Management row threatens to blow Sahara solar dream

Plans to supply Europe with electricity generated in North Africa suffered another blow this week when the DESERTEC Foundation, set up in 2009 to promote the idea, pulled out of the industrial consortium which is trying to advance the €400 billion project.  Read more

Canadian accelerator produces a city’s-worth of medical isotopes overnight

Canadian accelerator produces a city’s-worth of medical isotopes overnight

The looming problem of a global medical isotope shortage is one step closer to a solution. A Canadian team has developed an upgrade that allows hospital cyclotrons to make a much-needed diagnostic tracer, and has proven it can pump out enough overnight to fulfil a city’s needs the next day.  Read more

Commercial access to suborbital space still on the horizon

Commercial access to suborbital space still on the horizon

BROOMFIELD, COLORADO — In a packed hotel ballroom within sight of the Rocky Mountains, entrepreneurs and researchers gathered on 3 June to discuss their sky-high dreams for commercial spaceflight. One day soon, they say, private spaceships will zip aloft on a daily or even hourly basis, for a brief taste of zero gravity in suborbital space. Tourists will line up for rides, while scientists hop on board to do planetary science, materials research, and even human physiology studies.  Read more

Political thaw raises hopes for refrigerant regulations

This week China budged. Depending on one’s perspective, it wasn’t much of a concession. The country agreed, in essence, to do what it and everybody else had already agreed to do back in 2007: accelerate the phase out of a common class of ozone-eating refrigerants that double as powerful greenhouse gases. But rather than haggling over prices each step of the way, China made it simple and cut a single deal – worth up to $385 million – to eliminate hydrochlorofluorocarbons (HCFCs) between now and 2030.  Read more

Further proof for controversial quantum computer

Is the world’s only commercial quantum computer really a quantum device, or a just regular computer in disguise? Controversy has long swirled around the computer produced by D-Wave, a company based near Vancouver, Canada. Now a paper published on the arXiv preprint server takes a step forward in showing that it really does operate on a quantum level.  Read more
