Mosquitos and Body Odour, stem cell cloning and the Most Powerful Computer
New research shows mosquitos infected with malaria become more attracted to body odour. And how stem cell cloning could help to treat human diseases and disorders.
A study published this week has revealed that malaria alters the behaviour of its mosquito host. When infected with the disease, the mosquitos became much more attracted to human body odour. The results could help us understand how malaria is transmitted and how we can prevent the spread of the disease. 大象传媒 Science Reporter Rebecca Morelle explains.
Google, NASA and the Universities Space Research Association have opened a new lab at the Ames research centre, complete with a $15 million 鈥渜uantum鈥� computer. The 512-quibit 鈥渜uantum鈥� computer will be 3,600 times faster than a conventional computer, using a D-Wave Two processor that allows it to calculate a solution to mathematical problems in a fraction of a second. D-Wave Systems鈥� Chief Technical Officer Dr Geordie Rose attempts to explain the physics behind the world鈥檚 most powerful computer.
On Tuesday, the Sun spouted an intense, high-energy solar flare, sending billions of tonnes of particles into space. Although some solar flares can interfere with satellites and communications, the sunspot that spawned these flares were not directly facing Earth. In the build-up to the Sun鈥檚 peak in activity, sun flares might become more common.
