Hybrid transistors set stage for integration of biology and microelectronics      (via sciencedaily.com)     Original source 

Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.

First experimental evidence of hopfions in crystals opens up new dimension for future technology      (via sciencedaily.com)     Original source 

Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. New findings open up new fields in experimental physics: identifying other crystals in which hopfions are stable, studying how hopfions interact with electric and spin currents, hopfion dynamics, and more.

Neanderthals were the world's first artists, research reveals      (via sciencedaily.com)     Original source 

Recent research has shown that engravings in a cave in La Roche-Cotard (France), which has been sealed for thousands of years, were actually made by Neanderthals. The findings reveal that the Neanderthals were the first humans with an appreciation of art.

NASA's Webb reveals new features in heart of Milky Way      (via sciencedaily.com)     Original source 

The latest image from NASA's James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way's central supermassive black hole, Sagittarius A*.

'Triple star' discovery could revolutionize understanding of stellar evolution      (via sciencedaily.com)     Original source 

A ground-breaking new discovery could transform the way astronomers understand some of the biggest and most common stars in the Universe.  Research by PhD student Jonathan Dodd and Professor René Oudmaijer, from the University's School of Physics and Astronomy, points to intriguing new evidence that massive Be stars -- until now mainly thought to exist in double stars -- could in fact be 'triples'.  The remarkable discovery could revolutionise our understanding of the objects -- a subset of B stars -- which are considered an important 'test bed' for developing theories on how stars evolve more generally.

Sophisticated swarming: Bacteria support each other across generations      (via sciencedaily.com)     Original source 

When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time.

Looking for 'LUCA' and the timing of cellular evolution      (via sciencedaily.com)     Original source 

LUCA, the 'last universal common ancestor' of all living organisms, lived 4.32 to at most 4.52 billion years ago. What LUCA looked like is unknown, but it must have been a cell with among others ribosomal proteins and an ATP synthase.

'Woman the hunter': Studies aim to correct history      (via sciencedaily.com)     Original source 

New research combined both physiological and archaeological evidence to argue that not only did prehistoric women engage in the practice of hunting, but their female anatomy and biology would have made them intrinsically better suited for it.

AI finds formula on how to predict monster waves      (via sciencedaily.com)     Original source 

Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs.

People watched other people shake boxes for science: Here's why      (via sciencedaily.com)     Original source 

When researchers asked hundreds of people to watch other people shake boxes, it took just seconds for almost all of them to figure out what the shaking was for. The deceptively simple work by perception researchers is the first to demonstrate that people can tell what others are trying to learn just by watching their actions. The study reveals a key yet neglected aspect of human cognition, and one with implications for artificial intelligence. 'Just by looking at how someone's body is moving, you can tell what they are trying to learn about their environment,' said author Chaz Firestone, an assistant professor of psychological and brain sciences who investigates how vision and thought interact. 'We do this all the time, but there has been very little research on it.'

'Teenage galaxies' are unusually hot, glowing with unexpected elements      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope, CECILIA Survey receives first data from galaxies forming two-to-three billion years after the Big Bang. By examining light from these 33 galaxies, researchers discovered their elemental composition and temperature. The ultra-deep spectrum revealed eight distinct elements: Hydrogen, helium, nitrogen, oxygen, silicon, sulfur, argon and nickel. The teenage galaxies also were extremely hot, reaching temperatures higher than 13,350 degrees Celsius.

AI system self-organizes to develop features of brains of complex organisms      (via sciencedaily.com)     Original source 

Scientists have shown that placing physical constraints on an artificially-intelligent system -- in much the same way that the human brain has to develop and operate within physical and biological constraints -- allows it to develop features of the brains of complex organisms in order to solve tasks.

Like the phoenix, Australia's giant birds of prey rise again from limestone caves      (via sciencedaily.com)     Original source 

Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again.    Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
