Metal wires of carbon complete toolbox for carbon-based computers
Transistors based on carbon rather than silicon could potentially boost computers' speed and cut their power consumption more than a thousandfold-think of a mobile phone that holds its charge for months-but the set of tools needed to build working carbon circuits has remained incomplete until now.
This tiny device can scavenge wind energy from the breeze you make when you walk
Most of the wind available on land is too gentle to push commercial wind turbine blades, but now researchers in China have designed a kind of "tiny wind turbine" that can scavenge wind energy from breezes as little as those created by a brisk walk.
Sensors of world's largest digital camera snap first 3,200-megapixel images at SLAC
Crews at the Department of Energy's SLAC National Accelerator Laboratory have taken the first 3,200-megapixel digital photos-the largest ever taken in a single shot-with an extraordinary array of imaging sensors that will become the heart and soul of the future camera of Vera C. Rubin Observatory.
Artificial Iris Inside Smart Contacts Corrects Vision Disorders
The pupil of the eye allows light to reach the retina, and a number of vision disorders are related to irregularities in the iris that surrounds the pupil. People with aniridia, for example, have some or all of the iris missing, exhibiting a large pupil that results in unfocused vision.
A quantum-inspired framework for video sentiment analysis
Automatically identifying the overall sentiment expressed in a video or text could be useful for a wide range of applications. For instance, it could help companies or political parties to screen large amounts of online content and gain insight on what the public thinks about their products, services, campaigns or initiatives.
New electronic skin can react to pain like human skin
As well as the pain-sensing prototype, the research team has also developed devices made with stretchable electronics that can sense and respond to changes in temperature and pressure. Bhaskaran, co-leader of the Functional Materials and Microsystems group at RMIT, said the three functional prototypes were designed to deliver key features of the skin's sensing capability in electronic form.
A collection of science & technology news that I found interesting this month. Since this is the first of these posts, I have some catching up to do, so there are older links as well. Many of these relate to tech that’s covered in “Machinehood,” as well as other stories, but some are here purely for inspiration.
Nanoparticle-based computing architecture for nanoparticle neural networks
Scalable nanoparticle-based computing architectures have several limitations that can severely compromise the use of nanoparticles to manipulate and process information through molecular computing schemes. The von Neumann architecture (VNA) underlies the operations of multiple arbitrary molecular logic operations in a single chip without rewiring the device.
Japan's 'flying car' gets off ground, with a person aboard (Video)
The decades-old dream of zipping around in the sky as simply as driving on highways may be becoming less illusory. Japan's SkyDrive Inc., among the myriads of "flying car" projects around the world, has carried out a successful though modest test flight with one person aboard.
Origami Surgical Manipulator to Perform Microsurgeries |
Robotic surgical assistants, such as the da Vinci systems from Intuitive Surgical, are now routinely used during laparoscopic procedures to improve operative precision, flexibility, and to manipulate multiple tools at once. Such devices can be quite complex inside and so they tend to be quite large, often taking up much of the space of an operating room.
Bacteria could survive travel between Earth and Mars when forming aggregates
Imagine microscopic life-forms, such as bacteria, transported through space, and landing on another planet. The bacteria finding suitable conditions for its survival could then start multiplying again, sparking life at the other side of the universe. This theory, called "panspermia", support the possibility that microbes may migrate between planets and distribute life in the universe.
Nanoengineered biosensors for early disease detection
University of Queensland researchers have developed biosensors that use nanoengineered porous gold which more effectively detect early signs of disease, improving patient outcomes. Most diagnostic methods use costly materials and are time-consuming and expensive to run, but Ph.D.
