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."

jshamacher writes "I've used MythTV for several years (first on Slackware, now via Mythbuntu) and it's good. But not great — I have a list of annoyances as long as my arm. For example, even 0.22 still has problems playing many DVDs and I frequently have to fall back on Xine. Since upgrading to new hardware, I've had issues with sound dropping out; these problems only occur for Myth, not for anything else. So now I'm trying out alternatives. Freevo seemed promising when I tried it a few months ago but it had its own issues. I'm also increasingly getting pressure from my family to get things like NetFlix streaming working on this machine. This seems to imply migrating to a Windows-based solution. I threw XP on it and tried MediaPortal but could never get that to control my Motorola cable box via the IR blaster. So my questions to you: What DVR software do you use? Are you happy with it? What don't you like? Are there any packages out there that 'just work' as media hubs and for time-shifting cable TV?"

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

At the Ohio LinuxFest yesterday, two Linux geeks were married — or had their projects merged into a single trunk, as the officiant, Lord Drachenblut, put it. The wedding of Randy Noseworthy (proprietor of the Juiced Penguin) and Janet Edmonson was announced last week and was live-tweeted by at least one attendee — here's his photo of the happy couple. There's also a video of the ceremony, at which Jon "Maddog" Hall offered a blessing via pre-recorded audio.
Update: 09/26 20:03 GMT by KD : In the comments, anyaristow notes that this wasn't the first such wedding; Rob Landly and Fade were married at Penguicon in 2007, with Steve Jackson officiating and Eric Raymond as best man.

webdoodle writes "A new study finds that a change in a single gene has sent two closely related bird populations on their way to becoming two distinct species. The study, published in the August issue of the American Naturalist, is one of only a few to investigate the specific genetic changes that drive two populations toward speciation."
