macOS Tahoe’s new Spotlight clipboard manager leaves plenty of room for powerful third-party apps

The new Spotlight is easily my favorite macOS announcement from WWDC25. It may even be my favorite update across all of Apple’s platforms this year.

The addition of a native clipboard history tool to macOS feels like one of those small but meaningful quality-of-life upgrades we’ve been waiting forever to get. That said… I’m not switching.

Astronomers Just Solved the Mystery of the Universe's Missing Matter

Decades ago, astronomers estimated that “ordinary” matter (basically everything that isn’t dark matter or dark energy) makes up 5% of the universe. There was just one problem—they had no idea where most of it was. Astronomers from the Center for Astrophysics Harvard & Smithsonian (CfA) and the California Institute of Technology (Caltech) have tracked down the universe’s “missing” matter. Fast radio bursts (FRBs) indicate that over three-quarters of ordinary matter, officially called baryonic ma

Scientists achieve 1,000-fold increase in solar electricity using ultra-thin layers

US Streetlights Are Turning Purple

American cities and towns started switching their streetlights from sodium lamps to LEDs about 15 years ago, which changed the color of many nighttime roads from yellowish orange to bright white. But lately an odd new nocturnal color has been spotted across the nation—and the globe. Anecdotal reports of purple-looking streetlights have been popping up since early 2021 in states including Florida, Utah, Texas and Massachusetts, as well as in Canada and Ireland.

I'm a 42-Year-Old Mom and I Tried 18 Products to Finally Sleep Better. These Are the Ones That Worked

Remember when falling asleep was easy? Even well into my 30s, I could simply close my eyes, take a few deep breaths and gently drift off to dreamland. These days, it takes a carefully curated wind-down routine, an army of sleep aids and the mental zen of a shaman for me to fall and stay asleep. Some nights it's because of the rap-tap-tap of my 4-year-old complaining of a bad dream, or the intermittent cries of my 1-year-old. Other times, it's my laundry list of deadlines or to-dos. Or maybe it'

Shaping Light – Volumetric Lighting

As I became more familiar with post-processing over the past few months, I was curious to push those newly learned techniques beyond pure stylization to achieve something more functional. I wanted to find new ways to enrich my 3D work which wouldn't be possible without leveraging effects and passes alongside custom shaders. As it turns out, post-processing is great entrypoint to enhance a 3D scene with atmospheric and lighting effects, allowing for more realistic and dramatic visuals. Because t

Switching to LED lightbulbs saved me hundreds of dollars - but there are 5 other reasons to do it

Vladimir Sukhachev/Getty Images As a kid, I was inspired by the decorative lighting in my grandparents' finished basement. They had festooned the place with multicolored C9 string lights (aka old-school Christmas lights) from wall to wall, beneath the built-in wet bar, around hanging mirrors, and anywhere else they could add an ambient accent for the parties they hosted down there year-round. Since then, I've festooned every home I've lived in with decorative lighting, whether in a sequestered
