Submitter Shortyadamk first accepted in writing I just started a new job where I have to visit many high school science classes and students involved in projects of 1-3 days on sustainable energy science and the environment (in order to promote regional universities. programs) I looked at a number of projects supervised available online and many of them are solar projects, my biggest problem with this is that we are in a region rural Alaska and most of the time I visit classes will be the winter (when we have very little light – and even if we did it would be too cold to play in).

Of course, we all thought about how it would be nice to have our PS3 and Xbox 360 consoles in the same enclosure. But, like many similar thoughts are going, we left there. Not content to simmer a good thought, the user Reddit
timofend accepted the challenge and has built a mega-machine gambling – he thrust the new model Slim console from Microsoft in a tower next to a PC old 80GB PS3. Looking to save money in the process, the über-gamer jumped on a liquid cooling system – but notes that when the two machines operate simultaneously, they each hover around 100 degrees Fahrenheit (38 degrees Celsius). Hey, we’re not complaining … but really, timofend, can we please see a NES / Dreamcast / PlayStation OG combo in your next masterpiece? To take a look under the hood, hit the gallery below.

Just a few days after the introduction of Android as its own OS, Baidu is now looking to expand its mobile reach the front of the hardware, with help from Dell. According to Reuters,
the Chinese search giant has joined forces with the PC manufacturer to produce a line of tablets and smartphones in China, hoping to capitalize on a market of over 900 million mobile subscribers. A Dell spokesman declined to give a launch date of the new product line, but sources familiar with the matter say they could launch in November. Instrument Details remain as opaque, but Dell seems to resurrect his tablet / handset unit, following the collapse of the Streak 5 . We have a partnership with Baidu, and you know, we have the Streak 5 tablet, so that the partnership will be in this space, the company representative said, adding that future versions imply Baidu platform mobile application, as well. Today’s announcement also comes after Dell’s Chinese sales rose 22 percent in the first quarter of this year, but it remains to be seen whether the alliance will have much effect on a market today dominated by Apple and Lenovo.

RogerRoast writes An article published in the journal Cell, molecular signals from fat cells (adipocytes) precursors under the skin are needed to stimulate hair growth in mice. Yale researchers report in the newspaper that these cells produce molecules called PDGF (platelet derived growth factor), which are required to produce hair growth. The discovery of the source of signals that trigger hair growth can lead to new treatments for baldness. The trick is to obtain precursors of adipocytes under the skin of about stem cells at the base of the hair follicles.
