Scientists have created a 3-D vascular system that allows for high-performance composite materials, such as fiberglass, to heal autonomously, and repeatedly.
A small study of casual marijuana smokers has turned up evidence of changes in the brain, a possible sign of trouble ahead, researchers say.
The proportion of land used to cultivate shade grown coffee, relative to the total land area of coffee cultivation, has fallen by nearly 20 percent globally since 1996. Researchers say the global shift toward a more intensive style of coffee farming is probably having a negative effect on the environment, communities and individual farmers.
The EPA’s recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found.
Like rings of a tree, hair can reveal a lot of information about the past. It can provide information about things like drug use, environmental toxins exposure and hormone levels. And, according to a study, it can also reveal the womb environment in which an infant formed.
Personalized medicine took one step closer to reality recently with the development of plant-derived nanotubes. These nanotubes hone in on specific tissues in the body and deliver their cargo, in this study's case, a healthy gene to help override a dysfunctional copy.
Scientists have solved a decades-old medical mystery– and in the process have found a potentially less toxic way to fight invasive fungal infections, which kill about 1.5 million people a year.
A new scalable, cheap, quick, repeatable and accurate tool uses a single drop of blood to diagnose even mild cases of asthma.
Disturbances at the very edge of Saturn's outer bright A ring, which result from a small icy object, have given scientists an insight into how moons are made.
Engineers have created new ceramic materials that could be used to store hydrogen safely and efficiently. They also have demonstrated that the compounds could be manufactured using a simple, low-cost manufacturing method known as combustion synthesis.
Researchers have succeeded in creating a surface on nanosized cellulose crystals that imitates a biological structure. The surface adsorbs viruses and disables them. The results can prove useful in the development of antiviral ointments and surfaces.
From dental implants that are light, strong and porous enough to bond with bone to surgical implants that dissolve over time, modified metals are dramatically extending biomedical potential.
Coupling commercially available spectral X-ray detectors with a specialized algorithm can improve the detection of uranium and plutonium in small, layered objects such as baggage. This approach enhances the detection powers of X-ray imaging and may provide a new tool to impede nuclear trafficking.
We can learn a lot about volcanoes by studying explosions. The more we can learn about their explosive behavior, the more chance we have of saving lives when they suddenly erupt.
Food is a personal thing; we savor some tastes and despise others. But how does the way we chew and eat our food impact our overall consumption? According to a new study, people perceive foods that are either hard, or have a rough texture, as having fewer calories.
