The evolving periodicity of the brightness of certain types of stars can now be described mathematically.
An international study coordinated by researchers from IRD and CIRAD reveals the composition of the tropical forests of Central Africa and their vulnerability to the increased pressure from climate change and human activity expected in the coming decades. Thanks to an exceptional dataset - an inventory of over 6 million trees across five countries - the researchers have produced the first continuous maps of the floristic and functional composition of these forests, allowing them to identify the most vulnerable areas.
Ever wondered why your virtual home assistant doesn't understand your questions? Or why your navigation app took you on the side street instead of the highway? In a study published April 21st in the journal iScience, Italian researchers designed a robot that "thinks out loud" so that users can hear its thought process and better understand the robot's motivations and decisions.
A neural network that mimics the biology of the brain can be loaded onto a microchip for faster and more efficient artificial intelligence.
Underground pipelines that transport oil and gas are very important engineering communications worldwide. Some of these underground communications are built and operated in earthquake-prone areas. The research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect.
Optimizing network communication accelerates training in large-scale machine-learning models.
Muons, particles akin to electrons, have kepts physicists' heads spinning for more than a decade, because an experimental measurement of their magnetic properties disagrees with theory. Could this be caused by unknown particles or forces? A new theoretical calculation of this parameter, involving CNRS physicists and published in the journal Nature, has reduced the discrepancy with the experimental measurement. The debate nevertheless continues.
The U.S. and South Korea recorded their first official COVID-19 case on the same day, but there were notable differences in how each country addressed the world's most severe pandemic since 1918. A group of researchers recently conducted a study in which they applied data taken from South Korea's response to COVID-19 to develop a methodological framework for identifying pockets of COVID-19-vulnerable populations through the use of socioeconomic status and epidemiological determinants.
1. Fruit flies use antennae temperature differences of less than one degree to escape hot temperatures 2. Complex decision-making sheds light on ongoing challenges to developing self-driving vehicles 3. Principles learned from drosophila research could guide better, more efficient control systems for autonomous vehicles
A new study from the University of Central Florida suggests that masks and a good ventilation system are more important than social distancing for reducing the airborne spread of COVID-19 in classrooms. The research, published recently in the journal Physics of Fluids, comes at a critical time when schools and universities are considering returning to more in-person classes in the fall.
