Velcroman1 writes with this snippet from Fox News: "Using lead weights and depth sounders, scientists have made surprisingly accurate estimates of the ocean's depths in the past. Now, with satellites and radar, researchers have pinned down a more accurate answer to that age-old query: How deep is the ocean? And how big? As long ago as 1888, John Murray dangled lead weights from a rope off a ship to calculate the ocean's volume — the product of area and mean ocean depth. Using satellite data, researchers from the Woods Hole Oceanographic Institute set out to more accurately answer that question — and found out that it's 320 million cubic miles. And despite miles-deep abysses like the Mariana Trench, the ocean's mean depth is just 2.29 miles, thanks to the varied and bumpy ocean floor."

TheOtherChimeraTwin notes that the shuttle Discovery will land at Kennedy Space Center on Monday morning at 8:48 EDT. The craft will make a rare "descending node" overflight of the continental US en route to landing in Florida. Here are maps of the shuttle's path if is lands on orbit 222 as planned, or on the next orbit. Spaceweather.com says: "...it takes the shuttle about 35 minutes to traverse the path shown... Observers in the northwestern USA will see the shuttle shortly after 5 am PDT blazing like a meteoric fireball through the dawn sky. As Discovery makes its way east, it will enter daylight and fade into the bright blue background. If you can't see the shuttle, however, you might be able to hear it. The shuttle produces a sonic double-boom that reaches the ground about a minute and a half after passing overhead."

astroengine writes "A new radio telescope is under construction, consisting of 44 stations (each consisting of several antennae) spread across Europe. The pan-European Low Frequency Array is half built and already returning unprecedented observations of cosmic radio sources. The best thing is, when it's complete, SETI will be able to use the array to seek out transmitting extraterrestrial civilizations in these untapped low radio frequencies."

Gmer writes "Eming.com reports that OpenTTD, the open source clone of the Microprose game Transport Tycoon Deluxe, has reached a milestone. OpenTTD 1.0.0 has been released 6 years after work started on the first version, with the help of hundreds of contributors and thousands of testers/players. Over 30 language translations are considered complete, and OpenTTD is available for *BSD, Linux, Solaris and Windows. OpenTTD is a business simulation game in which the player is in control of a transport company and can compete against rival companies to make as much profit as possible by transporting passengers and various goods by road, rail, sea or air."

thomst writes "Charles Q. Choi of LiveScience reports that a farmer in southern Henan Province in China has dug up the first known ant-eating dinosaur, a half-meter-long theropod (the dinosaur family to which T. Rex belongs), whose fossilized remains were described as 'fairly intact'. The 83- to 89-million-year-old pygmy dinosaur has been named named Xixianykus zhangi by Xig Xu, De-you Wang, Corwin Sullivan, David Hone, Feng-lu Han, Rong-hao Yan, and Fu-ming Du, whose paper on the critter, A basal parvicursorine (Theropoda: Alvarezsauridae) from the Upper Cretaceous of China, was published in the March 29 issue of Zootaxa (the abstract is available in PDF format for free, the full article is paywall-protected.)"

bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."
