Computer scientists from the University of Washington and the Allen Institute for Artificial Intelligence in Seattle have created an automated computer program that they claim “teaches everything there is to know about any visual concept.”
A 218-pound climber ascended and descended 25 feet of glass with no climbing equipment other than a pair of hand-held, gecko-inspired paddles (he also carried an additional 50-pound load in one trial).
A gecko is able to climb on glass by using… read more
A paralyzed person wearing a brain-controlled robotic exoskeleton is expected to make the first kick during the opening of the FIFA 2014 World Cup in Brazil on June 12.
The Walk Again Project is an international collaboration of more than 100 scientists, led by Prof. Miguel Nicolelis of Duke University and the International Institute for Neurosciences of Natal, Brazil.… read more

Researchers at three institutions have teamed up to develop new terahertz detectors based on carbon nanotubes that could lead to significant improvements in medical imaging, airport passenger screening, food inspection, and other applications.
The research at Sandia National Laboratories, Rice University and the Tokyo Institute of Technology is described in a paper in Nano Letters journal. The technique uses carbon nanotubes to detect… read more

Johns Hopkins researchers have created a miniature human retina in a dish that can sense light.
The work, reported online June 10 in the journal Nature Communications, “advances opportunities for vision-saving research and may ultimately lead to technologies that restore vision in people with retinal diseases,” says study leader M. Valeria Canto-Soler, Ph.D., an assistant professor of ophthalmology at the Johns Hopkins University School of Medicine.… read more

A Brigham and Women’s Hospital (BWH) team has created artificial blood vessels using a three-dimensional (3D) bioprinting technique.
The study is published online this month in Lab on a Chip.
“Engineers have made incredible strides in making complex artificial tissues such as those of the heart, liver and lungs,” said senior study author, Ali Khademhosseini, PhD, biomedical engineer, and director of the BWH Biomaterials… read more
Finnish and Italian researchers have developed a way to align molecular self-assemblies from nanometers to millimeters, an alternative to conventional top-down lithography approaches for creating electronic devices.
Molecular self-assembly, a concept derived from biology, leads to spontaneous organization of molecules into more complex and functional supramolecular structures.
Molecular self-assembly has been used for “templating” (using a pattern to cut or shape) functional devices, molecular… read more

Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have devised a technique that allows supramolecules (self-assembling nanoparticle arrays) to form a highly ordered thin film over macroscopic (large-scale) distances in one minute, instead of hours.
The supramolecules are based on block copolymers that were combined with gold nanoparticles to create nanocomposites. Under solvent annealing, these quickly self-assembled into hierarchically structured thin films spanning an area of several square… read more

University of Washington (UW) scientists have developed a new computational method for building new customized proteins that self-assemble (like biological systems) to revolutionize things like targeted delivery of drugs, vaccine development, and even electronic devices.
Invisibility cloaks can’t make objects fully invisible in all directions, colors, and polarizations, but Karlsruhe Institute of Technology (KIT) physicists have developed a workaround: an ideal invisibility cloak for diffusive light-scattering media, such as fog.
Their results are published in the journal Science.
In diffusive media, light is scattered by the particles in the medium. Examples are fog, clouds, or frosted glass panes that let the… read more
The Turing Test was passed for the first time by a chatbot called “Eugene Goostman” on Saturday by convincing 33% of the human judges that it was human, according to Professor Kevin Warwick, a Visiting Professor at the University of Reading and Deputy Vice-Chancellor for Research at Coventry University, in a statement.

Researchers at the University of California, Riverside have developed a new graphene-based nanoscale architecture that improves the performance of supercapacitors, a development that could mean faster acceleration in electric vehicles and longer battery life in portable electronics.
A supercapacitor is an energy storage device like a battery. The new design is based on ruthenium oxide anchored on a graphene foam electrode. It could deliver two times… read more

University of Central Florida researchers have invented a way to store energy in a copper wire by wrapping a supercapacitor* sheath around a core conductor wire, acting as a battery to power a connected device.
Applications could include electrical vehicles, space-launch vehicles, and portable electronic devices. By being able to store and conduct energy on the same wire, heavy, space-consuming batteries could become a thing of the… read more

A team of researchers at the University of Twente (Netherlands) and German University in Cairo has developed sperm-inspired microrobots that can be controlled by weak oscillating magnetic fields.
Described in a cover article in AIP Publishing’s journal Applied Physics Letters, the 322 micron-long robots consist of a head coated in a thick cobalt-nickel layer and an uncoated tail.
When the microrobot is subjected to an oscillating field of… read more

In addition, the new “semimetal” material exists in a sturdy 3D form that should be much easier to shape into electronic devices such as very fast transistors, sensors and transparent electrodes, the researchers say.
The results are described… read more
