Poplar trees redirect resources in response to simulated attack

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have applied some of the same techniques used in medical imaging to track the distribution of nutrients in poplar trees in response to a simulated insect attack. The research provides new insights on a long-debated theory about how plants respond to environmental stress, and shows that radiotracer imaging can be a big he...

Measuring the impact of post-genomics on Mediterranean populations

A recent Genomed-Health 2005 workshop in Tunisia, supported by the European Commission, highlighted the role of the life sciences in improving health in countries bordering the Mediterranean Sea. Delegates at the event also discussed the importance of Euro-Mediterranean partnerships in order to capitalise on post-genomic research. The life sciences ?in particular following the mapping of t...

A new study examines how shared pathogens affect host populations

Many pathogens are able to infect multiple species within a community and are commonly transmitted across species. Cross-species transmission is often associated with pathogen emergence and therefore has been considered as a negative factor for humans, wildlife, and species of agricultural importance. Many pathogens like malaria, Lyme disease or West Nile encephalitis that infect multiple hosts a...

Are rice and wheat behind China's population boom?

The rapid growth of the earliest cities in northern China starting as far back as 2400 to 2000 BC is the result of successful rice farming combined with other crops, says University of Toronto anthropologist Gary Crawford. Although we often associate rice with Chinese agriculture, most archeologists have, until recently, thought it was exclusively millet that was the most important food as...

Ocean climate predicts elk population in Canadian Rockies

Mark Hebblewhite can look at specific climate statistics from the north Pacific Ocean and tell you how the elk are doing in Banff National Park. The University of Alberta doctoral student is the first researcher to show a correlation between the North Pacific Oscillation (NPO) and a mammal population. Based on many climate-related ocean measurements, researchers are able to determine posit...

Poor health care in Russia maybe causing Decline in its Population

Medical officials in Russia have reported to have said that more than two-thirds of births in Russia are marred by complications, and every second newborn discharged from a maternity clinic is suffering health problems. The number of normal births declined from 45.3 percent in 1992 to just 30 percent last year, said Olga Frolova, head of the statistics department of Russia's Academy o...

Alternative medicine more popular among HIV positive patients

Despite significant improvements in anti AIDS therapy, complimentary and alternative medicine seem to be more attractive to the AIDS positive patients, according to a new study. Among 191 HIV-positive outpatients surveyed about their use of complementary and alternative therapies, 67% said they had used alternative therapies at some point to control their HIV infection and 40% reported cu...

Alternative therapies popular with Parkinson's patients

Nearly half of people with Parkinson's disease are using one or more type of complementary and alternative medicine (CAM), such as vitamins, message or acupuncture. Researchers at Johns Hopkins University in the US have carried out a survey of more than 200 people with Parkinson's disease. Forty per cent use one or more forms of CAM - and 12 per cent use five or more different ones. There...
