Break out the poison, boys

A panel of scientists has determined that poison is the best way to rid a Maryland pond of the carnivorous northern snakehead. The fish, a native of China, was introduced into the pond by a pet owner who tired of caring for the animals. Only problem is, the snakeheads are eating everything in sight, devastating the pond’s ecosystem. Worse, the insatiable critters can last three days out of water, often traveling short distances across land on their fins. And the Little Patuxent River is about 75 yards away. According to the Associated Press, “The panel considered several ways to get rid of the snakeheads, including removing them through trapping, netting and electroshock stunning. But those options would not ensure that every last fish was killed. The group also considered draining and filtering the pond, but that posed logistical difficulties.”

Looks like some kinda smart rodent

A single gene change that boosts the amount of a certain protein in early brain cells causes mice to develop abnormally large brains, Reuters Health reports. Normal mice have smooth, flat brains. But tinker with the gene in question and suddenly the little furballs develop brains so big they fold in on themselves, forming the wrinkles, ridges and crevices found also in the human brain. Study author Dr. Anjen Chenn of Brigham and Women’s Hospital and Harvard University in Boston said the finding might help researchers understand how humans came to develop brains so much bigger than those of other mammals. Whether or not more size means more smarts is uncertain, Chenn said. “It is quite an interesting question … and that’s something we want to look at in the future.”

Hydrogen Fuel Cell Cars Revisited

It’s hard to imagine that in what may be Big Oil’s political-clout highwater mark, anyone is talking about alternative fuel cars. But Wired does a
marathon out-take in this month’s issue, delving deep behind the Oil Curtain in a mission to GM’s Detroit headquarters. The magazine takes yet another look at the possibility that hydrogen fuel cell cars will appear in our lifetime. Wired even has the humility to point out where its previously breathless boosterism may have been a wee bit premature.

Urban legends

Boy explodes from eating Pop Rocks with Coca-Cola. Girl summons vengeful spirit by chanting “Bloody Mary” while staring into mirror. Richard Gere checks into hospital, furry friend in tow. And once again, Apple plans x86-platform Macs. As posted on MacOSRumors, “Apple may be on the way to moving over to an x86-based platform, probably the AMD Athlon family of processors.”

Historically, this techno-legend was wishful thinking on the part of cultish Apple devotees in hopes that the Mac would rise up from its Amelio-era deathbed and strike a fatal blow to the Wintel camp. Today, there are several reasons why this rumor is feasible at this time in Apple’s history: Apple’s UNIX-based MacOS X seems an easy port to CISC-based processors; The Apple/Microsoft arranged union is soon to come to a close; rumors of Motorola’s processor shortages; and so on.

“Although Motorola sources have repeatedly stated that they do not believe Apple will be implementing Moto’s G5 family of processors as it is currently known — G4 processors “have legs,” according to those sources, and will power Apple computers for at least another year, they say — we do not believe that this means that Apple will not employ PowerPC processors significantly more advanced than the current crop. It may mean that Apple does not believe that the current G5 designs are suitable in terms of clock speeds, price, or reliable supply availability. In fact, this rumor that Apple isn’t going to implement the G5 may not be accurate at all.”

Consider that CISC-based processors are larger, consume far more power and run much hotter than RISC processors, which would not fare well in many of Apple’s newer, more compact machines that do not include processor-cooling fans. Additionally, Apple touts its PowerPC G4 with Velocity Engine processor“the chip that put supercomputing power on the desktop?can perform four (in some cases eight) 32-bit floating-point calculations in a single cycle ? two to four times faster than processors found in PCs.”

Coming soon: The Big Apple

About six months after it began selling the revamped iMac, Apple will release a new version of the all-in-one PC sporting a 17-inch LCD monitor, CNET’s News.com reports. Apple hopes the new machine will spur consumer interest at a time when the entire PC industry is experiencing seriously sluggish sales. “The back-to-school market, which usually helps the September quarter, has not materialized to a great degree the past two years and may disappoint this year once again,” wrote Merrill Lynch analyst Steven Fortuna in a recent report. Apple is mum on the machine, declining to acknowledge it, let alone what it will cost. But one analyst quoted by CNET says it can’t be dramatically more than current iMacs, or buyers will stay away. “When the price is right, consumers are saying, ‘For a $600 or $700 difference, I’m not going to move, but for $200 it’s worth stepping up.'”

Loss of a troubled leader

Gene Kan, peer-to-peer file-sharing programmer extraordinaire, took his own life June 29, and Wired.com has a fine tribute to the troubled but brilliant 25-year-old. Kan’s professional life revolved around developing ways for people to swap information easily and quickly. As Wired notes, Kan was among the first programmers to create an open-source version of the file-sharing application Gnutella, which lets users search for and transfer files from computer to computer. “His ability to translate complicated technology into easily understandable terms quickly led to his becoming the unofficial spokesman for Gnutella in particular, and for file-sharing applications in general,” the new site says. “Gene was one of the first people to make hay with the idea that peer-to-peer file sharing wasn’t just about music, but about a powerful approach to problems in computer networking,” adds Tim O’Reilly, of O’Reilly Publishing. “It was Gnutella and Freenet, more than Napster, that got the attention of the technical elite and made us think more deeply about the way the Internet was evolving.” Kan’s death was not entirely unexpected, Wired reports. Friends had hoped Kan was winning his hard-fought battle against depression. “We did all the things you’re supposed to do,” said Cody Oliver, Gene’s business partner in peer-to-peer search technology gonesilent.com. “We got him on Prozac; we connected him to the suicide hotlines. He promised he wouldn’t do anything drastic. But now he’s gone. It’s a really rough time.”

Cocaine Inc.’s IT infrastructure

Business 2.0 has a compelling read in its July issue. “The Technology Secrets of Cocaine Inc.” looks at the IT infrastructure the Cali cartel has built to help manage its vast cocaine smuggling and sales empire. Particularly chilling is the organization’s use of data mining software to sift through phone records of its own operatives and the entire Cali phone exchange to see if any members were actually snitching to the authorities on the side. “They could correlate phone numbers, personalities, locations — any way you want to cut it,” said a former director of a law enforcement agency. “[Cali cocaine cartel leader Jos?] Santacruz could see if any of his lieutenants were spilling the beans.” At the heart of the system was a $1 million IBM AS400 mainframe. Observed one high-level DEA official: “It is very reasonable to assume that people were killed as a result of this capability. Potential sources of information were compromised by the system.”

The soul of a new server

Intel this week launches the Itanium 2 server processor. The company is betting big that it can convince companies which build servers to use the new chip as ubiquitously as PC makers now employ its lower-end CPUs. But the Wall Street Journal (subscription required) reports Intel has its work cut out. By Intel’s own admission, most corporate clients are already plenty happy with the oomph their existing 32-bit processors provide. And for folks that need supercomputer-level power, clustering many weaker, but far cheaper chips may provide an appealing cost-benefit ratio. Yes, there is that segment — which in revenue terms is substantial — willing to pay a premium for 64-bit processors. But in that arena Intel will compete with entrenched products from IBM, Hewlett-Packard and Sun. Finally, if and when all those dragons are slain, pokey old Advanced Micro Devices is coming round the bend with a new line of “Hammer” chips that feature both 32- and 64-bit capability. Five years from now it’ll be a kick to read a “The Soul of a New Machine“-style chronicle of how Intel handles the coming slugfest.

Hey pal, here’s a billion-five

Hand it to eBay CEO Meg Whitman: She knows a bargain when she sees it. The online auction giant said Monday it would buy PayPal for about $1.5 billion. That’s a fair enough price by any reckoning for the Internet’s most popular electronic payment service. But when the teeming masses of eBay bidders and sellers get thrown into the mix, PayPal truly becomes a bargain. Indeed, with the right marketing it could one day join the likes of Visa and MasterCard among the heavy hitters of consumer payments. It was just as smart for PayPal’s board to see recognize which way the wind’s blowing. As Reuters notes, the company already derives about 60 percent of its business from eBay.

Sh*t a brick

Taiwanese researchers say they’ve crafted a win-win situation in the discovery that sewage sludge can be used to bulk up construction bricks. The bio-bricks contain up to 30 percent sludge, which can come from either industrial slurry or the, er, human waste stream. Because the bricks are kiln-fired at 900C, all bacteria and viruses are destroyed. Plus the process seals in any heavy metals that might be present. Best of all, the researchers say, the bricks don’t smell at all. The team behind the discovery admits that people might need some convincing to live in such intimate contact with their past meals, noting that legal approval and public acceptance remain to be sought.

More confusion in cell phone, tumor flap

Science Blog reported earlier this week on a study suggesting a connection between use of an early cell phone standard and brain tumors. A separate study announced today says that no link has been found between radio emissions from mobile phones and the growth of tumors in mice. The Australian study contradicts yet another, earlier investigation that did find a connection. No word on what sort of calling plan the recent mice were allowed in the three year experiment.
