West Antarctic Ice Shelves Tearing Apart at the Seams

AUSTIN, Texas — A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.

The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or slower ice masses, are fracturing and retreating inland. As that grip continues to loosen, these already-thinning ice shelves will be even less able to hold back grounded ice upstream, according to glaciologists at The University of Texas at Austin’s Institute for Geophysics (UTIG).

Berkeley Lab Study Shows Significantly Higher Potential for Wind Energy in India than Previously Estimated

A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates— about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India’s renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity.

“The main importance of this study, why it’s groundbreaking, is that wind is one of the most cost-effective and mature renewable energy sources commercially available in India, with an installed capacity of 15 GW and rising rapidly,” says Berkeley Lab scientist Amol Phadke, the lead author of the report. “The cost of wind power is now comparable to that from imported coal and natural gas-based plants, and wind can play a significant role in cost effectively addressing energy security and environmental concerns.” (more…)

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.

The technique could lead to affordable personalized medicine, potentially revealing predispositions for afflictions such as cancer, diabetes or addiction. (more…)

*Study Conducted with EXPO Shows Persuasive Elements of User-Generated Product Videos Lift Brand Affinity When Used in Tandem with Professionally-Produced Content*

NEW YORK, NY and RESTON, VA, March 28, 2012 – comScore, Inc., a leader in measuring the digital world, and EXPO, the first consumer network focused on creating and distributing high impact product videos to drive engagement and conversion, today released the results of a study on the synergy of professionally-produced video content and user-generated product videos in marketing campaigns. The study evaluated an actual campaign that included a combination of a professionally-produced “how to” video and a user-generated product video that was created and submitted by an actual product user. The results of the study indicate that professionally-produced video content and user-generated product videos are highly synergistic, driving higher levels of sales effectiveness when used in tandem.

Protein ‘Jailbreak’ Helps Cancer Cells Live

Researchers at Brown University and Hasbro Children’s Hospital have traced the molecular interactions that allow the protein survivin to escape the nucleus of a breast cancer cell and prolong the cell’s life. The study may help in the development of better therapies and prognostics

PROVIDENCE, R.I. [Brown University] — If the fight against breast cancer were a criminal investigation, then the proteins survivin, HDAC6, CBP, and CRM1 would be among the shadier figures. In that vein, a study to be published in the March 30 Journal of Biological Chemistry is the police report that reveals a key moment for keeping cancer cells alive: survivin’s jailbreak from the nucleus, aided and abetted by the other proteins. The research highlights that a protein’s location in a cell affects its impact on disease, and offers clear new leads for the investigation. (more…)
