To boost the computing power of artificial intelligence (AI), researchers have combined run-of-the-mill machine learning with a sophisticated 3D model of the human brain made of different types of brain tissue grown in the lab. These miniature models of the brain, known as cerebral organoids or “minibrains,” have existed in various forms since 2013. But … Read more

Big Bang - Deposit Photos

Life has found a home on Earth for around 4 billion years. That’s a significant fraction of the universe’s 13.77 billion-year history. Presumably, if life arose here, it could have appeared anywhere. And for sufficiently broad definitions of life, it might even be possible for life to have appeared mere seconds after the Big Bang. … Read more

Why do common shrews live for only two years, while bowhead whales survive for two centuries? And could the answer give us hints as to how to extend our own, human life spans? The maximum life span of each species is estimated using the age of its longest-living member, and these vary by orders of … Read more

When astronauts return from spacewalks, they often describe unexpected scents similar to burnt steak and spent gunpowder. But why does outer space smell like torched things, and where does this odor come from? To be clear, space is a near-perfect vacuum. While in space, astronauts protect themselves in spacecraft, spacesuits and space stations, “since direct … Read more

High-powered infrared laser weapons could be on the horizon after scientists figured out how to make lasers nine times more powerful. Militaries have already deployed laser-powered weapons, as popularized by films like “Star Wars,”, but they’re much weaker than those seen on screen and can only disable small airborne targets. The light In these current … Read more

Nuclear weapons testing in the 1950s and early 1960s left the first obvious and indelible marks of “overwhelming” human activity on Earth, and these events may signal the beginning of a new geological epoch known as the Anthropocene, geologists say. Fallout from these tests snowed down from the atmosphere and became trapped in the earth … Read more
