DARIEN, IL – A study in the April 1 issue of the journal SLEEP suggests that the risk of death is more than two times higher in older adults who have sleep apnea and report struggling with excessive daytime sleepiness.

PHILADELPHIA — Researchers have found that it may not be necessary to look for tumors directly in patients with prostate cancer — analyzing non-tumor tissue may be an effective option, according to study results published in Cancer Research, a journal of the American Association for Cancer Research.

Biological invasions get less prime-time coverage than natural disasters, but may be more economically damaging and warrant corresponding investments in preparedness and response planning, according to three biologists writing in the April issue of BioScience.

Eating a fatty fast food meal is never good for you, but washing that meal down with a coffee is even worse, according to a new University of Guelph study.

Researcher Marie-Soleil Beaudoin has discovered not only that a healthy person's blood sugar levels spike after eating a high-fat meal, but that the spike doubles after having both a fatty meal and caffeinated coffee – jumping to levels similar to those of people at risk for diabetes.

The new TNM 7 lung cancer staging system seems to be a better predictor of local or regional recurrence of lung cancer following surgery, according to a study published in the April issue of the Journal of Thoracic Oncology.

Being able to better define which patients might experience a cancer recurrence is important, especially given the controversies surrounding the use of adjuvant therapies, particularly postoperative radiation therapy (RT), for patients with non-small cell lung cancer (NSCLC).

A component in soybeans increases radiation's ability to kill lung cancer cells, according to a study published in the April issue of the Journal of Thoracic Oncology, the official monthly journal of the International Association for the Study of Lung Cancer.

Two species of gorillas live in central equatorial Africa. Divergence between the Western gorillas (Gorilla gorilla) and Eastern Gorillas (G. beringei) began between 0.9 and 1.6 million years ago and now the two species live several hundred kilometres apart. New research published by BioMed Central's open access journal BMC Evolutionary Biology shows that the divergence of Western lowland gorillas and the Critically Endangered Cross River gorillas (G. g. diehli) occurred more recently, about 17,800 years ago, during the Pleistocene era.

Research being presented today (01 April) at the UK National Stem Cell Network annual science conference provides another piece in the puzzle of why it can be so hard to produce large numbers of the same type of cell in the lab – a process that is vital for scaling up stem cell production for therapeutic use. This knowledge will help researchers to develop strategies for obtaining the desired cell type for use in either research or medicine.

Scientists have identified a new species of gigantic theropod dinosaur, a close relative of T. rex, from fossil skull and jaw bones discovered in China.

According to findings published online (01 April 2011) in the scientific journal Cretaceous Research, the newly named dinosaur species "Zhuchengtyrannus magnus" probably measured about 11 metres long, stood about 4 metres tall, and weighed close to 6 tonnes.

Screening does not significantly reduce prostate cancer deaths, but the risk of overdetection and overtreatment is considerable, concludes a 20-year study published on bmj.com today.

Prostate cancer is one of the most common cancers among men worldwide. Screening is widely used in many countries, but remains controversial because experts can't agree whether the benefits outweigh the potential harms and costs of overdiagnosis and overtreatment of healthy men.

BOSTON--A section of the AIDS virus's protein envelope once considered an improbable target for a vaccine now appears to be one of the most promising, new research by Dana-Farber Cancer Institute scientists indicates.

A specific genetic defect in one Chinese family shows that high blood pressure was inherited from the female parent, researchers report in Circulation Research: Journal of the American Heart Association.

Middle-aged adults with diabetes are much more likely to develop age-related conditions than their counterparts who don't have diabetes, according to a new study by the University of Michigan Health System and VA Ann Arbor Healthcare System.

Adults between 51 and 70 with diabetes developed age-related ailments like cognitive impairment, incontinence, falls, dizziness, vision impairment and pain at a faster rate than those without diabetes, the study found. Results were published in the March issue of the Journal of General Internal Medicine.

BOSTON—A report from the nation's leading cancer organizations shows rates of death in the United States from all cancers for men and women continued to decline between 2003 and 2007. The findings come from the latest Annual Report to the Nation on the Status of Cancer.

Hamilton, ON (March 31, 2011) - Good-bye itching, watering eyes and sneezing. McMaster University researchers have developed a vaccine which successfully treats people with an allergy to cats.

Traditionally, frequent allergy shots have been considered the most effective way to bring relief – other than getting rid of the family pet -- for the eight to 10% of the population allergic to cats.
