INDIANAPOLIS--Researchers from Indiana University have identified key genetic changes in the interstitial kidney tissue of people with diabetes, a discovery that signifies the potential for a revolutionary new genetic approach to the treatment of kidney disease. They will contribute their findings to the Kidney Precision Medicine Project's (KPMP) "cell atlas," a set of maps used to classify and locate different cell types and structures within the kidney.
They shared their groundbreaking findings in a study published on February 10, 2021, in Science Advances.
Researchers from Skoltech and their colleagues have demonstrated that nanoengineered biodegradable microcapsules can guide the development of hippocampal neurons in an in vitro experiment. The microcapsules deliver nerve growth factor, a peptide necessary for neuron growth. The paper describing this work was published in the journal Pharmaceutics.
Scientists from the National Renewable Energy Laboratory (NREL) have developed a simple way to better evaluate the potential of novel materials to store or release heat on demand in your home, office, or other building in a way that more efficiently manages the building's energy use.
How do plants build resilience? An international research team led by the University of Göttingen studied the molecular mechanisms of the plant immune system. They were able to show a connection between a relatively unknown gene and resistance to pathogens. The results of the study were published in the journal The Plant Cell.
The ongoing health disaster of the past 12 months has exposed the crises facing nursing homes in Canada and the United States and the struggles of the staff working in them.
Biologists from RUDN University described the role of tropical rainforests in the production of methane, the second most harmful greenhouse gas after CO2. It turned out that some areas of rainforests not only consumed methane but also emitted it. The results of the study were published in the Forests journal.

Gliomas are common brain tumors that comprise about one third of all cancers of the nervous system. In a study funded by the National Institutes of Health (NIH), researchers tested a novel combination treatment approach on mice with tumors with characteristics similar to human astrocytomas--a type of slow-growing glioma--and found tumor regression in 60 percent of the mice treated. These encouraging results, published in the Journal of Clinical Investigation, could be the first step toward developing a treatment for this type of brain cancer.
As most of us learned in school, plants use sunlight to synthesize carbon dioxide (CO2) and water into carbohydrates in a process called photosynthesis. But nature's "factories" don't just provide us with food -- they also generate insights into how ecosystems will react to a changing climate and carbon-filled atmosphere.
DAVIS, Calif., Feb 16, 2021 - Researchers publishing in the peer-review journal Frontiers in Pediatrics report that pre-term infants fed Bifidobacterium longum subsp. infantis (activated B. infantis EVC001) experienced significantly lower level of intestinal inflammation, 62% less diaper rash, and required 62% fewer antibiotics- all of which are critical health indicators in neonatal care.
Each year an estimated 1.2 million Chinese citizens die prematurely due to poor air quality. And public health consequences are particularly dire during extreme air quality events, such as infamous "Airpocalypse" winter haze episodes.
A team of Northwestern University researchers wondered if widespread adoption of electric vehicles (EVs) could help China avoid these deadly events. The answer? It depends.
Water is a necessity for all life but its availability can be limited. In geographical areas experiencing dry seasons, animals congregate near the few freshwater sources, often reaching large densities. At these sites many animals from different species come to the same spots to drink, potentially operating as key locations for pathogen transmission within and between species. An international team of scientists lead by the German Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) suggests that viruses can use restricted freshwater sources as a vector to be spread among animals.
The effects of microplastics on our health and the environment are being rigorously studied all across the world. Researchers are identifying microplastic sources and their potential routes to the environment by examining rainwater, wastewater, and soil.
Using an advanced technique, scientists from the RIKEN Cluster for Pioneering Research have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface--what we usually call the water surface--than in the bulk of the water, even when the light has equivalent energy. This finding could help our understanding of the many important chemical and biological processes that take place at the water surface.
Milan, 15 February 2021 - Excitons are quasiparticles which can transport energy through solid substances. This makes them important for the development of future materials and devices - but more research is needed to understand their fundamental behaviour and how to manipulate it.
Scientists have discovered that pollution concentration varies between seasons. A new study, conducted in the North China Plain, determined where volatile organic compounds (VOCs) are distributed within the vertical layers of the atmosphere, and found notable changes from winter to summer.
