Volcano Eruption in Papua New Guinea - The shockwave is just amazing!

Darker Than Black
Surrey Nanosystems has developed a material darker than black which conducts heat seven and a half times better than copper, and has ten times the tensile strength of steel.

It’s called Vantablack, and it’s comprised of carbon nanotubes. Here’s a video.

Leatherback sea turtle hatchling. Leatherbacks are the largest turtles in the world, and are critically endangered.

I first learned about them when I was nine years old, and was a volunteer, alongside my mother, at the Marine Life Center. My cousin came on a “turtle walk” (when visitors can come alongside volunteers and watch sea turtles nest) and he fell into a hollow left behind, presumably, by a leatherback. These turtles are massive!

Parrotfish are responsible, in part, for the beautiful white, sandy beaches you stretch out on during summer break.

Their name is derived from their beak-like mouths which are used to scrape and pull off chunks of algae covered coral from reefs. Pharyngeal teeth (throat teeth!) help pulverize the chunks of coral. The coral is later eliminated… as sand. Here’s a parrotfish poop song to help explain.

Parrotfish are “a classification nightmare”. Many species can change gender, and their colors change depending upon their gender and phase. Some males keep harems, and when the dominant male dies a female from the group will change gender and then become the dominant male.

Some species of parrotfish create a mucous cocoon in which to sleep at night. Presumably to deter predators, as the membrane tastes and smells unpleasant.

Egg of an elephant bird (left - family Aepyornithidae) next to that of an ostrich (Struthio sp.). The elephant birds populated Madagascar and went extinct sometime in the 17th- or 18th century, most likely due to human impact. The egg in the Field’s collection is one of very few intact specimens in the world. One could make an omelette out of an egg this size that would feed about 120 people, which may have also contributed to that extinction.

The luna moth (Actias luna) is a member of the Saturniidae family. It sports pale green wings, and a wingspan up to 4.5 inches, which makes it one of the largest moths in North America.

Luna moths are just as famous for their adorable faces and antennae as they are for their stunning wings. The males have thicker antennae than the females, probably to help track down the ladies.

Adult luna moths have a very short lifespan. They live around seven days, and don’t have mouths or digestive systems. Their sole purpose is to mate, and females can lay up to several hundred eggs.

Peacecorn on imgur rescued a luna moth from an ant attack, and it left her a small number of eggs.

Peacecorn cared for them and documented their growth in pictures (some are in this post). See the story here.

I am following a grand total of nine blogs.

Appalling, isn’t it?

Bring me your favorite science blogs! I need reading material.

Allosaurus fed more like a falcon than a crocodile.
"Many people think of Allosaurus as a smaller and earlier version of T. rex, but our engineering analyses show that they were very different predators.”
Scientists combined current knowledge of how dinosaur relatives, like raptors and crocodilians, feed with information gleamed from dinosaur fossils to recreate the muscles of Allosaurus in computer models. They then ran simulations to see how Allosaurus may have fed on prey.

Fun Facts: This allosaurus and the stegosaurs are located at the Denver Museum of Nature and Science, where I used to take paleobiology night classes. The allosaurus was dug up by a teenage girl in the 90’s , and is the most photographed A. fragilis in history.

Meet the crabeater seal (Lobodon carcinophaga). It’s a charming specialized predator that lives on the coasts of Antarctica. It feeds almost exclusively on krill (90% of their diet) and sometimes cephalopods and antarctic fish.

Technique: The seal gobbles mouthfuls of krill and water drains through the spaces created by its teeth.

Crabeaters have little food competition, but as pups they are heavily preyed upon by leopard seals.

If you love the crabeater mug go here for a short story told by the person who photographed it.
