A team of researchers at Stanford University has developed a theoretical way to cool down heated objects. [24]
When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]
An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22]
The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape.

At the Department for Materials of the ETH in Zurich, Pietro Gambardella and his collaborators investigate prospective memory devices. [32]
UCLA biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. [31]
Scientists at the Wellcome Trust/ Cancer Research UK Gurdon Institute, University of Cambridge, have identified a new type of stem cell in the brain which they say has a high potential for repair following brain injury or disease. [30]
A team of researchers working at the Weizmann Institute of Science has found that organoids can be used to better understand how the human brain wrinkles as it develops. [29]

Researchers working on an Army project developed nanoscale thermal switches that are key to thermal management of nanoscale devices, refrigeration, data storage, thermal computing and heat management of buildings. [32] The precision of measuring nanoscopic structures could be substantially improved, thanks to research involving the University of Warwick and QuantIC researchers at the University of Glasgow and Heriot Watt University into optical sensing. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29] Magnetic materials that form helical structures-coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule-occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors-sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields. [27] At Carnegie Mellon University, Materials Science and Engineering Professor Mike McHenry and his research group are developing metal amorphous nanocomposite materials (MANC), or magnetic materials whose nanocrystals have been grown out of an amorphous matrix to create a two phase magnetic material that exploits both the attractive magnetic inductions of the nanocrystals and the large electrical resistance of a metallic glass. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25]

Researchers have made a breakthrough in the control of terahertz quantum cascade lasers, which could lead to the transmission of data at the rate of 100 gigabits per second-around one thousand times quicker than a fast Ethernet operating at 100 megabits a second. [58] Prospective digital data storage devices predominantly rely on novel fundamental magnetic phenomena. [57] Scientists at Linköping University have shown how a quantum computer really works and have managed to simulate quantum computer properties in a classical computer. [56] Scientists from the University of Bath, working with a colleague at the Bulgarian Academy of Sciences, have devised an ingenious method of controlling the vapour by coating the interior of containers with nanoscopic gold particles 300,000 times smaller than a pinhead. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation. [52] Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory. [51]
