The particles, discovered in mice, may activate immune function and could play a role in preventing metabolic disorders — ScienceDaily

Researchers have discovered that fat tissue releases a lipid-filled particle that has a role in immune function and metabolism. The study, in mice, was published online in the journal Science. Why it matters Obesity appears to activate the immune system, contributing to type 2 diabetes, nonalcoholic fatty liver disease, and other disorders. Understanding how fat…

Could medical marijuana help older people with their ailments?

Medical marijuana may bring relief to older people who have symptoms like pain, sleep disorders or anxiety due to chronic conditions including amyotrophic lateral sclerosis, Parkinson’s disease, neuropathy, spinal cord damage and multiple sclerosis, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 71st Annual Meeting in…

Genetic test to detect antimicrobial resistance developed — ScienceDaily

Researchers at American University have developed a new, highly sensitive rapid genetic test that can determine whether bacteria carries a gene that causes resistance to two common antibiotics used to treat strep throat and other respiratory illnesses. The scientists show that the new method works as accurately as culture-based methods but gives results in minutes,…

Using stardust grains, scientists build new model for nova eruptions — ScienceDaily

What do tiny specks of silicon carbide stardust, found in meteorites and older than the solar system, have in common with pairs of aging stars prone to eruptions? A collaboration between two Arizona State University scientists — cosmochemist Maitrayee Bose and astrophysicist Sumner Starrfield, both of ASU’s School of Earth and Space Exploration — has…

Study could lead to better strategies for protecting crops from attacks by pathogens — ScienceDaily

A team led by a plant pathologist at the University of California, Riverside, has identified a regulatory, genetic mechanism in plants that could help fight bacterial infection. “By better understanding this molecular mechanism of regulation, we can modify or treat crops to induce their immune response against bacterial pathogens,” said Hailing Jin, a professor of…

Study uses automated models to identify sepsis before clinical recognition — ScienceDaily

Automated programs can identify which sick infants in a neonatal intensive care unit (NICU) have sepsis hours before clinicians recognize the life-threatening condition. A team of data researchers and physician-scientists tested machine-learning models in a NICU population, drawing only on routinely collected data available in electronic health records (EHRs). “Because early detection and rapid intervention…

Hybrid material may outperform graphene in several applications — ScienceDaily

Materials that are hybrid constructions (combining organic and inorganic precursors) and quasi-two-dimensional (with malleable and highly compactable molecular structures) are on the rise in several technological applications, such as the fabrication of ever-smaller optoelectronic devices. An article published in the journal Physical Review B describes a study in this field resulting from the doctoral research…

Climate change is shifting productivity of fisheries worldwide — ScienceDaily

Fish provide a vital source of protein for over half the world’s population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food. A team of scientists led by Christopher Free, a postdoctoral scholar at UC…

New method of synthesizing nanographene on metal oxide surfaces — ScienceDaily

Nanostructures based on carbon are promising materials for nanoelectronics. However, to be suitable, they would often need to be formed on non-metallic surfaces, which has been a challenge — up to now. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have found a method of forming nanographenes on metal oxide surfaces. Their research, conducted within the framework of…

Drilling results reveal global climate influence on basin waters in young rifts — ScienceDaily

Young rift basins, such as the Gulf of Corinth, are known to be sensitive recorders of past changes in climate and sea level and of the chemical and biological conditions of the waters they contain. Nonetheless, the changes observed in the Gulf of Corinth, published in the journal Nature, were more dramatic and complex than…
