Picking particles faster than one at a time

...his colleagues decided that concentrating too much attention on the particle itself in the early stages of picking -- for example, approximating its shape and creating a template into which real images are forced to fit, a process common to all previous automatic methods -- simply added to the difficulty. "We ...

What can change in the brain? Electrical synapses, research shows

...ke transitions between sleep and waking, and focus attention on objects of interest. This phenomenon is a form of neural plasticity. Chemical synapses, junctions where neurons communicate using chemical substances, have long been implicated in plasticity. Now, for the first time, Brown University scientists h...

Because individuals with autism typically choose to...

New view of cancer: 'Epigenetic' changes come before mutations

"Greater attention should be paid to the apparently normal cells of patients with cancer or those at risk for cancer, as they might be crucial targets for epigenetic alteration and might be an important target for prevention and screening," he says.

Removing egg from nest may help save endangered whooping crane

...so, a pair of chicks is more likely to attract the attention of a predator and parents can be more attentive if they only have a single chick to protect. Even though long-term fitness is almost the same whether one egg or two is laid, the risk of extinction for the Wood Buffalo-Aransas whooping crane populat...

New genetic test can detect clam disease

...st notes that although red tide got a lot of media attention this year, QPX is actually a bigger problem. The toxins that cause red tide in clams and other shellfish in New England do not kill the shellfish and will wash away once the red tide bloom diminishes, eventually making the shellfish safe to eat. QPX ...

Embryonic stem cells accrue genetic changes
