Sankid Pre-school, Kohuwala celebrations

It was a jubilant day of red for the energetic little youngsters of Sankid Pre-school, Kohuwala. They celebrated a 'Day of Red' recently. Dressed smartly in white T-shirts, the children painted, played and made handiwork to their heart's content.

A theme that was prevalent throughout the event was the liberal use of recycled bottles. The most popular was the making of a juicy little apple tree. Eshani Abeywickrama, the headmistress of Sankid Pre-school and the staff said the event focused primarily on teaching students about the importance of recycling, thereby grooming a future generation that is concerned about the welfare of their environment from a young age.

Alaskan butterfly's natural anti-freeze

The US State of Alaska is famous for its extreme seasonal changes - with high temperatures in summer and freezing cold in winter, meaning that only the toughest animals can survive.

The Oeneis Tanana is a rare cross between two other species of arctic butterfly, and it has inherited some of their best features for coping with extreme conditions.

One of its ways to cope with the cold is to produce a substance that stops its blood from freezing in winter while it hibernates, a bit like the antifreeze liquid that's used to stop car windscreens getting icy.

Scientists think that the Oeneis Tanana may be the only species of butterfly that's unique to Alaska and can't be found anywhere else in the world.

Butterflies are particularly quick to react to climate change, so scientists hope that monitoring the Oeneis Tanana could help them to understand changes to the Arctic environment.

New Zealand ‘cat burglar’ stole stealing underwear

A real life 'cat burglar' has been stealing socks and men's underwear in New Zealand.

In two months, Brigit the cat brought home 11 pairs of underpants and more than 50 socks from her night-time raids.

Brigit's owner, Sarah Nathan realised her cat's strange obsession and posted on Facebook to find the victims and give them back their belongings.

She told the BBC that the trouble first began when she found odd bits of underwear that didn't belong to anyone in the house.

Then one day she saw Brigit walk into the lounge 'carrying a sock like a kitten' and realised what was going on.

“Now it's getting silly” she wrote on Facebook, “Every morning we wake up to more ... Someone must be missing this stuff.”

Megalodons – Rulers of the Sea

A Megalodon is a big shark. It has rough skin and a curved body. Megalodons are extinct now but they lived 66-56 million years ago. They ruled the sea until the earth's sea levels fell.

Megalodons feasted on fish, turtles and mammals like whales. A Megalodon's tooth is as big as an adult hand. Did you know that a Megalodon is bigger than a bus!

New smartphone app developed

A new smartphone app has been developed that can detect a number of medical conditions by looking at your wee. The app is called the Uchek and has been shown off in Los Angeles, United States.

The app tests 25 health issues such as diabetes, infections and liver problems. To use the app people dip a special strip of card into their wee and watch it change colour. They then take a photograph of the strip with their smartphone and the app says if there’s a problem.

The app was invented by Myshkin Ingawale. The app is expected to cost around £13 which includes five test sticks. The developers hope it will improve healthcare in developing countries.
