Oops! Researchers publish new findings on the brain's response to costly mistakes

It happens to all of us, no matter how hard we try. Whether it's deleting a computer file and realizing a split-second later that we can't get it back, or dropping a bag of groceries, or realizing that our gas tank is nearly empty on a lonely stretch of highway, we all make mistakes that aren'...

Strawberries by design

...commented: "Over the years, scientists have worked hard to find a system that would enable the efficient transformation of strawberry. However, these efforts have fallen short of the requirements to support large-scale studies of gene function in fruit crops." He added: "What sets this work apart is the c...

U-M researchers take new approach to defeating Gram-negative bugs

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

... arthropods ?creatures with jointed appendages and hard outer shells. While the human species loves lobster, other mammalian species, in particular whales, depend on different arthropods, such as the tiny crustaceans called copepods and krill. Twenty percent of known marine species in the Gulf of Ma...

Study indicates dramatic rise in antibiotic-resistant community-acquired staph infections

...rted following up on the findings: "We have worked hard on educating physicians, including those in training, about the need to consider community-acquired MRSA infections," he says. "There have been changes in recommendations for empiric therapy for skin and soft tissue infections." Dr. Blumberg and hi...

Study finds 60 new genes controlled by DNA snippet

...lly include just six to 10 base pairs, making them hard to find. As a human embryo develops from a single cell into tens of billions of cells, DNA must be read and copied again and again to supply each cell with its needed copy. Over time, random changes, or mutations, are inserted into the code during t...

Cincinnati surgeons report new treatment for often-fatal injury

...ea in the chest. "Used alone, extender cuffs are hard to align and often slip into the defect to cause further complications," says Dr. Giglia. "Using a fixed stent provides an easy-to-see 'scaffolding' that can guide the surgeon to more accurately secure the extender cuffs and create a strong seal." ...

Carnegie Mellon researchers discover new cell properties

The researchers also think that the stiffer lamina in HGPS patients may be unable to communicate the proper biological signals to the DNA inside the nucleus to help the cell grow, which contributes to the disease. Islam, an assistant profess...

As they suggest, there could have been a continual decrease in Sonic as the limbs reduced until the modern version of the animal arrived." The study itself, combining foss...

Bird flu study highlights need to vaccinate flocks effectively

...ut farmers realising it. In practice, it is very hard to protect more than about 90 per cent of the birds in any given flock, and protection levels are usually much lower than this. The new study estimates that protection levels of more than 95 per cent would be needed to guard against silent spread. ...
