Researchers from the University of Texas at Austin have discovered that soil microbes from historically wetter sites are more sensitive to moisture and emit significantly more carbon than microbes from historically drier regions. The findings, reported today in the Proceedings of the National Academy of Sciences, point the way toward more accurate climate modeling and improve scientists' understanding of distinct regional differences in microbial life.
Engineers at the University of California, Riverside have developed a new way to recover almost 100 percent of the water from highly concentrated salt solutions. The system will alleviate water shortages in arid regions and reduce concerns surrounding high salinity brine disposal, such as hydraulic fracturing waste.
Researchers report that CRISPR-Cas9 gene-editing technology can introduce hundreds of unintended mutations into the genome.
Scientists at The Scripps Research Institute (TSRI) have given new superpowers to a lifesaving antibiotic called vancomycin, an advance that could eliminate the threat of antibiotic-resistant infections for years to come.
A University of Utah-led team has discovered that a class of 'miracle materials"'called organic-inorganic hybrid perovskites could be a game changer for future spintronic devices that use the direction of the electron spin -- either up or down -- to carry information in 1s and 0s. The researchers discovered that the perovskites possess two contradictory properties necessary to make spintronic devices work.
A team at the Wyss Institute of Biologically Inspired Engineering led by Pamela Silver, Ph.D., designed a powerful bacterial sensor with a stable gene circuit in a colonizing bacterial strain that can record gut inflammation for six months in mice. This study offers a solution to previous challenges associated with living diagnostics and may bring them closer to use in human patients. The findings are reported in Nature Biotechnology.
Overheated cities face climate change costs at least twice as big as the rest of the world because of the 'urban heat island' effect, new research shows.
In the Neotropics, there is a whole group of so-called glassfrogs that amaze with their transparent skin covering their bellies and showing their organs underneath. A recently discovered new species from Amazonian Ecuador, however, goes a step further to fully expose its heart thanks to the transparent skin stretching all over its chest as well as tummy. The new amphibian is described in the open-access journal ZooKeys.
The study found that only 26.6% and 21.3% of sufferers were achieving the current recommended intake of calcium and vitamin D respectively. Achieving the correct levels of calcium and vitamin D is essential for developing children, especially for IBD sufferers, as these nutrients play a vital role in bone health and anti-inflammatory treatments.
ANRS 12286 MOBIDIP, a clinical trial running in parallel in three countries in sub-Saharan Africa, shows that dual therapy with lamivudine and a boosted protease inhibitor is effective as second-line treatment in patients infected by HIV with multiple mutations. Such treatment deescalation will reduce costs, side effects, and the need for virological monitoring of patients. The results of this study are published in The Lancet HIV.
