Married women working full time who hired cleaners devoted an average 60% of the hours they saved to their own paid employment It was not possible to conclude a direct cause and effect link, since it could also be the case that couples purchased more cleaning services as a result of their income increasing rather than vice versa One study found that monitoring individuals' carbon footprint led them to cut emissions by 18% (Credit: Getty Images) Grassroots carbon reduction efforts also sidestep the prickly issue of policing lifestyle choices Declining costs associated with solar energy is also an incentive In the Norfolk Island study, participants were set a goal of reducing their fossil fuel use by 10% over the course of the study Now, the low clouds that cover their towns with mist is changing that We store about 20kg of hydrogen, and that is enough to run the fuel cell for three hours, says Stuart Hillmansen, professor at Birmingham University and leader of the Hydroflex project But we have some recovery in this area, he adds, which would increase the likelihood of bat turbine collisions But for a company to invest in making reactors and their components, it would need a reliable market, and many private investors are still wary of the new technology Engaging local elites and politicians could do more good than working with individual farmers, says Purnomo We didn’t talk too much about what he’d done on the Moon At the moment, the 90m high (297ft) gantry is just a giant framework of girders, but in the coming months it will be covered in metal panels and the interior fitted with decks to encase the rocket We have these new frontiers, space is just the latest one which might be open It’s also possible there simply isn’t any life there yet One concept, for a nuclear powered tunnelbot to search for life on Europa, was presented at a 2018 meeting of the American Geophysical Union in Washington DC, by scientists at the University of Illinois at Chicago and Nasa Six months on the ISS is not exactly a walk in the park, so the basic astronaut selection process would be the obvious place to start Griffin turned to the Capcom (capsule communicator) responsible for talking to the crew, Jerry Carr And then I came to ILC to work on the Apollo spacesuits and everything was very slow One in five of our workforce is suffering mental stress at any given time Yet employers know that distracted workforces mean lost productivity Watering down the rules might open the door to worker abuse, says Germany’s Federal Institute for Occupational Safety and Health BAUA Herndon’s team named their robot Duncan, after a mission when the robot glitched and began spinning in circles, or doughnuts (doughnuts led to Dunkin Donuts, hence Duncan) You can tell just by taking a deep breath how much it is a mechanical act, explains Donald Noble at Emory University in the US F1 and the FIA say they have been following the advice of local authorities as to whether events can go ahead In Australia he circulated among the political elite, and even after his conviction he received public statements of support from two former prime ministers
