RESEARCH TRIANGLE PARK, N.C. -- Army-funded researchers discovered how to make materials capable of self-propulsion, allowing materials to move without motors or hands.
Researchers at the University of Massachusetts Amherst discovered how to make materials that snap and reset themselves, only relying upon energy flow from their environment. This research, published in Nature Materials and funded by the U.S. Army, could enable future military robots to move from their own energy.
WASHINGTON -- In a new study, investigators report an optimized approach to using laser-induced breakdown spectroscopy (LIBS) for analyzing hydrogen isotopes. Their new findings could enable improved rapid identification and measurement of hydrogen and other light isotopes that are important in nuclear reactor materials and other applications.
People who are unable to make their rent or mortgage payments sleep less than than their peers who don't have such problems, and those who are forced to move because of financial problems sleep even less, according to a new RAND Corporation study.
The study, which followed 1,046 people receiving welfare in California over several years, is the first to analyze the relationship between housing insecurity and sleep outcomes after controlling for sleep duration and sleep quality measured prior to experiences with housing insecurity.
Richard Feynman, one of the most respected physicists of the twentieth century, said "What I cannot create, I do not understand". Not surprisingly, many physicists and mathematicians have observed fundamental biological processes with the aim of precisely identifying the minimum ingredients that could generate them. One such example are the patterns of nature observed by Alan Turing.
ITHACA, NY - When it comes to saving endangered species of a certain size, conservationists often have to think outside the box.
This was reinforced by a recent study published in the Journal of Wildlife Diseases, led by faculty in the College of Veterinary Medicine, which analyzed the effects of hanging tranquilized black rhinoceroses upside down by their feet.
"We found that suspending rhinos by their feet is safer than we thought," said Dr. Robin Radcliffe, senior lecturer in wildlife and conservation medicine and first author of the study.
How to study the stages children go through as they play together has been highlighted in new research by a Swansea University academic.
Play is a crucial part of a child's development. It is how children develop cognitive skills and learn new information as well as social skills and it is an important topic of research by social scientists.
CLEVELAND - Evidence suggests particulate matter is the air pollutant which poses the greatest threat to global health. Studies have shown that exposure to particulate matter smaller than 2.5 microns is associated with acute and chronic elevations in blood pressure (BP) as well as hypertension.
Las Vegas, Nev. (Monday, Feb. 1, 2021) - In the summer of 2019, Desert Research Institute (DRI) scientist Rosemary Carroll, Ph.D., waited for the arrival of the North American Monsoon, which normally brings a needed dose of summer moisture to the area where she lives in Crested Butte, Colo. - but for the fourth year in a row, the rains never really came.
Oak Brook, IL - The February edition of SLAS Technology is a special collection of articles focused on "Artificial Intelligence in Process Automation" by Guest Editor Cenk Ündey, Ph.D. (Amgen, Thousand Oaks, CA, USA).
Hydrocarbons and petroleum are almost synonymous in environmental science. After all, oil reserves account for nearly all the hydrocarbons we encounter. But the few hydrocarbons that trace their origin to biological sources may play a larger ecological role than scientists originally suspected.
A team of researchers at UC Santa Barbara and Woods Hole Oceanographic Institution investigated this previously neglected area of oceanography for signs of an overlooked global cycle. They also tested how its existence might impact the ocean's response to oil spills.
In the United States only about 1.3 percent of all vehicles sold last year were battery powered. And about 90 percent of those sales were by one company -- Tesla. What has Tesla done right and where have other electric vehicle makers gone wrong?
CHARLOTTESVILLE, VA (FEBRUARY 2, 2021). Researchers in the United Kingdom (UK) conducted a randomized controlled trial in 47 patients with lumbar spinal stenosis to compare treatment outcomes and costs of two competing surgical procedures: insertion of the X-Stop® (Medtronic) interspinous distractor device and open decompression surgery with laminectomy. Both procedures improved the patients' quality of life; however, overall, laminectomy gave patients a better quality of life and was also more cost-effective.
A new method for constructing special solar cells could significantly increase their efficiency. Not only are the cells made up of thin layers, they also consist of specifically arranged nanoblocks. This has been shown in a new study by an international research team led by the Martin Luther University Halle-Wittenberg (MLU), which was published in the scientific journal Nano Letters.
Toronto, ON - Results of a multi-centre, international, clinical trial co-led by Peter Munk Cardiac Centre (PMCC) cardiologist Dr. Dinesh Thavendiranathan point to the benefit of using a more sensitive test to detect heart function issues early, so cancer patients don't have to fight heart failure too.
Scientists at The Marine Mammal Center - the world's largest marine mammal hospital - have found that viral-caused cancer in adult California sea lions is significantly increased by their exposure to toxins in the environment. The study is the result of over 20 years of research and examination of nearly 400 California sea lion patients by The Marine Mammal Center.
