A team of scientists have successfully demonstrated the world’s first cosmic-ray GPS to detect movement underground and in volcanoes which can potentially aid in future search-and-rescue missions.

Cosmic rays are high-energy particles originating from outer space, including sources such as the sun, distant galaxies, supernovae, and other celestial bodies. Although we can’t see or feel cosmic rays directly, they constantly bombard the Earth from outer space.

In fact, these particles are so abundant that scientists estimate one cosmic ray hits one square centimeter of the Earth’s surface every minute! Scientists study cosmic rays to learn about the universe and how particles interact at high energies.

Current artificial intelligence systems like ChatGPT do not have human-level intelligence and are not even as smart as a dog, Meta’s AI chief Yann LeCunn said. LeCun talked about the limitations of generative AI, such as ChatGPT, and said they are not very intelligent because they are solely trained on language.

Meta’s LeCun said that, in the future, there will be machines that are more intelligent than humans, which should not be seen as a threat.

Current artificial intelligence systems like ChatGPT do not have human-level intelligence and are barely smarter than a dog, Meta’s AI chief said, as the debate over the dangers of the fast-growing technology rages on.

Hurling spear-thrower projectiles at archery targets revealed that these loops may have been finger grips.

When prodded with a tiny glass rod, leaves released waves of calcium signals to cells that quickly diminish after the touch.

Denmark was in full chaotic collapse in the early 19th century. Why was its art so beautifully serene?

Scientists have taken a journey back in time to unlock the mysteries of Earth’s early history, using tiny mineral crystals called zircons to study plate tectonics billions of years ago. The research sheds light on the conditions that existed in early Earth, revealing a complex interplay between Earth’s crust, core, and the emergence of life.

Plate tectonics allows heat from Earth’s interior to escape to the surface, forming continents and other geological features necessary for life to emerge. Accordingly, “there has been the assumption that plate tectonics is necessary for life,” says John Tarduno, who teaches in the Department of Earth and Environmental Sciences at the University of Rochester. But new research casts doubt on that assumption.

Tarduno, the William R. Kenan, Jr. Professor of Geophysics, is lead author of a paper published in Nature examining plate tectonics from a time 3.9 billion years ago, when scientists believe the first traces of life appeared on Earth.

The technology can help cut through buzzwordy “solutions” and serve as a shortcut for jumpstarting creativity.

Buying art in cryptocurrency has seen record-breaking prices followed by a crash in recent years, but there are ways to remove the volatility to benefit both artists and buyers.
