- First-ever study to link increased mortality specifically to carbon dioxide emissions
01-03-2008 · EurekAlert!
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

- Environmental epigenetics has potential for preventing and treating disease
01-31-2008 · EurekAlert!
New research on environmental influences on health and disease has begun to shed light on why genetically identical individuals demonstrate different characteristics, such as susceptibility to disease. Scientists have found that environmental exposure to nutritional, chemical and physical factors can alter the epigenome. Literally meaning "above the genome," the epigenome refers to differences in gene expression that are inherited without changing the sequence of DNA.

- UC Davis scientists' groundbreaking research: Mate-attracting chemicals
10-27-2006 · EurekAlert!
It's all about "the birds and the bees." And now, "the silkworm moths and the fruit flies."A chemical ecologist and a genetics researcher at the University of California, Davis, have joined forces to trick fruit flies into thinking that silkworm moths are potential mates.Groundbreaking research in the labs of chemical ecologist Walter Leal and genetics researcher Deborah Kimbrell shows that genetically engineered fruit flies responded to the silkworm moth scent of a female.

- Compact, wavelength-on-demand Quantum Cascade Laser chip offers ultra-sensitive chemical sensing
12-03-2007 · EurekAlert!
Engineers from Harvard University have demonstrated a highly versatile, compact and portable Quantum Cascade Laser sensor for the fast detection of a large number of chemicals, ranging from infinitesimal traces of gases to liquids, by broad tuning of the emission wavelength. The potential range of applications is huge, including homeland security, medical diagnostics such as breadth analysis, pollution monitoring, and environmental sensing of the greenhouse gases responsible for global warming.

- Relative abundance of common microbes living in the gut may contribute to obesity
12-20-2006 · EurekAlert!
A link between obesity and the microbial communities living in our guts is suggested by new research at Washington University School of Medicine in St. Louis. The findings indicate that our gut microbes are biomarkers, mediators and potential therapeutic targets in the war against the worldwide obesity epidemic.

- Researchers genetically engineer micro-organisms into tiny factories
09-18-2007 · EurekAlert!
Micro-organisms may soon be efficiently and inexpensively producing novel pharmaceutical compounds, such as flavonoids, that fight aging, cancer or obesity, as well as high-value chemicals, as the result of research being conducted by University at Buffalo researchers.

- Chewing gum may help reduce cravings and control appetite
10-22-2007 · EurekAlert!
A research study to be presented at the 2007 Annual Scientific Meeting of The Obesity Society, found that chewing gum before an afternoon snack helped reduce hunger, diminish cravings and promote fullness among individuals who limit their overall calorie intake. Calorie intake from snacks was significantly reduced by 25 calories. Overall, this study demonstrates clearly the benefits of chewing gum and highlights the potential role of chewing gum in appetite control and weight management.

- Parasitic Plants Sniff Out Hosts
09-30-2006 · ScienceDaily
Parasitic plants do not haphazardly flail about looking for a host but sense volatile chemicals produced by other plants and identify potential hosts by their emissions, according to a team of Penn State chemical ecologists.

- Toxic releases down from North American industry leaders, increasing from other facilities
10-18-2007 · EurekAlert!
The latest Taking Stock report from the Commission for Environmental Cooperation reveals a continued decline in releases of toxic chemicals to the environment -- 15 percent for the US and Canada from 1998 to 2004 -- driven by a group of industrial facilities that are the largest generators of emissions.The report also, however, reveals a substantial increase in chemical releases and transfers by a much larger group of industrial facilities that report lower emission volumes.

- A unique twin study on the increased cardiometabolic risk in obesity
02-13-2007 · EurekAlert!
A unique monozygotic twin study by Finnish researchers found that obesity, already in its early stages and independent of genetic influences, is associated with deleterious alterations in the lipid metabolism known to facilitate atherogenesis, inflammation and insulin resistance. By studying monozygotic twins discordant for obesity the research group was able to eliminate effects caused by genetic differences related to obesity and reveal effects attributable to environmental and life-style differences.
