AMES, Iowa – Let’s see, thought James Vary, how can we have a little fun with the name of our $1 million nuclear physics project?   Hmm, can we work in the term hack?   So, it’s “Nuclei and Hadrons with Quantum Computers.” Or, “NuHaQ,” for short.   “It’s a takeoff on ‘hack,’” said Vary, an Iowa State University professor of physics and astronomy and leader of a new project supported by a three-year, $1 million grant from the U.S. Department of Energy. In academic computing circles, “to be a good hacker is a positive compliment. Hackers ...

INFORMS Journal Organization Science New Study Key Takeaways: Choosing who to speak to greatly impacts how ideas are heard and implemented in the workplace. Employees who speak to managers or bosses who have the authority and resources to address an issue, led to a 12%-15% increase in implementing ideas and subsequent sales performance. Speaking to peers was associated with a 10% decrease in implemented ideas and subsequent sales performance.   BALTIMORE, MD, February 21, 2023 – Is speaking up at work worth it? New research in the INFORMS journal Organization Science finds that new ideas can be heard and implemented in the office, but it depends on who employees talk to. “There ...

Researchers from the Icahn School of Medicine at Mount Sinai have generated the first induced pluripotent stem cells (iPSCs) from bats, gaining valuable insights into the close relationship between bats and viruses. This research opens the door to studying how viruses like SARS-CoV-2, which causes COVID-19, survive, spread, and evade the immune system through molecular adaptations to new hosts. The team’s findings, published February 21 in Cell, may also shed light on the unique properties of bats that underlie their remarkable defenses against aging and cancer. “Our study suggests that bats have evolved mechanisms to tolerate a large ...

WASHINGTON, Feb. 21, 2023 – It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don’t have access to clean drinking water. As for the pollution of potable and natural water sources, one of the main culprits is arsenic, an abundant and toxic element in the earth’s crust. Arsenic is currently known as the cause of groundwater contamination in more than 100 countries – and can produce life-threatening diseases, especially for populations in developing ...

In 2015, scientists for the first time detected gravitational waves, ripples in space-time that occur when major cosmic events—like the collision and merging of two black holes—disrupt the cosmos. The observation of these waves confirmed Einstein’s theory of general relativity, which predicted such waves would occur if space-time worked as he believed it did. In the seven years since, nearly 100 merging black holes have been detected by observing the gravitational waves that these extraterrestrial events emit. Now, thanks to new research from a team of 14 led by Caltech ...

About The Study: Sustained low-wage earning in midlife may be associated with elevated mortality risk and excess deaths, especially when experienced alongside unstable employment, according to the results of this study including 4,000 workers. If causal, the findings suggest that social and economic policies that improve the financial standing of low-wage workers (e.g., minimum wage laws) could improve mortality outcomes.  Authors: Katrina L. Kezios, Ph.D., of Columbia University in New York, is the corresponding author.

Tokyo, Japan – A retrovirus known as human T-cell lymphotropic virus type 1 (HTLV-1) is known to cause a number of diseases, including inflammatory diseases of the eye. Recently, researchers in Japan have investigated an antibody treatment for inflammatory eye disease in ocular cells infected with HTLV-1.   In a new study published in Frontiers in Immunology, researchers from Tokyo Medical and Dental University (TMDU) evaluated the safety of an anti-VEGF drug, Aflibercept, in a cell culture model exposed to HTLV-1. HTLV-1 infection can cause such diseases as adult T-cell leukemia and HTLV-1 uveitis, an inflammatory eye condition.   Vascular ...

  When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions. Previous studies of black hole collisions modeled the behavior of the gravitational waves using what is known as linear math, which means that the gravitational waves rippling outward did not influence, or interact, with each other. Now, a new analysis has modeled the same collisions in more detail and revealed so-called nonlinear ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU).   By measuring the different speeds at which these waves penetrate and pass through the Earth’s inner core, the researchers believe they’ve documented evidence of a distinct layer inside Earth known as the innermost inner core -- a solid “metallic ball” that sits within the centre of the inner core.  Not long ago it was thought Earth’s structure was comprised of four distinct layers: the crust, the mantle, the outer core and the inner core. The ...

In a bid to understand why mosquitoes may be more attracted to one human than another, Johns Hopkins Medicine researchers say they have mapped specialized receptors on the insects’ nerve cells that are able to fine-tune their ability to detect particularly “welcoming” odors in human skin. Receptors on mosquito neurons have an important role in the insects’ ability to identify people who present an attractive source of a blood meal, according to Christopher Potter, Ph.D., associate professor of neuroscience at the Johns Hopkins University School of Medicine. “Understanding ...

Woods Hole, Mass. (Feb. 21, 2023) -- When the Covid-19 pandemic hit in 2020 with associated travel restrictions, Matthew Long thought his students could shift their overseas research projects to instead study the seagrass meadow ecosystem in Waquoit Bay. It’s a shallow, micro-tidal estuary on the south side of Cape Cod in Massachusetts, near the Woods Hole Oceanographic Institution (WHOI) where Long is an associate scientist in the Marine Chemistry and Geochemistry Department. However, when Long and his students looked for seagrass meadows where he had seen them in previous years, there were only a few shoots of dying Zostera marina eelgrass, ...

Bethesda, MD (Feb. 21, 2023) — In new evidence-based guidelines, the American Gastroenterological Association (AGA) recommends non-invasive biomarkers as a first-line strategy for monitoring many patients with ulcerative colitis (UC). These guidelines were published today in Gastroenterology. The AGA guidelines outline use cases for three biomarkers that provide accurate insights into ulcerative colitis disease activity: serum C-reactive protein (CRP) (blood), fecal calprotectin (stool) and fecal lactoferrin (stool). “For decades we have regarded endoscopy as the gold ...
