Solar panels, paired with batteries to enable power at night, can produce several orders of magnitude more electricity than is consumed by the entirety of human civilization … Even if the solar industry were only to generate 40% of the world’s electricity with photovoltaics by 2040, that would mean installing more than 400 GW of solar capacity per year for the next 25 years. We absolutely believe that solar power can and will become the world’s predominant source of energy within our lifetimes, but there are obviously a lot of panels that have to be manufactured and installed in order for that to happen.
Map of the World by Natural Skin Color
i’m really dumbfounded that i never realized skin colour is literally just caused by being closer to or farther from the equator and the resulting sun exposure and skin darkening
actually, its an adaptation. natural selection. people with darker skin are selected for in areas near the equator, where the melanin that causes the darker color protects them from radiation and protects them from skin cancer and other health defects, and because they are healthier they can pass on that trait more. people near the poles have lighter skin because it allows them absorb more of the limited sunlight to convert to vitamin d.
THIS IS THE THING SOME PEOPLE HATE OTHER PEOPLE OVER.
Evolution of melanin levels based on geographical location.
Mapped And this is why hating over skin colour is stupid.
Future tense Not quite as far forward as the BBC one I posted last week.
Model-Slash-Coder Shatters a Dozen Tired Stereotypes
If you have preconceived notions about models being dumb and coders being nerdy white dudes, prepare to abandon them. Lyndsey Scott has modeled for brands like DKNY, Victoria’s Secret, Gucci and Prada. But she also knows Python, Objective C, and iOS, and builds apps in her spare time.
In a profile by Carmel Diamicis on Pando Daily, Scott explains that she graduated from Amherst College in 2006 with a dual-degree in computer science — and 3 years later, found herself modeling for Calvin Klein, as “the first ever African American to get an exclusive contract with the company for New York Fashion Week.”
But up until recently, while modeling, her tech background was kept secret. She tells Diamicis:
The industry makes an effort to reduce the model and, in a way, simplify things. The way they marketed me a lot of times was as younger than I am. They wouldn’t talk about my education, they wouldn’t talk about me … In a way I understand. Youth is valued more than a college education.
One of Scott’s apps — available in the Apple store — is called iPort, and it’s basically a digital portfolio for models. (She tells Business Insider she started coding in middle school!) As seen in this tongue-in-cheek video, Scott is not just smart and beautiful — she’s also got a sense of humor. She also wrote a moving Quora post about going from physically unattractive to physically attractive:
The swan Lyndsey Scott’s testimony on Quora makes for good reading.
Scientists examine a 15-year-old girl who lived in the Inca Empire, then was sacrificed and remained frozen for 500 years …
Unearthed in 1999 from the 22,000-foot summit of Mount Llullaillaco, a volcano 300 miles west of here near the Chilean border, their frozen bodies were among the best preserved mummies ever found, with internal organs intact, blood still present in the heart and lungs, and skin and facial features mostly unscathed. No special effort had been made to preserve them. The cold and the dry, thin air did all the work. They froze to death as they slept, and 500 years later still looked like sleeping children, not mummies.
Half a millennium later Incredible—who needs ‘forces beyond all comprehension’ to preserve a body for 500 years?
A Hole in Mars
Credit: NASA, JPL, U. Arizona
Back in 2007, black spots were discovered on Mars that are so dark that nothing inside can be seen. Quite possibly, the spots are entrances to deep underground caves capable of protecting Martian life, were it to exist.
The unusual hole pictured above was found on the slopes of the giant Martian volcano Arsia Mons. The above image was captured three weeks ago by the HiRISE instrument onboard the Mars Reconnaissance Orbiter currently circling Mars.
The holes were originally identified on lower resolution images from the Mars Odyssey spacecraft, The above hole is about the size of a football field and is so deep that it is completely unilluminated by the Sun. Such holes and underground caves might be prime targets for future spacecraft, robots, and even the next generation of human interplanetary explorers.
Life on Mars The other kind.
