodynamic properties, which could could aid intellectual property, security

If you're having trouble sleeping, listening to music can be a safe, effective, and easy way to help you fall and stay asleep. It may also reduce your need for medication to help you sleep.

A team of astronomers including Carnegie's Alycia Weinberger and former-Carnegie postdoc Meredith MacGregor, now an assistant professor at the University of Colorado Boulder, spotted an extreme outburst, or flare, from the Sun's nearest neighbor--the star Proxima Centauri. Their work, which could help guide the search for life beyond our Solar System, is published in The Astrophysical Journal Letters.

"Our results indicate that language ability and domain-general factors were predictive of verbal fluency in individuals with MS," summarized Dr. Chiaravalloti. "Specifically, language ability played a significant role. This could indicate that verbal fluency deficits in MS reflect underlying language impairment," she added, "Our findings further demonstrate the need for more comprehensive examination of language in people with MS."

Women at high risk of breast cancer face cost-associated barriers to care even when they have health insurance, a new study has found. The findings suggest the need for more transparency in pricing of health care and policies to eliminate financial obstacles to catching cancer early.

With Army funding, scientists invented a way to make compostable plastics break down within a few weeks with just heat and water. This advance will potentially solve waste management challenges at forward operating bases and offer additional technological advances for American Soldiers.

On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri--a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun.

Praying mantises are bizarre insects, yet many aspects of their biology remain unknown. Meanwhile, scientists from the Ruhr-University and the Bavarian State Collection of Zoology discovered that females of a South American species protrude a Y-shaped organ on their backs to release pheromones and attract males. Found in none of the over 2,500 species of praying mantises worldwide, the behaviour is reported for the first time in the peer-reviewed scientific Journal of Orthoptera Research.

Piperlongumine, a chemical compound found in the Indian Long Pepper plant, is known to kill cancerous cells in many tumor types. Now an international team including researchers from Penn has illuminated one way in which the piperlongumine works in animal models -- and has confirmed its strong activity against glioblastoma.

A new type of biopsy needle - which vibrates ultrasonically - greatly increases the amount of tissue obtained for pathologists to analyse. Currently, pathologists have to choose between a thick needle that provides a large sample, but causes pain, or a thin needle that is less painful, but gives lower quality samples. The ultrasonic needle solves this by providing large samples with thin needles, which could increase the effectiveness of medical procedures like cancer testing.

Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.

Substantial cuts in global greenhouse gas emissions could be achieved by raising water levels in agricultural peatlands, according to a new study in the journal Nature. A team of researchers led by the UK Centre for Ecology & Hydrology estimates halving drainage depths in these areas could cut emissions by around 500 million tonnes of carbon dioxide (CO2) a year, which equates to 1 per cent of all global greenhouse gas emissions caused by human activities.

Astronomers using data from NASA and the ESA (European Space Agency) telescopes have released a new all-sky map of the outermost region of our galaxy. Known as the galactic halo, this area lies outside the swirling spiral arms that form the Milky Way's recognizable central disk and is sparsely populated with stars. Though the halo may appear mostly empty, it is also predicted to contain a massive reservoir of dark matter.

A study that appeared today on Current Biology sheds new light on the continental migrations which shaped the genetic background of all present Europeans. The research generates new ancient DNA evidence and direct dating from a fragmentary fossil mandible belonging to an individual who lived ~17,000 years ago in northeastern Italy (Riparo Tagliente, Verona).

Scientists at Berkeley Lab and UC Berkeley have designed an enzyme-activated compostable plastic that could diminish microplastics pollution. Household tap water or soil composts break the hybrid plastic material down to reusable small molecules, called monomers, in just a few days or weeks.

A new study by a team including researchers from Lawrence Berkeley National Laboratory and UC Berkeley reports that the social cost of methane - a greenhouse gas that is 30 times as potent as carbon dioxide in its ability to trap heat - varies by as much as an order of magnitude between industrialized and developing regions of the world.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed bistable inflatable structures inspired by origami.

Atherosclerosis -- hardening of the arteries -- is now involved in the majority of deaths worldwide, and advances in our understanding of the biology of the disease are changing traditional views and opening up new avenues for treatment.

The developmental hierarchy of the hypothalamus, which contains an astounding diversity of neurons that regulate endocrine, autonomic and behavioral functions, has not been well understood. Prof. WU Qingfeng's group from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences conducted a study focusing on the origin of this neuronal diversity.

Wildfire smoke can trigger a host of respiratory and cardiovascular symptoms, ranging from runny nose and cough to a potentially life-threatening heart attack or stroke. A new study suggests that the dangers posed by wildfire smoke may also extend to the largest organ in the human body, and our first line of defense against outside threat: the skin.
