A new study found that 50 minutes of dry heat in an electric cooker decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers to safely reuse limited supplies of ...

Dream or REM sleep is distinguished by rapid eye movement and absence of muscle tone, but electroencephalogram (EEG) recordings are indistinguishable from those of an awake brain. Neuroscientists have now found an EEG si...

When it comes to training neural circuits for tissue engineering or biomedical applications, a new study suggests a key parameter: Train them young.

A new analysis of ancient genomes suggests that different branches of the human family tree interbred multiple times, and that some humans carry DNA from an archaic, unknown ancestor.

Experiments at the Large Hadron Collider suggest that muons and other “second-generation particles” obtain their mass from interacting with the Higgs, further strengthening the Standard... --

Engineers have designed a device that replicates the lining of the colon. With the device, they can grow human colon cells along with oxygen-intolerant bacteria that normally live in the human digestive tract and have be...

Researchers analyzed five biomarkers present in the blood of hundreds of COVID-19 patients, finding elevated levels associated with higher odds of clinical deterioration and death.

Creative chemists employ enzymes to build a complex but promising natural anti-cancer agent called cepafungin I in a lean nine steps.

Placebos reduce biomarkers in the brain of emotional distress, even when a patient knows they are taking one.

LSU Health New Orleans research has unlocked a key fundamental mechanism in the communication between brain cells when confronted with stroke and found DHA not only protected neuronal cells and promoted their survival, b...

Researchers have identified a pattern of longer-term symptoms likely to be experienced by people who were hospitalized with the COVID-19 infection. They include fatigue, breathlessness, psychological distress -- includin...

A team of researchers have developed an algorithm through machine learning that helps predict sites of DNA methylation - a process that can change the activity of DNA without changing its overall structure - and could id...

These strange, long-necked Triassic beasts were able to coexist because they chowed down on different prey.

A new analysis of sibling records from more than 300,000 individuals suggests that some parents continue to reproduce until they have children of both sexes.

The Y chromosome has shrunken drastically over 200 million years of evolution. Even those who study it have used the word 'wimpy' to describe it, and yet it continues to stick around. An Opinion paper outlines a new theo...

Researchers have succeeded in developing a dynamic 3D CT scanning method that shows what happens inside the body during simulated heart massage. The method could help to increase the chance of surviving a cardiac arrest.

Contrary to what has been generally assumed so far, a severe course of COVID-19 does not solely result in a strong immune reaction -- rather, the immune response is caught in a continuous loop of activation and inhibitio...

Despite our broad understanding of the different brain regions activated during rapid-eye-movement sleep, little is known about what this activity serves for. Researchers have now discovered that the activation of neuron...

Scientists have developed a synthetic peptide that can make multidrug-resistant bacteria sensitive to antibiotics again when used together with traditional antibiotics, offering hope for the prospect of a combination tre...

Researchers found a single genetic mutation that leads to reduced growth of a transmissible cancer in Tasmanian devils in the wild. The finding gives hope for the animals' survival and could lead to new treatment for hum...

Children's pester power may contribute to improvements in their family's food environments. A new study highlights the potential for children to influence food consumption and habits at home.

Scientists have discovered that a set of genes with decreased expression in individuals with Down syndrome may lead to clinical abnormalities in this population, such as poor muscle development and heart valve problems. ...
