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

Is it a fish? Is it a sea monster? Is it Cthulhu?In 1997, while using underwater microphones to monitor volcanic activity in the depths of the southern Pacific Ocean, researchers with NOAA’s Pacific Marine Environmental Laboratory (PMEL) recorded a mysterious sound. It was extremely loud and, well, weird. The fact that no one, including NOAA, had any idea what was making the noise fed theories like the ones above. The sound came to be called “the bloop” and remained a mystery for more than ...read more

Solar calendar. Place of worship. UFO Landing site. Many uses have been theorized for Stonehenge. Researchers have now added another: monument to unity, they propose in an Archaeology International article.Because the stones making up different aspects of the mysterious structure were moved from many parts of the British Isles, there must have been a reason for it. After all, it’s not the only henge in town. Hundreds of other stone circles have been found in Britain. But almost all of them hav ...read more

The enigmatic idea of dark energy has consistently been referenced to explain the universe’s expansion, but new research may upend years of cosmological beliefs with a shocking claim made by scientists: dark energy doesn’t actually exist.This revelation backpedals on a theory that astrophysicists have commonly followed in the hunt for answers to one of the universe’s most mystifying questions: how its perpetual expansion is possible. The endeavor to understand this concept may need to chan ...read more

NASA’s Parker Solar Probe has now marked itself safe from its closest-ever encounter with the sun.The probe sent a signal just before midnight on Dec. 26, saying it was “alive” and doing fine. This should come as a relief to NASA scientists since communication with the probe “went dark” Christmas Eve when it made its record-breaking closest ever pass — a mere 3.8 million miles from the sun’s surface, according to a NASA blog. That might seem like a big distance, but in the universe ...read more

Centaurs — celestial bodies that combine asteroids’ rockiness and comets’ gaseousness — are relatively rare and short-lived components of our solar system. A team of astronomers has in one of these hybrid objects called Chiron now characterized what could be considered a unicorn among centaurs.Learning About CentaursChiron contains signs that it has emitted both carbon dioxide and methane — the first time the two gasses were found released from a Trans-Neptunian Object (TNO), a team of ...read more

In the United States alone, there were almost 417,000 COVID-19 deaths in 2021. A year afterward, in 2022, there were around 187,000, and a year after that, in 2023, there were about 50,000.The COVID-19 pandemic triggered a massive surge in mortality in the U.S., resulting in reduced life expectancy. But today, life expectancy is recovering, according to the Centers for Disease Control and Prevention (CDC). After dropping to 76.4 years in 2021, it increased by 1.1 years in 2022 (the CDC reported ...read more

Right on time for the surge of holiday travel, a new iteration of the World Magnetic Model (WMM) has just been released, forecasting the future of Earth’s magnetic field. The updated model shows the latest location of the magnetic north pole, which has been gradually shifting toward Siberia over the past decades. What is the World Magnetic Model?The WMM, required to update every five years, follows changes in Earth’s magnetic field. The model provides crucial information for the airline and ...read more
