Scientists have designed a quick method for detecting counterfeit perfumes, and have tested it on major brands like Givenchy, Hermes and D&G.
Oxygen appeared in the atmosphere up to 700 million years earlier than previously thought, according to research that raises new questions about the evolution of early life.
New nanotechnology uses non-biodegradable plastic grocery bags to make carbon nanotube membranes- highly sophisticated and expensive materials with a variety of potential advanced applications including filtration, sensing, energy storage and a range of biomedical innovations.
New research that looked at whether two commonly prescribed statin medicines— used to lower “bad cholesterol” levels in the blood— can adversely affect cognitive function has found that one of the drugs tested caused memory impairment in rats.
Using a particular type of titanium dioxide— a common ingredient in cosmetics, food products, toothpaste and sunscreen— could reduce the potential health risks associated with the widely used compound.
New nanoparticles soak up underwater oil like millions of tiny sponges and remove it from the environment. Each "nanosponge" is 100 times thinner than a human hair and can hold more than 10 times its own weight in oil.
A class of flame retardants that has been linked to learning difficulties in children has rapidly declined in pregnant women’s blood since the chemicals were banned in California a decade ago.
The high oxygen content of biomass components pose a problem. But researchers have now introduced a process based on a tandem reaction that could reduce the oxygen content of both lignin and bio-oils under unusually mild conditions.
The world's second largest hamburger chain is launching a new crinkle-cut french fry, called “satisfries,” today that it says has about 20 percent fewer calories than its regular french fries.
A report urges doctors to push for stricter environmental policies to better identify and reduce exposure to chemicals that prove truly risky. But it's likely to scare pregnant women in the meantime.
Scientists have published two papers in an academic journal this week that unlock mysteries of a chemical process upon which all life on earth depends.
A brighter, better, longer-lasting dental implant may soon be on its way to your dentist's office. A nano-material can battle infection, improve healing and help dental implants last a lifetime.
Researchers have created the first theoretical framework that includes the molecular-level structural inhomogeneity seen in polymers, seeking to understand, predict and improve the conductivity of semiconducting polymers.
Acetals are chemical compounds found in many wines, like port, for example, which give it a unique, sweet smell. However, if acetals are blended with biodiesel, they improve its properties.
It is often said that once people develop an addiction, they can never completely eliminate their attraction to the abused substance. Now, a study suggests that even long-term abstinence from cocaine does not result in a complete normalization of brain circuitry.
Researchers have identified the site where the widely used anesthetic drug propofol binds to receptors in the brain to sedate patients during surgery. Researchers believe the finding eventually will lead to the development of more effective anesthetics with fewer side effects.
The American Thoracic Society has demanded that FDA move forward with proposed rules to bring cigars, e-cigarettes and other tobacco products under FDA federal regulation.
Toxic metals from the only open pit mine in an estuary system in the U.S. are widespread in nearby sediment, water and fish, and may be affecting marine and coastal animals that feed on them beyond the mine site.
Researchers are using a new approach to fighting antibiotic-resistant bacteria: targeting the cell membranes of MRSA— a bacteria responsible for increasing the number of life-threatening infections both in hospitals and communities.
A lightweight metal that reduces fuel use in cars and planes could be extracted from the ocean through a unique process. The process could ultimately make fuel-efficient transportation more affordable and expand the American magnesium market.
A Utah sheriff traveled to Florida and helped arrest a man in an 18-year-old murder case after authorities say they used DNA from a cigarette butt to link him to the crime.
Most hydrophobic materials have limited durability, especially in steamy industrial settings. A new approach to coating condenser surfaces should overcome that problem.
People given a choice between generic or branded drugs should look closely at the ingredients in the drug they are buying, argue economists.
NASA's Curiosity rover hasn't discovered any signs of methane in the atmosphere of Mars, a finding that does not bode well for the possibility that microbes capable of producing the gas could be living below the planet's surface.
A new study shows that in nanoscopic channels, the effective viscosity of water in channels made of glass can be twice as high as water in plastic channels. Nanoscopic glass channels can make water flow more like ketchup than ordinary H2O.
