A few days ago, a wildfire spread around the world the news of the appearance of a new coronavirus-nCoV 2019 on the Japanese ship called the Diamond Princess. Today, passengers going through the scene like a horror movie.
The unit is currently docked in the port of Yokohama. 3645 passengers and crew members were quarantined. The city authorities say that the virus has already infected 135 people, and this number will grow. Passengers are experiencing a real tragedy, because no one knows who is a carrier of the virus from Wuhan.
The problem is that medical services are not able to examine up so quickly such a large number of people. At the moment it indicates approx. 200 people who may be infected. We must remember that this pathogen moves asymptomatic, so the potential infected and infect others at the same time can be all and without symptoms of fever and discomfort typical for this type of disease.
The researchers suggest that to detect the virus in 2019-nCoV need to perform up to three tests, nucleic, and it not only takes a few days, but it still does not have a place where people already infected and those suspected about it. Pathogen can also infect several times.
Yokohama authorities say that the first person on the ship, in which coronavirus was detected, it was 80-year-old Chinese citizen. January 25 was blown ashore in Hong Kong and passed medical services. Despite this, earlier he had already infect a few people and the virus began to spread rapidly.
Currently, the world is the 813 victims of the virus and infected nearly 40,000. The Chinese authorities do not hide that the first effective drug for the new coronavirus can occur only after 2-3 months. However, you need to emphasize here that it may not be effective for all mutations of the virus, so the hope of survival may concern only as a specific group of people.
Thanks to the commitment of engineers and scientists, today’s batteries are much smaller and manageable than in the past, but in many cases this is not enough. Those placed in accessories to wear are the most common size and shape of a small coin, and although it would seem that there is no such device, in which will not fit, then with the increasing miniaturization of technology are often already too large. In short, we need a breakthrough to fully enjoy the possibilities of modern accessories.
I predict such a breakthrough, researchers from Stanford University, who developed a battery that is soft, flexible and a lot safer than the ones used today. Instead of the adhesive and viscous reached this purpose the polymer retains a more stable form, such as a pencil eraser or rubber band. This is able to store enough energy to power small electronics and at the same time is non-flammable, giving him a big advantage over current solutions.
Presented by scientists prototype is the size of a fingernail on the thumb and store as much energy as conventional batteries. Moreover, it retains its properties even when it is compressed, folded and stretched, and can thus increase almost twice its length! You also can not forget that in this case there is no risk of chemical leakage or explosion, because we are not dealing with the polymer in the form of a gel, as in typical batteries, so accessories to wear with a new type of battery will be much safer.
– Until now we had no energy source that could stretch and bend in such a way to adapt to our body and enable the production of electronic accessories, which are really comfortable to wear – says Zhenan Bao of Stanford University. Now it has to change, and scientists say that one of the most important applications may here be flexible sensors glued to the skin in order to monitor heart rate. Later, while we expect the larger versions of these batteries, which will go to larger devices and will be characterized by greater energy density.
Glaciers do not melt only at the top, but under the water, of which we are well aware, but due to the nature of this process, we are not, at least we were able to follow it exactly.
Scientists can not just go under the water to watch held up the melting of glaciers, so far we did not realize how fast this is happening – now thanks to robotic kayaks we have a much better understanding of this phenomenon and unfortunately are not good news . LeConte Glacier in Alaska, the glacier which is almost 32 km long river of ice, which is located in the mouth of the ocean, is the best proof. In the latest study, researchers wanted to focus on how and to what extent the ice melted in the meeting room with the sea, but the classical methods were too dangerous, due to the regular pieces of ice falling off.
So he sent a team to place robotic kayaks, which have been programmed to swim close to the ice cliffs and measure, hives fresh water flows into the ocean from the glacier. This unique type of melting has not been tested, due to the enormous risk of such studies, so the researchers had to rely on the estimated models. They assumed that the melting will be less than it is at the top of the glacier, which has contact with the air and lost large portions. Meanwhile, it turned out that we were wrong … completely wrong, because melting occurs under water up to 100 times faster!
– The kajakom discovered surprising symptom melting layer concentrated water from the melting of glaciers drop into the ocean disclose critical process hitherto ignored in the modeling and estimates the rate of melting – claims study author, Rebecca Jackson. The new studies are not the only ones who want to look under the surface of the water, because in the last year thanks to NASA radar satellites have discovered a huge cavity below the Thwaites Glacier in Antarctica, which previously contained 14 billion tons of ice. Other studies have indicated and that water from melted glaciers alters the composition of ocean water surface, which can speed up the pace of raising the water level.
