This is so perfect, for the time you look at this image, you don’t know if it’s a boy and girl, a girl and a girl, a boy and a boy, a black man and a white girl, a white man and an asian girl, you know nothing. Just the simplicity of the connection and the beauty of two human beings sharing love and that is all that should ever matter.
Actually, Due to the slight prognathism of the maxilla, the smaller more rounded cranial vault. The sharper and less defined lower mandible, and less protruding supraobital ridges, the conclusion can be reached that the individual on the left is female, and of African American decent. However the individual on the right shows a larger more oblong cranium, heaver more protruding supraobital ridges, a flatter maxilla with less prognathism. Also the lower mandible of this individual is heaver, more defined and square. From the presence of these features the conclusion can be reached that the individual on the right is male of Caucasian decent. Also due to the advanced (but not complete) obliteration of the cranial sutures, and the presence of a third molar in each individuals, it can also be said that both of these individuals are between the ages of 25 and 40.
Google’s Machine Learning Algorithms Outpacing Engineers’ Ability to Understand How they Work
“Google no longer understands how its “deep learning” decision-making computer systems have made themselves so good at recognizing things in photos.
What stunned [Google Software Engineer] Quoc V. Le is that the software has learned to pick out features in things like paper shredders that people can’t easily spot – you’ve seen one shredder, you’ve seen them all, practically. But not so for Google’s monster.
Many of Quoc’s pals had trouble identifying paper shredders when he showed them pictures of the machines, he said. The computer system has a greater success rate, and he isn’t quite sure how he could write a program to do this.
Google researchers can no longer explain exactly how the system has learned to spot certain objects, because the programming appears to think independently from its creators, and its complex cognitive processes are inscrutable. "
The microscope images above show that DRACO -“Double-stranded RNA (dsRNA) Activated Caspase Oligomerizer”- successfully treats viral infections. In the left set of four photos, rhinovirus (the common cold virus) kills untreated human cells (lower left), whereas DRACO has no toxicity in uninfected cells (upper right) and cures an infected cell population (lower right). Similarly, in the right set of four photos, dengue hemorrhagic fever virus kills untreated monkey cells (lower left), whereas DRACO has no toxicity in uninfected cells (upper right) and cures an infected cell population (lower right).
(I urgently need a flask full of DRACO right now)
We are all scientists.
Beautiful hi-res black & white photos of vintage NASA facilities from the 1920s through the 1960s. The first one, from 1949, is an Analog Computing Machine, an early version of the modern computer. Many more here. (via Brain Pickings)

“The most obvious thing to say about the telescope is that it’s enormous. Even when you’re standing right next to it, or on it, the size of the telescope is hard to comprehend.”
Puerto Rico’s Aricebo Observatory celebrates its 50th anniversary of listening to the skies this year. It’s the largest radio telescope in the world, built into a natural sinkhole in the tropics, providing a prime view of our own solar system and those beyond, as well as some breathtaking views of the island itself.
Nadia Drake has a wonderful tribute to Aricebo at Wired, full of crazy history, stunning photos, and some quality time with her dad (who is kind of a big deal). Give it a read.
In the era of exoplanets, and as we zero in on good spots to listen in on for possible signs of intelligence, it’s important to remember how crucial places like Aricebo were, and continue to be to astronomy. If we can build that, imagine what else we can do!

We may not know everything about the universe. We might not even know a sliver of nothing about the universe, but that knowledge (tiny though it may be), that need that we have to press forward, to discover, to know…it is one of our best assets. It keeps us moving forward.

Creating solutions for space, creates solutions on Earth.
Many of NASA’s solutions for space exploration have been adapted for use on Earth. These adapted technologies are known as NASA spinoffs. To date there have been over 1,800 NASA spinoffs. The Apollo program led to many spinoffs, including CAT scans, better water purification technology, a life raft that can withstand choppy conditions at sea, and athletics shoes that were adapted from moon boot technology. Memory foam was even originally developed by NASA to improve the safety of aircraft cushions. Recently a new technology startup Scanadu developed the first real life Star Trek tricorder, which uses the same technology as the Mars Curiosity rover.
NASA has continued to better lives on Earth by developing innovative technologies for the space shuttle and Viking spacecraft that were adapted to create more functional artificial limbs for amputees and insulin pumps for diabetics. NASA also developed fire resistant polymer fabric, which protects firefighters and military personnel. One of the latest NASA spinoffs, the FINDER radar, helps emergency responders rescue victims of disasters. NASA technology has protected us and we should protect its budget.
NASA is valuable both for space exploration and for bettering life on Earth. The government shutdown is halting innovation. Write to Congress to tell them you want the government shutdown to end and for NASA to continue innovation for space and Earth.
