Duke University researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology. They are exploring whether their glassification technique could bring about protein-based drugs that are cheaper to make and easier to deliver than current techniques which render proteins into freeze dried powders to preserve them. Duke engineer and chemist David Needham describes this glassification process as "molecular...

Given a choice between spending a token to get their absolute favorite food or spending it to have a choice from a buffet of options, capuchin monkeys will opt for variety. In fact, they'll even eat a less-preferred food from that buffet when the favorite food is on it. They choose variety for variety's sake. The choices made by these captive-bred monkeys in an Italian research facility seem to show some innate desire to seek variety, said Dan Ariely, the James B. Duke Professor of psychology...

New research suggests that falling stocks may damage more than just your portfolio. According to new research at Duke University, the downturn of stocks may bring on heart attacks. Researchers found a link between how stock indexes performed and how many heart attacks were treated at a North Carolina hospital shortly after the recession started in December 2007 through July 2009. Results showed that the trend weakened during a second analysis, but researchers took into account different...

Using advanced tools to see the human brain at work, a new generation of marketing experts may be able to test a product's appeal while it is still being designed, according to a new analysis by two researchers at Duke University and Emory University. So-called "neuromarketing" takes the tools of modern brain science, like the functional MRI, and applies them to the somewhat abstract likes and dislikes of customer decision-making. Though this raises the specter of marketers being able to read...

A fossil that was celebrated last year as a possible "missing link" between humans and early primates is actually a forebearer of modern-day lemurs and lorises, according to two papers by scientists at The University of Texas at Austin, Duke University and the University of Chicago. In an article now available online in the Journal of Human Evolution, four scientists present evidence that the 47-million-year-old Darwinius masillae is not a haplorhine primate like humans, apes and monkeys, as...

Thinking flawed that all species react the same to the environment It's a paradox that's puzzled scientists for a half-century. Models clearly show that the coexistence of competing species depends on those species responding differently to the availability of resources. Then why do studies comparing competing tree species draw a blank? Competitors like black gums and red maples have coexisted for millennia in the shaded understories of eastern U.S. forests, yet species-level data offer scant...

If a tiger's feet were built the same way as a mongoose's feet, they'd have to be about the size of a hippo's feet to support the big cat's weight. But they're not. For decades, researchers have been looking at how different-sized legs and feet are put together across the four-legged animal kingdom, but until now they overlooked the "shoes," those soft pads on the bottom of the foot that bear the brunt of the animal's walking and running. New research from scientists in Taiwan and at Duke...

Cultural views of evolution can have important ethical implications, says a Duke University expert on theological and biomedical ethics. Because the popular imagination filters science through cultural assumptions about race, cultural history should be an essential part of biomedical conversations. Amy Laura Hall, associate professor of Christian ethics at Duke University, argues that many popularized ideas about evolution assume that some human groups are more evolved than other human...

New research suggests that the act of voluntarily sharing something with another may not be entirely exclusive to the human experience. A study published in the March 9th issue of Current Biology, a Cell Press publication, observed that bonobos"”a sister species of chimpanzees and, like chimps, our closest living relatives"”consistently chose to actively share their food with others. "It has been suggested that only humans voluntarily share their food," says lead study author...
