Spotting a trend in the genes: Three genes that cause cancer and disease in humans also 'paint' spots on butts of fruit flies Posted: 12 Oct 2012 11:37 AM PDT Spots on the butts of fruit flies are really, really small. But what a researcher and his graduate student are discovering about them could be gigantic. Researchers have discovered that three genes that cause cancer and disease in humans also "paint" the spots on the fly's body. This discovery could enable researchers to study how those genes work in fruit flies and apply that knowledge to treating cancer in people.

NASA's Ironman-like exoskeleton could give astronauts, paraplegics improved mobility and strength Posted: 12 Oct 2012 11:19 AM PDT Marvel Comic's fictional superhero, Ironman, uses a powered armor suit that allows him superhuman strength. While NASA's X1 robotic exoskeleton can't do what you see in the movies, the latest robotic, space technology, spinoff derived from NASA's Robonaut 2 project may someday help astronauts stay healthier in space with the added benefit of assisting paraplegics in walking here on Earth.

Blood cells may offer telltale clues in cancer diagnosis Posted: 12 Oct 2012 11:18 AM PDT Researchers are probing the potential use of blood cell variation as a diagnostic, predictive, and research tool in cancer biology.

Molecular basis of infection of tick-transmitted disease uncovered Posted: 12 Oct 2012 11:15 AM PDT Researchers have identified the "keys" and "doors" of a bacterium responsible for a series of tick-transmitted diseases. These findings may point researchers toward the development of a single vaccine that protects against members of an entire family of bacteria that cause disease in humans, domestic animals and livestock.

Neural-like stem cells from muscle tissue may hold key to cell therapies for neurodegenerative diseases Posted: 12 Oct 2012 09:21 AM PDT Scientists have taken the first steps to create neural-like stem cells from muscle tissue in animals.

The worst noises in the world: Why we recoil at unpleasant sounds Posted: 12 Oct 2012 08:24 AM PDT Heightened activity between the emotional and auditory parts of the brain explains why the sound of chalk on a blackboard or a knife on a bottle is so unpleasant.

Body's own recycling system: Researchers discover 'molecular emergency brake' in charge of regulating self-digestion Posted: 12 Oct 2012 08:24 AM PDT Times of distress literally eat away at the core of starving cells: They start to digest their own parts and recycle them for metabolic purposes. Researchers have discovered that a "molecular brake" is in charge of regulating autophagy to keep it from getting out of control.

Cells control energy metabolism via hedgehog signalling pathway Posted: 12 Oct 2012 08:21 AM PDT Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists have resolved a new molecular circuit controlling cellular metabolism. The previously unknown signalling pathway, acting downstream of the hedgehog protein enables muscle cells and brown fat cells to absorb sugars without relying on insulin. Substances that selectively activate the signalling pathway could thus be utilized in the treatment of diabetes and obesity. With their results, the researchers are also able to explain why various new anti-cancer agents have induced mysterious pronounced side effects in the clinics.

Prostate cancer: Curcumin curbs metastases, study shows Posted: 12 Oct 2012 08:21 AM PDT Powdered turmeric has been used for centuries to treat osteoarthritis and other illnesses. Its active ingredient, curcumin, inhibits inflammatory reactions. A new study now shows that it can also inhibit formation of metastases.

New gene test flags risk of serious complications in sarcoidosis Posted: 12 Oct 2012 07:26 AM PDT Researchers have identified a genetic signature that distinguishes patients with complicated sarcoidosis, an inflammatory lung disease that can be fatal, from patients with a more benign form of the disease.

Tying our fate to molecular markings Posted: 12 Oct 2012 07:26 AM PDT A physicist has helped discover that understanding how a chemical mark on our DNA affects gene expression could be as useful to scientists as fingerprints are to police at a crime scene. In a new study, researchers show that variable methylation is predictive of age, gender, stress, cancer and early-life socioeconomic status within a population.

Transplantation of embryonic neurons raises hope for treating brain diseases Posted: 12 Oct 2012 07:21 AM PDT The unexpected survival of embryonic neurons transplanted into the brains of newborn mice in a series of experiments raises hope for the possibility of using neuronal transplantation to treat diseases like Alzheimer's, epilepsy, Huntington's, Parkinson's and schizophrenia.

Shape matters in DNA nanoparticle therapy: Particles could become a safer, more effective delivery vehicle for gene therapy Posted: 12 Oct 2012 04:48 AM PDT Researchers have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases. This study is also noteworthy because this gene therapy technique does not use a virus to carry DNA into cells.

Old adage 'sleep on it' is true -- but only if it's a really difficult problem, study shows Posted: 12 Oct 2012 04:47 AM PDT A new study has found that sleeping on a problem really can help people to find a solution. The study tested whether sleep or time spent awake worked best in helping people find the solutions to a range of problem solving tasks.

Reason discovered for the toxicity of indoor mould Posted: 12 Oct 2012 04:46 AM PDT A team of researchers from Finland has discovered how indoor mold makes people sick. The only remedy is to heal the living environment, they say.

Exposure to traffic air pollution in infancy impairs lung function in children Posted: 12 Oct 2012 04:43 AM PDT Exposure to ambient air pollution from traffic during infancy is associated with lung function deficits in children up to eight years of age, particularly among children sensitized to common allergens, according to a new study.

Expectant parents have different stress reactions to relationship conflict Posted: 11 Oct 2012 04:52 PM PDT A new study on the physiological effects of stress has found that expectant parents respond differently to arguments depending on the presence of ongoing individual or relationship difficulties such as anxiety or chronic relationship conflict.
