    British-born scientists David Thouless, Duncan Haldane and Michael Kosterlitz have won the 2016 Nobel Prize for Physics for their studies of unusual states of matter, which may open up new applications in electronics.
    Their discoveries, using advanced mathematics, had boosted research in condensed matter physics and raised hopes for uses in new generations of electronics and superconductors or future quantum computers, the Royal Swedish Academy of Sciences said.
    "Thanks to their pioneering work, the hunt is now on for new and exotic phases of matter," the academy said in a statement awarding the 8 million Swedish crown ($A1.2 million) prize.

    Dr Thouless was awarded half the prize with the other half divided between Mr Haldane and Mr Kosterlitz.
    Nils Martensson, acting chairman of the Nobel Committee for Physics, told a news conference the winners had discovered a set of totally unexpected regularities in the behaviour of matter.
    "This has paved the way for designing new materials with novel properties and there is great hope that this will be important for many future technologies," he said.
    Physics is the second of this year's crop of Nobels and comes after Japan's Yoshinori Ohsumi was awarded the prize for medicine on Monday (local time).
    As Nobel physics laureates, the trio of researchers join the ranks of some of the greatest names in science, including Albert Einstein, Niels Bohr and Marie Curie.
    The prizes were first awarded in 1901 to honour achievements in science, literature and peace in accordance with the will of the Swedish dynamite inventor and business tycoon Alfred Nobel, who left much of his wealth to establish the award.

    Yesterday it was a British trio. Today it is a trio of European scientists who have bagged the Nobel prize in chemistry for developing "nano-machines".

    The winners are Dutchman Bernard Feringa, Sir Fraser Stoddart from Scotland, and France's Jean-Pierre Sauvage. The trio will split the 8 million Swedish Kronor prize three ways. The winners were announced by the Royal Swedish Academy of Sciences in Stockholm on 5 October.

    "They developed the world's smallest machines," read the headline of a statement on the Nobel prize website. How small? According to the statement, the scientists won the award for "the design and synthesis of molecular machines".

    Sauvage is at the University of Strasbourg, France, while Stoddart is at Northwestern University, Evanston, Illinois, USA and Feringa belongs to the University of Groningen, the Netherlands.

    "I feel a bit like the Wright Brothers," Feringa said in a phone call to the Royal Swedish Academy of Sciences Wednesday, where the prize was announced. "People were saying, why do we need a flying machine? Now we have a Boeing 747 and an Airbus. That's a little bit how I feel. The opportunities are great."

    Medical micro-robots and materials that respond to external signals are being developed using the technology pioneered by the three.

    As The Guardian explained it, "Together, the chemists designed some of the first controllable, nanometre-sized structures that can convert chemical energy into mechanical forces and motion. This allowed them to construct a host of molecular devices, including switches, motors, shuttles and even something resembling a molecular motorcar".

      100 per cent renewable energy network affordable, secure and 'off the shelf': study

      Australia can build an affordable and secure electricity network with 100 per cent renewable energy, using existing technologies, according to research by the Australian National University (ANU).
      So how would it work?

      The study details plans for a zero-emissions grid which would rely on wind and solar technology, supported by pumped hydro storage.
      It could be set up with inexpensive, currently available, "off the shelf" products and eliminate the need for coal and gas-fired power.
      At the moment, two-thirds of Australia's electricity comes from coal-fired power stations but as they age and close like Hazelwood will in Victoria next month a reliable baseload capacity replacement must be found.
      Climate politics in 2017: a guide

      In 2017 Australia will review its climate policies, and the process is not off to a good start, writes Marc Hudson.

      Affordable, reliable, but 'hard to swallow' for some

      Professor Andrew Blakers from the ANU said wind and solar can be that replacement, with the support of off-river pumped hydro, where reservoirs at different altitudes can be used to store and generate power.

      Professor Blakers is the lead author on the study which has found that by using solar and wind energy, supported by pumped hydro, Australia can have a cheap, stable, zero-emissions network.
      The research follows Energy Australia's announcement last week it will investigate an off-river pumped hydro venture at the top of South Australia's Spencer Gulf.
      "Ninety-nine per cent of the Australian land mass is not near a river and we're finding hundreds and thousands of sites, all the way from north Queensland, down the Great Dividing Range and across to South Australia, Tasmania, Western Australia," Professor Blakers said.
      "The primary aim was to find out whether we could go to 100 per cent renewable electricity while using only common, off-the-shelf items that have very well established prices. The short answer is, 'yes'."
      So how much would it cost?

      Modelled on current prices, Professor Blakers said the cost would drop from $93 a megawatt hour in 2016, down to $75 a megawatt hour in the 2020s.
      "The affordability is there, photovoltaics and wind are now cheaper than gas and coal and will get much cheaper over the next decade," Professor Blakers said.
      "The reliability is there because we have done very careful, hour-by-hour analysis of the Australian electricity grid and we find that with a modest amount of storage and some increased interconnectors within the states, the entire stability can match anything coal and gas can deliver."
      Who supports it?

      The plan has some strong backing the Government's own Renewable Energy Agency kicked in $450,000 for the research.
      Dylan McConnell from Melbourne University's Climate and Energy College said Australia needs to accept these are the energy systems of the future.
      "The concept of baseload is basically an outdated concept we need technologies that can meet our needs as they're required," Mr McConnell said.
      "That is, they need to be dispatchable and reliable, when we actually demand them."
      While he fully supports the research, he admits, right now, it will be hard for some to swallow.
      "The lack of bipartisan support around energy policy will make this a challenging piece of research to accept in the current political climate, but it's still a very important contribution that needs to be taken seriously by all sides of government," he said.
      Not everyone has welcomed the findings

      Australian Energy Council CEO Matthew Warren said it wasn't the time for 'intellectual' proposals.
      "Talking about 100 per cent renewables right now is the wrong question," Mr Warren said.
      "We're dealing with real world problems of 50 per cent renewables in South Australia and consequences for that around the rest of the country.
      "These are really material challenges in the real world."
      Mr Warren said Australia was at an urgent juncture, where "intellectual exercises" like these, along with the politicising of the energy debate, have to make way for action.
      "The fear is that things get worse before they get better, that we need severe crisis to galvanise political alignment, and that would be unfortunate because we can see that's coming," he said.
      "We're already in a state where we can see conditions deteriorate before they improve because it will take us time to invest to restore the grid to a high-functioning level, so we don't have a lot of time."

                      Tesla boss Elon Musk pledges to fix SA's electricity woes in 100 days 'or free'

                      Billionaire tech entrepreneur Elon Musk has joined the throng of entrepreneurs pitching potential solutions to South Australia's power woes.
                      But the boss of Tesla and Space X has made an intriguing pitch declaring his company could install a battery farm capable of "fixing" the system within 100 days, or else do it for free.

                      South Australia suffered a statewide blackout last September, while during a recent heatwave customers were intentionally blacked out because there was not enough power to meet demand.
                      Mr Musk backed up a suggestion by his vice president for energy products, Lyndon Reve, that they could help prevent increasingly regular blackouts in South Australia.
                      "Storage can solve the immediate problem within the next 100 days," he told ABC News.
                      Tesla has been spruiking its Powerwall 2 and Powerpack 2 battery products in Australia this week.
                      Mr Reve said Tesla had recently completed a similar challenge in California after a methane leakage at a gas peaking plant.
                      "From start to finish, we installed an 80MWh battery pack at one of the substations in Southern California," he said.
                      "We can do the exact same thing in South Australia. Storage is the technology, and it can solve the problem within the next 100 days or so."
                      The startling claim certainly caught the attention of another billionaire tech guru.
                      "Holy s#%t" tweeted Australian Mike Cannon-Brookes, who co-founded software company Atlassian.
                      It was at that point that Mr Musk, the South African-born Tesla chief, doubled down and shot a tweet confirming the 100-day boast and ending with: "That serious enough for you?"
                      Mr Cannon-Brookes tweeted this afternoon, asking the Tesla boss for "mates rates" and time to sort things out.

                            Prime Minister Malcolm Turnbull says he has held a "great in depth discussion" with Elon Musk, after the billionaire tech entrepreneur offered to fix South Australia's energy problems within 100 days.
                            On Friday, Mr Musk said energy storage could solve the state's electricity problems with a Tesla battery farm, and work could be completed within 100 days, or it would be free.
                            He followed that up in talks with South Australia's Premier Jay Weatherill, later tweeting that he was impressed by the State Government's commitment to a "smart, quick solution".
                            Twitter was again the preferred medium of communication on Sunday, with Mr Musk and Mr Turnbull swapping appreciative tweets after speaking for nearly an hour.

                            How energy storage could help

                            South Australia's energy network has been struggling and Tesla thinks it has a solution.

                            A statement from the Prime Minister's Office said that: "The pair had an in-depth discussion on the value of storage and the future of the electricity system".
                            Yesterday, Mr Weatherill said he was keen to discuss the matter further with Mr Musk and was "certainly not ruling it out".
                            The idea also had the support of Opposition Leader Steven Marshall, who urged Mr Weatherill to consider the proposal.
                            While it is not clear what an array in South Australia would cost, Tesla did deliver on a battery farm in Southern California, built using an array of 400 Powerpack 2 batteries.
                            South Australia suffered a statewide blackout last September, while during a recent heatwave customers were intentionally blacked out because there was not enough power to meet demand.
