4 Days Ago   Ancient farmers and hunter-gatherers living thousands of years ago in today’s Romania had sex, according to a new study. The finding adds to our understanding of how different groups of ancient humans interacted with each other — painting a more nuanced picture of how farming spread across Europe.

5 Days Ago   I don’t like going to hospitals. I’m always wondering about what kind of bacteria are floating around and what pathogens I’m going to pick up. Well, my abstract fears have just gotten a little bit more real.

7 Days Ago   Our spinal column is different from that of apes because — yes, you guessed that right — we walk upright on two feet. But when did our distinctive back structure first evolve?

10 Days Ago   The seed bank designed to preserve the world’s crops and plants in the event of global disaster isn’t prepared to withstand the greatest global disaster facing our planet: global warming.

10 Days Ago   I might sound stereotypical as hell here, but I’m Italian and I care a lot about food. I also think Italian food is the best food in the world, and I get mad if you bastardize Italian dishes with ingredients that have nothing to do with it.

12 Days Ago   In 2012, a Time magazine cover showing a 3-year-old kid breastfeeding caused a ruckus. Well, that photo would have been just fine in the orangutan world: young orangutans keep nursing for 8 years or more — longer than any other mammal, according to a new study.

12 Days Ago   Four thousand feet above sea level in Hawaii’s Kokeʻe State Park, the weather is drier and cooler than the island of Kauaʻi below. Unlike the lowland, where invasive species dominate the landscape, there’s a forest of mostly native trees and plants all around us.

13 Days Ago   If you wonder where your plastic toothbrushes and cigarette lighters go after you trash them, here’s your answer: many end up in the ocean, which means that they either sink to the bottom or wash up on beaches — like this remote, uninhabited island in the middle of the Pacific Ocean.

14 Days Ago   Diesel cars, trucks, and other vehicles in more than 10 countries around the world produce 50 percent more nitrogen oxide emissions than lab tests show, according to a new study.

17 Days Ago   While I’ve been to several national and state parks around the US, I’ve never visited a national marine sanctuary — protected areas off the US coasts and in the Great Lakes.

18 Days Ago   Scientists have found a new species of whale ancestor — a toothy cetacean that sucked prey into its mouth and likely hunted at the bottom of the seafloor.

19 Days Ago   For the first time since President Donald Trump took office, Republicans voted down a resolution to repeal a rule passed under President Barack Obama. In a 51 to 49 vote, the Senate rejected an effort to strike down an environmental regulation aimed at limiting methane emissions from oil and gas drilling on public lands.

19 Days Ago   Scientists have developed a new system that allows people with no coding experience to teach robots simple tasks, such as grabbing an object and dropping it into a bucket.

20 Days Ago   Two years ago, scientists announced the discovery of a puzzling new species of early human: Homo naledi. The 15 partial skeletons were uncovered deep inside a cave in South Africa — and featured human-like hands and feet, but surprisingly small brains the size of a gorilla's (a third the size of modern human's).

31 Days Ago   President Donald Trump just signed an executive order aimed at expanding offshore oil and gas drilling in the Arctic and Atlantic Oceans — and maybe even in the Pacific Ocean.

32 Days Ago   Scientists found DNA from ancient humans in the soil of caves — even when there were no bones uncovered at the site. The research shows that, even when no fossils are around, sediments inside caves can tell us which early humans were present where and when.

34 Days Ago   Hundreds of different dog breeds exist today — one for everyone’s taste. I love big dogs like German Shepherds and Goldendoodles, but I’m not a big fan of Chihuahuas and Shih Tzus.

36 Days Ago   Birds look mean, you can’t pet them, and they shit on you. Maybe I loathe them because I’ve lived in cities my whole life, and my few interactions with birds consist of the following: pigeons (aka rats with wings) clogging the pavement and flying in your face seagulls pooping on my head (seagulls take massive dumps, in case you didn’t know) cute birds that chirp too damn loud in the morning when I’m trying to sleep I also find birds scary.

38 Days Ago   I was born and raised in Rome, so Italian is my native language. Now I live in the US, and I’m basically bilingual. Yet, when I hear other people speak English with an accent, sometimes I have a hard time understanding what they’re saying.

40 Days Ago   Antarctica isn’t a huge, static block of ice where very little goes on. For the first time, scientists are getting a sense of just how active the continent’s extensive network of lakes, rivers, and streams is.

40 Days Ago   Scientists in Germany have 3D printed very intricate tiny objects using glass. And of course, one of these objects is a pretzel. In the future, the technique could be used to 3D print more useful things, like complex lenses, filters, and even ornaments that generally need highly skilled artisans to make.
