A team of Spanish and British scientists has developed a “laser ablation” method that makes it possible to detect variations in the sulfur isotopes of a single hair over time. This information shows up changes in a person’s eating habits and their movements between different countries, which could help police to undermine the alibis of [...]

Scientists have generated DNA-like compounds that effectively inhibit the cells responsible for the most common and serious form of lupus. The findings could eventually lead to new treatments for this difficult disease, which affects up to one million Americans.
Researchers have identified the locking mechanism that allows some neurons to form synapses to pass along essential information. Mutations of genes that produce a critical cell-adhesion molecule involved in the work were previously linked to autism.
