Nausea. Severe abdominal pain. Compulsive bathing. These are some of the hallmarks of cannabinoid hyperemesis syndrome, a medical condition that’s on the rise. This gastrointestinal condition stems from frequent, long-term marijuana use, but what's behind the recent surge in cases?

Ready to be entertained? We can help with that! Here's everything you need to know about gladiators.

Fifty years ago, humans sent a message into space to introduce ourselves to potential alien life. Since then, the Arecibo Observatory—our only tool for sending such messages—has collapsed, taking with it our ability to respond if anyone answers. Learn more about the Arecibo Message and its lasting impact at the link in bio.

Scientists are celebrating an adorable and remarkably well-preserved discovery—a 32,000-year-old sabertooth cub. Mummified in the Siberian permafrost, this baby apex predator is almost perfectly intact, right down to its reddish fur. It's the first time scientists have gotten a true look at what these ancient animals looked like, as past findings only included bones and footprints.

Photos by danwintersphoto | At Starbase in Boca Chica, Texas, SpaceX launched flight six of Starship—a combined 400-foot vehicle—at 4 p.m. central time on Tuesday, November 19, 2024. SpaceX was hoping to replicate the October 13 Starship launch, when the Mechazilla tower caught the Super Heavy Booster upon its descent back to terra firma. Although the booster this time went to its default trajectory with a “landing burn and soft splashdown in the Gulf of Mexico,” according to SpaceX, each launch provides valuable data for future flights. Starship’s upper stage continued to coast through space toward a successful soft splashdown in the Indian Ocean at about 5:05 p.m. central time. Each attempt puts us one step closer to landing humans again on the lunar surface. NASA intends to use a modified version of Starship to take astronauts down to the moon’s surface as part of the planned Artemis III mission that will launch from Kennedy Space Center in Florida before 2030. Follow me at danwintersphoto for continuing coverage of NASA’s Artemis program. 1. This is the moment of ignition. 2. A SpaceX helicopter surveys the launch area. 3. Starship enters its roll program. 4. The skyward climb is under way. 5. Starship’s rise through the upper atmosphere creates a vapor cloud. 6.

National Geographic photographers ventured to places far and wide to capture the year’s most fascinating images. Out of more than 2.3 million photos, 20 were selected as our Pictures of the Year. See them all at the link in bio. 📸 1 - Robbie Shone (shonephoto) photographed researchers—joined by a bat—in Gabon’s Bongolo Cave. They’re creating a record of past rainfall by analyzing stalagmites, calcium carbonate formations created by water dripping over thousands of years onto the cave floor. The Western African Paleoclimate Project’s goal is to understand the climate threats to agriculture across the region. 📸 2 - Jason Gulley (jason_gulley_science) documented snook and mullet darting between the dark, tannic Suwannee River and the clear Fanning Spring, one of a thousand freshwater springs in Florida. A late winter flood caused the colder, denser river water to creep under the warmer water in the channel connecting the spring to the river. 📸 3 - jasperdoest photographed Constantin Dăncilă in a traditional sheepskin coat. Dăncilă is intimately familiar with the Romanian land his family has worked for a century and has seen significant changes in the environment, prompting him to adapt his farming practices. With less snow in winter to supply streams, grass in the valley has become scarce, so he drives his flock higher into the alpine meadows.

Said to be one of the strongest wooden ships of its day, the Endurance was the perfect vessel for Ernest Shackleton’s adventure. But at 5 p.m. on November 21, 1915, the crew, encamped on an ice floe and watching in horror, spotted the stern rise into the air. “She’s gone, boys,” was all Shackleton could muster as the ship slid down to her frigid grave. In the above images, photographer Frank Hurley documented the Endurance’s final days and the crew’s incredible journey of survival. No one ever expected to see the stout little ship again. Until its incredible discovery in 2022. Uncover the story in #EnduranceFilm, now streaming on DisneyPlus and hulu.

Over the last year, our photographers documented stories across every continent. With more than 2.3 million images captured, we selected the 20 most compelling to feature in our Pictures of the Year 2024. 📸 From 50-foot penguin cliff jumps and elusive tigers to volcano eruptions and an eclipse, view these and other special moments featuring rare wildlife, scientific discoveries, and human exploration at the link in bio.

Do you look like your dog? According to new research, it’s common for dogs and their owners to share striking similarities—not just in terms of appearance, but also temperament and personality. In fact, these similarities actually deepen over time. But what explains this connection? Learn more at the link in bio. Photographs by Gerrard Gethings (gezgethings)
