Soft devices, powered by ‘stressed’ algae, glow in the dark when squished or stretched

Nature Communications (2022). DOI: 10.1038/s41467-022-31705-6″ width=”800″ height=”530″/> Schematic of the working principle and potential applications of the biohybrid mechanoluminescence. In the light phase, the soft biohybrid robot integrated with dinoflagellate culture solution is charged with sunlight for photosynthesis to produce oxygen, providing energy for the organism. In the dark phase, the mechanically induced bioluminescence of … Read more

Researchers describe the dynamics of cavitation in soft porous material

∞ − psat is applied on the external boundary producing the of the bubble, which is accompanied by the deformation of the solid skeleton. Credit: PNAS Nexus (2022).

An over-pressure ∆p = p∞ − psat is … Read more

Look up this spring and you might see little ravens build soft, cozy nests from your garden trees

Credit: Shutterstock Spring is nearing and birds will soon start nesting in trees in backyards across Australia. The trees in our garden are now 40 years old—not old by tree standards, but old enough to be among the tallest in our suburbs, offering refuge for local native birds. When I propagated Monterey pine (Pinus radiata) … Read more
