While the automobile's total impact on the environment remains up for discussion, it's apparently pretty clear that cars and frogs don't really mix. Well, not if you're a male frog trying to get your croak on, at least. Scientists in Melbourne have found that due to traffic and machinery, a male frog's call can't be heard at great distances by female frogs. That's cutting down on the amount of frog sex to be had, and that, in turn, is cutting down on the number of frogs.
Yesterday, PhysOrg reported on the recently published fuel cell research of two Los Alamos scientists, Rajesh Bashyam and Piotr Zelenay, in the scientific journal Nature. Searching for a low-cost alternative to platinum, the duo developed a composite consisting of cobalt, polymer and carbon. The new catalysts weren't able to produce as much electrical energy as its platinum-based counterpart, however, the composite exhibited "exceptional performance stability" during a 100-hour test session.
