New phononic subsurface designs could help control aircraft turbulence more broadly and predictably without reshaping the vehicle. At cruising speed, a passenger jet can travel around 640 mph while its wings push through turbulent air along their surfaces. That boundary layer turbulence can increase drag, making flight less efficient and requiring more fuel. Mahmoud I. […]

This New Molecule Could Transform How We Recover Gold From Electronic Waste
A new extraction molecule uses electricity to recover metals while sharply reducing the need for chemical reagents. Recovering valuable metals from discarded electronics, mining streams, and industrial waste usually depends on large amounts of chemical reagents. Researchers at the University of Illinois Urbana-Champaign have developed a molecule that could allow electricity to replace much of […]
A Relentless Storm Pattern Is Making Arctic Sea Ice Disappear Faster
A rapid series of low-pressure systems can create weather conditions that make it difficult for ice to recover, affecting Arctic coastlines and the global climate system. Sea ice in the Arctic can recover from a single storm, but repeated cyclones can make that recovery much harder. When several low-pressure systems sweep through the same area […]
