Earthset from the Lunar Reconnaissance Orbiter : On the Moon, the Earth never rises or sets. If you were to sit on the surface of the Moon, you would see the Earth just hang in the sky. This is because the Moon always keeps the same side toward the Earth. Curiously, the featured image does picture the Earth setting over a lunar edge. This was possible because the image was taken from a spacecraft orbiting the Moon - specifically the Lunar Reconnaissance Orbiter . In fact, LRO orbits the Moon so fast that, from the spacecraft, the Earth appears to set anew about every two hours. The featured image captured one such Earthset about three months ago. By contrast, from the surface of the Earth, the Moon sets about once a day with the primary cause being the rotation of the Earth. LRO was launched in 2009 and, while creating a detailed three dimensional map of the Moons surface, is also surveying the Moon for water and possible good landing spots for future astronauts. via NASA

When Given Colored Construction Paper, Wasps Build Rainbow Colored Nests
I originally started making this material not necessarily for armors but more for cars and trains. [I wanted it] to squeeze like a sponge, but in a heavy duty kind of form of a sponge so we could put it in front of the car or a high speed train and take care of the impact. But when we saw the performance of the material, we started thinking about ballistics and bullets. And so I tested those and we saw that…the material can perform.
Afsaneh Rabiei. He developed a metal foam that is lightweight, strong, heat- and radiation-resistant, and, when incorporated in a bulletproof vest, for example, capable of shattering bullets on impact without injuring the person wearing it.

daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species from the great barrier reef using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye. (see more at bioquest studios)
coral growth rates in the great barrier reef have plummeted 40 percent in the last 40 years, a result, according to a recent study, of increased ocean acidification. since the beginning of the industrial revolution, about one third of the carbon dioxide that has been released into the atmosphere as a result of fossil fuels has been absorbed by the oceans, where it in turn prevents coral from using a mineral called aragonite to make their calcified skeletons.
new modelling has also shown that if ocean waters continue to warm by even one degree, which most now see as unstoppable, the coverage of corals on the great barrier reef could decline to less than 10 percent, which is a level too low for the reef to mount a recovery.
further complicating matters for the coral is the plastic detritus left by humans which now litter the oceans and which the coral now consume. unable to expel the plastic bits and thus take in nutrients, the coral slowly starve. a recent study found that each square kilometre of australia’s sea surface water is contaminated with approximately 4,000 pieces of tiny plastic.
This beautifully diverse group of sea slugs can be found in oceans worldwide, but its greatest variety is located in the magical habitat of warm, shallow reefs. It’s name comes from the Latin for “naked” (nudus), but it’s often informally called a “sea slug.” Today, a profile of a group of marine gastropods called Nudibranchia.
Unlike other mollusks (think snails), most nudibranchs have lost their shells, evolving other mechanisms for protection. For example, some are able to ingest and retain poisons found in prey, later secreting them for defense.
All known nudibranchs are carnivorous, feeding on a variety of sea life including sponges, other sea slugs, and barnacles. One species, Glaucus atlanticus, is known to prey on the Portuguese man o’ war!
Hermaphroditic, nudibranchs have a set of reproductive organs for both sexes, which means any creature can mate with another. That said, a nudibranch can’t fertilize itself.
According to National Geographic, “some nudibranchs are solar-powered, storing algae in their outer tissues and living off the sugars produced by the algae’s photosynthesis.”
The creature has very simple eyes (able to distinguish little more beyond light and dark), but have cephalic (head) tentacles that are sensitive to touch, taste, and smell. Its gills are uncovered, located behind their heart, and protrude in plumes on their back, making for a large surface area that grants more efficient oxygen exchange.

As you can see by these profiles, a universal constant amongst science ladies is a need for hairties.
What better way to celebrate Women’s History Month than by celebrating these amazing and accomplished women of science, brought to you by Lauren Goldberg (aka Auberg Designs on Etsy).
Each necklace sports the profile (or cameo) of a different woman who pioneered science in her own way. Available in silver, copper, or bronze with different finishes. So many phenomenal women, I can’t choose just one!
