Bacteria are a pervasive and elusive bunch. Scientists estimate that between 10 million and 1 billion different microbial species populate the world, yet only a handful of them have so far been identified. Why? Because the overwhelming majority of microbes refuse to grow in the laboratory. This is despite decades of scientists’ best efforts at coaxing the microscopic organisms into action.
A forensics investigator dusts a crime scene for fingerprints. When she finds one, she reaches to her holster, pulls out a handheld device, and aims it at the fingerprint. The device captures the image and also the chemical composition. That chemical analysis reveals that the person who left the print had touched ephedrine—an illegal drug, which is a stimulant that goes by many street names, including meow. With this information, the investigators can use biometrics—the fingerprint— to identify the person and the chemical analysis to start piecing together the crime.
Support for researchers performing mutation detection and genome editing.
The University of Adelaide has been awarded more than $3.8 million by the Australian Research Council (ARC) to collaborate with industry on a range of projects spanning fields such as computer science, genetics, agriculture, engineering, communications, physics and the environment.
For the ever-shrinking transistor, there may be a new game in town. Cornell University researchers have demonstrated promising electronic performance from a semiconducting compound with properties that could prove a worthy companion to silicon
Sir Isaac Newton probably wasn’t thinking about how animals urinate when he was developing his laws of gravity. But they are connected – by the urethra, to be specific.
Deliberate practice may not have nearly as much influence in building expertise as we thought, according toresearch published in Psychological Science, a journal of the Association for Psychological Science.
Could playing video games help people understand and address global sustainability issues such as pollution, drought or climate change? At least two researchers believe so, outlining their argument in a concept paper published in the journal “First Monday.”
The Chinese herb thunder god vine (Tirpterygium wilforii) has been shown to suppress GRP78, eventually leading to pancreatic cancer cell death according to University of Minnesota researchers.
Following a thorough damage assessment, the SLAC National Accelerator Laboratory had restored power to the linear accelerator. All safety systems and fire suppression systems have been restored. SLAC will start up accelerator operation and resume operations at both LCLS and FACET, according to the lab's website. The fire had shut down the lab as of late Thursday, June 28, but there were no injuries and no danger to the community, the university said in a statement.
Scientists have found how the electric fish evolved its jolt.
Researchers at the University of California, San Diego School of Medicine have discovered a widely distributed group of marine bacteria that produce compounds nearly identical to toxic man-made fire retardants.
