Spiky Hedgehog robots to hop around asteroids and comets

As demonstrated by the bumpy landing of ESA's Philae lander on comet 67P/Churyumov–Gerasimenko, exploring comets, asteroids, and small moons can be difficult due to their low gravity. Not only can landing on one be like trying to alight on a trampoline, but roving around their surfaces is next to impossible because the negligible gravity offers practically no traction. To overcome this, a team of engineers is developing Hedgehog, a completely symmetrical robot rover for low-gravity exploration that moves by hopping.Read More

Compostable electronics could ease the e-waste problem

Some day soon your obsolete gadgets could be as compostable as banana peels and spent coffee grounds. Researchers from the Young Investigator Network at Karlsruhe Institute for Technology (KIT) in Germany are developing printed electronics from natural and compostable materials that could help make a dent in the millions of tons of electronic waste piling up worldwide each year.Read More

One year Mars mission simulation underway in Hawaii

Six people have begun a year-long mission to Mars without ever leaving Earth. Last week on the slopes of Mauna Loa volcano in Hawaii, the volunteers sealed themselves inside a dome habitat where they will live in isolation for one year on a simulated space mission. The fourth Hawaii Space Exploration Analog and Simulation (HI-SEAS 4) aims to study how deep space missions can maintain morale on prolonged voyages.Read More

Wacom Bamboo Spark creates digital copies of written notes – no special paper required

If you want a smartpen – which digitizes your handwriting and transmits it to a computer or mobile device – you currently have your choice of models including the Neo Smartpen N2, the LiveScribe Sky or the Orée Stylograph. All of those pens, however, require you to use special paper that's unique to that particular product. By contrast, Wacom's just-announced Bamboo Spark system works with a non-electronic pen and whatever A5-sized paper you've got on hand.Read More

Completely paralyzed man steps out in robotic exoskeleton

Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps. Using a non-invasive spinal stimulation system that requires no surgery, this is claimed to be the first time that a person with such a comprehensive disability has been able to actively and voluntarily walk with such a device.Read More

Self-healing bioplastic – just add water

Imagine if things like undersea cables or medical implants could simply heal themselves back together if severed – it would certainly be easier than having to go in and fix them. Well, scientists at Pennsylvania State University are bringing such a possibility closer to reality. They've created a moldable polymer that heals itself when exposed to water – and it's based on squid sucker ring teeth.Read More

Ultra low-power wireless communication through the human body using magnetic fields

Be it on the inside or the outside, the human body is becoming host to an ever-increasing array of electronic devices that need to wirelessly communicate with each other. Now engineers working at the University of California, San Diego (UCSD) have come up with a different type of wireless communication that sends ultra low-power magnetic fields through the human body. This makes it extraordinarily more energy efficient and secure from prying eyes than comparable wireless communication technologies.Read More
