Tigers Take the Night Shift to Coexist with People

EAST LANSING, Mich.­­ – Tigers aren’t known for being accommodating, but a new study in the Proceedings of the National Academy of Sciences indicates that the carnivores in Nepal are taking the night shift to better coexist with humans.

The revelation that tigers and people are sharing exactly the same space – the same roads and trails – of Chitwan National Park flies in the face of long-held convictions in conservation circles. It also underscores how successful conservation efforts need sciences that takes into account both nature and humans.

“As our planet becomes more crowded, we need to find creative solutions that consider both human and natural systems,” said Jianguo “Jack” Liu, the director of the Center for Systems Integration and Sustainability at Michigan State University. “Sustainability can be achieved if we have a good understanding of the complicated connections between both worlds. We’ve found something very interesting is happening in Nepal that holds promise for both humans and nature to thrive.” (more…)

African-American Males Most Likely to Lose Academic Scholarships, MU Study Finds

MU researcher recommends a “holistic” approach to student scholarship retention

COLUMBIA, Mo. ­— College student retention and low graduation rates are the most significant problems associated with state-provided financial aid. Now, a University of Missouri researcher has found that African-American males are the most likely to lose state lottery-funded scholarships with academic stipulations. Charles Menifield, a professor in the Truman School of Public Affairs at MU, found that more than 50 percent of African-American males lost state-funded scholarships over the course of a four-year academic career.

“Race turns out to be one of the best predictors of scholarship retention rates,” Menifield said. “This research strongly suggests that colleges and universities that desire to maintain diversity should at minimum target minority students, particularly African-American males, and determine how best to improve academic success.” (more…)

The Flying Swords of Dragon Gate

Synopsis

Three years after the disappearance of the enigmatic innkeeper Jade and the massive fire that consumed the Inn, a new Dragon Inn has risen from the ashes, staffed by a band of marauders. Masquerading as law-abiding citizens by day, they use the cover of night to continue their true calling as fortune hunters. (more…)

NASA, Texas Astronomers Find First Multi-Planet System Around a Binary Star

FORT DAVIS, Texas — NASA’s Kepler mission has found the first multi-planet solar system orbiting a binary star, characterized in large part by University of Texas at Austin astronomers using two telescopes at the university’s McDonald Observatory in West Texas. The finding, which proves that whole planetary systems can form in a disk around a binary star, is published in today’s issue of the journal Science.

“It’s Tatooine, right?” said McDonald Observatory astronomer Michael Endl. “But this was not shown in Star Wars,” he said, referring to the periodic changes in the amount of daylight falling on a planet with two suns. Measurements of the star’s orbits showed that daylight on the planets would vary by a large margin over the 7.4-Earth-day period as the two stars completed their mutual orbits, each moving closer to, then farther from, the planets (which are themselves moving).

Researchers Develop New, Less Expensive Nanolithography Technique

Researchers from North Carolina State University have developed a new nanolithography technique that is less expensive than other approaches and can be used to create technologies with biomedical applications.

“Among other things, this type of lithography can be used to manufacture chips for use in biological sensors that can identify target molecules, such as proteins or genetic material associated with specific medical conditions,” says Dr. Albena Ivanisevic, co-author of a paper describing the research. Ivanisevic is an associate professor of materials science and engineering at NC State and associate professor of the joint biomedical engineering program at NC State and the University of North Carolina at Chapel Hill. Nanolithography is a way of printing patterns at the nanoscale. (more…)

Smartphone App Can Track Objects On the Battlefield as Well as On the Sports Field, Says MU Researcher

COLUMBIA, Mo. — University of Missouri researchers have developed new software using smartphones’ GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects. The software could eventually allow smartphone-armed soldiers to target the location of their enemies. On the home front, the software could be used by everyone, including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.

“The great advantage of a smartphone is that it provides so many tools in a single, readily available, relatively inexpensive package,” said Qia Wang, a doctoral student in MU’s College of Engineering who led the development of the software. “For example, on the battlefield, a soldier needs a rangefinder, compass, GPS and other tools to do reconnaissance before calling in an air strike. With our software, the soldier can have all those instruments in one device that can be purchased off the shelf. When that soldier returns from war, she can use the same software to protect her family by clocking a speeder near her children’s school and catching the culprit on video.” (more…)

Finding Faults

Delaware Geological Survey discovers evidence of past earthquakes

Delaware Geological Survey (DGS) scientists have uncovered hard proof of faults in northern Delaware, indicating the occurrence of earthquakes millions of years ago.

The geologic evidence turned up in sediment samples removed during a well-drilling project this summer from depths ranging 137 to 251 feet down in Smyrna and the Woodland Beach Wildlife Area.

“People have postulated that there are faults in this area,” DGS Senior Scientist Scott Andres said. “Now we have evidence of it.” (more…)

Microbes Help Hyenas Communicate via Scent

EAST LANSING, Mich. — Bacteria in hyenas’ scent glands may be the key controllers of communication.

The results, featured in the current issue of Scientific Reports, show a clear relationship between the diversity of hyena clans and the distinct microbial communities that reside in their scent glands, said Kevin Theis, the paper’s lead author and Michigan State University postdoctoral researcher.

“A critical component of every animal’s behavioral repertoire is an effective communication system,” said Theis, who co-authored the study with Kay Holekamp, MSU zoologist. “It is possible that without their bacteria, many animals couldn’t ‘say’ much at all.” (more…)
