A New Tool to Attack the Mysteries of High-Temperature Superconductivity

Berkeley Lab researchers use an ultrafast laser to better understand high-temperature superconductors

Superconductivity, in which electric current flows without resistance, promises huge energy savings – from low-voltage electric grids with no transmission losses, superefficient motors and generators, and myriad other schemes. But such everyday applications still lie in the future, because conventional superconductivity in metals can’t do the job.

Although they play important roles in science, industry, and medicine, conventional superconductors must be maintained at temperatures a few degrees above absolute zero, which is tricky and expensive. Wider uses will depend on higher-temperature superconductors that can function well above absolute zero. Yet known high-temperature (high-Tc) superconductors are complex materials whose electronic structures, despite decades of work, are still far from clear. (more…)

Where Have All the Hummingbirds Gone?

Glacier lilies and broad-tailed hummingbirds out of sync

The glacier lily as it’s called, is a tall, willowy plant that graces mountain meadows throughout western North America. It flowers early in spring, when the first bumblebees and hummingbirds appear.

Or did.

The lily, a plant that grows best on subalpine slopes, is fast becoming a hothouse flower. In Earth’s warming temperatures, its first blooms appear some 17 days earlier than they did in the 1970s, scientists David Inouye and Amy McKinney of the University of Maryland and colleagues have found.

Majority of Tablet Users Watch Video on their Device, 1 in Every 4 Viewers Pay to Watch

comScore Previews Findings from TabLens™, its Forthcoming Syndicated Tablet Measurement Service

RESTON, VA, June 8, 2012 – comScore, Inc., a leader in measuring the digital world, today released new insights on the U.S. tablet market from comScore TabLens™, its forthcoming monthly syndicated service providing insights into tablet ownership and usage. The report found that tablets have quickly reached a critical mass in the U.S. with 1 in every 4 smartphone owners using tablets during the three-month average period ending April 2012. The study also found that tablet users were nearly three times more likely to watch video on their device compared to smartphone users, with 1 in every 10 tablet users viewing video content almost daily on their device.

“Tablets are one of the most rapidly adopted consumer technologies in history and are poised to fundamentally disrupt the way people engage with the digital world both on-the-go and perhaps most notably, in the home,” said Mark Donovan, comScore SVP of Mobile. “It’s not surprising to see that once consumers get their hands on their first tablet, they are using them for any number of media habits including TV viewing.” (more…)

Exercise and Healthy Eating Make a Difference Even Later in Life

ANN ARBOR, Mich.— Women in their 70s had a longer life expectancy when they exercised and regularly ate fruits and vegetables, a new University of Michigan study found.

“This is the first study to show that the combination of a healthy diet and greater physical activity predict greater survival and that the combination of both positive factors confers lower mortality risk than either factor alone,” said Emily Nicklett, U-M assistant professor of social work.

Nicklett and researchers at The Johns Hopkins University studied the results from 713 women ages 70 to 79 years who participated in the Women’s Health and Aging Studies. (more…)

CU-Boulder Physicists Use Ultrafast Lasers to Create First Tabletop X-Ray Device

An international research team led by the University of Colorado Boulder has generated the first laser-like beams of X-rays from a tabletop device, paving the way for major advances in many fields including medicine, biology and nanotechnology development. (more…)

IBM Smarter Cities Technology Helps NYC Envision Solar Energy Leadership through CUNY Ventures

Innovative Model Aims to Export Solar Market Analysis Tools to the World

New York – 07 Jun 2012: IBM is helping New York City (NYC) become a global leader in urban solar energy market analysis and sustainability through an innovative agreement with CUNY Ventures, a City University of New York (CUNY) Economic Development Corporation entity.

The goal of this effort is to nourish solar adoption by developing the capability to analyze and understand key solar market indicators that can make solar system development more cost competitive. Using IBM’s Intelligent Operations Center (IOC) for Smarter Cities as the backbone, this analytics-based approach will help New York City monitor and analyze solar production and capacity through a virtual control room that will provide a dashboard view of key indicators.

The collaboration is part of ‘Solar Market Analytics, Roadmapping, and Tracking NY’ (SMART NY), a groundbreaking project supported in part by the U.S. Department of Energy (DOE) ‘Rooftop Solar Challenge’, part of the DOE SunShot Initiative which is striving to make solar energy cost-competitive with other forms of energy by the end of the decade.

Too Few Salmon is Far Worse Than Too Many Boats for Killer Whales

Not having enough Chinook salmon to eat stresses out southern resident killer whales in the Pacific Northwest more than having boatloads of whale watchers nearby, according to hormone levels of whales summering in the Salish Sea. (more…)

Yahoo! Launches Shine Latina for Today’s Bicultural, Bilingual Woman

The Leading Website for Women’s Lifestyle Content Adds Latina Spice

SUNNYVALE, Calif. — Yahoo! Inc., the premier digital media company, today unveiled Shine Latina – a home for bicultural Latina lifestyle content, within Yahoo! Shine, a top site for women’s lifestyle content in the U.S. with more than 34 million unique visitors a month*.
