Bioengineers have developed a hydrogel scaffold for craniofacial bone tissue regeneration that starts as a liquid, solidifies into a gel in the body and liquefies again for removal. The gel conforms to irregular 3D spaces and provides a platform for functional and aesthetic tissue regeneration.
New research suggests that bats use vision to keep track of where they're going and echolocation to hunt tiny insects that most nocturnal predators can't see. The findings add to our scientific understanding of sensory evolution.
Exxon Mobil says the drive for higher living standards around the world will keep demand for electricity and transportation fuels growing even as economies get more efficient and governments put a price on pollution.
A team of researchers has identified a number of areas of improvement in a national database of forensic ballistics evidence used to link guns to violent crimes.
Children get plenty of benefits from music lessons. Learning to play instruments can fuel their creativity, and practicing can teach much-needed focus and discipline. But, Harvard researchers now say that one oft-cited benefit— that studying music improves intelligence— is a myth.
Little is known about the ecological interactions between pathogens and weakened coral at the microscale. Now, researchers have found that stressed coral produce up to five times more of a sulfurous compound that appears to incite the pathogen cells into changing their swimming direction and speed as they home in on the weakened coral.
As one part of the federal government looks to remove restrictions on making phone calls from airplanes, another agency is apparently considering its own prohibition.
Local authorities in Madagascar say 20 people have died since last week because of what they suspect to be an outbreak of bubonic plague.
A collaboration of scientists has introduced a precision instrument that can determine the water loss, or surface renewal, of agricultural systems that are threatened by water scarcity and climate change.
Four nuclear power plants, sources of low-emissions electricity, have announced closings this year. If plants continue to shut down instead of extending operations the nation risks losing 60 percent of its clean electricity starting in 2030, according to a new report.
Researchers have discovered that some banana varieties accumulate specific plant toxins in the immediate vicinity of root tissue that has been attacked by parasites. This local accumulation is crucial for the plant’s resistance to the pest.
A mechanism in the brain that controls tics in children with Tourette Syndrome (TS) has been discovered by scientists. The study could herald new non-drug therapies to help young people with TS overcome the repetitive physical movements and vocal sounds that characterize their condition.
To protect themselves, some animals rapidly change color when their environments change, but chameleons change colors in unusual ways when they interact with other chameleons. Researchers have discovered that these color changes don't happen out-of-the-blue— instead, they convey different types of information during important social interactions.
Poverty may have direct implications for important, early steps in the development of the brain, saddling children of low-income families with slower rates of growth in two key brain structures.
New research suggests that even in the absence of a concussion, blows to the head during a single season of football or ice hockey may affect the brain’s white matter and cognition, or memory and thinking abilities.
Peter Grace, and a team from the Univ. of Colorado at Boulder, found that using morphine to fight pain after abdominal surgery may actually prolong a patient's suffering, doubling or even tripling the amount of time it takes to recover.
