XFX 1000W Pro Series 80 Plus Platinum


We've recently tested the first 80 Plus Platinum PSUs to hit our labs, courtesy of Seasonic and Enermax. Both were good if expensive PSUs, and next up on the test bench is a Platinum series that's sold by a brand without their own PSU factory: XFX. They sent us their newest product, the Pro Series 80 Plus Platinum Black Edition, which sets its sights on the high-end of the market. XFX has created an interesting casing with some unusual elements, but we need to find out how good this model actually is.

While efficiency is all the marketing rage in the world of PSUs, we should keep in mind that many manufacturers are trying to reach 80 Plus Platinum levels using some "tricks". As we noted in our Seasonic article, there are various routes to higher efficiency, like removing resistors that may fill other roles. Shunt resistors for example transform some of the power into power loss when current flows through it, since there is a voltage drop. That's actually their job as they measure and prevent overcurrent in an indirect way. On the following pages we will show how XFX reached the requirements for 80 Plus Platinum (90%/92%/89% efficiency at 20%/50%/100% load), and we'll also discuss the ODM and how well the XFX model fares in an increasingly crowded market.

Japan Creates Earthquake-Proof Levitating House System


An anonymous reader writes "Japanese company Air Danshin Systems Inc. has developed an innovative system that levitates houses in the in the event of an earthquake to protect them from structural damage. When an earthquake hits, a sensor responds within one second by activating a compressor, which forces an incredible amount of air under the home, pushing the structure up and apart from its foundation. The air pressure can keep the home levitating up to 3cm from the shaking foundation below. In the wake of last year's Fukushima disaster the company is set to install the levitation system in 88 houses across Japan."

Withings Baby Monitor makes its official, expensive US debut

Withings Baby Monitor
The Withings Baby Monitor has already been available in the UK for sometime now and recently made a splash over at the FCC. Now the iOS accessory is finally for sale here in the good ol' US-of-A, for the rather staggering price of $299. That's right, this sensor-packed web cam probably costs more than your handset. Then again, that $20 set of audio-only monitors you picked up at Walmart can't keep you abreast of the temperature and humidity in your child's sleeping quarters or let you watch your newborn sleep with the aid of a night vision mode. You can get the associated WithBaby app for free in the iTunes App Store now. The only question is, whether or not you love your baby enough to spend $300 on an iPhone accessory. We won't judge you either way. Check out the PR after the break.

Stem Cell Firm May Have Administered Unproven Treatments


ananyo writes "With Texas pouring millions of dollars into developing adult stem-cell treatments, doctors there are already injecting paying customers with unproven preparations, supplied by an ambitious new company. Celltex Therapeutics 'multiplies and banks' stem cells derived from people's abdominal fat and its facility in Sugar Land opened in December 2011 and houses the largest stem-cell bank in the United States. But Nature has uncovered evidence that the company is involved in the clinical use of the cells on US soil, which the FDA has viewed as illegal in other cases."
