Nobody likes hearing their neighbors' music or loud conversations. Soundproof wall materials, however, can be quite expensive. Swedish scientists have developed a thinner, less costly alternative, in the form of a spring-loaded sound-damping screw.

When someone is suffering from a deep stab wound, it's important to apply pressure within that wound. A new student-designed device is intended to let first responders do just that, potentially saving lives that might otherwise be lost.

Ordinarily, if you're building something, you don't want the materials to buckle under pressure. In a new Harvard University-designed system, however, that buckling action allows flat-packed objects to be twisted into useful three-dimensional forms.

As part of a refurbishment at the planetarium at La Coupole, a former World War Two bunker in northern France that's now a museum, RSA Cosmos has installed a dozen 4K projectors to create what's billed as the world's first 10K 3D planetarium.
