Gut Microbes Can Split a Species 68

sciencehabit writes "The community of microbes in an animal's gut may be enough to turn the creature into a different species. Species usually split when their members become so genetically distinct — usually by living in separate environments that cause them to evolve different adaptations (think finches on different islands) — that they can no longer successfully breed with each other. Now researchers have shown that a couple groups of wasps have become new species not because their DNA has changed, but because the bacteria in their guts have changed — the first example of this type of speciation."

TSA Orders Searches of Valet Parked Car At Airport 453

schwit1 writes "Laurie Iacuzza walked to her waiting car at the Greater Rochester International Airport after returning from a trip and that's when she found it — a notice saying her car was inspected after she left for her flight. She said, 'I was furious. They never mentioned it to me when I booked the valet or when I picked up the car or when I dropped it off.' Iacuzza's car was inspected by valet attendants on orders from the TSA."

Honest question: Beyond "that's not the way it always has been", what is the problem with tabs on top?.

For those of us whose browse with many tabs open at once and frequently switch between them, tabs on top means a *lot* more mouse movement to accomplish this, which equals more time. Wasted time. It may not seem like much, but it is enough to be a noticeable delay, and adds up. Putting the tabs back where they belong solves this annoyance.

This may not be a factor depending on your own personal browsing habits.

Submission + - Google Wants You To Complete its U.S. Map (

azoblue writes: Google wants users to supplement Google Maps by adding local data with its Map Maker tool, which allows users to add to, annotate, and correct maps. Map Maker Pulse allows users to watch these edits in real time. A similar open project called has already been allowing users to edit maps for a few years.

Submission + - ABC, CBS, NBC block Google TV (

azoblue writes: The three major broadcast networks, uneasy about viewers bypassing cable and satellite providers — and the networks' own websites — to watch their TV shows, have begun blocking a new service from Google designed to make it easy to watch programming online. Can't help but wonder about the legality of this move and how fast the situation would change if Google simply returns the favor and blocks all ABC/CBS/NBC results from its search index.

Submission + - How DNA evidence creates victims of chance (

azoblue writes: Even when analysts agree that someone could be a match for a piece of DNA evidence, the statistical weight assigned to that match can vary enormously, even by orders of magnitude. For instance, in one man's trial the DNA evidence statistic ranged from 1/95,000 to 1/13, depending on the different weighing methods used by the defense and the prosecution.

Submission + - New evidence Mars rocks contain ancient fossils (

azoblue writes: NASA's Mars Meteorite Research Team reopened a 14-year-old controversy on extraterrestrial life last week, reaffirming and offering support for its widely challenged assertion that a 4-billion-year-old meteorite that landed thousands of years ago on Antarctica shows evidence of microscopic life on Mars.
