Comment Re:World Police? (Score 2) 131

We have picked up thousands of terrorists from Pakistan, and placed them in Guantanamo bay. What is your point?

A terrorist does not care who is being killed. I would love to see entire world coming together against them as a single unit, and detain them/punish them under some new international law (making sure nationality, original place of crime etc do not become obstacles.). Otherwise we will be spending time debating norms and they will emerge as winner.

My personal experience is, activities in the morning are more effective for weight loss. I used to walk ~4km in the evening for more than a year, but did not result in weight loss. But when switched to morning walk, I could see results in couple of months.

Probably it has something to do with glucose/sugar levels, which is lowest in the morning. Probably, the apps do not consider some such facts.

Submission + - SPAM: Scientists Uncover What Happens After A Black Hole Eats A Star

William Robinson writes: Using "light echoes" technique, researchers at NASA and University of Science and Technology of China have tried to understand what happens to a star after it is swallowed by a black hole. The "light echo" relies on time difference between flares from black holes eating stars, which contains high-energy radiation including ultraviolet and X-ray light, and infrared radiation from surviving dust around black hole. The surviving dust is heated by a flare and gives off infrared radiation, which gives clues about tidal disruption flares and the nature of the dust itself. A video presentation of the same.

Submission + - China Tests Quantum Radar That Detects Stealth Aircrafts (defenseworld.net)

William Robinson writes: According to some reports, China has tested its first single photon detection technology quantum radar which could detect objects, including stealth aircraft, within the range of 100 kilometres, somewhere is mid August. The radar uses quantum entanglement photons, which means it has better detection capabilities than conventional systems. This means it can more easily track modern aircraft that use stealth technology or baffle enemy radar. The report also suggests that "The system was able to detect a target at a range of 100 kms in a real-world environment".

Submission + - India Test Fires First Scramjet Engine (thehindu.com)

William Robinson writes: India test fired Advanced Technology Vehicle (ATV), a research rocket with a solid booster carrying advanced scramjet engines, which is Air Breathing Propulsion System that uses hydrogen as fuel and oxygen from the atmosphere air as the oxidiser. Since 70 per cent of the propellant mass is oxidiser, using oxidiser directly from air makes flights significantly cheaper. Also air breathing technique makes is less prone to failure because it uses less moving parts. India is fourth country to test this technology after US, Russia and EU.

Submission + - Accessing Torrent Site Will Invite Imprisonment In India (indiatimes.com)

William Robinson writes: According to recent reports, a visit a torrent website from within India , you might be committing a crime, one that earns a Rs 3 lakh fine (approx US$ 4400 ) and 3 years in prison.

Submission + - NASA TV to Air Spacewalk Live on August 19 (spacecoastdaily.com)

William Robinson writes: NASA Television will be bringing to viewers around the world live coverage Friday, Aug. 19, as two NASA astronauts install a new gateway for American commercial crew spacecraft at the International Space Station. Walking in space alone poses a threat to the astronauts performing their duty, but the new mission of installing a dock into the ISS adds to the level of difficulties that astronauts will need to survive in order to perform their duty. Coverage will begin at 6:30 a.m. EDT Aug. 19, on NASA TV and the agency’s website, with the spacewalk scheduled to begin at 8:05 a.m. Leading up to the spacewalk, NASA TV will air a briefing from the agency’s Johnson Space Center in Houston at 2 p.m. Monday, Aug. 15, during which station and commercial crew experts will discuss the process and significance of installing and connecting the first of two international docking adapters (IDAs) that will be used for the future arrivals of Boeing and SpaceX commercial crew spacecraft. Not an event to miss.

Submission + - SPAM: NASA Releases Video Of Plasma Rain On Sun's Surface

William Robinson writes: NASA has released another breathtaking video of plasma rain on the solar surface. The mid-level solar flare was captured using Interface Region Imaging Spectrograph, or IRIS. As the video continues, solar material cascades down to the solar surface in great loops, a flare-driven event called post-flare loops or coronal rain. This material is plasma, a gas in which positively and negatively charged particles have separated, forming a superhot mix that follows paths guided by complex magnetic forces in the sun’s atmosphere.
