Researchers at Oxford University’s Department of Materials, working in collaboration with colleagues from Exeter and Munster, have developed an on-chip optical processor capable of detecting similarities in datasets up to 1,000 times faster than conventional machine learning algorithms running on electronic processors.

The new research published in Optica took its inspiration from Nobel Prize laureate Ivan Pavlov’s discovery of classical conditioning. In his experiments, Pavlov found that by providing another stimulus during feeding, such as the sound of a bell or metronome, his dogs began to link the two experiences and would salivate at the sound alone...

Space study offers Clearest Understanding yet of the Lifecycle of Supermassive Black Holes

Black holes with varying light signatures but that were thought to be the same objects being viewed from different angles are actually in different stages of the life cycle, according to a study led by Dartmouth researchers.

The research on black holes known as “active galactic nuclei,” or AGNs, says that it definitively shows the need to revise the widely used “unified model of AGN” that characterizes supermassive black holes as all having the same properties.

The study, published in The Astrophysical Journal Supplement Series, provides answers to a nagging space mystery and should allow researchers to create more pre...

Researchers discover Gene that Promotes Muscle Strength during Exercise

Researchers have identified a gene that promotes muscle strength when switched on by physical activity, unlocking the potential for the development of therapeutic treatments to mimic some of the benefits of working out.

Published in Cell Metabolism, the University of Melbourne-led study showed how different types of exercise change the molecules in our muscles, resulting in the discovery of the new C18ORF25 gene that is activated with all types of exercise and responsible for promoting muscle strength. Animals without C18ORF25 have poor exercise performance and weaker muscles.

Project lead Dr Benjamin Parker said by activating the C18ORF25 gene, the research team could see muscles become much stronger, without them becoming necessarily bigger.

“Identifying this gene may impac...

Researchers develop Nanoporous Zinc Electrodes that make Primary Alkaline Zinc Batteries Rechargeable

A research team at The Hong Kong University of Science and Technology (HKUST) has developed a new electrode design that is set to enable the rechargeability of alkaline zinc batteries, one of the most common types of non-rechargeable batteries used in our daily lives, shedding light on a wider application of rechargeable batteries.

Batteries are ever important in the age of smart cities and global digitalization. Yet, a majority of batteries in the market are not rechargeable, or called primary batteries. They are disposed after a single use, an unsustainable practice that poses a serious threat to the environment.

Compared with other types of primary batteries, alkaline zinc batteries are cheap, safe, and energy-dense...
