Scientists Rethink Evolution of Insects After Discovery of 500 Mn Years Old Fossils

A new study of a fossil cache sheds fresh light on the evolutionary history of insects and spiders, notably the brain, eyesight, and head shape. The fossils comprised well-preserved remnants of the brains and neurological systems of Stanleycaris, a three-eyed predator. Despite the predator being over half a billion years old, the neural structures have …

DeepMind AI reacts to impossible situations much like a baby • The Register

DeepMind has looked to developmental psychology to help AI gain a basic understanding of the physical world. Real-world physics are difficult for AIs to grasp when asked to start from scratch with only training data to guide them. But researchers have babies as young as five months are surprised if they are shown a physically …

2 Edmonton scientists excited to use James Webb telescope for their research

As more images from the James Webb Space Telescope are expected to come out Tuesday, two Albertan astrophysicists are full of anticipation. Canada is guaranteed five per cent of the telescope’s working time, and two scientists from the University of Alberta are ready to use some of it for their research. The work on the …

Greg Robinson Fixed NASA’s James Webb Space Telescope, Reluctantly

In 2018, the James Webb Space Telescope, the beleaguered project to build an instrument that could gaze back to the earliest stars in the universe, appeared to be going off the rails. Again. The pieces of the telescope and its instruments were complete, but they needed to be assembled and tested. The launch date was …

Designing surfaces that make water boil more efficiently

The key to the new surface treatment is to add textures at several different size scales. Electron microscope images show millimeter-scale pillars and teeth(first two images), whose surfaces are covered with tiny nanometer-scale ridges (bottom two images) to improve the efficiency of the boiling reaction.

NASA has turned ocean data into music – The Vinyl Factory

Published on July 12, 2022 Category News No seashell required. A NASA scientist and his programmer brother have made an online program that turns ocean data into sound. The pair have worked on the project for the past 18 months, hoping to use it to encourage people to “appreciate the connectivity of our Earth’s ocean.” …

The best offense is a great defense for some carnivorous plants

Credit: Pixabay/CC0 Public Domain Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Now, Salk scientists, along with collaborators from Washington University in St. Louis, have investigated the molecular basis of plant carnivory and found evidence that …
