Mosquito genes explain response to climate change
04-23-2007 · EurekAlert!University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate -- and are apparently evolving -- in animals in response to climate change. The map will allow researchers to narrow their focus to identify specific genes that control the seasonal development of animals.

- A molecular map for aging in mice
11-28-2007 · EurekAlert!
Researchers at the National Institute of Aging and Stanford University have used gene arrays to identify genes whose activity changes with age in 16 different mouse tissues. The study, published Nov. 30 in PLoS Genetics, uses a newly available database called AGEMAP to document the process of aging in mice at the molecular level. The work describes how aging affects different tissues in mice, and ultimately could help explain why lifespan is limited to just two years in mice.

- Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
01-23-2008 · EurekAlert!
Scientists have discovered of whole subsets of genes and proteins that govern how one species of diatom builds its shell. For oceanographers, the work might one day help them understand how thousands of different kinds of diatoms -- and their ability to remove carbon dioxide from the atmosphere -- might be affected by something like global climate change.

- Are current projections of climate change-impacts on biodiversity misleading?
11-21-2007 · EurekAlert!
A recent study, published in Ecography, has profound implications for the future study of diversity on Earth. The article challenges the current view that patterns of current climate are sufficient to explain and predict diversity, and proposes that historical climate patterns are also of strong importance to diversity prediction.

- Adaptation to global climate change is an essential response to a warming planet
02-07-2007 · EurekAlert!
Temperatures are rising on Earth, which is heating up the debate over global warming and the future of our planet, but what may be needed most to combat global warming is a greater focus on adapting to our changing planet, says a team of science policy experts writing in this week's Nature magazine.

- Global warring
07-09-2007 · EurekAlert!
Climate change, and the resulting shortage of ecological resources, could be to blame for armed conflicts in the future, according to David Zhang from the University of Hong Kong and colleagues. Their research, which highlights how temperature fluctuations and reduced agricultural production explain warfare frequency in eastern China in the past, has been published online in Springer's journal Human Ecology.

- Scientists identify gene that may indicate predisposition to schizophrenia
01-24-2007 · EurekAlert!
In a study from the January issue of the American Journal of Human Genetics, a research team lead by Xinzhi Zhao and Ruqi Tang (Shanghai Jiao Tong University) present evidence that genetic variation may indicate predisposition to schizophrenia. Specifically, their findings identify the chitinase 3-like 1 gene as a potential schizophrenia-susceptibility gene and suggest that the genes involved in biological response to adverse conditions are likely linked to schizophrenia.

- Climate experts search for answers in the oceans
12-11-2006 · European Space Agency (ESA)
By absorbing half of the carbon dioxide emitted into the atmosphere, the oceans have a profound influence on climate. However, their ability to take up this carbon dioxide might be impaired as a result of climate change. To determine their response to global warming, ESA has backed two projects that provide systematic data on key oceanic variables – colour and temperature.

- Gene variant increases risk for alcoholism following childhood abuse
06-26-2007 · EurekAlert!
Girls who suffered childhood sexual abuse are more likely to develop alcoholism later in life if they possess a particular variant of a gene involved in the body's response to stress, according to a new study led by researchers at the National Institute on Alcohol Abuse and Alcoholism, part of the National Institutes of Health. The new finding could help explain why some individuals are more resilient to profound childhood trauma than others.
