ISRO to launch regional navigation satellite system IRNSS 1C on October 10

New Delhi: ISRO will launch the third of seven series of satellites to put in place India's own navigation system on par with US' Global Positioning System (GPS) from the spaceport of Sriharikota on October 10. The launch has been scheduled at 1.56 AM on October 10, ISRO said today.<h2>ISRO to launch regional navigation satellite system IRNSS 1C on October 10</h2><img alt="" src="http://static.dnaindia.com/sites/default/files/2014/10/03/272129-isro.jpg" width="600" />The IRNSS 1C satellite would be launched on the 28th flight of India's PSLV-C26 from the Satish Dhawan Space Centre at Sriharikota, some 100 km from here.As part of its aspirations to build a regional navigational system equivalent to Global Positioning System of the US, ISRO plans to send seven satellites to put in place the Indian Regional Navigational Satellite System (IRNSS). The first two satellites in the series, IRNSS 1A and IRNSS 1B were launched from Sriharikota on July 1 2013 and April 4 this year respectively.ISRO needs to launch at least four of the seven satellites to start operations of the IRNSS, ISRO officials said.Being developed by India, IRNSS is designed to provide accurate position information service to users in the country as well as the region extending upto 1,500 km from its boundary, which is its primary service area.IRNSS' applications include terrestrial and marine navigation, disaster management, vehicle tracking and fleet management.IRNSS is similar to US' Global Positioning System, Russia's Glonass and Europe's Galileo. China and Japan also have similar systems, 'Beidou' and 'Quasi Zenith', ISRO officials said.

Scientists harvest hydrogen fuel from Sun

London, Sep 26 - In the race to optimize solar energy's performance, scientists have used earth-abundant materials to harvest hydrogen fuel from the sun's energy.<h2>Scientists harvest hydrogen fuel from Sun</h2><img alt="" src="http://www.howitworksdaily.com/wp-content/uploads/2013/02/sun.jpg" width="600" />Their device converts into hydrogen 12.3 percent of the energy diffused by the sun on perovskite absorbers - a compound that can be obtained in the laboratory from materials such as those used in conventional car batteries.This eliminates the need for rare-earth metals in the production of usable hydrogen fuel.Both the perovskite used in the cells and the nickel and iron catalysts making up the electrodes require resources that are abundant on Earth and that are also cheap, explained Jingshan Luo, post-doctoral student in the team of lead researcher Michael Gratzel at the Swiss Federal Institute of Technology in Lausanne.Our electrodes work just as well as the expensive platinum-based models customarily used, Gratzel said.The conversion of solar energy into hydrogen makes its storage possible which addresses one of the biggest disadvantages faced by renewable electricity.Once you have hydrogen, you store it in a bottle and you can do with it whatever you want to, whenever you want, Gratzel noted.Such a gas can indeed be burned - in a boiler or engine - releasing only water vapour.It can also pass into a fuel cell to generate electricity on demand.And the 12.3 percent conversion efficiency achieved will soon get even higher, Gratzel added.The paper appeared in the journal Science.

US Woman undergoes surgery to add a third breast

Washington: People do strange things for their 15 minutes of fame.A US massage therapist who wanted a become a reality TV star has undergone surgery to add a third breast to her chest.<h2>US Woman undergoes surgery to add a third breast</h2><img alt="" src="http://media2.intoday.in/indiatoday/images/stories//2014September/jasmine1_mos_092214121817.jpg" width="600" />Jasmine Tridevil, who hails from Florida, spent $20,000 on the surgery a few months ago says she had to call up 50 doctors before she found a doctor who would do the surgery.Jasmine Tridevil, who underwent surgery to add a third breast to her chest.<img alt="" src="http://media2.intoday.in/indiatoday/images/stories//2014September/jasmine_story_650_092214121817.jpg" width="600" />Speaking to Real Radio 104.1, Jasmine said, "It was really hard finding someone that would do it too because they're breaking the code of ethics."Jasmine's third breast was constructed in the middle of her chest with a silicone implant and skin tissue from her abdomen.However, since an artificial areola couldn't be created, Jasmine got it tattoed on.She says, apart from her desire to be a reality TV star, she wanted the third breast so that he could become unattractive to men.Understandably enough, Jasmine's parent's weren't very receptive to the idea of her third breast. Her mother and sister aren't talking to her and her dad is "kind of ashamed" of her but has accepted it.But beyond the simple reason of being a reality TV star, Jasmine says, she wanted it to make herself unattractive to men because she doesn't want to date anymore.For all those interested, you can see more of Jasmine's assets on her YouTube channel as well as her Facebook page.

Stephen Hawking warns 'God particle' has potential to 'end world'

Stephen Hawking has recently warned that the God Particle or Higgs boson has the potential to obliterate the universe.Stephen Hawking has recently warned that the God Particle or Higgs boson has the potential to obliterate the universe. The 72-year-old cosmologist said Higgs boson could become unstable at very high energy levels, which would lead to a "catastrophic vacuum decay" causing space and time to collapse and that there would not be any warning to the danger, the Daily Express reported.<h2>Stephen Hawking warns 'God particle' has potential to 'end world'</h2><img alt="" src="http://static.dnaindia.com/sites/default/files/2014/09/08/265824-stephenhawking.jpg" width="600" />The 72-year-old cosmologist said Higgs boson could become unstable at very high energy levels, which would lead to a "catastrophic vacuum decay" causing space and time to collapse and that there would not be any warning to the danger, the Daily Express reported.Speaking in the preface to a new book called Starmus, the Cambridge-educated scientist said that the Higgs potential has the worrisome feature that it might become megastable at energies above 100bn giga-electron-volts (GeV).However, Mr Hawking did also mention that the likelihood of such a disaster was unlikely to happen in the near future, but the danger of the Higgs becoming destabilised at high energy was too great to be ignored.The Higgs boson was discovered in 2012 by scientists at CERN, who operate the world's largest particle physics laboratory.
