Humans work together on enormous scales to build complex tools as large as cities and create social networks that span the globe. What is the key to our success? This …
After a storied career with 5 spaceflights (including three trips to fix the Hubble Space Telescope), NASA astronaut John Grunsfeld now helms the space agency’s scientific missions. He helps shepherd …
The prestigious biennial Kavli Prizes recognize scientists for major advances in three research areas: astrophysics, nanoscience and neuroscience—the big, the small and the complex. The 2014 winners, sharing a $1 million award in each field, will be announced live via satellite from the Norwegian Academy of Science and Letters in Oslo.
Extra dimensions of space — the idea that we are immersed in hyperspace — may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still — but ultimately hit a dead end.
What made Albert Einstein one of the greatest scientific geniuses the world has ever known? His scientific breakthroughs revolutionized the way we understand the universe.
Imagine beating every strain of flu with a single jab. Wiping out your risk of some lethal cancers, HIV, and Ebola during a routine doctor’s visit. That’s the promise of next-generation vaccines, and researchers are closing in on the basic science needed to bring them to reality.
Are we alone? It’s a question that has obsessed us for centuries, and now we have the technology to do more than wonder. Scientists on the hunt for distant planets and extraterrestrial intelligence explore faraway galaxies and barely visible realms.
