New interpretation of runic inscription reveals pricing in Viking age      (via sciencedaily.com)     Original source 

A new interpretation of the runic inscription on the Forsa Ring (Forsaringen in Swedish), provides fresh insights into the Viking Age monetary system and represents the oldest documented value record in Scandinavia. The inscription describes how the Vikings handled fines in a flexible and practical manner.

Rewriting the evolutionary history of critical components of the nervous system      (via sciencedaily.com)     Original source 

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.

Engineers make tunable, shape-changing metamaterial inspired by vintage toys      (via sciencedaily.com)     Original source 

Common push puppet toys in the shapes of animals and popular figures can move or collapse with the push of a button at the bottom of the toys' base. Now, a team of engineers has created a new class of tunable dynamic material that mimics the inner workings of push puppets, with applications for soft robotics, reconfigurable architectures and space engineering.

AI poses no existential threat to humanity, new study finds      (via sciencedaily.com)     Original source 

Large Language Models (LLMs) are entirely controllable through human prompts and lack 'emergent abilities'; that is, the means to form their own insights or conclusions. Increasing model size does not lead LLMs to gain emergent reasoning abilities, meaning they will not develop hazardous abilities and therefore do not pose an existential threat. A new study sheds light on the (until now unexplained) capabilities and shortcomings of LLMs, including the need for carefully engineered prompts to exhibit good performance.

Scientists find oceans of water on Mars: It's just too deep to tap      (via sciencedaily.com)     Original source 

Quakes and meteor impacts on Mars generate seismic waves that can help map the interior. A new study analyzed seismic waves detected by the Insight lander and concludes that 11-20 kilometers beneath the surface, a zone of pores and fractures is filled with liquid water -- more than was thought to fill Mars' surface oceans before they disappeared 3 billion years ago. Though too deep to drill, the reservoir is a possible refuge for life.

New technology uses light to engrave erasable 3D images      (via sciencedaily.com)     Original source 

Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.

Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity      (via sciencedaily.com)     Original source 

A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.

3D-printed blood vessels bring artificial organs closer to reality      (via sciencedaily.com)     Original source 

Lab-grown organs are a long-time 'holy grail' of organ engineering that has yet to be achieved, but new research has brought that goal a big step closer to reality using a new 3D-printing method called co-SWIFT. co-SWIFT prints branching networks of double-layered vessels that are infused with smooth muscle cells and endothelial cells into living human cardiac tissue, and can even replicate patient-specific vascular structures,indicating that it could one day be used for personalized medicine.

Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.
