This new artificial skin can sense changes in pressure, heat, and cold. This artificial skin could lead to more advanced prosthetics and robots. (Image credit: RMIT University)   Though it’s unpleasant, pain is necessary because it helps keep us safe, warning us when our body is in discomfort. Now, researchers have created an artificial skin that can react to pain similar to real human skin. The prototype, created by a team at RMIT University in Melbourne, Australia, mimics the body& ...
To achieve the effect, researchers created a unique Hall-bar-like device of graphene-topological insulator heterostructures. Researchers believe this discovery could be used for applications in spintronic and quantum technologies. (Image credit: CC0 Public Domain)   The spin galvanic effect is a theory many have studied for years for its application to spintronics technology and potential use in the next generation of electronics. Recently, researchers at the Chalmers University of Technol ...
Are we one step closer to the holographic technology found in a galaxy far, far away? (Image credit: Tokyo University)   Remember the scene from Star Wars: A New Hope when Princess Leia used holographic technology to ask Obi-Wan Kenobi for help? That scene is now a reality thanks to a recent breakthrough. Researchers from the Tokyo University of Agriculture and Technology discovered a way to bend light in ways that natural materials can't - using metasurface materials. The result is a true ...
The nano=scaled tweezers could be used to detect pathogens and early stages of diseases such as Alzheimer's. (Image Credit: Justus Ndukaife, Vanderbilt University)   Today's optical tweezers, which use a highly focused laser beam to trap and move micron-scale objects, can't grip anything smaller than a red blood cell. Engineers at Vanderbilt University have developed opto-thermal-electrohydrodynamic tweezers (OTET) that are capable of manipulating DNA molecules and proteins without causing ...
Source: screenshot from neuralink.   In a live-stream broadcast via YouTube on August 28, Elon Musk demonstrated his startup Neuralink’s technology, which had been surgically implanted into the skull of a pig named Gertrude. The aim of this implant is to create a digital link between brains and computers. The demonstration showcased a computing link displaying the pig’s brain activity via a wireless link from the Neuralink.   The technology, which Musk says is close to r ...
Hayabusa2 deployed three rovers and a lander on the Ryugu asteroid, which collected samples of the asteroid's surface. The return mission has been officially approved to land in Australia on December 6th. (Image Credit: JAXA/Akihiro Ikeshita)   On August 19th, 2020, the Japan Aerospace Exploration Agency (JAXA) announced that its Hayabusa2 spacecraft had been approved to land in Australia on December 6th. The space cargo is returning to Earth while carrying sample material that was capture ...
The TI-125 is designed for measurement, detection, and sampling tasks for R&D and industrial functions, but can also be utilized for COVID-19 applications as well. (Image credit: Omega)   Omega designed its T-120 Series of thermal imaging cameras for research and development and industrial applications as a solution that can handle a myriad of measurement, sampling, and detection tasks over a wide area of operations. Compared to other thermal imaging systems on the market, the TI-120 Se ...
'This physical property can be used to make more precise measurements, which in turn can lead to advance technology like quantum computers. Quantum laser light shines on to a chemical molecule that needs to be measured. The light then passes through the quantum filter, which discards a lot of the light and condenses the useful information in a light that reached the camera. (Image credit: Hugo Lepage)   Scientists recently discovered a physical property, coined "quantum negativity," that c ...
The new system would be ideal for underwater data centers that need to connect with surface networks. The system uses various off-the-shelf components and a Raspberry Pi to act as a modem. (Image credit: KAUST)   With Wi-Fi readily available in our daily lives, it’s easy to take for granted how vital these connections are, especially underwater. Many underwater data centers depend on Wi-Fi to connect with the surface network infrastructure. But the strong signals required can be chal ...
The new method of tracking space junk involves using high-powered lasers that detect diffused reflections bouncing back from the debris orbiting up to 36,000 kilometers away. (Image credit: NASA)   There’s a good chance that no matter where you are on the planet, there will be a piece of garbage nearby. On the top of Mount Everest, deserted islands, the North and South Poles, even in the most desolate of places, there is always a piece of refuse not far away. The same is true in spac ...
Citizen-owned seismometers showed significant reductions of noise around schools and universities in places like Cornwall, UK and Boston, U.S.  (Image Credit: Imperial College London)   Seismometers measure seismic waves from earthquakes, volcanoes, and they can pick up vibrations from wind, rivers, ocean waves and human activities. An international team of researchers recently revealed that human-linked vibrations in the Earth dropped by an average of 50% between March and May 2020 d ...
Mutekimaru has already logged over 780 hours of Pokemon Ruby. (Image Credit: Mutekimaure Channel)   I’ve been a huge fan of fish ever since my “Project Goldie" internet controlled fishtank build here on element14. This is a pretty fun way of interfacing your fish to the world.   Who says fish can’t do anything other than swim around? A fish in Japan named Mutekimaur (aka Maurice) is playing the Pokemon Ruby video game. The fish’s progress is being tracked o ...
This image shows a monolayer WSe2 housing "composite fermions," a quasi-particle created from the interaction between electrons. It's also responsible for the sequence of fractional quantum Hall states. (Image Credit: Cory Dean/Columbia University) Researchers from Columbia University successfully examined a quantum fluid called the fractional quantum Hall states (FQHS) in a monolayer 2D semiconductor. The team's discovery shows the high intrinsic quality of 2D semiconductors and establishes t ...
The very first video call took place fifty years ago, which involved using the Picturephone Mod II device. (Image Credit: Chris Harrison/Carnegie Mellon University)   Fifty years ago, the first-ever video call took place using AT&T’s Picturephone Mod II between Peter Flaherty, then-Pittsburgh Mayor, and John Harper, former chairman of Alcoa. This was the first video phone that could be installed in your home or office, and when AT&T’s network went live on July 1, 1970, ...
A new prototype from UCLA can translate sign language using a smartphone with 98.63% accuracy. Unlike previous devices, this one is lightweight and inexpensive. (Image credit:  UCLA)   American Sign Language (ASL) is a difficult language to learn, but a new glove by UCLA could make things easier. Researchers have developed an inexpensive glove that translates sign language into written and spoken words on a smartphone.   The prototype is made up of a pair of gloves with thin, s ...
