New study sheds light on cancer-protective properties of milk
ScienceDaily (Oct. 3, 2012) Milk consumption has been linked to improved health, with decreased risks of diabetes, metabolic syndrome, and colon cancer. A group of scientists in Sweden found that lactoferricin4-14 (Lfcin4-14), a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated
Sticky paper offers cheap, easy solution for paper-based diagnostics
ScienceDaily (Oct. 2, 2012) A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper — one of humanity’s oldest technologies — and build a device like a home-based pregnancy test that might work for malaria, diabetes or other diseases.
HIV ‘made’ new deadly Salmonella
30 September 2012 Last updated at 13:19 ET By James Gallagher Health and science reporter, BBC News An epidemic of a deadly strain of Salmonella has swept across the whole of Africa by “taking advantage” of the spread of HIV, according to an international team of researchers. Their study, published in Nature Genetics 1 , is the first to identify the separate cases as a single epidemic. One in four people in Africa infected with the strain died

Potentially dangerous new malaria mosquito identified
ScienceDaily (Sep. 28, 2012) University of Notre Dame entomologists are part of a team of researchers that recently discovered a potentially dangerous new malaria-transmitting mosquito. The as yet unnamed, and previously unreported, mosquito breeds in the western areas of Kenya and has an unknown DNA match to any of the existing malaria-transmitting species
Multiple similarities discovered between cancer cells and induced pluripotent stem cells
ScienceDaily (Sep. 28, 2012) UC Davis investigators have found new evidence that a promising type of stem cell now being considered for a variety of disease therapies is very similar to the type of cells that give rise to cancer. The findings suggest that although the cells — known as induced pluripotent stem cells (iPSCs) — show substantial promise as a source of replacement cells and tissues to treat injuries, disease and chronic conditions, scientists and physicians must move cautiously with any clinical use because iPSCs could also cause malignant cancer
Dynamics of DNA packaging helps regulate formation of heart
ScienceDaily (Sep. 27, 2012) A new regulator for heart formation has been discovered by studying how embryonic stem cells adjust the packaging of their DNA. This approach to finding genetic regulators, the scientists say, may have the power to provide insight into the development of any tissue in the body — liver, brain, blood and so on
Male DNA commonly found in women’s brains, likely from prior pregnancy with a male fetus
ScienceDaily (Sep. 26, 2012) Male DNA is commonly found in the brains of women, most likely derived from prior pregnancy with a male fetus, according to first-of-its-kind research conducted at Fred Hutchinson Cancer Research Center

Understanding how salamanders grow new limbs provides insights into potential of human regenerative medicine
ScienceDaily (Sep. 25, 2012) Based on two new studies by researchers at the Salk Institute for Biological Studies, regeneration of a new limb or organ in a human will be much more difficult than the mad scientist and supervillain, Dr. Curt Connors, made it seem in the Amazing Spider-man comics and films
