Ethnic segregation in nations straddling the world’s highest terrains may be reinforced by the biological tolerance different peoples have to altitude, according to one of the first studies to examine the effect of elevation on ethnic demographics.

Research from Princeton University published in the journal Applied Geography suggests that people native to low-lying areas can be naturally barred from regions such as the Tibetan Plateau, the Andes or the Himalayas by altitude sickness, which is caused by low oxygen concentration in the air and can be life-threatening. As a result, the homogeny of the local population can increase with elevation. In nations shared by people of high- and lowland extractions, this separation can potentially increase ethnic tension.

Breaking Dengue Fever

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…)

Tactics of new Middle East virus suggest treating by altering lung cells’ response to infection

A new virus that causes severe breathing distress and kidney failure elicits a distinctive airway cell response to allow it to multiply. Scientists studying the Human Coronavirus-Erasmus Medical Center, which first appeared April 2012 in the Middle East, have discovered helpful details about its stronghold tactics.

Their findings predict that certain currently available compounds might treat the infection. These could act not by killing the virus directly but by keeping lung cells from being forced to create a hospitable environment for the virus to reproduce. The researchers caution that their lab and computer predictions would need to be tested to see if the drugs work clinically. (more…)

How the turtle got its shell

The turtle has been in no rush to give up the secret of its shell — but after two centuries of close study, scientists are filling in the story of a structure unique in the history of life.

New research led by Tyler Lyson of Yale University and the Smithsonian Institution pushes back the origins of the turtle shell by about 40 million years, linking it to Eunotosaurus, a 260-million-year-old fossil reptile from South Africa. The work strengthens the fossil record and bolsters an existing theory about shell development while providing new details about its precise evolutionary pathway. (more…)

Dedicated, passionate and energetic, M.D./Ph.D. student Angel Byrd has earned many accolades and research opportunities. But she only recently won a young scientist’s most coveted prize: publication as lead author of a paper highly esteemed by her colleagues.

Well on her way to fulfilling her dreams both in research and medicine, Brown University M.D./Ph.D. student Angel Byrd nevertheless had recently begun to define herself by what was missing, said her adviser, Dr. Jonathan Reichner, associate professor of surgery (research) at Rhode Island Hospital. She still wasn’t a published author.

For years she had dedicated herself to studying how immune system cells capture invading fungal pathogens. Like those cells, called neutrophils, she had seized on seemingly every opportunity that had come her way. (more…)

Professor, author Robertson discusses innovation evolution at Lego

When you hear Lego, if all you think about are shiny, plastic bricks and toys, think again. From a toy concept brought to life by a carpenter to tales of failed innovation truths that mirrored a Greek tragedy, the Lego story is about innovation and evolution, David Robertson told attendees at last week’s Chaplin Tyler Executive Leadership series lecture.

Robertson, professor of practice at the Wharton School at the University of Pennsylvania, presented “Rebuilding Lego” to 80 students, faculty, staff and community members on the University of Delaware’s Newark campus. (more…)

Red Hat, SUSE, IBM Collaborate to Accelerate Enterprise Big Data, Cloud, Mobile and Social Computing in China

BEIJING, China – 14 May 2013: At a press conference in Beijing today, IBM further extended its reach into China with the opening of the first Linux innovation center for Power Systems clients and business partners. The Power Systems Linux Center, located inside IBM’s China Systems Center, will make it simpler for software developers to build and deploy new applications for big data, cloud, mobile and social business computing on open technology building blocks using Linux and the latest IBM POWER 7+ processor technology.

With today’s news, IBM is announcing a new collaboration with Red Hat and SUSE to meet increasing demand from businesses in China for optimized and pre-integrated computing systems running enterprise applications on Linux. The companies will use the new center to help drive more Linux-based solutions in the marketplace and accelerate Linux adoption on Power Systems. The center is open to clients, business partners, academics, and students across the nation. Skills resources include: (more…)

High-speed rail study finds that remote cities benefit from connection to global hubs

Bullet trains fuel real-estate booms, improve quality of life and create other unintended consequences by sharply reducing commute times from smaller cities to large megacities, economists from UCLA and China’s Tsinghua University observed in a new study in China. A similar dynamic, they said, could play out as California builds its own high-speed rail system.

Because high-speed rail effectively brings cities closer together by reducing travel times, it allows people to enjoy many of the benefits of big cities while living in “second-tier” cities far from the pollution and congestion. By making second-tier cities attractive to those who would otherwise flock to global hubs, bullet trains could act as a safety valve for crowded megacities in the developing world and ease the effects of overpopulation, the study authors report.
