Following a concussion or mild traumatic brain injury (TBI), patients may suffer from light sensitivity or photophobia, making it challenging to return to normal activities. A new study found wearing certain color-tinted lenses may be a good alternative to dark sunglasses.

A microorganism that thrives in a hot spring draws its nutrients from low-energy sources rather than rich ones -- and scientists can't figure out why.

Muscles require energy to perform all of the movements that we do in a day, and now, for the first time, researchers have shown how muscles 'request' more energy from fat storage tissues in fruit fly models. They also discovered that this circuit is dependent on circadian rhythms, which could have implications for obesity in humans.

Repair petitions filed in the wake of the 1918 Puerto Rico earthquake and tsunami, stored and forgotten in the San Juan archives for nearly 100 years, are giving scientists a house-by-house look at the damage wrought by the magnitude 7.3 event.

Lower tariffs on high-fructose corn syrup (HFCS) in the North American Free Trade Agreement (NAFTA) were linked to higher supply and likely consumption of added sweeteners in Canada, including HFCS, found new research.

A group of astronomers have shown that the fastest-moving stars in our galaxy -- which are traveling so fast that they can escape the Milky Way -- are in fact runaways from a much smaller galaxy in orbit around our own.

Over 7 million tons of mollusc shells are discarded by the seafood industry each year as unwanted waste -- and the vast majority of these shells are either thrown in landfills or dumped at sea. Researchers are looking at environmentally and economically sustainable options for these biomaterials.

Ancient mitochondrial DNA from the femur of an archaic European hominin is helping resolve the complicated relationship between modern humans and Neanderthals. The genetic data provides a timeline for a proposed migration out of Africa that occurred after the ancestors of Neanderthals arrived in Europe by a lineage more closely related to modern humans.

Many bat species catch food 'on the wing' without touching the ground, but how do they do it? A new study has analyzed the aerodynamics of bats performing maneuvers during flight.

In the harshest of environments in far-east Russia, scientists have discovered a new mineral, which could revolutionize the future of the mining industry.

A ground-breaking new study challenges the assumption that moral decisions are strongly context dependent and cannot be modeled or described algorithmically, finding that human behavior in dilemma situations can be modeled by a simple value-of-life-based model. The research suggests that human moral behavior can be well-described by algorithms and used by machines to manage moral dilemmas on the road.

After 12 weeks of taking an anti-asthma drug, a subset of patients with type 2 diabetes showed a clinically significant reduction in blood glucose during a randomized, double blind, placebo-controlled clinical trial, report researchers.

Immune cells in the brain trigger overeating and weight gain in response to diets rich in fat, according to a new study in mice.

A graphene-based spin field-effect transistor has been used in an operating at room temperature. Using the spin of the electrons in graphene and other layered material heterostructures the researchers have produced working devices as a step towards integrating spintronic logic and memory devices.

Today, zebrafish is rising as a new experimental animal model that can replace or supplement rodents such as mice. A research team has succeeded in measuring multichannel EEG of zebrafish using non-invasive method, which enables precise observation and study on the generation of EEG in specific area of the brain and the direction of EEG propagation. The technique is expected to be useful in the development of new drugs for the treatment of brain diseases such as epilepsy syndrome.
