Heartbeat-Powered Pacemaker

The idea proposed by reseachers at the University of Michigan is to harvest the energy released by a heartbeat to power the pacemaker regulating the same heart: Piezoelectric materials generate an electric charge when their shape is changed. They are used in some microphones to convert vibrations into an electrical signal. Researchers at the University of Michigan are trying to use the movement of the heart as a source of electricity. In tests designed to simulate a range of heartbeats, enough electricity was generated to power a pacemaker. The designers now want to test the device on a real heart and build it into a commercial pacemaker. Link -via Glenn Reynolds  | Photo: Heart Pencil Holder on sale at the NeatoShop

Don’t Call It a Dump Truck: This Massive Mineral Hauler Transforms Into an Overland Train

When massive, open-pit mines like the Minera Escondida —in Chile’s Atacama Desert—need to pull millions of tons of minerals out of the ground each year, they rely on fleets of huge, “Ultra-Class” haul trucks. The ETF Haul Train, however, pulls four times the minerals of these stone-toting behemoths with just one driver. More »

This spectacular proposed South Korean super-city will cost $275 billion

In an effort to boost its tourism industry, South Korea is considering a project that would see the construction of a $275 billion mega-city built on the islands of Yongyu-Muui in the port city of Incheon, next to Incheon International Airport. Called 8City, the attraction is expected to create 930,000 new jobs and attract 134 million tourists (mostly from China). But given the cost, it’s an open question as to whether it will ever get built. More »

Super-Earth Discovered In Stars' Habitable Zone

astroengine writes “The family of planets circling a relatively close dwarf star has grown to six, including a potential rocky world at least seven times more massive than Earth that is properly located for liquid water to exist on its surface, a condition believed to be necessary for life. Scientists added three new planets to three discovered in 2008 orbiting an orange star called HD 40307, which is roughly three-quarters as massive as the sun and located about 42 light-years away in the constellation Pictor. Of particular interest is the outermost planet, which is believed to fly around its parent star over 320 days, a distance that places it within HD 40307’s so-called “habitable zone.”” Read more of this story at Slashdot.

Scientists raise the alarm on human enhancement technologies

The Royal Society, along with the Academy of Medical Sciences, British Academy, and Royal Academy of Engineering, recently concluded a workshop called Human Enhancement and the Future of Work in which they considered the growing impact and potential risks of augmentation technologies. In their final report , the collaborative team of scientists and ethicists raised serious concerns about the burgeoning trend, and how humanity is moving from a model of therapy to one in which human capacities are greatly improved. The implications, they concluded, should be part of a much wider public discussion. More »

Apple Considering Switch Away From Intel For Macs

concealment sends this quote from Bloomberg: “Apple Inc. is exploring ways to replace Intel processors in its Mac personal computers with a version of the chip technology it uses in the iPhone and iPad, according to people familiar with the company’s research. Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005.” Read more of this story at Slashdot.
