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."

Whatever Happened To Second Life? 209

Posted by Soulskill
from the i-blame-ralph dept.
Barence writes "It's desolate, dirty, and sex is outcast to a separate island. In this article, PC Pro's Barry Collins returns to Second Life to find out what went wrong, and why it's raking in more cash than ever before. It's a follow-up to a feature written three years ago, in which Collins spent a week living inside Second Life to see what the huge fuss at the time was all about. The difference three years can make is eye-opening."

Yellowstone Supervolcano Larger Than First Thought 451

drewtheman writes "New studies of the plumbing that feeds the Yellowstone supervolcano in Wyoming's Yellowstone National Park shows the plume and the magma chamber under the volcano are larger than first thought and contradicts claims that only shallow hot rock exists. University of Utah research professor of geophysics Robert Smith led four separate studies that verify a plume of hot and molten rock at least 410 miles deep that rises at an angle from the northwest."

Zombie Pigs First, Hibernating Soldiers Next 193 Screenshot-sm

ColdWetDog writes "Wired is running a story on DARPA's effort to stave off battlefield casualties by turning injured soldiers into zombies by injecting them with a cocktail of one chemical or another (details to be announced). From the article, 'Dr. Fossum predicts that each soldier will carry a syringe into combat zones or remote areas, and medic teams will be equipped with several. A single injection will minimize metabolic needs, de-animating injured troops by shutting down brain and heart function. Once treatment can be carried out, they'll be "re-animated" and — hopefully — as good as new.' If it doesn't pan out we can at least get zombie bacon and spam."

How Best To Deal With WiFi Interference? 451

Posted by Soulskill
from the all-it-takes-is-one-EMP dept.
marciot writes "I live in a condominium where I get interference from my neighbors' WiFi. I understand that 1, 6 and 11 are the only non-overlapping WiFi channels, but how does this translate into real-life best practices? When you must overlap, is there a 'good' way to do it? With nine access points, for example, is it better to have three APs each on 1, 6 and 11, so that each completely overlaps with only two others? Or is it best to distribute those APs across nine channels such that they only partially overlap others (but potentially overlap more APs in total)? Do use patterns affect interference? For example, is it best to overlap a channel with multiple APs that rarely transfers data, or to share a channel with one person who downloads torrents 24/7? Does maximum data rate affect interference or robustness to interference? I found out by accident that setting my access point to '802.11b only' mode appeared to give me a vastly more reliable connection that leaving it in 'mixed 802.11b/g.' Is this a fluke? Or does transmitting at 10 Mbps when everyone else is using 54 Mbps (for their 3 Mbps DSL pipes!) give you a true advantage?"

+ - How to tell if your Xbox 360 will break->

fdmendez writes "In reality there's no 100% sure way to tell if you're Xbox 360 is going to break, but you can find out if you're machine is one of the consoles likely to go sour.

Here's how it breaks down: In response to a staggering rate of failure for the 360, Microsoft decided to fix the heat sink issue with its console. The earlier Xbox 360s tend to lack the new heat sink, and the older Xbox 360s tend to have the new heat sink.

If you're console doesn't have the new heat sink, there's a good chance you're going to witness the red ring of death soon, but, if you're curious as to whether your 360 has the new heat sink, Ben Heck has the deets on how to tell without voiding your warranty and all you need is a digital camera."
