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.

Artificial Intelligence is breaking new barriers by the day. Hundreds of worshippers at St. Paul’s Church in Fürth, Bavaria, Germany recently attended a service, entirely conducted by AI with the sermon being presented by the AI chatbot ChatGPT.
An hour before the service even began, people formed a long queue outside the 19th-century, neo-Gothic building to witness what the AI could deliver.
The chatbot’s sermon majorly focused on themes surrounding leaving one’s past behind, living in the present, not being afraid of death and maintaining faith in Jesus Christ. Notably, four different AI avatars took turns to impart the sermons and lead the service.
An international team of researchers from the University of Turku, Finland, and the INRAE of Nouzilly, France, explored the ability of sledging reindeer to follow directional indications from humans. Their results highlight that reindeer, which are well habituated to humans, can make use of gestural cues very well with minimal training.
Working animals, such as equines, shepherd dogs, and logging elephants, spend a significant amount of time interacting closely with humans to fulfill specific tasks. Effective communication plays a crucial role in their working relationship. Animals’ understanding of human cues, particularly manual pointing gestures, is an important aspect of this communication.
The use of pointing gestures to communicate with others and to show them where to look or to go is very natural for humans. For other animals that do not use this way of communication, the gesture may not always be easy to understand. For this reason, the pointing gesture is often used in experiments to see if animals can understand cues that are specific to humans.
Japanese company PowerX has unveiled the detailed design of the first-ever “Battery Tanker” at the Bariship International Maritime Exhibition held in Imabari City, Ehime Prefecture, Japan.
For over a century, oil tankers have been a familiar sight on international shipping routes, delivering vital energy sources to power our civilisation. But as the world shifts away from fossil fuels, they could soon be joined by new and futuristic-looking vessels bringing cleaner forms of energy.
