Ultrawideband Signal Passes Data Through Walls 139

Posted by Zonk from the wireless-fight-out dept.
writertype writes "You may already be familiar with ultrawideband; UWB technology has been specifically talked about and designed to replace wired USB connections for over a year. Due to its high bandwidth, it's also been considered as an A/V cable replacement. The problem is that UWB radio performance degrades precipitously, effectively confining it to a single room. Until now, that is. Startup TZero says its UWB implementation provides high throughput through walls. Will this be an effective competitor to 802.11n?"

3D Human Cells Grown 138

SR_melb writes writes to tell us that Melbourn researchers have, for the first time, managed to grow three dimensional human cells. This bypasses previous achievements of only being able to create two-dimensional constructions like skin. From the article: "Professor Wayne Morrison, from Melbourne's Bernard O'Brien Institute of Microsurgery has led the breakthrough. He says it's a world first and predicts the discovery will ultimately lead to the creation of human organs, including parts of the heart, by using the patients' own stem cells. Such a scenario, says Professor Morrison, would reduce the problem of immune rejection which is often associated with organ transplants."

Reverse Multithreading CPUs 263

Posted by ScuttleMonkey from the quick-geordi-reverse-the-polarity dept.
microbee writes "The register is reporting that AMD is researching a new CPU technology called 'reverse multithreading', which essentially does the opposite of hyperthreading in that it presents multiple cores to the OS as a single-core processor." From the article: "The technology is aimed at the next architecture after K8, according to a purported company mole cited by French-language site x86 Secret. It's well known that two CPUs - whether two separate processors or two cores on the same die - don't generate, clock for clock, double the performance of a single CPU. However, by making the CPU once again appear as a single logical processor, AMD is claimed to believe it may be able to double the single-chip performance with a two-core chip or provide quadruple the performance with a quad-core processor."
