Archaeologists might not get into the field to go digging through ancient toilets. But, that’s just what a team from the University of Copenhagen did, and with good reason, too. What goes into human mouths must come out, and the leavings can offer a glimpse into ancient lifestyles. Especially interesting, as it turns out, are findings that aren’t even human. The parasites that live and reproduce in our bodies say a lot more a ...read more
Acne, bronchitis, pink eye, ear infections, and sexually transmitted diseases are just a few of the illnesses treatable by antibiotics — assuming that the bacteria that cause these illnesses are not resistant to antibiotics.
Antibiotic resistance, one of the most urgent threats to public health, occurs when antibiotics are unable to kill the bacteria causing an infection. According to the Centers for Disease Control, each year in the United States at least 2 million people become infected ...read more
The Rhea Fire in Oklahoma, seen in this image, grew to megafire size. And it wasn’t the only blaze to scorch the High Plains in April.

That’s right — this image of the roaring Rhea Fire in Oklahoma was captured not from an aircraft but by a satellite about 500 miles above Earth’s surface.

I love geology. It’s what I do. It asks questions fundamental to our understanding of the planet (and beyond), questions that I feel should resonate with everyone on the planet because we live on Earth! Every day, each of us interacts with geologic processes whether we realize it or not – maybe it is the topography we travel across to get to work, maybe it is the materials we use in our daily lives, maybe it is ...read more

The Surfrider Foundation is pleased to release its 2017 Clean Water Annual Report, which tracks the progress of our Blue Water Task Force (BWTF) and Ocean Friendly Gardens (OFG) programs during the calendar year of 2017. At a time when it can be difficult to depend on the federal agencies tasked with protecting our clean water and healthy coasts, it is encouraging to see how much a dedicated network of volunteers can accomplish in jus ...read more
But looks are deceiving: the West has seen too little of the white stuff

Views of Earth like this once seemed almost profound — at least I always thought so. That’s because we weren’t accustomed to seeing ...read more

If you’ve ever tried to keep up with a child on the playground, only to collapse in a panting heap, take heart. You might as well be trying to compete with a triathlete.
Researchers from France and Australia conducted a physiological test comparing 8- to 12-year-old boys with both untrained adult men and endurance athletes. The children, despite having no special training, were more comparable to the runners and triathlon competitors, the scientists say. ...read more
The planet Uranus. It smells bad here. (Credit: NASA)
Scientists confirm that Uranus’ atmosphere contains hydrogen sulfide, a compound long suspected to be swirling about in the planet’s clouds.
Using the Gemini North telescope in Hawaii, researchers from the United Kingdom analyzed Uranus using a technique known as spectroscopy to identify the elements contained within. They relied on the Near-Infrared Integral Field Spectrometer (NIFS) at Gemini for the task, which invo ...read more
