This tiny camera takes 3D images of your innards
|
view preview
This tiny camera invented by scientists F. Levent Degertekin can provide high-definition 3D images of your arteries. The camera, which is the size of an uncooked quinoa grain, uses ultrasound imaging techniques to capture what going on inside the body. The images produced can be used in the surgical theatre, giving doctors a direct view of obstructions in a blood vessel.

On Venus it snows metal
|
view preview
At the very top of Venus’s mountains, below a thick layer of clouds, is snow. But not snow as we know it - with some surfaces reaching 480°C, Venus is way too hot for that. So what is this stuff? Researchers have figured out that Venus's heat is vaporising minerals called galena and bismuthinite, causing them to enter the atmosphere as a metallic mist before condensing into a shiny, metallic frost that rains down on the mountaintops.

Shock-absorbing goo found within bones
|
view preview
A viscous fluid made out of citrate and water is what gives our bones flexibility. The gooey fluid is trapped between the tiny crystals of calcium phosphate that form our bones, absorbing shocks and allowing movement. Without this fluid the crystals fuse together and become less flexible and brittle.

Tiny octopus hatchling
|
view preview
This tiny octopus hatchling looks like it wants to pick a fight with the eraser! This is a baby Caribbean pygmy octopus that was born at the Mote Marine Laboratory Aquarium in Florida in March. As you can see, it was extremely tiny at only a day old when this image was taken, but even when fully grown it will only be the size of a dollar coin.

Blood orange!
|
view preview
The blood orange is a variety of orange (Citrus × sinensis) with crimson, almost-blood-colored flesh. The fruit is smaller than an average orange; its skin is usually pitted, but can be smooth. The distinctive dark flesh color is due to the presence of anthocyanins, a family of antioxidant pigments common to many flowers and fruit, but uncommon in citrus fruits. The flesh develops its characteristic maroon color when the fruit develops with low temperatures during the night.

A moth that looks and smells like bird poop
|
view preview
This odd species is Macrocilix maia, a moth found all over Asia, including India, Japan, Korea, China and Borneo. Its wing patterning features two symmetrical patterns that look like flies or caterpillars feeding on a bird dropping, which could act as a deterrent for predators. The moth even smells like bird droppings.

Vancouver Island marmots are one of the world's rarest animals
|
view preview
Thanks to deforestation, road building, and other human activity, these sweet little guys have become so rare that in 1997, just 102 Vancouver Island marmots remained in the wild. But conservation efforts have brought them back from the brink, with around 300 captive-bred individuals released into the wild in 2010, and 26 wild litters born last year, producing 80 pups. Researchers state that climate change may further reduce or impact subalpine habitats along with associated forage plants.

Indeed, our paradox
|
view preview
We have taller buildings but shorter tempers; wider freeways but narrower viewpoints; we spend more but have less; we buy more but enjoy it less; we have bigger houses and smaller families; more conveniences, yet less time; we have more degrees but less sense; more knowledge but less judgement; more experts, yet more problems; we have more gadgets but less satisfaction; more medicine, yet less wellness; we take more vitamins but see fewer results. We drink too much; smoke too much; spend too recklessly; laugh too little; drive too fast; get too angry quickly; stay up too late; get up too tired; read too seldom; watch TV too much and pray too seldom. We have multiplied our possessions, but reduced our values; we fly in faster planes to arriv ...
