3D-printed pizza – a quick and easy meal for astronuats?

By
Snacking on a freshly-made pizza in outer space just got a whole lot closer thanks to Anjan Contractor's 3D pizza printer. Contractor, who won NASA's US$125,000 grant last year to create a 3D printer that could print food for astronauts on missions, has come out with a functional prototype.
The prototype prints the blocky pizza out in layers, as demonstrated in the video at the bottom of the page. While it's a tad messy, the end product, when cooked, looks fairly appetizing. Contractor plans to equip the 3D printer with food cartridges that last for 30 years.
Such a long shelf life is pretty much a necessity, since long-distance space missions could take several years. To make the pizza ingredients last, Contractor is investigating ways to remove all the moisture from them and reduce the proteins, carbs and nutrients into a powder form.
Contractor says that it only took 70 seconds to cook the pizza once it was printed out, in a comment on his Youtube page. If NASA implements the technology, astronauts will be able to get 3D-printed fast food in space, which should be a comfort, instead of having to rely solely on freeze-dried and canned foods.

Nine government sites hit by cyber attacks: NIC

By
The National Informatics Center (NIC) has revealed that as many as nine government websites were defaced by recent cyber attacks. The center further said that the servers, which hosts these government sites, suffer a number of hacking attempts on a daily basis. The websites www.kumbh2010haridwar.gov.in, www.ueppcb.uk.gov.in, www.gov.ua.nic.in/ujn, www.cdodoon.gov.in, www.arunachal.nic.in,www.bee-india.nic.in, www.civilsupplieskerala.gov.in, www.mpcb.gov.in and www.informatics.nic.in were  defaced , prompting authorities to  ramp up  the cyber security safeguards. In an RTI reply, the NIC, which reports to the Ministry of Communications and Information Technology, said that it was impossible for the body to accurately quantify these attacks but they are usually blocked by security controls put in place. The Ministry was asked to provide details of hacking attempts made on the governments websites in the last ten years (2001-11) along with url names of the portal...

Solar car hits U.S. in round-the-world jaunt

By
Last October, the SolarWorld GT solar-powered car set out from Darwin, Australia on a drive around the world. It has since driven 3,001 kilometers (1,865 miles) across Australia, logged 1,947 km (1,210 miles) crossing New Zealand and been shipped across the Pacific Ocean. This Friday, it will embark on the U.S. leg of its journey, as it sets out across America from the University of California, Santa Barbara.   The SolarWorld GT is the result of a collaboration between solar panel manufacturer SolarWorld, and Bochum University of Applied Sciences in Germany. The four-wheeled, two-door, two-seat car gathers solar energy through photovoltaic panels built into its roof, with its solar generator offering a peak performance of 823 watts. Custom hub motors are located in both of the front wheels. The vehicle manages an average speed of 50 km/h (31 mph), with a claimed top speed of 100 km/h (62 mph). In order to demonstrate that solar powered cars needn't be a radical...

Google and Stanford early adopters of Honda Fit EV

By
Honda's first all-electric vehicle is hitting the streets a little early. The  Honda Fit EV  debuted at the Los Angeles Auto Show in November 2011, and it's expected to be     available for lease this summer. However,  Honda announced  that Google and Stanford University got a special early delivery of the tiny EV this week.The Honda Fit EV is equipped with a 20kWh lithium ion battery, and has an EPA estimated driving range of 76 miles. Google added the EV to its  car -sharing service for employees, dubbed the G-Fleet, in    Mountain View, Calif. The search giant maintains several electric and plug-in vehicles that it uses for research and to cart Googlers around town and between buildings on campus. Stanford University also is an early adopter of the Fit EV, but will be using it primarily for research. The university's automotive research department will study the difference in psychological and physical reactions of using battery...
