Progress in understanding the malarial parasite
About 2 million people die of malaria every year, of which more than a million are children in sub-Saharan Africa. Malaria is caused by a protozoan parasite belonging to the genus Plasmodium, and Plasmodium falciparum is responsible for the most severe form of malaria. view more (2007-09-14)
Can hearing voices in your head be a good thing?
Psychologists have launched a study to find out why some people who hear voices in their head consider it a positive experience while others find it distressing. view more (2006-09-14)
Genes involved in cell growth and cell division identified
A recent study shows that hundreds of genes contribute to cell growth and cell division. For the first time these genes, many of which are potential contributors to cancer, have been mapped in a single systematic study. view more (2006-02-23)
"Live fast, die young" applies to forests, too.
Forests provide humans with economically important and often irreplaceable products and services, and affect global climate by acting as sources and sinks of heat-trapping carbon dioxide. Yet the possible responses of forests to ongoing environmental changes are poorly understood. In the most recent issue of Ecology Letters, Stephenson and van... view more... (2005-04-19)
Limpets reveal possible fate of cold-blooded Antarctic animals
A limpet no bigger than a coin could reveal the possible fate of cold-blooded Antarctic marine animals according to new research published this week in The Journal of Experimental Biology. view more (2007-07-24)
Disease-impact models may rely on incorrect assumptions
Even when we know how a disease affects individual animals, it is challenging to predict what impact it will have on the whole population, and yet predicting how disease affects a population is a primary concern for wildlife conservation and even public health. view more (2006-04-13)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
Brain memory area modifies its wiring diagram during the female cycle
Researchers at Northwestern University and Columbia University have found that "wiring" in female rat brain memory area expands and retracts in relation to the amount of estrogen present during the estrous/menstrual cycle. view more (2005-11-15)
Ultrasounds show mothers' drinking shrinks fetal brain
Routine ultrasounds show that heavy drinkers who continue to imbibe after learning they are pregnant may carry fetuses with reduced skull and brain growth compared to those of abstainers or quitters, says a new study. view more (2006-04-28)
Tomorrow's endangered species: Act now to protect species not yet under threat
Conservationists should be acting now to protect mammals such as North American reindeer which risk extinction in the future as the human population grows, according to research published today. view more (2006-03-07)
The future of tropical forests
Deforestation and habitat loss are expected to lead to an extinction crisis among tropical forest species. Humans in rural settings contribute most to deforestation of extant tropical forests. view more (2006-04-07)
Protein holds back growth of head and neck tumors
A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels. view more (2006-02-01)
Eggs from embryonic stem cells could benefit sterile women
Monash researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs. view more (2005-06-20)
The effects of climate change on the physiology of alfalfa
The biologist Gorka Erice Soreasu, a researcher in the Department of Plant Biology of the University of Navarra, has studied the effects of climate change on the physiology of alfalfa. view more (2006-04-12)
Skin rash in patients treated for liver cancer determines survival
In a study of a new chemotherapy drug for liver cancer, researchers found that the development of a skin rash correlated directly with the patient's response to treatment. view more (2006-06-05)
America's national forests landlocked by sea of development
America's national forests are beginning to resemble "islands" of green wilderness, increasingly trapped by an expanding sea of new houses, a forestry researcher will report today at the 90th annual Ecological Society of America (ESA) meeting in Montreal, Canada. view more (2005-08-08)
Lack of vitamin D causes weight gain and stunts growth in girls
Insufficient vitamin D can stunt growth and foster weight gain during puberty, according to a new study published in the Journal of Clinical Endocrinology & Metabolism. view more (2008-12-11)
Scientists determine structure of enzyme that disrupts bacterial virulence
A team of biomedical researchers from Brandeis University and the University of Texas at Austin has determined the first 3-dimensional structure of an enzyme that may be pivotal in preventing certain bacterial infections in plants, animals and humans. view more (2005-08-31)
Big and fast growing infants at greater risk of later obesity
Large infants, and those who grow rapidly during the first two years of life, are at increased risk of obesity in childhood and adulthood, a study published online by the BMJ today (14 October 2005) has found. view more (2005-10-14)
Insect population growth likely accelerated by warmer climate
Insects have proven to be highly adaptable organisms, able through evolution to cope with a variety of environmental changes, including relatively recent changes in the world's climate. But like something out of a scary Halloween tale, new University of Washington research suggests insects' ability to adapt to warmer temperatures carries an... view more... (2006-10-31)
