All of us have been taught in school that fossil fuels are a finite resource because there's only so much oil in the ground. But going completely green would require a shift in living patterns and could be very challenging for society. We have to think about future generations and provide them with an alternative energy source before we run out of fossil fuels. Nuclear fusion is a clean, safe, and sustainable energy source that has been researched for decades but has not been commercially successful because the conditions required to maintain it are hard to achieve. This may change soon because scientists at MIT have created a new device that uses lasers to produce the necessary magnetic field, taking away one of the major obstacles that previous attempts faced. This will create an artificial star that will act as the main driver in the fusion process, creating more energy than it can consume. It might seem like having a tiny computer in your body is much too futuristic to ever happen—but, in fact, this is something that has existed since 2004 when one of the first nanorobots was manufactured. Today nanorobots are used in particular applications like healing and drug delivery. Given this new advancement, it might be possible to use nanorobots for self-healing or would would be able to repair damaged body tissues. Researchers at MIT were able to make microscopic robots using DNA strands that could act like biological motors; these could help repair tissue. Molecules that can take on a number of shapes as required by their needs are evolving as scientists create new materials from them. Scientists at the University of New South Wales have been able to synthesize a material that can go from a flat sheet to a tube, and back again, with the help of a certain agent—the first time this has ever been achieved. This new tool will make it possible for researchers to study the effects of various compounds on other molecules, and will also help them understand how quantum mechanics can be used in creating these new materials. Self-driving vehicles are already being tested in the United States, and not long from now they may be common.This technology is being made possible by various systems that together create vehicles that are able to drive without the help of a driver. But even though these vehicles are gaining popularity, they have also been met with opposition due to their potential vulnerability to hacking among other things. Legislation is being put in place to prevent self-driving cars from causing accidents or being used for malicious purposes. Here are some simple ways you can save water. Water Conservation for the Home Rainwater harvesting is important because it is a sustainable, clean alternative to treated wastewater. It also allows water that would otherwise be wasted to be used for irrigation, cleaning, and other purposes. There are a few ways that you can help conserve water in your home: Cleaning your gutters will reduce the amount of rainwater going into your soil and improve your drainage system by ensuring that all debris has been removed from it. Planting different types of plants around your home will help lessen any potential damage from flooding or erosion due to heavy rainstorms. cfa1e77820
