As the world faces new and often untreatable viral threats, Simon Fraser University researchers have found a way to cut years off the time it takes to discover antiviral drugs. The new research enables scientists to quickly create large libraries of nucleoside analogs (NAs), compounds that mimic the building blocks of DNA and RNA and are widely used to treat cancer and viral infections such as HIV and hepatitis.

Samsung Galaxy Z Fold 8 Ultra Review So Far: One Thing's For Sure, It's Ultra-Expensive

Earlier today, Samsung launched the Galaxy Z Fold 8 Ultra, along with the Fold 8 and the Flip 8. Now, aside from tacking ‘Ultra’ onto the name, the Z Fold 8 Ultra looks and feels a lot like last year’s Z Fold 7. I’ve even put them next to each other, and apart from last year’s much more vivid colorway, I legitimately couldn’t tell the difference between them.

Reusable magnetic invention removes microplastics plus some PFAS from water

Microplastics are an increasing global concern, with growing evidence of their presence in water systems. RMIT University researchers have developed a water treatment material that rapidly removes micro- and nanoplastics and some PFAS (per- and polyfluoroalkyl substances), bringing the technology closer to real-world use. The invention builds on the team's 2022 breakthrough in microplastics removal, extending its performance to much smaller particles and more complex wastewater.

Southwest Airlines' third-quarter forecast falls short as fuel bill climbs

Southwest Airlines reported a more than 9% increase in second-quarter profit from last year as higher fares are increasingly helping the airline cover its fuel tab, but its summer outlook fell below Wall Street forecasts.
