The analysis of the youngest pair of identical twin stars yet discovered has revealed surprising differences in brightness, surface temperature and possibly even the size of the two. The study, which is published in the June 19 issue of the journal Nature, suggests that one of the stars formed significantly earlier than its twin. Read [...]

For over a decade, the drug called tPA has proven its worth as the most effective emergency treatment for the most common kind of stroke.

In time, we move on, accepting the loss.But for a substantial minority, it’s impossible to let go, and even years later, any reminder of their loss ? [...]

An Australian research project has found a way to bring forward the detection of early stage Alzheimer?s disease by up to 18 months. The leader of the team that made the discovery, Professor Christopher Rowe of the Austin Hospital in Melbourne, says early diagnosis and treatment presents medical practitioners with the best opportunity to delay [...]

A few mice with a tremor-inducing genetic condition seem to have been almost cured by a transplant of human fetal cells, according to research published in Cell Stem Cell1. Steve Goldman, a neuroscientist at the University of Rochester Medical Center in New York, who led the study, believes it is the first time human cell [...]

  This is the first time that metallic conduction has been seen at the interface between two different organic materials. The discovery could lead to new applications in molecular electronics, such as solar-power cells, and other devices that need to work on very small scales.

Today, at an international conference, a team of European astronomers announced a remarkable breakthrough in the field of extra-solar planets. Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307. Moreover, looking at their entire sample studied with HARPS, the astronomers count [...]
