which processes the city's rich chemical landscapes oe and it is no longer possible to tell which of these vibrant structures are artificial, or natural.

and the lavish use of chemicals, the machinery sowing this new revolution includes supercomputers, molecular biology and arrays of sensors.

and the chemicals used in fire extinguishers can be toxic (halons, the most effective chemical fire suppressant, create holes in the ozone layer.

So the Defense Advanced Research Projects Agency at the Pentagon has developed a hand-held wand that snuffs out fires, without chemicals.

According to the program s manager, Dr. Matt Goodman, an electric field destabilizes the flame s underlying structure rather than blanketing the fire to smother it.

farming in the US heartland can be pushed toward a model based on biodiversity over monocropping, farmer skill in place of brute chemicals,

Revenue from industrial chemicals made through synthetic biology is already as high as $1. 5 billion,

#oewe no longer can afford to continue to pollute our skies with heat, chemicals and noise,

and slow lumbering slurry bombers that each dumped more than 2, 000 gallons of red chemical fire retardant on a formerly pristine mountainside.

the technology has bestowed most of its benefits on agribusiness#almost always through crops modified to withstand weed-killing chemicals

Unlike Bt cotton and other existing GM organisms, such a crop would need no insect-killing chemical for protection from pests.

Based on previous work, the Japanese researchers sought to improve their cloning efficiency by using a chemical called trichostatin A that inhibits the powerful epigenetic protein histone deacetylase.

manipulate chemicals, fabricate materials and structures, produce energy, provide food, and maintain and enhance human health and our environment.

Scientists at the University of Michigan think they have a technology that emulates this process to display pictures without chemicals or electrical power.

When you look at a picture of a red flower on paper there is a pigment chemical that absorbs each color--green and blue for instance

it doesn't require any chemicals. Guo that said prints made this way would be permanent

The use of natural biodegradable products as an alternative to synthetic chemicals has shown remarkable improvements in maintaining fruit quality

Synthetic chemicals are used currently to control postharvest diseases but consumers worry about the chemical residues they leave on fruit their environmental impact

or blanching and most importantly using natural biodegradable products as an alternative to synthetic chemicals. Once proper postharvest technologies are used efficiently food losses can be minimised and the problem of food insecurity alleviated.

Cutting out the chemicals: Nature Newsozone experts are exploring ways to curb powerful greenhouse gases of their own making under the Montreal Protocol,

a network of experts worldwide and a 20-year track record of handling these types of chemicals.

We created these chemicals and we can get rid of them, says Durwood Zaelke, president of the Institute for Governance & Sustainable Development, an advocacy group in WASHINGTON DC.

We have the chemicals. We have the wherewithal within the treaty. It's just an administrative issue.

Emissions of some ozone-depleting chemicals will continue for some time and even in 2100 long-lived CFCS will remain the dominant ozone destroyers.

But schedules are in place to phase out most of the remaining chemicals of concern. The ozone story is winding to a close,

when analysing chemicals. And Fahey says Montreal's experts have performed well on that account. He co-authored a 2007 paper estimating that

depending on which chemicals fill the void. This is largely why the Montreal parties decided to weigh in on HFCS now.

The chemical giant Dupont, based in Wilmington, Delaware, is concerned more about industrial HFC refrigerants than incidental HFC by-products, for

better industrial processes and, ultimately, the development of new, more climate-friendly chemicals, says Mcfarland.

Chemicals in early refrigerants contributed to the hole in Earth's ozone layer-->Â See also Correspondence'Time running out to deal with banks of greenhouse gases

The US Environmental protection agency (EPA) has agreed to set new rules governing emissions of mercury and other toxic chemicals from power plants by November 2011,

Bisphenol A ban The European commission has agreed to ban the common chemical bisphenol A from baby bottles across the European union by mid-2011.

Another approach is to place the transgene under the control of a switch that must be activated by a proprietary chemical.

That would give companies control over the engineered trait by forcing buyers to return each year to purchase the chemical.

That is the strategy of Ginkgo Bioworks, a four-year-old synthetic biology company in Boston, Massachusetts, that develops made-to-order microbes to churn out marketable chemicals.

a genetic tweak that makes production of the desired chemical dependent on a proprietary additive, supplied by Ginkgo, in its fermentation medium.

and food safety groups are concerned about contamination of food crops with products from a new generation of crops engineered to produce chemicals or pharmaceuticals.

but the ecological and health effects of fertilizer chemicals raise serious concerns. China in particular, is facing a major pollution problem from overuse of nitrogen fertilizer,

mild chemicals known as ionic liquids can do the trick, as can harsh acids. But ionic liquids are generally expensive to make,

Chemicals! Technology! Big ag! The uncertainty of modern development! Like it or not most of what we eat in the U s. has been touched

That presented the possibility that those chemical and biological weapons could end up in the hands of terrorists;

and market authorizations for the thousands of chemicals and GM foods that were authorized on the basis of these studies should be revoked.

and other blood-making organsã¢Â#Âll of which are signs of severe toxicity. 3. This past year Food Chemical Toxicology published the results of a two-year study conducted by scientists at the University of Caen

and are forcing farmers to dump even more varieties of toxic chemical herbicides and pesticides on our foods in order to stay ahead of nature s race.

GMO corn contains an extremely high level of formaldehyde a chemical linked to adverse health effects and various forms of cancer.

People normally do a reaction purify the chemicals take the drug add it to cells look at the response formulate maybe do animals
