Many people believe video games are intellectually lazy and have a poor effect on students. There are, however, a growing number of teachers, students, and parents who are using one video game in particular as an educational tool.

Minecraft is a video game that has gained an enormous following. According to, more than 20 million people have purchased a version of the game.

Zack Klein, CEO of and co-founder of Vimeo described Minecraft in terms of another popular childhood toy — Lego.

Picture of the Week: Blue Morpho Butterflies

Aug 6, 2015

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, animals 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.

Why screams are scary

Aug 5, 2015

Leave it to a group of new parents to be inspired to study the effects of screaming on the human brain.

David Poeppel, a professor of psychology and neuroscience at New York University and director of the Max Planck Institute's Department of Neuroscience in Frankfurt, Germany, normally studies speech and communication. Recently, however, he found himself sharing a laboratory with a group of new parents in New York.

Doctors and health experts have long warned that a diet high in saturated fats can lead to multiple health issues including heart problems and increased risk of type 2 diabetes. A new study examining the eating habits of dolphins, however, seems to indicate that certain saturated fats may in fact reduce the risk of diabetes. 

Are you ready for the ultimate geek road trip? 12 suggestions.

Aug 4, 2015

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. 

Picture of the Week: Kelvin-Helmholtz Clouds

Jul 29, 2015

Maybe you’ve seen tsunami-shaped clouds like these, rolling through Earth’s atmosphere. These repeating curls result from a flow of air hitting a layer of stagnant or slower-moving air below it. The turbulence is known as Kelvin-Helmholtz instability, named after its discoverers, William Thomson—better known as Lord Kelvin—and Hermann von Helmholtz.

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?

Climate change is imperiling bumblebees in the US and Europe

Jul 27, 2015

A recent report in the journal Science says climate change has caused bumblebee habitat to shrink by as much as 180 miles in the last 40 years — a pace researchers say is quite alarming.

Jeremy Kerr, the lead author on the study and a professor of biology at the University of Ottawa, says the bumblebee is caught in a kind of vice: its habitat is not extending northward to adjust to changing temperatures and the habitat in its southern range is diminishing.

Looks Fishy, Tastes Fishy. But Where's the Fish?

Jul 23, 2015

Eleven years ago, chef James Corwell had a revelation in Japan. He was teaching cooking to the U.S. Navy stationed there, and one morning, he woke up before dawn to make a pilgrimage to Tokyo’s Tsukiji fish market, the largest in the world. Under the roof of an open-air warehouse, he walked the aisles and perused row after row of hulking frozen tuna, steam rising from their carcasses. Corwell, one of the only certified master chefs in the United States, was astounded.

Track a Plant's Movement

Jul 21, 2015

Though you may not realize it, every day the plants around you are moving…all by themselves. Even though most plants have roots that bind them to the surface they grow on, plants are able to stretch, grow, and bend to adjust to changes in their environment.

Right after Pearl Harbor, the US government began construction of a weapons factory on a site just outside of Denver, Colorado. Years later, the plant was converted into a pesticide factory. Now, the site is one of the nation's largest wildlife refuges — and, in part, it's thanks to that majestic American symbol, the bald eagle.

Is marijuana really an effective drug? Surprisingly, scientists have no solid answer

Jul 19, 2015

One would think that with medical marijuana now legal in 23 states, the science to support its efficacy would be fairly definitive. Surprisingly, that's not the case.

Despite the fierce political tussles and competing medical claims the truth is this: Very little solid scientific evidence exists to either confirm or dispute marijuana’s effectiveness as a drug or its potential for harm.

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.

Pluto probe makes closest approach this week

For nine years, scientists have waited for this week to arrive. New Horizons, the piano-sized space probe launched back in January 2006, makes its closest approach to the distant world Pluto on Tuesday.

Microbes may hold the key to future high-tech meds and materials

Jul 11, 2015

When most people think about advanced technology, they imagine robots or hypersonic vehicles or new additions to the Internet of Things. But there is another tool that may have more high-tech potential than anything else: biology.

“Biology can do things that no other man-made technology or chemistry can do,” says Alicia Jackson, deputy director of the Biological Technologies Office at the Defense Advanced Research Projects Agency (DARPA).

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. 

The crystal ball on a hilltop outside Boston doesn’t look into the future, but provides an invaluable connection to the past. This antique technology, called a Campbell-Stokes sunshine recorder, helps researchers maintain North America’s longest-running weather record.

A group of researchers have discovered the existence of previously unknown lymphatic vessels in the brain — a stunning find that upends current medical science and could have far-reaching implications for the study and treatment of neurological diseases like Alzheimers and multiple sclerosis.
