Dave Knott writes "The CBC's weekly science radio show Quirks and Quarks this week features a countdown of the top ten planetary doomsday scenarios. Nine science professors and one science fiction author are asked to give (mostly) realistic hypotheses of the ways in which the planet Earth and its inhabitants can be destroyed. These possibilities for mankind's extinction include super-volcanoes, massive gamma ray bursts, and everybody's favorite, the killer asteroid. Perhaps the most terrifying prediction is the reversal of the Earth's magnetic field (combined with untimely solar activity), a periodic event which is currently 1/4 million years overdue."

The New Yorker is running a piece by Atul Gawande that starts by describing the everyday miracles that can be achieved in a modern medical intensive care unit, and ends by making a case for a simple and inexpensive way to save 28,000 lives per year in US ICUs, at a one-time cost of a few million dollars. This medical miracle is the checklist. Gawande details how modern medicine has spiraled into complexity beyond any person's ability to track — and nowhere more so than in the ICU. "A decade ago, Israeli scientists published a study in which engineers observed patient care in ICUs for twenty-four-hour stretches. They found that the average patient required a hundred and seventy-eight individual actions per day, ranging from administering a drug to suctioning the lungs, and every one of them posed risks. Remarkably, the nurses and doctors were observed to make an error in just one per cent of these actions — but that still amounted to an average of two errors a day with every patient. Intensive care succeeds only when we hold the odds of doing harm low enough for the odds of doing good to prevail. This is hard." The article goes on to profile a doctor named Peter Pronovost, who has extensively studied the ability of the simplest of complexity tamers — the checklist — to save lives in the ICU setting. Pronovost oversaw the introduction of checklists in the ICUs in hospitals across Michigan, and the result was a thousand lives saved in a year. That would translate to 28,000 per year if scaled nationwide, and Pronovost estimates the cost of doing that at $3 million.

mhm was one of many readers to note that the Linux 2.6 kernel has been ported to the iPhone. "Planetbeing, one of the iPhone devteam members, has been working on porting Linux to the iPhone (along with a custom bootloader called OpeniBoot). Today they managed to boot the kernel! Video showing the boot process has been posted. Instructions and binaries are available on the project blog."

nandemoari writes "According to a recent advertisement airing on American TV, Apple's new Macbooks (well-received by most technology critics) are 'the world's greenest family of notebooks.' It seems an indication that the Cupertino-based company is increasingly aware of a consumer base that demands green electronics. However, Greenpeace is less than enthused with Apple's overall green performance. In their report (PDF), the environmentalists argue that Apple 'needs to commit to phasing out additional substances with timelines, improve its policy on chemicals and its reporting on chemicals management.'" Ars Technica points out that Greenpeace's research isn't quite up-to-snuff, and it's also worth noting that Greenpeace admitted to targeting Apple for the publicity in the past.

Dr. Eggman writes "CVG has a recent article on Valve's future plans for episodic gaming. After the third episode of Half-Life 2 is out, Valve plans to sit down with the community and figure out what is working and what's not. Gabe Newell also wants to spend time with Telltale Games and Blizzard, both developers of episodic and episodic-like game content. It it worth it to try to release content on an episodic basis? 'We just want to sit down with three examples in front of us and talk it over with gamers to find out what they would like us to do next.'"

Virgil Tibbs writes "With the Launch of the BBC's iPlayer imminent, the BBC trust has agreed to hear the Open Source Consortium's concerns regarding the BBC iPlayer's tie in with Microsoft's software. The move by the BBC to use Windows Media DRM & their apparent lack of commitment towards other platforms has caused outrage in many circles and prompted several online petitions."
