- How to help assembly-line robots shift gears and pick up almost anything
A University of Washington team created a new tool that can design a 3D-printable passive gripper and calculate the best path to pick up an object. The team tested this system on a suite of 22 objects -- including a 3D-printed bunny, a doorstop-shape…

Researchers have developed a new catalyst that improves the efficiency of converting butane, a component of natural gas, into butadiene -- a widely-used building block in synthetic rubber and a variety of plastics.
- 27 Jul 22, 6:13pm - - Breakthrough quantum algorithm
Physicists are claiming significant progress in using quantum computers to study and predict how the state of a large number of interacting quantum particles evolves over time. This was done by developing a quantum algorithm that they run on an IBM q…

- newNew analysis framework for developing stronger foundations during urban redevelopment
Urban redevelopment in densely populated areas often requires demolition and replacement of aging buildings. As buildings are replaced, existing foundation piles must be removed, leaving cylindrical voids that must be backfilled before the installati…
