The Global Positioning System (GPS) is a collection of satellites, each containing a powerful and precise atomic clock, that broadcasts their time every 30 seconds. Handheld receivers, like your smartphone, can collect this data and perform calculations to figure out their position on the surface of the Earth.
Transparent biosensors embedded into contact lenses could soon allow doctors and patients to monitor blood glucose levels and a host of other telltale signs of disease without invasive tests.
The Pale Red Dot campaign aimed to find a planet orbiting our nearest stellar neighbour, Proxima Centauri. Incredibly, the quest succeeded and the team did indeed find a planet. Even more excitingly, the planet, Proxima b, falls within the habitable zone of its host star. The newly discovered Proxima b is by far the closest potential abode for alien life.
Where are all the aliens? The universe is too big and too old, why have we not met aliens yet? Do they live in computers? Were they wiped out by an ancient super intelligence? Or are we just to primitive to understand their motives? Whatever the answer is, it is incredibly important for our own future.
The universe is unbelievably big - trillions of stars and even more planets. Soo… there just has to be life out there, right? But where is it? Why don’t we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?
A new map of the human brain could be the most accurate yet, as it combines all sorts of different kinds of data. This might finally solve a century of disagreements over the shapes and positions of different brain areas.
President Obama awards National Medals of Science and National Medals of Technology and Innovation to 17 scientists, engineers, mathematicians and innovators. The National Medal of Science recognizes individuals who have made outstanding contributions to science, engineering and mathematics. The National Medal of Technology and Innovation recognizes those who have made lasting contributions to America’s competitiveness and quality of life and helped strengthen the Nation’s technological workforce.
What may have started as a science fiction speculation—that perhaps the universe as we know it is a computer simulation—has become a serious line of theoretical and experimental investigation among physicists, astrophysicists, and philosophers.
After a decades-long quest, The MIT-Caltech collaboration LIGO Laboratories has detected gravitational waves, opening a new era in our exploration of the universe.
New observations from NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission is providing insight into how Earth is responding to rising levels of heat-trapping gases in the atmosphere, and what this means for our future climate. Earth’s land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it’s uncertain whether the planet can keep this up in the future.
