Scientists have developed a three-dimensional imaging technique to observe complex behaviours in magnets, including fast-moving waves and 'tornadoes' thousands of times thinner than a human hair.
You can't see them, but most of the metals around you--coins, silverware, even the steel beams holding up buildings and overpasses--are made up of tiny metal grains. Under a powerful enough microscope, you can see interlocking crystals that look like a granite countertop.
New data gleaned from the magnetic sensor aboard NASA's InSight spacecraft is offering an unprecedented close-up of magnetic fields on Mars.
In a study published today in Nature Geoscience, scientists reveal that the magnetic field at the InSight landing site is ten times stronger than anticipated, and fluctuates over time-scales of seconds to days.
Researchers in South Korea have developed a new optical communications technology that can transfer data in lightning speed. The new technology sends and receives twice as much data than conventional methods. It is expected to contribute to solving data traffic congestion in 5G networks.
Researchers from the Spanish National Cancer Research Centre (CNIO), Madrid, and the Andalusian Molecular Biology and Regenerative Medicine Centre (Cabimer), Seville, published today a paper in Nature Communications that shows that DNA topological problems may cause endogenous DNA breaks that have a causal relationship with cancer.
Researchers led by Profs. LI Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences recently developed a composite membrane for long-life zinc-based flow batteries. Their study was published in Angewandte Chemie International Edition.
A new study led from the University of Southampton has shown that threatened birds and mammals are often ecologically distinct and irreplaceable in their environment.
Scientists at Tokyo Institute of Technology (Tokyo Tech) have shown that single platinum atoms trapped in C12A7 crystals act as a stable and effective catalyst for the hydrogenation of nitroarenes, an essential process in the production of many kinds of fine chemicals. Their approach could become a versatile route for developing other single-atom catalysts for wide-ranging industrial applications.
Modern anticancer therapies aim to attack tumor cells while sparing healthy tissue. An interdisciplinary team of researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and FU Berlin has made important progress in this area: the scientists have produced tiny nanoparticles that are designed to specifically target cancer cells. They can navigate directly to the tumor cells and visualize those using advanced imaging techniques. Both in petri dishes and animal models, the scientists were able to effectively guide the nanoparticles to the cancer cells.
CHAMPAIGN, Ill. -- Komorebi is a Japanese word that describes how light filters through leaves--creating shifting, dappled "sunflecks" that illustrate plants' ever-changing light environment. Crops harness light energy to fix carbon dioxide into food via photosynthesis.
SILVER SPRING, Md.--Intensive behavioral therapy (IBT) combined with liraglutide 3.0 mg (Saxenda) can produce clinically-meaningful weight loss in patients who receive the treatment in predominantly primary care settings, according to a study published online in Obesity, the flagship journal of The Obesity Society. The study is the first multi-site evaluation of the efficacy of IBT based on a treatment visit schedule covered by the Centers for Medicare and Medicaid Services (CMS).
DALLAS, Feb. 24, 2020 - Researchers have identified a distinct collection of bacteria found in the gut that may contribute to and predict the development of pulmonary arterial hypertension (PAH), according to new research published today in the American Heart Association's journal Hypertension.
Native fish discovered with spinal deformities in California's Sacramento-San Joaquin Delta in 2011 were exposed to high levels of selenium from their parents and food they ate as juveniles in the San Joaquin River, new research has found.
Wilmington, DE, February 24, 2020 -- While radiation is successfully used to treat breast cancer by killing cancer cells, inflammation caused as a side-effect of radiation can have a contrary effect by promoting the survival of triple-negative breast cancer cells, according to research published online in the International Journal of Radiation Biology by Jennifer Sims-Mourtada, Ph.D., director of Translational Breast Cancer Research at ChristianaCare's Helen F.
It's a problem plaguing grape-growers worldwide--in an ever-changing climate, how can they protect their crops from the undesirable effects of wildfire smoke exposure.
A recent study by a team of UBC Okanagan researchers has led to the development of a preventative strategy for protecting grapes from volatile phenols--flavoured compounds present in smoke that may be absorbed into ripening grapes and subsequently impact wine flavour.
