High consumption of red and processed meat over a long period of time is associated with an increased risk for a certain type of colon cancer, according to a study in the January 12 issue of JAMA.
Meat consumption has been associated with colorectal cancer in previous studies, but the strength of the association and types of meat involved have not been consistent, according to background information in the article. Few studies have evaluated long-term meat consumption or the relationship between meat consumption and the risk of rectal cancer. Clarifying the role of meat consumption and any subsequent development of colorectal cancer is important because meat is an integral component of diet in the United States and many other countries in which colorectal cancer is common. Per capita annual consumption of beef has increased in the United States since 1993, reversing a previous decrease since 1976.
Ann Chao, Ph.D., of the American Cancer Society, Atlanta, and colleagues examined the relationship between recent and long-term meat consumption and the risk of colon and rectal cancer. The study included 148,610 adults aged 50 to 74 years, residing in 21 states with population-based cancer registries, who provided information on meat consumption in 1982 and again in 1992/1993 when enrolled in the Cancer Prevention Study II (CPS II) Nutrition Cohort. Follow-up from time of enrollment in 1992/1993 through August 31, 2001, identified 1,667 incident colorectal cancers.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
