“One of the biggest roadblocks to generating functional tissue replacements has been our inability to print the complex vasculature that can supply nutrients to densely populated tissues,” said Jordan Miller, assistant professor at Rice University in the US.

“Further, our organs actually contain independent vascular networks — like the airways and blood vessels of the lung or the bile ducts and blood vessels in the liver,” Miller said.

“These interpenetrating networks are physically and biochemically entangled, and the architecture itself is intimately related to tissue function. Ours is the first bioprinting technology that addresses the challenge of multi vascularisation in a direct and comprehensive way,” he said.

A cataclysmic collision between a pair of dead stars may have seeded our solar system with precious heavy metals including gold and uranium, according to a newly published study. If such an event were to be observed in the present day, it would be the brightest point in the night sky.

BAE Systems has made aviation history by maneuvering the first aircraft in flight using supersonically blown air instead of ailerons or other control surfaces. Taking to the skies over Wales, the wing-shaped Magma UAV makes use of two new technologies that could revolutionize aircraft design.

Lightning strikes can more than double some mushroom crops, according to ongoing experiments that are jolting fungi with electricity.

Bird populations across the French countryside have fallen by a third over the last decade and a half, researchers have said.

Dozens of species have seen their numbers decline, in some cases by two-thirds, the scientists said in a pair of studies – one national in scope and the other covering a large agricultural region in central France.

“The situation is catastrophic,” said Benoit Fontaine, a conservation biologist at France’s National Museum of Natural History and co-author of one of the studies.

Thankfully, it’s unlikely the solar array could be weaponized into an orbiting “death ray”.

Matter waves constitute a crucial feature of quantum mechanics, in which particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated in 1924 by the French physicist Louis de Broglie. The existence of the wave property of matter has been successfully demonstrated in a number of experiments with electrons and neutrons, as well as with more complex matter, up to large molecules.

For antimatter, the wave-particle duality has also been proven through diffraction experiments. However, researchers of the QUPLAS collaboration have now established wave behavior in a single positron (antiparticle to the electron) interference experiment. The results are reported in Science Advances.

The QUPLAS scientific collaboration includes researchers from the University of Bern and from the University and Politecnico of Milano. To demonstrate the wave duality of single positrons, they performed measurements with a setup similar to the so-called double-slit experiment. This setup was suggested by physicists including Albert Einstein and Richard Feynman; it is often used in quantum theory to demonstrate the wave nature of particles.
