Dutch scientists pipe office urine into bacteria-filled cells that generate electricity and recover nitrogen and phosphorus, while a related system can produce hydrogen
Meet Rachel Chen, the 18-year-old Los Angeles student who expanded a 1997 quantum-math idea to describe entire particle systems with simple diagrams; she won $100,000
In 2018, scientists seeded clouds over China's Muz Taw Glacier to make snow; the brighter surface was followed by 14% to 17% less ice loss in a preliminary experiment
All known life uses 4 DNA letters; UC San Diego showed an existing bacterial enzyme can accurately read and transcribe 8, doubling the genetic alphabet with synthetic letters
Scientists covered 200 square metres of a Swiss glacier with sheep’s wool; early tests found it protected the ice about as well as plastic sheets, but only 0.02% of Swiss glacier ice is covered
What if your ‘lizard brain’ never existed? Scientists challenge a 70-year-old theory and uncover the wiring battle that may have shaped human intelligence
Scientists reconstructed a Wyoming forest from 56-million-year-old fossil leaves; it lost about 60% of its canopy during ancient warming and took more than 100,000 years to recover
In 1996, Columbia scientists shifted Biosphere 2’s 2.6-million-gallon Arizona ocean between ice age, modern and future CO₂ every 3 months; future chemistry cut coral calcification by about 40%
In 1879, Edwin Hall discovered an electrical effect thought to need a perpendicular magnetic field; 147 years later, scientists have shown it can work with the field in-plane
