Large business actively uses drones and 3D printers
Trends of business in the world: we print houses and cars
The world actively implements scientific discoveries in everyday life. The living of people in houses or driving cars printed on 3D printers is already becoming a reality - although five years ago people perceived these printers as entertainment, which prints in a cafe a toy while a visitor drinks coffee. Similarly, unmanned cars and ships that save the ecology of tires and innovative materials that generate water in the desert break into our daily routine.
But a real breakthrough is still to be expected in medicine. Researchers suggest patients to abandon habitual needles, use nanorobots to treat cancer, and replace painful glucometers with patches that measure blood sugar levels. "Today" has studied the main trends of business and technology abroad.

Medicine: pain is a thing of the past
The secret of immortality science has not yet revealed. But thanks to innovations, medicine can soon abandon injections, and the operations will be carried out by nanobots.
How did a mosquito bite
American scientists from the University of Texas at Dallas using 3D print created microscopic needles. When such a prick is injected into the skin, the needle dissolves, spreading the medicine. The tip of the needle is one micrometer. For comparison: the width of human erythrocyte - 5 micrometers. True, ultrathin needles are suitable only for drugs consisting of small molecules.
Nanorobots
Researchers from the Chinese Center for Nanoscience have created autonomous DNA nanorobots, whose task is to combat bad tumors. Bots are 5000 times smaller than the tip of the needle, and have a tubular structure. The length of the bot is 90 nanometers, the diameter is 19. It is expected that nanorobots will be able to find tumors and block the blood supply of malignant formation, after which the tumor should collapse in a few weeks. Scientists have already been able to achieve successful results thanks to experiments on mice and mumps.
Patch
678
Scientists from the British University of Bath have developed a plaster that measures the level of glucose in the body without blood sampling. For the analysis, he uses a tissue fluid that cleans the cells of the hair follicles. How does the gadget work? The patch consists of four sensors. It is attached to the skin so that at least one sensor is located above the hair follicle. After the patch captures the tissue fluid in a small chamber with hydrogel, which contains glucose oxidase. This substance reacts with glucose to form hydrogen peroxide, which allows the sensors to determine the level of sugar in the body. Scientists have already tested the invention in humans: the device was able to analyze the sugar level every 10-15 minutes for 6 hours.

In the desert there will be water
American scientists from the Massachusetts Institute of Technology and the University of California at Berkeley have learned to collect water in the desert. To do this, metamaterial - metal-organic frame (MOF) is created. It consists of bound molecules that create a superporous large surface area. MOF attracts moisture: at night it extracts water from the air and stores it in the pores, and in the daytime the water condenses, which allows it to be collected. As a result, a kilogram of MOF can save 250 ml of water per day in a dry desert.
Ecology: tires from live moss will purify the air
333
Ecotechnologies are becoming more revolutionary. So, the Dutch scientists from Wageningen University have created a DNA test that will help identify ... illegally cut trees! To this end, several hundred samples of wood species were tested, in particular from Cameroon and the Republic of the Congo. This information helped create an impressive database of tropical trees. And now scientists can determine the radius of the territory where the tree grew, with an accuracy of 14 km.
In the meantime, manufacturers are trying to solve environmental problems. Breakthrough in the prospects of producing oxygen was made by Goodyear. Its representatives demonstrated to the public car tires Oxygene: they managed to place live moss directly under the rubber! Now the tires can absorb carbon dioxide and moisture from the air to feed the moss inside the tire, and the moss will in turn produce pure oxygen. The company estimates that every year a 2.5 million cars fleet with Oxygene tires will produce 3000 tons of oxygen and absorb 4000 tons of carbon dioxide.
The tooth sensor keeps track of food and alcohol

People's diet will soon begin to monitor special dental sensors. Innovative gadgets measuring 2х2 mm can be fixed on the surface of the tooth and monitor how much glucose, salt or alcohol is consumed. "The device consists of three layers, the two external are the antennas for signal transmission, and the third, the bioabsorbent, keeps records and recognition of nutrients, the data is transferred to the application in the smartphone," explain specialists from the Tufts University Engineering School.
