Replacing a Genome Boosts Race to Develop Designer Bugs: Study

...or biofuels, cleaning up toxic waste, sequestering carbon or other applications. It "is a landmark in biological engineering taking us from moving one gene or a set of genes to the ability to move an intact genome," said Barbara Jasny, deputy editor of the journal Science, which first reported the experim...

Shisha Owners Mobilise Against July 1 Smoking Ban in England

...e smoker is exposed to larger amounts of nicotine, carbon monoxide and certain other toxins than the typical cigarette smoker. It points out that the force needed to pull the air through the hose allows the smoke to reach much deeper into the lungs. Several experts said a smoker absorbs 200 times more s...

...the structure of the bread dough. Gluten holds the carbon dioxide (CO2) produced by the yeast and expands during fermentation, and provides the elasticity and extensibility (stretch) in bread dough. Glutenin and gliadin are the two proteins that form gluten. Gluten is generally found in rice, wheat and ba...

Deforestation Plays a Critical Role in Climate Change: Study

... in the tropics accounts for nearly 20 per cent of carbon emissions due to human activities. This will release an estimated 87 to 130 billion tonnes of carbon by 2100, which is greater than the amount of carbon that would be released by 13 years of global fos...

Scientists Saying Against Trees Sparks Debate

...ing plants in an atmosphere saturated with a heavy carbon isotope, 13C. If the plants subsequently emitted methane (13CH4), it would be easy to spot above the background of light (12CH4) methane in the air. Photo-acoustic spectroscopy (a laser-based measuring technique) was used to detect the gas. Dueck...

Smokeless Cannabis Delivery Device Found Efficient and Less Toxic
