Probiotic Lactobacillus bacteria use enzymes situationally to manipulate bile acids and promote their own survival in the gut.

Scientists thought that reindeer lichens (moss-looking organisms that form a major part of reindeer diets) reproduced mainly asexually by cloning themselves. But it turns out, reindeer lichens are having a lot more sex than scientists expected. In a new study, researchers found that the reindeer lichens they examined have unexpected levels of genetic diversity, indicating that the lichens have...

Researchers have revealed that colorectal cancer tissues contain at least two types of fibroblasts, namely, cancer-promoting fibroblasts and cancer-restraining fibroblasts, and that the balance between them is largely involved in the progression of colorectal cancer. Their findings suggest that artificially altering the balance between the two types of cells could curb the spread of colorectal...

Risk for a severe form of retinopathy of prematurity, which can cause blindness in extremely premature babies, was halved when the newborns were given a new supplement combining various fatty acids.

There are fossils, found in ancient marine sediments and made up of no more than a few magnetic nanoparticles, that can tell us a whole lot about the climate of the past, especially episodes of abrupt global warming. Now, researchers have found a way to glean the valuable information in those fossils without having to crush the scarce samples into a fine powder.

Evidence of an impending breakup may exist in the small words used in everyday conversations months before either partner realizes where their relationship is heading, according to new psychology research.

From biofuels and other commodity chemicals to methane production, genomic study peers into the mysteries of a goat's gut.

Researchers build on previous studies into detection technologies and reconstruction algorithms for muon tomography, to develop a full-scale muon tomograph prototype.

Theoretical physicists are working on a theory that goes beyond the Standard Model of particle physics. The central element is an extra dimension in spacetime. Until now, the scientists have faced the problem that the predictions of their theory could not be tested experimentally.

Social media is increasingly used to spread fake news. The same problem can be found on the capital market - criminals spread fake news about companies in order to manipulate share prices. Researchers have developed an approach that can recognize such fake news, even when the news contents are repeatedly adapted.

When it comes to saving endangered species of a certain size, conservationists often have to think outside the box.

How to study the stages children go through as they play together has been highlighted in new research.

Restoring an enzyme that maintains the way chromosomes are packed inside cells may lead to new therapies for some blood cancers, according to a new study.

Taking a particular type of medication to treat enlarged prostate is associated with a reduced risk of developing Parkinson's disease, according to a large observational study by researchers at the University of Iowa, and colleagues in Denmark and China. The findings, published in JAMA Neurology, suggest that terazosin, and similar medications, might have potential to prevent or delay the...

A new kind of wearable health device would deliver real-time medical data to those with eye or mouth diseases.

Winter survival of honey bee colonies is strongly influenced by summer temperatures and precipitation in the prior year, according to researchers, who said their findings suggest that honey bees have a 'goldilocks' preferred range of summer conditions outside of which their probability of surviving the winter falls.

Toxin-antitoxin (TA) systems are now known to negatively control plasmid replication.

Researchers have discovered how to make materials that snap and reset themselves, only relying upon energy flow from their environment. The discovery may prove useful for various industries that want to source movement sustainably, from toys to robotics, and is expected to further inform our understanding of how the natural world fuels some types of movement.

Engineers model the hypothetical threats from toxins released when above-ground storage tanks fail during a storm. Using data from hurricanes Ike and Harvey and from the Houston Ship Channel, they illustrate potential atmospheric pollutants during and after a disaster.

Researchers set out to understand gift giving dynamics in these settings and how a giver's and a recipient's evaluation of the giver's gift is influenced by the other gifts the recipient receives.

Uncovering the activities of the organs, tissues and cells responsible for the body's stress response as they've never before been seen revealed new cells and possible new drug targets.

Antarctic ice is melting, contributing massive amounts of water to the world's seas and causing them to rise - but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years' worth of satellite data indicates.

Engineering researchers have developed and demonstrated a new approach for designing photonic devices. The advance allows them to control the direction and polarization of light from thin-film LEDs, paving the way for a new generation of virtual reality (VR) and augmented reality (AR) technologies.

Researchers found that inhaling unfragmented hyaluronan improves lung function in patients suffering from severe exacerbation of chronic obstructive pulmonary disease (COPD). Hyaluronan, a sugar secreted by living tissue that acts as a scaffold for cells, is also used in cosmetics as a skin moisturizer and as a nasal spray to moisturize lung airways. Utilized as a treatment, hyaluronan decreased...
