Philistines had a taste for far-flung foods, fossilized tooth plaque reveals

Researchers have long agreed that the New Testament tale of the Three Wise Men reflects a thriving long-distance trade that brought exotic oils and resins from the Arabian Sea and points further east into the Mediterranean region in Roman times. But a surprising new discovery is revealing that ancient residents of what is today Israel were enjoying south Asian fruits and spices as early as 3,500 years ago.

Here s how neuroscience can protect AI from cyberattacks

Here’s how neuroscience can protect AI from cyberattacks Shares Deep learning has come a long way since the days it could only recognize hand-written characters on checks and envelopes. Today, deep neural networks have become a key component of many computer vision applications, from photo and video editors to medical software and self-driving cars. Roughly fashioned after the structure of the brain, neural networks have come closer to seeing the world as we humans do. But they still have a long way to go and make mistakes in situations that humans would never err. These situations, generally known as adversarial examples, change the behavior of an AI model in befuddling ways. Adversarial machine learning is one of the greatest challenges of current artificial intelligence systems. They can lead machine learning models failing in unpredictable ways or becoming vulnerable to cyberattacks.
