UCLA Study First to Image Concussion-Related Abnormal Brain Proteins in Retired NFL Players

Technique may lead to earlier diagnosis, tracking of brain disorders in athletes

Sports-related concussions and mild traumatic brain injuries have grabbed headlines in recent months, as the long-term damage they can cause becomes increasingly evident among both current and former athletes. The Centers for Disease Control and Prevention estimates that millions of these injuries occur each year.

Despite the devastating consequences of traumatic brain injury and the large number of athletes playing contact sports who are at risk, no method has been developed for early detection or tracking of the brain pathology associated with these injuries. (more…)

IBM and The Institute of Bioengineering and Nanotechnology Develop New Antimicrobial Hydrogel to Fight Superbugs and Drug-Resistant Biofilms

Applications range from protective coating to sterilize hospital surfaces and medical equipment or as an injection to more effectively treat patients

SAN JOSE, Calif. – 24 Jan 2013: Researchers from IBM and the Institute of Bioengineering and Nanotechnology revealed today an antimicrobial hydrogel that can break through diseased biofilms and completely eradicate drug-resistant bacteria upon contact. The synthetic hydrogel, which forms spontaneously when heated to body temperature, is the first-ever to be biodegradable, biocompatible and non-toxic, making it an ideal tool to combat serious health hazards facing hospital workers, visitors and patients.

Traditionally used for disinfecting various surfaces, antimicrobials can be found in traditional household items like alcohol and bleach. However, moving from countertops to treating drug resistant skin infections or infectious diseases in the body are proving to be more challenging as conventional antibiotics become less effective and many household surface disinfectants are not suitable for biological applications.

UMass Amherst Cell Biologists Show Molecular Forces Are Key to Proper Cell Division

AMHERST, Mass. – Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology. (more…)

Public Acceptance of Climate Change Affected by Word Usage, Says MU Anthropologist

Better science communication could lead to a more informed American public.

Public acceptance of climate change’s reality may have been influenced by the rate at which words moved from scientific journals into the mainstream, according to anthropologist Michael O’Brien, dean of the College of Arts and Science at the University of Missouri. A recent study of word usage in popular literature by O’Brien and his colleagues documented how the usage of certain words related to climate change has risen and fallen over the past two centuries. Understanding how word usage affects public acceptance of science could lead to better science communication and a more informed public.

“Scientists can learn from this study that the general public shouldn’t be expected to understand technical terms or be convinced by journal papers written in technical jargon,” O’Brien said. “Journalists must explain scientific terms in ways people can understand and thereby ease the movement of those terms into general speech. That can be a slow process. Several words related to climate change diffused into the popular vocabulary over a 30-50 year timeline.” (more…)

Lack of Key Enzyme in the Metabolism of Folic Acid Leads to Birth Defects

AUSTIN, Texas — Researchers at The University of Texas at Austin have discovered that the lack of a critical enzyme in the folic acid metabolic pathway leads to neural tube birth defects in developing embryos.

It has been known for several decades that folic acid supplementation dramatically reduces the incidence of neural tube defects, such as spina bifida and anencephaly, which are among the most common birth defects. In some populations, folic acid supplementation has decreased neural tube defects by as much as 70 percent. (more…)

Golden Algae: They Hunt, They Kill, They Cheat

Cheating is a behavior not limited to humans, animals and plants. Even microscopically small, single-celled algae do it, a team of UA researchers has discovered.

Humans do it, chimpanzees do it, cuckoos do it – cheating to score a free ride is a well-documented behavior by many animals, even plants. But microscopically small, single-celled algae? Yes, they do it too, biologists with the University of Arizona’s department of ecology and evolutionary biology have discovered. (more…)
