Study of body size, feeding rates has implications for ecosystems, food supply
How can blue whales, the largest animals on the planet, survive by feeding on krill, shrimp-like creatures that are the size of a penny? According to UCLA life scientists, it’s all a matter of dimensions. (more…)
A new study combining the latest archaeological evidence with state-of-the-art geoscience technologies provides evidence that climate change was a key ingredient in the collapse of the great Indus or Harappan Civilization almost 4000 years ago. The study also resolves a long-standing debate over the source and fate of the Sarasvati, the sacred river of Hindu mythology.
Once extending more than 1 million square kilometers across the plains of the Indus River from the Arabian Sea to the Ganges, over what is now Pakistan, northwest India and eastern Afghanistan, the Indus civilization was the largest—but least known—of the first great urban cultures that also included Egypt and Mesopotamia. Like their contemporaries, the Harappans, named for one of their largest cities, lived next to rivers owing their livelihoods to the fertility of annually watered lands. (more…)
In celebration of new search experience, Bing launches the Bing Summer of Doing with DoSomething.org.
REDMOND, Wash. — June 1, 2012 — Do you ever feel like you’re spending too much time searching and not enough time doing? If so, you’re not alone. According to a recent survey conducted by Bing and Impulse Research, nearly 75 percent of people spend more time than they would like searching for information online. Time wasted searching is a thing of the past with the new Bing design, which brings together information from the Web, experts and enthusiasts, and your friends to help you do more — available today at https://www.bing.com.
Only Bing brings together the best search with people from social networks, including Facebook and Twitter. In celebration of this new search experience, Bing is joining forces with DoSomething.org to launch the Bing Summer of Doing, designed to inspire people to do amazing things, including giving back to their communities.

Ah, June. It marks the end of school, the start of summer…and the official start of the 2012 Atlantic hurricane season, which got off to an early start in May with the formation of Tropical Storms Alberto and Beryl. National Oceanic and Atmospheric Administration forecasters are calling for a near-normal hurricane season this year. But whether the season turns out to be wild or wimpy, understanding what makes these ferocious storms form and rapidly intensify is a continuing area of scientific research, and is the focus of the NASA-led Hurricane and Severe Storm Sentinel (HS3) airborne mission that kicks off this summer.
Beginning in late August through early October and continuing for the next several years during the Atlantic hurricane season, NASA will dispatch two unmanned aircraft equipped with specialized instruments high above tropical cyclones in the Atlantic Ocean basin. These “severe storm sentinels” will investigate the processes that underlie hurricane formation and intensity change. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., will join several other NASA centers and numerous federal and university partners in the HS3 mission. (more…)
Street lighting is transforming communities of insects and other invertebrates, according to research by the University of Exeter.
Published in the journal Biology Letters, the study shows for the first time that the balance of different species living together is being radically altered as a result of light pollution in our towns and cities.
Believed to be increasing by six per cent a year globally, artificial lighting is already known to affect individual organisms, but this is the first time that its impact on whole communities has been investigated.
This study shows that groups of invertebrates living near to artificial lights include more predators and scavengers. This could be impacting on the survival rates of different species, having a knock-on effect on birds and mammals that rely on these species for food. The effects could be affecting entire ecosystems and even humans. (more…)
Berkeley Lab Researchers Observations of Nanorod Crystal Growth Points Way to Next Generation Energy Devices
In the growth of crystals, do nanoparticles act as “artificial atoms” forming molecular-type building blocks that can assemble into complex structures? This is the contention of a major but controversial theory to explain nanocrystal growth. A study by researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) may resolve the controversy and point the way to energy devices of the future.
Led by Haimei Zheng, a staff scientist in Berkeley Lab’s Materials Sciences Division, the researchers used a combination of transmission electron microscopy and advanced liquid cell handling techniques to carry out real-time observations of the growth of nanorods from nanoparticles of platinum and iron. Their observations support the theory of nanoparticles acting like artificial atoms during crystal growth. (more…)
You know, I never thought I wanted kids. My little brother is seven years younger than I am. My mother worked full-time and my father was mostly absent, so the child-rearing duties frequently fell to me. I was also the oldest of the cousins, who, since their parents didn’t have money for childcare, also ended up in my lap. Oh, I’m not saying I was left alone with them at the tender age of eight or so. My grandmother watched us all, taking us from house to house as she worked as a maid.
So, my grandmother worked, and I watched the kids during the summer and after school. (more…)
UK Has Highest Penetration of Smartphone Map Users in EU5
LONDON, UK, 31 May 2012 – comScore, Inc., a leader in measuring the digital world, today released an overview of mobile and computer usage of 
Maps across the five leading European markets (France, Germany, Italy, Spain and the United Kingdom) using the comScore MobiLens and comScore MMX services. The study showed that 35.0 percent of smartphone users in EU5 reported accessing maps via their device in March 2012, compared to 49.6 percent of the internet audience accessing Maps sites on their computers. Across EU5 markets, the smartphone Map audience increased 55 percent over the past year while map access via computer grew just 8 percent.
“Smartphones are quickly becoming the primary platform for on-the-go services such as maps and navigation. With apps such as Google Maps coming pre-installed on many phones it’s becoming second nature for many of us to rely on the smart device in our pocket to show us the way. The days of checking routes in advance and printing maps to take with us will soon be in our rear view mirror,” said Hesham Al-Jehani, European mobile product manager at comScore. (more…)
