Stone Tools From India: Another Blow To Human Evolution Model?

Posted on Categories Discover Magazine

A new study on stone tools from a site in India offers the latest challenge to the model of human evolution and migration that has dominated paleoanthropology, particularly in the West, for decades. The artifacts, which the researchers say were produced with a sophisticated style of tool-making, are hundreds of thousands of years older than might be expected. What does it mean? Well, that part of the story is still up for debate. At the archaeological site of Attirampa ...read more

"Hello!" says the human. "Hello!" pipes the orca right back. It's not a children's movie, but an actual orca emitting human(ish) words.

Speech Recognition Tech Falls Prey to Secret Messages

Posted on Categories Discover Magazine

You hear one thing, but the computer hears another. What's going on here? Two researchers from the University of California, Berkeley have exploited the technique computers use to decode human speech to hide messages inside snippets of audio. When translated by a speech recognition program like Mozilla's DeepSpeech, the computer ends up transcribing the hidden message instead of the sounds we hear. Do You Hear What I Hear? The method basically involves hiding a quiet sample of the audio ...read more

The Melded Minds of Best Friends

Good friends like to think they're on the same wavelength. They aren't wrong. Besties laugh at the same jokes, like the same movies and hate the same people. And underlying all these likes and dislikes, close friends also share strikingly similar neural activity while thinking about them. Researchers at Dartmouth College analyzed brain scans of close friends and found that their brains tend to respond to the world in similar ways. As a next step, researchers want to see if it's possibl ...read more
