 ScienceSaving the single cysteine: New antioxidant system found We've all read studies about the health benefits of having a life partner. The same thing is true at the molecular level, where amino acids known as cysteines are much more vulnerable to damage when single than when paired up with other cysteines.

Biological PsychiatryPossible link studied between childhood abuse and early cellular aging Researchers from Brown University and Butler Hospital have determined that children who suffer physical or emotional abuse may be faced with accelerated cellular aging as adults. The findings are published online in the journal Biological Psychiatry. A print version of the article is also expected.

AnesthesiologySurgery not linked to memory problems in older patients For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study by School of Medicine researchers questions that assumption. In the 575 patients they studied, the investigators did not detect any long-term cognitive declines attributable to surgery.

Cell Host & MicrobeNew culprit for viral infections among elderly -- an overactive immune response Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people. Published in the Nov. 19 Cell Host & Microbe, the study bucks the general belief that declining immune responses are to blame for susceptibility to viral infections. Contact: Karen N. Peart

Journal of Alzheimer's DiseaseNew neuroimaging analysis technique identifies impact of Alzheimer's disease gene in healthy brains Brain imaging can offer a window into risk for diseases such as Alzheimer's disease. A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. The results of this study are published in the November 2009 issue of the Journal of Alzheimer's Disease. Contact: Saskia van Wijngaarden

Investigative Ophthalmology & Visual ScienceStudy finds many people with hemianopia have difficulty detecting pedestrians while driving, advocates for individual testing Schepens Eye Research Institute scientists have found that -- when tested in a driving simulator -- patients with hemianopia have significantly more difficulty detecting pedestrians than normally sighted people. These results, published in the November 2009 issue of Investigative Ophthalmology and Visual Science, fly in the face of some recent on-road studies that have found most people with hemianopia safe to drive.

American Journal of Public HealthPeople entering their 60s may have more disabilities today than in prior generations A new study suggests that people now beginning to enter their 60s -- the Baby Boomer generation -- have more disabilities than their counterparts did in prior generations. The researchers analyzed two sets of data from surveys 10 years apart and found that disabilities among 60- to 69-year-olds had increased between 40 and 70 percent over that period.

Proceedings of the National Academy of SciencesLongevity tied to genes that preserve tips of chromosomes A team led by researchers at Albert Einstein College of Medicine of Yeshiva University has found a clear link between living to 100 and inheriting a hyperactive version of an enzyme that rebuilds telomeres -- the tip ends of chromosomes. The findings appear in the latest issue of the Proceedings of the National Academy of Sciences. Contact: Deirdre Branley

Proceedings of the National Academy of Sciences'Escaped' proteins add to hearing loss in elderly, UF researchers find A multi-institutional team of researchers has identified a protein that is central to processes that cause oxidative damage to cells and lead to age-related hearing loss. The findings help point the way toward a new target for antioxidant therapies. Contact: Czerne M. Reid

Neurobiology of AgingSqueak, squeak -- can you hear me now? What do you get when you cross a mouse with poor hearing and a mouse with even worse hearing? Ironically, a new strain of mice with "golden ears" -- mice that have outstanding hearing as they age. The new mouse hears much like people with "golden ears" -- people who are able to retain great hearing even as they grow older.

HortScienceBreeding better broccoli Plant carotenoids are the most important source of vitamin A in the human diet and are considered to be valuable antioxidants capable of protecting humans from chronic diseases including macular degeneration, cancer and cardiovascular disease. Researchers investigating the carotenoid content of field-grown broccoli discovered that when it comes to breeding broccoli, lutein levels were linked to the plants' genetics; the environment in which the vegetables were grown had little effect on carotenoid production.

Sleep MedicineJava and nighttime jobs don't mix: study Night-shift workers should avoid drinking coffee if they wish to improve their sleep, according to research published in the journal Sleep Medicine. A new study led by Julie Carrier, a Université de Montréal psychology professor and a researcher at the affiliated Hôpital du Sacré-Cœur Sleep Disorders Centre, has found the main byproduct of coffee, caffeine, interferes with sleep and this side-effect worsens as people age.
