Nanorings: New building blocks for chemistry

Sandwich complexes were developed about 70 years ago and have a sandwich-like structure. Two flat aromatic organic rings (the “slices of bread”) are filled with a single, central metal atom in between. Like the slices of bread, both rings are arranged in parallel. Adding further layers of ‘bread’ and ‘filling’ produces triple or multiple sandwiches. “These compounds are among the most important complexes used in modern organometallic chemistry,” says Professor Peter ...

Sharing on Facebook reveals 2 very different news environments

COLUMBUS, Ohio – A first-of-its-kind study examined 2.2 million news stories shared on Facebook and found that publishers create two very different news environments.   These distinct ecosystems involve low-credibility publishers – those that publish what is sometimes referred to as fake news – versus high-credibility publishers.   Findings showed that while these two types of publishers often pushed out bursts of coverage at the same time – a common feature of news coverage – they were often about different topics, said Kelly Garrett, senior author of the study and professor of communication at The Ohio State University.   “These ...

Ear today, gone tomorrow? A new discovery in a cause of inner-ear bone loss

Osaka, Japan – Chronic inflammation of the middle ear can cause several problems and complications that can affect a person’s hearing and balance. One such problem is the formation of a cholesteatoma, which is an abnormal collection of cells in the ear that can cause bone erosion if left untreated. In turn, this can cause symptoms such as hearing loss, dizziness, facial paralysis, and even a brain infection. In a study published recently in Nature Communications, researchers from Osaka University have revealed the cause of cholesteatomas, which may help in developing new therapies for patients who are suffering ...

Robots cause company profits to fall – at least at first

Researchers have found that robots can have a ‘U-shaped’ effect on profits: causing profit margins to fall at first, before eventually rising again. The researchers, from the University of Cambridge, studied industry data from the UK and 24 other European countries between 1995 and 2017, and found that at low levels of adoption, robots have a negative effect on profit margins. But at higher levels of adoption, robots can help increase profits. According to the researchers, this U-shaped phenomenon is due to the relationship between reducing costs, developing new processes ...
