Microplastics Threaten Marine Life In The Great Lakes

by

Tiny pieces of plastic – each about the size of a grain of sand – are posing a huge threat to marine life in the Great Lakes.

For the past two summers, researchers from an organization called 5 Gyres have been collecting water samples from the Great Lakes.

They used fine-mesh nets to skim the surface of the water.

When they looked at what they had collected, they found thousands of tiny plastic beads, each less than a millimetre.

At first the scientists didn’t know where these “microbeads” came from. Then they used an electron microscope to compare them to products such as face and body washes or toothpaste that people use to help scrub and polish our skin and teeth.

US Group Says Canadian Lobster Traps Are Endangering Whales

by

Canada has failed to protect the North Atlantic Right Whale by allowing the use of old-fashioned methods to catch lobsters and crabs, according to an environmental group in the United States.

Many Canadians who fish for lobsters and crabs use nets, traps and ropes that can tangle up whales and accidentally capture other sea creatures, they say.

The magazine on earth is published by The Natural Resources Defense Council in the US.

In a recent article they said Canada has no regulations to protect the endangered right whale from the old-fashioned fishing methods.

Canada Announces Protection For Endangered Birds

by

Environment Canada has issued an emergency protection order that will limit construction activity and loud industrial noise near the habitat of an endangered bird species.

The greater sage-grouse is a shy bird that lives in southeastern Alberta and Saskatchewan.

There are fewer than 150 adult birds left in Canada, and environmentalists believe the species could be extirpated (locally extinct) within five years unless it is protected.

The birds’ natural habitat is long prairie grass, but much of this grassland has been destroyed by agriculture and oil and gas development over the past hundred years.

In December 2013, Environment Canada – the government department responsible for the environment – issued an order that prohibits any activity that would disrupt the birds’ habitat during the spring mating season.

Student Doctor Finds Real, Life-Threatening Illness In “Patient-Actor”

by

A student doctor recently saved the life of an unusual patient, in a very unusual way.

Ryan Jones, a medical student at the University of Virginia School of Medicine, was practicing diagnosing illnesses.

As part of his training, he and other student doctors had to diagnose an actor who was playing the part of an ill patient.

The actor would act out symptoms of an illness he pretended to have, and the medical student had to figure out what the illness was.

Of course, the actors didn’t really have any illness—they were just pretending.

Except, in the case of Jim Malloy, he really did have the illness and didn’t know it.

Endangered Animals Making A Comeback In Canada

by

Seven Canadian species that were once considered endangered or nearly extinct are beginning to flourish again, thanks to efforts by conservationists.

Canadian Geographic magazine reported in its December 2013 issue that populations of endangered whooping cranes, North Pacific humpback whales, eastern wild turkeys, swift foxes, sea otters, wood bison and peregrine falcons have increased in recent years.

Most of them are no longer considered endangered.

Several factors contributed to the disappearance of these species, including loss of habitat, pesticides, disease and over-hunting.

The “Comet Of The Century” Set To Put On A Show

by

Comet ISON is about to put on a show.

Scientists around the world are watching as ISON streaks, ever-faster, towards the sun.

NASA has been studying ISON since December, when it was more than 800 million kilometres away.

Experts are calling Comet ISON as “the comet of the century.”

What is a comet? Here’s how astrophysicist Julie Abraham describes a comet: “It’s basically a big ball of dirty ice in orbit around the sun that gradually melts or burns up, spewing out debris and water in a plume blown out behind it.”

Scientists Find 60 New Species In Suriname Rainforest

by

Scientists have discovered 60 species of previously unknown plants and animals living in a remote rainforest in southeastern Suriname.

Suriname is a small country on the northeastern coast of South America, just north of Brazil.

It is located in a geographic area called the Guiana Shield, which contains more than one-quarter of the world’s rainforest.

An expedition of 16 field biologists spent three weeks in Suriname in 2012, exploring the remote, mountainous rainforest region.

Thirty indigenous men helped transport their food and equipment by boat and guided team through the forest.

MAVEN Spacecraft Takes Off For Mars

by

This week, a “robotic explorer” left Earth on its way to Mars.

It should get there next September. Mars is more than 700 million kilometres away.

The explorer is going to Mars to try to solve some of the planet’s mysteries.

For instance, why is Mars now a cold, dry planet when it started out warm and wet?

The Associated Press reports that “the early Martian atmosphere was thick enough to hold water and possibly support microbial life.”

Scientists at NASA want to know what happened to change that.

Olympic Torch Arrives Back From Outer Space

by

The Olympic torch has been to outer space and back.

The torch has even been on a spacewalk.

It’s the first time that has ever happened.

The torch will be used to light the flame that will launch the 2014 Sochi Winter Olympics, hosted by Russia.

On Nov. 7, a spacecraft called the Soyuz TMA-11M left Russia carrying three crew members and the Olympic torch.

It was bound for the International Space Station (ISS), which is in orbit around the Earth.

Two Russian cosmonauts on the ISS received the torch. Later, they brought it outside and symbolically handed it off to each other in open space. The hand-off took about an hour.

Philippines Hit By Massive Typhoon

by

There has been a terrible storm in the Philippines.

The Philippines is a country in southeast Asia.

Because it is an island in the Pacific Ocean, the Philippines often gets very bad weather, including earthquakes, volcanoes and typhoons.

However, Typhoon Haiyan is perhaps the worst natural disaster to ever befall the country.

The typhoon hit the Philippines last Friday.

Its winds of up to 300 kilometres an hour whipped up the ocean waves.

The storm also caused flooding and landslides.

The country’s National Red Cross has launched a huge program to help the people whose houses were destroyed by the typhoon.
