Using a fluorescent probe that lights up when brain cells are electrically active, researchers found they can image the activity of many neurons at once, in mice brains. The technique could allow neuroscientists to analyze circuits within the brain and link them to specific behaviors.

A new study sheds light on how human gut microbes break down processed foods -- especially potentially harmful chemical changes often produced during modern food manufacturing processes.

In a world first, scientists have created the human developmental liver cell atlas that provides crucial insights into how the blood and immune systems develop in the fetus. It maps changes in the cellular landscape of the developing liver between the first and second trimesters of pregnancy, including how stem cells from the liver seed other tissues to support the high demand for oxygen needed...

In an effort to make robots more effective and versatile teammates for Soldiers in combat, researchers are on a mission to understand the value of the molecular living functionality of muscle, and the fundamental mechanics that would need to be replicated in order to artificially achieve the capabilities arising from the proteins responsible for muscle contraction.

If you've ever stopped to watch rain falling on a windowpane, you've seen what happens when two drops of water touch and merge into one. But you probably never imagined that the physics at work in this phenomenon was the key to unlocking a solution for the development of miniaturized personal biological analysis devices.

The fight against liver disease could be helped by the discovery of cells that cause liver scarring.

A research group has discovered a novel cancer-driving mutation in the vast non-coding regions of the human cancer genome, also known as the 'dark matter' of human cancer DNA.

Mothers are often their own toughest critics, but new research shows they judge other mothers just as harshly. According to the results -- which build upon previous work identifying seven stereotypes of mothers -- ideal and lazy mothers drew the most contempt from both working and stay-at-home mothers. The overworked stay-at-home mom also was near the top of the list.

Depression affects women nearly twice as much as men, but unraveling the brain's blueprint that regulates this behavior, let alone identifying specific molecular differences between sexes, has proven difficult. Researchers, however, have found and flipped a switch in the brain, revealing a single circuit in mice that activates during stress and is controlled by testosterone.

A recent study explores whether right whale mother-calf pairs change their vocalizations to keep predators from detecting them.

Researchers report that the growing appetite for animal protein in low- to middle-income countries has resulted in a smorgasbord of antibiotic consumption for livestock that has nearly tripled the occurrence of antibiotic resistance in disease-causing bacteria between 2000 and 2018. The researchers found that antibiotic resistance in livestock was most widespread in China and India, with Brazil...

Researchers have gained new insights into the pathogen that causes tuberculosis. The work provides the basis for a new approach in antibiotic therapy.

Scientists have combined graphene and single-walled carbon nanotubes into a transparent hybrid material with conductivity higher than either component exhibits separately.

New brain imaging research debunks a controversial theory about dyslexia that can impact how it is sometimes treated. The cerebellum, a brain structure traditionally considered to be involved in motor function, has been implicated in the reading disability, developmental dyslexia, however, this 'cerebellar deficit hypothesis' has always been controversial. The new research shows that the...

A team of researchers at the Georgia Institute of Technology has developed a new process that could help gain new insights into high-entropy alloys and help characterize their properties.

A new, multicenter study has determined how a single mutation in splicing factor 3b subunit 1 (SF3B1), the most frequently mutated splicing factor gene, drives the formation of many cancers.

Researchers have used the method of single-particle spectroscopy to study electroluminescence in light-emitting devices. They discovered that efficient charge funneling between individual perovskite nanocrystals and the phenomenon of emission blinking are responsible for the low efficiencies of perovskite light-emitting devices.

Before life, there was RNA: Scientists show how the four different letters of this genetic alphabet could be created from simple precursor molecules on early Earth -- under the same environmental conditions.

Many farmers across sub-Saharan Africa try to coax crops out of sandy soils that are not ideal for holding water and nutrients. Traditional approaches would have them apply more fertilizers and use irrigation, but both require access to resources and infrastructure that many do not have. A relatively new technology modeled for eight African countries, and currently being tested in Zimbabwe, shows...

How do some neutron stars become the strongest magnets in the Universe? Astrophysicists have found a possible answer to the question of how these so-called magnetars form. Researchers have used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.

Biological siblings of people with gambling disorder also display markers of increased impulsivity and risk-taking, according to a new psychology study. The findings suggest people with gambling disorder -- a psychiatric term for serious gambling problems -- may have pre-existing genetic vulnerabilities to the illness.

This research raises questions as to whether current diagnoses accurately reflect the underlying neurobiology of mental illness. The findings, just published in the leading peer-reviewed medical journal, JAMA Psychiatry, highlight the need for more individualised approaches to defining mental illness.

A clinical perspective article reviews various imaging manifestations of electronic nicotine delivery systems such as e-cigarettes, vape pens, and hookah tanks. Despite the lack of a standardized case definition for vaping-associated lung injury, the radiologist may be the first person to prompt the clinical team to ask about relevant exposures like hypersensitivity pneumonitis, diffuse alveolar...

Scientists have developed CRISPR-BEST, a new genome editing tool for actinomycetes. It addresses the problem of genome instability caused by DNA double-stranded breaks in current CRISPR-technologies.
