Galen Buckwalter, a 69-year-old research psychologist and quadriplegic, participated in a brain implant study to contribute to science that aids those with paralysis. The six chips in his brain decode movement intention, allowing him to operate a computer and feel sensations in his fingers again.

For most of human history, night arrived as a planetary certainty. Darkness spread across landscapes, and the sky revealed thousands of stars. Today, that sky is disappearing. Artificial light spills upward from cities, scattering through the atmosphere and turning night into a permanent haze. Research mapping global sky brightness shows that more than 80 percent of humanity now lives under light-polluted skies, and the Milky Way has vanished from view for over a third of the world's population.

Our eyes—which we usually think of as purely visual organs—spontaneously dance to the rhythm of what we hear, says study co-author Du Yi, a cognitive neuroscientist at the Chinese Academy of Sciences in Beijing. Using a high-speed eye-tracking system, Du and her team were stunned to discover nonmusicians instinctively blinking in sync with the beat structure of Bach chorales.

The design of classrooms, childcare facilities, community centers, and public spaces directly shapes how sound is perceived, how communication unfolds, and how inclusion is experienced. Acoustics, spatial configuration, lighting strategies, and material choices can either reinforce barriers to participation or foster environments that support diverse auditory experiences.

I'm very sensitive to sound, so the smallest noises can be distracting. Silence is sometimes loud for me. After the diagnosis, Sussman's parents switched him to a school that specialized in helping students with learning differences. His mom also started playing brown noise to help him relax or fall asleep, after she read that low-frequency (lo-fi), deep rumbling sounds-like heavy machinery or strong rainfall-can soothe those with ADHD.

I didn't want to get hearing devices because, to me, there was a horrible stigma. People who wore hearing aids were doddering. They didn't listen, they said, 'what, what,' over and over. Worse, the hearing aid would make this squealing sound. I worried that it was the beginning of the end of me.

The sound stopped suddenly. I wanted to use my right foot to hit the drum twice, but I ended with the first try. At that instant, my brain really drew a blank. I thought, 'What's going on?' This was Yamaguchi's recollection of the first symptoms of musician's dystonia that appeared during a concert in 2009, marking the beginning of his five-year journey to diagnosis.

When professionals talk about how to remove background noise from video, they are really talking about improving the audio track of a video so the speaker's voice is clearer, more consistent, and easier to understand. Background noise refers to any unwanted sound that competes with the main voice, like air conditioning hum, office chatter, keyboard typing, traffic, or the low hiss created by recording equipment and compression. In video production, background noise removal is about reducing distractions so the listener can focus on the message.

But what you have the right to do is not always the action that will lead to the most happiness for you. In fact, if you insist upon escalating before exploring a gentler approach, you will often make things worse. So your wife isn't entirely full of it. Tense relationships with neighbors really do make a lot of people miserable, and it makes sense that she'd want to avoid pissing off people who live within shouting distance and are apparently pretty combative.

In today's fast-paced world, stress and anxiety have become constant companions for many of us. It may feel impossible to get out from under our fears, worries, and other distressing thoughts. That's why learning how to get grounded is so important. Keep reading to discover seven quick and easy grounding techniques to reduce anxiety and help you enjoy a more peaceful, joyful life.

It makes sense, right? Every day, we're told how shitty our attention spans are because of our phones. We can't get through 90-minute movies anymore without a quick scroll. We can't just sit down and read a book off our shelf. We have decision fatigue trying to pick a recipe to cook instead of just looking in a cookbook. So turning to more analog things for the betterment of our bodies and minds makes total sense.

Wooden spoons as microphones, siblings spinning in socks across the floor, a mother laughing as Whitney Houston's "I Wanna Dance With Somebody" fills the room for the third time in a row-this is love. Long before children understand romance, they learn connection this way, through synchronized movement, shared joy, and the safety of familiar songs. Research on rhythm and social bonding suggests that moving in time together can regulate the nervous system and strengthen feelings of connection.

When Matt Hillier was in his 20s, he went camping with a friend who was a nurse. In the morning she told him she had been shocked by the snoring coming from his tent. She basically said, For a 25-year-old non-smoker who's quite skinny, you snore pretty loudly,' says Hiller, now 32. The Guardian's journalism is independent.

They're called open earbuds (or open-ear buds, depending on the brand), and just about every audio brand has a pair (or three). They come in a slew of styles, but most either loop around your ears like older Beats buds, or clip on like funky-futuristic earrings. Whatever the style, they're designed to deliver satisfying sound while keeping your ear canals open to the sounds of the world around you.

Previous research has shown that people feel better in bird-rich environments, but Christoph Randler, from the University of Tubingen, and colleagues wanted to see if that warm fuzzy feeling translated into measurable physiological changes. They rigged up a park with loudspeakers playing the songs of rare birds and measured the blood pressure, heart rate and cortisol levels (a marker of stress) of volunteers before and after taking a 30-minute walk through the park.
