Dolphins name themselves | Science News for Kids

Dolphins name themselves | Science News for Kids: "To call a dolphin, just whistle a squeaky shout-out.

Bottlenose dolphins answer to high-pitched bursts of sound. But each animal responds to only one specific trill. That trill is called its “signature whistle,” explain Stephanie King and Vincent Janik of the University of St. Andrews in Scotland. Their new finding appeared June 22 in the Proceedings of the National Academy of Sciences.
Each dolphin develops a signature whistle — a distinct tune — for itself. Dolphins broadcast their tunes to others. The tunes seem to act as a sort of audible nametag."

Animals under Antarctic ice? | Science News for Kids

Animals under Antarctic ice? | Science News for Kids: "Lake Vostok is the seventh-largest lake on Earth. It is also the fourth deepest. Although it was discovered more than 20 years ago, humans have never laid eyes on it. And that’s because it lies beneath 3.7 kilometers (2.3 miles) of ice in the center of Antarctica. But its remote site has not kept scientists from trying to probe this lake and whatever it may hide. And if one team is correct, the mysterious lake has indeed been hiding a shocking mix of living things. Perhaps thousands of different organisms."

Maths and Stats by Email | Money: "Article The value of money  
   

It’s clear that a one dollar coin is worth two 50 cent coins. Yet here in Australia, 50 cent coins are bigger, heavier, and made of similar metals. So why is the dollar coin worth more?

The short answer is that government tells us. In Australia, there are many laws about our money. One important law in this country states that Australian money must be accepted as a method of payment. These laws make sure that a one dollar coin is worth one dollar. But this isn’t the only way that money can be valued."

Video: How Rap Battles Are Helping High Schoolers Learn to Love Science | Underwire | Wired.com: "
Back in 2002, the immeasurably talented MC of Blackalicious known as Gift of Gab wrote a lyrically athletic track called “Chemical Calisthenics.” For those who could follow his rapid-fire style, it was an immensely great science lesson and one of the best raps about chemistry ever. But he’s got nothing on Jabari Johnson, a high school senior from Harlem who can rhyme about kinetic energy better than most people can talk about it.

“Here’s the lesson, I know it kinda hurts but if you truly want to work then there must be progressions cause, FD=W the rule, and the unit measurement for the product is called joules, cool,” Johnson raps on “Quest for Joulelry,” which outlines the physics equation of Force times Distance equals Work."

Bernie Krause: The voice of the natural world | Video on TED.com

Bernie Krause: The voice of the natural world | Video on TED.com: "Bernie Krause has been recording wild soundscapes -- the wind in the trees, the chirping of birds, the subtle sounds of insect larvae -- for 45 years. In that time, he has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe. A surprising look at what we can learn through nature's symphonies, from the grunting of a sea anemone to the sad calls of a beaver in mourning.

Bernie Krause's legendary soundscapes uncover nature’s rich sonic tapestry -- along with some unexpected results. "

Two young scientists break down plastics with bacteria | Video on TED.com

Two young scientists break down plastics with bacteria | Video on TED.com: "Once it's created, plastic (almost) never dies. While in 12th grade Miranda Wang and Jeanny Yao went in search of a new bacteria to biodegrade plastic -- specifically by breaking down phthalates, a harmful plasticizer. They found an answer surprisingly close to home.

Miranda Wang and Jeanny Yao have identified a new bacteria that breaks down nasty compounds called phthalates, common to flexible plastics and linked to health problems. And they’re still teenagers."

Home, plastic home | Science News for Kids

Home, plastic home | Science News for Kids: "We live in an increasingly plastic world. Much of this plastic does not easily degrade and so survives to pollute the environment. But a great deal of trashed plastic will break into tinier bits that eventually wash into the ocean. There this debris has begun creating new homes for microbes, research now shows.

Plastic trash in the ocean hosts a diverse world of one-celled organisms, observe Erik Zettler, Tracy Mincer and Linda Amaral-Zettler. The three work at the Woods Hole Oceanographic Institution and Marine Biological Laboratory, both in Woods Hole, Mass. They have given a new name to microbes and their plastic homes: the plastisphere (PLAS ti sfeer)."

Saltwater crocodiles | EOL: Learning and Education Group

Saltwater crocodiles | EOL: Learning and Education Group: "The city of Darwin in Australia’s Northern Territory lies in the heart of crocodile country. In the 1950s, saltwater crocodiles were shot, skinned, and turned into shoes and handbags. After hunting was banned in the 1970s, crocodile numbers climbed. Now there’s a croc for every man, woman, and child in Darwin. Can the human citizens learn to live alongside their toothy neighbors?"
