The growing flexibility gap Presenteeism has spread online in the digital age;Workers are now almost always available via email, Zoom, and messaging platforms instead of working late at night in the office. But the pandemic’s rise in remote work seems to have widened the trust gap between managers, who can set their own […]

Material matters Using nanoscale, antiferromagnetic materials, Liu’s most recent work at MIT involves building computer memories.Manganese, for example, is an antiferromagnetic material because its ions have electron spin, making them behave like tiny magnets. They arrange themselves so that the magnetism cancels out between ions spinning “up” and those spinning “down.”Antiferromagnetic materials can be packed […]

A resonant problem Marine sonar, aircraft landings, the construction of offshore wind farms, and seismic surveys used in oil and gas exploration are all examples of human-caused ocean noise.However, boats, specifically from their propellers, are the most common source. Cavitation is an effect that occurs when propellers, especially older ones, turn at high speeds. This […]
