The universe hums with gravitational waves. Here’s why scientists are so excited about the discovery

The very fabric of the universe rings with gravitational waves from its earliest epoch, and researchers have finally “heard” this cosmic symphony. On Thursday, June 28, the North American Nanohertz Gravitational-Wave Observatory (NANOGrav) announced the detection of low-frequency gravitational waves, a historic achievement that represents a 15-year search. However, this is not the first time … Read more

This AI tool explains how AI "sees" images and why it can mistake an astronaut for a shovel

https://openaccess.thecvf.com/content/CVPR2023/papers/Fel_CRAFT_Concept_Recursive_Activation_FacTorization_for_Explainability_CVPR_2023_paper.pdf It is widely acknowledged that artificial intelligence (AI) has made significant strides in recent years, resulting in significant breakthroughs and breakthroughs. However, it is not true that AI can achieve equally impressive results in all tasks. For example, while AI can outperform humans in certain visual tasks, such as face recognition, it can also … Read more

Research reveals how genetics interact with social forces and the environment

Research reveals how genetics interact with social forces and the environment

Humans are a diverse species. Every person on Earth has enough DNA to reach Pluto three times. Studying how all this genetic material works, and in particular how genes influence human behavior, is a very complex endeavor, aided by the introduction of large genetic data banks and powerful data science analytical tools to analyze this … Read more

We've Pumped So Much Groundwater We've Caused a Pole Shift - Digital Journal

Many Americans rely on groundwater sources for their drinking water. Credit _ Environmental Protection Agency, State Dpmain Sea level rise due to groundwater withdrawal has caused the Earth’s pole of rotation to drift by nearly a meter over two decades. By pumping water out of the ground and moving it elsewhere, humans have moved so … Read more

The research deepens our understanding of how humans affect climate change

The research deepens our understanding of how humans affect climate change

This was done by isolating and quantifying the effects of the two forces using coupled climate model simulations. The researchers found that aerosol-driven changes in ocean circulation and the associated interbasin heat transport capabilities are more effective at altering the distribution of ocean heat than those caused by globally increasing GHGs. “A better understanding of … Read more

NASA enlists four volunteers on a one-year mission in a simulated Martian habitat

the universe today

On June 25, 2023, a crew of four volunteers entered a simulated Martian habitat, from which they would not emerge for more than a year. Their mission: to learn more about the logistics – and human psychology – of living on another planet for long periods of time without ever leaving the place. The mission, … Read more

How did dinosaurs get so big? Scientists now have an answer

SAO PAULO, Brazil — How did dinosaurs turn from small creatures into colossal giants? Researchers at the State University of Campinas (UNICAMP) in São Paulo state, Brazil, believe they finally have an answer. In a new study, they explain that the air sac formed the ancient dinosaur Macrocollum itaquii is the key to understanding the … Read more
