Curiosity finishes self-inspection, photographs Phobos

By - September 16, 2012 21 Pictures
NASA’s Mars rover Curiosity has limbered up its robotic arm, taken a good look at itself and has been given a clean bill of health. It’s now on the move as it starts its two-year mission of discovery on the Red Planet. On Thursday, it traveled 105 feet (32 m) as it seeks out its first rock for serious investigation. Meanwhile, the nuclear-powered explorer sent back images of Mars’s moon Phobos as it passed in front of the Sun. Read More

World's shortest laser pulse to shed new light on quantum mechanics

By - September 15, 2012 6 Pictures
Since first invented, the effort to make lasers that can produce shorter and more powerful pulses of light has been a very active one. One driving force is that if you want to take a picture of something occurring very rapidly, you need a very short pulse of light to prevent the image from blurring. The first ruby laser produced microsecond pulses of light, but more recently femtosecond optical pulses a billion times shorter have become common. Still shorter pulses belong to the attosecond regime - the regime wherein a University of Central Florida research team is creating optical pulses sufficiently brief to stop quantum mechanics in its tracks.

Computer program is able to match rough sketches to real objects

By - September 14, 2012 3 Pictures
Currently, using Google’s “Search by Image” function, it’s possible to search the internet for information on something if you already have an image of that thing. Also, researchers at Carnegie Mellon University are developing a system that allows computers to match up users’ drawings of objects with photographs of those same items – the drawings have to be reasonably good, though. Now, however, a team from Rhode Island’s Brown University and the Technical University of Berlin have created software that analyzes users’ crude, cartoony sketches, and figures out what it is that they’re trying to draw.

Laser-based system promises to take the "ouch" out of injections

By - September 14, 2012 3 Pictures
Nobody likes getting their shots, but whether childhood immunization, annual flu vaccination, or whatever else, we're required to undergo the uncomfortable sensation of needle piercing skin multiple times throughout our lives. However, a new laser-based system promises to take the “ouch” out of injections by delivering shots as painlessly as being struck by a puff of air. Read More

Chorus: The digital assistant powered by people, not computers

Computer scientists are looking to improve on the performance of artificially intelligent personal assistants by devising a way to use the power of a human crowd to chat you instead. The system, known as Chorus, was designed by researchers at the University of Rochester to allow a number of users to act as a single agent that converses with a single end user in real time.

Superhydrophobic coating allows water to boil without bubbles

By - September 14, 2012 1 Picture
You know that thing that water does when it boils? The thing with the bubbles? Turns out, it doesn't really need to do that at all, with scientists finding a way to make boiling water a completely bubble-free zone. Researchers from Northwestern University, King Abdullah University of Science and Technology in Saudi Arabia and Melbourne University in Australia teamed up to prevent water from bubbling when it boils by using tiny spheres coated with a hydrophobic material.

Ancient Egyptian faience may be key to printing 3D ceramics

By - September 12, 2012 2 Pictures
We like to think of technology as always being forward looking. It’s supposed to be about nanoparticles and the Cloud, not steam engines and the telephone exchange. But every now and again the past reaches out, taps the 21st century on the shoulder and says, “Have a look at this.” That’s what happened to Professor Stephen Hoskins, Director of the University of West England, Bristol's Centre for Fine Print Research. He is currently working on a way of printing 3D ceramics that are self-glazing, thanks to a 7,000-year old technology from ancient Egypt. Read More

New software turns sleep patterns into music

A group of computer scientists based at the University of Helsinki, Finland, have developed new software which creates automatically composed music from data concerning a person's sleep measurements. The software makes use of figures gleaned from an internet-equipped Beddit sensor, which is placed beneath a subject's mattress in order to record the stages of their sleep, their movements, heart rate and breathing.

Synthetic materials set new world record for greatest amount of surface area

By - September 11, 2012 1 Picture
Researchers at Northwestern University, Illinois, have broken a world record in the creation of two synthetic materials, named NU-109 and NU-110, which have the greatest amount of surface areas of any material to date. To put this into perspective: if one were able to take a crystal of NU-110 the size of a grain of salt, and somehow unfold it, the surface area would cover a desktop. Additionally, the internal surface area of just one gram of the new material would cover one-and-a-half football fields. Read More
