At MIT, the graduate students live by the following adage: “coursework, research, sleep – pick two.” I toiled under that mantra for six years, believing things could not possibly get worse. Silly me, I traded grad school for an assistant professor job where the governing adage is “research, grant writing, teaching, service – pick two, but excel at them all.” Note that in this job, sleep doesn’t even make the list.
However, even as CGIAR and IFPRI are calling for reductions in biofuel production from food crops, President Bush is pushing for increased domestic ethanol generation from corn. According to the AP article, “Food scientists say stop biofuels to fight world hunger,” the President’s push to increase biofuel production arises from his national energy security policy and a desire to mitigate record-high fuel prices.
So, what do we do? We can starve our neighbors (and ourselves), save the environment, or secure our national energy supply; but we can’t do them all. The classic conundrum of having too many necessities and not enough resources to devote has escalated into a global problem: fuel, food, security - pick two.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
