Researchers have found that a material which incorporates atomically thin layers of water is able to store and deliver energy much more quickly than the same material that doesn't include the water layers. The finding raises some interesting questions about the behavior of liquids when confined at this scale and holds promise for shaping future energy-storage technologies.
Individuals with a slender lower face are about 25 percent more likely to be left-handed. This unexpected finding was identified in 13,536 individuals who participated in three national surveys conducted in the United States. This association may shed new light on the origins of left-handedness, as slender jaws have also been associated with susceptibility to tuberculosis, a disease that has shaped human evolution and which today affects 2 billion people.
Scientists now understand what makes bioluminescent mushrooms glow, which may pave the way to new possibilities for harnessing fungal bioluminescence in analytical and imaging technologies. Bioluminescence is a highly conserved phenomenon that exists in a wide range of organisms; there are roughly 80 different known species of bioluminescent fungi alone scattered across the globe.
Explorers planning to settle on Mars might be able to turn the planet's soil into bricks without needing to use an oven or additional ingredients. Instead, they would need to apply pressure to compact the soil--the equivalent of a blow from a hammer.
In the spring when water temperatures start to rise, rainbow trout that have spent several years at sea traveling hundreds of miles from home manage, without maps or GPS, to find their way back to the rivers and streams where they were born for spawning. Researchers have identified genes that enable the fish to perform this extraordinary homing feat with help from Earth's magnetic field.
New two-dimensional quantum materials have been created with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics. The researchers explored the physics behind the 2-D states of novel materials and determined they could push computers to new heights of speed and power.
Paleontologists have uncovered a new fossil species that sheds light on the origin of mandibulates, the most abundant and diverse group of organisms on Earth, to which belong familiar animals such as flies, ants, crayfish and centipedes. Named Tokummia katalepsis by the researchers, the creature documents for the first time the anatomy of early mandibulates, a sub-group of arthropods with specialized appendages known as mandibles, used to grasp, crush and cut their food.
Peering into laboratory glassware, researchers have watched stem-cell-derived nerve cells arising in a specific region of the human brain migrate into another brain region. This process recapitulates what's been believed to occur in a developing fetus, but has never previously been viewed in real time.
Newborn humpback whales 'whisper' to their mothers to avoid being overheard by killer whales, researchers have discovered. The recordings were the first obtained from tags directly attached to the whales.
Could the bacteria that inhabit our gut influence our food choices? A new study shows, for the first time, that this idea may not be as far-fetched as it seems. Neuroscientists have discovered that gut bacteria 'speak' with the brain to control food choices in animals. They identified two species of bacteria that have a radical impact on animal dietary decisions.
Researchers have created a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction while blocking the current in the opposite direction. Today, researchers are approaching the physical limit in downsizing electronic components.
Researchers recently confirmed it is possible to extract proteins from 80-million-year-old dinosaur bones. The discovery sparks hopes for new insights about evolution and environmental change and could even offer useful clues for drug discovery or the search for extraterrestrial life.
Using human skin cells, neurobiologists have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.
Around 2010, the deep waters of Utah's Great Salt Lake contained high levels of toxic methylmercury. Mercury measurements in waterfowl surrounding the lake led to a rare human consumption advisory for ducks. But by 2015, 90 percent of the deep mercury was gone.
