New molecule found to suppress bacterial antibiotic resistance evolution

Posted by in categories: biotech/medical, chemistry, evolution

Researchers from the University of Oxford have developed a new small molecule that can suppress the evolution of antibiotic resistance in bacteria and make resistant bacteria more susceptible to antibiotics. The paper, “Development of an inhibitor of the mutagenic SOS response that suppresses the evolution of quinolone antibiotic resistance,” has been published in the journal Chemical Science.

About 90% of US adults are on the way to Heart Disease, study suggests

Posted by in categories: biotech/medical, health

Nine of 10 American adults are in the early, middle or late stages of a syndrome that leads to heart disease, a new report finds, and almost 10% have the disease already.

“Poor cardiovascular, kidney, and metabolic health is widespread among the U.S. population,” concludes a team led by Dr. Muthiah Vaduganathan of Brigham and Women’s Hospital and Harvard Medical School in Boston.

Researchers looked specifically at rates of what the American Heart Association has dubbed cardiovascular, kidney and metabolic (CKM) syndrome—interrelated factors that progress with time and, if left unchecked lead to heart disease.

Iron Fingerprints in Nearby Active Galaxy

Posted by in categories: chemistry, cosmology, space travel

After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC4151.

“XRISM’s Resolve instrument captured a detailed spectrum of the area around the black hole,” said Brian Williams, NASA’s project scientist for the mission at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. “The peaks and dips are like chemical fingerprints that can tell us what elements are present and reveal clues about the fate of matter as it nears the black hole.”

XRISM (pronounced “crism”) is led by JAXA (Japan Aerospace Exploration Agency) in collaboration with NASA, along with contributions from ESA (European Space Agency). It launched Sept. 6, 2023. NASA and JAXA developed Resolve, the mission’s microcalorimeter spectrometer.

Physicists Demonstrate Room Temp Quantum Storage in 2D Material

Posted by in categories: particle physics, quantum physics

Microscopic chinks in material just several atoms thick have the potential to advance a multitude of quantum technologies, new research shows – getting us closer to the widespread use of quantum networks and sensors.

Right now, storing quantum data in the spin properties of electrons, known as spin coherence, requires a very particular and delicate laboratory setup. It’s not something you can do without a carefully controlled environment.

Here, an international team of researchers managed to demonstrate observable spin coherence at room temperature, using the tiny defects in a layered 2D material called Hexagonal Boron Nitride (hBN).

Classifying the Surface Magnetization of Antiferromagnets

Posted by in categories: materials, particle physics

Group theory and first-principles calculations combine to predict which antiferromagnets have potentially useful net surface magnetization.

Antiferromagnetism was discovered in the 1930s by Louis Néel but had long been considered of scientific, not practical, interest. Antiferromagnets (AFM) are internally magnetic, but the magnetic moments of their atoms and molecules are antiparallel to each other, canceling out and resulting in no net magnetization. This cancellation renders bulk antiferromagnets effectively invisible to external magnetic fields, so that their magnetic properties are difficult to harness in applications. Recently, however, a new paradigm has appeared—antiferromagnetism-based spintronics—which seeks to apply antiferromagnets’ unique properties (such as fast spin dynamics, the absence of strong stray fields, and the stability of these materials) to the processing and storage of information [1].

Thin Films of Topological Magnets for Thermoelectric Applications

Posted by in category: energy

A thin film of a topological magnet displays a large thermoelectric effect that doesn’t require an applied magnetic field—a behavior that could lead to new energy-harvesting devices.

The death of Vulcan: Study reveals planet is actually an astronomical illusion caused by stellar activity

Posted by in category: space

A planet thought to orbit the star 40 Eridani A—host to Mr. Spock’s fictional home planet, Vulcan, in the “Star Trek” universe—is really a kind of astronomical illusion caused by the pulses and jitters of the star itself, a new study shows.

Researchers develop 3D model to better treat neurological disorders

Posted by in category: neuroscience

A 3D model developed by West Virginia University neuroscientists shows how implantable stimulators—the kind used to treat chronic pain—can target neurons that control specific muscles to provide rehabilitation for people with neurological disorders such as stroke and spinal cord injuries.
