Nanoscale DNA sequencing could spur revolution in personal health care (August 21, 2010) -- In experiments with potentially broad health care implications, researchers have devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively. That could open the door for more effective individualized medicine, for example providing blueprints of genetic predispositions for specific conditions and diseases such as cancer, diabetes or addiction. ... > full story
Virus may act as 'evolution-proof' biopesticide against malaria (August 21, 2010) -- A naturally occurring virus in mosquitoes may serve as a "late-life-acting" insecticide by killing older adult mosquitoes that are responsible for the bulk of malaria transmission. ... > full story
Newly identified RNA sequence is key in microRNA processing (August 21, 2010) -- Researchers have uncovered a mechanism that regulates the processing of microRNAs (miRNAs), molecules that regulate cell growth, development, and stress response. The discovery helps researchers understand the links between miRNA expression and chronic disease. ... > full story
Today's superheroes send wrong image to boys, say researchers (August 21, 2010) -- Watching superheroes beat up villains may not be the best image for boys to see if society wants to promote kinder, less stereotypical male behaviors, according to psychologists. ... > full story
Researchers identify two FDA approved drugs that may fight HIV (August 21, 2010) -- Researchers have identified two drugs that, when combined, may serve as an effective treatment for HIV. The two drugs, decitabine and gemcitabine -- both FDA approved and currently used in pre-cancer and cancer therapy -- were found to eliminate HIV infection in the mouse model by causing the virus to mutate itself to death -- an outcome researchers dubbed "lethal mutagenesis." ... > full story
New targets for anti-angiogenesis drugs revealed (August 21, 2010) -- A new study describes a novel pathway of angiogenesis, the growth of new blood vessels. Targeting the new pathway, scientists identified two approaches that significantly reduced angiogenesis in mice. These discoveries may lead to novel treatments for diseases caused by excessive angiogenesis, including corneal graft rejection, age-related macular degeneration, cancer and diabetes. ... > full story
Disturbances in certain genes play a role in autism (August 21, 2010) -- Autism researchers have found that autism can be partially explained by abnormalities in certain genes. The group's results could, in the long run, pave the way for more appropriate treatments for autism. ... > full story
Drug addicts get hooked via prescriptions, keep using 'to feel like a better person,' research shows (August 21, 2010) -- If you want to know how people become addicted and why they keep using drugs, ask the people who are addicted. Thirty-one of 75 patients hospitalized for opioid detoxification told physicians they first got hooked on drugs legitimately prescribed for pain. ... > full story
Autism linked to multisensory integration (August 20, 2010) -- A new study has provided concrete evidence that children with autism spectrum disorders process sensory information such as sound, touch and vision differently than typically developing children. ... > full story
Frozen flies may yield secrets for human organ transplants (August 20, 2010) -- Frozen fruit fly cells may hold key to human organ transplant process, according to new research. ... > full story
Smart fungus disarms plant, animal and human immunity (August 20, 2010) -- Fungal and bacterial pathogens are well capable of infecting plants, animals and humans despite their immune systems. Fungi penetrate leafs, stalks and roots, or skin, intestines and lungs, to infect their hosts. Researchers have now discovered how this is possible. They found that the fungus secretes a protein that makes stray building blocks of the fungal cell wall invisible for the immune system of the plant. In this way infection remains unnoticed. ... > full story
Innovative imaging system may boost speed and accuracy in treatment of heart rhythm disorder (August 20, 2010) -- Researchers have developed a novel 3-D imaging approach that may improve the accuracy of treatment for ventricular tachycardia, a potentially life-threatening heart rhythm disorder that causes the heart to beat too fast. The new approach couples CT (computed tomography) images with conventional ablation techniques to eliminate erratic electrical circuits in the heart that produce arrhythmias. ... > full story
