In the crisp Andes air, a drone flew at an altitude of about 16,000 feet (4,900 meters) in order to map and track the glaciers in Peru. This marks the highest altitude a drone has flown for mapping purposes in current scientific literature, according to a paper released in November in The Cryosphere.
Using a drone to map glaciers is way easier than manually staking out individual data points and provides much crisper images than satellites. “The ultimate goal was to be down in ...read more
Damage caused by a 2011 earthquake in Oklahoma, likely caused by waste-water injection by humans. USGS.
Earthquakes are common across much of North America. The most famous might be the area along the San Andreas fault in California, where the Pacific and North American plates are sliding side-by-side, generating earthquakes in the process. Even the interior of North America has some major earthquake zones, like the New Madrid Seismic Zone that runs along the Mississippi River from Illinois to ...read more

It’s tough being an adult giant tortoise in the Galapagos Islands—they’re always one step away from flipping upside down. Whether it’s from a fight for male dominance or treading over a jagged field of lava rocks, being unable to get back up is among the most common ways these giant tortoises can die.

A seascape of fear? New study suggests fear of sharks shapes ecosystems. Photo Credit: Narchuk/Shutterstock
It’s kind of incredible how our fears can shape our behaviors. When Jaws was released in 1975, it fundamentally changed how we interact with sharks. In the years that followed, we hunted these large marine predators more intensely, and came to view them as terrible monsters—attitudes scientists still fight to this day. But while our fears are largely unfounded, there are ...read more

When you’re choosing a drink at a bar, what goes into that decision? We know that taste has a lot to do with it, but according to this study, emotions may come into play as well: more specifically, the emotions brought about by the type of alcohol itself. Here, researchers used an online survey of almost 30,000 people around the world to explore the emotions associated with drinking different kids of alcohol. They found that “Overall 29.8% of respondents r ...read more

Virtual reality experiences can provide an uncanny sense of immersion that tricks participants’ brains into believing they are walking on that narrow beam high above a city or are being chased by a monster through dark halls. The New Reality Company wants to push the boundaries of virtual reality by adding real-world props and additional sensory stimuli b ...read more

Compared to hunting and gathering, farming can seem like pretty easy work. But the skeletons of Central European women who lived during agriculture’s earliest days would like to tell you otherwise.
An analysis of prehistoric women’s upper arm bones shows they took on formidable tasks of manual labor, likely during the course of tilling, harvesting and otherwise managing ...read more

Science, especially these days, can move slowly. The days of big leaps in our understanding are mostly behind us, and the progress of scientists is typically slow, but steady. That’s why something like quantum computers, which you’ve probably heard a lot about, have been so slow to actually arrive.
