Fingerprints, ballistics, DNA analysis and other mainstays of the forensic science toolkit may get a powerful new crime-solving companion as scientists strive to develop technology for "fingerprinting" and tracing the origins of chemical substances that could be used in terrorist attacks and other criminal acts.
By harnessing quantum dots—tiny light-emitting semiconductor particles a few billionths of a meter across—researchers at the University of Washington (UW) have developed a new and vastly more targeted way to stimulate neurons in the brain.
Individual cells modified to act as sensors using fluorescence are already useful tools in biochemistry, but now they can add good timing to their resumé, thanks in part to expertise from the National Institute of Standards and Technology (NIST).
Life shrouds most choices in mystery.
Mapping the ancestry of sheep over the past 11,000 years has revealed that our woolly friends are stars among domestic animals, boasting vast genetic diversity and substantial prospects for continued breeding to further boost wool and food production for a rising world population.
When mature male white-crowned sparrows duel to win a mate or a nesting territory, a young bird just doesn't get much respect.
NSF Forum: The Challenge Of A Sustainable Future: Long-Term Ecological Research Offers New Answers
For coffee lovers, the first cup of the morning is one of life’s best aromas. But did you know that the leftover grounds could eliminate one of the worst smells around – sewer gas?
An international team of scientists led by University of Hawaiʻi at Mānoa oceanographer David Karl has documented a regular, significant and unexpected increase in the amount of particulate matter exported to the deep sea in the North Pacific Subtropical Gyre.
Scientists searching for the genomics version of the holy grail – more insight into predicting how an animal's genes affect physical or behavioral traits – now have a reference manual that should speed gene discoveries in everything from pest control to personalized medicine.
