New technology involving dots and wires adhering to live cells could some day provide early warnings for health problems Engineers have developed nanoscale tattoos-dots and wires that adhere to live cells-in a breakthrough that puts researchers one step closer to tracking the health of individual cells.

Researchers discover how to control the anomalous Hall effect and Berry curvature to create flexible quantum magnets for use in computers, robotics, and sensors. Some of our most important everyday items, like computers, medical equipment, stereos, generators, and more, work because of magnets. We know what happens when computers become more powerful, but what might be possible if magnets became more versatile?

In a ground-breaking experiment, scientists from the University of Groningen, together with colleagues from HFML-FELIX, University of Twente and the Harbin Institute of Technology (China), have discovered the existence of a superconductive state that was first predicted in 2017. In this week's edition of Nature, they present evidence for a special variant of the so-called FFLO superconducting state, a discovery that could have significant applications, particularly in the field of superconducting electronics.

Is it possible to 3D print biodegradable sensors and displays? Researchers from Empa's Cellulose & Wood Materials laboratory have developed a cellulose-based material that allows just that. The mixture of hydroxpropyl cellulose with water, carbon nanotubes and cellulose nanofibrils changes color when heated or stretched - without the addition of any pigments.

A new photonic radar system has been developed by scientists at Sydney Nano and the School of Physics that delivers contactless, high-definition detection of vital signs. It could be developed for use in ICUs, aged-care facilities and for people with sleep apnoea or infants with breathing concerns. Constant monitoring of vital health signs is needed in a variety of clinical environments such as intensive care units, for patients with critical health conditions, health monitoring in aged care facilities and prisons, or in safety monitoring situations where drowsiness can cause accidents.

Quantum computing could revolutionize our world. For specific and crucial tasks, it promises to be exponentially faster than the zero-or-one binary technology that underlies today's machines, from supercomputers in laboratories to smartphones in our pockets. But developing quantum computers hinges on building a stable network of qubits - or quantum bits - to store information, access it and perform computations.

Wildfires have become increasingly frequent due to climate change, with record occurrences in areas not historically prone to them. In California, wildfires and regional power shutoffs have cost billions and taken lives. For some 46 million Americans living next to forests - at what scientists call the "wildland-urban interface" (WUI) - the risks of wildfire can be especially acute.

A new Jell-O-like material could replace metals as electrical interfaces for pacemakers, cochlear implants, and other electronic implants. Do an image search for "electronic implants," and you'll draw up a wide assortment of devices, from traditional pacemakers and cochlear implants to more futuristic brain and retinal microchips aimed at augmenting vision, treating depression, and restoring mobility.

Scientists reveal that nonadiabatic tunneling is crucial for understanding high harmonic generation from semiconductors When matter is exposed to highly intense electromagnetic radiation, nonlinearities of the material may lead to the emission of light that contains very high multiples of the incident frequency.

By Birgit Baustädter Jurij Koruza and his team are working on electroceramics that are used in electronic devices. The team is part of a new and highly endowed collaborative research centre led by TU Darmstadt. Electroceramics are at the core of many electronic components. A mobile phone, for example, contains about 500 capacitors consisting of several layers of ceramic and metal.

Researchers from the University of Twente proved that germanene, a two-dimensional material made of germanium atoms, behaves as a topological insulator. It is the first 2D topological insulator that consists of a single element. It also has the unique ability to switch between 'on' and 'off' states, comparable to transistors.

Tiny tips on cantilevers are used to scan a surface in an atomic force microscope. A new invention from TU Wien now provides a simpler way to measure the result. The basic principle of the atomic force microscope is very simple: an extremely thin, movable tip on a cantilever is moved over a surface that is being examined.

The first comprehensive analysis of e-waste in Canada found electronic waste has tripled and is steadily growing New research finds that Canada's electrical and electronic waste (e-waste) has more than tripled in the last two decades, the equivalent of filling the CN tower 110 times and generating close to a million tons in 2020 alone.

The Technische Universität Ilmenau, together with research partners, has developed a microphone inspired by biology that picks up sound similar to the human ear. The microphone could help improve speech recognition for controlling a variety of digital applications. In the future, the new process could even make overall acoustic systems consisting of a microphone and speech recognition more efficient, so that they consume less energy.

May 3, 2023 New material converts vibrations into electricity  In a world hungry for clean energy, engineers have created a new material that converts the simple mechanical vibrations all around us into electricity to power sensors in everything from pacemakers to spacecraft. The first of its kind and the product of a decade of work by researchers at the University of Waterloo and the University of Toronto, the novel generating system is compact, reliable, low-cost and very, very green.

This doesn't happen often: For his final project, an electronics apprentice at ETH Zurich produced a test device that will save physicists a lot of time in developing a novel microscope. His work has been published in a scientific journal. Integrated into the research group Apprentices also have to prepare a detailed schedule for their IPA.

The device, which uses electricity to boost hormone production in the stomach, could help to ease nausea and counteract appetite loss. Hormones released by the stomach, such as ghrelin, play a key role in stimulating appetite. These hormones are produced by endocrine cells that are part of the enteric nervous system, which controls hunger, nausea, and feelings of fullness.

Thanks to a breakthrough in the field of magnonics, researchers have sent and stored data using charge-free magnetic waves, rather than traditional electron flows. The discovery could solve the dilemma of energy-hungry computing technology in the age of big data. Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption.

Tiny structures made of gold can be specifically manipulated by ion bombardment at TU Wien (Vienna) - surprisingly, the decisive factor is not the force of the impact. Normally, we have to make a choice in physics: Either we deal with big things - such as a metal plate and its material properties, or with tiny things - such as individual atoms.

An international team led by the University of Geneva has developed a quantum material in which the fabric of space inhabited by electrons can be curved on-demand. Artistic view. Curvature of the space fabric due to the superposition of spin and orbital states at the interface between lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3).
