A new way of transmitting electricity wirelessly has been discovered by U.S. researchers. It could pave the way for the wireless charging of portable electronic devices, rendering power cords obsolete in the process.
Devised by physicists at the Massachusetts Institute of Technology (MIT), in Boston, the new technology is detailed today in the U.S. journal Science.
At the turn of the 20th century, famed physicist and inventor Nikola Tesla devoted considerable effort towards achieving large scale wireless power transfer. Success proved elusive, however, and the demand for such schemes declined.
Now, the revolution in consumer technology has re-ignited the interest of researchers.

Yes, this summer Billy and the Good Doctor are going to be traipsing through the upper Amazon as part of an Anthropological research team studying TB. Needless to say, posts will be few and far between. If any of our minor contributors would like to step up and take over, it would be much appreciated. Also, if any of our readers would like to become posters, just drop us an email (on the ‘about’ page) and we will work with you. Much love to you all and thanks for supporting us. Ciaofor now.
Dutch researchers are trying to grow pork meat in a laboratory with the goal of feeding millions without the need to raise and slaughter animals.
“We’re trying to make meat without having to kill animals,” Bernard Roelen, a veterinary science professor at Utrecht University, said in an interview.
Although it is in its early stages, the idea is to replace harvesting meat from livestock with a process that eliminates the need for animal feed, transport, land use and the methane expelled by animals, which all hurt the environment, he said.
“Keeping animals just to eat them is in fact not so good for the environment,” said Roelen. “Animals need to grow, and animals produce many things that you do not eat.”

An Australian firm has developed a renewable tidal energy conversion system based on the highly efficient fin structure of shark, tuna, and mackerel.
BioPower Systems Pty Ltd., a renewable energy systems company based in Eveleigh, New South Wales, says that its bioSTREAM technology for converting tidal and marine current energy into electricity is modeled on biological species, such as shark and tuna, that use Thunniform-mode swimming propulsion.
“The motions, mechanisms, and caudal fin hydrofoil shapes of such species have been optimized by natural selection and are known to be up to 90% efficient at converting body energy into propulsive force,” said BioPower Systems in a media release. “The bioSTREAMâ„¢ mimics the shape and motion characteristics of these species but is a fixed device in a moving stream… By mimicking these creatures, the bioSTREAM benefits from 3.8 billion years of evolutionary hydrodynamic optimization. The inherited biological traits result in a cost effective and reliable renewable energy system.”
