Pacific Grove, California--Pop a few human stem cells into culture, provide the right molecular signals, and before long a mock cerebral cortex or a cerebellum knockoff could be floating in the medium. These neural, or brain, organoids, typically just a few millimeters across, are not "brains in a dish," as some journalists have described them. But they are becoming ever more sophisticated and true to life, capturing more of the brain's cellular and structural intricacy. "It's surprising how far this [area] has advanced in the last year," says John Evans, a sociologist at the University of California San Diego who follows the research and public opinions on it. That progress has allowed researchers to delve deeper into how the human brain develops, functions, and goes awry in diseases, but it has also sharpened ethical questions.

Technology The U.S. Mint is auctioning the last pennies--and they could sell for millions Breakthroughs, discoveries, and DIY tips sent every weekday. In everyday transactions, a one cent penny is worth exactly its face value. But as any coin collector knows, some pennies are worth more than others. For example, a single mint-condition 1909 Lincoln wheat penny is currently valued at around $21, while an even rarer "Indian Head" penny from 1859 can sell for as much as $986. While it's unclear how much the very last pennies ever produced are worth, purchasing them at an upcoming auction will undoubtedly cost much more than pocket change.

By analyzing the unique properties and behaviors of backdoor attacks, we formulate trigger restoration as an optimization problem and design a novel metric to detect back-doored policies.

A 26-year-old woman is in critical condition after a man poured a liquid on her and set her on fire during an argument on a Chicago Transit Authority train, police said.

Science Biology Humans sync their blinks and brain waves to a song's beat Our bodies react to music whether we want it to our not. Breakthroughs, discoveries, and DIY tips sent every weekday. A good song can easily get a listener nodding their head or tapping their foot along to the beat. While you may not initially realize you're doing it, those physical responses to music are still conscious decisions that you can stop whenever you want. According to neuroscientists, however, music also has the ability to influence even some of our involuntary movements.
