Researchers Claire Rind and Luke Birkett discovered tarantulas shoot silk from their feet when they lose their footing. The silk is produced by microscopic spigots on the spiders' feet, which are distributed across the foot's surface.
The exhibition features 48 works chosen from over 200 submissions, highlighting the aesthetic value of scientific images. The online gallery allows public voting for the 'people's choice' award, with cash prizes awarded to top three entrants.
The new microscope uses aberration-correction technology to form color images uniquely identifying individual atoms in a crystal and showing how they bond. It allows scientists to analyze materials at the atomic scale, enabling better development of new materials for electronic circuits and nanoscale devices.
The new STEM allows for color pictures of individual atoms, revealing bonding between them and material properties. It also increases imaging speed by a hundredfold, enabling scientists to analyze structures at the atomic scale.
The new microscope enables crystallographic information to be measured at a lateral resolution of about 40 cubic nanometres, and depending on the material, even more finely. Researchers have already used it to study steel-related iron-aluminium intermetallic alloys, which show promise for high-temperature gas turbines.
Researchers developed an Interactive Scanning Electron Microscope (iSEM) system to simulate the capabilities of a $200,000 analytical instrument in classrooms. Students can measure and analyze objects in detail, simulating real-world experiments previously only accessible to graduate students.
