Making scents of cannabis: How cannabis cultivar and preparation methods influence aroma‎

Ongoing research reveals how the aroma of cannabis is influenced not only by the chosen cultivar, but also by different drying and storage methods. Through a combination of high-resolution chromatography and human-perception aroma assessments, this project provides detailed insights into the impact of preparation and transportation on cannabis chemistry and how humans perceive and interpret its aromas.

New biobased polymers exhibit excellent tensile properties beyond polyolefins‎

The research group of Professor Kotohiro Nomura, Tokyo Metropolitan University, in cooperation with the research groups of Senior Researcher Hiroshi Hirano and Director Seiji Higashi of the Osaka Research Institute of Industrial Science and Technology, and Associate Professor Hiroki Takeshita of The University of Shiga Prefecture, has developed biobased poly(ester amide)s from inedible biorenewables that can be easily chemically recycled and exhibit better mechanical (tensile) properties in film than commodity plastics.

Newly discovered mineral named for researcher Tyler Spano‎

Tyler Spano's impact on the field of mineralogy is anything but small. So when a newly discovered mineral, modest in size but significant in meaning, was named spanoite in her honor, it became a fitting tribute to her contributions to the field.

Q&A: Harnessing climate investments to serve development goals‎

Climate pledges are designed to help countries reduce emissions and adapt to a changing climate, but the current iterations of these pledges place additional stresses on vulnerable nations, an international team of researchers co-led by University of Michigan Engineering and KTH Royal Institute of Technology in Sweden has shown.

How an interstellar comet sheds light on universe's 'cosmic noon'‎

Last year, an interstellar traveler entered our solar system. Some speculated that it was an alien spacecraft, but it turned out to be a comet, 3I/Atlas, and it provoked interest from astronomers and astrophysicists eager for insights into galaxies far, far away. Detailed observations from the National Aeronautics and Space Administration (NASA) shot down the alien spacecraft idea, but recent NASA analysis holds clues about the comet's ancient and, literally, alien origins.

Efficient method for preparing pseudopregnant mice promotes laboratory animal welfare‎

In biomedical research using mouse models, preparing pseudopregnant recipient females is a standard step in embryo transfer protocols. Conventionally, this process requires technicians to select female mice showing clear signs of estrus. Because only a limited percentage of mice naturally enter this stage daily, facilities often maintain a relatively large stock of female mice. Furthermore, group housing can induce the "Lee-Boot effect," a biological phenomenon in which caged females suppress one another's estrous cycles, decreasing selection efficiency and requiring careful management to ensure animal well-being.

What everyone gets wrong about the modern job search—and what actually works‎

Job searching has never been more accessible—or more confusing. Platforms like LinkedIn, Indeed and employer career pages let candidates submit applications with just a few clicks. What happens after they click "submit," however, has become fertile ground for misinformation.

AI system translates protein sequences into text, helping reveal functions of unknown proteins‎

In a paper published in Proceedings of the National Academy of Sciences, researchers from Technion and Tel Aviv University present BetaDescribe, an AI system that translates protein sequences into natural-language descriptions, opening a new path toward understanding protein functions and accelerating drug development and material design.

Newly identified marine bacterial enzyme opens new route to building bioactive compound libraries‎

Many important medicines and agricultural compounds have origins in natural products made by microorganisms. One such compound is prodigiosin, a vivid red pigment produced by certain bacteria. Beyond its color, prodigiosin and related compounds known as prodiginines have attracted scientific interest because they have shown antibacterial, anticancer, immunosuppressive, antifungal and plant-protection activities.
