Brown University researchers may have discovered what’s responsible for discrepant findings between dozens of fundamental studies of the biology of aging. A drug commonly used in research with C. elegans worms, they report, has had unanticipated effects on lifespan. (more…)
A team of researchers from have discovered that lycopene – the red pigment in tomatoes – is extremely successful at guarding against the harmful effects of radiation.
Dr Ruth Edge from The University of Manchester, together with her colleagues Professor George Truscott from Keele University and Professors Fritz Boehm & Christian Witt from Berlin, undertook a study of lycopene (one of the carotenoids – plant pigments found in many fruits and vegetables) and its effectiveness at protecting against radiation at the University of Manchester’s Dalton Cumbrian Facility, part of the Dalton Nuclear Institute.
Henry VIII may have suffered repeated traumatic brain injuries similar to those experienced by football players and others who receive repeated blows to the head, according to research by a Yale University expert in cognitive neurology. (more…)
Earlier this month, the U.S. Preventive Services Task Force released new recommendations on screening for breast cancer, which differed slightly from new recommendations by the American Cancer Society published in October and also from recommendations by the American College of Obstetricians and Gynecologists last updated in 2011.

AUSTIN, Texas — Researchers at The University of Texas at Austin have discovered that a type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous. The finding, published in the Proceedings of the National Academy of Sciences, contributes to a growing body of research that implicates the environment around a cancer in its spread — an area of study that holds promise for new alternatives to treat the disease.

Approach borrows from technique of inhibiting protein fibers that cause Alzheimer’s and Parkinson’s diseases
UCLA scientists have developed a promising novel method to treat gynecologic tumors. The approach focuses on a protein called p53, which is commonly mutated in women who have high-grade serous ovarian cancer, the deadliest form of reproductive cancer. In many women with the disease, the cancer is very advanced by the time it is diagnosed and is therefore difficult to treat. (more…)
Senckenberg-Wissenschaftler haben erstmalig Borrelien in deutschen Stechmücken nachgewiesen. Die drei identifizierten Arten der Bakterien können beim Menschen die Multisystemerkrankung Lyme-Borreliose auslösen. In ihrer kürzlich im Fachjournal „Ticks and Tick-borne Diseases“ veröffentlichten Studie zeigen die Forschenden außerdem, dass die Krankheitserreger die Umwandlung der Mückenlarve zur Puppe und schließlich zum erwachsenen Tier überleben. Auch wenn die Mücken potentielle Borreliose-Vektoren sein können, spielen sie nach derzeitigem Erkenntnisstand höchstens eine untergeordnete Rolle bei der Übertragung der Krankheitserreger. (more…)
