Specifically, she will try to determine the role of early calcium signaling defects in AD, and, to determine if normalizing this calcium defect can reduce the later symptoms of the disease. Alzheimer's disease is the most prevalent neurodegenerative disease affecting an est...What we can learn from the biggest extinction in the history of Earth
... Earth Sciences, will use one geochemical index to try to understand how climate did change during the end-Permian period. Two other students will examine coral reef structures. The Great Bank of Guizhou contains the fossilized reefs from just before and just after this extinction event. Undergraduate ...UF, French scientists seek test to detect gene doping in athletes
...a research program in place for some years now, to try to develop tests for gene-based doping, said Theodore Friedmann, M.D., head of the agencys panel on genetic doping and director of the gene therapy program at the University of California, San Diego. It sounds futuristic, but experts say its only ...Genetic analysis finds greater threat in frog-killing fungus
...ed would not be affected that badly. We could then try to determine the mechanisms those frogs use to resist the pathogen." The study also found that the sites near Tioga Pass Road contained two similar populations of fungi. Because the lakes are 40 kilometers apart, the evidence is strong that movemen...Disabling a sensory organ prompts female mice to act like male mice
...avenues to explain sexually dimorphic behavior. To try and ferret out its cause, they've looked at everything from the influences of hormones such as testosterone to anatomy, positing that there may be a region of the brain that organizes gender-based behavior. The sensory-controlled neural switch that...Success or failure of antidepressant citalopram predicted by gene variation

After the trial, researchers spelled out the DNA codes contained in 68 genes suspected of being involved in depression, collected from 1,297 of the patients who had participated in STAR*D.

A number of hospitals undergoing renovations have experienced outbreaks, in many cases after the organism contaminated ventilation systems or f...Stem cell therapy rescues motor neurons in ALS model
...though the obvious next step in the research is to try and ferret out the reasons the protected motor neurons are unable to hook up with muscles, Svendsen suggests the work further supports movement toward clinical trials in humans. "We think the cells are safe, and they do increase the survival of the...GI Caramba! Blue tortillas may help dieters and diabetics
People with dieting blues should try swapping white corn tortillas for blue. A recent study suggests that the coloured flatbreads are healthier, especially for diabetics and dieters, Sara Jensen reports in Chemistry & Industry, the magazine of the SCI. Scientists in Mexico, home of t...Report recommends off-site disposal of secondary waste

...ologies, both that give a pretty good off, why not try to combine them together to get a really clear and strong off, said Collins. The first strategy, a repressor protein, sits on DNA like a roadblock, preventing any gene product -- messenger RNA (mRNA) -- from being made. If any mRNA gets past this r...Faster-acting antidepressants closer to becoming a reality

These other compounds also reduced depressive behaviors, suggesting that it may be feasible to develop other fast-acting antidepressants without ketamines side effects.

But perhaps we could use neutrophins, growth-inducing proteins whose synthesis by brain neurons is stimulated by testosterone.
