The miniaturization of microelectronic sensor technology, microelectronic robots or intravascular implants is progressing rapidly. However, it also poses major challenges for research. One of the biggest is the development of tiny but efficient energy storage devices that enable the operation of autonomously working microsystems -- in more and more smaller areas of the human … [Read more...] about Smallest biosupercapacitor provides energy for biomedical applications

Researchers have developed a mathematical model that can predict the optimum exercise regime for building muscle. The researchers, from the University of Cambridge, used methods of theoretical biophysics to construct the model, which can tell how much a specific amount of exertion will cause a muscle to grow and how long it will take. The model could form the basis of a … [Read more...] about Mathematical model predicts best way to build muscle

Scientists from SANKEN at Osaka University demonstrated the readout of spin-polarized multielectron states composed of three or four electrons on a semiconductor quantum dot. By making use of the spin filtering caused by the quantum Hall effect, the researchers were able to improve upon previous methods that could only easily resolve two electrons. This work may lead to quantum … [Read more...] about Accessing high-spins in an artificial atom

Artificial intelligence (AI) will fundamentally change medicine and healthcare: Diagnostic patient data, e.g. from ECG, EEG or X-ray images, can be analyzed with the help of machine learning, so that diseases can be detected at a very early stage based on subtle changes. However, implanting AI within the human body is still a major technical challenge. TU Dresden scientists at … [Read more...] about Using artificial intelligence for early detection and treatment of illnesses

In a step toward a future of higher performance memory devices, researchers from National Taiwan Normal University and Kyushu University have developed a new device that needs only a single semiconductor known as perovskite to simultaneously store and visually transmit data. By integrating a light-emitting electrochemical cell with a resistive random-access memory that are both … [Read more...] about One material with two functions could lead to faster memory: Researchers use perovskite to develop a memory device readable through both electrical and optical methods

The quantum computing market is projected to reach $65 billion by 2030, a hot topic for investors and scientists alike because of its potential to solve incomprehensibly complex problems. Drug discovery is one example. To understand drug interactions, a pharmaceutical company might want to simulate the interaction of two molecules. The challenge is that each molecule is … [Read more...] about Opening a path toward quantum computing in real-world conditions: Quantum computing platform accelerates transition from bulk optics to integrated photonics on a silicon chip smaller than a penny

Sea cucumbers have a bumpy and oblong shape. They are soft but stiffen up quickly when touched. They can shrink or stretch to several meters, and their original shape can be recovered even after they die and shrivel up with the regulation of water uptake. Recently, a POSTECH research team has developed a soft actuator inspired by this unique behavior of sea cucumbers. A … [Read more...] about Water-driven soft actuator developed

A new study published in Physical Review Letters describes a way to increase the cargo capacity of microscopic, self-propelled droplets known as "microswimmers." Researchers from the University of Pennsylvania and the Max Planck Institutefor Dynamics and Self-Organisation found that when a school of microswimmers move in the same direction inside a narrow channel, they can … [Read more...] about How schools of ‘microswimmers’ can increase their cargo capacity

A novel artificial intelligence blood testing technology developed by researchers at the Johns Hopkins Kimmel Cancer Center was found to detect over 90% of lung cancers in samples from nearly 800 individuals with and without cancer. The test approach, called DELFI (DNA evaluation of fragments for early interception), spots unique patterns in the fragmentation of DNA shed from … [Read more...] about Novel AI blood testing technology can ID lung cancers with high accuracy

Be it nuclear power plants, patient monitoring equipment in hospitals, or self-driving cars -- integrations of physical processes with computers and process control, or cyber-physical systems (CPS), are everywhere. However, the widespread application of CPS also makes them prime targets for hackers. A simple change in the value of a sensor can create havoc. Vulnerability to … [Read more...] about Novel resilient state estimation method for process control in cyber-physical systems: Scientists create a new process control model to protect systems from assailants and natural fluctuations
