This bird might look like a holiday ornament, but it is actually a rare half-female, half-male northern cardinal, with female plumage on the left and male on the right. A new study suggests being half-and-half carries consequences: The cardinal didn’t have a mate, and observers never heard it sing.

There’s an innovative new light technology that's trying to change the way people think about "artificial light." In Italian company called CoeLux has developed a new light source that recreates the look of sunlight through a skylight so well that it can trick both human brains and cameras.

It’s a high tech LED skylight that’s designed to provide "sunlight" for interior spaces cut off from the outdoors. One of the main ideas behind it is that to create realistic sunlight, you can’t just simulate the sun… you need to recreate the atmosphere as well.

The scientists who invented the light figured out how to use a thin coating of nanoparticles to accurately simulate sunlight through Earth’s atmosphere and the effect known as Rayleigh scattering ...

Sumatran rhinoceroses are believed to be the oldest surviving rhino species - and the closest surviving relative of woolly rhinos, which died off 10 000 years ago. Apart from being the smallest rhino, they're completely covered in hair (shown above), especially the young ones. Their hair is very soft and they also sound like humpback whales when you hear them, making them incredibly cute.

Richard P. Feynman (1918 - 1988) was a New York City born, Nobel Prize winner in Physics in 1965. He was an American theoretical physicist known for his work in quantum mechanics, as well as in particle physics for which he proposed the parton model.

Feynman developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams (below).


His passion for science and education later lead him to develop a universal learning model, now called the Feynman Technique, that could help you learn practically anything no matter how difficult or complicated. As long you or the educator uses simple terminology (no complicated words or terms), you ...

This is the semi-transparent eyelid of the red-eyed tree frog, Agalychnis Callidryas. Frogs aren't the only creatures with 'third eyelids' that keep their eyes moist without blocking vision completely. Sharks, cats, crocodiles, polar bears and camels have them too.

You're looking at the world’s oldest woven linen garment called the Tarkhan Dress. At 5100 to 5500 years old, it dates to the dawn of the kingdom of Egypt. After it was found in the early 1900s, archeologists have concluded that it signals the complexity and wealth of the ancient society that produced it. The rips at the bottom of the garment also suggests that it probably fell past the knees originally.

A handful of garments of similar age have survived to the present day, but those were simply wrapped or draped around the body. The Tarkhan dress, on the other hand, is ancient haute couture. With its tailored sleeves, V-neck, and narrow pleats, it would look perfectly at home in a modern department store. ...

Nicknamed ‘goldenbugs’, this pretty little molten gold beetle is the golden tortoise beetle (Charidotella sexpunctata). It grows to around 5.0 to 7.0 mm in length and favour foods such as sweet potato and morning glory. Strangely, it can completely change colour while having sex.

This lady beetle (Coccinellidae) is protecting its enemy. The cocoon between its legs holds a parasitoid wasp larva (Dinocampus coccinellae), which fed on the beetle’s insides before bursting from its belly. Researchers have discovered what makes the beetles act as babysitters: They are infected with a brain-controlling virus. When the larva emerges and spins its cocoon, the virus makes the beetle freeze in place, protecting the baby wasp from predators. ...
