Researchers have developed a technique using spun-sugar filaments to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or blood vessels damaged by disease.

While scientists have identified one protein, dystrophin, as an important piece to curing muscular dystrophy, another part of the mystery has eluded scientists for the past 14 years. Now, scientists have identified the location of the genetic material responsible for a molecular compound that is vital to curing the disease.

Climate researchers expected to see wet/dry periods in Brazil’s Nordeste region similar to the rest of South America in the past 9,000 years. But the area experienced the opposite, drought when rain was expected. Using stalagmite data, researchers identify unexpected air circulation as the cause.

A link between increasing levels of indoor particulate matter pollution and the severity of asthma symptoms among children has been found. The study, which followed a group of asthmatic children in Baltimore, Md., is among the first to examine the effects of indoor particulate matter pollution.

A new map of the Earth’s gravitational force based on satellite measurements makes it much less resource intensive to find new oil deposits. The map will be particularly useful as the ice melts in the oil-rich Arctic regions.

Internet-addicted teens seem more prone to aggression than other adolescents, according to new findings from Taiwanese researchers. However, Americans who study violence are not ready to make any conclusions about a possible link.

Researchers report the characterization of an immune system molecule that targets what appears to be an “Achilles heel” of a wide range of influenza viruses — including the viruses responsible for past global pandemics, those causing current common infections, and strains of bird flu believed to pose future world threats.

A layer of “dark cells” in the retina that is responsible for maintaining the health of the light-sensing cells in our eyes has been imaged in a living retina for the first time. The ability to see this nearly invisible layer could help doctors identify the onset of many diseases of the eye long before [...]

Researchers have known that the brain has a remarkable ability to “reprogram” itself to compensate for problems such as traumatic injury. Now, a research article published in the journal Genetics suggests that the brain might also compensate for problems with key neurotransmitters such as serotonin and dopamine. This may open the doors to entirely new [...]
