Published Holographic message encoded in simple plastic
(via sciencedaily.com) Original source Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to produce a panel from normal plastic in which a QR code can be stored, for example. The message is read using terahertz rays -- electromagnetic radiation that is invisible to the human eye.
Published New technique helps AI tell when humans are lying
(via sciencedaily.com) Original source Researchers have developed a new training tool to help artificial intelligence (AI) programs better account for the fact that humans don't always tell the truth when providing personal information. The new tool was developed for use in contexts when humans have an economic incentive to lie, such as applying for a mortgage or trying to lower their insurance premiums.
Published Advanced army robots more likely to be blamed for deaths
(via sciencedaily.com) Original source Advanced killer robots are more likely to blamed for civilian deaths than military machines, new research has revealed. The study shows that high-tech bots will be held more responsible for fatalities in identical incidents.
Published Robot ANYmal can do parkour and walk across rubble
(via sciencedaily.com) Original source The quadrupedal robot ANYmal went back to school and has learned a lot. Researchers used machine learning to teach it new skills: the robot can now climb over obstacles and successfully negotiate pitfalls.
Published Scientists use novel technique to create new energy-efficient microelectronic device
(via sciencedaily.com) Original source Researchers have created a new material that uses 'redox gating' to control the movement of electrons in and out of a semiconducting material.
Published New AI technology enables 3D capture and editing of real-life objects
(via sciencedaily.com) Original source Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.
Published You don't need glue to hold these materials together -- just electricity
(via sciencedaily.com) Original source Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electro-adhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies.
Published Staying in the loop: How superconductors are helping computers 'remember'
(via sciencedaily.com) Original source To advance neuromorphic computing, some researchers are looking at analog improvements -- advancing not just software, but hardware too. Research shows a promising new way to store and transmit information using disordered superconducting loops.
Published Satellites for quantum communications
(via sciencedaily.com) Original source Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.
Published Powerful new tool ushers in new era of quantum materials research
(via sciencedaily.com) Original source Research in quantum materials is paving the way for groundbreaking discoveries and is poised to drive technological advancements that will redefine the landscapes of industries like mining, energy, transportation, and medtech. A technique called time- and angle-resolved photoemission spectroscopy (TR-ARPES) has emerged as a powerful tool, allowing researchers to explore the equilibrium and dynamical properties of quantum materials via light-matter interaction.
Published Cicadas' unique urination unlocks new understanding of fluid dynamics
(via sciencedaily.com) Original source While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.
Published Design rules and synthesis of quantum memory candidates
(via sciencedaily.com) Original source In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
Published AI-generated food images look tastier than real ones
(via sciencedaily.com) Original source Researchers have announced an intriguing discovery -- consumers generally prefer AI-generated images of food over real food images, especially when they are unaware of their true nature.
Published Researchers develop new machine learning method for modeling of chemical reactions
(via sciencedaily.com) Original source Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.
Published Making quantum bits fly
(via sciencedaily.com) Original source Physicists are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits 'fly'.
Published New method measures the 3D position of individual atoms
(via sciencedaily.com) Original source Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Shortcut to Success: Toward fast and robust quantum control through accelerating adiabatic passage
(via sciencedaily.com) Original source Researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity can be as high as 97.5% in GaAs quantum dots. This work may be useful to achieve fast and high-fidelity quantum computing.
