Risk appetite of banks for small merchant renewable energy plants remains low

With more commercial banks pursuing bold sustainability targets in support of the Paris Agreement, there was an expectation that these plants would now find it easier to secure bank financing. However, a study published in the KeAi journal Global Transitions, suggests this is far from true.

7-step blueprint proposes new genetic and food security guidelines for aquaculture

Researchers from the Institute of Hydrobiology (IHB) at the Chinese Academy of Sciences, set out to reexamine fish biology and biotechnologies in the wake of these ongoing changes. Based on their findings, they have developed a new nine-step blueprint for improving the use of genetics and new breed creation in aquaculture species. In their paper, they also share their analysis of the potential of these new breeding strategies to improve the aquaculture seed industry and strengthen food security.

Researchers discover that the Omicron variant may have originated in mice

Findings suggest that researchers should focus on SARS-CoV-2 variants isolated from wild animals, especially rodents. If Omicron is determined to have been derived from mice, the implications of it circulating among non-human hosts will pose new challenges in the prevention and control of the epidemic

Women with older and overweight partners are at higher risk of embryo implantation failure

In a paper published in the KeAi journal Gynecology and Obstetrics Clinical Medicine, a group of researchers in China explored the effects of advanced paternal age (APA) and abnormal paternal weight (obesity) on in vitro fertilisation (IVF) treatment in nearly 800 couples who have experienced unexplained recurrent pregnancy loss (uRPL). Specifically, they considered the impact on embryo implantation, embryo quality and the health of the baby.

Researchers develop simple and scalable method of generating formate

Researchers used a one-step electrochemical anodic oxidation (AO) method to synthesise the nanoporous tin oxide using tin foil as the raw material. AO is a scalable, simple and efficient alternative for the preparation of nanoporous tin oxide, providing large specific surfaces, high porosity, and abundant grain boundaries. The researchers achieved a formate partial current density of 285 mA·cm-2 in a flow cell, with selectivity of 96.4%.

Why computational algorithms could transform COVID-19 diagnosis and care for low-income countries

In a study published in the KeAi journal Data Science and Management, a team of researchers from Africa and Canada tested the ability of seven computational algorithms to diagnose COVID-19 at an early stage, based on common symptoms. The researchers found that the algorithms Multilayer Perceptron, Fuzzy Cognitive Map and Deep Neural Network outperformed Logistic Regression, Naïve Bayes, Decision Tree and Support Vector Machine.
