For 24 hours a day, seven days a week since November 2000, NASA and its international partners have sustained a continuous human presence in low-Earth orbit, including at least one American – a streak that will soon reach 25 years. When viewed in the history of spaceflight, the International Space Station is perhaps one of humanity’s most amazing accomplishments, a …

A team of researchers has designed an exhaust system that dramatically reduces the extreme heat found inside fusion reactors. For years, scientists have pointed to nuclear fusion’s potential to provide clean and nearly limitless energy. However, one of its biggest challenges is the safe handling of the intense heat from the plasma before it hits the reactor walls. With the …

Stunning microscopic footage has captured the moment a translucent baby sea urchin crawled across a bed of red algae. The video earned fifth place in the annual Nikon Small World in Motion competition. Alvaro Migotto, a zoologist at the University of São Paulo in Brazil, captured the mesmerizing video of the juvenile sea urchin as it moved across its habitat …

Scientists have identified 85 previously unknown lakes hidden beneath Antarctica‘s ice using a decade’s worth of satellite data. The newfound lakes are “active,” meaning they periodically drain and refill, changing size and shape over months and years, the researchers said. This subglacial activity affects the stability of glaciers and their grinding movement over the Antarctic bedrock, which in turn could …

Mammoth species in North America repeatedly interbred over thousands of years, creating hybrid offspring, a new fossil analysis has revealed. The findings alter what we know about the evolution of these Ice Age giants and how they responded to dramatic climate shifts. It has generally been assumed that the woolly mammoth (Mammuthus primigenius), which lived in what is now Canada …

Optical tweezer arrays 1,2 have transformed atomic and molecular physics, now forming the backbone for a range of leading experiments in quantum computing 3–8, simulation 1,9–12, and metrology 13–15. Typical experiments trap tens to hundreds of atomic qubits, and recently systems with around one thousand atoms were realized without defining qubits or demonstrating coherent control 16–18. However, scaling to thousands …
