Today, in the modern world of technology, many of us are aware of the fact that the marine life
is in great danger as intensive decline has been noticed in many places. The coral banks have
been markedly deteriorated due to climatic change along with the immoral human activities like
dumping the sewage waste into the sea water.
But nothing to worry much, as the good news arrives by a recent research which has been
conducted in Australia. Scientists have reported that there has been marked increase in the coral
growth in the region through the 20th century due to the increase in the temperatures. Research
has shown that this effect was more noticeable at the latitudes which are high and the ocean is
colder. These researches give a strong hint that the warming which is caused by us humans in
the form of carbon dioxide is in fact benefiting the corals in the region. This thing according to
Timothy Cooper is very much surprising as stated in a journal of science.
Extraordinary and unexpected clouds of methane gas which is a greenhouse gas and is 20 times more intoxicating than carbon dioxide gas has been found bubbling at the surface, by a few scientists who were there to explore and take survey in the Arctic Ocean.
The head of the Russian team who was surveying there was surprised by the extent and quantity if the methane gas. This team has been taking several surveys in the seabed of East Siberian Arctic Shelf off northern Russia for about 20 years. In an interview, Igor Semiletov who is working at the Russian Academy of Sciences said that he has witness such a thing for the first time in his work career, and he has never seen methane gas being released with such a force and large scale.

Everyday developments in the field of science and technology have become a routine in today’s world. Scientists and engineers are constantly working on making advancements in the innovations they have already developed. Recently the eminent scientists working at the Energy Department Lawrence Berkeley National Laboratory have recently achieved a remarkable success, which is related to energy. The development is basically a virus that helps to generate electricity. It’s a genetically persuaded virus to make such devices which will convert body’s movement into electricity.
These devices are as small as thin wafers can be attached to clothes or could be inserted within the shoes. According to the project chief investigator Seung Wuk lee, these small power generators are capable enough to as much electricity which could easily provide power for cell phones and other small gadgets like ipods and ipads etc.
This method of converting mechanical energy into electric which is known as piezoelectric is widely used in cars and many other processes. For example in cars we often see cigarette lighters and starters are making use of piezoelectric method in a way that we push the starter button and the grill generates small amount of current which later generates a spark and ignites the gas.
Normally inorganic ceramic materials were used as piezo generators, but for the first time scientists have successfully experimented using biological ad organic materials to create these devices which obviously have several advantages. Inorganic materials tend to produce several toxic byproducts as compared to the inorganic ones which are more environment friendly according to Dr.Lee.
According to reports given by Dr.Lee the Berkeley Lab initiated their research with a virus named M13, which is said to be nontoxic virus for human beings and natures and is very widely used in labs. A little modification was adopted in M13 which helped to boost the overall properties of piezoelectric. After that a very thin film as thin as a paper was created and was placed in between two plates of gold plated electrodes. After that pressure was applied this was more than enough to light up an LED.
Dr.Lee further stated that these devices will not be soon available in the market, as we are still in the phase of investigations and discovery level. In case the research is successful, it might take another five to ten years to power these microelectronic devices. These devices will also be helpful to power medical devices like pacemakers etc.
Axion International, a company from the New Jersey founded in 2007, has devised a new technique of recycling old plastic items. This innovative technique is to construct different building material like bridges etc by using discarded detergent containers, plastic bottles, milk carton and several other related things. This building material will be strong enough to replace steel, iron and concrete as it will be a mixture of frayed plastics and some amount of fiberglass. This technology has first time been introduced by the professor of engineering Thomas Nosker at Rutgers.
Plastics have a quality that they don’t degrade. Buried in the ground for centuries may even not decay them completely. Many people for the same reasons melt plastic and use it as boards at beech house decks or many make out clothing material by twirling it up. Continue reading
Natural gas drilling in NewYork State, which is to take place next year, is suffering from criticism by various environmental groups. They are demanding for strict regulations for it. Mark Ruffalo, a famous activist is in favor of the complete ban of this drilling process. He is of the opinion that the nation should meet it needs from renewable energy resources, rather than relying on fossil fuel.
Famous actor, director and screenplay writer, Mark Ruffalo is roaming around the Newyork state using his status to campaign for a ban on hydrofracking. Horizontal hydraulic fracturing is a process in which water and some others chemicals are enforced into a fine grained rock under the ground, in order to obtain gas. Environmental experts are of the opinion that this process of drilling may impart negative impacts and certain risks to the aquifers and may also affect the value of the air. Continue reading
UK canned seafood manufacturer John West, once branded ‘John Worst’ by Greenpeace for its poor record on sourcing tuna responsibly, will today launch a five-year plan to source the depleted fish stock more sustainably and will announce the launch of a new range of pole and line sourced tuna products.
A Hampshire-based cosmetics firm has installed a solar photovoltaic (PV) system on its 55,000 square roofspace in the latest demonstration of the manufacturer’s commitment to going green. “w3bs of DP”
Conservation group WWF let timber companies use its panda brand logo while they were razing some of the world’s most biologically rich rainforests or trading in potentially illegally sourced timber, according to the investigative group Global Witness.
A new guide released this week by nonprofit organisation the Carbon Trust encourages businesses to opt for sustainable, high-efficiency refrigeration equipment and methods, claiming that they could save 20 per cent on energy bills by doing so.
Wirrral-based green energy products manufacturer Stiebel Eltron UK is forecasting a 40 per cent growth in turnover in 2011, as it announces a second major contract with a supplier this year.
