A new study published in BJS has demonstrated for the first time that a simple breath analysis could be used for colorectal cancer screening. The study is part of the "Improving Outcomes in Gastrointestinal Cancer" supplement.

Cancer tissue has different metabolism compared to normal healthy cells and produces some substances which can be detected in the breath of these patients. Analysis of the volatile organic compounds (VOCs) linked to cancer is a new frontier in cancer screening.

WASHINGTON (Dec. 5, 2012)-- The National Geographic Society today announced the next phase of its Genographic Project — the multiyear global research initiative that uses DNA to map the history of human migration. Building on seven years of global data collection, Genographic shines new light on humanity's collective past, yielding tantalizing clues about humankind's journey across the planet over the past 60,000 years.

Recently the Mediterranean diet has achieved lots of distinctions, from the inclusion by the UNESCO in the Olympus of the World heritage list to a long series of dedicated congresses and meetings held everywhere in the globe with the aim of promoting its healthy properties against the most threatening diseases such as cardiovascular disease and tumors. So the Mediterranean diet is an international star acclaimed by the scientific community as the best dietary paradigm.

New research shows that the concentration of sperm in men's semen has been in steady decline between 1989 and 2005 in France. In addition, there has been a decrease in the number of normally formed sperm. The study is published online today (Wednesday) in Europe's leading reproductive medicine journal Human Reproduction [1].

University of Leicester scientists will present groundbreaking new evidence about how a chemical found in red wine can help prevent cancer on Wednesday, December 5.

Experts from around the world are set to attend Resveratrol 2012, a major conference at the University which will assess the latest advances in the study of resveratrol – a compound found in the skins of red grapes.

The conference will feature new findings based on the last two years of research, which show how the chemical can help prevent cancer, heart disease and diabetes.

Researchers have discovered what may be the earliest dinosaur, a creature the size of a Labrador retriever, but with a five foot-long tail, that walked the Earth about 10 million years before more familiar dinosaurs like the small, swift-footed Eoraptor and Herrerasaurus.

The findings mean that the dinosaur lineage appeared 10 million to 15 million years earlier than fossils previously showed, originating in the Middle Triassic rather than in the Late Triassic period.

The study, by IIASA Evolution and Ecology Program postdoctoral fellow Tatsuya Sasaki, provides a simple new model that ties punishment by social exclusion to the benefits for the punisher. It may help explain how social exclusion arose in evolution, and how it promotes cooperation among groups.

Health inequalities between England's richest and poorest areas have widened in the ten years between 1999 and 2008. Researchers warn, in a study published today on bmj.com, that over the next ten years, we may experience smaller increases in life expectancy than in the past decade and health inequalities may rise at an even faster rate.

Colin P. West, M.D., Ph.D., and Denise M. Dupras, M.D., Ph.D., of Mayo Clinic, Rochester, Minn., conducted a study to evaluate career plans of internal medicine residents.

Kevin G. Volpp, M.D., Ph.D., of the Philadelphia Veterans Affairs Medical Center and University of Pennsylvania, Philadelphia, and colleagues conducted a study to determine whether a protected sleep period of 5 hours is feasible and effective in increasing the time slept by interns on extended duty overnight shifts.

Peter Yeates, M.B.B.S., M.Clin.Ed., of the University of Manchester, United Kingdom, and colleagues conducted a study to examine whether observations of the performance of postgraduate year 1 physicians influence raters' scores of subsequent performances.

Kevin W. Eva, Ph.D., of the University of British Columbia, Vancouver, and colleagues conducted a study to determine whether students deemed acceptable through a revised admissions protocol using a 12-station multiple mini-interview (MMI) would outperform rejected medical students when they later took the Canadian national licensing examinations after completing medical school. The MMI process requires candidates to rotate through brief sequential interviews with structured tasks and independent assessment within each interview.

Children with implanted heart-rhythm devices and their parents suffer from a lower quality of life compared with their healthy counterparts and may benefit from psychotherapy according to new research in Circulation: Arrhythmia & Electrophysiology, an American Heart Association journal.

Paolo Riva of the University of Milano-Bicocca and colleagues wanted to examine whether there might be a causal relationship between activity in the right ventrolateral prefrontal cortex (rVLPFC) – known to be involved in the regulation of physical pain and negative expressions of emotion – and experiences of social pain.
