Bio-composites for cars
Bio-composites for cars Bio-composites have become increasingly popular with car manufacturers because they can reduce vehicle weight, which improves performance and lowers CO 2 emissions .
Superfast all-RAM processors could bring high-performance computers to the masses
Superfast all-RAM processors could bring high-performance computers to the masses Today’s computer processors are pretty fast. Under optimal conditions, a desktop can come close to teraflop speeds, which is a million million operations per second .
Bio-based alternatives to plastic plant pots
Bio-based alternatives to plastic plant pots In recent years, plastic pollution has hit the headlines as a major environmental issue. While gardening is an outdoor activity involving organic material and natural products, the uncomfortable truth is that gardeners use a lot of plastic .
Saving lives during cancer surgery by separating the good from the bad
Saving lives during cancer surgery by separating the good from the bad Identifying healthy from diseased tissue poses a unique problem for cancer surgeons. Even the smallest bits of a tumour left behind during surgery can regrow and spread to other organs, a deadly phenomenon called metastasising.
Levitation becomes a reality
Levitation becomes a reality Levitation is an old dream of humankind. For centuries, magicians gave audiences the illusion of defying gravity, seemingly making objects of people float into the air. Now European scientists are turning this into reality.
Electric mobility: opportunities and challenges
Electric mobility: opportunities and challenges Greenhouse gases decreased by 23% between 1990 and 2016, said the third report on the state of the “Energy Union”, which tracks the EU's transition to a low-carbon society.
When science challenges terrorism
When science challenges terrorism Can science become central to combating terrorism and organised crime? Predictive policing uses mathematical and analytical tools to identify potentially dangerous people and forecast crimes.
How battery systems can integrate renewable energy in smart grids
How battery systems can integrate renewable energy in smart grids Wind and solar energy is not constant and therefore a renewables-based society requires smart grids to transport this power from areas where electricity generation is currently high to those where it is low in order to meet demand.
Meet the skyrmions: exotic quasiparticles could revolutionise computing
Meet the skyrmions: exotic quasiparticles could revolutionise computing For most of us, any concerns about computing speed or data storage are usually to make it go faster while storing more. We hardly ever think about the enormous amounts of energy already required to power Internet servers or charge the increasing number of devices we own.
Liverpool, a frontrunner city in re-naturing public spaces
Liverpool, a frontrunner city in re-naturing public spaces If you happen to swing by Liverpool in the future, you will probably see a tree urban drainage system in Bold Street, where people frequently shop. Surface water flooding is a problem in many cities.
Offshore wind farms: too much energy is lost in cables
Offshore wind farms: too much energy is lost in cables Offshore wind farms play an increasingly important role in renewable power generation. According to WindEurope, Europe now has a total installed offshore wind capacity of 15,780 MW.
How machines can learn from human behaviour
How machines can learn from human behaviour Could a human behaviour simulator be embedded into a robot or online avatar to the point that it’s hard to distinguish between a real person or artificial intelligence? Scientists have been upping the stakes in this “ Turing test ” for years, to the point that human-mimicking programmes are ready to answer tricky questions, assist people with online shopping or be companions.
How can smart cities finance their transformation?
How can smart cities finance their transformation? Local governments in Europe are notoriously risk averse, city council officials and industry leaders won’t hesitate to tell you.
Bio-homes to tackle the housing emergency
Bio-homes to tackle the housing emergency Bristol is at the forefront of high-tech innovation in the UK, named European green capital in 2015. But it is also the second least affordable major British city housing-wise only after London.
Soy filters: a cheap solution for air purification
Soy filters: a cheap solution for air purification Researchers in the US have developed bio-based air filters that they claim can capture toxic chemicals that current filters can’t.
Small aircraft to find water leakage
Small aircraft to find water leakage In about half of the EU countries, more than 20% of clean drinking water is lost in the distribution network before it reaches consumers’ taps, and in some countries the proportion is as high as 60%, stated a report by the European Commission.
Life is LiFi in smart buildings
Life is LiFi in smart buildings Just imagine: you get back home one evening, unlocking your door with the torch light of your mobile. You sit down on your sofa, download a film 100 times faster than currently possible and enjoy the movie on a fully secure wireless connection.
How supergrids can support the integration of renewable energy
How supergrids can support the integration of renewable energy In the past, most electricity grids were mainly based on centrally produced power, in relatively few plants, within national borders.
The City for Tomorrow
The City for Tomorrow A new research conducted by world leading emissions experts is painting a rather gloomy picture. Due to stronger economic growth, global greenhouse gas emissions have hit a new record high of 37 billion tonnes of dioxide in 2017.
