Scientists have developed nanometer-sized "nanoworms" that can cruise through the bloodstream without significant interference from the body's immune defense system and--like tiny anti-cancer missiles--home in on tumors. Source: ScienceDaily: Latest Science News | 7 May 2008 | 6:00 pm
Scientists have invented a unique robotic device to assist with the physical rehabilitation process of patients suffering from neurological damages to their upper extremities such as those due to stroke or Parkinson's disease. They designed and built the device to aid physical therapists and their patients to retrain injured muscles. Source: ScienceDaily: Latest Science News | 7 May 2008 | 6:00 pm
It has long been known that type 2 diabetes is linked to obesity, particularly fat inside the belly. Now, researchers have found that fat from other areas of the body can actually reduce insulin resistance and improve insulin sensitivity. Researchers have found that subcutaneous fat can reduce insulin resistance and improve insulin sensitivity. Source: ScienceDaily: Latest Science News | 7 May 2008 | 6:00 pm
Researchers have discovered how a mole develops into melanoma by showing the interaction of two key proteins involved in 60-70 percent of tumors. The scientists also demonstrate that therapeutic targeting of these proteins is necessary for drugs to effectively treat this deadly form of cancer.

Whether a young man's mother earned a college degree and whether she worked outside the home while he was growing up seems to have an effect years later when he considers his ideal wife, according to a new study. High-achieving men -- those who earn salaries in the top 10 percent for their age and/or have a graduate degree -- are highly likely to marry a woman whose education level mirrors their mom's.

Researchers in Korea report development of a way to double production of a sticky protein from marine mussels destined for use as an antibacterial coating to prevent life-threatening infections in medical implants. The coating, produced by genetically-engineered bacteria, could cut medical costs and improve implant safety, the researchers say. Source: ScienceDaily: Latest Science News | 7 May 2008 | 3:00 pm
A gut hormone that causes people to eat more does so by making food appear more desirable, suggests a new report in Cell Metabolism. In a brain imaging study of individuals, the researchers found that reward centers respond more strongly to pictures of food in subjects who had received an infusion of the hormone known as ghrelin. The findings suggest that the two drives for feeding --metabolic signals and pleasure signals -- are actually intertwined. Source: ScienceDaily: Latest Science News | 7 May 2008 | 3:00 pm
Gambling activity is widespread among US adolescents and young adults ages 14 through 21, according to a new study. Results of the first national survey of its kind show problem gambling -- described as gambling with three or more negative consequences (for example, gambling more than you intended or stealing money to gamble) in the past year -- occurring at a rate of 2.1 percent among youth 14 to 21. That percentage projects to approximately 750,000 young problem gamblers nationwide. Source: ScienceDaily: Latest Science News | 7 May 2008 | 3:00 pm
Researchers have shown for the first time that thrombopoietin, a naturally occurring protein being developed as a pharmaceutical to increase platelet count in cancer patients during chemotherapy, can also protect the heart against injury during a heart attack. Currently there are no therapies available to directly protect the heart against the damaging effects of a heart attack. The study was published in Cardiovascular Research.
