- 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…

Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye... You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research. This highly innovative 'nano-robot' sho…

Researchers have developed a technique to control pH at the local level, creating a dense array of microsites where the amount of protons is 100 to 1000 times higher than the average in the rest of the solution.

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…

- new3D-printed interlocking electrodes demonstrate optimization potential for energy storage
Good electrochemical energy storage (EES) devices such as rechargeable batteries and supercapacitors can store a lot of energy and release it quickly, but these design goals are often at odds with each other. Using design optimization and 3D printing…

Building upon the chemistry that oysters use in miles-long reefs, scientists have found a way to create cement that is stronger and cures faster. Jonathan Wilker, a professor of chemistry in Purdue University's College of Science and an expert in adh…

Materials can store information about their past—like a crease in a piece of paper that has been unfolded is a "memory" of being folded—that can be retrieved or read out and used for various purposes. In everyday life, combination locks must reme…

In 1985, the Innovative Design Fund placed an ad in Scientific American offering up to $10,000 to support clever prototypes for clothing, home decor, and textiles. William Freeman Ph.D., then an electrical engineer at Polaroid and now an MIT professo…

At high speeds, even the smallest movement can have major consequences. When an aircraft tilts sharply during flight, the air around it does not flow smoothly. It twists into powerful, swirling currents that can destabilize the entire vehicle. These…
