Surprise finding: Pancreatic cancers progress to lethal stage slowly

Pancreatic cancer develops and spreads much more slowly than scientists have thought, according to new research from Johns Hopkins investigators. The finding indicates that there is a potentially broad window for diagnosis and prevention of the disease.

Forces for cancer spread: Genomic instability and evolutionary selection

In new research published today, researchers uncover evolution in action in cancer cells. They show the forces of evolution in pancreatic tumours mean that not only is cancer genetically different between different patients, but each new focus of cancer spread within a patient has acquired distinct mutations.

60 Utahns are among landmark large-scale genome sequencing study

(SALT LAKE CITY)—Just seven months after University of Utah geneticists took part in a landmark study that sequenced for the first time the genome of an entire Utah family, U of U researchers have taken part in another historic study that is the first large-scale genome sequencing project – 179 people representing three continents – and 60 Utahns played a major role in this study, too.

Revising the timeline for deadly pancreatic cancer

Pancreatic tumors are one of the most lethal cancers, with fewer than five percent of patients surviving five years after diagnosis. But a new study that peers deeply into the genetics of pancreatic cancer presents a bit of good news: an opportunity for early diagnosis. In contrast to earlier predictions, many pancreatic tumors are, in fact, slow growing, taking nearly 20 years to become lethal after the first genetic perturbations appear.

1000 Genomes Project publishes analysis of completed pilot phase

Small genetic differences between individuals help explain why some people have a higher risk than others for developing illnesses such as diabetes or cancer. Today in the journal Nature, the 1000 Genomes Project, an international public-private consortium, published the most comprehensive map of these genetic differences, called variations, estimated to contain approximately 95 percent of the genetic variation of any person on Earth.

Texas AM University becomes key player in global study to save Earth's endangered species

Texas A&M University is one of 10 international partners involved in the global conservation study and subsequent scientific paper, "The Impact of Conservation on the Status of the World's Vertebrates," that is scheduled to be published in Science, the academic journal of the American Association for the Advancement of Science.

Concerns about the safety of certain 'healthful' plant-based antioxidants

Scientists are calling for more research on the possibility that some supposedly healthful plant-based antioxidants — including those renowned for their apparent ability to prevent cancer — may actually aggravate or even cause cancer in some individuals. Their recommendation follows a study in which two such antioxidants — quercetin and ferulic acid — appeared to aggravate kidney cancer in severely diabetic laboratory rats. The study appears in ACS' bi-weekly Journal of Agricultural and Food Chemistry.

Cone of poison: The secret behind the cone snail's venom pump

Scientists have discovered the secret of how an amazing sea snail injects its venom after shooting a harpoon-like tooth into its prey — or some unlucky swimmer — at jetliner speeds. The creatures, called cone snails, use a highly specialized structure that instantly pumps the paralyzing venom through the tooth and into its target. Their study appears in ACS' monthly Journal of Proteome Research.

Tobacco and its evil cousin, nicotine? They're good -- as a pesticide!

Tobacco, used on a small scale as a natural organic pesticide for hundreds of years, is getting new scientific attention as a potential mass-produced alternative to traditional commercial pesticides. That's the topic of a report in ACS' bi-weekly journal Industrial & Engineering Chemistry Research.

Knowledge of genetic cancer risks often dies with patients, finds VCU Massey Cancer Center

Richmond, Va. (Oct. 27, 2010) – If you were dying from cancer, would you consider genetic testing? A recent study conducted by researchers from Virginia Commonwealth University Massey Cancer Center showed that most terminally ill cancer patients who were eligible for genetic testing never received it despite that it could potentially save a relative's life.

Glucosamine causes the death of pancreatic cells

Quebec City, October 27, 2010—High doses or prolonged use of glucosamine causes the death of pancreatic cells and could increase the risk of developing diabetes, according to a team of researchers at Université Laval's Faculty of Pharmacy. Details of this discovery were recently published on the website of the Journal of Endocrinology.

Large-scale fish farm production offsets environmental gains

VICTORIA – Industrial-scale aquaculture production magnifies environmental degradation, according to the first global assessment of the effects of marine finfish aquaculture (e.g. salmon, cod, turbot and grouper) released today. This is true even when farming operations implement the best current marine fish farming practices.

Dr. John Volpe and his team at the University of Victoria developed the Global Aquaculture Performance Index (GAPI), an unprecedented system for objectively measuring the environmental performance of fish farming.
