Floods, droughts, hurricanes, forest fires - once rare weather phenomena are becoming more prevalent and powerful due to climate change. And it is impossible to deny this. At the same time, more people are moving to cities around the world. This is a dangerous combination, as the urban population is more exposed to the risk of destruction from the effects of global warming. Millions of people around the world can be at risk only because of where they live now.
But the simple resettlement of populations at risk will not do anything - for example, moving a fishing village will leave people without means of subsistence, and moving industries to cities will mean more destruction of the natural environment. We need to find a more sustainable long-term solution - to create houses that are tough enough to survive frequent and extreme natural whims without increasing carbon emissions.
Experienced designers, architects and engineers worked hard to find a solution that could satisfy both of these problems: they developed houses that could survive future conditions on Earth without damaging our environment even more. Here are some of the most creative ways by which we can adapt our habitats and mitigate the negative effects of climate change.
Systemading
Systemading - the practice of creating permanent settlements on structures located in areas of the sea that are beyond the jurisdiction of any country - is becoming increasingly popular. In April 2017, this term was added to the Oxford English Dictionary, and at the same time a new way of life appeared that uses 71% of the practically unoccupied surface of our planet - the ocean.
The sea level is growing even faster than predicted by experts, so private firms, governments and researchers are increasingly turning their attention to the oceans. The open waters remote from any land are not the most attractive or accessible place for settlement, but as the ice caps melt and flooded populated areas, we may have to evolve and become accustomed to living in water.
Many projects, some in development, and some completed, set the task of turning the ocean into a new land by means of sand or embankment. Similar projects, for example, in the United Arab Emirates, significantly expanded the inhabited territory.
But adding sushi does not mean solving the problem with tides and rising sea levels. Alternative: settle on the surface of the water on a floating island.
Floating Island
The concept of a settlement on the water is not new: the inhabitants of Lake Titicaca began to build their villages hundreds of years ago on floating, interconnected rafts of floating reeds.
Seasteading Institute, a global team of biologists, engineers, investors and environmentalists, gathered in 2008 with an ambitious goal: to design a modular, fully functional and floating "eco-village". The Floating Island Project was to use concrete structures for floating platforms, also anchored at the ocean floor. These islands can be moved and rebuilt in accordance with the needs of the inhabitants of the island. Its original design allowed 250 people to live on 11 platforms with the possibility of further addition. Instead of living independently on land, the "floating island" was built especially for protected waters, and it can still be accessed from the shore.
In January, the government of French Polynesia, a collection of 118 islands stretching more than 2000 kilometers in the South Pacific, signed a memorandum with the Seasteading Institute and its affiliated Blue Frontiers start-up to begin developing a pilot floating island project as early as 2020.
Seasteading Institute proposed to build the first island village in 2020 in the lagoon off the coast of South Tahiti. Floating islands will be tied to the ocean floor about a kilometer from the shore, with platforms the size of a baseball field. "We will have a bungalow, we will have apartments, apartments, research facilities, an underwater restaurant," said Joe Quirk, president of the Seasteading Institute, in an interview with NBC News. "It will be an independent tourist attraction, a demonstration of a stable society."
The Institute will use the floating village of Tahiti to test a number of sustainable technologies, such as the use of recycled plastics and local coconut fibers as building materials. This will show whether people can live this way and whether ecotourism can be a viable basis for the local economy.
Floating islands are particularly urgent for French Polynesia - the proximity of narrow islands to the sea makes them vulnerable to rising sea levels over the next century. The newest model predicts that by 2100 under water will be from 5 to 12 percent of the islands. Thousands of residents live a few meters above sea level, so a disaster can occur at any time. And it's not just about raising the sea level - stronger and more frequent storms,

Simple processing of stainless steel has made its surface more and antibacterial.
Electrochemical etching of ordinary stainless steel allowed scientists to create on its surface complex nanostructures, unable to damage large cells of mammals, but deadly to bacteria. In the future, this will make metal tools and surfaces with antibacterial properties. Julie Champion and her colleagues from the Georgia Institute of Technology presented the novelty in an article published by the journal ACS Biomaterials Science & Engineering.
For the basis was taken a sample of steel 316L, which was immersed in the electrolyte and applied tension. Varying the parameters and current density, the scientists sought to create different surface structures. One variant demonstrated good hydrophobic properties - and, unexpectedly for the authors themselves, strong antibacterial. The exact mechanism of this action remains to be seen. In the meantime, scientists suggest that the whole thing is in the numerous knolls and sharp needles 20-25 nm high, which are formed on the steel surface during processing.
US successfully tested the latest anti-ship missile AGM-158C
As experiments have shown, they successfully cope with both gram-positive (S. aureus) and gram-negative (E. coli) bacteria, although for mouse cells are completely harmless. And since the impact is purely mechanical - most likely, the steel nanoigles simply pierce the membranes of bacterial cells - it's hard to imagine that the microbes somehow developed resistance against it

Samsung has focused on developing a smart-column and seeks to begin selling the competitor Apple HomePod and Amazon Echo in the first half of 2018.
It is expected that the size of the smart speaker Samsung will be comparable with the smart speakers already on the market. Among the colors of the shell users will be able to detect a black matte shade. The smart speaker will not be equipped with a screen, but some indicators may be located at the top, like the HomePod.
Samsung gadget will be able to control other smart devices in the house, and also take commands from the owner with the built-in voice assistant. Bixby - artificial intelligence, developed by Samsung, will be responsible for speech recognition.

Information about the possible appearance of a smart column from the South Korean corporation was promulgated in August 2017. Samsung intends to release a gadget worth about two hundred dollars. This will make the smart speaker much more affordable than the Apple HomePod, which will cost $ 349.
Apple planned to release a smart column in December 2017. However, for unknown reasons, the start of sales was postponed to 2018. Perhaps, the devices of the leading manufacturers of mobile devices will enter the market simultaneously.
