Lobster traps going high tech

New England lobstermen have gone high tech by adding low-cost instruments to their lobster pots that record bottom temperature and provide data that could help improve ocean circulation models in the Gulf of Maine. Environmental Monitors on Lobster Traps, or eMOLT, is a partnership involving NO...

How mirror neurons allow us to learn and socialize by going through the motions in the head

The old adage that we can only learn how to do something by trying it ourselves may have to be revised in the light of recent discoveries in neuroscience. It turns out that humans, primates, some birds, and possibly other higher animals have mirror neurons that fire in the same pattern whether per...

70 years old and going strong with Down syndrome and no dementia

Washington, DC (August 18, 2008) In the world of Down syndrome, 'Mr. C' is a rarity. A real person whose progress has been tracked for the past 16 years, at seventy, 'Mr. C' has well surpassed the average life expectancy of a person with Down syndrome, currently in the late fifties, but in the te...

National Zoo scimitar-horned oryx going into the wild

A male scimitar-horned oryx from the Smithsonians National Zoos Conservation and Research Center in Front Royal, Va., is playing an important role in ensuring the species does not vanish from the planet. The oryx, along with eight others from American and European zoos, was sent to Tunisia in ...

Birds going extinct faster due to human activities

Embryonic stem cells, prized for their astonishing ability to apparently transform into any kind of cell in the body, acquire their identities in part by interacting with their surroundings - even when they are outside of the body in a laboratory dish, University of Florida scientists report. Us...

EGF receptor activation prevents microbes from going more than skin deep

Our skin not only serves as a physical barrier against infection but skin cells themselves can mount an immune response to kill invading microbes by producing antimicrobial polypeptides (AMPs). As overt infection in the skin is a rare event, researchers have theorized that AMPs must not only help...

When the going gets tough, slime molds start synthesizing

In times of plenty, the uni-cellular slime mold Dictyostelium discoideum leads a solitary life munching on bacteria littering the forest floor. But these simple creatures can perform heroic developmental acts: when the bacterial food supply dries up, Dictyostelium amebas band together with their ne...

Watch your step when the going gets rough

Placing your foot accurately is a complicated process. If something moves where you plan to place your foot then you can adjust your step while your foot is swinging through. Experts thought previously that if nothing changed in the path, or in your plans, then the place where your foot will land i...

The shape of things to come: Morphology database going global

A Florida State University researcher who specializes in the evolutionary history of wasps is now creating a buzz about a new way for scientists to store, share and study plant and animal images.

Wildfires set to increase 50 percent by 2050

...

Cancer's distinctive pattern of gene expression could aid early screening and prevention

They have to slip by the normal surveillance to survive and grow." To find the differences, that means always looking at healthy ...

URI researcher sheds light on 'man-eating' squid; finds them timid, nonthreatening

Scientists discover gene mutation responsible for hereditary neuroendocrine tumor
