Chemist solves riddle of killer diseases (June 25, 2011) -- Using the tools of synthetic chemistry, a Copenhagen chemist has copied the endotoxin of bacteria causing diseases such as anthrax. This paves the way for new and efficient antibiotics. ... > full story

Interplay between cancer and aging in mice: Aging due to reduction in cell proliferation, not molecular damage, data suggest (June 25, 2011) -- Cancer risk increases with age, and scientists have long perceived a possible evolutionary tradeoff between longer lifespan and greater risk of cancer. Now, researchers have found direct evidence for that tradeoff in new data showing that expression of a key tumor suppressor protein induces premature aging in mice. ... > full story

Life expectancy for those with Type 1 diabetes improving (June 25, 2011) -- The life expectancy of people diagnosed with Type 1 diabetes between 1965 and 1980 dramatically increased, compared to people diagnosed with Type 1 diabetes between 1950 and 1964, according to a new study. ... > full story

Drug shows improved kidney function for type 2 diabetics (June 25, 2011) -- A new anti-inflammatory drug used by patients with type 2 diabetes improved their kidney function during a year-long study. ... > full story

Pollinators make critical contribution to healthy diets (June 25, 2011) -- Fruits and vegetables that provide the highest levels of vitamins and minerals to the human diet globally depend heavily on bees and other pollinating animals, according to a new study. ... > full story

Screen developed to identify new anticancer drug targets (June 25, 2011) -- Tumor suppressor genes normally control the growth of cells, but cancer can spring up when these genes are silenced by certain chemical reactions that modify chromosomes. Among the most common culprits responsible for inactivating these genes are histone deacetylases, a class of enzymes that remove acetyl groups from DNA-scaffolding proteins, and DNA methyltransferases, a family of enzymes that add methyl groups to DNA. ... > full story

Tracing cancer back to its source using computer dissection (June 25, 2011) -- A new computer-based system can distinguish between apparently similar secondary tumors and allow a cancer specialist to trace the metastases back to the site of the original cancer in the patient's body. ... > full story

Exposure to parental stress increases pollution-related lung damage in children (June 25, 2011) -- Psychosocial stress appears to enhance the lung-damaging effects of traffic-related pollution in children, according to new research. ... > full story

Artificial pancreas being developed to ease diabetes burden (June 25, 2011) -- Millions of people who have diabetes may soon be free of finger pricks and daily insulin dosing. Researchers are developing an artificial pancreas that will deliver insulin automatically and with an individualized precision never before possible. ... > full story

Common drugs linked to cognitive impairment and possibly to increased risk of death, study suggests (June 25, 2011) -- A large, long-term study confirms that medications with anticholinergic activity, which include many drugs frequently taken by older adults, cause cognitive impairment. The research is also the first to identify a possible link between these drugs -- which include over-the-counter and prescription sleep aids and incontinence treatments -- and risk of death. ... > full story

Astronomers reach for the stars to discover new cancer therapy (June 25, 2011) -- Research on celestial bodies may have an impact on the human body. Astronomers are working with medical physicists and radiation oncologists to develop a potential new radiation treatment -- one that is intended to be tougher on tumors, but gentler on healthy tissue. ... > full story

Some captive chimpanzees show signs of compromised mental health, research shows (June 24, 2011) -- A new study finds that serious behavioral abnormalities, some of which could be compared to mental illness in humans, are endemic among captive chimpanzees. While most behavior of zoo-living chimpanzees is 'normal' in that it is typical of their wild counterparts, abnormal behavior is endemic in this population despite enrichment efforts such as social housing, say researchers. ... > full story
