How deformable cells are, and thus how stiff or squishy they are, plays an important role in retaining blood-forming stem cells in their marrow niches and thus preserving their long-term repopulation capabilities.

Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving occurs when the ocean melts the…

Teens who choose to spend time alone may know what's best for them, according to new research that suggests solitude isn't a red flag for isolation or depression.

A new system can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on a Coast Guard cutter, the system…

Current treatments for tuberculosis (TB) are very effective in controlling TB infection caused by Mycobacterium tuberculosis (Mtb). They don't, however, always prevent reinfection. Why this happens is one of the long-standing questions in TB research. A team…

Paleontologists have just reported the world's biggest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. The 13-metre-long T. rex, nicknamed 'Scotty,' lived in prehistoric Saskatchewan 66 million years ago.

Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal axons -- threadlike projections -- to successfully reach their…

The device does not require additional components such as batteries or actuators carried on the back or waist.

More and more products carry ethical labels such as fair-trade or organic, which consumers view positively. Nevertheless, the sales figures of these products often remain low, even though they offer advantages for the environment or for society. A team of…

A scientist has new ways of accelerating the development of new organic materials for electronics. The new approaches could have applications in other types of materials science research.

A new study discovers a mechanism by which molecules affect the plasmonic response of gold nanorods. The mechanism could be used to enhance applications like catalysis that involve plasmon-driven chemistry.

An OU-led project is showing how citizen science programs provide valuable data on rivers in southwestern United States. The ecological and hydrological data obtained from intermittent rivers (rivers that dry at some point in space or time) in Arizona are…

Scientists argue for more 'synthesis' research looking at the big picture of volcanology to complement myriad research efforts looking at single volcanoes.

Physicists developed a new mode of photoacoustic imaging called F-mode. This new mode selectively enhances photoacoustic image features based on the size of the object and the sounds it produces.

Drug therapy may effectively treat a potentially life-threatening condition associated with cirrhosis and other chronic liver diseases, according to a new study.

Roughly a quarter of patients overdue for colorectal cancer screening mailed completed kits back within two months, even if they weren't given any kind of financial incentive.

In a surprising finding, researchers showed the protein NLRP6 aggravated the difficult symptoms of gastrointestinal graft-vs.-host disease. Knocking out this protein in mice led to significantly better survival and less severe GVHD.

Researchers have found warmer average water temperatures in Ontario lakes over the past decade have forced fish to forage in deeper water.

Striking colors that are seen only in the males of some species are partly explained by gene behavior, research into guppy fish suggests.

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed medication for major depressive disorder (MDD), yet scientists still do not understand why the treatment does not work in nearly thirty percent of patients with MDD. Now,…

The methods can be replicated by cities to help them identify which neighborhoods are most at risk and what demographic factors characterize the most vulnerable citizens.

Women who have reached menopause are at a greater risk of developing osteoporosis, which can lead to bone fractures and long-term impairment of mobility. Studies have suggested a link between reduced bone density and low estrogen levels due to menopause, but…

Related individuals of a soil bacterial species live in cooperative groups and exhibit astonishing genetic and behavioral diversity.

There is a wide variety of animals living on the Arctic seabed. Attached to rocks, they feed by removing nutrients from the water using filters or tentacles. But it can take decades for these colonies to become established, and they probably don't achieve…

The ongoing climate changes make it increasingly difficult to predict certain aspects of weather, according to a new study. The study, focusing on weather forecasts in the northern hemisphere spanning 3-10 days ahead, concludes that the greatest uncertainty…

The Italian Crested Newt eats anything and everything it can overpower. Earthworms, mosquito larvae and water fleas are on its menu, but also snails, small fish and even its own offspring. A research team has now studied the newt's chewing behavior and has…

Leaf-feeding caterpillars greatly enrich their intestinal flora by eating soil. It's even possible to trace the legacy effects of plants that previously grew in that soil through bacteria and fungi in the caterpillars.

The giant planet Jupiter was formed four times further from the sun than its current orbit, and migrated inwards in the solar system over a period of 700,000 years. Researchers found proof of this incredible journey thanks to a group of asteroids close to…

Scientists have developed a new complex hydride lithium superionic conductor that could result in all-solid-state batteries with the highest energy density to date.

There is an effective formula for unlocking employees' creative potential, according to new research. Employers should incentivize workers to produce an abundance of ideas -- even mediocre ones -- and then have them step away from the project for an…
