Generative AI tools like ChatGPT present extraordinary potential in promoting better language learning and teaching practice, such as timely feedback, ease of use, personalized support, simulations of the learning environment, and individualized recommendations on learning materials. However, a team of researchers in Hong Kong and Macao found that 45.9% of ChatGPT-generated feedback was rejected by second-language students, higher rejection rates for content-focused feedback (58.7%) than form-focused (41.3%).

Johannes Gutenberg University Mainz (JGU) honors materials scientist Professor Anna Balazs from the University of Pittsburgh, USA, with the 2025 Gutenberg Research Award. This award is JGU's most eminent research prize, endowed with EUR 10,000 and conferred annually by the Gutenberg Research College, the central institution designed to promote top-level research at Mainz University.

Scientists from UC San Diego have uncovered a key finding to one of water's unique properties: at high pressure and low temperature, liquid water separates into two distinct liquid phases — one high-density and one low-density.

Shimadzu Corporation, a global leader in the precision instrumentation industry, and Diagnostics Development Hub (DxD Hub), a national platform hosted by Singapore’s Agency for Science, Technology and Research (A*STAR), are pleased to announce a strategic collaboration to establish the Shimadzu – DxD Hub Diagnomics Centre (SDDC) at Biopolis, Singapore. Officially launched today, the SDDC will drive innovation and accelerate the development of diagnostic products by integrating Shimadzu’s technological expertise with DxD Hub’s productisation platforms.

The Biodiversity Data Journal (BDJ) portal is now available on the Biodiversity Information Facility (GBIF) platform, offering open access to data about all types of life on Earth. The BDJ portal provides access to nearly 300,000 biodiversity records from around the world, along with more than 800 datasets and over 1,000 citations. Users can search for data by taxonomy, location, IUCN Red List category, and other criteria. The portal also provides statistics and clustering features to help users explore the data more efficiently.

Ventilation is an important process within the global ocean, where waters sink to deeper layers, are transported by deep currents, and eventually upwelled back to the surface. This process affects the distribution of oxygen and carbon in the global ocean by transporting these elements from the surface to deeper regions of the ocean. Scientists are still trying to understand the exact dynamics and circulation pathways that determine how dense, cold water from deep in the Gulf of Mexico gets circulated within the Gulf. Current theories suggest that deep water is transformed into intermediate water through small scale mixing which drives upwelling before flowing out of the Gulf through the Yucatán Channel.

Semantic communication, an emerging technology, has garnered considerable attention for its potential to enhance transmission efficiency. This approach emphasizes the precise transmission of semantic information rather than individual symbols or bits, facilitating purposeful information exchange for efficient transmission. Researchers have proposed a novel semantic communication transmission system using multimode fiber, achieving high spectral efficiency and demonstrating its effectiveness in sentiment analysis applications.
