Google's driverless car- The Waymo

-

The car's arrival marks the next stage in Google’s self-driving car project, which was born from the Darpa Grand Challenges for robotic vehicles in the early 2000s. Google kickstarted its own self-driving car project in 2008, and it has been rumbling on ever since, first with modified Toyota Prius and then with customised Lexus SUVs, which took the car’s existing sensors, such as the cruise-control cameras, and added a spinning laser scanner on the top.
It ferries two people from one place to another without any user interaction. The car is summoned by a smartphone for pick up at the user’s location with the destination set. There is no steering wheel or manual control, simply a start button and a big red emergency stop button. In front of the passengers there is a small screen showing the weather, the current speed and a small countdown animation to launch.
Once the journey is done, the small screen displays a message to remind you to take your personal belongings – reinforcing that this is not aiming to be a substitute for your personal car at the moment, but more as a replacement for the taxi without the human driver.
Google has designed the car from scratch, starting with the sensors and a frame to interconnect them, then adding a cabin that does not block any of the sensors or create blind spots and eventually the body shell. The manufacturing of the 100 or so prototype cars will be done by a firm in the Detroit area, but Google declined to comment on which.
Powered by an electric motor with around a 100 mile range, the car uses a combination of sensors and software to locate itself in the real world combined with highly accurate digital maps. A GPS is used, just like the satellite navigation systems in most cars, to get a rough location of the car, at which point radar, lasers and cameras take over to monitor the world around the car, 360-degrees.
The software can recognise objects, people, cars, road marking, signs and traffic lights, obeying the rules of the road and allowing for multiple unpredictable hazards, including cyclists. It can even detect road works and safely navigate around them.

The new prototype has more sensors fitted to it that can see further (up to 600 feet in all directions) and in greater detail than the ones available on the previous repurposed Lexus and Toyota vehicles. MY REFERENCE

Korean electric vehicle solution

-
Image
The Advanced Institute of Science and Technology (KAIST) have developed an electric transport system where the vehicles get their power needs from cables underneath the surface of the road via non-contact magnetic charging. Besides potentially saving Korea a lot of money by reducing crude oil imports, widespread adoption of the technology also offers the potential of improving air quality in currently polluted cities for example those in China. The drive towards adoption of the electric vehicle as a popular and viable means of transport is beginning to highlight a few potential road blocks which may not be enough to halt progress but may require some inventive thinking. Limitations on battery size and power, the issue of battery weight, the range of an electric vehicle between charges, how long it takes to recharge the batteries, and not forgetting the availability of charging points and who foots the bill - all currently hot topics in the world of electric vehicle creation. ...

CRISPR 2.0

-
You’ve probably heard of the molecular scalpel CRISPR-Cas9, which can edit or delete whole genes. Now, scientists have developed a more precise version of the DNA-editing tool that can repair even smaller segments of a person’s genome. In two studies published this month, one in  Nature  and another in  Science , researchers from the Broad Institute of MIT and Harvard describe a new way to edit DNA and RNA, called base editing. The approach could one day treat a range of inherited diseases, some of which currently have no treatment options. The human genome contains six billion DNA letters, or chemical bases known as A, C, G and T. These letters pair off—A with T and C with G—to form DNA’s double helix. Base editing, which uses a modified version of CRISPR, is able to change a single one of these letters at a time without making breaks to DNA’s structure. That’s useful because sometimes just one base pair in a long strand of DNA ...

How to fight sleep while studying.

-
So I have occasionally suffered from sleep during my lectures and studying periods until when it finally hit me. For some reason, if you just keep breathing, I mean breathing consciously (Oh God I know you aren't dead and are obviously breathing), you don't fall asleep hihihi. This really sounds stupid. If anyone out there wants to try it, please try and help me confirm that it actually works. So it turns out, for you to sleep, you must actually sort of hold your breath for a while, then blackout. I mean, at that moment of blacking out, you actually do hold your breath. Well, so all you have to do now is to make sure you don't hold your breath- like at all, and you are all set.
