People with mild traumatic brain injury who are exposed to early morning blue light therapy may experience a decrease in depression and other concussion symptoms, according to a preliminary study.

Most people know that good oral hygiene - brushing, flossing, and regular dental visits - is linked to good health. Microbiome researchers offer fresh evidence to support that conventional wisdom, by taking a close look at invisible communities of microbes that live in every mouth. Their study found a correlation between people who did not visit the dentist regularly and increased presence of a...

In coastal communities prone to hurricanes and tropical storms, people typically turn to engineered solutions for protection: levees, sea walls and the like. But a natural buffer in the form of wetlands may be the more cost-effective solution.

Researchers demonstrate how they can overcome a persistent challenge known as dendrites to create a metal battery that performs nearly as well as a lithium-ion battery, but relies on potassium -- a much more abundant and less expensive element.

Reproduction specialists recently demonstrated that swamp wallabies ovulate, mate and form a new embryo before the birth of the previous offspring. They thereby continuously support embryos and young at different development stages before and after birth.

Could pumping oxygen-rich surface water into the depths of lakes, estuaries, and coastal ocean waters help ameliorate dangerous dead zones? New work says yes, although they caution that further research would be needed to understand any possible side effects before implementing such an approach.

Some of the extremely low-density, 'cotton candy like' exoplanets called super-puffs may actually have rings, according to new research.

A new machine-learning computer model accurately predicts damaging radiation storms caused by the Van Allen belts two days prior to the storm, the most advanced notice to date, according to a new article.

Engineers study the mechanism that would allow 'smart water' to aid oil recovery from reservoirs.

Whether it's coronavirus or misinformation, scientists can use mathematical models to predict how something will spread across populations. But what happens if a pathogen mutates, or information becomes modified, changing the speed at which it spreads? Researchers now show for the first time how important these considerations are.

New research shows silent mutations are worth a closer look.

A new technology called individual ion mass spectrometry, or I2MS, can determine the exact mass of a huge range of intact proteins.

Abrupt environmental changes, known as regime shifts, are the subject of new research in which shows how small environmental changes trigger slow evolutionary processes that eventually precipitate collapse.

Geologists have studied exposed, 3.2-billion-year-old ocean crust in Australia and used that rock data to build a quantitative, inverse model of ancient seawater. The model indicates the early Earth could have been a 'water world' with submerged continents.

Physicists have experimentally observed spin centers in two-dimensional materials. Such centers can act as quantum bits -- even at room temperature.

Many cities are introducing green areas to protect their fauna. Amongst such measures are flower strips, which provide support to flower-visiting insects, insect- and seed-eating birds. According to the first quantitative assessment of the speed and distance over which urban flower strips attract wild bees, one-year-old flower strips attract 1/3 of the 232 species recorded from Munich since 1997.

Researchers are making progress on answering the question of the origin of life. It could be that life originated from chemical reactions catalyzed by minerals in submarine hydrothermal vents. These reactions still drive the metabolism of the most primitive forms of life today. Hydrogen was both the key to and the fuel for the earliest biochemical processes that marked the beginnings of life.

A new study describes the discovery of a common genetic basis for plant symbioses.

An important new study finds that irrigated crop production accounts for 86 percent of all water consumed in the western US -- and of all the water used on western farms, by far the largest portion goes to cattle-feed crops such as alfalfa and grass hay. To alleviate the severe shortage of water in the region, study authors suggest rotational fallowing farmland could be a simple and affordable...

Subduction zones -- places where one tectonic plate dives beneath another -- are where the world's largest and most damaging earthquakes occur. A new study has found that when underwater mountains -- also known as seamounts -- are pulled into subduction zones, not only do they set the stage for these powerful quakes, but also create conditions that end up dampening them.

By analyzing milk proteins extracted from calcified dental plaque, researchers present the earliest evidence for dairy consumption on the eastern Eurasian Steppe and uncover clues to the origin of mounted dairy pastoralism in Mongolia.

A research collaboration has created open-source software to assist in the creation of quantum materials which could in turn vastly increase the world's computing power.

Tiny, laser-activated magnets could enable cloud computing systems to process data up to 100 times faster than current technologies, a study suggests.

At high species richness, directed loss, but not random loss, of tree species strongly decreases forest productivity. This is shown by data from a big forest project in China. Previous studies based on random species loss could therefore bias the predictions of how more realistic extinction scenarios are likely to affect ecosystem functioning.
