When plant roots learned to follow gravity

Highly developed seed plants evolved deep root systems that are able to sense Earth's gravity. The how and when of this evolutionary step has, until now, remained unknown. Plant biologists at the Institute of Science and ...

'Unprecedented' discovery of unique infrared light signature on Neptune's moon Triton

Triton orbits Neptune, the eighth planet from the Sun, some 2.7 billion miles from Earth—at the cold outer fringe of the Solar System's major planet zone. Surface temperatures hover near absolute zero, so low that common ...

Scientists discover new chemistry that may help explain the origins of cellular life

Before life began on Earth, the environment likely contained a massive number of chemicals that reacted with each other more or less randomly, and it is unclear how the complexity of cells could have emerged from such chemical ...
