New research shows that it is undamaged nerve fibres that cause ongoing spontaneous pain, not those that are injured.

These unexpected findings, by Dr Laiche Djouhri, Professor Sally Lawson and colleagues from the University of Bristol, UK, are reported in the Journal of Neuroscience today [25 January, 2006].

Previous research into ongoing chronic pain has tended to focus on the damaged nerve fibres after injury or disease and overlooked the intact fibres. This new unders

Adult stem cells may be free of the ethical concerns that hamper embryonic stem cell research, but they still pose formidable scientific challenges. Chief among these is the doggedness with which adult stem cells differentiate into mature tissue the moment they’re isolated from the body. This makes it nearly impossible for researchers to multiply them in the laboratory. And because adult stem cells are so rare, that makes it difficult to use them for treating disease.

Scientists at the Johnson Space Center in Houston were excited and awed Tuesday by what they saw when the sample-return canister from the Stardust spacecraft was opened.

“It exceeds all expectations,” said Donald Brownlee, a University of Washington astronomy professor who is principal investigator, or lead scientist, for Stardust. “It’s a huge success. We can see lots of impacts. There are big ones, there are small ones.”

Stardust returned to Earth in a spectacular re-entr

Scientists from across the world came together in London on 12-13 January to review the scientific and technical status of the LISA mission, the world’s first gravitational wave observatory, at a meeting organised by the Royal Astronomical Society (RAS) and the Institute of Physics.

Scheduled for launch in 2016, LISA will be the largest scientific instrument ever constructed, consisting of three spacecraft, each separated by 5 million kilometres (3 million miles). Its task will

Data strikingly similar to Finnish studies

Using technology that allows DNA from thousands of genes to be collected and surveyed on a 3 x 1½-inch chip, University of Utah medical researchers have confirmed that a region on a single chromosome probably harbors a gene that causes autism. The researchers at the U School of Medicine made the finding by tracing variations in the DNA of an extended Utah family that has a high occurrence of the disorder and whose members are descended

Tired of resigning yourself to wearing uncomfortable footwear or hunting for hours in search of the right shoes, but think a made-to-order pair will be prohibitively expensive? Think again. A European project has come up with a solution.

Around 300 people across Europe are currently wearing footwear that better fits their feet thanks to trials carried out by the ERGOSHOE project last year. Many more are likely to do the same as the European Commission-funded initiative brings it
