“An 8.9-magnitude earthquake hit off the east coast of Japan early today. The quake — one of the largest in recorded history — triggered a 23-foot tsunami that battered Japan’s coast, killing hundreds and sweeping away cars, homes, buildings, and boats. (43 photos total)
“Reconstructing the anatomy of prehistoric sharks isn’t easy. With few exceptions – an exquisitely-preserved body fossil here, some calcified bits of skeleton there – teeth make up the majority of the shark fossil record.
When those teeth come from a relatively recent species with close living relatives, it is not difficult to imagine what the extinct species might have looked like. The further back in time you go, though, the more bizarre sharks become. Sometimes teeth are not enough, and one especially unusual set of teeth has vexed paleontologists for over a century.
At first sight, the teeth didn’t look like they belonged to a shark at all. Coiled upon itself in a circular whorl, the bizarre tooth row superficially resembled the shells of extinct cousins of nautilus and squid called ammonites.
After studying tooth whorls found in the Ural Mountains, though, the Russian geologist Alexander Petrovich Karpinsky recognized them for what they were. In 1899 he described them under the name Helicoprion as the remains of an ancient shark. Just how they fit in the shark’s mouth was another matter altogether.”
“A 8.9 magnitude earthquake hit Japan today at 12:46am EST, the largest ever suffered by Japan and among the world’s Top 10.
Thousands of videos are pouring in, as the country stands still in the middle of disaster.
Here’s a summary of all that is happening, from a round of home videos updating in real time to the emergency nuclear shutdown, going through giant whirlpools and giant waves of mud and flames.”
“A six month journey along the 2,200 mile long Appalachian Trail, condensed and reinterpreted into five minutes of stop-motion.”
“We were traveling through Africa. We had music on iPods but no way to share the music. We needed something that was small, light, could be taken with us easily, and didn’t require any power.
An idea sparked when traveling soon became a fun side project around our day jobs. Our goal was to create a product that was thoughtfully designed, sustainable, and built from superior materials. After several prototypes we are really happy with the quality, ease of use, and functionality of Tembo Trunks.
Tembo Trunks are the speakers that aren’t speakers. They are the first collapsible earbud speakers for iPods and iPhones.
All you need to do is attach your Apple earbuds to Tembo Trunks in order to transform them into a set of portable, non-electrical, virtually indestructible stereo speakers. Amplify your tunes. Anywhere. Anytime.”
“Two backups are better than one. It’s the only principle geeks follow more closely than the Prime Directive.
Back up your data to one drive, and make the second drive into an exact duplicate of the first — voila, a backup of a backup. In IT parlance, this is known as a redundant backup, and the most popular system for handling it is called RAID, or Redundant Array of Independent Disks.
The PopDrive from DHK Storage intends to be one of the first inexpensive, consumer-level RAID drives. It comes with two separately packaged, Western Digital 2.5-inch hard drives, like those found in notebooks. The package with two 500-GB hard drives will cost you $250, for two 750-GB drives, you’ll pay $350.
You also get both a USB 2.0 cable and an eSATA cable. The drives, which pop into the two retractable slots on the PopDrive’s aluminum case, are hot swappable when using the eSATA cable, but not when using USB. Unfortunately, most computers these days don’t have the faster eSATA ports, but for those that do, the throughput performance is blazingly fast — you’ll get 3 gigabits per second over eSATA versus USB 2.0’s 480 megabits per second.”
“Welcome to Smithsonian WILD! This site is designed to showcase some of the exciting research conducted by the Smithsonian Institution and its collaborators around the world, and to highlight the incredible diversity of wildlife that exists in a range of habitats across the globe.
The use of motion-triggered ‘camera traps’ has become an incredibly useful tool for scientists to answer an enormous range of conservation and ecological questions. Researchers attach these unique cameras to posts or trees, often along forest trails, and when a camera’s sensor registers an animal’s body heat and movement, a photograph is taken.
The studies highlighted here demonstrate the range of applications of this method, and how these cameras give us a glimpse into an animal world that is rarely seen by anyone. You can search the site by following the trail of interesting animals or the lure of diverse sites around the world.”
