Lately, there has been growing interest in creating brain-inspired hardware for enhancing efficiency of AI models. Conventional hardware architectures are specialized in three specific tasks, which are: Researches across the globe, however, are exploring the possibility of combining these functionalities into a single device. They aim to mimic the parallel and distributed nature of the human brain.

Researchers at Stanford University have created a special kind of electronic skin that can sense things like heat and pressure and send signals to the brain. Electronic skin has been around for a while, but in the past, the devices used to convert these sensations into signals were bulky and inflexible. However, the new electronic skin is as soft and thin as real skin.

Radiotherapy is all about precision in targeting tumor tissue while minimizing damage to healthy tissue. To deliver precision radiation requires real time monitoring of the dose till the time it is absorbed. The task is quite challenging, especially if it is in gastrointestinal tract. The dynamic nature of the region makes it nearly inaccessible. Current approaches used for tracking biochemical indicators including pH and temperature are insufficient to give out comprehensive evaluation of radiotherapy.

Antineutrinos falls under the category of elusive particles. They are extremely difficult to detect due to their weak interaction with matter. These exotic particles have the same properties as neutrinos but with opposite charges. And have very little mass.

Certain materials like crystals, ceramics, and at times even biological matter (bone, DNA, and proteins), can generate an electrical charge. The effect is seen when the material is put under the influence of some mechanical stress – such as pressure or vibration – this phenomenon is termed as piezoelectricity. The charge is accumulated on the surface of the material. From there, it can be used for various applications.

Zinc batteries have been explored as an alternative to lithium-ion batteries for large-scale energy storage since long. Zinc-based batteries is preferred over li-ion batteries because it is abundant, low-cost, and environmentally friendly compared to other metals. However, their efficiency has been limited due to issues with the zinc metal anode. However, with the recent development of a new electrolyte that improves the efficiency of the zinc metal anode to nearly 100%, researchers envision that it could make zinc batteries a viable alternative.

Entanglement is a unique and powerful feature of quantum mechanics. It allows two or more particles, such as photons of light, to become correlated in such a way that the state of one particle is immediately determined by the state of the other particle, regardless of the distance between them. This phenomenon has been studied extensively in the field of quantum physics. It has important implications for the development of quantum technologies such as quantum cryptography and quantum computing.

The researchers at the University of Innsbruck and the Université Paris-Saclay have developed a method for linking multiple quantum systems by trapping atoms in optical cavities. And then transferring the quantum information to light particles which can then be sent through optical fibers. They have successfully entangled two trapped ions located more than a few meters apart for the first time.

Haptic systems are mainly designed to control virtual objects. Their efficacy is good, but when it comes to controllers, joysticks, and steering wheels, things look slightly bulky. And tangled wires is another task to deal with. Researchers at City University of Hong Kong have come up with a portable solution to enhance the tactile VR experience.

Evolutionary biological processes take time but what if we introduce microbial catalysis to the system? The phenomenon of how cyanobacteria obtain nutrients for its survival from rocks in Atacama Desert inspired an international team of collaborators from University of California and Johns Hopkins University to consider the microbes as tools that may help humans to develop colonies on the moon and Mars.

In the coming two decades, nanotechnology will surely touch the lives of nearly all people across globe. As technology progresses, we will experience next generation sensors embedded in all things that we use, including our clothes, kitchen and within ourselves. Yes, IoT is coming here to stay. So, the next question is what will be the efficient power source for these devices, especially the implantable sensors and drug-delivery systems? Researchers at MIT have paved a way for glucose powered medical implants. With their newly designed glucose fuel cell, they are…

Soft skin sensors are beginning to transform the health care industry. We can surely predict that within a decade, people will be wearing skin sensors to detect the blood glucose level, oxygen level and to track other different blood components which currently require an incision. Researchers at Tufts University have developed a tattoo-like sensor that glows when exposed to light. The degree of brightness depends on the level of oxygen in blood. Silk fibroin hydrogel The sensor is made up of silk fibroin hydrogel. Fibroin is an insoluble protein that…

To explore more exotic particles, Beijing Electron Positron Collider (BEPC), the particle-physics lab, is undertaking a major re-equipping. The work is expected to complete by 2024. Dubbed as BEPCII-U, the new version will not only triple the current collision rate but it’ll also extend the maximum collision energy to 5.6 GeV from the existing 2–5 GeV. With the plans underway for next-generation collider, China might head the world in high-energy physics research.
