Fruit flies respond more effectively to danger when in a group
Fruit flies respond more effectively to danger when in a group
Fruit flies respond more effectively to danger when in a group. A research team discovered this behavior as well as the neural circuits which relay this information, opening a new field of research.

Unraveling the light of fireflies
Unraveling the light of fireflies
How do fireflies produce those mesmerizing light flashes? Using cuttingedge imaging techniques, scientists from Switzerland and Taiwan have unraveled the firefly's intricate light-producing system for the first time. Fireflies used rapid light flashes to communicate. This "bioluminescence" is an intriguing phenomenon that has many potential applications, from drug testing and monitoring water contamination, and even lighting up streets using glow-in-dark trees and plants.

Mechanism of action of thalidomide elucidated
Mechanism of action of thalidomide elucidated
Scientists have clarified the workings of thalidomide at the molecular level. Their analysis of various structures indicates that the drug can interfere with cellular processes in two different ways-once preventing and once promoting protein degradation-thus explaining its diverse clinical effects. In the early 1960s, thalidomide - a drug widely prescribed at that time as a sedative and for the treatment of morning sickness in pregnancy - became notorious when it was found to cause birth defects.

Inducing visual function
Inducing visual function
Scientists have resolved the mechanism controlling the maintenance of the light detectors - the cone photoreceptor outer segments - in the retina. With this knowledge, they have been able to induce the formation of functional photoreceptors in cultured retinas derived from embryonic stem cells. This opens up exciting new avenues for the study and treatment of blindness.

A brain area responsible for grasping
A brain area responsible for grasping
A research has shown that limb motor control is regulated by a selective synaptic connectivity matrix between the brainstem and the spinal cord. In particular, the researchers have pinpointed a brainstem area responsible for the control of grasping. This is the first time it has been possible to link defined neuronal circuit elements unequivocally to a specific phase of movement.

A software to identify genetic mutations
A software to identify genetic mutations
A research team developed a computer programme to identify mutations causing certain genetic diseases by analysing the genome sequencing data. The software can also detect the mutations leading to the appearance of tumours in patients with cancer. It is available to researchers all over the world.

A rhythm for development
A rhythm for development
Development of the nematode C. elegans is directed by rhythmic patterns of protein production. As researchers have shown, oscillations with an 8-hour period occur across a wide variety of tissues, structures, cells and genes. The extent of the phenomenon suggests that the process involved could be a fundamental mechanism in the development of many organisms .
