Robots Face the Future

Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.

Solar System Passed Through Dense Interstellar Clouds 2 Million Years Ago, Altering Earth's Climate

Two million years ago, Earth was undergoing multiple ice ages, possibly influenced by the solar system passing through a dense interstellar cloud. This cloud could have compressed the heliosphere, exposing Earth to cosmic rays and interstellar particles, which might have contributed to climatic changes. Astrophysicist Merav Opher's research suggests that the sun's location in the galaxy can significantly impact Earth's environment. Geological evidence supports this theory, showing increased radioactive isotopes from that period, hinting at the cosmic influence on Earth's climate history.
