...tory instruments. Rugged and portable, the Mini 10 weighs about 22 pounds -- 30 times less than a conventional mass spectrometer -- and uses about as much battery power as a laptop computer. "This instrument has evolved from a decade-long experimental and simulation program in mass spectrometer miniaturiz...Ancient raptors likely feasted on early man, study suggests
...he size of an American bald eagle, which typically weighs about 10 to 12 pounds. Punctures and scratches on many of the monkey skulls have led some researchers to rethink which animals may have preyed on our human ancestors, said W. Scott McGraw, the study's lead author and an associate professor of anthro...Images develop clinical applications for new DESI technology
...echnology. It is roughly the size of a shoebox and weighs about 40 pounds, compared to around 600 pounds for a conventional mass spectrometer. The portable instrument runs on batteries and can be carried anywhere, allowing the technology to more easily be used for field applications like explosives detectio...New technique boosts size of proteins that can be analyzed
...issociate the protein. Next, the mass spectrometer weighs any surviving protein and its pieces simultaneously. The top-down approach rivals the commonly used "bottom-up" approach, in which proteins are first broken down, or digested, enzymatically into smaller units of five to 20 amino acids. These pieces a...Story tips from the Department of Energy's Oak Ridge National Laboratory, October 2006
...TION -- Ultralight transit bus . . . A bus that weighs half as much as conventional buses, boasts three times the fuel economy and can carry 20 percent more passengers could debut by the middle of next year. At the heart of the bus is an ultra-high-strength stainless steel body and chassis that would act...Complexity constrains evolution of human brain genes
...chimpanzees, our closest relative, the human brain weighs 250 percent more. How such a massive morphological change occurred over a relatively short evolutionary time has long puzzled biologists. Previous reports have argued that the genes that regulate brain development and function evolved much more rap...Is there a pilot in the insect?
...t based on this principle. The most recent version weighs only 0.2 grams. This is the neuron that does most of the work on board the microhelicopter. The optic flow regulator helps explain how an insect manages to fly, even in unfavorable wind conditions, without measuring its ground height, groundspeed or ...National panel led by LSU Chancellor releases report on Corps of Engineers
...ployed by the Corps rely on a priority system that weighs the relative economic value of a project against its actual cost. In order for a project to be launched, its "benefit-cost" ratio has to reach a certain level. The panel suggests that this narrow focus to the process is inadequate and must be broaden...QUT microgravity tower attracts global scientific community
...rchers can pay huge fees to run an experiment that weighs just several kilograms in the space shuttle whereas the QUT facility will cost far less per drop. We can also perform many drops per day and the experimental system being used can weigh hundreds of kilograms and be quite large. Professor Steinber...Camera-shy deer caught for first time
...nds approximately 25-30 inches tall (65-80 cm) and weighs up to 110 pounds (50 kilograms). Its namesake antlers are significantly larger than other muntjac species found in Indochina. The photographs were taken using camera traps set in Laos Nakai Nam Theun National Protected Area (NNT NPA), in the Annam...... The end result is a device that looks, feels, and weighs the same as paper. The creation of this unique nanocomposite paper drew from a diverse pool of disciplines, requiring expertise in materials science, energy storage, and chemistry. Along with Linhardt, authors of the paper include Pulickel M. Ajaya...
