A cunning Dolphin in Institute for Marine Mammal Studies

A cunning Dolphin in Institute for Marine Mammal Studies

At the Institute for Marine Mammal Studies in Mississippi, Kelly the dolphin has built up quite a reputation. All the dolphins at the institute are trained to hold onto any litter that falls into their pools until they see a trainer when they can trade the litter for fish. In this way, the dolphins help to keep their pools clean.

Kelly has taken this task one step further. When people drop paper into the water she hides it under a rock at the bottom of the pool. The next time a trainer passes, she goes down to the rock and tears off a piece of paper to give to the trainer. After a fish reward, she goes back down, tears off another piece of paper get another fish, and so on. This behaviour is interesting because it shows that Kelly has a sense of the future and delays gratification. She has realised that a big piece of paper gets the same reward as a small piece and so delivers only small pieces to keep the extra food coming. She has, in effect, trained the humans.

Her cunning has not stopped there. One day, when a gull flew into her pool, she grabbed it, waited for the trainers and then gave it to them. It was a large bird and so the trainers gave her lots of fish. This seemed to give Kelly a new idea. The next time she was fed, instead of eating the last fish, she took it to the bottom of the pool and hid it under the rock where she had been hiding the paper. When no trainers were present, she brought the fish to the surface and used it to lure the gulls, which she would catch to get even more fish. After mastering this lucrative strategy, she taught her calf, who taught other calves, and so gull-baiting has become a hot game among the dolphins.


In Singapore Water Is Made Of Pee? By Newater

SINGAPORE — They call it "NEWater" but it's just the opposite: recycled sewage water packed in clear plastic bottles, ready for drinking.

Surrounded by oceans but lacking adequate clean water resources, Singapore hopes to get 55% of its drinking water from recycled sewer water by 2060.

The level might seem ludicrous if so many other countries weren't confronting their own water shortages.

But it's still not enough to make up for the lack of rain, so water districts are also considering new sources— say, the Pacific Ocean — that for years was considered too expensive. Recycled water is another option that's coming to the fore as affordable and environmentally friendly.

"In many countries, you call it sewage, but that sound so … messy," said George Madhavan, ‪director of corporate development with Singapore's Public Utilities Board.‬‬

"Basically, you drink the water, you go to the toilet, you pee and we collect it back and clean it," he said.

Today NEWater makes up 30% of Singapore's water, almost all of it used for industrial purposes. But bottles are also given away at civic events to get people used to the idea of drinking what once would have been poured into the ocean. Singapore isn't the only place looking for new ways to get potable water.

Process Of Newater 

The recycling process produces water that's extremely pure and extremely clean, using technology has existed for years. Effluent is first sent through a microfiltration system, then through reverse osmosis and finally sterilized under UV light.

That's simply a version of what happens naturally, water experts say. Ocean water evaporates to become rain and falls into lakes and rivers or ends up deep underground. Eventually, it finds its way back in the sea and the entire process begins again.

"The water you drink today is the same water the dinosaurs drank. Water recycling just speeds up the process," Dorsey said.

Countries like Singapore foster innovation because they have to, providing lessons that the United States can learn from, experts say.

Newater requires less energy than desalinization and is cheaper than pumping water long distances. There's also less wastewater discharge into rivers and oceans, which helps control water pollution, she said.


So far, just as in Singapore, U.S. water districts either use recycled water for industrial or agricultural purposes or add it to water heading toward water treatment plants.

While it might seem to make more sense to just drink the recycled water, two things get in the way. The first is public perception.

"We need to overcome that 'yuck' factor and embrace the natural systems that have worked for thousands of years," Finn said.

"Water is naturally filtered as it goes through the earth and we've all been drinking it for a long time and we're all fine," he said. Getting the public to embrace recycled water will require "reinforcing that fact and tying it to nature."

There's also a practical reason to send the recycled water through water treatment plants— that's where water distribution systems begin. "If you wanted to pipe recycled water direct to customers you'd have to redo the system," Dorsey said.

A Two-Ocean Lake

Almost all Rivers and lakes flow in one direction and goes into a Oceans.

Did you ever heard of a lake that runs in two different directions ?

There is a lake in yellowstone national park in America that flows in two different directions and flows towards two different oceans.

Even though it's a small lake, but its has unique features on its own. One and only lake in world which flows into two different oceans. It is also known as two ocean lake.

All the water in the lake comes from the melting of ice on the mountains. when the water level increases the lakes unique feature can be seen.

Wondering how lake water is going to Oceans?

The east side of the lake drains by way of the Lewis River to the Pacific Ocean and the west side of the lake drains by way of the Firehole River to the Atlantic Ocean.

 ISA Lake was first discovered in 1891 by Hiram M. Chittenden during the development of yellowstone national park.
