ESA officials said it was only the ninth time an asteroid was spotted before reaching Earth’s atmosphere. And, as the climate changes and summer temperatures linger, educators are increasingly worried about keeping kids safe from heat exhaustion. An Asteroid Impact, Spotted In Advance On Wednesday, an asteroid named 2024 RW1 burned up in the atmosphere above the Philippines. As asteroids go, it was not especially notable. Astronomers say objects the size of 2024 RW1, which was about a meter in diameter, encounter the Earth about every two weeks. Due to local weather conditions, not many ground ..read more

A new study suggests that the asteroid that killed the dinosaurs may have originated from the outer parts of the solar system. And, invasive spotted lanternflies often lay eggs on vehicles and shipped goods. Now researchers are training dogs to sniff them out before they hatch. Asteroid That Killed The Dinosaurs Was A Carbon-Rich Rock Around 66 million years ago, an asteroid slammed into the Earth, blasted debris everywhere, plummeted the planet into cold darkness, and ended the age of dinosaurs. (Though birds survived, of course.) It might be the most famous disaster in our planet’s history ..read more

Eels have fascinated humans for thousands of years, even captivating big thinkers like Aristotle and Freud. Despite having been around for some 200 million years, eels are still rather mysterious creatures. For example, scientists still aren’t sure exactly how they spawn. But those unanswered questions haven’t stopped humans from wanting to eat them. So much so that they’re now endangered in some areas—and a lucrative criminal enterprise has risen up to poach baby eels from the wild. Guest host Rachel Feltman talks with Ellen Ruppel Shell, author of Slippery Beast: A True Crime History, with E ..read more

You might have noticed that the seasons don’t quite behave like they used to. In some places, fall and spring seem to fly by, while winter and summer are much longer and feel more intense. This shift is known as season creep, where the timing of the seasons starts to shift. This phenomenon is mostly due to climate change creating temperature imbalances and throwing weather patterns off kilter year-round. And it can cause problems for plants and animals as their natural cycles fall out of sync. But what does it mean for human behavior? Seasonal Affective Disorder, often called seasonal depressi ..read more

Several states have reported cases of the rare but serious mosquito-borne illness eastern equine encephalitis. And, the new sci-fi movie "Slingshot," about an astronaut’s mental breakdown, prompts questions about how to prepare humans for long-term space travel. Mosquito-Borne Diseases Are Spreading As Temperatures Rise This week, a New Hampshire man died of eastern equine encephalitis (EEE), a rare but extremely serious disease caused by a mosquito-borne virus. Human cases of EEE have also been reported in Wisconsin, New Jersey, Massachusetts, and Vermont, causing some municipalities to step ..read more

According to the Centers for Disease Control and Prevention (CDC), the maternal mortality rate in the United States is very high compared to other wealthy countries: About 22.3 maternal deaths per 100,000 live births. This is on par with China and Iran, based on UNICEF data. So why is the US maternal mortality rate so high? It may have to do with how we fill out death certificates. A study from earlier this year found that misfiling of information in death certificates may be inflating the numbers. The study authors concluded that the US maternal mortality rate was actually half of the CDC-rep ..read more

There’s a phenomenon known as the “overview effect,” a changed perspective some people experience after seeing the Earth from space. Retired astronaut Dr. Cady Coleman says that for her, it was a sense of home and connection. “First of all, I just don’t feel that far away,” she said. “I feel like home is bigger than we thought and I just happened to be the one of the furthest out people. But the overwhelming sort of sentiment that I have is if only everyone knew how connected they could be, there’s literally nothing we couldn’t solve.” Coleman flew on two space shuttle missions, spent 159 days ..read more

Sequoia National Park is largely designated as wilderness. That complicates efforts to protect its iconic trees from worsening wildfires. Also, archaeologists keep finding older and older cave art. Here’s what it could tell us about how humans evolved over time. Protecting Sequoias From Wildfire Raises Tricky Questions Sequoia National Park in California is known for its towering, iconic sequoia trees, some of which are thought to be thousands of years old. Severe wildfires fueled by climate change and a long history of fire suppression have put these trees at risk. One solution to this proble ..read more

A new study measuring microplastics in organs of the recently deceased found that about two dozen brain samples were 0.5% plastic by weight. Also, having an IUD inserted in the uterus is extremely painful for some people. The CDC now recommends that doctors use local anesthetics. Study Finds A Staggering Amount Of Plastic In Human Brains It only takes a quick look at our streets and waterways to be reminded that plastic pollution is a big problem. But that’s just the plastic that we can see. An increasing amount of scientific literature points to microplastics accumulating inside our bodies, p ..read more

It’s been a hot and rainy summer in many parts of the US, and it’s been hard to spend as much time in nature as many of us would like. Heat waves and unpredictable weather have sometimes made it riskier to be outside. Maybe you’ve chosen an easier hike, or doubled up on water bottles, or stayed inside when you’d much rather be outdoors with friends and family. If you’ve been feeling apathetic about the outdoors, a new book called Forest Walking, Discovering the Trees and Woodlands of North America might be a helpful read. Co-authors Peter Wohlleben, a forester and conservation advocate, and Ja ..read more
