Marsh-dwelling mole gives new meaning to the term 'fast food'
...t as its brain and nervous system will allow. They calculate that when a mole touches a new object, its brain has about eight milliseconds to determine whether it is edible. Given the split millisecond timing involved, it is not surprising that the moles frequently make mistakes. In a series of trials where th...Hummingbirds lose power at high altitudes
...requency and stroke amplitude, from which he could calculate the power exerted in normal hovering. The second experiment, however, measured the maximum power the birds' muscles were capable of. In a setup originally developed by Dudley and former post-doc Peng Chair, he attached a string of eve...Study in Royal Society journal on possible genetic factors in social responsiblity
...hat provides a systematic approximation to quickly calculate and reduce the drag associated with shock waves generated by wings travelling near the speed of sound. The method uniquely allows us to do the complete design on a small personal computer as contrasted to supercomputers. It gives a very precise recip...People cause more soil erosion than all natural processes
...n sedimentary rock distributions and abundances to calculate rates of natural erosion. "If you ask how fast erosion takes place over geologic time---say over the last 500 million years---on average, you get about 60 feet every million years," Wilkinson said. In those parts of the United States where soil is ...Hurricane Ivan helps student study sinkholes
...ray. "If you know the voltage and current, you can calculate the resistance," Schwartz said. Different degrees of electrical resistance allows him to identify water, rock, soil, and voids to a depth of about 15 meters and create a model of the subsurface. Schwartz may also be able to determine the water's che...Iraqi civilian deaths increase dramatically after invasion
...s. The survey is the first country-wide attempt to calculate the number of civilian deaths in Iraq since the war began. The United States military does not keep records on civilian deaths and record keeping by the Iraq Ministry of Health is limited. The study is published in the October 29, 2004, online editio...Mail-order drugs exposed to extreme heat become less effective
...er tube pre- and postdispensation were obtained to calculate simulated drug delivery. Results showed that filter weights of heated medications were less than half of those unexposed to heat, showing that a significantly less amount of the drug had been dispensed after it had been heated. In addition, capsule...Predicting infection risk of mosquito-borne disease
...thematical models can help public health officials calculate risk of infectious diseases in heterogeneous environments--that is, real world conditions--when vector ecology and the parameters of transmission are well characterized. Any plan to prevent and control the spread of mosquito-born infections would cle......ullet. As a particle passes by two lasers, sensors calculate its exact speed and tell the LAMS when to fire a third, high-powered laser that vaporizes a portion of the particle, sending fragments hurtling along a "flight tube". Lighter molecules take less time to travel down the flight tube, giving the researc...
