Scientists Discovers Corn Plants Make A Noise

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

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.

Japan’s 2011 Tsunami Sends Balls 8,000 Kilometres To Alaska

In March 2011, Japan was hit by the largest earthquake ever recorded.

It caused a tsunami–a huge wave that started out in the ocean. The tsunami swept onto the north-east coast of Japan and back into the sea, carrying away everything in its path.

Now, after travelling across the Pacific Ocean for more than a year, a soccer ball and a volleyball have washed up onto Middleton Island, off the coast of Alaska.

The man who found them plans to send them back to the two Japanese teenagers who lost them during the tsunami.

The balls were found two weeks apart and both balls had names on them. The soccer ball also had a school name and several messages.

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

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.

Does Ancient Antarctic Lake Hold Secrets To Life In Outer Space?

A team of Russian scientists in Antarctica has found an ancient lake buried under more than three kilometres of ice.

The lake – Lake Vostok – has been sealed off from the rest of the world for at least 15 million years.

Scientists think the lake may contain tiny organisms, like bacteria, which are not found anywhere else on earth.

If the organisms exist in the lake, it would be because they have been able to adapt to living in the darkness, saltiness and extreme cold of the hidden lake. In that case, they would likely have developed special features that no other organisms on earth have.

World’s Smallest Chameleon Discovered

Scientists have discovered a chameleon so small it could sit on your little finger.

The chameleon, which is about three centimetres long, lives on a small island called Nosy Hara, off the coast of Madagascar, in the Indian Ocean.

It is the smallest chameleon and possibly the smallest reptile ever discovered. It lives among rocks and leaves on the forest floor. At night it sleeps on plants, about five to 10 centimetres above the ground.

It is mostly grey and brown with an orange tail, and it doesn’t change colour like most chameleons do. The scientists say this is because it’s already the right colour to blend in with its surroundings.

12-Million-Year-Old Plant May Soon Be Extinct

Cycads, a very rare type of plant, are in danger of becoming extinct because of poachers.

Poaching usually means to hunt animals illegally. In this case, trees are being taken from the wild.

They are then secretly sold for a lot of money – up to $100,000 each – to people who collect unusual plants.

The first cycads existed during the time of the dinosaurs, during the Jurassic period. The kinds of cycads that are alive today have been around for 12 million years.

They look like a cross between a fern and a palm tree, and they can take hundreds of years to grow to their full size.

Europe In The Grip Of A Cold Snap

Some countries in Europe are experiencing a bitterly cold winter.

Ukraine, in eastern Europe, has been especially hard hit. More than 100 people have died there in the last week, as temperatures dropped as low as -30C. Many of the people who froze to death were homeless people living in the city’s capital, Kiev.

In Bosnia-Herzegovina, there have been avalanches and strong winds. The country declared a state of emergency.

One woman in Croatia had to have neighbours help her give birth to her baby after the ambulance could not reach her because of a blizzard. She later named her baby Snjezana, which is Snow White in Croatian.

TKN Exclusive: How Thailand’s Floods Have Affected Me

Nat Atherton is a Canadian living and working in Thailand. He gave TKN a first-hand account of the day-to-day havoc this year’s floods have caused.

The flooding here has been horrible. It hasn’t yet come into the centre of the capital (Bangkok), where I live, but has affected many of the people I work with.

Many of the poorer Thais live in the surrounding areas, which are flooded chest deep (1.5 metres) in some places.

I know a great many people who have lost their houses.

Many others haven’t been able to go home to check on their homes since rivers of dirty water separate their work from their houses.

Many well-known tourist districts have also been affected, including the world’s largest outdoor market, Chatuchak.
