Nokia launched four new models cheaper mobile phone, and a dynamo powered mobile phone charger homemade bike first, to help protect its dominant market share in a market that is growing.

Nokia controls over 50 percent of mobile phone sales in India and Africa and has strong positions in new markets.

“Tens of millions of these products will be sold, but the competition becomes more intense because the Chinese vendors aggressively targeting the low cost,” said Ben Wood, research director at CCS Insight, told Reuters.

“All the focus on the failure of the smart phone and forget that Nokia is a force in the entry-level product.”

Nokia has to compete with other competitors like Apple and RIM in the high-end market, but its failure to offer smart phones have hurt its stock price over the last few months.

Four new mobile phone models sold cheap are including service and government tax subsidies. Cell phone prices are ranging from 30 euros (36.9 dollars) to 45 euros.

Two new phones with the cheapest price of 30 euros, allows you to use two different SIM cards – to help share the telephone communication between family members or friends.

Nokia also introduced the battery charger that adopts the workings of a bicycle dynamo is designed for consumers with access to electricity is limited and may be sold for 15 euros, depending on the market, at the end of this year, said a company spokesman.

For the first time, researchers showed that molecules called antibodies non biological plastics can work like a natural antibody.

In tests on animals, plastic particles bind and neutralize toxins found in bee stings, toxins and antibodies and then washed to the liver, the same path through which the natural antibody.

The researchers are now developing antibodies to various targets in the plastic sphere more extensive disease in the hope of expanding the availability of antibody therapy, which is currently very expensive.

For more than 20 years, biochemists have attempted to mimic the ability of antibodies “to zero” in their targets, as part of a strategy to make more effective, less expensive therapies, and diagnostics.

“The antibody currently produced on an industrial scale this time is very important because they are so very expensive,” said Kenneth Shea, professor of chemistry at the University of California, Irvine, in Technology Review.

That’s because the antibodies are grown in animals; their complex molecules that can not be made in a test tube, or even by bacteria. And an antibody, like other proteins, is very fragile. Even under refrigeration, they only hold a few months.

Shea’s and other questions within 20 years, he said, “whether it is possible to be designed to be cheap, starting materials a biotic?” Antibodies can be made cheap plastic and then placed on a shelf, in theory, survive for years.

Sperm whale or physeter macrocephalus is one of the biggest animals in the sea. Its’ dung may help the oceans absorb carbon dioxide, CO2, scientists stated. Australian research team considered the Southern Ocean whale sperm release 50 tons of iron annually. That waste is to stimulate the growth of tiny sea plants – phytoplankton – which absorb CO2 during photosynthesis.

This process resulted in the absorption of about 40 000 tones of carbon – more than twice the amount released by the whale to breathe, said the research results. The researchers note in the journal Proceedings of the Royal Society B that the process also produces more food for the whale, estimated to number 12,000. Phytoplankton is the basis of marine food web in this hemisphere, and very small plant growth is limited by the amount of available nutrients, including iron.

During approximately the last decade, many scientists are experimenting with iron poured into the sea deliberately to deal with climate change. Not all the experiments were successful. Largest experiment, the expedition Lohafex Germany, devoting six tons of iron into the Southern Ocean in 2008, but found no increase in release of carbon (carbon uptake) in a sustainable manner.

Despite 40 000 tons of carbon less than 1/1.000 annual emissions from burning fossil fuels, the researchers noted that the sum total of the whole world may be more substantial.

Sperm whale population is estimated at several thousand in all oceans, although the species is known difficult to calculate.

Scarcity of iron is limiting phytoplankton growth in many areas outside the Southern Ocean. Thus the whale dung becomes fertilizer for the plants in several parts of the world. According to this view, sperm whales do not eat and throw dirt at the same place. If that happens on the contrary, they may absorb and produce the same amount of iron.
Sperm whales eat their food, mainly squid, deep sea, and throw dirt in more shallow places where phytoplankton can grow thanks to access to sunlight.

Iron producing here in the end is good for the whale said the researchers – led by Trish Lavery from Flinders University in Adelaide. Phytoplankton are eaten by tiny sea animals – zooplankton – which is then eaten by larger creatures which then may be eaten by a whale. Read the rest of this entry »
