Price noise proves the key to high performing ‘bets against beta’ investment strategies

Published 25 May, 2022

In a study published in the KeAi journal The Journal of Finance and Data Science, Thorsten Lehnert, a professor at the University of Luxembourg's finance department, shows that the strategies’ exposure to non-fundamental price pressure from trading activities of mutual funds explains their success. His analysis is based on more than 30 years of flow data from bond and equity mutual funds and focuses on the US stock market.

Researchers develop a membrane that stabilises lithium batteries

Published 23 May, 2022

Battery-powered electronic devices are now a necessity. However, these devices typically require charging at least once a day. Increasing the length of time between charges requires the development of batteries that can store more energy. While lithium metal electrodes promise to significantly improve energy density, their lack of stability means the batteries have a short service life and are associated with serious safety hazards. Researchers here demonstrate a new method to stabilise lithium electrodes.

Highway links benefit businesses – unless they are based outside cities

Published 19 May, 2022

A new study, published in the KeAi journal China Economic Quarterly International, has drawn on data related to China’s national trunk highway system (NTHS) to explore this issue. Researchers found that the construction of the five vertical and seven horizontal national trunk highways between 1998 and 2007, has not benefitted all regions along the NTHS, or the enterprises operating within them.

Researchers discover a gut microbiota that promotes fat development in lean pigs

Published 10 May, 2022

In a paper, published in the KeAi journal Animal Nutrition, he and his team explain how a comparison between the fat metabolic and gut microbial profiles of Shaziling pigs and the lean Yorkshire pig breed, led to them isolating a specific gut microbiota – Lactobacillus johnsonii – that can be used to increase the fat level and meat quality of lean pigs.

Scientists discover a new form of pesticide that neutralises pathogens attacking rice

Published 21 April, 2022

The major areas where rice are grown are blighted by pathogens - organisms that cause disease. To date, this problem has been treated with the use of chemical pesticides that typically target the plant-pathogenic fungi. But, with none of these treatments wholly effective, and many considered unfriendly to the environment. A group of researchers from China, Austria and Japan, outline a promising solution which uses a compound that has no harmful effects on the environment or humans consuming the rice.

New treatment removes radioactive barium from nuclear wastewater “rapidly and effectively”

Published 19 April, 2022

Scientists have focused on treating radioactive ions using an adsorption process, which causes the dangerous ions to stick to the adsorbent’s surface, which can then be safely scraped off. However, for this process to work safely and efficiently, achieving the right balance between adsorption capacity and adsorption speed is pivotal; something the various adsorbents that are currently used struggle to achieve. The authors of this paper have developed a new adsorbent that uses a sulfonic acid (–SO3H) group.

Yellow perch can expel microplastics from their bodies - but not without consequences

Published 11 April, 2022

A recent study explored how the consumption of feed contaminated with high-density polyethylene (HDPE) impacted yellow perch. The team found that while the fish can expel the microplastics from their guts, the effort results in reduced nutritional value of the fish, altered liver function and a change in the microbiota communities harboured in their guts.
