Older than the sun: Astronomers find new clues to the origin of interstellar comet 3I/ATLAS‎

Astronomers have used the European Southern Observatory's Very Large Telescope (ESO's VLT) to study the composition of 3I/ATLAS, the brightest interstellar object ever seen, in detail. By measuring specific chemical fingerprints—the first observations of this kind for a comet that formed outside the solar system—they found that 3I/ATLAS likely originated in the outskirts of an old star system.

Emotional ups and downs boost engagement but reduce sales in livestream influencer selling‎

Influencers who frequently switch between emotions during livestreams may attract more likes and comments, but they are likely to sell fewer products, according to new research from QUT. Published in the Journal of the Academy of Marketing Science, the research analyzed more than 12,900 product pitches and 80,600 minute-by-minute observations across 1,308 livestream selling sessions.

A new approach to measuring sheep liveweight‎

Sheep farmers could soon be able to estimate their flock's live weight and fleece weight in real time, without the need for labor-intensive handling. The new system, being developed by CSIRO, Australia's national science agency, will capture measurements in real time as animals move naturally through their environment. FlockMate is a two-year research project.

Bioinspired strategy creates complex 3D curved structures via programmed shrinkage‎

The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces with specific functional advantages, such as facilitating the drainage of water, increasing a structure's strength or aerodynamic efficiency, or supporting heavy loads.

Phylogenomics reveals angel insects' ancestry, resolving century‑old 'Zoraptera problem'‎

Zoraptera, also known as angel insects or ground lice, are tiny termite-like insects generally found underneath bark or in decaying wood. The Zoraptera group includes a few dozen known insect species that closely resemble each other.

Entrepreneurs more likely to be based in left wing areas‎

Research from the University of St. Andrews is challenging conventional assumptions about the relationship between politics and entrepreneurship. The study explored whether the political environment in which people live influences their likelihood of starting a business, and its findings reveal that areas with predominantly left-leaning political views have the highest rates of business creation, while areas with stronger right-wing political affiliations record the lowest.

Scholars examine how faculty define rigor in online college courses‎

A new article by scholars Jennifer L. James, Ph.D., Karen Myers, DNP, and Olivia Miller, M.A., in the Journal of Educators Online, titled "Studying Faculty Perceptions of Rigor in Online College Courses: Compromising or Accommodating?" examines how faculty perceive academic rigor when teaching, grading and managing online courses for nontraditional students.

Study reveals social enterprise well-being pressures‎

Social enterprises help communities thrive, but founder well-being is critical to sustaining their impact, UC research finds. Social enterprises create jobs, encourage ethical consumption, and address social and environmental challenges.

Did Israel's 'basket' initiative lower grocery bills?‎

Researchers from the Coller School of Management at Tel Aviv University examined the Ministry of Economy's flagship "Israel's Basket" initiative and found that although it substantially reduced the prices of the 100 products included in the program, these reductions were accompanied by price increases across many other product categories. According to the researchers, the overall impact on consumers' grocery bills may therefore have been considerably smaller than expected.

Researchers use AI to evaluate a systematic framework to describe molecular order in liquid water‎

Water is the most abundant liquid on Earth's surface, and it is highly anomalous compared with other liquids because it expands upon freezing. The anomalies in water have been linked to how its microscopic structure changes with temperature and pressure. However, there is no systematic scheme for characterizing these structural changes.
