Guest relationships can become collateral damage when hotel employees envy the relationships co-workers have with their bosses, according to an international team of researchers.

New York, USA - The number of people suffering from chronic hunger reached a record one billion globally in 2009, with Asia accounting for approximately two-thirds of the world's hungry.

In response, the Asia Society and the International Rice Research Institute (IRRI) have released an action plan to address food insecurity in Asia, with an emphasis on rice, the region's staple.

The Task Force's report, Never an Empty Bowl: Sustaining Food Security in Asia, outlines a strategy focused on three key areas:

Researchers from the University of Seville (US) have detected active pharmaceutical substances for the first time in the waters of the Doñana National Park and its surrounding areas. The results suggest eco-toxicological risks for aquatic organisms. The scientists recommend that advanced technologies should be used to treat urban waste water in order to remove these compounds.

Scientists are reporting significant changes in the distribution of coastal fish species in south-east Australia which they say are partly due to climate change.

In the smooth, white, bunny-suited clean-room world of silicon wafers and solar cells, it turns out that a little roughness may go a long way, perhaps all the way to making solar power an affordable energy source, say Stanford engineers.

Australian and American scientists have found a way of shrinking tumours in certain cancers – a finding that provides hope for new treatments.

The cancers in question are those caused by a new class of genes known as 'microRNAs', produced by parts of the genome that, until recently, were dismissed as 'junk DNA'. While much is still unknown about microRNAs, it is clear that they can interfere with how our genes are 'read'.

CHAMPAIGN, Ill. — Researchers report this month that MALAT1, a long non-coding RNA that is implicated in certain cancers, regulates pre-mRNA splicing – a critical step in the earliest stage of protein production. Their study appears in the journal Molecular Cell.

ROCHESTER, Minn. -- Mayo Clinic researchers and their international colleagues have discovered genetic variants that lead to severe arthritis for a subset of women when taking aromatase inhibitors to treat their breast cancer. This serious side effect is so painful that many women halt their lifesaving medication. The findings appear today in the online issue of Journal of Clinical Oncology.

DETROIT ¬¬– Genetic ancestry has no discernible influence on how African American patients with asthma respond to medication, according to a Henry Ford Hospital study.

Researchers found that improved lung function in patients after taking inhaled steroids was related to a series of baseline breathing function measures, not genetic ancestry. The study is published online at the Journal of Allergy & Clinical Immunology, http://www.aaaai.org/media/jaci/

STANFORD, Calif. - Add pine-bark extract to the list of dietary supplements that don't live up to their promises of improved health. A new study from the Stanford University School of Medicine shows that pine-bark extract had no effect in lowering blood pressure or reducing other risk factors for heart disease.

Senior author Randall Stafford, MD, PhD, said the findings are part of a growing body of evidence that antioxidant supplements don't improve heart function.

In about 40 percent of research participants undergoing medical imaging, radiologists may detect a tumor or infection unrelated to the study but that may be meaningful to the individual's health, according to a report in the September 27 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

An intensive lifestyle intervention appears to help individuals with type 2 diabetes lose weight and keep it off, along with improving fitness, control of blood glucose levels and risk factors for cardiovascular disease, according to a report in the September 27 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Home-based exercises followed by voluntary home training seem to be associated with long-term effects on balance and gait (manner of walking), and may help protect high-risk, elderly women from hip fractures, according to a report in the September 27 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Use of pine bark extract, at a dose of 200 milligrams per day, appears safe but did not improve risk factors for heart disease, according to a report in the September 27 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
