An anonymous reader writes “A team of US researchers has asked the following question in the new field of systems biology: ‘Do we understand how a cell produces electricity well enough to design one, and to optimize that design?’ They believe it should be possible to build artificial cells replicating the electrical behavior of electric eel cells. In fact, such artificial cells could deliver better performance — as much as 40% more energy than real eel cells, a computer model suggests. They could be used to power medical implants and other small devices.”

Khemisty writes “Formation of an ocean is a rare event, one no scientist has ever witnessed. Yet this geophysical nativity is unfolding today in one of the hottest and most inhospitable corners of the globe. Africa is splitting apart at the seams. From the southern tip of the Red Sea southward through Eritrea, Ethiopia, Kenya, Tanzania, and Mozambique, the continent is coming unstitched along a zone called the East African Rift.” This stretching of the earth’s crust has been going on for 20 million years, and within another 10 million the Red Sea will have broken through to create a new sea.

An anonymous reader alerts us to a two-week-old story that hasn’t gotten much traction in the press to date. A Japanese newspaper and the AP report that China plans to demand source code from hardware manufacturers, and ban the sale of products from companies that don’t comply. China is calling this an “obligatory accreditation system for IT security products.” The plan is to go into effect next May, according to sources. “Products expected to be subject to the system are those equipped with secret coding, such as [a] contactless smart card system developed by Sony Corp., digital copiers, and computer servers. The Chinese government said it needs the source code to prevent computer viruses taking advantage of software vulnerabilities and to shut out hackers. However, this explanation is unlikely to satisfy concerns that disclosed information might be handed from the Chinese government to Chinese companies. There also are fears that Chinese intelligence services could exploit such confidential information by making it easier to break codes used in… digital devices.”

Science News reports on a paper to be published in Physical Review Letters in which an international team of researchers describes their computer simulation of the most violent collision imaginable: two black holes colliding head-on at nearly light-speed. Even in this extreme scenario, Roger Penrose’s weak cosmic censorship hypothesis seems to hold — the resulting black hole (after the gravitational waves have died down) retains its event horizon. “Mathematically, ‘naked’ singularities, or those without event horizons, can exist, but physicists wouldn’t know what to make of them. All known mechanisms for the formation of singularities also create an event horizon, and Penrose conjectured that there must be some physical principle — a ‘cosmic censor’ — that forbids singularity nakedness…”

Wired is running a story about a case the Supreme Court will be hearing on Tuesday that relates to searches based on erroneous information in government databases. In the case of Herring vs. US 07-513, the defendant was followed and pulled over based on a records indicating he had a warrant out for his arrest. Upon further review, the local county clerk found the records were in error, and the warrant notification should have been removed months prior. Unfortunately for Herring, he had already been arrested and his car searched. Police found a small amount of drugs and a firearm, for which Herring was subsequently prosecuted. Several friend-of-the-court briefs have been filed to argue this case, some calling for “an accuracy obligation on law enforcement agents [PDF] who rely on criminal justice information systems,” and others defending such searches as good-faith exceptions [PDF].

UniverseToday has an interesting look at geomagnetic reversal, the process in which the Earth’s magnetic poles trade places. The article cites known trends and recent studies to debunk doomsday myths and unsubstantiated claims about the process. One such study is attempting to model the earth’s core with a 26-ton ball of molten metal. Another recently found evidence that the Earth has a second, weaker magnetic field. “We do know that this magnetic pole flip-flop has occurred many times in the last few million years; the last occurred 780,000 years ago according to ferromagnetic sediment. A few scaremongering articles have said geomagnetic reversal occurs with ‘clockwork regularity’ — this is simply not true.”

On Friday someone posted a false rumor that Steve Jobs had suffered a heart attack on CNN’s unverified citizen journalism site, iReport. Apple’s stock price went vertical, losing 9% before Apple stepped in and denied the rumor; the stock then recovered most of its loss. The SEC is investigating. PCWorld looks at the hit taken by citizen journalism as a result of this incident. “[The] increasingly blurred line between journalism and rumor is a serious concern for Al Tompkins, the broadcast/online group leader at The Poynter Institute — a specialized school for journalists of all media forms. ‘How could you possibly allow just anybody to post just anything under your [CNN] label unless you have blazing billboards that say, “None of this has been verified, we’ve not looked at any of this, we have no idea if this is true?”‘ he asks.”

darkeye writes “I’m facing a difficult dilemma and looking for opinions. I’ve been contributing heavily to an open source project, making considerable changes to code organization and quality, but the work is unfinished at the moment. Now, a company is approaching me to continue my changes. They want to keep the improvements to themselves, which is possible since the project is published under the BSD license. That’s fair, as they have all the rights to the work they pay for in full. However, they also want me to sign a non-competition clause, which would bar me from ever working on and publishing results for the original open source project itself, even if done separately, in my free time. How would you approach such a decision? On one side, they’d provide resources to work on an interesting project. On the other, it would make me an outcast in the project’s community. Moreover, they would take ownership of not just what they paid for, but also my changes leading up to this moment, and I wouldn’t be able to continue on my original codebase in an open source manner if I sign their contract.”

Ian Lamont recently asked Google if they planned to extend their transcription of books and other printed media to include public records, many of which were handwritten before word processors became ubiquitous. Google wouldn’t talk about any potential plans, but Lamont found out a bit more about the limits of optical character recognition in the process: “Even though some CAPTCHA schemes have been cracked in the past year, a far more difficult challenge lies in using software to recognize handwritten text. Optical character recognition has been used for years to convert printed documents into text data, but the enormous variation in handwriting styles has thwarted large-scale OCR imports of handwritten public documents and historical records. Ancestry.com took a surprising approach to digitizing and converting all publicly released US census records from 1790 to 1930: It contracted the job to Chinese firms whose staff manually transcribed the names and other information. The Chinese staff are specially trained to read the cursive and other handwriting styles from digitized paper records and microfilm. The task is ongoing with other handwritten records, at a cost of approximately $10 million per year, the company’s CEO says.”
