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.
Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behavior from a radio-loud magnetar—a rare type of neutron star and one of the strongest magnets in the universe.
A U.S. billionaire who made a fortune in tech and fighter jets is buying an entire SpaceX flight and plans to take three people with him to circle the globe this year.
That dream house in southern France that so many fantasise about is going to become uncomfortably hot in coming decades, according to new climate change projections Monday by the country's national weather service.
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.
A 15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at small scales? The answer to this question has important implications for how climate change might shift species' distributions across the globe.
New research from North Carolina State University reveals that probiotic Lactobacillus bacteria use enzymes situationally to manipulate bile acids and promote their own survival in the gut. These findings further elucidate the complicated relationship between bile acids and gut bacteria and could eventually enable researchers to design lactobacilli with therapeutic properties, thereby engineering...
Just as plants and animals on land are keenly attuned to the hours of sunlight in the day, life in the oceans follows the rhythms of the day, the seasons and even the moon. A University of Washington study finds the biological light switches that make this possible.
A previously unknown root trait allows some cereal plants to grow deeper roots capable of punching through dry, hard, compacted soils, according to Penn State researchers, who suggest that harnessing the inherited characteristic could lead to crops better able to deal with a changing climate.
Most snakes get from A to B by bending their bodies into S-shapes and slithering forward headfirst. A few species, however—found in the deserts of North America, Africa and the Middle East—have an odder way of getting around. Known as "sidewinders," these snakes lead with their mid-sections instead of their heads, slinking sideways across loose sand.
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 including doctoral student Courtney Wagner and associate professor Peter Lippert from the University of Utah, have found a way to glean the valuable information in...

The temperature of a planet is linked with the diversity of life that it can support. MIT geologists have now reconstructed a timeline of the Earth's temperature during the early Paleozoic era, between 510 and 440 million years ago—a pivotal period when animals became abundant in a previously microbe-dominated world.
New research out of the University of Chicago has found evidence that the lobe-finned fish species Tiktaalik roseae was capable of both biting and suction during feeding, similar to modern-day gars. These results, published on Feb. 1 in the Proceedings of the National Academy of Sciences, provide evidence that bite-based feeding originally evolved in aquatic species and was later adapted for use...
Space tourism company Virgin Galactic said Monday it planned a new test flight for its SpaceShipTwo craft this month after an aborted test in early December.
From biofuels and other commodity chemicals to methane production, genomic study peers into the mysteries of a goat's gut.
The virtual conferencing that has replaced large, in-person gatherings in the age of COVID-19 represents a drastic reduction in carbon emissions, but those online meetings still come with their own environmental costs, new research from the University of Michigan shows.
Researchers build on previous studies into detection technologies and reconstruction algorithms for muon tomography, to develop a full-scale muon tomograph prototype.
