A new study finds that depressed mood or anxiety exhibited in COVID-19 patients may be a sign the virus affects the central nervous system. These two psychological symptoms were most closely associated with a loss of sme...

A study published earlier this year claiming the coronavirus may have jumped from dogs to humans is scientifically flawed, offering no direct evidence to support its conclusions, according to a collaborative group of int...

As data accumulates on COVID-19 cases and deaths, researchers have observed patterns of peaks and valleys that repeat on a near-weekly basis. A new study reports that those oscillations arise from variations in testing p...

The coronavirus pandemic's knock-on impact on healthcare for tuberculosis, malaria and HIV could lead to deaths on a similar level to those from covid-19 itself in some parts of the world, a new analysis finds

An investigational vaccine, mRNA-1273, designed to protect against SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), was generally well tolerated and prompted neutralizing antibody activity in health...

Researchers have proven that a single gene can convert female Aedes aegypti mosquitoes into fertile male mosquitoes and identified a gene needed for male mosquito flight.

Propagate light through any kind of medium -- be it free space or biological tissue -- and light will scatter. Robustness to scattering is a common requirement for communications and for imaging systems. Structured light...

A new experiment places limits on the smallest possible increment of time --

A new study reveals how two key neural circuits dictate the choice between social approach and avoidance. The findings will enable researchers to evaluate social interventions in autism.

Propagate light through any kind of medium - be it free space or biological tissue - and light will scatter. Robustness to scattering is a common requirement for communications and for imaging systems. Structured light, ...

Researchers have showed that HLA-G gene regulates male-to-female ratio at birth. The study strengthens earlier findings of the vulnerability of male fetuses to preeclampsia.

Scientists have discovered a new link between impaired brain energy metabolism and delirium -- a disorienting and distressing disorder particularly common in the elderly and one that is currently occurring in a large pro...

The death of a twin, especially earlier in life, can increase the risk of their surviving twin being diagnosed with a psychiatric disorder, finds a new study.

Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of char...

A new remote weight-loss program, called Opt-IN, provides maximum weight loss for the lowest cost and with much less hassle than the gold-standard National Diabetes Prevention Program (DPP), the most successful behaviora...

New research, based on earlier results in mice, suggests that our brains are never at rest, even when we are not learning anything about the world around us.

The Fermilab magnet team has done it again. After setting a world record for an accelerator magnet in 2019, they have broken it a year later.

(ETH Zurich Department of Physics) In combined theoretical and experimental work, physicists at ETH Zurich introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The disco...

Memories of specific events and experiences do not remain static in brain areas. Instead, patterns of brain activity that store information continually changes, even when we are not exposed to new stimuli.

Quercetin, a protein found in pickled capers, modulates potassium ion channels in the KCNQ gene family. These channels are influential in human health, and their dysfunction is linked to diseases, including diabetes, epi...

Artificially inducing peripheral inflammation in mice triggered the sudden onset of delirium-like cognitive dysfunction, and this was mediated by a disturbance in energy metabolism.

An oncogene believed to be responsible for glioblastoma brain cancer has been identified. AVIL, a gene that normally helps cells to maintain their shape and size, can shift into overdrive, causing cancer cells to form an...
