How to Access Wikipedia During Its SOPA Protest (LiveScience.com)
LiveScience.com - Wikipedia plans to take its English-language site offline Wednesday (Jan. 18) to protest SOPA and PIPA, anti-piracy laws proposed by members of U.S. Congress that Wikipedia administrators say "would be devastating to the free and open web." -

Rare Pictures: Scott's South Pole Expedition, 100 Years Later
A century after British explorer Robert Scott reached the South Pole, "incredibly rich," rarely seen pictures give an inside look at the ill-fated expedition. -

'Thar She Blows!' NASA Designing a Comet Harpoon
A giant harpoon is being developed to be deployed from a hovering spacecraft and take a sample from a moving comet. -

Green Blog: 32,100 and Counting: New Yorkers Speak Out on Fracking
Many boxes of comments on the prospect of horizontal hydraulic fracturing remain to be counted, state environmental officials say.
-
21:00LiveScience.com - Equipped with tiny sensors, insects could scout out buildings filled with noxious chemicals, check under rubble after an earthquake and go places no human spy ever could. In a first step toward making these technologically enhanced insects a reality, scientists have devised a way to power bug-robot hybrids by tapping into their own metabolism.

New gene discovery unlocks mystery to epilepsy in infants
Researchers have come a step closer to unlocking a mystery that causes epileptic seizures in babies. Benign familial infantile epilepsy has been recognized for some time as infantile seizures, without fever, that run in families but the cause has so far eluded researchers. However, clinical researchers have now discovered a gene.

20:52Scientists have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers.
-
20:51Researchers have discovered a key amino acid essential for human nutrition is also an effective insecticide against caterpillars that threaten the citrus industry.
-
20:51For centuries, gossip has been dismissed as salacious, idle chatter that can damage reputations and erode trust. But a new study suggests rumor-mongering can have positive outcomes such as helping us police bad behavior, prevent exploitation and lower stress.

20:51Nitrogen is both an essential nutrient and a pollutant, a byproduct of fossil fuel combustion and a fertilizer that feeds billions, a benefit and a hazard, depending on form, location, and quantity. Agriculture, industry and transportation have spread nitrogen liberally around the planet, say scientists with complex and interrelated consequences for human and ecological health.

20:50Scientists have documented increased cerebral activation in patients with multiple sclerosis following memory retraining using modified Story Memory Technique. This study is the first to demonstrate that behavioral interventions can have a positive effect on brain function in MS, an important step in validating the clinical utility of cognitive rehabilitation.

CSI Oxford: behind the scenes at Britain's top forensic lab
-
20:43For the first time ever, stem cells from umbilical cords have been converted into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases.
-
20:43More than 500 million years ago, single-celled organisms on the Earth's surface began forming multicellular clusters that ultimately became plants and animals. Just how that happened is a question that has eluded evolutionary biologists.
-
20:42A natural enzyme derived from human blood plasma showed potential in significantly reducing the effects of graft-vs.-host disease, a common and deadly side effect of lifesaving bone marrow transplants.
-
20:42Whether it's investing in stocks, bungee jumping or public speaking, why do we often plan to take risks but then "chicken out" when the moment of truth arrives? Scientists argue that this "illusion of courage" is one example of an "empathy gap" -- that is, our inability to imagine how we will behave in future emotional situations.
-
20:40Researchers have identified the critical early cellular and molecular events that give rise to a type of esophageal cancer called esophageal adenocarcinoma, the fastest-rising solid tumor in the United States. The findings challenge conventional wisdom regarding the origin and development of this deadly cancer and its precursor lesion, Barrett's esophagus, and highlight possible targets for new clinical therapies.
-
20:37In the future it should be possible to produce the best anti-malaria drug, artemisinin, more economically and in sufficient volumes for all patients.
-
20:37New research shows that a warmer climate will have quite different consequences for plant species in the Arctic. While most species are expected to lose part of their current habitat, the genetic consequences will differ markedly among species. The research results will have major impact on future conservation efforts.

20:35How liquid can a fluid be? This is a question particle physicists have been working on. The “most perfect liquid” is nothing like water, but the extremely hot quark-gluon-plasma which is produced in heavy-ion collisions at the Large Hadron Collider at CERN. New theoretical results show that this quark-gluon plasma could be even less viscous than was deemed possible by previous theories.

A novel strategy to reduce farm runoff will be tested starting in Minnesota
Minnesota will be the nation's first test site for a novel federal program designed to stem the flow of agricultural pollution that is strangling some of the country's great waterways, including the Chesapeake Bay, the Gulf of Mexico and the Mississippi River. -
20:24Doctors at the Peter Munk Cardiac Centre today performed a minimally invasive surgical procedure to treat high blood pressure, called renal denervation, for the first time in Canada. The procedure can significantly reduce high blood pressure in patients who cannot effectively treat their hypertension through drugs. These patients, numbering approximately 250,000 Canadians, have to endure an especially high risk of heart attacks and stroke, which continues to kill thousands of Canadians every year.

20:24For centuries, gossip has been dismissed as salacious, idle chatter that can damage reputations and erode trust. But a new study from the University of California, Berkeley, suggests rumor-mongering can have positive outcomes such as helping us police bad behavior, prevent exploitation and lower stress.
