“One of the most important scientific questions today is how many potential Earth-like Habitats (EHs) exist in the Galaxy, and how many of these planets could, in principle, support aerobic life?” according to an article in the peer-reviewed journal Astrobiology by Helmut Lammer and Manuel Scherf, from the Austrian Academy of Sciences, Space Research Institute. In two additional articles in Astrobiology, the authors, together with Laurenz Spross, from the University of Graz, derived a new formula that can be used to estimate the maximum occurrence rate of EHs in the Galaxy, and applied this formulation to the galactic disk by considering only requirements that are already scientifically quantifiable.

Suicide, a leading global health concern, ranks fourth among young people. Although many studies have reported temporal variations in suicide risk, most are limited to Western countries. Addressing this gap, researchers from Korea and Japan in collaboration with other countries conducted a multi-country multi-city study to investigate variations in suicide risk based on the day of the week and national holidays, revealing key insights that could help form effective and targeted suicide prevention action plans.

More children have overweight in regions with high rates of single parenthood, low education levels, low income and high child poverty. The pandemic may also have reinforced this trend. This is shown by a study conducted by researchers at Uppsala University and Region Sörmland in collaboration with Region Skåne.

- Professor Yong-Hoon Kim's team from the School of Electrical Engineering succeeded for the first time in accelerating quantum mechanical electronic structure calculations using a convolutional neural network (CNN) model

- Presenting an AI learning principle of quantum mechanical 3D chemical bonding information, the work is expected to accelerate the computer-assisted designing of next-generation materials and devices

Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a mathematical model that models how the evolutionary strategies of organisms are affected by the environment. They studied salmonid fishes which choose either to migrate to the sea then return to lay eggs or stay in the river depending on their individual features. Their model correctly predicts how the proportion choosing to migrate changes with environmental conditions, predicting how environmental change can trigger eco-evolutionary responses.
