| Embryonic development in a petri dish Posted: 10 Dec 2020 11:58 AM PST By growing mouse stem cells in a special gel, a research team succeeded to grow structures similar to parts of an embryo. The trunk-like structures develop the precursors for neural, bone, cartilage and muscle tissues from cellular clumps within five days. This could allow the investigation of the effects of pharmacological agents more effectively in the future -- and on a scale that would not be possible in living organisms. |
| 'Electronic amoeba' finds approximate solution to traveling salesman problem in linear time Posted: 10 Dec 2020 08:20 AM PST Researchers have, inspired by the efficient foraging behavior of a single-celled amoeba, developed an analog computer for finding a reliable and swift solution to the traveling salesman problem -- a representative combinatorial optimization problem. |
| Getting the right grip: Designing soft and sensitive robotic fingers Posted: 10 Dec 2020 08:20 AM PST To develop a more human-like robotic gripper, it is necessary to provide sensing capabilities to the fingers. However, conventional sensors compromise the mechanical properties of soft robots. Now, scientists have designed a 3D printable soft robotic finger containing a built-in sensor with adjustable stiffness. Their work represents a big step toward safer and more dexterous robotic handling, which will extend the applications of robots to fields such as health and elderly care. |
| New 'sea dragon' discovered off UK coastline Posted: 09 Dec 2020 11:03 AM PST An amateur fossil hunter has unearthed a new type of prehistoric 'sea dragon' on the beach of the UK's Dorset coast. |
| Charles Darwin was right about why insects are losing the ability to fly Posted: 09 Dec 2020 06:42 AM PST Most insects can fly. Yet scores of species have lost that extraordinary ability, particularly on islands. |
