During 2024, I ...read more

Some of the most stunning and spectacular sites on the planet are waterfalls. Not only are they beautiful, but these natural water breaks can have cultural significance, help shape landscapes, create microclimates, and even be used as a source of hydroelectricity. The tallest waterfalls on the planet can reach heights of over 1,000 feet, with millions of gallons of water spilling over them. And while the tallest waterfall on land is Angel Falls in Venezuela, which stands at 3,212 feet tall, the ...read more

Back in 1998, astronomers made a curious discovery. By studying the behavior of distant supernovas, they concluded that the universe is not just expanding, but that this expansion is accelerating. The cosmos, they concluded, is exploding. The discovery rocked cosmology. It implied that the universe would probably experience a long cold death as its components raced inexorably away from each other. It also raised the question of what was causing this acceleration. Cosmologists eventually decided ...read more

The current eruption at Kīlauea in Hawai'i that started just before Christmas is still rolling along. The activity from the major vents on the edge of the Halema'uma'u crater has waxed and waned some, but lava fountains reaching tens of meters (hundreds of feet) have been common for the past week. The USGS Hawaii Volcano Observatory reports that lava from this eruption has covered two-thirds of the caldera floor. An overflight of the volcano on December 27 showed the extent of the new, dark, bl ...read more

When I conceived the idea for this column in 2013, I came up with the name "ImaGeo" as a mashup of "image" and "geo" — as in "images of Earth." (The mashup also hinted at "imagination.")Since then, I've tried whenever possible to emphasize images of Earth from space, as well as imagery created with data from other kinds of sensors. With that original ImaGeo theme in mind as 2024 was drawing to a close, I thought I would pick a selection of compelling images that helped me tell the stories of n ...read more

Lining grocery store shelves are supplements like omega fish oil, goat’s rue and others that sound more like the ingredients of a witch’s cauldron. Social media influencers also push high-tech sounding pills like CoQ10 or plant sterols to their followers. And you can find the classic supplements online or in person — vitamin D, vitamin C or a daily multivitamin.In the United States, the supplement market was estimated to be worth $42.6 billion in 2022, and it was projected to increase up t ...read more

At one time, the world of non-alcoholic drinks was limited to a few dusty old cans of O’Doul’s sitting in the back fridge of your local bar.But more recently, the genre has exploded. Craft beer companies are bending the basic tenets of chemistry in an effort to make non-alcoholic IPAs, stouts, and other styles that more closely resemble their boozy cousins.And restaurants are crafting mocktails that focus on flavor specifically tailored to a lack of alcohol. All of this comes at a time when ...read more
