plastics
A team of pioneering South Korean scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals.
A study of 145 preschool children reports, for the first time, that when the concentrations of two common phthalates in mothers' prenatal urine are elevated their sons are less likely to play with male-typical toys and games, such as trucks and play fighting.
The University of Rochester Medical Center-led study is published in the International Journal of Andrology.
November 11, 2009 (Oakland, Calif.) -- High levels of workplace exposure to Bisphenol-A may increase the risk of reduced sexual function in men, according to a Kaiser Permanente study appearing in
ATHENS, GA -- Air quality in homes, offices, and other indoor spaces is becoming a major health concern, particularly in developed countries where people often spend more than 90% of their time ind
Exposure to a combination of excess stress hormones and chemicals while in the womb could affect a man's fertility in later life, a study suggests.
The century-old challenge of transporting acetylene may have been solved in principle by a team of scientists working at the National Institute of Standards and Technology (NIST). A NIST research team has figured out* why a recently discovered material can safely store at low pressure up to 100 times as much of the volatile chemical as can be done with conventional methods.
If anybody is thinking of updating the 1967 hit movie, The Graduate, they need to consider making a one-syllable change in the dialog. When the guy whispers in Dustin Hoffman’s ear, he needs to say: “One word. (pause) Bioplastics!" Yes, plastic made from natural polymers appears to be getting a second wind.
WASHINGTON, Aug. 16, 2009 -- In the first study to look at what happens over the years to the billions of pounds of plastic waste floating in the world's oceans, scientists are reporting that plastics -- reputed to be virtually indestructible -- decompose with surprising speed and release potentially toxic substances into the water.
WASHINGTON, Aug. 16, 2009 -- Cleaning oily smears from kitchen countertops, mirrors, garage floors, and other surfaces with plain water -- rather than strong detergents or smelly solvents -- may seem like pure fantasy. But scientists in Indiana today describe what they believe to be a simple and effective state-of-the-art oil stain remover.
RICHLAND, Wash. -- The newest supercomputer in town is almost 15 times faster than its predecessor and ready to take on problems in areas such as climate science, hydrogen storage and molecular chemistry.
Advanced composite materials are playing a vital role in improved design and reduced operating costs for renewable energy technologies. Research presented today [Tuesday 30 June] will highlight how wind, marine and solar power could address these challenges within the renewable energy industry.
In revisiting a chemical reaction that's been in the literature for several decades and adding a new wrinkle of their own, researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass.
A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system could answer questions about how life could emerge.
Exposure to dioxins during pregnancy harms the cells in rapidly-changing breast tissue, which may explain why some women have trouble breastfeeding or don't produce enough milk, according to a University of Rochester Medical Center study.
