Credit: NASA, Jim Watson / Getty ImagesAn asteroid notoriously erased the dinosaurs about 66 million years ago. Could one more one do the very same to us? That question has led NASA researchers and designers to create the DART program, whose duty was to redirect the motion of an asteroid. The mission was a...
The Arecibo Observatory’s 305-metre-wide telescope dish partially collapsed in late 2020, after some supporting cables had snapped. Credit: Ricardo Arduengo/AFP via GettyAfter one world-famous radio telescope at Arecibo Observatory in Puerto Rico collapsed 2 years back, many scientists hoped that the United States National Science Foundation (NSF), which runs the facility, would eventually build...
The system worked 3 times better than today's state-of-the-art passive cooling system.As the world's climate continues to warm up, the world demand for air conditioning is currently skyrocketing. In 2019, the requirement for cooling drew in 8.5% of the globe's total electricity consumption, equating to some one billion tons of carbon dioxide emissions.As more...

It is only under the microscope that the similarity of its namesake becomes apparent: the plump, round physique and the short legs are reminiscent of those of a bear.

A few weeks back, while reading the news about SIGGRAPH, I saw NVIDIA teasing the launch of the Omniverse connector for Unity. Also, as a Unity creator, I found it intriguing. I asked for the chance to have more info about it, and I had the pleasure of having a talk with Dane Johnston,...

Recently, we ran a piece including the views of well-known science writer John Horgan who talked about a bizarre element of quantum physics confirmed by recent experiments-- that it appears as if there´s no knowledge apart from observers' minds.Theoretical physicist Sabine Hossenfelder is decidedly not happy with that approach:" Physicists have revealed that objective...
