Random robots are more reliable      (via sciencedaily.com)     Original source 

New algorithm encourages robots to move more randomly to collect more diverse data for learning. In tests, robots started with no knowledge and then learned and correctly performed tasks within a single attempt. New model could improve safety and practicality of self-driving cars, delivery drones and more.

This highly reflective black paint makes objects more visible to autonomous cars      (via sciencedaily.com)     Original source 

Driving at night might be a scary challenge for a new driver, but with hours of practice it soon becomes second nature. For self-driving cars, however, practice may not be enough because the lidar sensors that often act as these vehicles' 'eyes' have difficulty detecting dark-colored objects. New research describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer.

Feathers, cognition and global consumerism in colonial Amazonia      (via sciencedaily.com)     Original source 

Amazonia is the home of the largest variety of birds in the world. In such a unique environment, craft cultures have flourished by translating the beauty and creativity of environmental materials like feathers into stunning pieces of art. A new article examines artisanal featherwork within the context of early modern colonialism and globalization.

Marriage of synthetic biology and 3D printing produces programmable living materials      (via sciencedaily.com)     Original source 

Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid 'engineered living materials' are made by embedding cells in an inanimate matrix that's formed in a desired shape. Now, researchers have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.

The double-fanged adolescence of saber-toothed cats      (via sciencedaily.com)     Original source 

How did North America's saber-toothed cats hunt without breaking their unwieldy saber-like canines, which are vulnerable to sideways bending stresses? A paleontologist provides mechanical evidence that during adolescence, when young cats were learning to hunt, their baby teeth remained in place for up to 30 months to laterally buttress the emerging permanent sabers. By the time the baby teeth fell out, presumably the adult cat knew how to protect its sabers during attacks.
