Pharmacies can now sell PEP and PrEP as over-the-counter drugs.

When people become stressed, their bodies can respond by sweating. Now, researchers are monitoring how much adolescents severely affected by autism sweat in order to better understand when behavioral issues, such as aggr...

For years, scientists thought that these powerful sedatives, which are used to treat anxiety, muscle spasms, and sleeping disorders, worked alone to calm nerves. Now, researchers show that this view of the drugs and the ...

New research may help to explain an intriguing phenomenon inside human cells: how wall-less liquid organelles are able to coexist as separate entities instead of just merging together.

For years, scientists have used cells grown in petri dishes to study the metabolic processes that fuel the immune system. But a new report suggests looking outside the dish and into living organisms gives a drastically d...

Reviewing over thirty years of diaries from a patient diagnosed with Alzheimer's disease, linguists discover how writing style changes as dementia progresses.

An artificial intelligence/machine learning model to predict which scientific advances are likely to eventually translate to the clinic has been developed.

Researchers have now turned a CRISPR RNA-cutting enzyme into an antiviral that can be programmed to detect and destroy RNA-based viruses in human cells.

Scientists describes the mechanisms by which longevity is regulated post-transcriptionally, or after a genetic blueprint has been transcribed from an organism's DNA. The identification of these mechanisms will serve as a...

An antibiotic commonly found at low concentrations in the environment can have major impacts on gut bacteria, report researchers.

Molecular biologists have pinpointed a gene that allows chlamydia to take up DNA from its host environment.

A research team has demonstrated how it could improve upon the ability of nature's exquisitely selective collection of antimicrobial enzymes to attack bacteria in a way that's much less likely to cause bacterial resistan...

Investigators recently developed a phototherapy strategy that was highly effective for removing carbon monoxide in rats.

The presence of specific microbiota, or microorganisms that live in the digestive tract, can prevent and cure rotavirus infection, which is the leading cause of severe, life-threatening diarrhea in children worldwide, ac...

In animals, infections are fought by the immune system. Studies on an unusual virus infecting wild koalas reveal a new form of 'genome immunity.'

Researchers have demonstrated a new, rapid method to obtain donor stem cells for bone marrow transplants using a combination of Viagra and a second drug called Plerixafor. Bone marrow transplants, used mostly in the trea...

The first comprehensive look at the immune system of the fetal gut shows that it is far more developed before birth, and could help develop new maternal vaccines and reveal if we are predisposed to autoimmune diseases be...

The human fetus is considered to be particularly sensitive to environmental contaminants. A team has now been able to demonstrate for the first time how the widespread food estrogen zearalenone behaves in the womb. Using...

Early symptoms of frontotemporal dementia are often confused with symptoms occurring in psychiatric disorders. Researchers show that serum neurofilament levels can be used as a diagnostic tool to differentiate between th...

A group of physicists have used Monte Carlo modelling to produce a consistent theoretical interpretation of accurate experimental measurements of ion beams in liquid water, which is the most relevant substance for simula...

There may be a connection between food comas -- resting after eating -- and the formation of long-term memories, a team of neuroscientists concludes based on its study on brain activity in sea slugs.

Scientists show, on the molecular level, how an experimental vaccine offers long-term protection against the disease.
