New Generation Batteries that could bloster up electric car development

-
As many scientists and enterprises see the next generation of energy storage device, a new type of battery using metal and air has been considered a "dream battery" with cheap production costs and high capacity. 

A group of chemists in Korea, led by the Ulsan National Institute of Science and Technology (UNIST) professor Kim Gun-tae, has succeeded in developing a key catalyst to realize the "metal-air" battery, according to the institute. 

The  development of the new catalyst is expected to expedite the commercial launch of metal-air batteries. 

 Their work was revealed in global materials science journal ACS Nano's Oct. 20 edition. 

Currently, lithium-ion batteries are the most widely used type of secondary fuel cell, especially in small electronics devices such as smartphones. But theoretically, it is difficult to further increase the energy density of these due to technical limits. 

For this reason, research for new mid- and large sized batteries to replace them has been gaining momentum around the globe to meet expanding demand from the electric vehicle market. The metal-air battery has also been highlighted as one of the candidates. 

Compared to other electrochemical cells, the metal-air battery has a simpler structure and uses cheaper materials. Still, it has high electrical capacity and does not create pollutants. For this reason, two types of metal-air batteries ― lithium-air batteries and zinc-air batteries ― have been the most promising candidates for next-generation electric cars. 

It is anticipated that  the participation of global enterprises in the development of metal-air batteries will speed up the process. 

"Though the new battery still needs time to be actually released in the market, technological issues will be addressed shortly as many global enterprises such as Samsung Electronics, Toyota and IBM are heavily investing in the new battery."

Korean electric vehicle solution

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.
