Irna Phillips was a radio voice actor in Chicago when she was asked to create a serialized program. From that, she created a legacy that includes ‘Guiding Light’ and ‘As the World Turns’

The origins of the Stars and Stripes are murky, but generations of Americans have admired stories about Ross creating the first American flag

Most of us know that applying sunscreen is important – we’ve heard it time and time again. Still, on a day-to-day basis, we often rely on our instincts, habits, weather apps, or a generic UV index that doesn’t necessarily say much about what your skin is actually experiencing. The90 Gem is trying to make that exposure a little more personal. It's a sleek, necklace-style tracker that transforms invisible sun exposure into actionable, app-based skincare guidance.Continue ReadingCategory: Wearables, Consumer Tech, TechnologyTags: Sun, Tracking, Health, Fashion, Ultra-violet

In the crystalline waters off Kenya's coast, coral reefs are thriving—evidence of a rare good-news story in the battle to protect oceans from the ravages of climate change.

Growing up in Tahiti, Anna-Bella Failloux saw firsthand the threat posed by mosquitoes: Nearly a third of adults on the picturesque island once had swollen limbs from elephantiasis caused by their bites.

A copper-based compound restored the brain’s ability to clear toxic Alzheimer’s proteins, dramatically reducing amyloid buildup and improving memory in laboratory experiments. The findings point to a potentially fast-tracked new treatment strategy because the drug has already been tested in humans for other neurological conditions.

There are many ways we can keep track of passing seconds. Counting “Mississippi” between numbers works. Monitoring the swing of a pendulum is a little more accurate. Or if you want to get super fancy, use the piezoelectric buzz of electrified quartz.Continue ReadingCategory: Physics, ScienceTags: Atoms, Clock, Nuclear, Time, Mathematics, Atoms

Who would have ever imagined we’d live to see a day where a Ford Escort would boast a better power-to-weight ratio than a Porsche 911? A proper working-class car turned into a sexy rear-wheel-drive, sub-2,000-lb (907-kg), manual sports car that revs to 10,000 rpm!Continue ReadingCategory: Automotive, TransportTags: Ford, Sports Cars, Carbon+Fibre, Custom, restomod

Beneath our feet lie some of the largest living organisms on Earth. Fungi are mostly invisible and largely overlooked, but they help sustain the ecosystems and food systems that we depend on every day.

A new study finds that plants respond to injury by actively redirecting sugars to damaged tissues, helping fuel the regeneration process. Using a fluorescent sensor to track sugar movement in living plants, researchers have discovered that wounds trigger a localized shift in energy transport, concentrating glucose around the injury site. The findings published in PNAS offer new insight into how plants coordinate repair and recovery and could help scientists better understand the mechanisms that support resilience in crops facing physical damage or environmental stress.
