CHICAGO, May 11, 2023 – Access to clean drinking water is essential for healthy communities, but delivering that water is growing increasingly difficult for many utilities. Corroding pipes and land shifts in aging water distribution networks can create frequent leaks, wasting water before it ever gets to the tap. Utilities in the U.S. lose about 6 billion gallons of water a day — enough to fill 9,000 swimming pools — due to leaks, in addition to wasted energy and resources spent in collecting and treating that water. Pranav Agrawal and Sriram Narasimhan from the University ...

GRAND RAPIDS, Mich. (May 11, 2023) — Van Andel Institute scientists have pinpointed how a specific gene mutation triggers an inflammatory cascade that may drive development of treatment-resistant cancers. The new findings, published today in Molecular Cell, reveal for the first time the molecular circuitry by which mutations in the gene STK11 cause inflammation to spiral out of control. The resulting chemical firestorm damages healthy cells and can enable cancer development. Tumors that lose the STK11 gene are tough ...

PROVIDENCE, R.I. [Brown University] — For two decades, physicists have tried to directly manipulate the spin of electrons in 2D materials like graphene. Doing so could spark key advances in the burgeoning world of 2D electronics, a field where super-fast, small and flexible electronic devices carry out computations based on quantum mechanics. Standing in the way is that the typical way in which scientists measure the spin of electrons — an essential behavior that gives everything in the physical universe its structure — usually doesn’t work in 2D materials. This makes it incredibly difficult to fully understand the materials and propel forward technological ...

CHICAGO, May 11, 2023 – You may know how other planets look, like the rust orange, dusty surface of Mars or the vibrant teal of Uranus. But what do those planets sound like? Timothy G. Leighton from the University of Southampton in the U.K. designed a software program that produces extraterrestrial environmental sounds and predicts how human voices might change in distant worlds. He will demonstrate his work at the upcoming 184th Meeting of the Acoustical Society of America, running May 8-12 at the Chicago Marriott Downtown Magnificent Mile Hotel. His presentation will take place ...

Answers could be cloudy for researchers using Landsat images to investigate the coverage of the continental United States. The National Land Cover Database (NLCD) are useful products for scientists to understand how things like tree canopy and road coverage changes over time, but something as simple as cloud coverage can be misinterpreted in the satellite images as a significant surface coverage change. How can researchers be sure they’re getting a truly representative understanding of any one area?   The answer lies in composite ...

A common chemical reaction that most people have seen first-hand is the inspiration for a new way to make a flexible gel film that could lead to innovations in sensors, batteries, robotics and more. A research team led by Texas Engineers developed what they call a "dip-and-peel" strategy for simple and rapid fabrication of two-dimensional ionogel membranes. By dipping sustainable biomass materials in certain solvents, molecules naturally respond by arranging themselves into functional thin films at the edge of the material that can easily be removed using nothing more than a simple set ...

Glioblastoma cancer cells use mitochondria from the central nervous system to grow and form more aggressive tumors, according to new Cleveland Clinic-led findings published in Nature Cancer. The research showed that it is common for healthy astrocytes – a type of glial cell with important functions in the central nervous system – to transfer the energy-producing organelles to glioblastoma cancer cells. When this process happens, it makes the cancer more deadly and the tumors more likely to grow. Researchers found that acquiring mitochondria ...

Obstructive sleep apnea associated with increased risks for long COVID Study suggests adults with both the sleep disorder and COVID may benefit from clinical monitoring   Among people who have had COVID-19, adults with obstructive sleep apnea were more likely to experience long-term symptoms suggestive of long COVID than those without the sleep disorder, according to a large study supported by the National Institutes of Health (NIH). In fact, multiple analyses of electronic health records (EHR) identified adults with sleep apnea may have up to a 75% higher risk ...

The senses represent our gates to receive information from the environment, but not all of them are always available for everyone, as in the case of blind or deaf people. Researchers know today quite well that the brain has the critical ability to adapt to different sensory experiences and, in some ways, to “compensate” for the lack of one sense or the other. In a recent study, a group of researchers from the IMT School for Advanced Studies Lucca (Italy), in collaboration with a group from the University of Ulm (Germany), ...
