Osaka, Japan - A team led by Osaka University used angle-resolved photoelectron spectroscopy to probe the unusual surface conductivity of samarium hexaboride crystals. They showed that the material is a co-existing phase of "topological insulator" in which electrical current can flow along the surface but not through the bulk of the sample, a "Kondo insulator", which undergoes a metal-to-insulator transition due to the strong electron correlation.
Oakland, Calif. - Children who receive the chickenpox (varicella) vaccine are significantly less likely to contract shingles, according to a new study led by researchers at the Kaiser Permanente Center for Health Research published today in the journal Pediatrics.
Baltimore (June 9, 2019) - The foods we eat can play an important role in preventing cancer. New modeling research presented at Nutrition 2019 shows that policies using taxes or warning labels to encourage healthier eating could reduce the number of people who develop cancer, which would bring significant savings in medical costs.
An international research team led by the University of Liverpool has made a discovery that will help with the search for electric dipole moments (EDM) in atoms, and could contribute to new theories of particle physics such as supersymmetry.
Short lived isotopes of both radon and radium have both been identified as potential candidates for measuring EDM in atoms.
Sediment stirred up from fishing activity has a negative effect on reef-building sea sponges in northern British Columbia, according to a new study by University of Alberta biologists.
The sediment is kicked up during human activities such as bottom trawling, where a weighted net is dragged across the seafloor. It includes organic matter as well as clay and silt, which can smother sponges from the outside or, if taken into their filtration system, can clog them.
Copper and platinum nanoparticles added to the surface of a blue titania photocatalyst significantly improve its ability to recycle atmospheric carbon dioxide into hydrocarbon fuels.
A new way of analysing sperm that tracks the movement of the sperm tail could enable substantial improvements to male fertility testing.
The technique measures the speed and action of the sperm flagellum, or tail, which provides vital information for understanding whether sperm in an ejaculate have the potential to reach and fertilise the egg.
Science professors go through years of training to learn about their field, yet they often don't receive any formal education in how to teach students about it. A new study takes a decade-long look at one way that science departments in the California State University (CSU) system are trying to amend that by bringing faculty with educational expertise into the fold.
Scientists from RIKEN and the University of California San Diego, in collaboration with international partners have found a way to significantly reduce the amount of energy required by organic light emitting diodes (OLEDs). OLEDs have attracted attention as potential replacements for liquid crystal diodes, since they offer advantages such as being flexible, thin, and not requiring backlighting.
The consequences of aging are damage and degeneration of cells, which leads to loss of function, vulnerability to disease, and eventually, death. A hallmark of the aging process is the progressive decline of the nervous system, including both motor and cognitive functions. To complicate matters, natural variation in aging populations makes it difficult to study the factors that contribute to behavioral decline. Because the human aging process is typically slow, elucidating aging biomarkers and predicting individual differences has proven to be very challenging.
DURHAM, N.C. -- Coal ash solids found in sediments collected from Sutton Lake in 2015 and 2018 suggest the eastern North Carolina lake has been contaminated by multiple coal ash spills, most of them apparently unmonitored and unreported until now.
A study conducted by a team of researchers from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore has revealed a close association between liposarcoma (LPS), a type of cancer that develops from fat cells, and the bromodomain and extraterminal (BET) protein family.
A recent, updated predictive analysis of the three WHO-defined molecular subgroups based on isocitrate dehydrogenase 1/2 (IDH) mutation status and 1p/19q co-deletion status represented in the high-risk treatment arms of the NRG Oncology clinical trial NRG-RTOG 9802 indicates that both IDH-mutant sub-groups (IDHmut-noncodel and IDHmut-codel) could benefit from the addition of PCV chemotherapy to radiotherapy treatment.
Thanks to a team of researchers from the University of Illinois at Urbana-Champaign and the University of Massachusetts Amherst, scientists are able to read patterns on long chains of molecules to understand and predict behavior of disordered strands of proteins and polymers. The results could, among other things, pave the way to develop new materials from synthetic polymers.
A new study indicates that racism is toxic to humans.
A team of USC and UCLA scientists found that racist experiences appear to increase inflammation in African American individuals, raising their risk of chronic illness, according to the study published in the journal Psychoneuroendocrinology on April 18.
