Novel technique to produce stem cells from peripheral blood

Stem cells are a valuable resource for medical and biological research, but are difficult to study due to ethical and societal barriers. However, genetically manipulated cells from adults may provide a path to study stem cells that avoid any ethical concerns. A new video-protocol in JoVE (Journal of Visualized Experiments), details steps to generate human induced pluripotent stem cells (iPSC) from...

Stem cells could heal equine tendon injuries

Tendon injuries affect athletic horses at all levels. Researchers from the University of Connecticut are studying the use of stem cells in treating equine tendon injuries. Their findings were published Oct. 16 in the Journal of Animal Science Papers in Press.

Can BlackBerry 10 Help RIM Rival Windows 8?

Have no fear. Research in Motion's BlackBerry OS 10 is (almost) here. The struggling Canadian company says it has reached a "critical milestone" for its new BB 10 software that could help pull the company out of its nosedive. The new software is expected for a March 2013 release and is now being tested by 50 carriers around the world. "I'm very pleased to confirm that we have passed a critical...

NASA adds up Hurricane Sandy's rainfall from space

NASA's Tropical Rainfall Measuring Mission, or TRMM, satellite acts as a rain gauge in space as it orbits the Earth's tropics. As TRMM flew over Hurricane Sandy since its birth on Oct. 21 it was gathering data that has now been mapped to show how much rain the storm dropped along the US eastern...

Researchers find three unique cell-to-cell bonds

The human body has more than a trillion cells, most of them connected, cell to neighboring cells. How, exactly, do those bonds work? What happens when a pulling force is applied to those bonds? How long before they break? Does a better understanding of all those bonds and their responses to force have implications for fighting disease? A research team is answering those questions as it studies the...

Softening arteries, protecting the heart: Connection between 'good' cholesterol and collagen in heart health

Arterial stiffening has long been considered a major risk factor for cardiovascular disease. Keeping arteries soft and supple might reduce disease risk, but the mechanisms of how arteries stave off hardening has remained elusive. Researchers have discovered that the protein apolipoprotein E plays a major role in maintaining arterial softness by suppressing production of the extracellular...

Shoppers Say: Thanksgiving Before Christmas, Please!

Americans want to finish eating their Thanksgiving dinner before they turn their attention to St. Nick.  According to a new survey, 78 percent of Americans think stores should not play Christmas music until after Thanksgiving, and 75 percent say stores also should refrain from Christmas decorations until after Thanksgiving. 

Music in our ears: The science of timbre

A new study offers insight into the neural underpinnings of musical timbre. Researchers have used mathematical models based on experiments in both animals and humans to accurately predict sound source recognition and perceptual timbre judgments by human listeners.

Privacy vs. protection: Study considers how to manage epidemics in information blackouts

When foot-and-mouth disease swept through the British countryside in early 2001, more than 10 million sheep, cattle and pigs were slaughtered to control the disease. Despite the devastation, the disease was contained within ten months in part owing to the availability in that country of finely detailed farm data, which enabled mathematical modelers to make accurate predictions about the spread of...

Country diary: South Uist: Sheep dippers and potato pickers toil in the unseasonably warm weather

South Uist: The strength of the sunshine has brought out the warm herby smell characteristic of this stretch of the machairDown on the machair the temperature is unseasonably high and I'm certainly not envious of the group of crofters who, clad in wellies, waterproof dungarees and rubber gloves, are busily dunking a seemingly endless stream of resigned-looking animals at the sheep dip. The...

NASA investigates the 'FaINT' side of sonic booms

Sonic booms created by aircraft flying faster than the speed of sound certainly aren't known for being faint, but rather for their loud, make-you-jump startle effect for those who experience them. However, sonic booms have a quieter, fainter side, too.

SpaceX transitions to third commercial crew phase

Space Exploration Technologies (SpaceX) has completed its first three performance milestones for NASA's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to lead to the availability of commercial human spaceflight services for government and commercial...

NASA's SAMPEX mission: A space weather warrior

NASA's very first small explorer, the Solar, Anomalous, and Magnetospheric Particle Explorer or SAMPEX, was launched July 3, 1992 to study the zoo of particles and cosmic rays surrounding Earth. Surviving much longer than its expected mission of three years and providing invaluable observations for those who study space weather, the SAMPEX mission is now almost over. In early November, the...
