DNA repair proteins monitored at double-strand break

...adiation. It could also suggest new strategies for enhancing repair of double-stranded DNA caused by radiation, natural oxidants in food or the body and other toxins that can cause disease and aging. "Prior to this work, there was no practical and efficient way to find and study the DNA repair proteins that...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...is becoming used as a popular commercial style for enhancing emotion. Brian Monson of the University of Arizona ( bbmonson@email.arizona.edu ) will discuss the idea of teaching voice students to reach vocal resonances by training them to achieve a 1:6 ratio in the areas of two anatomical regions: the pharanx ...

Proteasome activator enhances survival of Huntington's disease neuronal model cells

... the UPS. From these results, we hypothesized that enhancing UPS function would improve catalytic degradation of abnormal proteins in HD. We first genetically engineered proteasome activators involved in either non-ubiquitinated protein degradation pathways (PA28ƒ×) or subunits of PA700, the 26S proteasome ubi...

Enhancing activity of marijuana-like chemicals in brain helps treat

... Malenka. The treatment used on the mice involves enhancing the activity of the chemicals where they occur naturally in the brain. "That is a really important difference, and it is why we think our manipulation of the chemicals is really different from smoking marijuana." The researchers began their stu...

Research finds music training 'tunes' human auditory system

...sorders. "Our study is the first to ask whether enhancing the sound environment -- in this case with musical training -- will positively affect the way an individual encodes sound even at a level as basic as the brainstem," says Patrick Wong, primary author of "Musical Experience Shapes Human Brainstem Enco...

Penn study on olfactory nerve cells shows why we smell better when we sniff

...e first is that it increases our ability to smell, enhancing the detection of odorous molecules in the air. The second is a peripheral drive in the brain to synchronize rhythmic activity, which is the concurrent firing of neurons in the olfactory bulb with breathing. "The mechanosensitivity may increase th...

Flavanols in cocoa may offer benefits to the brain

...y be beneficial in increasing brain blood flow and enhancing brain function among older adults or for others in situations where they may be cognitively impaired, such as fatigue or sleep deprivation.?/p> Norman K. Hollenberg, MD, PhD, of Harvard Medical School and Brigham and Women’s Hospital, presented ...

Scientists unlock mystery of embryonic stem cell signaling pathway

...ll-signaling pathway called the Wnt pathway, while enhancing the signal coming from the other arm of the Wnt pathway. The Wnt pathway is known to have dichotomous effects on stem cells i.e. both proliferative and differentiative. More specifically, IQ-1 blocks the coactivator p300 from interacting with the pro...

Boosting brain power -- with chocolate

Biologically inspired sensors can augment sonar, vision system in submarines

...elopment of an artificial lateral line is aimed at enhancing human ability to detect, navigate and survive in the underwater environment," said Liu, a Willett Scholar and a professor of electrical and computer engineering at Illinois. "Our goal is to develop an artificial device that mimics the functions and c...

Blocking immune cell action increases Alzheimer's-associated protein deposits

...oid-beta from the brain, our findings suggest that enhancing the accumulation of these cells may be beneficial to patients with early-stage Alzheimer's disease," says Andrew Luster, MD, PhD, director of the MGH Center for Immunology and Inflammatory Diseases and senior author of the report. The researcher...

New science of metagenomics 'will transform modern microbiology'

...luding making antibiotics, remediating oil spills, enhancing crop production, and producing biofuels. Historically, microbiology focused on the study of individual species of organisms that could be grown in a laboratory and examined under a microscope, but most of the life-supporting activities of microbes...

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

... coastal food webs," says Baum. "Solutions include enhancing protection of great sharks by substantially reducing fishing pressure on all of these species and enforcing bans on shark finning both in national waters and on the high seas." "Maintaining the populations of top predators is critical for sustain...

NASA satellite data helps assess the health of Florida's coral reef

... strategies that improve the health of reefs while enhancing the economies dependent on their success. Continued monitoring of coral reefs with the aid of sophisticated data from NASA satellites will help identify the causes of bleaching and ways to prevent it so that the impact of climate and man on these v...

Tiny Tampa Bay fish key to evolution of immune system

...lly correct, the study would offer the prospect of enhancing our understanding of the structural requirements for molecules used by the adaptive immune response to recognize and counter components of invading microbes. If so, it would provide an illustration of the potential for studies of diverse species, eve...

Sports cheats beware -- new test detects previously undetectable drug

Injecting performance enhancing corticosteroid hormones for other than medical treatment is banned, and tests exist that can detect injected hormones. Injecting synacthen, which stimulates the body to produce extra amounts of its own corticosteroid hormones is also banned. But unti...

Siberian lakes burp 'time-bomb' greenhouse gas

...grams of methane can be released to the atmosphere enhancing climate warming," Walter said. "This newly recognized source of methane is so far not included in climate models." Using remote sensing, aerial surveys and year-round, continuous measurements Walter and colleagues developed a new method of measuring...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

... is also at least one that stimulates osteoblasts, enhancing bone formation. A combined treatment will not only prevent the occurrence of osteoporosis, but also make the quality of bone even better. "Our discovery proves that inhibiting osteoclasts while simultaneously stimulating new bone formation can be...

Researchers examine why food tastes bad to chemotherapy recipients

...s proteins and enzymes, it may have some effect in enhancing the metallic flavor. They will also use in-vitro experiments in order to conduct experiments at higher concentrations without endangering anyone, Dietrich added. Perception of taste and odor is very complex, and like nutritional needs, varies depend...

Computer-based 'games' enhance mental function in patients with Alzheimer's

...ased tasks aimed at increasing mental activity and enhancing mental function can improve cognition in patients with Alzheimer's disease, serving as an effective addition to medications commonly used to treat the disease. Researchers found that the internet-accessible computer activities were even more successf...
