| Potential Key To Curing Tuberculosis
October 4, 2009 at 5:00 pm
|
| Researchers have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. They have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis -- a contagious disease that kills 1.5 to 2 million people worldwide annually. |
| Sierra Nevada Birds Move In Response To Warmer, Wetter Climate
October 4, 2009 at 5:00 pm
|
| If the climate is not quite right, birds will up and move rather than stick around and sweat it out, according to a new study. The findings reveal that most of the bird species studied in California's Sierra Nevada mountains have adjusted to climate change over the last century by moving to sites with the temperature and precipitation conditions they favored. |

| New Approach To Targeting The Hidden Reservoir Of HIV
October 4, 2009 at 11:00 am
|
| The drugs used to treat individuals infected with HIV-1 keep the virus under control but do not eliminate it from the body, some remains hidden in immune cells known as resting CD4+ T cells. However, researchers have now developed an in vitro system that faithfully mimics the situation in people and used it to identify a compound that can get at this hidden HIV-1 and eliminate it from the cells. |
| Inventors Offer Ecofriendly Substitutes For Polystyrene
October 4, 2009 at 11:00 am
|
| Rigid, custom-fit foam pieces like those that keep computer monitors firmly in place inside cardboard boxes during shipping could be made with eco-friendly starch from potatoes, wheat or corn, instead of from petroleum, according to a research plant physiologist. Opting for starch in place of petroleum-derived polystyrene would lessen America's dependence on petroleum. |

| Chemistry Of Titan's Hazy Atmosphere Unraveled
October 4, 2009 at 11:00 am
|
| A team of University of Hawai'i at Manoa researchers led by Ralf Kaiser, physical chemist at UH Manoa, unraveled the chemical evolution of the orange-brownish colored atmosphere of Saturn's moon Titan, the only solar system body besides Venus and Earth with a solid surface and thick atmosphere. |
| Difficulties With Daily Activities Associated With Progression To Dementia
October 4, 2009 at 11:00 am
|
| Among individuals with mild cognitive impairment, often considered a transitional state between normal cognitive function and Alzheimer's dementia, those who have more difficulties performing routine activities appear more likely to progress quickly to dementia, according to a new report. |
| Fish-Killing Toxin Could Kill Cancer Cells
October 4, 2009 at 5:00 am
|
| A powerful fish-killing toxin could have cancer-killing properties as well. The toxin, called euglenophycin, has a molecular structure similar to that of solenopsin, an alkaloid from fire ant venom known to inhibit tumor development. |
| Heart Of A Galaxy Emits Gamma Rays
October 4, 2009 at 5:00 am
|
| The H.E.S.S. telescope system detects high-energy rays from the starburst region of a galactic system outside the Milky Way. |
| Chronic Pain Treatments Work Better Together, Says Anesthesiologist
October 4, 2009 at 5:00 am
|
| People who suffer from debilitating neuropathic pain may get more relief and sleep better by combining two commonly-prescribed drugs. |
| Researchers Determine Composition Of Centromeric Chromatin
October 4, 2009 at 5:00 am
|
| Researchers have provided new evidence to clarify the structure of nucleosomes containing Cse4, a centromere-specific histone protein required for proper kinetochore function, which plays a critical role in the process of mitosis. |
| Medical Ethics Experts Identify, Address Key Issues In H1N1 Pandemic
October 4, 2009 at 5:00 am
|
| The anticipated onset of a second wave of the H1N1 influenza pandemic could present a host of thorny medical ethics issues best considered well in advance, according bioethicists. |
| Gene Controlling Number Of Brain Cells Pinpointed
October 4, 2009 at 12:00 am
|
| A new study suggests that a single gene, called GSK-3, controls the signals that determine how many neurons actually end up composing the brain. This has important implications for patients with neuropsychiatric illness, as links have recently been drawn between GSK-3 and schizophrenia, depression and bipolar disorder. |
| Global Death Toll: One Million Premature Babies Every Year
October 4, 2009 at 12:00 am
|
| Some 13 million babies worldwide were born preterm and more than one million die annually as a result, according to the the March of Dimes. The highest preterm birth rates are in Africa, followed by North America (United States and Canada). |
| Graphite Mimics Iron's Magnetism
October 4, 2009 at 12:00 am
|
| Researchers show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material. |
| New Type Of Genetic Change Identified In Inherited Cancer
October 4, 2009 at 12:00 am

| Designing Drugs And Their Antidotes Together Improves Patient Care
October 4, 2009 at 12:00 am
|
| Imagine a surgical patient on a blood-thinning drug who starts bleeding more than expected, and an antidote that works immediately -- because the blood thinner and antidote were designed to work together. Researchers have engineered a way to do this for an entire, versatile class of drugs called aptamers. |
| A Better Way To Watch Bacteria Swim

|
| Researchers have developed a new method for studying bacterial swimming, one that allows them to trap Escherichia coli bacteria and modify the microbes' environment without hindering the way they move. The new approach uses optical traps, microfluidic chambers and fluorescence to get an improved picture of how E. coli get around. |
| Study Finds 231 New Genes Associated With Head And Neck Cancer
October 4, 2009 at 12:00 am

| Understanding A Cell's Split Personality Aids Synthetic Circuits
October 4, 2009 at 12:00 am
|
| As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way. |
| Hypertension And Diabetes Are Concern In Long-Term Care Of Liver Transplant Patients
October 4, 2009 at 12:00 am
|
| A recent study looked at post-transplant care to determine whether primary care physicians (PCPs) or hepatologists are better suited to manage the overall health care of patients who received a liver transplant (LT). Researchers learned that hepatologists believe metabolic complications to be common in LT patients, but not well controlled. The hepatologists surveyed also felt that PCPs should be responsible for managing these conditions, but that this group was not taking an active role. | |
