Book explores milestones of astronomical discovery

>>In “Dispatches from Planet 3,” Marcia Bartusiak illuminates overlooked breakthroughs and the people who made them Here’s quick rule of thumb about the universe: Everything old is new again. Those materials being used when new stars or planets form are just recycled cosmic matter, after

Helping computers fill in the gaps between video frames

>>Machine learning system efficiently recognizes activities by observing how objects change in only a few key frames Given only a few frames of a video, humans can usually surmise what is happening and will happen on screen. If we see an early frame of stacked

Smoothing out sketches’ rough edges

>>MIT-developed tool improves automated image vectorization, saving digital artists time and effort Artists may soon have at their disposal a new MIT-developed tool that could help them create digital characters, logos, and other graphics more quickly and easily. Many digital artists rely on image vectorization,

Model can more naturally detect depression in conversations

>>Neural network learns speech patterns that predict depression in clinical interviews To diagnose depression, clinicians interview patients, asking specific questions — about, say, past mental illnesses, lifestyle, and mood — and identify the condition based on the patient’s responses. In recent years, machine learning has been

Air pollution can put a dent in solar power

>>Study finds lost revenue can be millions of dollars annually, suggests ways to quantify haze-related reductions in solar panel output   Ian Marius Peters, now an MIT research scientist, was working on solar energy research in Singapore in 2013 when he encountered an extraordinary cloud

Wireless communication breaks through water-air barrier 

>>In a novel system developed by MIT researchers, underwater sonar signals cause vibrations that can be decoded by an airborne receiver MIT researchers have taken a step toward solving a longstanding challenge with wireless communication: direct data transmission between underwater and airborne devices. Today, underwater

Light from ancient quasars helps confirm quantum entanglement

>>Results are among the strongest evidence yet for “spooky action at a distance” Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in
