Government to speed tracking of E. coli in meat

A new Agriculture Department program will begin tracing the source of potentially contaminated ground beef as soon as there is an initial positive test. Current procedures require USDA officials to wait until additional testing confirms E. coli before starting their investigation. Under the new process, the source could be traced 24 to 48 hours sooner.

Sensor tests fruits' ripeness

Every year, U.S. supermarkets lose roughly 10% of their fruits and vegetables to spoilage, according to the Department of Agriculture. To help combat those losses, Massachusetts Institute of Technology chemistry professor Timothy Swager and his students have built a new sensor that could help grocers and food distributors better monitor their produce.

Climate change may create price volatility in the corn market

In a study from Stanford University and Purdue University, researchers have shown for the first time that climate change may force the U.S. corn belt to move north in the next 10 years, escaping devastating heat waves. In turn, this will bring substantial price swings to the corn market, adversely affecting industries like food and biofuels.

FDA issues draft guidance on nanotechnology

The U.S. government has issued its initial draft guidelines on the use of nanotechnology, particularly nanoparticles, in food and cosmetic products. These recommendations, intended to help guarantee consumer safety within these two industries, do not extend to the other products that fall under Food and Drug Administration oversights, such as drugs and medical devices.

FDA wants limits on antibiotics given to animals

Antibiotics are mixed with animal feed to help livestock, pigs and chickens put on weight and stay healthy in crowded barns. Scientists have warned that this routine use leads to the growth of antibiotic-resistant germs that can be passed to humans. Now the Food and Drug Administration is weighing in on the matter, calling on drug companies to help limit the use antibiotics.

Red wine, fruit compound could help block fat cell formation

A compound found in red wine, grapes, and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a Purdue University study.

Carbon nanotubes can double growth of cell cultures

According to recent first-of-its-kind research results, a dose of carbon nanotubes can more than double the growth rate of plant cell cultures. Previous work at the University of Arkansas showed that multi-walled carbon nanotubes can penetrate the thick coatings of seeds. It turns out they can also stimulate germination and growth in plant cell cultures.

Coffee may cause high achievers to slack off

While stimulants may improve unengaged workers' performance, a new University of British Columbia study suggests that for others, caffeine and amphetamines can have the opposite effect, causing workers with higher motivation levels to slack off.

Agilent, FDA collaborate to improve testing for salmonella

Agilent Technologies Inc. announced that it has entered into a Cooperative Research and Development Agreement with the United States Food and Drug Administration to develop new tools to detect and analyze pathogens in food.

President proposes national network for manufacturing innovation

After touring the Rolls-Royce Crosspointe jet engine disc manufacturing facility in Prince George, Va., on March 9, President Obama announced his intention to build a network of up to 15 manufacturing innovation institutes to serve as regional hubs of manufacturing excellence. The move is intended to make U.S. manufacturers more competitive and encourage investment.
