What’s the big deal? Well, the findings show that the thermal […]
I’ve seen a lot of strange Chinese ideas, but this one is definitely something else – the Chinese government is bent on building an 8,000+ mile railroad (sounds plausible) connecting China, Russia, Canada, and the U.S. that includes a 125 mile undersea tunnel spanning the Bering Strait. A report in China’s state-run Beijing Times claims the nation […]
“Juanita Knits the Planet” is a short comic strip that tells the story of Juanita, a very creative little girl. In fact, she’s only 10 microns tall, small enough for the entire comic strip to fit on a strand of human hair, making it the smallest comic in the world. The strip was printed for the […]
Some 65 million years ago an asteroid impact caused countless species of land, marine and plant life to become extinct, including the mighty dinosaur which dominated the planet for millions of years. Not all species of the dinosaur group vanished, however. You’ve guess right: birds! Now, a new study sheds light on why birds were […]
Self driving cars are hitting the road in Sweden! Volvo Car Group’s “Drive Me” project involving 100 cars is now being tested in the streets in the Swedish city of Gothenburg.
