Researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered that a naturally-occurring compound can be incorporated into three-dimensional (3-D) printing processes to create medical implants out of non-toxic polymers. The compound is riboflavin, which is better known as vitamin B2.
“This opens the door to a much wider range of biocompatible implant materials, which can be used to develop customized implant designs using 3-D printing technology,” says Dr. Roger Narayan, senior author of a paper describing the work and a professor in the joint biomedical engineering department at NC State and UNC-Chapel Hill.

Scientists expect climate change and warmer oceans to push the fish that people rely on for food and income into new territory. Predictions of where and when species will relocate, however, are based on broad expectations about how animals will move and have often not played out in nature. New research based at Princeton University shows that the trick to more precise forecasts is to follow local temperature changes.
The researchers report in the journal Science the first evidence that sea creatures consistently keep pace with “climate velocity,” or the speed and direction in which changes such as ocean temperature move. They compiled 43 years of data related to the movement of 128 million animals from 360 species living around North America, including commercial staples such as lobster, shrimp and cod. They found that 70 percent of shifts in animals’ depth and 74 percent of changes in latitude correlated with regional-scale fluctuations in ocean temperature. (more…)
On Sites Like eBay, Strangers No Longer Seen as ‘Just Like You’
COLUMBUS, Ohio – An anonymous stranger you encounter on websites like Yelp or Amazon may seem to be just like you, and a potential friend. But a stranger on a site like eBay is a whole different story.
A new study finds that on websites where people compete against each other, assumptions about strangers change.
Previous research has shown that people have a bias toward thinking that strangers they encounter online are probably just like them. (more…)
Washington, DC — A study published in the July 17, issue of the journal PLOS ONE found that more than 80% of tropical forests in Malaysian Borneo have been heavily impacted by logging.(more…)
Part of the 4Afrika Initiative, the program will offer mentorship, training, university-level education and employment opportunities to aspiring African youth.
LAGOS, Nigeria — Aug. 12, 2013 — In recognition of International Youth Day, Microsoft Corp. Monday introduced the 4Afrika Scholarship program, as part of its 4Afrika Initiative, through which it will provide mentorship, leadership and technical training, certification, university-level education, and employment opportunities for promising African students. Mentorship will be provided by Microsoft employees from around the world, and employment opportunities will include internships and both part-time and full-time jobs within Microsoft, as well as with the company’s more than 10,000 partners across Africa.
Through the company’s 4Afrika Initiative and YouthSpark program, Microsoft has committed to helping millions of Africans get critical skills for entrepreneurship and employability. The 4Afrika Scholarship program is one way the company intends to meet that goal, by helping ensure that promising youth have access to the education, resources and skills they need to succeed, regardless of their financial situations. To help redress gender disparity in higher education in Africa, the company is actively encouraging young women to apply. (more…)
Dolphins can recognize their old tank mates’ whistles after being separated for more than 20 years—the longest social memory ever recorded for a non-human species.
The remarkable memory feat is another indication that dolphins have a level of cognitive sophistication comparable to only a few other species, including humans, chimpanzees and elephants. Dolphins’ talent for social recognition may be even more long-lasting than facial recognition among humans, since human faces change over time, but the signature whistle that identifies a dolphin remains stable over many decades.

Like malaria, dengue fever is an infectious disease transmitted by mosquitoes. Unlike malaria, there is no vaccine for it. As many as 100 million people contract dengue each year, but MSU researcher Zhiyong Xi is working to change that.
Among the estimated 2.5 billion people at risk for dengue, more than 70 percent live in Asia Pacific countries, which spurred Xi to establish a collaborative research institute at Sun Yat-sen University in Guangzhou, China. (more…)
Brown’s growing programs in brain science and engineering come together in the lab of Diane Hoffman-Kim. In a recent paper, her group employed techniques ranging from semiconductor-style circuit patterning to rat cell culture to optimize the growth of nerve cells for applications such as reconstructive surgery.
PROVIDENCE, R.I. [Brown University] — Two wrongs don’t make a right, they say, but here’s how one tangle can straighten out another.
Diane Hoffman-Kim, associate professor of medicine in the Department of Molecular Pharmacology, Physiology, and Biotechnology, is an affiliate of both Brown’s Center for Biomedical Engineering and the Brown Institute for Brain Science. Every thread of expertise woven through those multidisciplinary titles mattered in the Hoffman-Kim lab’s most recent paper, led by graduate student Cristina Lopez-Fagundo. (more…)
