The mission of a lifetime: a drone on Titan in 2034 (Update)

Elizabeth Turtle was overjoyed when, on June 26, she received a call from NASA: her project to send a drone quadcopter to Titan, Saturn's largest moon, was given the green light, which came with a budget of nearly a billion ...

Did comet impacts jump-start life on Earth?

Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly ...

Getting a big look at tiny particles

At the turn of the 20th century, scientists discovered that atoms were composed of smaller particles. They found that inside each atom, negatively charged electrons orbit a nucleus made of positively charged protons and neutral ...

Scientist sheds light on Titan's mysterious atmosphere

A new Southwest Research Institute study tackles one of the greatest mysteries about Titan, one of Saturn's moons: the origin of its thick, nitrogen-rich atmosphere. The study posits that one key to Titan's mysterious atmosphere ...

Oxygen migration at the heterostructure interface

NUS physicists have developed a methodology to control the electromigration of oxygen atoms in the buried interfaces of complex oxide materials for constructing high mobility oxide heterostructures.

Understanding the building blocks for an electronic brain

Computer bits are binary, with a value of zero or one. By contrast, neurons in the brain can have many internal states, depending on the input that they receive. This allows the brain to process information in a more energy-efficient ...

Cassini's final view of Titan's northern lakes and seas

During NASA's Cassini mission's final distant encounter with Saturn's giant moon Titan, the spacecraft captured the enigmatic moon's north polar landscape of lakes and seas, which are filled with liquid methane and ethane.
