Mummies With Hair Gel

The Ancient Egyptians probably used hair gel to style their hair, new research on mummies shows.

Scientists at the University of Manchester, UK published an article in the Journal of Archaeological Science that said, “…in cases where the (mummies’) hair was styled, the embalming process was adapted to preserve the hairstyle.”

In other words, when the bodies were turned into mummies, the embalmers made sure their hair didn’t get mussed.

The researchers studied hair from 18 mummies who lived around 300 B.C. in Egypt.

Under a microscope, the scientists noticed that the hair on nine of the mummies had a coating on it. When they analysed it, it turned out to be made of plant and animal fats.

Politics

Young People Can Get Involved In Upcoming Election

Ontario, like four other Canadian provinces, will hold a provincial election this fall.

Members of Provincial Parliament (MPPs) and the Premier of the province will be chosen.

Depending on the province and district, other positions will also be elected.

In one of Ontario’s districts, Scarborough-Agincourt, Soo Wong is running for MPP.

TKN asked her what young people can do to feel part of the political process when they’re not yet old enough to vote.

“It is the responsibility of every Canadian to understand what elections are about,” she said. “All of the young people will sooner or later become adults. It’s not just about today, but about moving this province forward.”

She said that young people need to be knowledgeable about the candidates and the issues so that when it is their time to vote, they are prepared.

Space Junk Re-Enters Earth’s Atmosphere

A bus-sized chunk of space trash fell out of the sky on Friday or Saturday, and NASA isn’t quite sure where it landed.

They say it likely landed in the Pacific Ocean off the west coast of the United States. They are fairly certain that it didn’t cause any injuries.

The space junk was made up of fragments of a 6.3 tonne satellite that is no longer in use.

The Upper Atmosphere Research Satellite (UARS) was sent into space in 1991 and hasn’t been used since 2005. Its job was to collect information about chemicals in the atmosphere.

As many as 26 pieces of the satellite weighing up to 135 kilograms likely survived re-entry into Earth’s atmosphere. Most fragments burned up before reaching earth.

Blue Jays New Logo “Leaked” Online

The Blue Jays baseball team is changing its logo.

Teams often change their logo when they want to portray their team in a new way.

In this case, the Jays likely want their logo to emphasize the fact that they are Canadian.

Their new logo design is a big secret. They don’t want anyone to know what it will look like until they unveil it to the media and the public at a big event.

The logo they posted on their site looks quite a bit like an old logo they used to have, with the Canadian maple leaf quite a bit bigger.

However, the website Uni Watch (Uni stands for uniform) has obtained what it says is a copy of the proposed logo.

Physical Activity Can Boost Kids’ Brains

Most people agree that doing schoolwork, puzzles, math and reading help kids get smarter. But did you know that a good workout can also help you learn more easily?

Scientists say that physical exercise gets more blood flowing through a person’s brain, and helps them think better.

It also causes the brain to release a protein (called brain-derived neurotrophic factor) which makes new brain cells grow.

Researchers say kids who are active and fit perform better on memory tests. It affects certain areas of the brain, like the hippocampus and the basal ganglia.

Children who aren’t as active are more likely to become easily distracted.

Rare Albino Hummingbird Seen In Colorado

A rare albino hummingbird may have been spotted in Colorado.

Albino hummingbirds have a genetic condition that prevents their body from producing a natural chemical called “melanin.” Melanin is a chemical that gives most birds their beautiful colours.

Because Albino hummingbirds aren’t coloured, their feathers are white. They have pink bill and whitish or pink legs and feet. They may either have red or pink eyes.

The pink or red colour is caused by the red of their blood vessels.

Artist Only Draws In His Sleep

Lee Hadwin is a talented artist. He has drawn sketches of horses, celebrities, and beautiful landscapes. He only draws in black and white. Oh, and there is one other thing. Hadwin only draws in his sleep.

Ever since he was about four years old, he has been waking up to discover detailed drawings beside his bed.

But he doesn’t remember ever having done the drawings.

When he is awake, Hadwin says he can’t draw at all. In fact, he has no interest in art. During the day, he works as a nurse.

When he was young, Hadwin, who now lives in London, England, used to cover his walls and tables with his sketches.

In his teens, the drawings became more detailed and intricate.

LEGO Figures In Space

In August, a rocket was sent to deliver a space probe, called Juno, to Jupiter to study the planet.

The probe carried three unique stowaways.

Three special LEGO figures, made of aluminum, are accompanying Juno on its five-year mission. The figures look like the Roman god Jupiter, his sister Juno and the Italian astronomer Galileo.

Jupiter carries a lightning bolt. Juno has a magnifying glass to help her search for truth. And Galileo carries a telescope and a model of the planet Jupiter.

People at NASA approached LEGO and asked them to design the special minifigs, which cost about $5,000 each. They had to build them very carefully so they didn’t interfere with any of the probe’s sensitive instruments.

NFL Football Season Begins… Phew!

The National Football League (NFL) just completed its first week of the season.

It was an eventful week that saw all 32 teams play. But the season almost didn’t happen.

Over the summer the players and the owners argued over many different issues including the safety of the players, the number of games each team plays, and the players’ salaries.

Many experts believed that the season would be “lost.” They thought that football, like hockey in 2004, would simply be cancelled.

The owners and players discussed their concerns throughout the summer and, on July 25, they finally announced they had come to an agreement about these important issues.

It’s DejaVu For Apple All Over Again

Last year, someone who worked at Apple, the company that makes computers and cell phones, made a big mistake.

They lost a top-secret prototype.

A prototype is a one-of-a-kind model they build of a new phone they’re thinking of manufacturing. It’s kept secret so no other company will find out what they’re doing and try to copy them.

The person who had the prototype accidentally left it in a bar. A journalist found it and put pictures of it on the Internet. It was a big scandal.

Well, it has apparently happened again.

Apple developed a prototype for the iPhone 5 they will be releasing soon. And once again, an employee has accidentally left it in a bar, according to technology website CNET.
