High-Fiber Salad Bar May Help Lagomorphs Survive Climate Change

In some mountain ranges, Earth’s warming climate is driving rabbit relatives known as pikas to higher elevations or wiping them out. But University of Utah biologists discovered that roly-poly pikas living in rockslides near sea level in Oregon can survive hot weather by eating more moss than any other mammal.

“Our work shows pikas can eat unusual foods like moss to persist in strange environments,” says biology professor Denise Dearing, senior author of the new study, published online on Dec. 18, 2013 in the February 2014 issue of Journal of Mammalogy. “It suggests that they may be more resistant to climate change than we thought.” (more…)

Study asks: Is a ‘better world’ possible?

For years, policymakers have attempted to create communities where a diverse group of residents not only live close to one other but also interact freely – in other words, neighborhoods that are both integrated and socially cohesive.

But that might be a lost cause, a Michigan State University sociologist argues in a new study. (more…)

Maths predicts rise and fall of empires

Researchers have developed a new mathematical model that accurately describes the evolution of ancient empires.

The computer model can predict with 65% accuracy where and when the largest complex societies arose in human history.

The research, which suggests that intense warfare is the evolutionary driver of large complex societies, is published in the journal Proceedings of the National Academy of Sciences (PNAS). It was carried out by researchers from the University of Exeter in collaboration with University of Connecticut and the National Institute for Mathematical and Biological Synthesis (NIMBioS) in the US.

Protecting 17 Percent of Earth’s Land May Preserve 67 Percent of Its Plant Species

Protecting key regions that comprise just 17 percent of Earth’s land may help preserve more than two-thirds of its plant species, according to a new study by an international team of scientists, including a biologist from North Carolina State University.

The researchers from Duke University, NC State and Microsoft Research used computer algorithms to identify the smallest set of regions worldwide that could contain the largest numbers of plant species. They published their findings in the journal Science. (more…)

Designing a culturally enlightened experience for the car of the future

Microsoft’s Windows Embedded Automotive team is creating automotive solutions that meet the needs of drivers and passengers in Brazil, Beijing and points in between.

REDMOND, Wash. — June 12, 2013 — Nothing epitomizes the American car experience like the road trip. For many Americans, the image of a two-lane highway stretching toward the horizon evokes a certain sense of adventure and longing for the open road, to pack your bags and head out with no itinerary or timeline. The opposite is true in Asia, where the adventure stems more from the perpetual traffic jams and unpredictable driver behavior in mega-cities like Bangkok, Beijing and Seoul. (more…)

Deep in Texas, a plant-eating feathered dinosaur reemerges

A recently identified feathered dinosaur found deep in West Texas reinforces an emerging view that creatures like it were more diverse and widespread in North America than previously thought, according to a new study.

The species — a turkey-sized herbivore called Leptorhynchos gaddisi — belongs to a broader group of bird-like dinosaurs characterized by toothless beaks and long, slender claws, said researchers, who analyzed fossils found near Big Bend National Park at a site dating to about 75 million years ago.

Research Finds Invasive Kudzu Bugs May Pose Greater Threat Than Previously Thought

The invasive kudzu bug has the potential to be a major agricultural pest, causing significant damage to economically important soybean crops. Conventional wisdom has held that the insect pests will be limited to areas in the southern United States, but new research from North Carolina State University shows that they may be able to expand into other parts of the country.

Kudzu bugs (Megacopta cribraria) are native to Asia, and were first detected in the U.S. in Georgia in 2009. They have since expanded their territory as far north as Virginia. The bugs have an interesting life cycle, which has been thought to be a limiting factor on far they can spread. (more…)

Global Warming will Open Unexpected New Shipping Routes in Arctic, UCLA Researchers Find

Shipping lanes through the Arctic Ocean won’t put the Suez and Panama canals out of business anytime soon, but global warming will make these frigid routes much more accessible than ever imagined by melting an unprecedented amount of sea ice during the late summer, new UCLA research shows.

“The development is both exciting from an economic development point of view and worrisome in terms of safety, both for the Arctic environment and for the ships themselves,” said lead researcher Laurence C. Smith, a professor of geography at UCLA. (more…)
