Lighter X-ray aprons could spare health care workers from chronic pain

Lighter X-ray aprons could spare health care workers from chronic pain Sadie Harley Scientific Editor Andrew Zinin Lead Editor A light, flexible polymer material developed at the University of Waterloo could replace the lead in heavy X-ray aprons, providing the same protection from harmful radiation while reducing their weight by almost 90%. "For patients who only get X-rays once in a while, heavy lead aprons might be OK, but technicians who wear them every day often develop back and neck...

'EU's environmental policy must be part of defence strategy,' Commissioner Roswall says

The European Environment Commissioner told Euronews that Brussels must "connect the dots" and understand that environmental, economic and security interests go hand-in-hand. The European Union's environmental policy should now be considered a key part of Europe's defence strategy, Jessika Roswall, European Commissioner for Environment, Water Resilience and a Competitive Circular Economy, said. She noted that many of the environmental concerns felt by the bloc, including the impacts of...

Magnon momentum microscopy: A new window into nanoscale spin-wave physics

Magnon momentum microscopy: A new window into nanoscale spin-wave physics Sadie Harley Scientific Editor Robert Egan Associate Editor An international team led by the Max Born Institute has developed a new type of momentum microscopy to image magnons—the quanta of collectively excited spins—directly in two-dimensional reciprocal space using soft X-rays. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and...

Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing

Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing Stephanie Baum Scientific Editor Robert Egan Associate Editor For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate according to the unique and complicated rules of quantum physics.

World’s longest building cost £1.6bn to build and takes 40 minutes to walk across

World’s longest building cost £1.6bn to build and takes 40 minutes to walk across A vast industrial building in California is considered the world’s longest, stretching so far that it takes around 40 minutes to walk its full length A gigantic two-mile-long structure has long been regarded as the world's longest building — and it is so vast that experts say the curvature of the Earth must be taken into account when measuring it. The Klystron Gallery at SLAC National Accelerator Laboratory,...

CT scans of BYD car parts

Design to Reality Evolution of the Plastic Bottle In the dark nights of my soul, I fret about how inconsistently engineered my life is. The coffee table I made a year or two ago was intended to look like the dining room table I built a few years earlier, but in reality the two bear only a vague resemblance to each other. Open a drawer of my tool chest at random, and perhaps you’ll find a thematically-aligned collection of well-loved hand tools, meticulously cut into a nest of Kaizen foam, or...
