Just pretend to pass out and hold your breath to get that CPR.

Alls I'm saying is if I have to pick either the left or right to save my drowning butt I'll pick the left one.
If you want the super duper drone.. more power to you
i'm old school like that.

Chinese scientist develops world's most accurate 3rd-gen sequencer

GenoCare, a new class of third-generation sequencing platform, designed and made by Chinese company Direct Genomics, is capable of directly measuring DNA and RNA sequencings at the single-molecule level without amplification, an article from biochemical sciences journal BioRxiv revealed on July 13, Science and Technology Daily reported.
Chinese and American scientists used the new GenoCare single molecule sequencing platform to resequence the E. coli genome. Results show that the accuracy of the new platform reached 99.71 percent [ed -- actually, the paper showed that the GenoCare system managed "a consensus sequence of 99.71% nucleotide identity to that of the Illumina MiSeq system" -- we should account for the fact that measuring devices never have zero error, so what the paper shows is comparable performance to that of the Illumina system () ], making it the most accurate sequencing platform in the world.
He Jiankui, born in 1980s, is the leading scientist of the research and development of the automated desktop sequencer GenoCare and a professor from Southern University of Science and Technology. At present, GenoCare is the only reliable third-generation sequencing platform with strong potential for clinical applications in the world, said He.

According to He, the first-generation DNA sequencing technology completed the first human genome mapping in 2001. The mapping process took three years, and cost billions of US dollars. The second-generation sequencing technology shortened the time to less than one week and shrunk the cost to $1,000. The latest technology is able to complete the work in 24 hours for only $100.
The core technology of the GenoCare platform is single-molecule fluorescence sequencing. The GenoCare detects single-molecule fluorescence by employing total internal reflection microscopy, together with sequencing-by-synthesis chemistry. The technology has greatly improved accuracy and lowered cost.
Yu Jun, a researcher at the Beijing Institute of Genomics, pointed out that the third-generation sequencer can be applied in both research and clinical fields, and has unlimited commercial prospects.

China increases top high speed rail speeds back to 350 kph and soon 400 kph
| July 20, 2017 |
China is upgrading its high speed rail trains to new trains with a 400 kph top speed. Hundreds of trains will be upgraded to the higher top speed and more lines will be permitted to run at the higher 350 kph speed and perhaps in two years or so the trains will be permitted to run at 400 kph.
Travelers will be able to zip between the two cities in just 4 hours aboard the G1. Currently, those bullet trains crawl across the country at max speeds of only 300 kilometers per hour, making the 1,318-kilometer trip in an excruciating 4 hours and 49 minutes.

When the 400 kph top speed is permitted then the travel time from Shanghai to Beijing will drop to 3.5 hours.
China is also working on new trains that could reach top speeds of 600 kph. This would enable travel times to drop to 2.3 hours (2 hours and 20 minutes) between Shanghai and Beijing. The higher speeds will cause more travelers to switch from airplanes to high speed rail on longer and longer routes.
High speed rail provides people with more space and comfort and generally lower ticket costs.
The speed of the second-tier ‘D’ trains reduced from 250 to 200 km/h (155 to 124 mph). The speed of the remaining 350 km/h (220 mph) trains between Shanghai and Hangzhou was reduced to 300 km/h (186 mph) as of 28 August 2011.
Railway officials are currently hard at work testing and getting ready for the big speed boost which will include both China’s old-school Hexie trains, as well as its newly-developed Fuxing bullet trains, which have a top speed of 400 kilometers per hour.
New Fuxing trains last longer and consume 17% less energy than their outdated predecessors and have the 400 kph top speed. The new train is designed to be more user-friendly, with Wi-Fi and more power sockets.
Systems on the new EMU range, including traction, braking and local area networks are wholly owned by China, Zhao Hongwei, vice main engineer and researcher at the China Academy of Railway Sciences.
This solves the problem that internal layout and replacement parts on existing high-speed trains do not couple together, she said.
There are four types of in-service bullet trains in China, introduced from Japan, Germany, France and Canada, Zhao Ting, a professor at the Beijing Jiaotong University, told the Global Times.
“The China-designed trains will be reducing less system maintenance costs, since 84 percent of its products are of Chinese standards … and China will soon replace existing trains with the new ones within a couple of years,” Zhao Ting said.
According to the China Academy of Railway Sciences, the new model has a service life of over 30 years, compared with the existing ones that can operate for 20 years.
“The Fuxing trains are 4,050 millimeters high, compared with 3,700 millimeters of the Hexie. Thanks to new designs, the Fuxing’s wind resistance is 7.5 to 12.3 percent less than the previous generation, and noise in the carriage is noticeably reduced,” said Zhang Bo, a research fellow at the Locomotive and Car Research Institute under the China Academy of Railway Sciences.
Current high speed rail network, 4X4 grid complete
China has 22,000-kilometers of high-speed railway, representing 60 percent of the world’s total. The network set to reach 38,000 km (24,000 mi) in 2025.
China has completed the National 4+4 grid. They are now working on a larger 8+8 high speed rail grid serving the nation and expanded intercity lines for regional and commuter services for large metropolitan areas of China. The proposed completion date for the 8×8 network is 2030.
