Scientists say the Arctic has undergone unusual, and increasingly rapid change over the past few decades as a result of climate change, including the appearance of the Pizzly bear — a grizzly-polar bear hybrid.

“There’s a lot of weird stuff going on in Alaska, and there’s a lot of weird stuff going on in Siberia, Scandinavia, Canada as well,” says environment and energy editor for Scientific American David Biello.

The modern phenomenon of air conditioning is something people in much of the developed world have become accustomed to. Now in China, India, Brazil and other developing countries people who have never had A/C are beginning to jump on the cool-air bandwagon.

The 19th and 20th century emergence of mechanized air has had a far-reaching impact on how modern architecture has developed. With global temperatures rising, scientists, architects and researchers are looking for new and more energy-efficient ways to keep people cool. 

The next time you eat out in a restaurant, consider the sounds around you. Is there music playing? Just the gentle hum of other people’s conversations? Maybe it’s relatively quiet.

Whatever the acoustic atmosphere, it could be affecting how you experience the flavor of the food and drink you’re consuming, according to a growing body of research.

In 1626, the French Jesuit Jean Leurechon (1591-1670) first coined the word “thermometer.” It appeared in his best-selling book, Récréation Mathématique, which he wrote under the nom de plume of Hendrik van Etten. (A subsequent English translation was entitled Mathematical Recreations, or a Collection of Sundry Excellent Problems Out of Ancient and Modern Philosophers Both Useful and Recreative).  

That electric green you see, juxtaposed with the water’s deep blue, makes for an eye-catching image. But in reality, it’s the “visual manifestation of an unhealthy ecosystem,” according to Timothy Davis, a molecular ecologist at the National Oceanic and Atmospheric Administration (NOAA).

This is no ordinary butterfly collection. It’s a showcase of blue morphos (Morpho didius), a species native to the forests of South America whose wings — especially the males’ — are famed for their brilliant aquamarine sheen. While the first two specimens are a typical male and female, the others are “gynandromorphs” — that is, specimens that contain both male and female cells.

In these butterflies, the trait manifests on the wings as a patchwork of colors and patterns, borrowed from both sexes.

Scientists, historians and archaeologists have long sought to figure out how, when, and from where the first humans arrived in the Americas. One group of geneticists believe they are another step closer to finding that answer. 

The first archaeological record of people in the Americas dates back to about 15,000 years ago. According to a new study published in Science, however, humans first stepped foot in the Americas much earlier — about 23,000 years ago. 

For most people, a road trip means sun, the sky, the sea, a mountain range. But if you've got a bit of geek in you, your sightseeing becomes even more enjoyable when you can learn something about the science history of your destination.

A five-year mission to bring wireless broadband internet service to Allegany County is moving forward. Portions of a new system should be operational by early fall, Legislator Dave Pullen told WBFO News.

The kilogram was defined back in 1795 in the context of water — “one liter of pure water at a temperature of four degrees Celsius and at standard atmospheric pressure.” A physical standard — a hunk of metal — was adopted a few years later.

Today, the kilogram standard is the only remaining measurement standard that is based on a physical artifact.

That means all the scales in the world are ultimately calibrated against a 125-year-old piece of metal kept in a vault on the outskirts of Paris. Its mass is the world’s definition of a kilogram.

Summer in the Sahara is scorching — sand temperatures can range between 149-158 degrees Fahrenheit. While skittering across the African desert at high noon might sound like a death wish, it’s only natural for the Saharan silver ant (Cataglyphis bombycina).

The insect emerges from its nest to forage midday and is capable of withstanding body temperatures up to about 127 degrees Fahrenheit. 

July is National Ice Cream Month. Last July, a Cincinnati woman made national headlines when she made a discovery that shocked her.

After sitting out for hours in the summer heat, an ice cream sandwich still appeared intact and just slightly melted. What gives? What natural (or unnatural) ingredient could make this frozen treat withstand 80 degree temperature?

This is Pluto — or, more specifically, a close-up of terrain bordering a heart-shaped feature dubbed “Tombaugh Regio,” for Pluto's discoverer, Clyde Tombaugh. The detail reveals a range of “young” mountains rising as high as 11,000 feet, which probably formed no more than 100 million years ago and might still be geologically active. 

NASA's New Horizons spacecraft captured the image about an hour and a half before making its closest approach to Pluto — a heralded arrival that occurred when many of us on the East Coast were eating breakfast this week.

The adult salamander pictured here has short limbs and toes, and gills sprouting from its head — features typical of amphibian larvae. But this species, known as the axolotl (pronounced ACK-suh-LAH-tuhl), is known for retaining these larva-like traits even after it reaches sexual maturity.

Everybody likes a good dinosaur story, but one of the best dinosaur stories of them all centers on the man who gave these remarkably extinct beasts their name.

Sir Richard Owen (1804-1892) was a celebrated naturalist and founder of the British Museum of Natural History. Some time around 1839, Owen began studying the bony remains of extinct races of reptiles: the carnivorous Megalosaurus, the herbivorous Iguanodon and the armored Hylaeosaurus.
