The Indonesian Mimic Octopus, Thaumoctopus mimicus. This fascinating creature was discovered in 1998 off the coast of Sulawesi in Indonesia, the mimic octopus is the first known species to take on the characteristics of multiple species. This octopus is able to copy the physical likeness and movement of more than fifteen different species, including sea snakes, lionfish, flatfish, brittle stars, giant crabs, sea shells, stingrays, jellyfish, sea anemones, and mantis shrimp. This animal is so intelligent that it is able to discern which dangerous sea creature to impersonate that will present the greatest threat to its current possible predator. For example, scientists observed that when the octopus was attacked by territorial damselfishes, it mimicked the banded sea snake, a known predator of damselfishes.
This map shows 9323 earthquakes equal to or greater than 4.5 magnitude that occurred during 2011 on a global map in sequence from Jan. 1 through Dec. 31, with magnitude indicated by circle size and louder volume for higher magnitude quakes. (This is a pretty amazing presentation.) As you will see the greatest portion of…Read More
It was exactly one year ago today that Japan was struck by a disastrous earthquake and tsunami . . . and a nuclear meltdown followed. One year later, Bill Whitaker takes stock:
All along Japan’s northern coast it’s shocking to see the vast stretches of emptiness – a lifeless moonscape dotted with mountains of debris.
The only activity: Mechanical arms building heaps of debris higher and higher.
So much nothingness, one can’t help but wonder what’s been accomplished over the past year? … until you remember how this all began.
The magnitude 9.0 earthquake, the worst ever recorded in Japan, might end up a footnote compared to the black tide it triggered. The tsunami swept in off the Pacific and laid waste to everything in its path.
A coastline of cities and towns, factories and farms washed away in an instant.
Ebisu, the god of good fortune and the sea, was no match. Almost 20,000 people died or still are missing. So much death and destruction it took this country – an economic and technological giant – a whole year to achieve what today looks like . . . nothing.
“There is so much debris, but it exceeds the capacity of these communities to get rid of it, to incinerate it, to dump it. So it has to go somewhere else. And other communities around Japan have not been raising their hands,” said Jeff Kingston, who teaches Japanese history at Temple University Japan.
Some people collect stamps. Wolfram Research co-founder and author Theo Gray collects elements. Step into his office, and you’ll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and thousands of other chemical artifacts. But his real DIY masterpiece is the world’s first “periodic table table.” Within this masterfully constructed…Read More
Multiple-TED attendee and human factors expert, Ash Donaldson, wants us to better understand why we believe what we do. In this talk, Ash explains how our minds build belief and then breaks it down, showing us how and why humans are fooled into believing that things like Power Bands, anti-aging treatments and supplements actually work. Along the way, he tells us how as a trainee pilot he managed to nearly get himself killed by allowing his beliefs to rule logic and provable fact.
