Theoretical physicist Jonathan Heckman and Ph.D. student Rebecca Hicks at University of Pennsylvania put a spin on ideas related to testing string theory: Rather than looking to verify it, the team and their collaborators sought a novel way to falsify it with data from the Large Hadron Collider at CERN. “We're not rooting for string theory to fail,” Hicks says. “We're stress-testing it, applying more pressure to see if it holds up." “If string theory survives, fantastic," Heckman says. "If it snaps, we'll learn something profound about nature.”

The extent to which phase separation is involved in transcription has been contentious, with confounding arguments for the roles of small, soluble protein complexes and larger, phase-separated droplets. 

The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists at UC San Diego’s Scripps Institution of Oceanography.

The diver-operated microscope — called the Benthic Underwater Microscope imaging PAM, or BUMP — incorporates pulse amplitude modulated (PAM) light techniques to offer an unprecedented look at coral photosynthesis on micro-scales. Funded by the National Science Foundation, the new microscope will help scientists uncover precisely why corals bleach, and inform remediation efforts. While the bleaching process is known, it’s not fully understood, and it hasn’t been possible to study in depth in the field — until now.

 A team of researchers from the University of Notre Dame, Harvard Medical School/Massachusetts General Hospital, and Boston University has developed a technique for measuring a brain tumor’s mechanical force and a new model to estimate how much brain tissue a patient has lost. 

With a new mapping tool, Princeton engineers have revealed how a factory inside cells builds ribosomes, the machinery responsible for protein synthesis. The system opens the door to treatments and medicines.

University of Washington researchers developed the game AI Puzzlers to show kids an area where AI systems still typically and blatantly fail: solving certain reasoning puzzles. In the game, users get a chance to solve puzzles by completing patterns of colored blocks. They can then ask various AI chatbots to solve and have the systems explain their solutions — which they nearly always fail to do accurately.

Cognitive neuroscientists at Brown University investigated one of humanity’s favorite pastimes and discovered how people can spread gossip without the subject of that gossip finding out — at least not right away. In a study supported by a federal grant from the National Science Foundation, the researchers found that gossiping relies on a person’s ability to perform complex computational processes each time they decide to spread information, and that most people do this instinctively.
