Children Science Congress begins with interactive dialogue of Prof. Yashpal

It was a real feast of knowledge for students as well as the audience at the inaugural ceremony of the Children Science Congress when Prof. Yashpal invited school students to the dais and explained the mystery of the sound of clapping

Science Congress is an Important Platform for Bringing

The Indian Science Congress is an annual session generally held from 3rd to 7th January among the scientists of different disciplines, science managers, policy makers and the general public to give a stronger impulse and a more systematic direction to the scientific inquiry, to promote the interaction of societies and individuals interested in science in different parts of the country and to obtain a more general attention to the objects of pure and applied sciences.

CHILDREN SCIENCE CONGRESS AT GUJARAT SCIENCE CITY

About 250 students from all over the country will participate in children science congress at the science city starting from January 3. The congress, a part of the Indian science congress, will be a unique event for children of Gujarat, to interact with the selected students from different parts of the country. The Children Science Congress is a part of the 92nd Indian Science Congress which is being held this year in Ahmedabad.

Tsunami: A new name in earthquake disaster !

For thousands of fisher folk, who had gone like every morning into the sea, it was again the same story - suddenly being caught in a phenomenon, tsunami, which struck India for the first time in recorded history.

Winning the war against genetic diseases

ONE OF the potential benefits of Human Genome Project is in the field of gene therapy. Each of us carries about half a dozen defective genes. We remain blissfully unaware of this fact unless we, or one of our close relatives, are amongst the many millions who suffer from a genetic disease. About one in ten people has or will develop at some later stage, an inherited genetic disorder, and approximately 2,800 specific conditions are known to be caused by defects (mutations) in just one of the patient's genes. Some single gene disorders are quite common-cystic fibrosis is found in one out of every 2500 babies born in the Western World and in total, diseases that can be traced to single gene defects account for about 5 percent of all admissions to children's hospitals.
Most of us do not suffer any harmful effects from our defective genes be cause we carry two copies of nearly all genes, one derived from our mother and the other from our father. The only exceptions to this rule are the genes found on the male sex chromosomes. Males have one X and one Y chromosomes, the former from the mother and the latter from the father, so each cell has only one copy of the genes on these chromosomes. In the majority of cases, one normal gene is sufficient to avoid all the symptoms of diseases. If the potentially harmful gene is recessive, then its normal counterpart will carry out all the tasks assigned to both. Only if we inherit from our parents two copies of the same recessive gene will a disease develop.

Toxic wastes as fertilisers Poisoning or nourishing ?

Wastelands: The threat of toxic fertilisers," released recently by the national and state Public Interest Research Groups (PIRG) of the United States, reveals that a total of 22 toxic metals, including arsenic and lead , were found in the common fertilisers in the US. Fertiliser products become contaminated when manufacturers buy toxic wastes from industrial facilities to obtain low cost plant nutrients such as zinc or iron.


Human Genome Project A special Report

The complete set of instructions for making an organism is called its genome. It contains the master blueprint for all cellular structures and activities for the lifetime of the cell or organism. Found in every nucleus of a person's many trillions of cells, the human genome consists of tightly coiled threads of deoxyribonucleic acid (DNA) and associated protein molecules, organized into structures called chromosomes.
Some DNA details : If unwound and tied together, the strands of DNA would stretch more than 5 feet but would be only 50 trillionths of an inch wide. For each organism, the components of these slender threads encode all the information necessary for building and maintaining life, from simple bacteria to remarkably complex human beings. Understanding how DNA performs this function requires some knowledge of its structure and organization.


Drink water, keep heart healthy

Researchers at Loma Linda University in California found that people who drank at least five glasses of water each day were less likely to die from a heart attack than those who drank two or fewer glasses per day. In contrast, people who drank a lot of other fluids were more likely to die from heart attack than those who drank less, with high levels of non water drinking in women associated with a more than twofold increased risk of death

How sound becomes electric

SCIENTISTS FROM THE Centre for Hearing and Balance at Johns Hopkins have discovered how tiny cells in the inner ear change sound into an electrical signal the brain can understand.

Their finding, published in a recent issue of Nature Neuroscience, cound improve the design and programming of hearing aids and cochlear implants by filling in a 'black hole' in scientists understanding of how we hear, say the researchers.

"Sound itself is mechanical, a wave that moves, just like the ripples fanning out from a pebble dropped in a lake," says Paul Fuchs, professor of otolaryngology at the Johns Hopkins School of Medicine. "When the inner ear detects this wave, a burst a nerve sends an electrical signal to the brain that carries information about the original sound. But the nature of the chemical burst has been a mystery until now."


Vascular surgeon with a vision

Many of the serious illnesses, be it heart attack, stroke or problems, have their origin in blood vessels. But the surgeon who deals with the blood vessels, the lifeline of the human body, is the least known.
Dr. S.A. Hussain is not angry with this public ignorance or the unfavourable treatment the surgeons of vessels, called vascular surgeons, receive. Instead, he is on a campaign to sensitise people and to improve public health.


New asthma treatment

Three potent proteins of the immune system, evolved to purge us of intestinal parasites, now often launch misguided attacks in our airways, triggering the congestion of asthma that leaves millions gasping for air.
By studying the genetic machinery that controls production of these immune soldiers called cytokines, a team of scientists has demonstrated a potential strategy to silence their misfiring and quell the asthma response.

Mechanical heart moves ahead

A daring experiment testing a self- contained mechanical heart offers new hope for thousands with failing heart, many of whom may die while waiting for transplants.

First genetically altered babies born

The world's first genetically modified babies have been born after women unable to conceive naturally underwent a revolutionary new fertility treatment used by scientists at a New Jersey medical facility, a researcher said this week.


Low Cost Cholera Vaccine

Trials of a cholera vaccine manufactured in Vietnam at a cost of about only 20 US cents a dose have produced encouraging results, especially for children, an international team of researchers reports in the World Health Organisation's latest issue of The Bulletin. A team headed by Professor Dang Duc Trach at the National Institute of Hygiene and Epidemiology in Hanoi concluded that the vaccine was "safe and immunogenic" and "could elicit robust immune responses".

Planning for safer structures
ARTHQUAKES don't kill, buildings do. This is an adage that has been proved beyond doubt in Gujarat. So what is it that we can do to make our cities, towns and villages safer?

Prof Housner says a great disaster may occur if three conditions are net: (a) an earthquake of sufficiently large magnitude, (b) occurrence of the earthquake does enough to a population center and, (c) the population center having buildings which are not earthquake resistant.

When all these conditions are met catastrophe occurs as in Gujarat. But what can we do to make sure that this is not repeated. Obviously the first condition is not in our control, and when we have chosen to consciously from large habitation is risk zones, neither is the second. The third is the only condition that we can hope to ever influence.

We must first build safer new structures. And since no building can be made safe against all earthquakes, the best bet is to conform to the prevailing structural codes that define the provision required according to the risk zone in which the structure is to be located. Secondly, we must retrofit old structure that do not confirm to the identified risks.

Elaborate codes are available that recommend ways to strengthen existing structures, both engineered and non engineered. In fact Indian codes are fairly elaborate and one exists even for mud structures.

For this one immediate step would be to make people aware about the need to use professional help get the law to clearly define who is competent to design the safe building.

Together with this architects must be trained to develop a conceptual under standing of building safe structures. But considering the availability of the number of professionals competent to do the job, simple guidelines must be made available to users to build smaller safe structures on their own.

It is essential that construction workers be taught the basic of building safe structure this means that where available, the elaborate codes for non-engineered structure must be interpreted, and where non applicable new guidelines must be developed. After all, in a large number of cases it is these masons and workers who are the only technical help available to users.

One another angle that we seem to be missing out is that of coordinated planning in a city. Recent earthquakes, even in developed countries have amply demonstrated that the civic infrastructure is the first casualty.

Planners must take in to consideration that as we come to depend more on large flyovers and bridges in a city, the transport infrastructure can collapse and disrupt relief efforts: We are now laying gas pipelines in cities, a fire has already take place when one government agency, during its digging operation, punctured a gas pipeline. Any damage to these pipelines in case of an earthquake can add another significant dimension to the problem .

Critical lifelines such as power plants, transmission equipment, water treatment plants, the pipelines, the underground metro public structure such as the hospitals, fire station and various control rooms must be planned to withstand risks higher than those application for other structures.

A workable strategy for disaster preparation that relies on the skills and strengths of people themselves, both those technically qualified and otherwise, is essential maybe we can learn lessons from Japan, where being prepared for earthquakes is part of the country's life and culture.

The problem today is not the lack of codes. In fact there are many codes and provisions that are today define in many different documents and subdocuments, which are regularly updated. The problem is that these are difficult to keep track of. What could held considerably in improving their implementation is for them to be brought together in one publication, which is revised as often as necessary.
