Lost tombs and quarries rediscovered on British military base in Cyprus      (via sciencedaily.com)     Original source 

Archaeologists rediscovers 46 sites at the Eastern Sovereign Base Area at Dhekelia, Cyprus. Archaeologists located sites from archive records, a number of which were thought to have been 'lost.' They uncovered evidence of quarries and tombs likely to span from the Bronze Age, Byzantine, Hellenistic and Roman periods.

Harmful 'forever chemicals' removed from water with new electrocatalysis method      (via sciencedaily.com)     Original source 

Scientists have developed new electrochemical approaches to clean up pollution from 'forever chemicals' found in clothing, food packaging, firefighting foams, and a wide array of other products. A new study describes nanocatalysts developed to remediate per- and polyfluoroalkyl substances, known as PFAS.

Evolution-capable AI promotes green hydrogen production using more abundant chemical elements      (via sciencedaily.com)     Original source 

A research team has developed an AI technique capable of expediting the identification of materials with desirable characteristics. Using this technique, the team was able to discover high-performance water electrolyzer electrode materials free of platinum-group elements -- substances previously thought to be indispensable in water electrolysis. These materials may be used to reduce the cost of large-scale production of green hydrogen -- a next-generation energy source.

Researchers create coating solution for safer food storage      (via sciencedaily.com)     Original source 

Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say.

It's not only opposites that attract -- new study shows like-charged particles can come together      (via sciencedaily.com)     Original source 

A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range, depending on the solvent and the sign of the charge. The study has immediate implications for processes that involve interactions in solution across various length-scales, including self-assembly, crystallization, and phase separation.

Better neutron mirrors can reveal the inner secrets of matter      (via sciencedaily.com)     Original source 

Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the ESS. The improved mirror has been developed by coating a silicon plate with extremely thin layers of iron and silicon mixed with boron carbide.

Researchers improve the stability of perovskite solar cells      (via sciencedaily.com)     Original source 

Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.

Slimming down a colossal fossil whale      (via sciencedaily.com)     Original source 

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

A bright idea for recycling rare-earth phosphors from used fluorescent bulbs      (via sciencedaily.com)     Original source 

Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.

Experiment captures why pottery forms are culturally distinct      (via sciencedaily.com)     Original source 

Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.
