Comment Re:Combines all the Volume 4 fascicles (Score 1) 176

"Molecular Biology of the Cell" (colloquially: The Cell), is kind of like TAoP for cell biology. It's not short though. But combining all the TAoP Volume 4 Fascicles together, you are already at a large fraction of the amount of pages in The Cell. So I guess it's what you are looking for.

Comment Re:I wouldn't eat food right now (Score 1) 99

It is primarily about Iodine 131, that escapes from the heated fuel assemblies through tiny cracks, and is water soluble.

- Just wash the food, ~80% will wash off without much effort.
- The japanese government is tracking their food and will reject what gives off too high a dose.
- If it can wait, just don't eat fresh food from the vicinity of the reactor. Half life of Iodine-131 is 8 days. So after two weeks ~75% is gone. Still great for conserved food, or even cargo shipped.
- When you are older (> 25y or so) the impact of I-131 is much lower, since your thyroid doesn't grow (that much).

Submission + - How Well Will Linux Handle Future Multicores? (mit.edu)

eldavojohn writes: Multicore (think tens or hundreds of cores) will come at a price for current operating systems. A team at MIT found that as they approached 48 cores their operating system slowed down. After activating more and more cores in their simulation, a sort of memory leak occurred whereby data had to remain in memory as long as a core might need it in its calculations. But the good news is that in their paper (PDF), they showed that for at least several years Linux should be able to keep up with chip enhancements in the multicore realm. To handle multiple cores, Linux keeps a counter of which cores are working on the data. As a core starts to work on a piece of data, Linux increments the number. When the core is done, Linux decrements the number. As the core count approached 48, the amount of actual work decreased and Linux spent more time managing counters. But the team found that 'Slightly rewriting the Linux code so that each core kept a local count, which was only occasionally synchronized with those of the other cores, greatly improved the system's overall performance.' The researchers caution that as the number of cores skyrockets, operating systems will have to be completely redesigned to handle managing these cores and SMP. After reviewing the paper, one researcher is confident Linux will remain viable for five to eight years without need for a major redesign.

Scientists Implant Biofuel Cells Into Rats 164

RedmondChris writes "A team of scientists from Joseph Fourier University in France have successfully implanted biofuel cells into rats, generating 6.5 microwatts by harnessing the power of glucose. From the article: 'The device uses enzymes to harvest energy from glucose and oxygen found naturally in the body. Past attempts at using such a device in animals have failed because the enzymes have required acidic conditions or were inhibited by charged particles in the fluid surrounding cells. But Philippe Cinquin and his team from Joseph Fourier University in Grenoble, France, overcame these obstacles by confining selected enzymes inside graphite discs that were placed into dialysis bags. Glucose and oxygen flowed into the device, but enzymes stayed in place and catalyzed the oxidation of glucose to generate electrical energy.'"

Researchers Restore Youthful Memory In Aging Mice 145

An anonymous reader writes "German neuroscientists made a breakthrough in 'age-related cognitive decline', a common condition that often begins in one's late 40s (especially declarative memory — the ability to recall facts and experiences). Their new study identifies a genetic 'switch' for the cluster of learning and memory genes that cause memory impairment in aging mice. By injecting an enzyme, the team 'flipped' the switch to its on position for older mice, giving them the memory and learning performance they'd enjoyed when they were young. Now the team ultimately hopes to recover seemingly lost long-term memory in human patients." The video, which explains the gene flipping mechanism, is worth a watch (2:18).

So you say any explanation based on reality will not cha(lle)nge your worldview? That is fine when either reality does not matter to you (true for a lot of people), or when there is something outside of reality that changes reality without measurably changing it (either absurd, or irrelevant due to its very small influence).
