grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

Slatterz writes "Apple co-founder Steve Wozniak, better known in the industry as 'Woz,' believes that the iPod is on its way out and has revealed his discomfort with some aspects of the iPhone. Wozniak said that the iPod has had a long time as the world's most popular media player, and that it will fall from grace due to oversupply. Wozniak also commented on the iPhone's proprietary nature and locked service provider, and compared it to Google's open Android platform. 'Consumers are not getting all they want when companies are very proprietary and lock their products down,' he said. 'I would like to write some more powerful apps than what you're allowed.'"

aaandre writes with word of a Washington Post story which begins: "The Maryland State Police classified 53 nonviolent activists as terrorists and entered their names and personal information into state and federal databases that track terrorism suspects, the state police chief acknowledged yesterday. The police also entered the activists' names into the federal Washington-Baltimore High Intensity Drug Trafficking Area database, which tracks suspected terrorists. One well-known antiwar activist from Baltimore, Max Obuszewski, was singled out in the intelligence logs released by the ACLU, which described a 'primary crime' of 'terrorism-anti-government' and a 'secondary crime' of 'terrorism-anti-war protesters.'" According to the article, "Both [former state police superintendent Thomas] Hutchins and [Maryland Police Superintendent Terrence] Sheridan said the activists' names were entered into the state police database as terrorists partly because the software offered limited options for classifying entries." Reader kcurtis adds "The State Police say they are purging the data, but this is one more example (on top of yesterday's news that datamining for terrorists is not feasible due to false positives) of just how badly the use of these lists can be abused."

An anonymous reader writes "US News makes a mint off its college rankings every year, but do they really give meaningful information? A pair of mathematicians argues that the data the magazine uses is all likely to be at least somewhat relevant, but that the way the magazine weights the different statistics is pretty arbitrary. After all, different people may have different priorities. So they developed a method to compute the rankings based on any possible set of priorities. To do it, they had to reverse-engineer some of US News's data. What they found was that some colleges come out on top pretty much regardless of the prioritization, but others move around quite a lot. And the top-ranked university can vary tremendously. Penn State, which is #48 using US News's methodology, could be the best university in the country, by other standards."

Roland Piquepaille writes "A Stanford University team has developed a microscope weighing only 1.1 grams. It is so small that it can be mounted to the head of a freely moving mouse to watch its brain cell activity. According to what the lead researcher told New Scientist, 'A lot of work has been done using brain slices, or anaesthetised animals — even using animals that are awake but restrained. But so far it has been impossible to image cellular-level activity in a freely moving mouse.' Not any more. And as mice are the 'preferred' animals in medical labs, this new kind of microscope could lead to new ways to study human diseases."
