Hydrogels can play Pong by 'remembering' previous patterns of electrical simulation      (via sciencedaily.com)     Original source 

Non-living hydrogels can play the video game Pong and improve their gameplay with more experience, researchers report. The researchers hooked hydrogels up to a virtual game environment and then applied a feedback loop between the hydrogel's paddle -- encoded by the distribution of charged particles within the hydrogel -- and the ball's position -- encoded by electrical stimulation. With practice, the hydrogel's accuracy improved by up to 10%, resulting in longer rallies. The researchers say that this demonstrates the ability of non-living materials to use 'memory' to update their understanding of the environment, though more research is needed before it could be said that hydrogels can 'learn.'

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.

Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis      (via sciencedaily.com)     Original source 

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.

Half a billion-year-old spiny slug reveals the origins of mollusks      (via sciencedaily.com)     Original source 

Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
