🔬 Nanofluid tapes boost heat transfer performance

Researchers studied the thermo-hydraulic performance of twisted-tape inserts with MWCNT–Fe3O4 hybrid nanofluids. This study was conducted using plain tube and twisted-tape geometries across various flow velocities and inlet temperatures. The TT-90° configuration showed the best performance, yielding a 39.8% net improvement at Re = 5000. The hybrid nanofluid helped heat transfer but also added hydraulic resistance compared to distilled water. Overall, combining nanofluid and high-angle tapes gives superior thermo-hydraulic results, especially at lower flow rates.

🔬 Waste rock mix gets a glow-up with phosphogypsum

Researchers studied the mechanical behavior of backfill made from waste rock and phosphogypsum. The study was conducted by multiple authors at Wuhan University of Technology and other institutes. Slurry mixtures showed favorable transport at 78% mass concentration, as per tests on September 1, 2026. Phosphogypsum addition improved workability but reduced strength significantly for both aggregate types. Future work will build on these findings to optimize backfill design ranges.

📈 US pushes G20 to fix trade gaps, eyeing China

The United States is urging the G20 nations to address current trade imbalances globally. This call specifically targets the economic dynamics involving China. The US emphasizes the need for fairer trade practices as of recent international discussions. This push comes amid ongoing concerns about global economic stability and fairness. Leaders will continue to discuss these trade issues in upcoming G20 meetings. 📈

⚠️ Zelenskyy: Russian Airspace Is Now Too Dangerous

Ukrainian President Volodymyr Zelenskyy warned that Russian airspace is now completely unsafe for civilian use. He issued this warning on Tuesday, September 1, 2026, to airlines, insurers, and airport users. This comes as intense strikes have continued for over four years since the invasion began. Zelenskyy stated that Ukrainian drones will be present in Russian skies as long as the war persists. However, he noted drones could be cleared for diplomatic purposes upon request. ✈️

✈️ Modi asks Indians to rethink leisure travel abroad

Prime Minister Modi has urged Indian citizens to reduce their leisure travel outside of India. He made this appeal while visiting Kyrgyzstan, emphasizing a focus on domestic tourism. The PM highlighted the need to promote the 'wed in India' initiative across the nation. This call comes as the government pushes for greater internal travel and cultural engagement. He is encouraging people to explore India's diverse landscapes instead of traveling internationally. 🇮🇳

🦟 40+ Health Districts in Tamil Nadu Lack Entomologists

District Entomologist posts remain vacant in over 40 of the 45 Health Unit Districts in Tamil Nadu. The shortage affects crucial vector-borne disease control, especially with dengue cases rising. A total of 48 out of 60 sanctioned Senior Entomologist posts were vacant as of September 2, 2026. This lack of technical manpower risks making vector control activity-driven instead of evidence-driven. The association urged the TNPSC to resolve court issues and fill these posts before the northeast monsoon. 🦟

🔬 NMR signal boost by three orders of magnitude

Researchers demonstrated a new method to significantly enhance the sensitivity of liquid-state NMR using d-DNP. This breakthrough was achieved by using the radical OX063 in high-field NMR settings. The technique yielded 1H signal enhancements of approximately 1000 after liquefaction. This method overcomes previous limitations by preserving liquid-state T2 relaxation time. The applicability of this new hyperpolarization technique was successfully shown for selected amino acids. 🔬

🔭 Black hole stars and microbe cookies are real 🤯

Astronomers identified a new celestial object, a "black hole star," in the early universe. This discovery was made by observing data from the James Webb Space Telescope in 2024. The object, named MoM-BH*-1, is estimated to be about 100 solar masses and is extremely bright. Scientists hope this finding will help solve how supermassive black holes formed quickly after the Big Bang. Separately, microbes are being used to turn plastic bottles into edible cookies called µBites.

🍬 Govt cuts sugar stock limit to curb hoarding

The government halved the sugar stock holding limit for dealers to 2,000 quintals starting September 15 until November 30. This change was implemented across the country to ensure enough availability and stop hoarding. Currently, the limit stood at 4,000 quintals, and the new rule restricts stock holding to 30 days from receipt. This action aims to make the sugar supply chain move smoothly for consumers. The government is also conducting intensive monitoring and physical verification of sugar stocks. 🍬
