A non-pathogenic fungus can expand in the intestines of antibiotic-treated mice and enhance the severity of allergic airways disease, according to a new study. The findings suggest that alterations in gut microbiota indu...

New 3-D maps of water distribution during cellular membrane fusion are accelerating scientific understanding of cell development, which could lead to new treatments for diseases associated with cell fusion.

About half the size of a lunch box, the Tiny Isothermal Nucleic acid quantification sYstem (or TINY) has shown promise as a point-of-care detector of Kaposi sarcoma-associated herpesvirus (KSHV) in resource-limited setti...

New controls and frameworks are recommended to detect dengue and other infectious diseases and help prevent their spread during the 2020 summer Olympics and Paralympics being held in Tokyo, researchers report.

Human skeletal stem cells that become bone, cartilage, or stroma cells have been isolated from fetal and adult bones. This is the first time that skeletal stem cells, which had been observed in rodent models, have been i...

Scientists have measured the human 'exposome,' or the particulates, chemicals and microbes that individually swaddle us all, in unprecedented detail.

Scientists working to bioengineer the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids. This is the first time scientists have been able to g...

Death rates from drug overdoses in the US have been on an exponential growth curve that began at least 15 years before the mid-1990s surge in opioid prescribing, suggesting that overdose death rates may continue along th...

Researchers have identified an independent prognostic factor, cancer/testis antigen 45, that is associated with extended disease-free survival for women with advanced ovarian cancer. Patients with high levels of CT45 in ...

This is a story about something rare in health psychology: a treatment that has gone from scientific discovery, through development and testing, to dissemination and successful implementation nationwide. In a new study, ...

The ability to acquire manganese during infection is essential for the virulence of Enterococcus faecalis in animals, according to a new study.

Researchers have discovered that a naturally occurring antibiotic called kanglemycin A is effective against Mycobacterium tuberculosis, the bacteria that cause tuberculosis, even in drug-resistant strains.

A head-to-head trial comparing the decades-old steroid, prednisone, and a promising new steroid, vamorolone, finds both act on the same key set of genetic pathways involved in controlling inflammation, indicates a new st...

Using a new technique known as laser-capture RNA seq, that involves cutting out dopamine neurons from a human brain section with a laser, investigators have cataloged more than 70,000 novel elements active in these brain...

A new study offers vivid picture of health consequences of life events and chronic strain among foreign-born Mexicans in farm working communities.

Testing the behavioral reaction to MDMA in octopuses, researchers report they have discovered evidence of an evolutionary link between the sea creatures and humans.

SuperCDMS physicists are testing a way to amp up dark matter vibrations to help them search for lighter particles. A dark matter experiment scheduled to go online at the Canadian underground laboratory SNOLAB in the earl...

The weird 'Ediacaran' fossils have stumped scientists for decades - now fat molecules found inside some of them confirm they are the most ancient animals we know

It may be possible to restore damaged parts of the Great Barrier Reef by electrically stimulating coral fragments grown on underwater metal frames

When you think of fruit flies, many words likely come to mind: buzzing, hovering, annoying...but navigating probably isn't one of them. As it turns out, these tiny insects are known to travel up to nine miles per evening...

What prevents our cells being damaged due to overexposure to iron ions is a protein called lactoferrin, known for its ability to bind tightly to such ions. Researchers used a combined experimental and molecular dynamics ...

Healthcare-associated infections can be reduced by up to 55 percent by systematically implementing evidence-based infection prevention and control strategies, according to a review of 144 studies. The study suggests that...
