Chemical engineers at the University of Pittsburgh Swanson School of Engineering have recreated collaboration and competition responses within a microchamber environment of microscopic particles, sheets, and catalysts, effectively mimicking responses of feeding, fighting, and fleeing.

As the world struggles to meet the increasing demand for energy, coupled with the rising levels of CO2 in the atmosphere from deforestation and the use of fossil fuels, photosynthesis in nature simply cannot keep up with the carbon cycle. But what if we could help the natural carbon cycle by learning from photosynthesis to generate our own sources of energy that didn't generate CO2?

Extreme ocean winds and wave heights are increasing around the globe, with the largest rise occurring in the Southern Ocean, University of Melbourne research shows.

A swarm of micro-robots, directed by magnets, can break apart and remove dental biofilm, or plaque, from a tooth. The innovation arose from a cross-disciplinary partnership among dentists, biologists, and engineers at the University of Pennsylvania.

A team of Japanese researchers has demonstrated preserving frozen animal cells without a cryoprotectant agent (CPA). To keep cells alive, all the conventional freezing methods needed to add a CPA, which can be potentially toxic and associated with cell damage. Their method only relies on ultrarapid cooling. A safe freezing without CPA would not only revolutionize how important research and medical material is stored, but greatly advance any and all research methods within those fields.

A team of scientists from NTU Singapore and NUHS has developed a self-inflating weight management capsule that could help battle obesity, and be an alternative to intragastric balloons. The prototype capsule contains a balloon that can be self-inflated with a handheld magnet once it is in the stomach, thus inducing a sense of fullness.
