Individuals who drink more coffee (regular or decaffeinated) or tea appear to have a lower risk of developing type 2 diabetes, according to an analysis of previous studies reported in the December 14/28 issue of Archives of Internal Medicine.

Increased physical activity appears to be associated with a lower risk of cancer-specific and overall death in men with a history of colorectal cancer that has not spread to other parts of the body, according to a report in the December 14/28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Myopia (nearsightedness) may have been more common in Americans from 1999 to 2004 than it was 30 years ago, according to a report in the December issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Radiation doses from common CT procedures vary widely and are higher than generally thought, raising concerns about increased risk for cancer, according to a new study led by UCSF imaging specialists.
"In day-to-day clinical practice, we found significant variation in the radiation doses for the same type of computed tomography procedures within institutions and across institutions," said lead investigator Rebecca Smith-Bindman, MD, a professor of radiology at UCSF. "Our results highlight the need for greater standardization because this is a medical safety issue."
BOSTON ––– Men who have been treated for colorectal cancer can reduce their risk of dying from the disease by engaging in regular exercise, according to a new study by researchers at Dana-Farber Cancer Institute. The findings are published in the December 14 issue of the Archives of Internal Medicine.
A discovery by scientists at the University of East Anglia (UEA) could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity.
Published today by the leading scientific journal, Proceedings of the National Academy of Sciences (PNAS), the researchers have demonstrated for the first time the mechanism by which some bacteria survive by 'breathing rocks'.
A new microscopic system devised by researchers in MIT's department of materials science and engineering could provide a novel method for moving tiny objects inside a microchip, and could also provide new insights into how cells and other objects are propelled around within the body.
Genes that don't themselves directly affect the inherited characteristics of an organism but leave them increasingly open to variation may be a significant driving force of evolution, say two Johns Hopkins scientists.
Their proposed amended view of evolution is based on observations of genetic patterns outside of a cell's DNA and may better explain how organisms, including people, have adapted over hundreds of thousands of years to relatively rapidly changing environments.
A team of scientists from the UC San Diego School of Medicine and Osaka University in Japan have identified a protein switch that helps prevent liver damage, including inflammation, fibrosis and cancer. The findings suggest that a better understanding of how the protein, TAK1, works could lead to new insights into the development of liver disease and cancer.
This is shown by samples of ancient DNA, analysed by an international team of research scientists under the leadership of Professor Eske Willerslev from Copenhagen University. Analyses of ancient DNA thereby once again revoke results of more common methods of dating, such as carbon 14 analysis of bone and tooth remains from extinct animals. These methods which had previously dated the extinction of mammoths and prehistoric horses in Central Asia to within 13-15,000 years ago.
MAYWOOD, Il. -- A new study could point the way to the development of better drugs to fight a deadly form of childhood leukemia called mixed-lineage leukemia (MLL).
The study will help researchers in their search for what could be the first highly effective drug for MLL. Such a drug would work by disabling a protein that turns normal blood cells into cancer cells.
Researchers from Loyola University Chicago Stritch School of Medicine and the University of Virginia reported results online Dec. 13 in the journal Nature Structural & Molecular Biology.
WEST LAFAYETTE, Ind. - Tiny nanoprobes have shown to be effective in delivering cancer drugs more directly to tumor cells - mitigating the damage to nearby healthy cells - and Purdue University research has shown that the nanoprobes are getting the drugs to right cellular compartments.
It may seem odd to add scent to products like sewing thread, automobile tires, and tennis balls, as some companies have done. But a new study in the Journal of Consumer Research says scent helps consumers remember product information.
"Product scent may be particularly effective at enhancing memory for product information as a function of its ability to enhance a product's distinctiveness within its surrounding context," write authors Aradhna Krishna (University of Michigan), May Lwin (Nanyang Technological University, Singapore), and Maureen Morrin (Rutgers University).
Imagine a huge spool of film containing thousands of sequences of random scenes. Without a talented editor, a screening would have no meaning.
The RNA "spools" that make up DNA in our genes need careful editing, too. Genes are composed of meaningful sequences, called exons, separated by meaningless junk sections called introns. In order for cells to produce RNA — the material that is required to create proteins that are vital for life — they must precisely remove meaningless introns and bind meaningful exons together, a process called "splicing".
Planning—regarding money or time—can bring tangible benefits to consumers. A new study in the Journal of Consumer Research discovered what makes planners tick.
