How Cookiecutter Sharks Eat Is Terrifying

Do not be fooled by its adorable name—the cookiecutter shark attacks by suctioning its lips to the flesh of its victims, spins, and ejects a cylindrical plug of flesh from its prey!

An earthquake felt across South Asia

An earthquake felt across South Asia | HMHS History |

"The magnitude-7.8 earthquake that struck Nepal on Saturday morning destroyed parts of Kathmandu, trapped many people under rubble and killed more than 2,500 people. It was the worst to hit the country since a massive 1934 temblor killed more than 8,000."

Joshua Mason's curator insight, April 29, 2015 11:04 AM

It's absolutely devastating what happened to Nepal. Any loss of life is a tragedy but loss of this scale is unimaginable. It's going to be a difficult rebuilding process for the Nepalese whether that's coping with the loss or physically rebuilding the nation.


Watching footage of shakes, what struck me the most was hundreds of year old temples crumbling. Those just aren't something you can easily rebuild. The building can eventually be replaced but the significance of it is almost lost. 


Those temples, like the homes in the area, were most likely not built up to a standard that could withstand earthquakes or at least earthquakes of this magnitude. It's easy to see how destruction on this scale can occur in large urban populations that were not designed to stand against such a dramatic event.

Kristin Mandsager San Bento's curator insight, May 1, 2015 3:59 PM

I've experienced earthquakes more times than I've ever felt the need.  We used to get them all the time it seemed in Japan.  My bed would role across the room.  It got to the point where I just slept through them.  If I had even felt a shake half as violent as what Nepal went through I could not even imagine the fright.  I wonder how long the India and Eurasia tectonic plates will stay on top of each other?  Or if a few more earth quakes will split the area?

How the warming Arctic might be behind Boston's deep freeze

How the warming Arctic might be behind Boston's deep freeze | HMHS History |
There may be a counterintuitive explanation for the deep freeze that hit New England this winter: The rapidly warming Arctic is causing big disruptions in the jet stream, which carries weather across North America. Is this the worst winter you've experienced?

Perhaps this article will sway some climate change skeptics...

Paul Farias's curator insight, April 9, 2015 11:33 AM

So bizarre how the rate of the arctic warming causes us to get smacked with the cold weather. Its one of those things that are like how does the jet stream actually work. Including the fact that California is getting hit with a major drought.

The 'Underwater Waterfall' Illusion at Mauritius Island

The 'Underwater Waterfall' Illusion at Mauritius Island | HMHS History |

"When viewed from above, a runoff of sand and silt creates the impression of an ‘underwater waterfall’, just off the coast of the island nation of Mauritius in the Indian Ocean."

this look pretty nice i would like to go see it in person

Victoria McNamara's curator insight, December 12, 2013 1:36 PM

By looking at this picture you automatically think its a waterfall within the water. This image is actually just showing the mix of sand and silt deposits mixing together. The light to dark colors is what makes it look like a waterfall. 

Jess Deady's curator insight, May 4, 2014 9:24 PM

Another spectacular sight. Of course, you will need a plane or helicopter to venture above it to see it, but this illusion is pretty nifty.

Popocatépetl | HMHS History |

Via Seth Dixon
Brett Sinica's curator insight, September 29, 2013 1:11 PM

Among active volcanos in the world, this would be an extremly devastating one if it were to explode.  Less than 50 miles from Mexico City, which is home to more than 20 million people in its entirety could be of threat.  Just this year in July, there was steam and ash released which cancelled flights in and out of Mexico City and Toluca.  That's a mere fraction of what could happen if this volcano had a full-blown explosion.  On a lighter note, on days with good weather, this volcano is quite a spectacle of nearby cities and is the second highest peak in Mexico.

Giselle Figueroa's curator insight, October 31, 2014 11:39 PM

This is a active volcano, the last eruption was on 2013 (a year ago), It is the second highest volcano in Mexico. Popocatépetl means "montaña que humea" (wet mountain). I love everything that have to be with nature, Volcano are a very interesting creation of nature. 

Edgar Manasseh Jr.'s curator insight, February 11, 2015 11:01 PM

Amazing volcano located in pueblo Mexico, located in the eastern half of Mexico and is one of the most active volcanoes in Mexico. its been around for awhile and just recently in 94 got active its a very important part of Mexico and is very interesting to look at from your own perspective.

This infographic is a fascinating way to put into context the very recent trend of rising global temperatures.  This is worth scrolling all the way through to make the ending all the more meaningful.  Oh yeah, and August 2016 was the hottest month in recorded history...only 11 months of record-breaking temperatures.

Earth is Home to 3.02 Trillion Trees

Earth is Home to 3.02 Trillion Trees | HMHS History |

"A new census that shows that Earth is host to a staggering 3.02 trillion trees — more than scientists expected.The most recent estimate only counted 400 billion trees, reports Rachel Ehrenberg. Because prior studies used satellite technology alone instead of including data from on-the-ground tree density studies, writes Ehrenberg, they missed the mark. They also estimate that since human civilization began, 45.8 percent of all trees been lost."

This thing is sick! I would love to make one of these i would play with this thing for hours and I'm an adult. And they say video games are useless, the kinect can be used for things other than dance offs and such.

Angels Landing

Angel's Landing in Utah's Zion National Park (map) is one of my favorite hikes with an amazing view.The geomorphology of 'red rock' country is stunning and it's sheer cliffs are bound to captivate the imagination.  If you want something like this but with a more European flavor, watch National Geographic's Andrew Evans climb Preikestolen in Norway.

This post was interesting to me because living in Virginia Beach, we dont see much interesting amounts of snow, nor rainfall, so we dont know about the many things weather can do. Now knowing this about weather makes it more intersting,and makes me wonder what else could happen??
Cam E's curator insight, January 29, 2014 2:20 PM

The mystery of the world is personally one of my favorite topics, as we've not even come close to exploring every inch of our own planet. As much as I want to see us expand outwards, we should not avoid looking to our own planet with an explorer's eye like many did in the past. This particular article makes me wonder how many unexplained events that ended up in folk legend were the cause of some unique weather pattern or then-unexplained event which we better understand today. I personally saw something like this very recently. On a trip up north towards Vermont for some skiing I spotted that the moon was particularly large that one night. Later on as we were passing by Boston we saw what appeared to be a black line cutting straight through the moon. It extended to each end of the horizon and while it was a cloud, no others were in the sky, and it was so uniform throughout that it made me doubt my own common sense!

Astrobleme | HMHS History |

"Lake Manicouagan lies in an astrobleme in central Quebec covering an area of approximately 1206 square miles—an area half the size of Delaware. An astrobleme is a scar left on the Earth’s surface from an impact of a meteorite. Lake Manicouagan is the result of one of the largest identified asteroid or comet impacts on Earth. In the middle of the lake, on Rene-Levasseur Island, Mount Babel rises 3,123 feet into the air.


Lake Manicouagan is thought to have formed about 212 million years ago plus or minus 4 million years.  This happened when an approximately 3.1 mile-diameter asteroid crashed into Earth toward the end of the Triassic period. Some scientists speculate that this impact may have been responsible for the mass extinction that wiped out more than half of all living species."

Via Seth Dixon
Al Picozzi's curator insight, September 18, 2013 8:33 PM

This amazing picture shows how vulnerable the earth is to space born hazards.  This 3.1 mile-diameter asteroid might have caused 1/2 the living species on the earth at that time, 212 million years or so ago, to become extinct.  Man has the abilty to adapt to changes to the environment, unlike the dinosaurs.  The question is though do we have the ability to adapt to an event of this magnitude?  Hopefully we will not have to test out this question.
