If you’ve seen an owl fly, you probably didn’t hear a thing. That’s because their skin and feathers dampen sound by absorbing high- and low-frequency flight noise.
Using atomic force microscopy, scientists found that cysteines in collagen IV form bonds that help it resist heat and refold, highlighting a key feature of connective tissue. Researchers at Simon Fraser University (SFU) are gaining new insights into one of collagen’s most puzzling characteristics

CoS-1 is a cobalt zeolite catalyst that boosts propylene production efficiently and stably, challenging platinum-based alternatives.
Propane dehydrogenation is an important industrial method for producing propylene without depending on oil. However, most current processes still depend heavily on precious-metal catalysts like those made with platinum. Finding efficient alternatives that use more common, earth-abundant metals has proven difficult.
