Breaking the Squid Barrier 126

Posted by timothy from the calimari-for-the-5000 dept.
An anonymous reader writes "Dr. Steve O'Shea of Auckland, New Zealand is attempting to break the record for keeping deep sea squid alive in captivity, with the goal of being able to raise a giant squid one day. Right now, he's raising the broad squid, sepioteuthis australis, from egg masses found in seaweed. This is a lot harder than it sounds, because the squid he's studying grow rapidly and eat only live prey, making it hard for them to keep the squid from becoming prey themselves. If his research works out, you might one day be able to visit an aquarium and see giant squid."

Pluto — a Complex and Changing World 191

Posted by timothy from the can-imagine-quite-a-bit dept.
astroengine writes "After 4 years of processing the highest resolution photographs the Hubble Space Telescope could muster, we now have the highest resolution view of Pluto's surface ever produced. Most excitingly, these new observations show an active world with seasonal changes altering the dwarf planet's surface. It turns out that this far-flung world has more in common with Earth than we would have ever imagined."

Dinosaur Feather Color Discovered 219

Posted by timothy from the horsefeathers-still-a-mystery dept.
anzha writes "Do you remember being a kid and told we'd never know what colors the dinosaurs were? For at least some, that's no longer true. Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!"

Scientists To Breed the Auroch From Extinction 277

Posted by samzenpus from the back-by-popular-demand dept.
ImNotARealPerson writes "Scientists in Italy are hoping to breed back from extinction the mighty auroch, a bovine species which has been extinct since 1627. The auroch weighed 2,200 pounds (1000kg) and its shoulders stood at 6'6". The beasts once roamed most of Asia and northern Africa. The animal was depicted in cave paintings and Julius Caesar described it as being a little less in size than an elephant. A member of the Consortium for Experimental Biotechnology suggests that 99% of the auroch's DNA can be recreated from genetic material found in surviving bone material. Wikipedia mentions that researchers in Poland are working on the same problem."

Using EMP To Punch Holes In Steel 165

Posted by timothy from the you'll-need-some-big-batteries dept.
angrytuna writes "The Economist is running a story about a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, who've found a way to use an EMP device to shape and punch holes through steel. The process enjoys advantages over both lasers, which take more time to bore the hole (0.2 vs. 1.4 seconds), and by metal presses, which can leave burrs that must be removed by hand."

How Earth Avoided a Fiery Premature Death 114

Posted by kdawson from the flood-next-time dept.
Hugh Pickens writes "Space.com has a piece about changing theories of planet migration. The classic picture suggests that planets like Earth should have plummeted into the sun while they were still planetesimals, asteroid-sized building blocks that eventually collide to form full-fledged planets. 'Well, this contradicts basic observational evidence, like We. Are. Here,' says astronomer Moredecai-Mark Mac Low. Researchers investigating this discrepancy came up with a new model that explains how planets can migrate as they're forming and still avoid a fiery premature death. One problem with the classic view of planet formation and migration is that it assumes that the temperature of the protoplanetary disk around a star is constant across its whole span. It turns out that portions of the disk are opaque and so cannot cool quickly by radiating heat out to space. So in the new model, temperature differences in the space around the sun, 4.6 billion years ago, caused Earth to migrate outward as much as gravity was trying to pull it inward, and so the fledgling world found equilibrium in its current, habitable, orbit. 'We are trying to understand how planets interact with the gas disks from which they form as the disk evolves over its lifetime,' adds Mac Low. 'We show that the planetoids from which the Earth formed can survive their immersion in the gas disk without falling into the Sun.'"

Mexico Wants Payment For Aztec Images 325

Posted by samzenpus from the montezuma's-latest-revenge dept.
innocent_white_lamb writes "Starbucks brought out a line of cups with prehistoric Aztec images on them. Now the government of Mexico wants them to pay for the use of the images. Does the copyright on an image last hundreds of years?"

Ocean-Crossing Dragonflies Discovered 95

Posted by samzenpus from the incredible-journey dept.
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."

Blu-ray Capacity Increase Via Firmware 232

Posted by timothy from the best-stuff-happens-in-software dept.
LordofEntropy writes "Blu-ray.com reports that Sony and Panasonic have announced a new optical disc evaluation technology that increases capacity from 25GB to 33.4GB. The tech uses existing Blu-ray diodes and is accomplished via firmware upgrade. The article says it is not known if and when the upgrade will be adopted into the Blu-ray spec. However, given that Sony and Panasonic are behind it, 'it will likely happen later this year.'"
