New insight on how a butterfly species developed the ability to adjust its wing eyespot size in response to temperature has been published today in eLife.
An innovative manufacturing technique developed by KAUST researchers has led to the development of hybrid organic transistors for use in next-generation electronic displays and large-area electronics.
Thin-film transistors (TFTs) made from metal oxides have useful properties, including optical transparency and high charge-carrying capacity, and they are increasingly being used in organic light-emitting diode displays.
Polymers are long molecules made from periodically connected molecular building blocks called monomers. Some polymers occur naturally in the shape of closed rings - for example as plasmids, cyclic DNA strands in bacteria, or for sufficiently long protein chains. Imagine immersing such objects into a solvent constrained between two parallel plates. We talk about shearing the system when we pull these plates in anti-parallel directions.
University of Bayreuth researchers, together with scientists from Italy and China, have for the first time systematically investigated under which conditions, and to what extent, sulphur-containing arsenic compounds are formed in rice-growing soils. To date, these thioarsenates have not been taken into account in assessments of the health effects of rice consumption. In the journal Nature Geoscience the scientists present their results and identify the urgent need for research with a view to protecting consumers from health risks.
A new measuring method for thioarsenates
New Rochelle, NY, February 11, 2020--A new study evaluated the feasibility and acceptability of using T'ai Chi to improve chronic low back pain in adults over 65 years of age compared to health education and usual care. The results of this randomized controlled trial are published in JACM, the Journal of Alternative and Complementary Medicine, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers, dedicated to paradigm, practice, and policy advancing integrative health.
NASA's Terra satellite passed over the South Pacific Ocean and found a stronger Tropical Cyclone Uesi after obtaining infrared imagery of the storm. Uesi continues moving away from Vanuatu and today is affecting New Caledonia.
More frequent and intense rainfall events due to climate change could cause more landslides in the High Mountain Asia region of China, Tibet and Nepal, according to the first quantitative study of the link between precipitation and landslides in the region.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
Patients with lupus who take their medications as prescribed have much lower odds of developing type 2 diabetes, a common complication of the disease, finds a new study from the University of British Columbia.
In particular, those who consistently took antimalarial drugs like hydroxychloroquine had a 39 per cent lower risk compared to those who were less consistent.
Macrophages are part of the innate immune system and essential for brain development and function. Using a novel method, scientists from Jena University Hospital, the University of Bonn and the Memorial Sloan Kettering Cancer Center in New York (USA) succeeded in visualizing macrophages that were formed in the bone marrow. In studies on mice, this technology enabled the researchers to observe that shortly after a stroke, numerous macrophages that had migrated from the blood begin to attack dead and adjacent healthy brain tissue.
