Scientists caught a famous “sandwich” molecule in a rare hidden state, uncovering a long-missing step in its formation. For more than 70 years, metallocenes have been among the most important molecules in organometallic chemistry. These compounds feature a metal atom positioned between two carbon-based rings, creating a structure often described as a molecular sandwich. They [...]

A mysterious low-frequency sound known as The Hum has been reported around the world for decades, leaving researchers searching for its source. Imagine lying in bed late at night and hearing a faint engine-like drone that seems to come from somewhere outside. You check the windows, listen for traffic, and search for a nearby machine. [...]

A new MIT-designed lidar chip uses specially engineered antennas to reduce interference and widen the sensor’s field of view. From self-driving cars navigating busy streets to drones surveying disaster zones, lidar has become one of the most important technologies for helping machines perceive the world in three dimensions. By sending out rapid pulses of infrared [...]

Researchers say the isolated white dwarfs Gandalf and Moon-Sized define a new class of stellar remnant because they share five traits, including X-ray emission. Across the immense scale of the Universe, a single unusual object can prompt astronomers to look for others like it, sometimes leading to the recognition of an entirely new class of [...]
