An inconvenient truth: Does responsible consumption benefit corporations more than society? Posted: 26 Aug 2014 08:29 AM PDT Are environmental and social problems such as global warming and poverty the result of inadequate governmental regulations or does the burden fall on our failure as consumers to make better consumption choices? According to a new study, responsible consumption shifts the burden for solving global problems from governments to consumers and ultimately benefits corporations more than society.

Nuclear legacy of Hiroshima is a global issue, but the challenge is: How much of it is a trauma for everybody? Posted: 26 Aug 2014 08:29 AM PDT Speaking in Hiroshima of the bombing of the city, Yoko Ono stood up for peace declaring that 'No More Hiroshima' is a global issue. In light of the continued legacy of the event, a new study  looks at how the Hiroshima story penetrated into the realm of Japanese public memory and investigates whether the trauma became a truly national one. Crucially, the research questions if the transformation from a circumscribed experience to a society-encompassing one was a natural experience or a constructed phenomenon instead.

Introducing the multi-tasking nanoparticle Posted: 26 Aug 2014 08:26 AM PDT Dynamic nanoparticles (NPs) have been developed that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors. In addition, the particles are biocompatible and have shown no toxicity.

Key to speed? Elite sprinters unlike other athletes, deliver forceful punch to ground Posted: 26 Aug 2014 07:08 AM PDT The world's fastest sprinters have a distinctive ability unlike other runners to attack the ground and attain faster speeds, according to new research. The new findings indicate that sprinters use a combined limb motion and foot-strike mechanism that enhances speed by elevating foot-ground impact forces. "The sprinters we tested all used the same mechanism for maximizing force application and sprinting performance," said the study's lead author.

Laser pulse turns glass into a metal: New effect could be used for ultra-fast logical switches Posted: 26 Aug 2014 07:08 AM PDT For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by new calculations. The effect could be used to build logical switches which are much faster than today's microelectronics.
