Newly Born Twin Stars Are Far From IdenticalMon, 23 Jun 2008 14:42:23 +0000The 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 [...] |
Stroke study reveals a key target for improving treatmentMon, 23 Jun 2008 14:30:43 +0000For over a decade, the drug called tPA has proven its worth as the most effective emergency treatment for the most common kind of stroke. But its promise is blemished by two facts: tPA can cause dangerous bleeding in the brain, and its brain-saving power fades fast after the third hour of a stroke. Read [...] |
Study shows that chronic grief activates pleasure areas of the brainMon, 23 Jun 2008 13:51:48 +0000Grief is universal, and most of us will probably experience the pain grief brings at some point in our lives, usually with the death of a loved one. 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 ? [...] |
Advance towards early Alzheimer?s diagnosisMon, 23 Jun 2008 13:39:56 +0000An 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 [...] |
Human cell transplants stop the shiversTue, 17 Jun 2008 12:00:40 +0000A 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 [...] |
Organic insulators transformed into metal-like conductors.Tue, 17 Jun 2008 11:52:16 +0000
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. Read More

A Trio of Super-EarthsTue, 17 Jun 2008 10:10:00 +0000
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 [...] |
