In a world first, La Trobe University researchers have discovered a virus that attacks a prominent disease-causing bacterium—a "ringleader" that recruits harmful bacteria to cause periodontitis, and potentially helps cancer grow and spread.
Quantum science has not only deepened human understanding of the structure of matter and its microscopic interactions, but also introduced a new paradigm of computing and information science—quantum computing and quantum simulation. Quantum informatics research has won the 2022 Nobel Prize in Physics.
The metal-carbon dioxide battery is a promising and environmentally friendly technology, but its energy efficiency is limited. Recently, a research team co-led by chemists from City University of Hong Kong (CityU) discovered an innovative way to overcome this problem by introducing an unconventional phase nanomaterial as a catalyst, boosting battery energy efficiency up to 83.8%. The study reveals a novel design of catalysts for the new generation of meta-gas batteries that can contribute to carbon neutral goals.
We have now discovered 30,039 near-Earth asteroids in the solar system—rocky bodies orbiting the sun on a path that brings them close to Earth's orbit. The majority of these were discovered in the last decade, showing how our ability to detect potentially risky asteroids is rapidly improving.
The ESA-led Solar Orbiter mission arrives at its next close approach to the sun on 12 October 2022 at 19:12 UTC (21:12 CEST). This sequence of images shows the progress of the ESA/NASA spacecraft as it heads inwards on its voyage of discovery. The sequence begins on 20 September and finishes on 10 October.
Researchers in Japan have identified different cockroach species based on egg casing impressions in Jomon-era pottery. Using the information, they found that the two main species in modern Japan had already been divided, east–west, at that time more than 5,000 years ago. Their work was published in the Journal of Archaeological Science: Reports on Aug. 30, 2022.
