Big advance against cystic fibrosis: Stem cell researchers create lung surface tissue in a dish Posted: 05 Apr 2012 07:48 PM PDT Stem cell researchers have taken a critical step in making possible the discovery in the relatively near future of a drug to control cystic fibrosis, a fatal lung disease that claims about 500 lives each year, with 1,000 new cases diagnosed annually.

Scientists redraw the blueprint of the body's biological clock Posted: 05 Apr 2012 07:44 PM PDT The discovery of a major gear in the biological clock that tells the body when to sleep and metabolize food may lead to new drugs to treat sleep problems and metabolic disorders, including diabetes.

Detecting breast cancer's fingerprint in a droplet of blood Posted: 05 Apr 2012 10:16 AM PDT The earlier breast cancer is detected, the better the chance of successful treatment and long-term survival. However, early cancer diagnosis is still challenging as testing by mammography remains cumbersome, costly, and in many cases, cancer can only be detected at an advanced stage. Scientists have now developed a new microfluidics-based microarray that could one day radically change how and when cancer is diagnosed.

Breakthrough in IOP regulation in fight against glaucoma Posted: 05 Apr 2012 10:15 AM PDT Medical researchers have gained new insight regarding the regulation of intraocular pressure (IOP) in glaucoma -- an irreversible blinding disease that causes progressive visual impairment due to optic nerve damage and is the leading cause of blindness worldwide.

Baseball: Beanballs and the psychology of revenge Posted: 05 Apr 2012 10:15 AM PDT Baseball fans exhibit a high moral tolerance for a form of revenge not otherwise practiced in most of contemporary society: avenging a teammate who has been hit by a pitch by aiming a pitch at an opposing batter who was not previously involved. New research suggests that such systems of vicarious retribution, found throughout history, may not depend on an underlying assignment of moral responsibility.

Banned antibiotics found in poultry products Posted: 05 Apr 2012 10:14 AM PDT Researchers have found evidence suggesting that a class of antibiotics previously banned by the US government for poultry production is still in use.

Manipulating the immune system to develop 'next-gen' vaccines Posted: 05 Apr 2012 10:14 AM PDT The discovery of how a vital immune cell recognizes dead and damaged body cells could modernize vaccine technology by "tricking" cells into launching an immune response, leading to next-generation vaccines that are more specific, more effective and have fewer side-effects.

New stem cell line provides safe, prolific source for disease modeling and transplant studies Posted: 05 Apr 2012 10:14 AM PDT Researchers have generated a new type of human stem cell that can develop into numerous types of specialized cells, including functioning pancreatic beta cells that produce insulin. Called endodermal progenitor cells, the new cells show two important advantages over embryonic stem cells and induced pluripotent stem cells: they do not form tumors when transplanted into animals, and they can form functional pancreatic beta cells in the laboratory.

Heightened sensitivity to cheap, high-calorie food is linked with obesity Posted: 05 Apr 2012 10:14 AM PDT A major reason for the dramatic increase in obesity may be a heightened sensitivity to heavily advertised and easily accessible high-calorie foods.

Tackling dyslexia before kids learn to read Posted: 05 Apr 2012 10:14 AM PDT For children with dyslexia, the trouble begins even before they start reading and for reasons that don't necessarily reflect other language skills. This study for the first time reveals a causal connection between early problems with visual attention and a later diagnosis of dyslexia.

To prevent leukemia's dreaded return, go for the stem cells Posted: 05 Apr 2012 10:14 AM PDT Researchers have found a way to stop leukemia stem cells in their tracks. The advance in mice suggests that a combination approach to therapy might stamp out chronic myeloid leukemia for good.

Nature and nurture: World‐first discovery sheds new light on congenital birth defects Posted: 05 Apr 2012 10:12 AM PDT Scientists have made a landmark discovery that could help women minimize or even avoid the risk of having a baby born with congenital birth defects.

Disarming disease-causing bacteria Posted: 05 Apr 2012 06:29 AM PDT Scientists could produce new antibacterial treatments by disarming the molecular pumps bacteria use to bring disease-causing molecules in contact with animals and humans.

Handheld plasma flashlight rids skin of notorious pathogens Posted: 04 Apr 2012 06:00 PM PDT Scientists have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant.

Asthma: A vaccination that works using intramuscular injection Posted: 04 Apr 2012 07:29 AM PDT Asthma is a chronic inflammatory and respiratory disease caused by an abnormal reactivity to allergens in the environment. Of the several avenues of exploration that are currently being developed, vaccination appears to be the most promising approach. Scientists have now revealed an innovative vaccine against one of the allergens most frequently encountered in asthma patients.

Why some pain drugs become less effective over time Posted: 03 Apr 2012 02:19 PM PDT Researchers have identified how neural cells are able to build up resistance to opioid pain drugs within hours.
