How do explanation methods for machine learning models work? Researchers have developed a method to verify that popular ways of understanding machine-learning models work correctly. Imagine a team comprising physicians who use a neural net to detect the presence of cancer in mammogram images. Even though the machine-learning model appears to be working well, it could focus […]

UNSW Sydney’s research has opened the door to large-scale silicon-based quantum processors that can be used in real-world manufacturing. Australian researchers have demonstrated that quantum computing is almost error-free. This opens the door to building silicon-based quantum devices compatible with all aspects of current semiconductor manufacturing technology. “Today’s publication Nature proves our operations were 99 percent error-free,” said Professor […]

Researchers have developed a way to allow workers to collaborate with artificial intelligence systems. A busy hospital radiologist uses an artificial intelligence system to diagnose medical conditions using patient X-ray images. The AI system can speed up her diagnosis, but how do you know when to trust its predictions? She doesn’t. She may instead rely […]

The official launch marks an important milestone in the European development of quantum computing. Forschungszentrum Julich has operated a quantum annealer that can process more than 5,000 qubits. Today, the Julich Supercomputing Centre and D-Wave Systems (a leader in quantum computing systems) launched the first cloud-based quantum service for customers outside North America. This new […]

According to quantum physics laws, a battery with a shorter recharge time than the stored energy was created by researchers at the Politecnico di Milano and the Institute of Photonics and Nanotechnologies of Cnr. Quantum batteries, a new type of energy storage device, operate on quantum physics principles. This science studies the infinitely small and […]

The new helmet-shaped wearable device monitors brain activity. Modern brain imaging techniques allow for high-resolution, precise observations of the brain’s functions. Functional near-infrared spectrum (fNIRS), a popular noninvasive imaging method, uses near-infrared (wavelength >700nm) light to determine the relative hemoglobin concentration in the brain. This is done by comparing hemoglobin’s light absorption patterns. Noninvasive brain […]

Because of silicon microelectronics (also known as chips or microchips), our smartphones and laptops are small but mighty. These tiny brains power almost all modern devices. However, this convenience comes with a price. Electronic devices will consume 25% of the world’s total energy by 2030. This is even though most of it is generated by burning carbon-rich […]

Fusion energy can provide safe, clean, and almost limitless power. Fusion reactions may occur for nuclei lighter than iron. However, they will not fuse unless exposed to extreme temperatures and pressures, such as those found in the interiors of stars. Scientists are looking for a fuel that is easy to produce, store and bring to fusion to create -burning […]

The ocean is one of the most unforgiving environments. Large swathes of the ocean remain unexplored due to its unpredictable weather patterns and limited communications. Wim van Rees is the ABS Career Development Professor at MIT. He says that “the ocean is a fascinating ecosystem with several current challenges like Microplastics and coral bleaching.” “At the same […]

The technology allows wireless communication, such as from your cell phone to a tower, which then channels it to the internet. 5G is a network service provided by telecommunications companies and is not the same as the 5GHz band on your Wi-Fi router. 5G has a magnitude (10x) greater bandwidth than 4G. The 5G network […]
