A new way to 3D print complex structures recycles the material used for structural supports, significantly reducing the amount of waste generated.

Patients are being healed with a personalized treatment that repairs the patient’s specific genetic mutation. The treatment was created using a form of gene editing called base editing —a method created by UC San Diego’s Alexis Komor. Her latest research outlines the way certain DNA repair proteins can be manipulated to produce desired outcomes when using base editors.

A new NSF-funded study led by researchers from the U of A found that diatoms evolved slowly for the first 100 million years of their existence. Then, 170 million years ago, they reached an inflection point characterized by a burst of rapid speciation orders of magnitude faster than anything that had preceded it.

In a groundbreaking new study, a team led by scientists from the U.S. National Science Foundation (NSF) National Solar Observatory (NSO) has captured the sharpest-ever view of the Sun’s surface, revealing ultra-fine magnetic “stripes,” known as striations, just 20 kilometers wide—roughly the length of Manhattan. Using the NSF Daniel K. Inouye Solar Telescope, built and operated by the NSO, the team observed these bright and dark striations rippling across the walls of solar granules, caused by curtain-like magnetic fields that modify light much like fabric fluttering in the wind. The discovery uncovers a new layer of complexity in the Sun’s magnetic structure and demonstrates the Inouye Solar Telescope’s unmatched ability to resolve features previously thought beyond reach—offering new clues to how magnetism shapes solar phenomena.

Researchers have created dynamic structures that leap into the air on a predetermined schedule without intervention from computers or external stimuli. Precisely when these “metashells” jump, and how high they jump, is engineered into the physical structure of the materials.

Along with nutrients like nitrogen and phosphorus, iron is essential for the growth of microscopic phytoplankton in the ocean. However, a new study led by oceanographers at the University of Hawai‘i at Mānoa revealed that iron released from industrial processes, such as coal combustion and steel making, is altering the ecosystem in the North Pacific Transition Zone, a region just north of Hawai‘i that is important for fisheries in the Pacific.
