Scientists recreate human blood vessels using a 3D printer.

As bizarre as it might sound, recreating blood vessels is nothing new. The real challenge has been using 3D printers to build ones that actually work. No really - it's been something of a mental block for scientists for a while, but a new technique that fuses traditional printing methods with a substance called 'bio ink' has enabled a new team to create vessels that act just
like the real thing.

The human cardiovascular system is hardly the easiest part of human biology to replicate - a system comprising of tens of thousands of miles of capillaries, arteries and veins that reach across the whole of the body. So in order to mimic the natural distribution of blood

and nutrients, a research team based at Lawrence Livermore National Laboratory in California have used bio ink (made of materials compatible with the human body) with living cells to create fully-functioning cardiovascular pathways.More staggering is the fact that these vessels also rebuild and duplicate themselves, just like they do inside the body. “It’s going to change the way we do biology,” comments Lab research engineer Monica Moya, the project’s principal investigator. “This technology can take biology from the traditional petri dish to a 3D physiologically relevant tissue patch with functional vasculature.”

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Bing Apps for Windows 8 get major updates

Late least year, Microsoft rolled out a half dozen Bing Apps for Windows 8 users, each one focused on a specific category, such as travel and sports. The apps were designed to offer “immersive vertical experiences,” and now, about six months later, a big line of updates for them is being pushed out. Users can grab the updates now by heading into the Windows Store and selecting the updates notification.

Syrian Electronic Army claims credit for CBS Twitter accounts hack

Yesterday, several of CBS ’s Twitter accounts were hacked, including its main account, and its accounts for 60 Minutes, 48 Hours, and CBS Denver. The hackers got into the account and tweeted a series of things relating to President Obama and the United States being in cahoots with Al-Qaeda . The tweets also had links that led users to malware-infested sites. While CBS was able to regain access to its accounts, it was unable to figure out who was behind the attacks, until now. The Syrian Electronic Army , the same group that hacked 3 of the BBC’s Twitter accounts, claimed
