clipper's remarks: They were studying the way exposure to chlorine vapor can cause Asthma. It was believed that out door pools allowed Chlorine to evaporate more quickly. This was more an assumption than a fact. Chlorine Gas and HCl or Hydrogen Chloride, which becomes Hydrochloric Acid, when it dissolves in water as a matter of course, is best in the stomach for digestion, or with or with the Alkali NaOH (Sodium hydroxide) which becomes the neutral Salt
It Does Not Belong in the Lungs.
Why do we use chemical Pan Microbicides, when there is the potential to give water its own version of an immune system?
Creeks, rivers and Oceans Don't need Chlorine to remain clean. Why should we think we have a better defense using Chlorine.
killing all microbes can turn water Sterile and Stagnant. We need Oxygenated Water,(Waterfall) and microbes can be part of a self contained Eco=system
Pools don't need Chlorine, they need things like Fish . this will also help recycle biological 'waste' we produce naturally

Swimming in outdoor chlorinated pools appears to increase the odds of developing childhood asthma, say Belgian researchers.

Previous studies have identified the link between chlorine and asthma, but the new findings published in the European Respiratory Journal cast doubt on the idea that outdoor pools are safer than indoor ones because chlorine vapours don't remain trapped inside an enclosed space.

"What is new in this study is that we looked at outdoor pools for the first time," says Professor Alfred Bernard, a toxicologist at Catholic University of Louvain

Asthma, which affects more than 300 million people worldwide, is the most common paediatric chronic illness. Symptoms include wheezing, shortness of breath, coughing and chest tightness

children tend to spend more time in outdoor pools

As a result children are more likely to swallow chlorinated water or ingest vapours, which contain chemicals that attack the cellular barriers protecting the lung from allergens, says Bernard

Chemists in the UK have developed a way to convert methane gas into a solid that looks like granulated sugar - making it easier to store.

Professor Andrew Cooper and his colleagues at the University of Liverpool have found that they can trap methane in a material made of silica and water, called 'dry water'.

They report their findings in Nature News.

Methane is seen as a viable alternative fuel, with experts estimating that deposits worldwide could contain more energy than coal, oil and all other fossil fuels combined.

There is a huge amount of energy in these resources

The question is how much of that material can we recover

Most of that methane is locked inside ice crystals in the Arctic or at the bottom of the ocean, where the pressure is high, the temperature is low, or both, which makes extracting those deposits difficult.

A chunk of white methane hydrate from the ocean depths is ice cold in your hand, but hold a lit match to it and yellow and blue flames rise from the methane

Eighty million years without sex

Asexual organisms are usually short-lived

The mystery of how an animal has survived for 80 million years without sex has been solved by UK scientists.

A Cambridge team says the creature owes its existence to a genetic quirk that offers some recompense for its prolonged celibacy.

Many asexual organisms have died out because they cannot adapt to changes in the natural world.

But an evolutionary trick allows this pond-dweller to survive when conditions change, researchers report in Science.

There could be some benefit to millions of years without sex after all

Dr Alan Tunnacliffe, University of Cambridge

The animal is a tiny invertebrate known as a bdelloid rotifer. It lives in freshwater pools. If deprived of water, it survives in a desiccated state until water becomes available again.

The secret to this novel survival mechanism lies in a twist of asexual reproduction, whereby the animal is able to make two separate proteins from two different copies of a key gene.

Nemo's nose helps find way home

clipper's remarks: They discovered some of the scents that attracted the clown fish to to the reefs that provide a suitable habitat. The scent from the leaves of one coastal plant Xanthostemon, a kind of myrtle attracted them. They also found scents, such as the leaves from the Melaleuca Nervosa, a kind of paperbark which is another type of myrtle, that repelled them. They say this could have implications regarding tree planting and reforestation near marine habitats.

The animated clownfish Nemo may have found his way home a lot sooner if he had trusted his nose

research by scientists from Australia, France and the US, has revealed that a species of clownfish (Amphiprion percula) uses its olfactory senses to help it locate a suitable habitat.

The findings appear in the latest edition of the Proceedings of the Royal Society B.

Professor Geoff Jones of James Cook University, Townsville, says that although previous research has shown clownfish can smell, these new findings identify the scents they are using.

"We've actually narrowed down the chemical signals that they may be using to find their home."

Almost all exhibited a strong preference for water collected from reefs that contained islands.

The researchers then used water that contained the scent of an anemone or leaves from coastal plants such as Xanthostemon.

When given a choice between scented or unscented water the fish spent more than 90% of their time in the scented water.

Researchers have split water into hydrogen and oxygen by replicating how plants use photosynthesis to make carbohydrates.

The team of Australian and US researchers says their findings, published in the latest Angewandte Chemie International Edition could lead to a cheap and easy way of making hydrogen, which many experts believe is the green fuel of the future.

Professor Leone Spiccia, of Monash University's School of Chemistry says the team has mimicked the process of photosynthesis, whereby plants convert light and atmospheric carbon dioxide into energy.

The new system involves an electrode coated with a proton conductor that is then impregnated with a form of manganese.

Manganese clusters are essential to a plant's ability to use water, carbon dioxide and sunlight to make carbohydrates

However instead of creating carbohydrates, the team have used nature's recipe to split water into its two elements, oxygen and hydrogen.

Scientists have created two new types of materials that can bend light the wrong way, creating the first step toward an invisibility cloaking device.

the vanishing act takes place on a nanoscale, measured in billionths of a metre

experiments, led by Professor Xiang Zhang at the University of California at Berkeley and the Lawrence Berkeley National Laboratory, are reported simultaneously today in the British journal Nature and the US-based journal Science.

Both are so-called metamaterials, artificially engineered structures that have properties not seen in nature, such as negative refractive index

When you see a fish in the water, the fish will appear to be in front of the position it really is. Or if you put a stick in the water, the stick seems to bend away from you

The negative refraction achieved by the teams at Berkeley would be different

Instead of the fish appearing to be slightly ahead of where it is in the water, it would actually appear to be above the water's surface

Even Jules Verne did not foresee this one. Deep down at the very bottom of the Atlantic Ocean, geochemist Andrea Koschinsky has found something truly extraordinary: "It's water," she says, "but not as we know it."

At over 3 kilometres beneath the surface, sitting atop what could be a huge bubble of magma, it's the hottest water ever found on Earth. The fluid is in a "supercritical" state that has never before been seen in nature.

What Makes Earth Special Compared to Other Planets

Earth is one special planet.

It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays. But many scientists agree our planet's most special feature might just be us.

"It's the only planet we know of that has life," said Alan Boss, a planet formation theorist at the Carnegie Institution of Washington in Washington, D.C.

Though other bodies in our solar system, such as Saturn's moon Titan, seem like they could have once been hospitable to some form of life, and scientists still have hope of eventually digging up microbes beneath the surface of Mars, Earth is still the only world known to support life.

"So far, we haven't found it anywhere else," said Alex Wolszczan of Pennsylvania State University, who co-discovered the first planets beyond our solar system. He agreed that life was Earth's single most impressive characteristic.

Ancient mineral reveals watery past.

An analysis of elements in ancient mineral crystals suggests liquid water existed on earth as long as 4.3 billion years ago, 100 million years earlier than previously thought.

No rocks have been found on earth older than 4 billion years, which has led many geologists to believe that for the first 550 million years of earth's existence, the world was literally hellish - preventing solid rock from forming.

But 25 years ago in a remote part of Western Australia, researchers found a few grains of zircon - a mineral that's extremely resistant to chemical changes - that were older than 4 billion years old.

In 2001, Professor John Valley from the University of Wisconsin-Madison and colleagues reported finding zircon that was 4.4 billion years old.

In subsequent experiments they analysed oxygen isotopes in zircons that suggested that by 4.2 billion years ago, the Earth was no longer hellishly hot, but at a low enough temperature that liquid water would have been present.

Ocean review finds warming on the rise.

clipper's remarks: It isn't just that ice is melting that is making the sea level rise, it is also the fact that water expands as it heats. With the volume of water in the ocean - 2/3 of the Earth's surface is covered with water, even a small temperature increase can have a dramatic effect. The way the expansion, and melting are factored into the research reports can make them a lot clearer, and more accurate.
While there are the best of intentions, regarding some kind of remedy, I don't remember anyone being able to literally turn back the tide, which seems like the bottom line.

A long-standing difference between climate models and observations has been resolved with researchers finding that the world's oceans have been warming faster than previously thought.

The paper, published today in Nature, shows ocean warming and thermal expansion trends for the past five decades are 50% larger than earlier previously estimated.

"For the first time, we can provide a reasonable account of the processes causing the rate of global sea-level rise over the past four decades - a puzzle that has led to a lot of scientific discussion since the 2001 IPCC report but with no significant advances until now," says CSIRO scientist, Dr Catia Domingues, from the Centre for Australian Weather and Climate Research.

Understanding how ocean warming and the resulting thermal expansion contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say.

A team of researchers has found how some reef fish use their fins to fly underwater, allowing them to survive in the sometimes cyclonic currents surrounding coral reefs.

The research, led by Dr Chris Fulton, from The Australian National University, appears in the journal Coral Reef.

Fulton says he first noticed the wing-like fins during surveys of coral reefs in Australia.

The wing shape allows fish such as parrotfish, wrasse and surgeonfish to fly through the water using a figure-of-eight pattern.

He says fish with wing-shaped fins keep them spread at all times and sweep in a figure-of-eight pattern that constantly generates thrust.

"They do this by inclining their fins at just the right angle to create lift from the water flowing over the fin, similar to the way air moves over the wing of a bird to propel them through their air," Fulton says.

Nanopaper soaks up oily spills

A mat of nanowires with the touch and feel of paper could be used to clean-up oil spills or as a low cost water filter, according to US researchers.

Oil and water may not mix, but they can be difficult to separate

The water-resistant nanopaper, which has the ability to soak up to 20 times its weight in oil, appears in this month's issue of Nature Nanotechnology.

Assistant Professor Jing Kong, a researcher at the Massachusetts Institute of Technology (MIT) and co-author of the paper, says the nanopaper is very similar to traditional writing paper.

"You can even print on it and cut it just like paper," he says.

Unlike normal writing paper, which is made from cellulose, nanopaper is made from solid potassium manganese oxide nanowires. Each nanowire is about 20 nanometers in diameter, and together they naturally clump together to form strands several centimeters long.

The process of making the nanopaper is the same one you would use to make [normal] paper
