Scientists have already created mini-cyborgs out of living cells and semiconductor materials, but now biological cells can also contain tiny silicon chips. Those silicon chips could become future intracellular sensors that monitor microscopic activities, deliver drugs to target cells or even repair cell structures, according to Nanowerk.
Skyborne chemical lasers have successfully shown off their potential killing power, and so the Air Force has now turned toward putting a more compact electric laser aboard its aircraft, Aviation Week'sAres Defense Blog reports.
Hangar One's behemoth structure once housed airships such as the doomed U.S.S. Macon, and is so large that clouds can supposedly form and rain inside it. Now NASA and the U.S. Navy have promised to replace the hangar's toxic siding with a new Teflon-covered fiberglass fabric skin, The Register reports.
Cambodian children grow up in a nation where millions of landmines left by decades of civil war have continued to cripple and kill hundreds of people each year. Now they could get a life-saving lesson from a video game developed by Michigan State University researchers.
In the game, players navigate photos of Cambodian jungle landscapes in search of photos for several adorable cartoon pets -- no cartoon landmine characters here. The point of the maze-like game is to train players and embed warning signals about landmines in their minds.
Mating a rocket with a helicopter sounds improbable, but only until you watch the Dragonfly DF1 take to the skies. DVICE reports that the rocket-powered copter received airworthiness certificates last November, and may go on sale as early as this year.
The copter makes use of tiny hydrogen-peroxide-powered rocket motors on the tips of the blades, which replaces the traditional engine-powered rotor. Large fuel tanks surrounding the pilot allow the Dragonfly to travel at up to 40 mph for 50 minutes.
Lithium-ion batteries used in hybrid cars, laptops and cell phones have occasionally undergone recalls and false scares concerning the possibility of exploding. Stanford University scientists have created lithium-sulfide electrodes that could create batteries that last four times longer and avoid any risk of possible explosions, Technology Review reports.
Springtime on Mars means the thaw of carbon dioxide ice in the northern hemisphere. And when the dry ice goes, the party's over for any trapped debris that then goes tumbling down Martian cliffs in spectacular images such as this.
Human skin is apparently a very energy-efficient conduit for transmitting data. A recent experiment achieved a rate of 10 megabits per second, which may put my Internet connection to shame. The experiment used small, flexible electrodes and took place at Korea University in Seoul, New Scientist reports.
Solar storms could wreak havoc on satellites and power grids, and so scientists have humbly turned to netizens across the world to help watch our sun for possible signs of such storms. Anyone who can spare some time from YouTube and Facebook also gets to peer at nifty 3-D images of the sun, according to BBC.
Piezoelectric materials that create energy when flexed might go beyond recharging our smart phones and help make hydrogen fuel. Scientists have harnessed piezoelectric energy from nanocrystal fibers to split water into oxygen and hydrogen gas.
"This is a new phenomenon, converting mechanical energy directly to chemical energy," said Huifang Xu, a geologist at the University of Wisconsin-Madison. He and his colleagues have dubbed it the piezoelectrochemical (PZEC) effect.
