Researchers turn to quantum computing power to simulate, study atomic nuclei
2023-02-21
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 ...

Enhanced arsenic detection in water, food, soil
2023-02-21
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 ...
A new model to better understand what’s inside colliding black holes
2023-02-21
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 ...
History of low hourly wage and all-cause mortality among middle-age workers
2023-02-21
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.

Physicists create new model of ringing black holes
2023-02-21
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 ...
Bouncing seismic waves reveal distinct layer in Earth's inner core
2023-02-21
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 ...

Excess nutrients lead to dramatic ecosystem changes in Cape Cod’s Waquoit Bay; the bay is a harbinger for estuaries worldwide, say researchers
2023-02-21
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, ...
