Algae invasion! Sea Ghosts create beautiful light show on China’s beach

China's Xiangbi'ao beach shone with a majestic sparkling glow-in-the-dark blue hue last week after a natural phenomenon called "Sea Ghosts" invaded the waters.  Sea Ghost or "Sea Sparkle" is created by the growth of an algal bloom called Noctiluca scintallans, a type of single-cell animal that loves to munch on plankton.  The organisms multiply when nitrogen and phosphorus from farm fertilizer run-off enters the water.  Beautiful, yes - but harmful to the ecosystem.  When the blooms die, they sink to the bottom of the sea where they decompose, consuming huge amounts of oxygen and killing other marine life. Check out the Sea Sparkle on China's Xiangbi'ao beach in the pictorial gallery below.

Check out the “dirty thunderstorm” raging inside the mouth of erupting Mount Sakurajima

Mount Sakurajima, a 3,665-foot high volcano in Japan, erupted this week sending a plume of smoke more than 3 miles into the air. Even better, all the flying ash and rock created a static electricity storm inside the mouth of the volcano. A photographer captured a picture of the storm which raged within the Showa crater on the southeastern side of the volcano. Storms such as this are called “dirty thunderstorms”. They are rare in general but fairly common at Mount Sakurajima. So far Mount Sakurajima has seen 50 eruptions this year.

Computer programming is a foundational skill that lets future generations do things with information we can hardly dream of

Fun Ways To Get Kids Interested In Learning How To Code We live in a world filled with information. This has always been true but today, the tools exist for all of us to see and use that information. Coding and computer programming are the foundational skills that will let future generations do things with the information around us that we can hardly dream of. We now must start teaching those skills to our children. Fringe Benefits At their roots, programming and coding are about two things: working with information and solving problems. It does not take much thought to realize that these two concepts are applicable in a virtually endless array of different applications. Children who learn the fundamentals of coding will be able…

Meet the new Atlas robot and see how well it reacts to bullying

Boston Dynamics continues to blow us away with its amazingly lifelike robots and such is the case with the newest version of the Atlas robot. Atlas is a humanoid robot made by Boston Dynamics (the makers of the ever-popular BigDog military robot). Atlas can walk on two legs and use its “arms” to lift, carry, and climb (and maybe one day, fight back against robot bullies).  Atlas is even sophisticated enough to adjust and navigate through tight, cluttered places. Atlas features 28 hydraulically-actuated degrees of freedom and a sensor head with cameras and a laser range finer (LIDAR). It stands 5 feet 9 inches and weighs 180 pounds (compared to its 330-pound predecessor, that’s lightweight). There are several Atlas robots being manufactured. Check out the…

Amazing gravitational waves discovery – what they are and why they’re so important

In 1916, Albert Einstein predicted that any event that disturbs spacetime will produce ripples that spread throughout the entire Universe. He called these ripples gravitational waves. This week, one hundred years after Einstein’s prediction, scientists revealed they had finally detected gravitational waves. The discovery being called the greatest scientific advance this century.  Here’s how they did it and why the discovery is such a big deal. What’s all this mumbo-jumbo about gravitational waves and spacetime? In scientific geek-speak, gravitational waves are disturbances in the fabric of spacetime. If you drag your finger through a bowl of water, you will notice waves follow the path of your finger and ripple outward towards the edge of the bowl. Einstein predicted that the same thing happens when a heavy object…

Get the thought that all tiny particles in our universe are shaped like little round balls out of your head!

Scientists have worked for a very long time trying to figure out a theory called quantum field theory. Quantum field theory is a body of laws that describe how the tiny little particles all around us interact – particles tinier than atoms, protons, electrons, and neutrons. We’re talking super tiny particles with names like baryons, quarks, muons, and likely many more that we don’t know about yet. Whatever the particle, we tend to think of these objects as little dots, spheres, or tiny circles. Even the models in books illustrate these particles as tiny little balls. Turns out that scientists thought of them that way too – and when they looked at these in a different perspective, suddenly their work in quantum field theory became…

The Mars Curiosity rover happily whiling away its time working in the sand

This past week, NASA's Curiosity rover spent quite a bit of its time happily playing in the sand – on Mars.  In December 2016, Curiosity reached a new frontier on Mars – the Bagnold Dunes.  The dunes are located on the northwestern flank of Mount Sharp (officially given the rather geeky name, Aeolis Mons), a mountain at the center of the Gale Crater, and feature a landscape unlike anything Curiosity has come across before.  In fact, in some photos, the sandy dunes and mountainous Mars terrain in the background look quite earthly.   Here is Curiosity earlier in the year.  You can see the dunes in the distance as Curiosity makes it way toward them.   The dune to the left of Curiosity is Namib…

China’s Yuto rover sends back remarkable hi-def, full color pictures from Moon

China's Chang'e 3 lander and its little companion rover, Yutu, have sent back a set of truly remarkable pictures of the Moon's surface – all in full color and hi-def resolution!  These are the first photos taken from the surface of the moon in nearly 40 years. On December 23, 2013, the Chang'e 3 lander sent back this four-segment mosaic of Yutu (which means "Jade Rabbit" in Chinese) as it set off to study the Moon.   Chang'e 3 landed in a lava-filled crater, Mare Imbrium, the largest basin on the moon's near side.  In 2014, Chang'e 3 sent back this mosiac showing Yutu's seemingly willy-nilly tracks as it trekked across the surface of moon.   Here's what the rocks on the moon look like up…

This is what Niagara Falls looks like when all the water is shut off

Would you believe the millions of gallons of water that rush over Niagara Falls can be turned off? It’s happened before and is about to happen again. All the water from the American side of Niagara Falls (the American Falls) will be rerouted in order to allow repairs to infrastructure. When that happens, we’ll see the bone-dry cliff where the water previously roared. The last time the falls were shutoff was 1969 (see photo above and pictorial gallery below). The Army Corps of Engineers stopped the flow in order to see how the rushing water was eroding the falls. To do this, the 60,000 gallon-per second flow was diverted to Horseshoe Falls and the Robert Moses generating plant upriver. Now the parks department once again wants to…

Did you know China has a telescope on the Moon?

Did you know China has a telescope on the Moon? The 15-centimeter telescope was delivered to the moon aboard the Chang’e 3 lunar lander which landed on the moon in December 2013.  In the photo above, the small arrow points to the Chang'e 3 rover and the big arrow points to the Chang'e 3 lander and telescope base. If you’ve looked through a telescope before, you know that because of the earth’s rotation, the stars do not stay fixed in the viewfinder for very long. Since the moon rotates 27 times more slowly than Earth, the scope is much easier to stay fixed on stars.  The scope sees in ultraviolet light too, a big advantage for any telescope outside of the earth’s atmosphere. The telescope is remote…
