Light pollution is often associated with negative effects on wildlife. Now, ecologists have found that by mimicking a perpetual full moon, the gas flares and electrical lighting along Scotland’s Forth estuary are helping shorebirds stock up on more food during the winter to fuel their spring migration.

The research is the first to use night-time light data from US military satellites to study animal behaviour.

Coasts and estuaries are among the most rapidly developing areas on Earth. Night-time satellite images of the planet show that except Antarctica, continents are ringed with halos of brightly-lit human development. But coasts are also key wildlife sites. Every year, millions of waterbirds arrive from the Arctic to overwinter on UK coasts, yet scientists remain largely in the dark about how these birds respond to the bright lights of coastal cities and industry.

People are able to detect, within a split second, if a hurtful action they are witnessing is intentional or accidental, new research on the brain at the University of Chicago shows.

The study is the first to explain how the brain is hard-wired to recognize when another person is being intentionally harmed. It also provides new insights into how such recognition is connected with emotion and morality, said lead author Jean Decety, the Irving B. Harris Professor of Psychology and Psychiatry at UChicago.

Anti-Hypertensive Drugs Linked to Increased Risk of Hip Fracture

TORONTO, ON – Elderly people taking anti-hypertensive drugs are at a 43 per cent increased risk of having a hip fracture in the first 45 days of treatment, according to research conducted by family medicine Assistant Professor Dr. Debra Butt. A member of the Department of Family and Community Medicine at the University of Toronto and a family physician affiliated with The Scarborough Hospital, Dr. Butt’s study was published on November 19, 2012 in Archives of Internal Medicine. The study examined data from health care administrative databases in Ontario, looking at records from 2000 to 2009 for community-dwelling hypertensive patients with a mean age of 80.8 years.

There are serious consequences to a hip fracture for the elderly. In the first year of a hip fracture there is a higher mortality rate than is seen for many chronic diseases. Those who recover often lose their independence due to reduced mobility, which can result in depression and overall decreased quality of life. (more…)

Sandy’s Underwater Sandscapes

UD researchers studying ‘fingerprint’ left on seafloor by Hurricane Sandy

Beneath the 20-foot waves that crested off Delaware’s coast during Hurricane Sandy, thrashing waters reshaped the floor of the ocean, churning up fine sand and digging deep ripples into the seabed. Fish, crustaceans and other marine life were blasted with sand as the storm sculpted new surfaces underwater.

UD scientists cued up their instruments to document the offshore conditions before, during and after Sandy’s arrival to scrutinize the differences and better predict the environmental impact of future storms. (more…)

Preschoolers’ Counting Abilities Relate to Future Math Performance, MU Researcher Says

Counting, in addition to reciting, should be emphasized in early childhood education to establish foundation for future academic success

COLUMBIA, Mo. – Along with reciting the days of the week and the alphabet, adults often practice reciting numbers with young children. Now, new research from the University of Missouri suggests reciting numbers is not enough to prepare children for math success in elementary school. The research indicates that counting, which requires assigning numerical values to objects in chronological order, is more important for helping preschoolers acquire math skills.

“Reciting means saying the numbers from memory in chronological order, whereas counting involves understanding that each item in the set is counted once and that the last number stated is the amount for the entire set,” said Louis Manfra, an assistant professor in MU’s Department of Human Development and Family Studies. “When children are just reciting, they’re basically repeating what seems like a memorized sentence. When they’re counting, they’re performing a more cognitive activity in which they’re associating a one-to-one correspondence with the object and the number to represent a quantity.” (more…)

IBM Helps Organizations Address Growing Mobile Computing Opportunity

New software and services enable businesses to create and enhance mobile strategies

ARMONK, N.Y. – 09 Nov 2012: IBM today unveiled a suite of new software and services that enables global organizations to build a comprehensive mobile computing strategy – from securing and managing devices, to creating mobile applications and analyzing data. These new offerings are part of a move by IBM to capitalize on the growing market opportunity for mobile that is expected to drive $130B in revenue for the IT industry by 2015, according to a recent study.[i]

As organizations increasingly view mobile computing as the next platform to conduct business, the market is evolving beyond just the device. Business leaders including the chief information officers (CIOs) and increasingly chief marketing officers (CMOs) of global organizations such as airlines, retailers, governments and healthcare providers are among the businesses turning to IBM to ensure mobile services and solutions are readily available to constituents and in full compliance with IT strategies. They need solutions that can be applied across any mobile environment and device — whether a laptop, smartphone or tablet — and can provide an underlying IT infrastructure that is always available, secure, effectively manages data, and integrates both front and back-end systems.

Changing Climate, Not Tourism, Seems to Be Driving Decline in Chinstrap-Penguin Populations

High-resolution satellite imagery aids in study

The breeding population of chinstrap penguins has declined significantly as temperatures have rapidly warmed on the Antarctic Peninsula, according to researchers funded in part by the National Science Foundation (NSF).

The study indicates that changing climatic conditions, rather than the impact of tourism, have had the greatest effect on the chinstrap population.

Ron Naveen, founder of a nonprofit science and conservation organization, Oceanites, Inc., of Chevy Chase, Md., documented the decline in a paper published in the journal Polar Biology. Naveen and coauthor Heather Lynch, of Stony Brook University, are researchers with the Antarctic Site Inventory (ASI). (more…)

PASADENA, Calif. – A new analysis led by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil. The maps produced from the research will be particularly useful in evaluating how much carbon dioxide Earth’s ecosystems may be able to soak up as greenhouse gas levels increase.

A research team led by JPL research scientist Josh Fisher used 19 years of data from NASA, National Oceanic and Atmospheric Administration and international satellites to assess the maximum possible growth of vegetation all over the world based upon available water and light conditions. The scientists then cross-compared that potential maximum with observed vegetation productivity as measured by satellites. This is the first time such an analysis has been conducted. (more…)
