Researchers have successfully grown human, testosterone-producing cells in the lab, paving the way to someday treat low testosterone with personalized replacement cells.

Scientists have revealed how the electrical patterns formed within an embryo initiate a cascade of molecular changes that culminate in the development of cartilage and bone. Prior studies have shown these electrical patterns appear like blueprints of the tissues and organs that eventually take shape as the embryo matures. The new study demonstrates that voltage gated calcium channels 'read' the...

Oregon Medicaid enrollees are less likely to make unscheduled trips to the hospital following the implementation of the state's accountable-care model, new research shows.

Delays and disruptions in airline operations annually result in billions of dollars of additional costs to airlines, passengers and the economy. Airlines strive to mitigate these costs by creating schedules that are less likely to get disrupted or schedules that are easy to repair when there are disruptions -- new research has found a solution using a mathematical optimization model.

Parents often disagree with transportation experts over what streets are safe for children to ride bikes, a new study finds.

A team of scientists have discovered that the fading of infrared light following Type Ia supernovae explosions can be interrupted, with brightness staying the same for up to a year.

Using an atomic-force microscope fitted with an electrode tip 1,000 times smaller than a human hair, researchers have identified in real time how nanoscale catalysts collect charges that are excited by light in semiconductors. It's a discovery that could help efforts to design devices that can store solar power for later use.

The health care market is failing to support new antibiotics used to treat some of the world's most dangerous, drug-resistant 'superbugs,' according to a new analysis.

Scientists have observed changes to the gene-regulating factors during zebrafish development and discovered that modifications to 'histone H3', one of the proteins around which DNA is bound, play an important role in 'zygotic genome activation' or transition of control of zebrafish embryonic development from maternal material to the zygote.

Scientists have spotted a famously elusive particle: The axion - first predicted 42 years ago as an elementary particle in extensions of the standard model of particle physics.

Researchers have identified a pair of proteins believed to be critical for spreading, or metastasizing, breast cancer to bone.

New research finds dog owners are often inaccurate when measuring out kibble using a scoop, putting the dogs at risk of under-nourishment or weight gain.

Chemists transform their laser-induced graphene into an air filter that not only traps pathogens but also kills them with a small blast of electricity.

Scientists have discovered that predatory bacteria like the cholera pathogen can steal up to 150 genes in one go from their neighbors. The study sheds light on one of the most fundamental mechanisms of horizontal gene transfer.

Stick and leaf insects are a strikingly bizarre group of insects with a worldwide distribution. They are famous for their impressively large body size and their remarkable ability to camouflage themselves as twigs, leaves or bark in order to hide from potential predators. A team of international researchers has now generated the first phylogenomic tree of these insects.

Scientists have long known that nodulation is important to plant health. Nodulation occurs when nodules, which form on the roots of plants (primarily legumes), form a symbiotic relationship with nitrogen-fixing bacteria that deliver nutrients to the plant. This process is a key part of sustainable agriculture and makes legumes an important source of protein for much of the world. However, recent...

Move over Jupiter; Saturn is the new moon king. A team has found 20 new moons orbiting Saturn. This brings the ringed planet's total number of moons to 82, surpassing Jupiter, which has 79.

A nearly 4,000-year-old burial site found off the coast of Georgia hints at ties between hunter-gatherers on opposite sides of North America, according to new research.

Scientists have carried out a novel statistical analysis to determine for the first time a global picture of how the ocean helps predict the low-level atmosphere and vice versa. They observed ubiquitous influence of the ocean on the atmosphere in the extratropics, which has been difficult to demonstrate with dynamic models of atmospheric and oceanic circulation.

The risk and severity of developing chronic traumatic encephalopathy (CTE) increases with the number of years playing American football according to a new study. These findings reaffirm the relationship between playing tackle football and CTE, and for the first time quantify the strength of that relationship.

The discovery suggests new avenues for devising treatments and is a vital step toward finding a cure.

Researchers have created a miniature robot that can crawl with inchworm-like motion. The underlying technology could one day transform industries from aviation to smart wearables.

Experiments showed that the brain's parahippocampal place area is involved in recognizing a particular kind of place, while the brain's retrosplenial complex is involved in mentally mapping the locations of particular places.

Physicists manage to further narrow down range of the search for dark matter.
