From biodegradable plastics to humanoid robots, a new wave of emerging technologies is on the horizon that have the potential to provide major benefits to societies and economies in the years to come, a new World Economic Forum (WEF) report said. An international Steering Committee of leading technology experts identified this year's "Top 10 Emerging Technologies" -- humanoid (and animaloid) robots designed to socialize with people; a system for pinpointing the source of a food-poisoning outbreak in seconds and minuscule lenses that will pave the way for diminutive cameras and other devices, among others. "Technologies that are emerging today will soon be shaping the world tomorrow and well into the future – with impacts to economies and to society at large," said Mariette DiChristina, Editor-in-Chief of Scientific American, and chair of the Emerging Technologies Steering Committee. Bioplastics are advanced solvents and enzymes that are transforming woody wastes into better biodegradable plastics. Like standard plastics derived from petrochemicals, biodegradable versions consist of polymers (long-chain molecules) that can be moulded while in their fluid state into a variety of forms.
A form of environmentally friendly plastic made from straw could soon be used in disposable bottles and other packaging after a breakthrough by British scientists. They have found a way to'edit' the genes of a microbe to speed up the conversion of plant material into bioplastics that break down naturally. They say using 5 per cent of the annual straw yield or 3 per cent of sugar beet crops, for example, would allow half of the 17billion plastic water bottles used in the country to be made with the biodegradable material. The bioplastic is made from lignin, the rigid material that keeps trees and plants standing. The same process could also use molecules from sugar, instead of oil, to make plastic.
Scientists have taken a major step towards reducing our reliance on fossil fuels, which could eventually save cash. For the first time, researchers managed to break down raw biomass - plant material - without using chemicals. It produced record amounts of clean liquid hydrocarbon fuel, and is an important development in a shift towards renewable energy, the scientists said.

The scientists and engineers at General Atomics think the future of nuclear energy is coming on the back of a flatbed truck. And the leadership at the San Diego-based company, which has been developing nuclear technologies for more than 60 years, has already spent millions in the expectation that its ambitious plans for the next generation of reactors will actually work. "We have technology that we think is going to qualitatively change the game," said Christina Back, vice president of nuclear technologies and materials at General Atomics. Called the Energy Multiplier Module, or EM² (EM-squared), the concept still in the development stage promises to produce electricity more cheaply, safely and efficiently than the current fleet of nuclear plants across the country. And it's designed to produce a reactor that's so compact that the company's handout material shows it being transported by tractor-trailer.
A new type of modified wood that can trap heat and then release it when needed could help buildings cut down on their energy use. Scientists say that the revolutionary material, which is biodegradable, can bear heavy loads and could open the door for'eco-friendly' homes and other buildings. The researchers, from KTH Royal Institute of Technology in Sweden, produced technically transparent wood, which allows light to pass through it. They did this by removing a light-absorbing component called lignin from the wood's cell walls and adding polyethylene glycol (PEG), which stores heat. After adding acrylic - which stops the light from bouncing around - into the porous wood, the resulting material is physically strong and and virtually clear.
