Last month, NASA's Dawn spacecraft began orbiting the 330-mile-wide rocky body of Vesta, the asteroid belt’s second-largest resident. The latest photos have been full of surprises, revealing extensive features, from multiple craters to mysterious grooves, that will keep scientists busy for years.
Graphite oxide has been a target for supercapacitor development for up to a decade, but prior to a recent breakthrough at Rice University nobody had been able to turn the material into a functional supercapacitor without adding chemicals. The researchers discovered a new phenomenon of GO, and were able to make the transition simply using heat.
An international team of scientists has amassed the largest data set to date on greenhouse gas emissions from hydroelectric reservoirs. Prior studies cautioned that these reservoirs could be a significant and large source of both carbon dioxide and methane to the atmosphere, but the new study claims the real output is just a fraction of previous estimates.
A biomedical engineering professor at Columbia University has spent that last four years testing his mobile microfluidic chip, or mChip, on hundreds of patients. The inexpensive chip requires a tiny finger prick of blood, and in less than 15 minutes delivers quantitative assays.
It may take more than willpower to stick to a diet. A researcher at the Albert Einstein College of Medicine has discovered what happens to the brain when the body is hungry, and it involves a bizarre process of autophagy, or self-eating.
The KiRay 100 from E Instruments is a non-contact, portable infrared thermometer that features a temperature range from -50 to 800 C. The device features adjustable emissivity and laser sighting.
The Hiden Analytical HPR60-EQP is a fully-integrated system configured specifically for measurement of atmospheric and near-atmospheric plasma and reactive processes in applications including analysis of atmospheric plasma jets (APD), dielectric barrier discharges (DBD) and flame chemistry.
This month's issue focuses on microscopy. Despite competition, the light microscope remains the most important instrument in the laboratory. And it's quickly evolving. The issue also looks at how companies are changing the way they organize their R&D functions and train staff for imaging applications and how confocal Raman imaging expands the possibilities for measuring large-scale samples. Other features include information on how simulation tools can answer design questions and take some of the mystery and risk out of R&D and how analysts focus on publication and citation data to reveal the size and structure of materials science research globally.
Brewster Kahle founded the nonprofit Internet Archive in 1996 to save a copy of every Web page ever posted. Now the MIT-trained computer scientist and entrepreneur is expanding his effort to safeguard and share knowledge by trying to preserve a physical copy of every book ever published.
University of Cincinnati researchers have developed the first lab-on-a-chip sensor to provide fast feedback regarding levels of the heavy metal manganese in humans. The low-cost, disposable invention is mercury-free and can deliver feedback within about 10 minutes.
A new optical coherence tomography technology developed by a Massachusetts Institute of Technology team has made it possible for users of endoscopy to see below the surface of the colon or esophagus to image microscopic pre-cancerous changes. Traditional screening methods were unable to offer this information.
Engineering software provider Ansys Inc. said Monday that it has completed its acquisition of Apache Design Solutions Inc. for $314 million in cash.Apache Design, a privately held company based in San Jose, Calif., specializes in designing simulation software for advanced, low-power solutions...
In a recent video clip, Massachusetts Institute of Technology PhD student Yang Zhang demonstrates the way water can stay in a supercooled state if there are no nucleation centers present to start the freezing process. His recent research has helped form a controversial new theory about water’s behavior.
After losing out to a consortium of technology companies during bidding for thousands of patents from the bankrupt Nortel, Google has bolstered its war chest with a collection of patents from IBM, one of the industry’s leading generators of intellectual property. The move has less to do with innovation than it does an effort to defend against lawsuits from other tech companies.
With the introduction of a new chlorine manufacturing process achieved by combining oxygen depolarized cathode technology and new electrolysis technology, Bayer MaterialScience is poised to save enough electricity to power a small city.
