Researchers at the Center for Quantum Information and Quantum Biology at Osaka University used trapped ions to demonstrate the spreading of vibrational quanta as part of a quantum random walk. This work relies on their e...

Researchers have developed a new X-ray contrast agent. The contrast agent is easier to use and distributes into all blood vessels more reliably, increasing the precision of vascular imaging. This reduces the number of an...

Light carrying photon momentum can push and pull microparticles through momentum exchange. This momentum exchange process generates optical forces, which either attracts (conventional optical tweezers), pushes (radiation...

High-energy polarized electron beams are widely used in high-energy physics (linear colliders), nuclear physics and material science. However, such polarized electron beams are usually generated on conventional accelerat...

Researchers have found that the chance of a false negative result -- when a virus is not detected in a person who actually is, or recently has been, infected -- is greater than 1 in 5 and, at times, far higher.

The COVID-19 pandemic has magnified the social, educational and health care disparities already plaguing the nearly 40 million Americans the US Census Bureau estimates are living in poverty. Perhaps the hardest hit membe...

Giving beneficial bacteria to stressed mothers during the equivalent of the third trimester of pregnancy prevents an autism-like disorder in their offspring, according to a new animal study.

Researchers hope giving Remdesivir along with a powerful anti-inflammatory could be the key to treating the most severe COVID-19 cases.

In women with a history of miscarriage, higher levels of physical activity were associated with a greater risk of subclinical, or very early, pregnancy loss, according to new research. Among women with confirmed pregnanc...

Knocking out the immune cytokine IL-6 exacerbates symptoms in HD model mice and affects neural connection genes, a new study finds.

In a new study, researchers have discovered how the protein PP2A can inhibit tumor growth in mice. The protein turns off an enzyme that stimulates cell growth, thus inhibiting the development of cancer.

Antibodies for potential use as medicines can be made rapidly in chicken cells grown in laboratories. Researchers refer to their technique as the human ADLib system, short for autonomously diversifying libraries. The tec...

GP's notes currently unavailable to medical researchers could provide clues to help manage major health crises -- like COVID-19. And according to a 'citizens' jury' study at Brighton and Sussex Medical School (BSMS), the...

Plant products ingested by pregnant women through their diet are broken down by the intestinal microbiota into chemical substances, some of which can cross the placental barrier and reach the fetus. These foreign substan...

Depression, anxiety and PTSD might not be disorders at all, according to biological anthropologists. In the paper, the researchers propose a new approach to mental illness that would be informed by human evolution, notin...

A recent study has shown that rejuvenated fibroblasts can recover their ability to self-contract. This encouraging discovery holds great potential for applications in regenerative medicine and stem cell engineering.

(Tokyo University of Science) The interaction between 'transfer RNAs' and the enzymes that help them in protein synthesis has always been the key area of interest for understanding the evolution of the genetic code. Now,...

After natural killer immune cells kill virus-infected cells, T and B immune cells produce cytokines. This makes the immune reaction stronger and results in the cytokine storm associated with severe COVID-19 infection.

Just as a literature buff might explore a novel for recurring themes, physicists and mathematicians search for repeating structures present throughout nature.

Eleven billion years ago, a hot, active, eyeball of a galaxy glared across space. It formed in a violent collision, and could help explain the Milky Way's spiral.

Researchers have developed a new, sophisticated device that delivers vagus nerve stimulation to help treat chronic pain.

A new study reports hyper-connectivity between substructures of the thalamus, and the cerebral cortex may be responsible for auditory hallucinations associated with schizophrenia.
