Submission + - Breathing Beijing's Air is The Equivalent of Smoking Almost 40 Cigarettes a Day ->

iONiUM writes: From the economist: "Pollution is sky-high everywhere in China. Some 83% of Chinese are exposed to air that, in America, would be deemed by the Environmental Protection Agency either to be unhealthy or unhealthy for sensitive groups. Almost half the population of China experiences levels of PM2.5 that are above America’s highest threshold. That is even worse than the satellite data had suggested."

They go on to say "Berkeley Earth’s scientific director, Richard Muller, says breathing Beijing’s air is the equivalent of smoking almost 40 cigarettes a day and calculates that air pollution causes 1.6m deaths a year in China, or 17% of the total. A previous estimate, based on a study of pollution in the Huai river basin (which lies between the Yellow and Yangzi rivers), put the toll at 1.2m deaths a year—still high."

Submission + - Is Shooting 4K Video for Youtube Worth It?->

Iddo Genuth writes: Linus Sebastian (from LinusTechTips) decided to see how much of a real world difference is there between shooting 1080p and shooting 4K if your end goal is uploading your content to Youtube as well as watching video in 4K that was upscaled to 4K from 1080p.

More and more content is being shot in 4K these days, especially when there are so many inexpensive cameras with 4K capabilities on the market — but can you really tell the difference between native 4K and upscaled 1080p? the answer seems to be pretty surprising (and a bit complicated and maybe even controversial).

Even if you are not a content creator and just watch stuff on youtube — Linus' video has some interesting bottom line for you in terms of setting your Youtube quality level to the max (if your bandwidth can handle that).

What is your experience — and do you see the differences that Linus was talking about (we couldn't — but we didn't use a 4K screen...).

Submission + - Singularity 1on1: Humanity's make or break period! ->

sys64764 writes: "Skynet begins to learn at a geometric rate. It becomes self-aware at 2:14 a.m. Eastern time, August 29th. In a panic, they try to pull the plug."

Skynet won't have a hard time crushing Mankind after all, it could just take over all car... If you like what Marshall Brain does (Manna, HowStuffWorks,...) you can watch Nikola Danaylov (Singularity Weblog) pick his brain about singularity. Grab a beer, get comfortable, go fullscreen and watch Brian explain his take on humanity's make or break moment.

Submission + - Transparent Aluminum is 30 years late, but finally here. ->

Charliemopps writes: Though it's 30 years late, Transparent Aluminum, as predicted in the 1986 film Star Trek IV: The Voyage Home, may finally be here. There have been many attempts to create transparent metals in the pass few years, and some have been somewhat successful, if only for a few femtoseconds.

But now, by modifying metals like Silver and Aluminum at the subwavelength scale, researchers are developing "Meta-Materials" that causes light to interact with these metals in new and interesting ways. One of their more promising goals is to create a "perfect lens" which would allow an every day person to view things as small as a virus with the naked eye. Will this eventually lead to whale sized fish tanks as clear as glass with the strength of aluminum? Only time will tell.

Submission + - Elon Musk offers explanation for loss of Falcon 9 mission

garyisabusyguy writes: This Forbes article provides the best analysis of the loss of the last Falcon 9 mission based on information released by Elon Musk.
1. Sound triangulation led them to identify a strut holding helium tank as root cause where the falling helium tank pinched a line causing overpressure in the LOX tank.
2. The failure occurred at 2,000 pounds of force, and the struts were rated at 10,000 pounds of force. They initially dismissed this as a cause until sounds triangulation pointed back to the strut
3. Further testing of struts in stock found one that failed at 2,000 pounds of force, with further analysis identifying poor grain structure in the metal, which caused weakness
4. It will be months before the next launch while SpaceX goes over procurement and QA processes all struts and bolts, and re-assesses any "near misses" with Air Force and NASA
5. Next launch will include failure mode software, which will allow recovery of the Dragon module during loss of the launch vehicle since they determined that it could have saved the Dragon module in this lost mission

I'm still waiting for them to stick the landing,which could be a way in the future
