Non-native Plants Show a Greater Response Than Native Wildflowers to Climate Change

COLUMBUS, Ohio – Warming temperatures in Ohio are a key driver behind changes in the state’s landscape, and non-native plant species appear to be responding more strongly than native wildflowers to the changing climate, new research suggests.

This adaptive nature demonstrated by introduced species could serve them well as the climate continues to warm. At the same time, the non-natives’ potential ability to become even more invasive could threaten the survival of native species already under pressure from land-use changes, researchers say. (more…)

Taking Race Out of the Equation in Measuring Women’s Risk of Osteoporosis and Fractures

For women of mixed racial or ethnic backgrounds, a new method for measuring bone health may improve the odds of correctly diagnosing their risk of osteoporosis and bone fractures, according to a UCLA-led study.

Currently, assessing osteoporosis and the risk of fractures from small accidents like falls requires a bone density scan. But because these scans don’t provide other relevant fracture-related information, such as bone size and the amount of force a bone is subjected to during a fall, each patient’s bone density is examined against a national database of people with the same age and race or ethnicity.

Could a Hurricane Ever Strike Southern California?

There’s an old adage (with several variations) that California has four seasons: earthquake, fire, flood and drought. While Californians happily cede the title of Hurricane Capital of America to U.S. East and Gulf coasters, every once in a while, Mother Nature sends a reminder to Southern Californians that they are not completely immune to the whims of tropical cyclones. Typically, this takes the form of rainfall from the remnants of a tropical cyclone in the eastern Pacific, as happened recently when the remnants of Hurricane John brought rain and thunderstorms to parts of Southern California. But could a hurricane ever make landfall in Southern California?

The answer, as it turns out, is yes, and no. While there has never been a documented case of a hurricane making landfall in California, the Golden State has had its share of run-ins and close calls with tropical cyclones. In fact, California has been affected by at least a few tropical cyclones in every decade since 1900. Over that timeframe, three of those storms brought gale-force winds to California: an unnamed California tropical storm in 1939, Kathleen in 1976 and Nora in 1997. But the primary threat from California tropical cyclones isn’t winds or storm surge. It’s rainfall — sometimes torrential — which has led to flooding, damage and, occasionally, casualties. (more…)

Microsoft Employees Raise $1 Billion for Communities Around the World

Microsoft commemorates 30th Employee Giving Campaign with CEO Steve Ballmer and Chairman and Founder Bill Gates.

REDMOND, Wash. — Oct. 18, 2012 — Microsoft Corp. today commemorated its 30th Employee Giving Campaign and announced that U.S. employees raised $1 billion in cash since 1983 for approximately 31,000 nonprofits and community organizations around the world. CEO Steve Ballmer announced the milestone during a special town hall event at the Microsoft Redmond campus, which included Microsoft Chairman Bill Gates and Washington State Gov. Chris Gregoire.

“Today, I’m thrilled to announce that since our Employee Giving Campaign started in 1983, Microsoft employees have donated a total of $1 billion to more than 31,000 nonprofits around the world,” Ballmer said. “I’m incredibly proud of our employees, and this is truly a time to celebrate, not just because we’ve raised a record amount of funds, but also because together with our nonprofit partners, we have impacted and improved the lives of hundreds of millions of people.” (more…)

Researchers Create ‘Nanoflowers’ for Energy Storage, Solar Cells

Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flower holds promise for next-generation energy storage devices and solar cells.

“Creating these GeS nanoflowers is exciting because it gives us a huge surface area in a small amount of space,” says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and co-author of a paper on the research. “This could significantly increase the capacity of lithium-ion batteries, for instance, since the thinner structure with larger surface area can hold more lithium ions. By the same token, this GeS flower structure could lead to increased capacity for supercapacitors, which are also used for energy storage.” (more…)
