Modified mushrooms may yield human drugs

...hese genetic elements in the plasmid and insert it back into the bacterium," he added. The researchers then snipped small pieces off the mushroom's gill tissue and added it to a flask containing the altered bacterium. Over the course of several days, as the bacterium goes through its lifecycle, it tr...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...e surfaces of nerve cells that carry pain messages back and forth between an osteoarthritic jaw joint and the spinal cord. Thus, nerve cells involved in pain transmission, with so many more receptors on their surfaces, became drastically more responsive to the naturally occurring painkiller, researchers f...

For many insects, winter survival is in the genes

...at-shock proteins" ensure that the insects will be back to bug us come spring. A study of flesh flies and a handful of other insects suggests that they have an arsenal of protective heat-shock proteins that are turned on almost as soon as the temperature dips. Until this new study, researchers knew of ...

An 'elegant' idea proves its worth 25 years later

...ersity and the Medical College of Wisconsin looked back at 299 urea cycle disorder patients with a total of 1,181 hyperammonemia "episodes" from 118 hospitals around the United States from August 1980 until March 2005. The regimen consisted of high-dose intravenous sodium phenylacetate and sodium benz...

Arctic ice retreating more quickly than computer models project

...because regions of sea ice, which reflect sunlight back into space and provide a cooling impact, are disappearing. In contrast, darker areas of open water, which are expanding, absorb sunlight and increase temperatures. This feedback loop has played a role in the increasingly rapid loss of ice in recent y...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

... primitive root of the green plant lineage, dating back nearly 1.5 billion years. Today, these microscopic, free-living creatures, among the smallest eukaryotes ever characterized, barely a micron in diameter, contribute to a significant share of the world’s total photosynthetic activity. These "picophyt...

Cancer patients monitor fatigue in real time

"Their mood may affect their recall. They may have been experiencing pain in addition to fatigue, and that affects...

First clinical trial of gene therapy for childhood blindness

The new technique that will be used in the trial involves inserting healthy copies of the gene into the cells of...

A frown or a smile? Children with autism can't discern

...ere averted; with the other half, the faces stared back at the children. With the typically developing group, the researchers found significant differences in activity in a part of the brain called the ventrolateral prefrontal cortex (VLPFC), which is known to play a role in evaluating emotions. While ...

Preliminary results place most mammoth finds in the Lake Lewis area at elevations of 600 to 1,000 feet, which echoes the distribution...

When all of the pieces are inserted, the nylon mesh is held snugly against the inner stent. A gap forms between the mesh and the ...

Egyptians, not Greeks were true fathers of medicine

Scientists examining documents dating back 3,500 years say they have found proof that the origins of modern medicine lie in ancient Egypt and not with Hippocrates and the Greeks. The research team from the KNH Centre for Biomedical Egyptology at The University of Manchester discovered the ev...

The device then cross references the reflections with a built-in digital camera and GPS, and feeds the information into an attached laptop. Software is then used to create a detailed and very accurate 3D computer model of the location....

Percutaneous aortic valve replacement safe, successful in high-risk patients
