SCIENCE UPDATES

1.Growth of Cities Endangers Global Environment, According to New Analysis
The explosive growth of cities worldwide over the next two decades poses significant risks to people and the global environment, according to a meta-analysis published August 19 in PLoS ONE.
2.Virus Uses 'Swiss Army Knife' Protein to Cause Infection 
In an advance in understanding Mother Nature's copy machines, motors, assembly lines and other biological nano-machines, scientists are describing how a multipurpose protein on the tail of a virus bores into bacteria like a drill bit, clears the shavings out of the hole and enlarges the hole.
3.Spoilt Food Soon a Thing of the Past?
Unwanted bacteria, yeasts and moulds can cause major problems for the food industry as well as consumers. Norwegian researchers have developed new methods to identify potential sources of contamination.
4.Four-Year-Olds Know That Being Right Is Not Enough
As they grow, children learn a lot about the world from what other people tell them. Along the way, they have to figure out who is a reliable source of information. A new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, finds that when children reach around 4 years, they start noticing whether someone is actually knowledgeable or if they're just getting the answers from someone else.
5. New Treatment Approach for Alzheimer's Disease: Researchers Plan to Use Specialized Cells of the Immune System
A research team at Charité -- Universitätsmedizin Berlin and Universitätsklinik Freiburg has documented how the immune system can counteract the advancement of Alzheimer's disease. In a newly published paper, they showed that certain scavenger cells in the immune system, called macrophages, play a key role in this context. Furthermore, they were able to demonstrate how special cell-signaling proteins, called chemokines, mediate the defense process.
6. Nature Reaches for the High-Hanging Fruit: Tools of Paleontology Shed New Light On Diversity of Natural Plant Chemicals
In the first study of its kind, researchers have used tools of paleontology to gain new insights into the diversity of natural plant chemicals. They have shown that during the evolution of these compounds nature doesn't settle for the 'low-hanging fruit' but favours rarer, harder to synthesise forms, giving pointers that will help in the search for potent new drugs.

Biologists Confirm Sunflower Domesticated in Eastern North America
 New genetic evidence presented by a team led by Indiana University biology doctoral graduate Benjamin Blackman confirms what is now the eastern United States as the single geographic domestication site of modern sunflowers. Co-authors on the findings published this week in Proceedings of the National Academy of Sciences include Blackman's advisor, IU Distinguished Professor of Biology Loren H. Rieseberg, and four others from Rieseberg's lab, as well as collaborators from Universidad Nacional Autonoma de Mexico and the University of Cincinnati.
Catalyst That Makes Hydrogen Gas Breaks Speed Record
 Looking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at 100,000 molecules of hydrogen gas every second.
Enzyme Found Disrupting Nerve Cell Communication in Alzheimer's Disease
Alzheimer's disease is characterized by abnormal proteins that stick together in little globs, disrupting cognitive function (thinking, learning, and memory). These sticky proteins are mostly made up of beta-amyloid peptide. A better understanding of these proteins, how they form, and how they affect brain function will no doubt improve the diagnosis and treatment of Alzheimer's disease.
DNA Building Blocks Can Be Made in Space, NASA Evidence Suggests
NASA-funded researchers have evidence that some building blocks of DNA, the molecule that carries the genetic instructions for life, found in meteorites were likely created in space. The research gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by meteorite and comet impacts assisted the origin of life.

INAUGURATION REPORT

The inauguration of science club for the academic session 2011-12 was held on wednesday 3.8.2011. The ceremony started with invocation to god almighty.It was followed by welcome address by Mrs.Beena Mathews
I\C science club. She briefed out the activities already conducted by the club and reminded the members to make use of all opertunities given to them during club activities.
The ceremony was inaugurated by Sri PP.Maniyappan,Principal KV Payyanur by lighting the traditional lamp.Principal Sir in his inaugural address mentioned about the importance of science club.He specified that each science club memeber should "think beyond limit" and bring out innovative ideas. He appriciated the efforts taken up by science club members and suggested that club activities should be arranged beyond the school campus also.He assured  financial assistance for these activities with in permissible limit.
Then the chief guest distributed prizes for poster making competition held on 27 July. The winners among juniors (VI-VIII.)were 1st.   Swetha(VIII-A)
                                   2nd  Anjana.A(VII-B)
                                   3rd  Anjana Rajan(VII-B)
Seniors(IX-XII)were   1st    Roshni(XI-B)
                                   2nd  Arjun NV(X-A)
                                   3rd Amrutha(XII-A)
Finally Master Gaurav X-B secretary science club expressed vote of thanks.After the programme refreshments were distributed to the club members and various teachers.

SCIENCE UPDATES

1.Revolutionary Biodegradable Pellet Targets Glue Ear Infection
 A revolutionary biodegradable pellet which slowly releases antibiotics into the middle ear could transform the lives of thousands of children who suffer from glue ear. 
2.Lattice of Magnetic Vortices: Researchers Find Magnetic Skyrmions in Atomically Thin Metal Film 
Physicists at Hamburg and Kiel University and the Forschungszentrum Jülich have found for the first time a regular lattice of magnetic skyrmions – cycloidal vortex spin structures of exceptional stability – on a surface. This fascinating magnetic structure was discovered experimentally at the University of Hamburg by spin-polarized scanning tunnelling microscopy and imaged on the atomic scale. 
3. First True View of Global Erosion
Every mountain and hill shall be made low, declared the ancient prophet Isaiah. In other words: erosion happens. But for the modern geologist a vexing question remains: how fast does this erosion happen? 
 4.Watermark Ink' Device Identifies Unknown Liquids Instantly
Materials scientists and applied physicists collaborating at Harvard's School of Engineering and Applied Sciences (SEAS) have invented a new device that can instantly identify an unknown liquid.
