Scientists have devised a method for coaxing mouse embryonic stem cells into forming a highly specific motor neuron subtype. The research provides new insight into motor neuron differentiation and may prove useful for devising and testing future therapies for motor neuron diseases.

A multidisciplinary group of researchers has produced a 3.6-angstrom resolution structure of the human adenovirus. Scientists are working with adenovirus as a vector for gene therapy, but have needed better structural information.

A new study of romantically separated people shows they offer clues to their emotional status in just a few seconds of conversation.

Researchers have developed a new animal model for studying hemophilia A, with the goal of eventually treating people with the disorder. Hemophilia A, a hereditary defect that prevents blood from clotting normally, is caused by a variety of mutations in the factor VIII gene.

When it comes to the mechanics of the human immune system, we are all more alike than previously thought, according to a new study.

A new study shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from felling forests, which sends carbon into the atmosphere and drives global warming. But the research team also noted that big agribusiness has largely replaced small farmers in doing most of the tree cutting in Brazil and Indonesia, which may make it easier to rein in the trend.

Researchers have developed a new fabrication process for high-speed graphene transistors using a nanowire as the self-aligned gate. This new technique does not produce any appreciable defects in the graphene during fabrication, so the carrier mobility is retained. Also, by using a self-aligned approach with a nanowire as the gate, the group was able to overcome alignment difficulties previously encountered and fabricate short channel devices with unprecedented performance.

In two closely related studies, two teams of scientists have discovered the underlying mechanisms that activate a type of immune cell in the skin and other organs. The findings may lead to the development of new therapies to treat inflammation, wounds, asthma and malignant tumors.

More people are likely to believe scientific studies claiming that oil drilling is riskier, not safer, than was previously thought, according to a new study of attitudes in California. What's more the findings show that scientists' efforts to influence public opinion have a limited effect.
