The doughnut-shaped rings surrounding many supermassive black holes tell researchers how fast extraterrestrial objects are feeding and could change how black holes are viewed from Earth. Credits: ESA/NASA, AVO project and Paolo Padovani The researchers used X-ray telescopes and new data analysis techniques to describe extraterrestrial objects. Black holes with different light signatures that were once thought to be the same object viewed from different angles are actually in different stages of their life cycle, according to a study led by Dartmouth scientists. New research on black holes known as “active galactic nuclei,” or AGNs, says that it definitively demonstrates the need to revise the widely used “AGN unified model” that characterizes supermassive black holes because they all share the same properties. This study provides an answer to a troubling space mystery and should allow researchers to create more precise models of the evolution of the universe and...

Due to the extensive use of nanoparticles, toxicologists and scientists alike are interested in better understanding their safety profile. The toxic effects of nanoparticles on macrophages, for example, require further research, as these immune cells often first encounter nanoparticles after they enter the body. Recently Life Science In the study, researchers discussed the molecular changes, as well as the underlying mechanisms, that appear in macrophages after their interaction with nanoparticles. Study: An in vitro review of nanoparticles attacking macrophages: Cell interactions and death. Image Credit: Kateryna Kon / Shutterstock.com Background Nanoparticles can be engineered or natural particles that are smaller than 100 nanometers (nm) in at least one dimension. Over the past few decades, nanotechnology has developed rapidly, which has subsequently increased the demand for nanoparticles such as titanium dioxide, zinc oxide (ZnO), graphene, and smaller quantum dots. These n...

The coronavirus disease 2019 (COVID-19), caused by infection with acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused more than 6.4 million deaths to date. new Cannabis and Cannabinoid Research a journal study discusses the usefulness of cannabidiol (CBD) in treating the inflammatory symptoms of COVID-19. This treatment approach can help contain or reduce the progression of COVID-19, thereby potentially lowering its severity and mortality. Study: Cannabidiol As a Treatment for COVID-19 Symptoms? Critical Review . Image Credit: r.classen / Shutterstock.com introduction COVID-19 is associated with a wide spectrum of presentations from mild to life-threatening illness. The hyper-inflammatory reaction to SARS-CoV-2 is thought to be responsible for the severe symptoms involving multiple organ systems. Various drugs have been evaluated for their ability to reduce the severity of COVID-19. These include dexamethasone, a potent corticosteroid with anti-inflammatory and immun...

Paul Haskell-Dowland has been in the cybersecurity research and education domain for two decades — and it’s his mission to teach us all how to stay safe online. This is important work for the Edith Cowan University Professor of Cybersecurity Practice. The cost of cybercrime in Australia is very high, although the figures are likely to be even greater than the reported data suggest. Cybercriminals operate in a highly sophisticated environment. ( Provided: Paul Haskell-Dowland ) “Estimated [a couple of years ago] that the global cost of cybercrime … will reach the $1 trillion mark, and I believe it has passed that,” he said. “It’s very difficult to get an accurate indication of these numbers, because so much cybercrime goes unreported.” Professor Haskell-Dowland, who is also Associate Dean for Computing and Security, said for many people their only insight into the world of cybercrime is what is portrayed in the media in films like Hacker, and ev...

While the economy of electric buses may make them an increasingly attractive public transportation option, 4th grader Annabelle Nicolson has different reasons to love her new electric ride to school. Key points: Hillcrest Christian College begins trial of the first school-run electric bus on the Gold Coast Transport research shows car dependence increases congestion around schools A Griffith researcher predicts absorption in the use of electric vehicles in public transport as costs fall “If the gas is released from the bus into the air, then we, plants and animals can get sick,” he said. Annabelle will be one of the first students at Hillcrest Christian College to board her new electric bus as part of an upcoming trial. The trial is the only one of its kind on the Gold Coast, with the school hoping to transition its fleet over five years. But according to the Griffith University Transportation Research Group, as fuel prices rise and maintenance costs fall, more schools will ...

Some systems link lenders to borrowers, and depending on how much demand is on both sides, calculate the ‘interest rate’ for the investor tipping the money. These are called “automated lending protocols,” and the biggest ones were Aave, Maker and Compound, which fell 65 percent, 59 percent, and 72 percent, respectively. DeFi also offers “automated market makers” or decentralized exchanges, which automatically connect buyers and sellers and also provide liquidity to the market. The biggest ones are Uniswap, Curve and PancakeSwap which are down 60 percent, 78 percent and 67 percent respectively since January 1. Australia’s DeFi projects include Synthetix, which is down 38 percent, Maple Finance, which is down 14 percent. . While token prices are the most obvious way to track the performance of a DeFi project, the results show how much demand there is for the system. For example, if many people want to lend their money, the yield is high. When people don...
