Mice and monkeys don’t develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates.
University of Washington bioengineers have developed the first structure to grow small human blood vessels, creating a 3-D test bed that offers a better way to study disease, test drugs and perhaps someday grow human tissues for transplant.
EAST LANSING, Mich. — Married people may be happier in the long run than those who aren’t married, according to new research by Michigan State University scientists.
Their study, online in the Journal of Research in Personality, finds that although matrimony does not make people happier than they were when they were single, it appears to protect against normal declines in happiness during adulthood.
“Our study suggests that people on average are happier than they would have been if they didn’t get married,” said Stevie C.Y. Yap, a researcher in MSU’s Department of Psychology. (more…)
Berkeley Lab scientists help paint a more complicated picture of the devastating disease
For the past five years, volunteers from the City of Berkeley and surrounding areas have come to Lawrence Berkeley National Laboratory to participate in an ongoing study that’s changing what scientists know about Alzheimer’s disease.
The volunteers, most over the age of 70, undergo what can best be described as a brain checkup. They’re asked to solve puzzles and memorize lists of words. Magnetic resonance imaging (MRI) scans image the structure of their brains in exquisite detail. Functional MRI scans allow scientists to watch portions of their brains light up as they form memories. And Positron emission tomography (PET) scans measure any accumulation of beta-amyloid, a destructive protein that’s a hallmark of Alzheimer’s. (more…)
As malware threats expand into new domains and increasingly focus on industrial espionage, Georgia Tech researchers are launching a new weapon to help battle the threats: a malware intelligence system that will help corporate and government security officials share information about the attacks they are fighting.
Known as Titan, the system will be at the center of a security community that will help create safety in numbers as companies large and small add their threat data to a knowledge base that will be shared with all participants. Operated by security specialists at the Georgia Tech Research Institute (GTRI), the system builds on a threat analysis foundation – including a malware repository that analyzes and classifies an average of 100,000 pieces of malicious code each day.
“As a university, Georgia Tech is uniquely positioned to take this white hat role in between industry and government,” said Andrew Howard, a GTRI research scientist who is part of the Titan project. “We want to bring communities together to break down the walls between industry and government to provide a trusted, sharing platform.” (more…)
