Electronic components join forces to take up 10 times less space on computer chips
Electronic filters are essential to the inner workings of our phones and other wireless devices. They eliminate or enhance specific input signals to achieve the desired output signals. They are essential, but take up space on the chips that researchers are on a constant quest to make smaller. A new study demonstrates the successful integration of the individual elements that make up electronic filters onto a single component, significantly reducing the amount of space taken up by the device.
Grasshopper jumping on Bloch sphere finds new quantum insights
New research has (pardon the pun) put a new spin on a mathematical analogy involving a jumping grasshopper and its ideal lawn shape. This work could help us understand the spin states of quantum-entangled particles.
Materials science researchers develop first electrically injected laser
Materials science researchers have demonstrated the first electrically injected laser made with germanium tin. Used as a semiconducting material for circuits on electronic devices, the diode laser could improve micro-processing speed and efficiency at much lower costs.
Smartphones prove to be time-saving analytical tools
Scientists use a smartphone camera to easily measure soil density -- a key metric for analyzing our soils.
Break it down: A new way to address common computing problem
A new algorithm provides a framework for solving complex linear inverse problems that doesn't require a supercomputer and also enhances security and privacy.
How thoughts could one day control electronic prostheses, wirelessly
The current generation of neural implants record enormous amounts of neural activity, then transmit these brain signals through wires to a computer. But, so far, when researchers have tried to create wireless brain-computer interfaces to do this, it took so much power to transmit the data that the implants generated too much heat to be safe for the patient. A new study suggests how to solve his problem -- and thus cut the wires.
Recovering data: Neural network model finds small objects in dense images
In efforts to automatically capture important data from scientific papers, computer scientists have developed a method that can accurately detect small, geometric objects such as triangles within dense, low-quality plots contained in image data. Employing a neural network approach designed to detect patterns, the model has many possible applications in modern life.
Consumers don't fully trust smart home technologies
Smart home technologies are marketed to enhance your home and make life easier. However, consumers are not convinced that they can trust the privacy and security of these technologies, a new study has shown.
'Deepfakes' ranked as most serious AI crime threat
Fake audio or video content has been ranked by experts as the most worrying use of artificial intelligence in terms of its potential applications for crime or terrorism, according to a new report.
Novel magnetic stirrer speaks to lab equipment
A small device, called 'Smart Stirrer', performed a function of a conventional laboratory stir bar, has an integrated microprocessor and various sensors capable of wireless and autonomous report the conversion of properties of a solution. Results are sent to a computer over Bluetooth, and any changes notify the user wirelessly.
Re-engineering antibodies for COVID-19
A researcher is using 'in silico' analysis to fast-track passive immunity.
When Dirac meets frustrated magnetism
Scientists have discovered one of the largest anomalous Hall effects (15,506 siemens per centimeter at 2 Kelvin) ever observed in the new compound, KV3Sb5. This material has a never-before-seen combination of properties: Dirac physics, frustrated magnetism, 2D exfoliatability, and chemical stability. Aside from future fundamental research studying the interplay of these ingredients, the unique combination has potential for next-generation computing technologies like spintronics and quantum computing.
How human sperm really swim: New research challenges centuries-old assumption
A breakthrough in fertility science has shattered the universally accepted view of how sperm 'swim'.
Simulating quantum 'time travel' disproves butterfly effect in quantum realm
Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no 'butterfly effect.' In the research, information--qubits, or quantum bits--'time travel' into the simulated past.
Using artificial intelligence to smell the roses
A pair of researchers has used machine learning to understand what a chemical smells like -- a research breakthrough with potential applications in the food flavor and fragrance industries.
