EV Charging Answer: Quantum Technology Will Cut Time it Takes to Charge Electric Cars to Just 9 Seconds:
Institute for Basic Science
Scientists in South Korea have proven that a new technology model will cut the time it takes to charge electric cars to just nine seconds, allowing EV owners to ‘fill up’ as fast as their gasoline counterparts. Even those plugging in at home will have the time slashed from 10 hours to three minutes. The new device uses the laws of quantum physics to power all of a battery’s cells at once instead of one at a time, so recharging takes no longer than filling up at the pump. Scientists at the Institute for Basic Science (IBS) in South Korea have come up with the model for the super-fast charging station and have found through research that it allows a common electric car with 200 cells to charge 200 times faster than a conventional charging station. Though this model has yet to be applied to a physical charging station prototype, it has the potential to revolutionize the car market and save more time in our fast-paced world.
New study solves mystery of how soft liquid droplets erode hard surfaces:

A first-of-its-kind study led by University of Minnesota Twin Cities researchers reveals why liquid droplets have the ability to erode hard surfaces. Using a newly developed technique, the researchers were able to measure hidden quantities such as the shear stress and pressure created by the impact of liquid droplets on surfaces. It's common knowledge that slow-dripping water droplets can erode surfaces over time, but why can something seemingly soft and fluid make such a huge impact on hard surfaces? Using a technique called high-stress speed microscopy the researchers at the University of Minnesota were able to measure quantitatively the force, stress, and pressure undeath a dropping water droplet. They found that instead of the force being concentrated at the center of the droplet, the force extends in a shockwave as the water droplet spreads out on impact, sometimes faster than the speed of sound. Thus, each droplet behaves like a small bomb, releasing its impact energy explosively and giving it the force necessary to erode surfaces over time. Besides paving a new way to study droplet impact, this research could help engineers design more erosion-resistant surfaces for applications that must weather the outdoor elements.
We finally have a fully complete human genome:
New technologies that allow scientists to put DNA bases, represented by the letters A, T, C and G, in order have helped researchers put together one of the world’s most complex puzzles, a complete human genome
Researchers have finally deciphered a complete human genetic instruction book from cover to cover. An international team of researchers, including Eichler, used new DNA sequencing technology to untangle repetitive stretches of DNA that were redacted from an earlier version of the genome, widely used as a reference for guiding biomedical research. Deciphering those tricky stretches adds about 200 million DNA bases, about 8 percent of the genome, to the instruction book, researchers report in Science. The new deciphered genomes contain the first-ever looks at the short arms of some chromosomes, long-lost genes, and important parts of chromosomes called centromeres where machinery responsible for divvying up DNA grips the chromosome. New patterns in the sequencing of DNA strands, new variants of DNA, and gene regulation mechanisms have been discovered which has furthered our understanding of what changes occur within genes to make us who we are. Furthermore, due to the newly completed genome biomedical scientists may give scientists a much better understanding of markers for genetic disease, changes in human medical condition, and how exactly we evolve. Much of the genome discovered was that of European descent, and due to this new research is being conducted to see how other geographic and racial genomes differ across the world.
