A mathematical approach for studying local magnetic interactions has helped scientists understand the magnetic properties of a material with long-range magnetic order.
ECDC has updated its rapid risk assessment on the Zika epidemic that continues to evolve in the Americas and the Caribbean.
Policy makers must harness the power of ordinary people if society is to transition to a low-carbon energy future, argues a leading technology historian.
A breakthrough could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defense and other areas using sensing devices for night vision, and boosting applications to a host of new areas, including agriculture. Researchers have demonstrated a dramatic increase in the absorption efficiency of light in a layer of semiconductor only a few hundred atoms thick -- from 7.7 percent currently to almost 99 percent light absorption.
Our romantic choices are not just based on feelings and emotions, but how rich we feel compared to others, a new study has found.
Growing tissues and organs in the lab for transplantation into patients could become easier after scientists discovered an effective way to produce three-dimensional networks of blood vessels, vital for tissue survival yet a current stumbling block in regenerative medicine.
Recognizing that the use of biomarkers has led to advances in the detection of Alzheimer's disease (AD), researchers reviewed a PET amyloid imaging agent, finding that imaging with PiB provides early detection of disease and allows clinicians to distinguish AD from other dementias. Using this and other agents provides a valuable pathway for investigating the relationship between amyloid pathology and changes in cognition, brain structure, and function.
A new molecular mechanism has been discovered that can be used to inhibit the growth of hepatocellular carcinoma, which is the most common liver cancer, report scientists.
A report commissioned by the United Nations offers a glimmer of hope to those managing the impact of bleaching on the world's coral reefs, including the Great Barrier Reef. The 35 authors of the United Nations Environmental Programme in-depth report say as the world's surface reefs are being threatened, part of the ecosystem may survive in these barely known deeper environments, known as mesophotic coral ecosystems (MCEs).
Higher salt intake may increase risk of cardiovascular disease among patients with chronic kidney disease
Scientists have evaluated more than 3,500 participants with chronic kidney disease, examining the association between urinary sodium excretion and clinical cardiovascular disease (CVD) events.
Urban neighborhoods in Ontario, Canada, that were characterized by more walkable design were associated with decreased prevalence of overweight and obesity and decreased incidence of diabetes between 2001 and 2012, according to a study.
Researchers analyzed treatment indications for antidepressants and assessed trends in antidepressant prescribing for depression.
Researchers are shedding light on the early chemical reactions in the organic sediments that would ultimately become the Marcellus Shale, a major source of natural gas and petroleum.
Scientists report that they have found evidence of hardy, methane-producing microbes in water that surfaces from deep underground at The Cedars, a set of freshwater springs in Sonoma County.
First-ever CT scans of the early armored dinosaur Pawpawsaurus campbelli reveal that although the Texas dino lacked its cousin's club-tail it had a sharp nose for danger. A relative of Ankylosaurus, Pawpawsaurus's saving grace from predators may have been an acute sense of smell, says vertebrate paleontologists. Pawpawsaurus lived 100 million years ago, preceding Ankylosaurus by 35 million years. CT scans allow scientists to determine how the animal's brain functioned.
Feeding at the breast may be healthier than feeding pumped milk from a bottle for reducing the risk of ear infection, and feeding breast milk compared with formula may reduce the risk of diarrhea, according to a recent study.
Astronomers have detected for the first time the most luminous gamma-ray emission from the merging galaxy Arp 220 -- the nearest ultraluminous infrared galaxy to Earth reveals the hidden extreme energetic processes in galaxies. Luminous infrared galaxies and ultraluminous infrared galaxies are the most luminous of all galaxies.
Scientists have discovered a new catalyst that allows the easy conversion of natural gas constituents into precursors for the production of fuels or complex chemicals, such as polymers or pharmaceuticals. The new catalyst is extremely stable and results in fewer unwanted by-products.
Drinking during early to mid-adolescence can lead to vulnerability to chronic stress, according to new research. A research team gave alcohol to rats every other day, starting from early to mid-adolescence. When the team looked at the same rats in adulthood, they found that adult males didn't show hormonal stress adaptation, making them more vulnerable to chronic stress.
Parents struggling to find and afford therapy for their child with autism may eventually be able to provide that therapy themselves with the help of telehealth training, a new report suggests.
