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.

Researchers at the Georgia Institute of Technology have developed a new framework to evaluate how well AI chatbots can detect potential adverse drug reactions in chat conversations, and how closely their advice aligns with human experts. 

Researchers from the University of Rochester and University of California, Santa Barbara, engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the most delicate experiments in existence to observe and understand our universe.

Flooding in coastal communities is happening far more often than previously thought, according to a new study from North Carolina State University and the University of North Carolina at Chapel Hill. The study also found major flaws with the widely used approach of using marine water level data to capture instances of flooding.

Laboratory could improve crop resilience In a discovery three decades in the making, scientists at Rutgers and Brookhaven National Laboratory have acquired detailed knowledge about the internal structures and mode of regulation for a specialized protein and are proceeding to develop tools that can capitalize on its ability to help plants combat a wide range of diseases.

The work, which exploits a natural process where plant cells die on purpose to help the host plant stay healthy, is expected to have wide applications in the agricultural sector, offering new ways to protect major food crops from a variety of devastating diseases, the scientists said. The study was published in Nature Communications.

Seoul National University College of Engineering has announced that a joint research team led by Professor Hyobin Yoo from the Department of Materials Science and Engineering, in collaboration with Professor Young-Woo Son (Korea Institute for Advanced Study) and Professor Changwon Park (Ewha Womans University), has successfully developed a two-dimensional (2D) quantum material platform through the superposition of moiré lattices. The research was published online on May 14 in Nature, the most prestigious journal in science and technology, under the title “Unconventional domain tessellations in moiré-of-moiré lattices.” The study was supported by the National Research Foundation of Korea’s Young Researcher Program and SRC program, the POSCO Science Fellowship from the POSCO TJ Park Foundation, and the Korea Institute for Advanced Study. This study marks the first atomic-level identification of hierarchical structures and complex interlayer interactions resulting from the superposition of different moiré lattices in a trilayer graphene system. The work is expected to offer a promising new solid-state platform for the development of programmable quantum devices and next-generation electronic materials.
