Prostate Cancer :: Scientists design a PSA-activated protoxin that kills prostate cancer

Scientists have found a way of using a protein made by prostate cancer to target and kill the cancer cells themselves. In preliminary studies the new therapy affected only the prostate, without causing damage to other healthy tissues, and now it is being tested in a phase I clinical trial, according to research presented at the 18th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Prague on Friday.

Genome :: Decoded sea urchin genome shows surprising relationship to man

The Sea Urchin Genome Sequencing Project (SUGSP) Consortium, led by the Human Genome Sequencing Center at Baylor College of Medicine (BCM-HGSC) in Houston, announced today the decoding and analysis of the genome sequence of the sea urchin, Strongylocentrotus purpuratus.

Bladder Cancer :: Children’s exposure to smoking cigarettes linked to bladder cancer – UK

Children and adolescents may be even more susceptible to the harmful effects of tobacco smoke than adults – according to new research into bladder cancer published in next week?s edition of the International Journal of Cancer*.

Genome :: Decoded sea urchin genome shows surprising relationship to humans – Houston

HIV :: To slow AIDS in Russia, treat HIV-positive addicts – Stanford study

The key to combating AIDS in Russia may be to treat HIV-infected drug users. A new model estimating the spread of HIV in Russia suggests that treating injection drug users with antiretroviral medication will slow transmission of the virus among the general population.

Heart :: Seven-point system gauges seriousness of heart failure in elderly – Washington University

A simple points system may soon help guide treatment of elderly heart failure patients. Researchers at Washington University School of Medicine in St. Louis found that by counting how many of seven easy-to-obtain health factors a patient has, physicians can estimate the patient’s risk of dying.

Education :: Nonminority medical students more satisfied than minority students – Mayo study

Minorities account for 30 percent of the U.S. population, but only eight percent of the physician workforce, and experience less personal satisfaction during medical school than nonminority students, finds a Mayo Clinic study published in the November issue of Mayo Clinic Proceedings.

Ecology :: 1st international study group for new ‘movement’ discipline – Hebrew University

Movement ecology is on the move, with the world’s first international research group on this topic having begun its work this fall at the Hebrew University of Jerusalem’s Institute for Advanced Studies.

Life :: Scientists find new way to search for origin of life – DNA microarray technology

Over the last half century, researchers have found that mineral surfaces may have played critical roles organizing, or activating, molecules that would become essential ingredients to all life–such as amino acids (the building blocks of proteins) and nucleic acids (the essence of DNA). But which of the countless possible combinations of biomolecules and mineral surfaces were key to this evolution? This vexing question has stumped scientists for years because of the sheer volume of possibilities.

Biotechnology :: Nature’s process for nitrogen fixation caught in action – PNAS

A research team from Utah State University, Virginia Tech, and Northwestern University asked whether the biological process for nitrogen fixation, carried out by microbes that contain the enzyme nitrogenase, follows the same pathway as recently reported chemical methods. Their research method resulted in the ability to witness steps in the biological process that enables some microorganisms to convert atmospheric nitrogen to nutrients.
