The University of Cincinnati researchers have created a novel microsensor for monitoring radioactive and hazardous wastes in the Hanford nuclear facility. The sensor offers three-way selectivity and high sensitivity, allowing it to detect compounds at the nanomolar level.
A new DNA vaccine has been developed to protect North American salmon and trout farms from a major disease, with successful trials showing 90% reduction in mortality. The vaccine works by introducing DNA containing the gene for one of the viral proteins, which is then taken up by cells and produces the protein to prime the immune system.
Physicians at Massachusetts General Hospital have successfully induced a state of immune tolerance in a patient, allowing her to discontinue immunosuppressive drug treatment without rejecting a transplanted kidney. The breakthrough approach, known as mixed chimerism, has the potential to revolutionize organ transplantation for thousand...
Researchers have found detectable levels of tributyltin in Gulf oysters, which can be toxic to crustaceans. Additionally, the Mississippi River has shown improvement in water quality, with a decrease in volatile organic compounds detected since 20 years ago.
Scientists have discovered that naturally occurring fatty acids can help prevent vascular inflammation, a key component in the development of atherosclerosis. The NIEHS-cloned gene produces an enzyme that makes these fatty acids, which can suppress inflammation and protect against heart disease.
Sixty experts agree that half of the world's turtle species are at risk of extinction due to human consumption. The main causes of decline are linked to ecological change, while exploitation drives 50% of threatened turtles to extinction.
Near-critical water, which can dissolve both salts and non-polar organic compounds like oils, is being studied as a replacement solvent in various chemical processes. This could lead to the elimination of hazardous solvents and salt byproducts, reducing environmental impact.
A study presented at the American Chemical Society meeting found that high-temperature drying in clothes dryers can cause serious abrasions and cracking damage to cotton fabrics. This results in reduced fabric strength, faster wear-out, and increased lint production.
Researchers at Cornell University have developed a method to switch the orientation of magnetic domains in thin layers, allowing for the creation of high-density computer memory chips. The effect works by passing an electric current through a 'sandwich' of cobalt and copper layers, resulting in non-parallel magnetic moments.
Actuaries forecast a low probability of a national health plan being implemented by 2010 and 2050. The US suicide rate is expected to rise, with Americans born in 1997 predicted to live beyond age 80 by 2050.
Scientists are creating tiny 'motes' of 'smart dust' that can communicate with each other and sense their environment, paving the way for a range of applications including weather monitoring and espionage. The devices use optical transceivers to minimize power consumption and have already demonstrated monitoring capabilities over 21 ki...
A taste test by University of Missouri researchers found no significant difference in the flavor of low-fat and regular chocolate ice cream due to its unique mix of chemicals that make up its distinctive flavor. The study suggests that this complexity helps mask off flavors, resulting in a similar taste experience for both versions.
A study of 182 Oklahoma City bombing survivors revealed high rates of postdisaster psychiatric disorders, with 45% experiencing symptoms in the six months following the explosion. The investigation also identified specific symptoms that indicated the need for treatment, including avoidance and numbing symptoms.
Researchers at Georgia Tech are using MRI to study textile drying and moisture flow in carpets, with potential benefits including faster drying times, reduced energy consumption, and less prone to mildew. The technique also allows for the analysis of fabric structures and wicking of sweat away from the body.
Computer scientists at Brandeis University have successfully designed and built various LEGO structures, such as bridges and cranes, without human input. The team's program uses a trial-and-error approach to optimize designs based on simple optimization goals, laying the groundwork for robots capable of reworking their own hardware.
A recent study found that mosquito fish preferentially eat tadpoles over mosquito larvae, leading to the decline of various frog and newt species. This ecological disaster may be linked to the widespread introduction of these fish as a form of biological control in the early 20th century.
