No Signs Of Life On Mars… Yet

by

Scientists have not found any signs of life on Mars yet, but they say a robotic vehicle called “Curiosity” is helping them learn a lot about the planet’s history and climate.

Curiosity landed on Mars in August 2012 after travelling through space for more than eight months.

It was sent to Mars by scientists from NASA in the United States.

Curiosity is a motorized vehicle called a “rover” which is controlled by scientists back on Earth.

It is about the size of a car and has six wheels that allow it to travel across the planet’s surface and climb over sand and rocks.

It also has a robotic arm, cameras, and instruments such as a scoop, drill and microscope that allow it to examine things it finds on the surface.

Then it transmits the information back to Earth.

The main purpose of Curiosity’s mission is to find out if anything could live on Mars, either now or in the past.

On Nov. 2, NASA scientists held a press conference to discuss what Curiosity had found in its first two months on Mars.

Earthquake Damage In Costa Rica Less Than Feared

by

Thank goodness for Costa Rica’s strict building codes.

They ensure that its buildings are extremely sturdy and well built. That helps account for the relatively small amount of damage the Central American country suffered after a powerful 7.6-magnitude earthquake last Wednesday.

The earthquake took place about 140 kms west of the country’s capital, San Jose.

In 1991, another 7.6-magnitude earthquake shook the country but it caused a lot of damage. This time, Costa Rica was saved by its new and updated building standards.

Endangered Right Whale Population is Growing

by

North Atlantic Right Whales are one of the most endangered whale species in the world.

But now their numbers are growing again, thanks to a plan to keep large ships away from the whales’ nursery and feeding grounds.

For many years the whales were hunted for their oil. Hunting was banned in 1937, but by the 1990s there were only a few hundred North Atlantic Right Whales left.

The whales live in the Atlantic Ocean, off the eastern coast of Canada and the United States. They spend the winters in warm southern waters, where most calves are born, then migrate north in the spring.

Many Right Whales spend each summer and fall in the Bay of Fundy, a large inlet of the Atlantic Ocean between the provinces of New Brunswick and Nova Scotia. The water there has large amounts of plankton – tiny organisms that are an important part of the whales’ diet.

Scientists Discovers Corn Plants Make A Noise

by

Most people know that plants react to light.

For instance, if a houseplant is near a window it will start to grow towards the light.

But what about sound?

New research shows that plants not only react to sound, but even produce sounds themselves.

Dr. Monica Gagliano is a researcher at The University of Western Australia. One day she was working in her herb garden and she started to wonder if plants were sensitive to sounds. Since she’s a scientist, she decided to find out.

She and some other researchers discovered something amazing. They found out that the roots of corn seedlings (very young corn plants) make clicking sounds.

Ontario, Quebec Experiencing Heat Wave

by

It’s hot outside. But just how hot? It’s “heat-wave” hot.

That’s according to Environment Canada, the official source for weather information in Canada, particularly for severe weather watches and warnings.

A heat wave is when the temperature outside reaches 32-degrees Celsius or higher for three or more days in a row.

Southern Ontario and Quebec are experiencing temperatures in the mid-30s. With the high humidity the provinces are also experiencing, the temperature outside feels more like 42 degrees.

World’s First Private Spacecraft Makes Successful Trip To International Space Station

by

Governments from just a handful of countries have flown into space.

But never has a private company successfully sent a spacecraft into space.

Not only is it extremely expensive, but it’s incredibly risky. There are a million things that can go wrong.

Last month an American company called Space Exploration Technologies – better known as SpaceX – made history by sending its unmanned Dragon spacecraft into space.

Millions Of Butterflies In Ontario And Eastern Canada

by

If you were sitting outside on April 16 in Eastern North America, you may have seen a wondrous site. That day, millions of Red Admiral butterflies flew in – or perhaps “blew in” – from the southern United States.

Drew Monkman is a local natualist (“nature watcher”) and writer, living in Peterborough, Ont. He tracks the habits of animals including butterflies.

He told TKN that the April 16 migration was “completely unprecedented. (The Red Admiral has) never been seen in these kinds of numbers.”

He said on that day there were probably several million butterflies, most of them Red Admiral, but there were other species as well.

Drew Monkman is a naturalist and butterfly expert living in Peterborough, Ont.
Why did this happen? This year in the southern United States like Texas, where the butterflies began their journey, the winter was “amazingly mild,” said Monkman. This allowed more butterflies to survive the winter and reproduce.

World’s Largest (And Stinkiest) Plant About To Bloom Near Niagara Falls

by

It’s stinky and it’s huge—and it’s about to bloom.

The world’s tallest flower is set to bloom this week.

Its scientific name is The Amorphophallus titanium (Titan Arum for short).

The extremely rare flower is at the Niagara Parks’ Floral Showhouse, near the Canadian Horseshoe Falls in Ontario. When it blooms, it will be the 22nd of its kind to bloom in a botanical garden.

Titan Arum is also known as the corpse flower. That’s because of the stinky odour it gives off. It smells like rotting meat.

Its horrible smell helps the flower attract insects that it needs for pollination. (Lots of insects are attracted to rotting meat.)

Titan arum normally grows in the rainforests of Sumatra.

However, this one—and another one that is also growing and will bloom after the first one—was donated by a man who lives in New Hampshire, U.S.

Raising Awareness About Prader-Willi Syndrome

by

Dante’s dad wants people to know about Prader-Willi Syndrome.

People with Prader-Willi Syndrome (PWS) feel hungry all the time. That’s hard for most of us to imagine. We’re used to eating a meal and then feeling full for about two hours.

But kids with Prader-Willi don’t feel full. After they’ve eaten, they want to eat again. But of course if they do that, they’ll eat too much—not just three meals a day. That can lead to obesity—being overweight—which can lead to health problems.

Dante, who is now seven-and-a-half, was born with PWS. His dad, Keegan Johnson, wants to make people aware of the condition in order to raise money for research and, eventually, a cure.
