Simulations developed by mathematicians provide new details of how sickle cell disease manifests inside red blood cells, which could help in developing new treatments.

Food scientists have found that people with a diminished ability to taste food choose sweeter -- and likely higher-calorie -- fare. This could put people on the path to gaining weight.

Advances in modern electronics has demanded the requisite hardware, transistors, to be smaller in each new iteration. Recent progress in nanotechnology has reduced the size of silicon transistors down to the order of 10 nanometers. However, for such small transistors, other physical effects set in, which limit their functionality. The recent discoveries of topological materials -- a new class of relativistic quantum materials -- hold great promise for use in energy saving electronics.

Scientists identified two new populations of cells in the brain that potently regulate appetite. The two types of cells, located in a part of the brainstem called the dorsal raphe nucleus, are potential targets for new drugs to treat obesity by controlling the hunger signals that drive the search for and consumption of food.

Saturn’s frigid moon Titan has a curious atmosphere. In addition to a hazy mixture of nitrogen and hydrocarbons, like methane and ethane, Titan’s atmosphere also contains an array of more complex organic molecules, including vinyl cyanide, which astronomers recently uncovered in archival ALMA data. Under the right conditions, like those found on the surface of Titan, vinyl cyanide may naturally coalesce into microscopic spheres resembling cell membranes.

This beautiful clump of glowing gas, dark dust and glittering stars is the spiral galaxy NGC 4248, located about 24 million light-years away in the constellation of Canes Venatici (The Hunting Dogs).

Blue light emitted from digital devices could contribute to the high prevalence of reported sleep dysfunction, suggests new research.

If it's the thought that makes a gift count, here's a thought that can make your gift count extra: Get a little something for yourself. Research shows that gift recipients are happier with a present when the giver got themselves the same present.

Football officials watching slow-motion clips or drivers changing from motorways to 30 mph zones could be unconsciously misjudging speed -- and the motivations behind a person's movements -- because their perceptions of 'normal' have been altered by recent experiences, new research has found.

The protein amyloid beta is believed to be the major cause of Alzheimer's disease. Substances that reduce the production of amyloid beta, such as BACE inhibitors, are therefore promising candidates for new drug treatments. Scientists have recently demonstrated that one such BACE inhibitor reduces the amount of amyloid beta in the brain. By doing so, it can restore the normal function of nerve cells and significantly improve memory performance.

A new study involving mice, suggests that EGCG (epigallocatechin-3-gallate), the most abundant catechin and biologically active component in green tea, could alleviate high-fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment.

In the last third of the 16th century, the Spanish crown set in motion a project to obtain a complete map of the New World. The method thought up for this was to use surveys, known as Relaciones Geográficas. A questionnaire with more than 50 questions was sent to each settlement. These also had to be completed with a map of the local region.

The Anthropocene has transformed England, outline researchers in a new report. The Anthropocene -- the concept that humans have so transformed geological processes at Earth's surface that we are living in a new epoch -- was formulated by Nobel Laureate Paul Crutzen in 2000.

Research scientists were successful in producing broadband laser light in the mid-infrared range with the help of liquid-filled optical fibers. With these fibers, they also provided experimental proof of a new dynamics of hybrid solitons -- a new type of temporally and spectrally stationary light waves resulting from the unique characteristics of the liquid core.

The structure of a protein key to the survival and spread of a virus that affects salmon could help researchers form strategies to treat the flu in humans.
