I bet you've never seen this statue before. Neither had I until today. It's "The African Renaissance Monument" in Dakar, Senegal.

The monument stands at a height of approximately 49 meters (160 feet), including its base, making it one of the tallest statues globally. It was designed by Senegalese architect Pierre Goudiaby Atepa and was built by a North Korean company. The statue was inaugurated on April 4, 2010, during Senegal's 50th independence anniversary celebration, and symbolizes Africa's emergence from a history of colonization and oppression and its progress toward a brighter future. ...

Which of these faces looks more trustworthy to you?

Science says that some people just get away with more stuff, because they have more trustworthy looking faces.

A trustworthy face, as psychologists have determined over years of research in this area, has two major characteristics: The eyebrows are slightly lifted, so that together, they form a kind of upside-down V shape; likewise, the corners of the mouth are also lifted slightly. An untrustworthy face, on the other hand, is the opposite: The eyebrows point slightly downward, forming a V shape, and the corners of the mouth are turned down a bit, too.

"Rather than having to photograph from behind wire fences, [I hope to] capture images of animals such as lions in the wild, free and unrestrained," writes Greg Van Dugteren of this image taken at New Zealand's Orana Wildlife Park.

Margaret Hamilton was the leader of the team that developed the flight software for the agency's Apollo missions. The concepts she and her team created became the building blocks for modern 'software engineering.' One example of the value of Hamilton's software work occurred during the Apollo 11 mission. Approximately three minutes before Eagle's touchdown on the moon, the software over rode a command to switch the flight computer's priority processing to a radar system whose 'on' switch had been manually activated due to a faulty written operations script provided to the crew. The action by the software permitted the mission to safely continue.

The green wings of luna moths, with their elegant, long tails, aren't just about style. New research finds they also help save the insects from becoming bat snacks by creating a distracting acoustic signal, which causes these predators to zero in on the wings rather than more vital body parts.

It's called a superhydrophobic knife and it slices water droplets easier than a butter-knife cuts through butter. As its name suggests, anything that is 'superhydrophobic' is highly hydrophobic, i.e., extremely difficult to wet. This special knife uses polyethylene - a common plastic - zinc, and copper. Its surfaces was dipped into a solution of silver nitrate and a superhydrophobic solution called HDFT for 20 seconds, and once it was washed and air-dried, it was super-great at repelling water.

In this amazing video, scientists have sucked the air out of the container and managed to find a pressure/temperature combination that's near the triple point of the fluid, which has been identified as cyclohexane - the triple point is the very precise temperature and pressure at which the three states of matter (solid, liquid and gas) exist in thermodynamic equilibrium.
