The opah Lampris guttatus has a global range that includes the southern waters of Australia and swims at depths between 10 and 450 metres.
As the warm blood leaves the core and travels toward the surface of the gills, it transfers its heat to the cold blood that is travelling back from the gills where it has absorbed oxygen from the water.
and says the exchange stops the heat from nearing the gill surface where it would be cooled by the water flow through the gills.
insulating them from the frigid water. The researchers found the opah was able to maintain body warmth of about 5 degrees Celsius higher than the surrounding water temperature."
"The fish aren't warming up to the same degree as animals and birds,"says Wegner."
"If the opah was swimming in waters at 10 degrees Celsius than its body temperature would be about 15 degrees Celsius."

A team led by Cockrell School of engineering associate professor Christopher Ellison found that a synthetic coating of polydopamine--derived from the natural compound dopamine--can be used as a highly effective, water-applied flame retardant for polyurethane foam.
The polydopamine was coated onto the interior and exterior surfaces of the polyurethane foam by simply dipping it into a water solution of dopamine for several days.
The compound is repelled by water at neutral ph, which allows it to easily diffuse through cellular and nuclear membranes,
#Innovative Bioelectronic Nose Smells Traces of Bacteria in Water A bioelectronic nose that mimics the human nose can detect traces of bacteria in water by smelling it, without the need for complex equipment and testing.
and it can detect tiny amounts of contamination in water, making it more sensitive than existing detection methods.
There are two main problems caused by bacteria and other microbes in water: they can make the water toxic,
and make it smell bad. At high concentrations, bacteria can be toxic in drinking water. But at lower levels virtually undetectable by current culturing techniques they can cause an ff flavor,
even if the water isn toxic, you don want to drink it. We wanted to develop a way to detect
so people are happy to drink water. raditionally, water was tested for contamination with bacteria by taking a sample
and trying to grow the bacteria in the lab . When the bacteria grow, scientists can count the number of colonies
and calculate the concentration of bacteria in the water. Another approach is to detect the smells directly;
compact device for testing water that is suitable for using on-site. In addition to contamination of drinking water bacteria and other microbes can also contaminate rivers and lakes for example, the algal blooms in Hong kong.
Catching this kind of contamination early means it easier to control. We have five senses sight, hearing, touch, smell and taste.
Bacteria that contaminate water give off particular smells that are associated with a handful of smell molecules.
The new nose-like device can detect these smells at very low concentrations of just 10ng per liter of water.
And on top of that was water, into which the scientists injected the molecules that spontaneously form the toxic aggregates."

They are sharing concepts and ideas with researchers across the Pacific ocean. In Asia, Japan aerospace exploration agency (Jaxa) is also working on a hypersonic airliner called Hytex intended to cross the Pacific ocean in two hours at speeds of Mach 5. Both Lapcat-II
and Jaxa are part of a hypersonic knowledge-transfer project between Europe and Japan called Hikari.
If the hydrogen can be sourced from natural gas, instead of from the electrolysis of water, the airfare tickets of a hypersonic trip could drop to about half the price of a business-class ticket.
They are able to grow in seawater, and their strong, stilt-like root systems allow them to thrive in swamps, deltas or coastal areas.
"After the 2004 (Indian ocean) tsunami, it became evident-particularly in Sri lanka which was impacted severely-that those villages that had suffered intact mangroves significantly less damage than those that did not.

the water-loving part is separated from the water-fearing part. When this happens on a nanoparticle,
and therefore clump together to minimize contacts with water, Bertrand explained. From there, these larger aggregates can easily be retrieved through filtration or sedimentation,
with more than 95 percent of the nanoparticles removed from the water. When the nanoparticle loses its protective layer,
polymers are released into the water. While the polymer released (polyethylene glycol) is recognized as safe and used in various food, pharmaceutical and cosmetics products,
Still, even with the small amount of material released into the water Bertrand nanoparticles have compared benefits with current purification processes.

#Micro motors could soak up CO2 pollution in the oceans, study finds Machines that are smaller than the width of a human hair could one day help clean up carbon dioxide pollution in the oceans,
new research has found. Nanoengineers at the University of California, San diego, have designed enzyme-functionalized micromotors that rapidly zoom around in water,
remove carbon dioxide and convert it into a usable solid form. The proof of concept study represents a promising route to mitigate the build up of carbon dioxide,
In their experiments, nanoengineers demonstrated that the micromotors rapidly decarbonated water solutions that were saturated with carbon dioxide.
Within five minutes, the micromotors removed 90 percent of the carbon dioxide from a solution of deionized water.
The micromotors were just as effective in a sea water solution and removed 88 percent of the carbon dioxide in the same timeframe."

which speeds up the reaction between carbon dioxide and water to form bicarbonate. Calcium chloride which is added to the water solutions,
helps convert bicarbonate to calcium carbonate. The fast and continuous motion of the micromotors in solution makes the micromotors extremely efficient at removing carbon dioxide from water,
said researchers. The team explained that the micromotors'autonomous movement induces efficient solution mixing, leading to faster carbon dioxide conversion.
To fuel the micromotors in water, researchers added hydrogen peroxide, which reacts with the inner platinum surface of the micromotors to generate a stream of oxygen gas bubbles that propel the micromotors around.
When released in water solutions containing as little as two to four percent hydrogen peroxide the micromotors reached speeds of more than 100 micrometers per second.
As a next step, researchers are planning to make carbon-capturing micromotors that can be propelled by water."
