Submission + - Comet Lovejoy Plunges into the Sun and Survives (nasa.gov)

boldie writes: "NASA has a Story about a comet Lovejoy's close encounter with the sun.

This morning, an armada of spacecraft witnessed something that many experts thought impossible. Comet Lovejoy flew through the hot atmosphere of the sun and emerged intact.

"It's absolutely astounding," says Karl Battams of the Naval Research Lab in Washington DC. "I did not think the comet's icy core was big enough to survive plunging through the several million degree solar corona for close to an hour, but Comet Lovejoy is still with us."

The comet's close encounter was recorded by at least five spacecraft: NASA's Solar Dynamics Observatory and twin STEREO probes, Europe's Proba2 microsatellite, and the ESA/NASA Solar and Heliospheric Observatory. The most dramatic footage so far comes from SDO, which saw the comet go in (movie) and then come back out again (movie).

NASA's Solar Dynamics Observatory caught Comet Lovejoy emerging from its scorching close encounter with the sun. [Entrance movie: Quicktime (22 MB), m4v (0.8 MB)] [Exit movie: Quicktime (26 MB), m4v (0.8 MB)]

Submission + - New lab zaps aircraft with lightning bolts (networkworld.com)

coondoggie writes: "A new laboratory has opened that will study the impact of lightning strikes on airplanes, particularly new aircraft that are made up of carbon composite materials. The $2.5 million Morgan-Botti Lightning Laboratory at Cardiff University in the UK says its facilities will generate up to 200,000 Amps. "To put this in context, an average lightning strike has 32,000 Amps and the maximum amount of electricity powering a house is about 100 Amps," the University stated."

Submission + - The Food and Drug Terror Headache is Hardly Over (motherboard.tv)

CoveredTrax writes: "To coincide with today's Senate subcommittee hearing on agro-defense and new reporting that the Department of Defense's food anti-terror plans are costly, unwieldy and otherwise fractured, Motherboard takes an in-depth look at the 1982 Chicago Tylenol killings, far and away the most chilling act of American terror you've never heard of."

Submission + - Windows 8: full details revealed (pcpro.co.uk) 1

Barence writes: Microsoft has released the first full details of Windows 8, with an all-or-nothing approach to touchscreen technology. All versions of Windows 8 — whether used on a touchscreen device or not — will use the operating system's new Metro interface, which was first developed for Windows Phone 7 devices. The advent of Windows 8 sees Microsoft introduce a new style of application, dubbed Metro Style apps, and its own app store. The company also claims to have boosted Windows 8 performance with fast boot/shutdown times, a new Task Manager and the option to Refresh a PC with a clean install of the OS with apps and setting still left intact.

Submission + - World's Oldest Fossils Found on Australian Beach (sciencemag.org)

sciencehabit writes: Researchers say they have discovered the fossils of 3.4-billion-year-old cells in between the cemented sand grains of an ancient beach in Western Australia , possibly the oldest fossils ever found. Chemical analyses of the minerals near the cells suggest the microorganisms depended on sulfur for fuel. Such a beach might have been life's first breeding ground, one author says.

Submission + - Boeing Demonstrates Aircraft Swarming Technology (gizmag.com)

Zothecula writes: Individually, insects have proven a deep well of inspiration for robotics engineers looking to mimic designs refined over millions of years of evolution. Now Boeing has demonstrated swarm technology for reconnaissance missions using unmanned aerial vehicles (UAVs) that is similar to the way insects communicate and work together as an intelligent group. Potential uses for the technology include search-and-rescue missions and identifying enemy threats ahead of ground patrols.

Comment Good...easy...free software? (Score 1) 99

I am a teacher (former geek) and I have struggling to find good timelining software for use by both me and my students...my needs are:

A. Must be free
B. Easy to add events
C. Exportable to a file
D. Multiple user support would be nice

Simile Timeline looks nice but is certainly not easy, and probably requires more skill to implement than I am capable of. Plus, I don't have a server to run it on. Timeglider are Timerime look fine as easy to use software, but are ultimately commercial services and I suspect will ultimatly cause problems. Anyone have any suggestions? Non-web based freeware is also fine, but it needs to be free so I can have students use it as well. That would also pretty much mandate Windows as well. An suggestions would be dandy. Thanks!
