'We first found excitons with charge transfer at the boundary of fundamental adsorption in nickel oxide and at the impurity adsorption edge in magnesium oxide. These results may be of interest to specialists in theoretical physics who study the band structure of oxides with strong correlations. NiO has been considered as prototype of such oxides for a long time, and many calculation schemes have been tested using this object' concludes Anatoly Zatsepin.
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.
Newborn Immune Activation May Have Long-Term Negative Impact on Brain FunctionNewborn immune activation may have long-term negative impact on brain function
McLean neuroscientists have found that even a brief episode of immune system activation within days of birth can cause persistent changes in sleep patterns concurrent with increases in epilepsy-like brain activity -- a combination of symptoms common in autism spectrum disorder (ASD) and other developmental conditions.
Canola and other edible oils are easily affected by light irradiation or heat treatment. Since such processes deteriorate the oil quality such as flavor or taste, understanding this process, called oxidation, is imperative to identify effective measures to control the oil quality such as the best way to package or store oil.
Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research published in Nature Communications is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.
In the Jan. 12, 2018, Scientific Reports, a research team describes early tests of a minimally-invasive way to assess myelin damage -- the hallmark of multiple sclerosis -- using positron emission tomography (PET). This approach could be used to follow MS lesions over time.
Scientists at the CNIC and Columbia University have identified a new mechanism regulating the elasticity of titin, a protein with important roles in the function of skeletal and heart muscle.
Women who consume Internet pornography are using technology to explore their sexuality and connect with others to discuss their sexual interests, according to research from the University of Waterloo.
A new study suggests an association between elevated amyloid beta levels & the worsening of anxiety symptoms. The findings support the hypothesis that neuropsychiatric symptoms could represent the early manifestation of Alzheimer's disease in older adults.
Asthma costs the US economy more than $80 billion annually in medical expenses, missed work and school days and deaths, according to new research published online in the Annals of the American Thoracic Society.
Among older patients, frailty and cognitive impairment before surgery are associated with developing complications after surgery, but age is not, a new study suggests.
A study published in Military Medicine showed that after 30 days of practicing the Transcendental Meditation technique, 80 percent of the 46 veterans and active-duty personnel no longer had PTSD. All participants had been clinically diagnosed with PTSD using a standard assessment. By comparison, standard treatments for PTSD--prolonged exposure therapy, cognitive processing therapy, and medication--are only partially successful: approximately two-thirds of patients receiving cognitive processing therapy or prolonged exposure still have PTSD after treatment.
Microscopic yeast have been wreaking havoc in hospitals around the world -- creeping into catheters, ventilator tubes, and IV lines -- and causing deadly invasive infection. One culprit species, Candida auris, is resistant to many antifungals, meaning once a person is infected, there are limited treatment options. But in a recent Antimicrobial Agents and Chemotherapy study, researchers confirmed a new drug compound kills drug-resistant C. auris, both in the laboratory and in a mouse model that mimics human infection.
Secondary aerosol formation and rapid increases in aerosol particle sizes are believed to play important roles in haze formation. However, some simple but important questions remain unanswered, such as: How frequently and how fast do fine aerosol particles grow? And what affects their rates of growth?
When older adults arrive at a hospital's emergency department, they may face unexpected challenges. To address these challenges, geriatrics experts have developed special programs such as the "Geriatric Emergency Department Innovations in Care through Workforce, Informatics, and Structural Enhancements" (GEDI WISE) program.
Scientists from Caltech have developed a technology that allows them to see which neurons are talking to which other neurons in live fruit flies.
New research by MDI Biological Laboratory scientist Sandra Rieger, Ph.D., has demonstrated that an enzyme she had previously identified as playing a role in peripheral neuropathy induced by cancer chemotherapy also plays a role in peripheral neuropathy caused by diabetes. The significance of the identification of a common molecular mechanism is that the drug candidates she identified to treat chemotherapy-induced peripheral neuropathy could potentially be used to treat peripheral neuropathy caused by diabetes as well.
Water-saving measures in California have also led to substantial reductions in greenhouse gas (GHG) emissions and electricity consumption in the state.That is the conclusion of new research from the University of California, Davis, published today in the journal Environmental Research Letters.
Satisfaction with care in hospitals declines when patients believe there are not enough nurses on wards, according to a new study based on the NHS Inpatient Survey published in the BMJ Open.
In the Vet Record today, a team of researchers based in The Netherlands say these diets may be contaminated with bacteria and parasites, and as such may pose a risk to both animal and human health.
