A Decoder That Uses Brain Scans to Know What You Mean — Mostly
Scientists have found a way to decode a stream of words in the brain using MRI scans and artificial intelligence. The system reconstructs the gist of what a person hears or imagines, rather than trying to replicate each word, a team reports in the journal Nature Neuroscience. "It's getting at the ideas behind the words, the semantics, the meaning," says Alexander Huth, an author of the study and an assistant professor of neuroscience and computer science at The University of Texas at Austin. This technology can't read minds, though. It only works when a participant is actively cooperating with scientists.

There Are Better Ways to Study That Will Last You a Lifetime
Picture your preschooler’s teacher pulling you aside at pickup time to say that your child was “not taking responsibility” for learning the alphabet. You’d be puzzled and probably angry. It’s not up to a 4-year-old to make sure he learns the alphabet. That’s the teacher’s job. But as your child gets older, he’ll increasingly be expected to teach himself. High school seniors must read difficult books independently, commit information to memory, schedule their work, cope with test anxiety and much more. These demands build slowly across the grades, essentially forming a second, unnoticed curriculum: learning how to learn independently.

Sorry, Weed Probably Does Not Make You More Creative
Many cannabis users are convinced that the drug not only heightens their mood, but also their creativity. Creative luminaries also seem to endorse this idea. Steve Jobs said that marijuana and hashish would make him “relaxed and creative” while astronomer and author Carl Sagan believed that cannabis helps produce “serenity and insight.” In the artistic sphere, Lady Gaga said she smokes “a lot of pot” when writing music, and Louis Armstrong called marijuana “an assistant and friend.” Despite these popular beliefs about the creative potency of cannabis, scientific consensus has remained hazy. Now new research suggests that cannabis may not be a gateway drug to creativity after all.

Experts Say Loneliness Isn’t Just a Social Problem — It’s Bad for Your Health, Too
Loneliness isn't just a social problem — it's a physical problem as well, as scientific research over the past decade has revealed in spades. Research into the topic has found links between social isolation and a variety of physical and mental health conditions, including heart disease, high blood pressure, depression and anxiety. Knowing this, some social critics are asking a once-unthinkable question: should social contact be treated as a basic need, on par with food, water, sleep and shelter?

Presenting Information About Mental Health in a Second Language Could Help Counter Cultural Norms Against Treatment
Bilingual people from cultural backgrounds in which mental health is a taboo topic may be more open to treatment when they hear information in their second language.
