Oldest known fossilized skin is 21 million years older than previous examples      (via sciencedaily.com)     Original source 

Researchers have identified a 3D fragment of fossilized skin that is at least 21 million years than previously described skin fossils. The skin, which belonged to an early species of Paleozoic reptile, has a pebbled surface and most closely resembles crocodile skin. It's the oldest example of preserved epidermis, the outermost layer of skin in terrestrial reptiles, birds, and mammals, which was an important evolutionary adaptation in the transition to life on land.

Largest diversity study of 'magic mushrooms' investigates the evolution of psychoactive psilocybin production      (via sciencedaily.com)     Original source 

The genomic analysis of 52 Psilocybe specimens includes 39 species that have never been sequenced. Psilocybe arose much earlier than previously thought -- about 65 million years ago -- and the authors found that psilocybin was first synthesized in mushrooms in the genus Psilocybe. Their analysis revealed two distinct gene orders within the gene cluster that produces psilocybin. The two gene patterns correspond to an ancient split in the genus, suggesting two independent acquisitions of psilocybin in its evolutionary history. The study is the first to reveal such a strong evolutionary pattern within the gene sequences underpinning the psychoactive proteins synthesis.

Towards more accurate 3D object detection for robots and self-driving cars      (via sciencedaily.com)     Original source 

Robots and autonomous vehicles can use 3D point clouds from LiDAR sensors and camera images to perform 3D object detection. However, current techniques that combine both types of data struggle to accurately detect small objects. Now, researchers have developed DPPFA Net, an innovative network that overcomes challenges related to occlusion and noise introduced by adverse weather. Their findings will pave the way for more perceptive and capable autonomous systems.

A groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease and climate change. The study challenges the long-standing belief about the unpredictability of evolution, and has found that the evolutionary trajectory of a genome may be influenced by its evolutionary history, rather than determined by numerous factors and historical accidents.
