Newly-developed earplug-sized air samplers are said to offer several advantages over tradi...

The monitoring of air quality can be a tricky business. Gases may be blown into the sampling site from another area, they may leak out of an air sample before it can be analyzed, or the sampling container itself may introduce compounds, emitted through off-gassing. If samples are being gathered in remote areas, it can also be difficult getting bulky equipment to and from the sampling site. Now, scientists from Sandia National Laboratories have announced a tiny new type of air sampler, that addresses these and other challenges.  Read More

In what is being touted as “the world's largest dream experiment,” a psychologist from Britain’s University of Hertfordshire is inviting volunteers to try using an iPhone app to control their dreams. Prof. Richard Wiseman teamed up with the developers at software company YUZA to create Dream:ON, an app that plays soundscapes while its user sleeps, intended to shape what sort of dreams they have. The project comes in response to a UK survey conducted by Wiseman, in which 15% of respondents claimed that they frequently suffered from unpleasant dreams.  Read More

Rattlesnakes, beware! The next time you spot a succulent-looking squirrel, it might actually be a cold-hearted robot. More specifically, it might be a “robosquirrel,” created by UC Davis professor of mechanical and aerospace engineering Sanjay Joshi. He built the robot squirrels as part of a study on rattlesnake behavior – a study which yielded some interesting results.  Read More

A graphene sensor effectively tattooed onto a tooth can be used to detect bacteria and so wirelessly monitor oral health, research has shown. Graphene printed onto water-soluble silk can be "bio-transferred" onto organic materials such as tooth enamel. By incorporating antimicrobial peptides and a resonant coil, individual bacteria cells can be detected without need of an onboard power supply or wired connections.  Read More

When completed in 2024, the Square Kilometre Array (SKA) will be the largest, most sensitive radio telescope ever created. It will consist of 3,000 individual ground-based dish antennas, linked to act as one big telescope – an arrangement known as an interferometer. While their combined total surface area will be about one square kilometer (0.39 sq mile), they will be spread out across a geographical area approximately 3,000 kilometers (1,864 miles) in width. They will be gathering about one exabyte of astronomical data per day, which is twice the amount of data that is handled by the World Wide Web on a daily basis. Today, IBM announced that it has partnered with ASTRON (the Netherlands Institute for Radio Astronomy), in an effort to develop computer systems that will be able read, analyze and store all of that data, and do so in an energy-efficient manner.  Read More

NASA's stunning Perpetual Ocean animation visualizes ocean currents (Image: NASA/Goddard S...

NASA’s Goddard Space Flight Center is an unlikely entrant in the SIGGRAPH Computer Animation Festival. Its “Perpetual World” animation may have failed to appeal to the judging committee of the 2011 edition of the competition, but it sure succeeded in catching our eye. The jaw-dropping animation visualizes the flow of surface ocean currents around the world. The raw data regarding the currents from June 2005 through to December 2007 has been turned into a work of art reminiscent of van Gogh.  Read More

Researchers at MIT and the University of Pittsburgh have successfully resuscitated non-oscillating Belousov-Zhabotinsky (BZ) gel by exerting a mechanical stimulus: a process akin to the resuscitation of a human heart. By exhibiting a chemical response to a mechanical stimulus (a rare feat for non-living matter), it's claimed the material could lead to the development of artificial skin that would enable robots to feel.  Read More

Sandia's Z-Accelerator in action (Photo: Sandia National Laboratories)

In the beginning, there was the thermonuclear bomb - mankind had harnessed the energy of the Sun. Confident predictions abounded that fusion reactors would be providing power "too cheap to meter" within ten years. Sixty years later many observers are beginning to wonder if billions of dollars of effort has been lost in digging out dry wells. Now a new simulation study carried out at Sandia National Laboratories in Albuquerque, New Mexico, suggests that magnetized inertial fusion (MIF) experiments could be retrofitted to existing pulsed-power facilities to obtain fusion break-even.  Read More

An experimental system allows a computer to determine whether or not a human speaker is ly...

If the movie 2001: A Space Odyssey taught us anything, it’s that computers know when we’re telling a lie. While that may not actually be the case for most computers in real life, it could be if they’re running a program created by scientists from the University at Buffalo. Building on a previous psychological study, the team produced software that allowed a computer to assess a speaker’s eye movements, to determine whether or not they were telling the truth in a prerecorded conversation. It turns out that the computer was able to correctly able to spot their lies with 82.5% accuracy. According to the researchers, a trained human interrogator only manages a success rate of about 65%.  Read More

The buckliball (left) and the toy that inspired its creation

Taking inspiration from a toy, a team of researchers at MIT have developed a new engineering structure that is mechanically unstable, yet collapses in a way that is predictable and reversible. The structure, formed out of a single piece of rubber-like material, is fabricated so that it collapses in harmony to form a smaller structure that can then be expanded into the original shape. This structure opens up new potentials in everything from architecture to micro-medical applications.  Read More
