Researchers at the University of Copenhagen have found that a protein, known for causing cancer cells to spread around the body, is also one of the molecules that trigger repair processes in the brain. These findings are the subject of a paper, published this week in Nature Communications. They point the way to new avenues of research into degenerative brain diseases like Alzheimer's.
How to repair brain injuries is a fundamental question facing brain researchers. Scientists have been familiar... Continue reading...

Researchers utilized stretchable electronics to create a catheter to make cardiac ablation simpler. (Credit: Image courtesy of Northwestern University) Researchers at the McCormick School of Engineering are part of a team that has used stretchable electronics to create a multipurpose medical catheter that can both monitor heart functions and perform corrections on heart tissue during surgery.
The device marks the first time stretchable electronics have been applied to a surgical process known ... Continue reading...

Scientists have discovered a subpopulation of cells that display cancer stem cell properties and resistance to chemotherapy, and participate in tumor progression. (Credit: © Jezper / Fotolia) Scientists at Mount Sinai School of Medicine have discovered a subpopulation of cells that display cancer stem cell properties and resistance to chemotherapy, and participate in tumor progression. This breakthrough could lead to the development of new tests for early cancer diagnosis, prognostic tests, ... Continue reading...

Concept illustration of the microscale free-surface microfluidic channel as it concentrates vapor molecules that bind to nanoparticles inside a chamber. A laser beam detects the nanoparticles, which amplify a spectral signature of the detected molecules. (Credit: Image courtesy of University of California - Santa Barbara) Portable, accurate, and highly sensitive devices that sniff out vapors from explosives and other substances could become as commonplace as smoke detectors in public places, ...

Scientists at MU have found that treatment with a compound found in grape skins and red wine could increase the chances of a full recovery from all types of prostate cancer, including aggressive tumors. (Credit: Image courtesy of University of Missouri-Columbia) Resveratrol, a compound found commonly in grape skins and red wine, has been shown to have several beneficial effects on human health, including cardiovascular health and stroke prevention. Now, a University of Missouri researcher has... Continue reading...

Whether you are an apple tree or an antelope, survival depends on using your energy efficiently. In a difficult or dangerous situation, the key question is whether exerting effort -- sending out roots in search of nutrients in a drought or running at top speed from a predator -- will be worth the energy.
In a paper published online Nov. 18 inNature, Karl Deisseroth, MD, PhD, a professor of bioengineering and of psychiatry and behavioral sciences at Stanford University, and postdoctoral scholar... Continue reading...

Low levels of vitamin D in people with diabetes appear to encourage cholesterol to build up in arteries, eventually blocking the flow of blood. In mice, immune cells adhering to the wall of a major blood vessel near the heart are loaded with cholesterol (shown in red). (Credit: Bernal-Mizrachi lab) People with diabetes often develop clogged arteries that cause heart disease, and new research at Washington University School of Medicine in St. Louis suggests that low vitamin D levels are to bla...

Researchers from Johns Hopkins and Northwestern universities have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases.
This study, to be published in the Oct. 12 online edition of the journalAdvanced Materials, is also noteworthy because this gene therapy technique does not use a virus to carry DNA into cells. Some gene therapy e... Continue reading...

An experimental diet with carbohydrates eaten mostly at dinner could benefit people suffering from severe and morbid obesity, according to new research at the Hebrew University of Jerusalem.
The diet influences secretion patters of hormones responsible for hunger and satiety, as well as hormones associated with metabolic syndrome. In this way the diet can help dieters persist over the long run, and reduce risk factors for diabetes and cardiovascular disease. The research was carried out by res... Continue reading...

One of the largest studies to look at the effect of induced abortions on a subsequent first birth has found that women who have had three or more abortions have a higher risk of some adverse birth outcomes, such as delivering a baby prematurely and with a low birth weight.
The research, which is published online in Europe's leading reproductive medicine journal Human Reproduction Aug. 29, found that among 300,858 Finnish mothers, 31,083 (10.3%) had had one induced abortion between 1996-2008, 4... Continue reading...
