Instant-Start Computers With New Breakthrough

Instant-Start Computers With New Breakthrough

To encode data, today’s computer memory technology uses electric currents — a major limiting factor for reliability and shrinkability, and the source of significant power consumption. If data could instead be encoded without current — for example, by an electric field applied across an insulator — it would require much less energy, and make things [...]

Lens-Free Microscope Detects Cancer at Cell Level

Lens-Free Microscope Detects Cancer at Cell Level

UCLA researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes.   The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens. [...]

Thumbs-Up for Mind-Controlled Robotic Arm

Thumbs-Up for Mind-Controlled Robotic Arm

A paralysed woman who controlled a robotic arm using just her thoughts has taken another step towards restoring her natural movements by controlling the arm with a range of complex hand movements.   Thanks to researchers at the University of Pittsburgh, Jan Scheuermann, who has longstanding quadriplegia and has been taking part in the study [...]

Scientists Measure Speedy Electrons in Silicon

Scientists Measure Speedy Electrons in Silicon

The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our age.   An international team of physicists and chemists based [...]

‘Electronic Skin’ Accurately Detects Pressure

‘Electronic Skin’ Accurately Detects Pressure

Touch can be a subtle sense, but it communicates quickly whether something in our hands is slipping, for example, so we can tighten our grip. For the first time, scientists report the development of a stretchable “electronic skin” closely modeled after our own that can detect not just pressure, but also what direction it’s coming [...]

Composite Materials can be Designed in a Supercomputer ‘Virtual Lab’

Composite Materials can be Designed in a Supercomputer ‘Virtual Lab’

UCL scientists have shown how advanced computer simulations can be used to design new composite materials. Nanocomposites, which are widely used in industry, are revolutionary materials in which microscopic particles are dispersed through plastics. But their development until now has been largely by trial and error.   The ‘virtual lab’ developed using supercomputer simulations greatly [...]

Using Robots to Get More Food from Raw Materials

Using Robots to Get More Food from Raw Materials

Can an industrial robot succeed both at removing the breast fillet from a chicken, and at the same time get more out of the raw materials? This is one of the questions to which researchers working on the CYCLE project now have the answer.   They have built a fully-functional robot in the lab to [...]

Citizens’ Computers to Seek Ebola Cure

Citizens’ Computers to Seek Ebola Cure

Although some medical therapies show promise as treatments for Ebola, scientists are still looking urgently for a definitive cure.   For the first time, anyone with access to a computer or Android-based mobile device can help scientists perform this critical research — no financial contribution, passport or PhD necessary. In fact, volunteers can be asleep, [...]

Robot Control Theory Improves Prosthetic Legs

Robot Control Theory Improves Prosthetic Legs

A University of Texas at Dallas professor applied robot control theory to enable powered prosthetics to dynamically respond to the wearer’s environment and help amputees walk.   In research available online and in an upcoming print issue of IEEE Transactions on Robotics, wearers of the robotic leg could walk on a moving treadmill almost as [...]

Invisible 3D Shape That Can Be Seen, Felt

Invisible 3D Shape That Can Be Seen, Felt

Technology has changed rapidly over the last few years with touch feedback, known as haptics, being used in entertainment, rehabilitation and even surgical training. New research, using ultrasound, has developed an invisible 3D haptic shape that can be seen and felt.   The research paper, published in the current issue of ACM Transactions on Graphics [...]
