How small can a transistor get? (opens the original)
Read excerpt
For decades, engineers have been working to create smaller and smaller transistors to fit ever-larger numbers of them onto computer chips, all in the name of greater processing power. Now, in the age of artificial intelligence (AI), that effort has turned into an all-out race. So how small can a transistor actually get? And is smaller even still the goal? To understand the answer, first you need to know what a transistor is. "If you take a computer or your mobile phone and you were to pry it ope
Which building blocks of life have been found in space, and which haven't? (opens the original)
Read excerpt
Scientists have discovered the basic ingredients for life in asteroids and meteorites, on Mars, and around young stars. All of those findings have come in the past few years, and upcoming missions aim to search for these building blocks of life. But how many building blocks of life have we found in space so far? First, it's important to define what we mean by the building blocks of life. Scientists are looking for molecules that look like those found in life on Earth, including proteins; RNA; an

But being a genius doesn't mean you're infallible. So was Einstein wrong about anything?
