The universe is big, but it’s peanuts compared to the eternally inflating multiverse. But just how many universes are there? What are they like? And most importantly, what can they tell us about … aliens?

Some species of bacteria, such as Shewanella and Geobacter can do what other species can’t: They can survive off of solely electrons.

Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just showing off? For better or worse, the physicists are definitely on the right track. We know this because the predictions of quantum field theory stand up to […]

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what’s all this nonsense of extra dimensions?

Spot is an agile mobile robot that you can customize for a wide range of applications. The base platform provides rough-terrain mobility, 360 degree obstacle avoidance, and various levels of navigation, remote control and autonomy. You can customize Spot by adding specialized sensors, software and other payloads. Early customers are already testing Spot to monitor […]

Of all the unlikely ends of the universe, the Big Rip has to be the most spectacular. Galaxies ripped to shreds, dogs and cat first living together, then tragically separated by the infinitely accelerating expansion of space on subatomic scales. Good thing it’s not going to happen. Or is it?

Atlas uses its whole body — legs, arms, torso — to perform a sequence of dynamic maneuvers that form a gymnastic routine. We created the maneuvers using new techniques that streamline the development process. First, an optimization algorithm transforms high-level descriptions of each maneuver into dynamically-feasible reference motions. Then Atlas tracks the motions using a […]

Ants have one of the most complex social organizations in the animal kingdom; they live in structured colonies that contain different types of members who perform specific roles. Sound familiar? Deborah M. Gordon explains the way these incredible creatures mate, communicate and source food, shedding light on how their actions can mimic and inform our […]

Harvard Professor David Sinclair thinks longevity, or extending our lifespan, is the “greatest unsolved problem in biology.” The global life expectancy is currently hovering somewhere around 72 years old and women typically live longer than men and the age tends to be higher in developed countries and lower in impoverished nations. Some experts argue that […]
