New findings on astronaut vision loss
ScienceDaily (May 30, 2012) Could vision changes experienced by astronauts be linked to a vitamin B-12 or folate deficiency? While investigating the vision changes recently identified in astronauts, nutritional assessment data showed similarities to symptoms that occur with vitamin deficiencies, according to a new study published in the March edition of The Journal of Nutrition .

While investigating the vision changes recently identified in astronauts, nutritional assessment data showed similarities to symptoms that occur with vitamin deficiencies, according to a new study published in the March edition of The Journal of Nutrition . Approximately 20 percent of astronauts living on the International Space Station have reported post-flight vision changes.

Why swine flu virus is developing drug resistance
ScienceDaily (May 29, 2012) Computer chips of a type more commonly found in games consoles have been used by scientists at the University of Bristol to reveal how the flu virus resists anti-flu drugs such as Relenza and Tamiflu. Professor Adrian Mulholland and Dr Christopher Woods from Bristol’s School of Chemistry, together with colleagues in Thailand, used graphics processing units (GPUs) to simulate the molecular processes that take place when these drugs are used to treat the H1N1-2009 strain of influenza — commonly known as ‘swine flu’. Their results, published May 29 in Biochemistry , provide new insight that could lead to the development of the next generation of antiviral treatments for flu.
Earlier detection of bone loss may be in future: Isotope analysis rather than x-ray used for measurement
ScienceDaily (May 28, 2012) Are your bones getting stronger or weaker? Right now, it’s hard to know
Engineered microvessels provide a 3-D test bed for human diseases
ScienceDaily (May 28, 2012) Mice and monkeys don’t develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates
Like curry? New biological role identified for compound used in ancient medicine
ScienceDaily (May 25, 2012) Oregon State University scientists just identified a new reason why some curry dishes, made with spices humans have used for thousands of years, might be good for you. New research has discovered that curcumin, a compound found in the cooking spice turmeric, can cause a modest but measurable increase in levels of a protein that’s known to be important in the “innate” immune system, helping to prevent infection in humans and other animals.
Pivotal role for proteins: From helping turn carbs into energy to causing devastating disease
ScienceDaily (May 24, 2012) Research into how carbohydrates are converted into energy has led to a surprising discovery with implications for the treatment of a perplexing and potentially fatal neuromuscular disorder and possibly even cancer and heart disease. Until this study, the cause of this neuromuscular disorder was unknown
Pivotal role for proteins: From helping turn carbs into energy to causing devastating disease
ScienceDaily (May 24, 2012) Research into how carbohydrates are converted into energy has led to a surprising discovery with implications for the treatment of a perplexing and potentially fatal neuromuscular disorder and possibly even cancer and heart disease. Until this study, the cause of this neuromuscular disorder was unknown. But after obtaining DNA from three families with members who have the disorder, a team led by University of Utah scientists Jared Rutter, Ph.D., associate professor of biochemistry and Carl Thummel, Ph.D., professor of human genetics, sequenced two genes and identified two mutations that cause this devastating disease.
Activating genes that suppress tumors and inhibit cancer
ScienceDaily (May 21, 2012) A team of scientists has developed a promising new strategy for “reactivating” genes that cause cancer tumors to shrink and die.
