Fidget poppers are an example of “bistability,” as the popped circles rest in one of two stable states. Purdue University researchers have taken this idea to its extreme, building robots that can be preprogrammed and controlled using just the physical properties of these fidget poppers.

A new molecular switch, created through protein design, may be a potential way to control when drugs are active or inactive in the body. Researchers hope this approach is a starting point for further developments to reduce side effects from cancer drugs or antibody therapies. This type of designed molecular switch has already been shown to increase the speed of a COVID test. The scientists have also created a switchable version of interleukin-2 in a effort to manage the side effects of this potentially powerful cancer drug. 

MIT researchers identified mucins that defend against Salmonella and other bacteria that cause diarrhea. They now hope to create synthetic mucins that could help prevent or treat Salmonella and other foodborne infections.

CUNY Graduate Center Professor Leora Yetnikoff receives $1 million from the National Science Foundation to explore the links between social isolation, dopamine, and behavior.

Iowa State engineers are joining researchers from across the country to develop new tools to simulate electrochemical processes critical to energy, health care and manufacturing. The U.S. National Science Foundation is supporting the project.

Caltech physicists have created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in a grid by lasers. Previous arrays of this kind contained only hundreds of qubits.   

Rice researchers used a focused electron beam to pattern device functions with submicron precision directly into an ultrathin crystal.
