A lot can happen in 241 million years. Dinosaurs can rise and fall, and so can the Earth itself. Take Switzerland: In the past 241 million years it went from being beachfront property to a mountainous skier's heaven dotted with chalets.

Childbirth is scary. A tiny human has to somehow emerge from what you thought was a pretty tight space. Some bits of you might literally tear open in the process. You're also almost certainly going to poop in front of strangers.

If at first you don't succeed, try, try again. That should be the motto for a NASA mission that has finally launched after no fewer than 11 scrubbed launch attempts.

For 18 million years, the vast expanses of Earth's largest island (no, Australia doesn't count) have been covered by the aptly-named Greenland Ice Sheet, a colossal mass over two kilometers thick that covers 1.7 million square kilometers. But since 1990, scientists have noticed that the ice—which usually melts in the summer and refreezes in colder months—has been melting faster and earlier in the year. In a recent study published in Science Advances, researchers at the University of Bristol have found an unexpected source of this increased melt: sunlight.

Union County, Florida is 250 square miles, nestled in the middle of the state's pan—not the handle—about an hour southwest of Jacksonville and nearly as far from the state's southern border. Residents depend on four things for their county's survival: farming, trucking, timber, and the state's department of corrections. It is the country's third congressional district, the state's smallest county, and the place in Florida that will take the hardest economic hit from climate change, according to a new study released today in the journal Nature.

Around the world, fires are failing to spark, and grasslands are suffering. Over the past two decades, the amount of burned land has plummeted globally by nearly 25 percent, an international team of scientists reported today. Satellite images indicate that the rise of commercial agriculture is preventing fires from catching hold, especially in grasslands. This might sound like a good thing, but grasslands and their animal denizens actually depend on wildfires. Burned terrain will likely continue to shrink in coming decades, endangering grasslands and savannas as we know them.

Plenty of toys on the market promise to provide the next generation of coders and engineers with the foundation they'll need to compete in the rapidly-changing job market. But in a sea of coding-for-kids products, an update to Anki's holiday-shopping darling, Cozmo the robot, offers a chance for young would-be coders to tap into a complex machine capable of advanced feats, like facial recognition.

The ultimate goal of a lumpectomy is to remove all the cancerous tissue from a person's breast while saving as much of the healthy tissue as possible. But that's even harder than it sounds. Without the ability to look at tissue under a microscope, it's currently impossible to tell whether the area surrounding a tumor contains cancerous cells or not. Surgeons deal with this by taking samples from around the removed tumor, waiting for a pathologist to look at them, and performing additional surgeries if they turn out to be cancerous. This is not only time consuming and expensive, but also extremely stressful for the patient.

Pandas get a lot of attention—and given how hard it is to keep those black and white bundles of fluff from going extinct, it's not surprising that they take up a huge glut of the world's conservation funding. These are animals that literally evolved to be lazy: the only food they eat, bamboo, is incredibly hard for them to digest, so they have to consume about 30 pounds of it a day (around a fifth of that is actually digested) and expend so little energy that they basically live in a state of suspended animation. They also seem to suffer from pretty constant gastrointestinal disorders, and they're notoriously difficult to breed in captivity. Still, we work to save them. In fact, thanks to aggressive conservation efforts from China, the animals moved from "endangered" to "vulnerable" status in 2016.

The biological differences between men and women can affect the way they react to certain drugs and treatments, according to a new study in Nature Communications. If this sounds like a no brainer, you probably haven't looked at many biomedical studies. As PopSci noted earlier this year, biomedical researchers experiment almost exclusively on male animal subjects. A 2011 study found that animals in medical research are up to five times more likely to be male than female.

Ordinary shampoos contain harsh sulfates and chemicals to make lather that strip your hair of its natural oils. WEN by ChazDean doesn't. But it does seem to contain something that makes your hair fall out...so maybe a few sulfates aren't that bad after all?

On May 22, 2020, the largest earthquake ever measured struck off the coast of southern Chile. Once the shaking stopped, Denis García, a resident of the nearby port town Corral, noticed something odd. He was searching for his family, not realizing they were safe and on high ground, when he caught sight of Corral Bay. The waters had drawn back, leaving the seafloor bare. García went to investigate. He did not see the 40-foot-high tsunami barreling toward him until it was too late.
