Concrete can perform just as well if three-quarters of its content has been recycled, a team has found.
Concrete is made from granular materials such as sand and crushed stone – known as aggregates – bound together by a cement paste. Cement has a high carbon footprint due to the chemistry of its production and the high processing temperatures, while the aggregates have a high ‘resources footprint’ because they come from finite natural sources. With global construction rates predicted to rise by 35% by 2030, researchers are looking for ways to reduce both footprints through recycling or using other materials.
A team led by Italian engineers has refined the processing of demolition waste on site and tested ways of using the resulting streams of powders and aggregates in fresh concrete.

A technology for building quantum computers that has long been discarded by large corporations is gaining momentum. As quantum computers have transformed from academic practice to big business over the past decade, the spotlight has been mainly on one approach: the tiny superconducting loops being embraced by technology giants such as IBM and Intel. Thanks to superconductors, Google was able to claim last year that it had achieved “quantum advantage” with a quantum machine that for the first time performed a certain calculation beyond the practical capabilities of the best classic computer. But a separate approach, using ions trapped in electric fields, is gaining momentum in the search for a commercial quantum computer.

When Beny Falkovich leaves his home in Boston for a much-anticipated trip home to Israel this upcoming March, he will see his family and friends after many long months. But there’s another thing Falkovich hopes to accomplish on his trip: to roll up his sleeve and get vaccinated against COVID-19.
As Israel races ahead of the rest of the world with more than 2.5 million people receiving their first vaccination, some Israelis who live abroad are eyeing the possibility of combining a trip home with a coronavirus vaccination that may not be available for months in their new home countries.
