Research: It's more than just the science
In a newly published paper, a team of researchers from institutions across the country, including Michigan State University, outline not only why it's important to pursue science collaboratively, but how to create and maintain science teams to get better research results.

Sucker-footed fossils broaden the bat map
Today, Madagascar sucker-footed bats live nowhere outside their island home, but new research shows that hasn't always been the case. The discovery of the jawbones of two extinct relatives in northern Egypt suggests the unusual creatures, which evolved sticky footpads to roost on slick surfaces, are primitive members of a group of bats that evolved in Africa and ultimately went on to flourish in South America.

WPI researchers tackle the challenges of putting robots on the shop floor and in our homes
Researchers at Worcester Polytechnic Institute have received awards through the National Science Foundation's National Robotics Initiative to investigate and overcome fundamental challenges involved with robots working alongside people. Dmitry Berenson will develop algorithms that will permit robots to collaborate with people on small-scale manufacturing operations. Sonia Chernova will draw on the experience of thousands of online "teachers" to learn more about how "everyday people" can teach robots to do simple tasks.

New scientific field looks at the big picture
Big data is changing the field of ecology. The shift is dramatic enough to warrant the creation of an entirely new field: macrosystems ecology. "Ecologists can no longer sample and study just one or even a handful of ecosystems," said Patricia Soranno, Michigan State University professor of fisheries and wildlife and macrosystems ecology pioneer.

In the brain the number of neurons in a network may not matter
A study has found that the time it takes neural networks in the brain to make decisions is remarkably stable regardless of size: a finding that could make it easier to achieve the goal of the President's BRAIN Initiative established last spring.

Greenland's fastest glacier reaches record speeds
Jakobshavn Isbræ is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. Researchers from the University of Washington and the German Space Agency measured the dramatic speeds of the fast-flowing glacier in 2012 and 2013. The results are published today in The Cryosphere, an open access journal of the European Geosciences Union.

To calculate long-term conservation pay off, factor in people
Paying people to protect their natural environment is a popular conservation tool around the world – but figure out that return on investment, for both people and nature, is a thorny problem, especially since such efforts typically stretch on for years. Reseachers have developed a new way to evaluate and model the long-term effectiveness of conservation investments.

Lemur lovers sync their scents
Mating pairs of lemurs mirror each other's scent-marking behavior and even start to smell alike after they have reproduced. Matched scents are possibly a way to combine territory defenses or to advertise their relationship status to the rest of their group, according to researchers at the Duke Lemur Center. Couples who haven't had kids yet spend the most time scent-marking and investigating each other's odors.

Rhode Island Hospital researchers have identified components in Clostridium difficile (C. diff) that may lead to new diagnostic tools, and ultimately more timely and effective treatment for this often fatal infection. C. diff is a spore-forming bacterium that causes severe diarrhea and is responsible for 14,000 deaths annually in the US.

What your company can learn from NASA tragedies
BYU business professor Peter Madsen has been researching how NASA recognizes "near-miss" events ever since the Columbia shuttle was destroyed in flight 11 years ago Saturday. A new study coauthored by Madsen finds recognition of near-misses goes up when leaders emphasize project significance and weigh safety over other goals.

Expanding the range of nature's catalysts for industrial applications
"We've learned to make changes in the stability of the protein. But every protein has a limit; there's nothing you can do to make a protein stable at 500 degrees, for example," said Makhatadze. "So can we somehow make it unfold more slowly by modulating the charge-charge interactions? If you can extend that process, it will function at a high temperature for a longer period of time, and that's beneficial."

Dinosaur fossils from China help Penn researchers describe new 'Titan'
A team led by University of Pennsylvania paleontologists has characterized a new dinosaur based on fossil remains found in northwestern China. The species, a plant-eating sauropod named Yongjinglong datangi, roamed during the Early Cretaceous period, more than 100 million years ago. This sauropod belonged to a group known as Titanosauria, members of which were among the largest living creatures to ever walk the earth.

From rivers to landslides: Charting the slopes of sediment transport
The slope of streambeds has dramatic and unexpected effects on sediment transport. Experimental data from the flume lab show that gravity does not facilitate sediment transport in the expected manner. In very steep streambeds with a 22-degree or higher slope, sediment motion begins not with grains skipping and bouncing along the bottom of the streambed, but rather with a complete bed failure in which all the sediment is abruptly sent hurtling downstream as a debris flow.

Puzzling question in bacterial immune system answered
Berkeley researchers have answered a central question about Cas9, an enzyme that plays an essential role in the bacterial immune system and is fast becoming a valuable tool for genetic engineering: How is Cas9 able to precisely discriminate between non-self DNA that must be degraded and self DNA that may be almost identical within genomes that are millions to billions of base pairs long.

Neanderthals' genetic legacy
Remnants of Neanderthal DNA in modern humans are associated with genes affecting type 2 diabetes, Crohn's disease, lupus, biliary cirrhosis and smoking behavior. They also concentrate in genes that influence skin and hair characteristics. At the same time, Neanderthal DNA is conspicuously low in regions of the X chromosome and testes-specific genes.

H.M.'s brain yields new evidence
During his lifetime, Henry G. Molaison (H.M.) was the best-known and possibly the most-studied patient of modern neuroscience. Now, thanks to the postmortem study of his brain, based on histological sectioning and digital three-dimensional construction led by Jacopo Annese, Ph.D., at the University of California, San Diego, scientists around the globe will finally have insight into the neurological basis of the case that defined modern studies of human memory.

Boston University study examines the development of children's prelife reasoning
By examining children's ideas about "prelife," the time before conception, researchers found results which suggest that our bias toward immortality is a part of human intuition that naturally emerges early in life. And the part of us that is eternal, we believe, is not our skills or ability to reason, but rather our hopes, desires and emotions.
