Well i was going thru a page which contains poem and i found out that, one of my lecturer wrote these two amazing poems and i would like to share with u guys..

From Death to Birth:

Have you ever experienced the pain and pleasure of Birth?
Though it is painful
Accepted and deliveries are continuing!!
Every life starts with pains and expectations
Only YOU make the life meaningful
Weather worries or wonders left to you
If the Sun is not there, moon will substitute. . ..
The Moon is not there, Stars will substitute. . .
Stars are not there, you are there to find an alternate!!
Every walk in your life will decide your future
Don't save only money for your future. . ...
Save good people,hearts,habits,attit
udes love,
They will come up to your death and grow after it
Beyond death there is a life an eternal life
Which you can achieve by Love and affection
By surrendering to the GOD
Not to follow any religious measures but to
Think, plan, do, check and act
For right things in a right way at a right place

Sivaramakrishnan Sudhakaran

Live for the Love
Inspired ever...
Expired never.
Touches of the love
Things of glamour
Senses of affection
Smells of flowers
ever green enjoyments.....
Let us live for the love
Not only for this...
Ever lasting understanding
Never loosing tolerance
Foresight of forgiveness
Insight of situations
Excite of emotions
Sharing with dedication
Caring with devotion
Enchanting Love
with uncomparable care
so let us LIVE for the LOVE

India is 'thailand' to Asia, say scientists


India is 'thailand' to Asia, say scientists
By Raja Murthy

MUMBAI - Since "thai" means "mother" in classical Tamil, the language of the south Indian state of Tamil Nadu and said to be the oldest living language in the world, "thailand" means motherland. However, India could be an ancient "motherland" of Thailand and Asia in a more literal sense, according to a new investigative study, "'Mapping Human Genetic Diversity in Asia".

The findings, from an unprecedented collaboration of over 80 researchers and 40 scientific institutions across Asia [1], reveal a twist in the history of human migration. It points to India, then Thailand and Southeast Asia, being the ancestral home to most Asians.

The paper, titled "Mapping Human Genetic Diversity in Asia", published in the Science journal issue of December 10, is the firstof its kind on Asian populations. Undertaken by the Singapore-based Human Genome Organization (HUGO), the study follows earlier multiple genetic studies on European populations.

The HUGO Pan-Asian SNP Consortium, as the project is called, overturns accepted knowledge that multiple migrations of populations directly went to East Asian countries from Africa, nearly a hundred thousand years ago.

According to the new study, Dravidians - the race of people who inhabit south India, including Tamils - could be a common ancestral link to most modern-day Asians.

The news would be an early mega Christmas gift to chauvinistic Dravidian political parties, such as the Dravida Munnetra Kazhalgam (DMK, or the Dravidian Progressive Party) and its 85-year-old chief, Muthuvel Karunanidhi, currently ruling Tamil Nadu.

Historically, Dravidians are considered India's original settlers. A more disputed theory says Dravidians were the original inhabitants of the Indus Valley civilization. Aryan invaders from Europe pushed them south of the Vindhaya Mountains into the Deccan Plateau in southern India, over 3,500 years ago.

But while the new HUGO study could support anthropological knowledge of Aryans invading India, the findings also say modern India shares a closer genetic ancestry with Europe than with Asia. "Most of the Indian populations showed evidence of shared ancestry with European populations," observed page four of the six-page report in Science.

"The current Indians received more genetic input from Aryan invasions which brought more Caucasian genes," says Dr Edison Liu, executive director at the Genome Institute of Singapore and president of HUGO. "So in fact, excluding modern-day Indians, there is clear indication that we are all genetically related in Asia."
Modern-day Indians, Liu says, would mean those in post-Aryan India. In effect, the new HUGO study could point to India having a large Eurasian population, like Russia.

"We have redefined the genetic history of Asian migration," declared Liu. "Previously, it was thought - because of archaeological, anthropological, and limited genetic data - that Asia was populated by two waves of migration. One wave was from Southeast Asia, called the Southern route, and the second from Central Asia, called the Northern route."

Liu informed Asia Times Online that the HUGO Pan-Asian SNP Consortium findings now point to a single wave of migration from Southeast Asia. "This places disparate ethnic groups like the Negritos [in the Philippines], Dayaks [in Borneo, Indonesia] etc. within the Asian fold," says Liu. "The reconstruction is out of Africa to India."

Caucasians and Asians were then divided, with the Caucasians moving to the Levant, or the Asian side of the Mediterranean Sea. The people wave continued to India, and then to Thailand, Malaysia, Indonesia and Philippines. From Southeast Asia, settlers migrated to other parts of Asia, including China.

If the study is accurate, the Han Chinese - the single-largest ethnic group in Asia and in the world - have ancestral linkages to southern China, northern Thailand and earlier in India.

Sections of the Indian media highlighted the Chinese angle in the HUGO report. The Times of India, with a readership of 13.3 million, headlined its report as "Ancestors of Chinese came from India: Study". The Mumbai-based Daily News and Analysis went further, calling its report "The Chinese evolved from Indians: Study".

So do Chinese have Indian ancestors? "It is probably more correct to say that Dravidians [in southern India] and Chinese had common ancestors, than to say that Chinese ancestors originated in India," said Liu, who was born in Hong Kong and emigrated to the United States in 1957.

"What we are seeing is the transit of our ancestors in their travels out of Africa through India and into Southeast Asia and North Asia," Liu explained. "Along the way, they deposited progeny that later expanded, or contracted."

Benefits from the findings include unified health solutions across Asia. A common ancestral link enables clinical trials for medicines that would be applicable across a wider region. Liu has worked on leukemia and breast cancer research at the University of North Carolina at Chapel Hill.

"This research is also significant for furthering the research in medicine," Samir Brahmachari, director general of the New Delhi-based Indian Council of Scientific and Industrial Research, told Indian media.

"The findings have great potential for collaboration with these countries in finding treatment to many diseases like flu, HIV and other pandemics," said Brahmachari, who is also a member of the 18-person HUGO governing council, and a professor of molecular biophysics and genetic engineering.

"The paper not only presents a fantastic genotype database but also provides vital clues to scientists of diverse fields - from linguistics to archeology to human genetics," says Vikrant Kumar, a post doctoral fellow of the Genome Institute, Singapore, and an investigator in the study.

Kumar, who earned his doctorate from the University of Calcutta, calls this the only effort of its kind where 73 populations scattered across 10 Asian countries are studied together. About 2,000 samples covering almost the "entire spectrum of linguistic and ethnic diversity" were genotyped for about 50,000 single nucleotide polymorphic markers, [2] he said.

Apart from redefining the migratory origins of Asian people, the HUGO project marked a new high in pan-Asian scientific collaboration. "This study was very unusual," Liu says. "Perhaps the proudest achievement was that 10 Asian countries mounted this study on our own steam, funded and completed it internally, with each member working as equal partners."

Liu, whose academic career includes stints at Washington University, Stanford University, University of California and University of North Carolina, calls this study a "milestone not only in the science that emerged, but the consortium that was formed. We overcame shortage of funds and diverse operational constraints through partnerships, good will, and cultural sensitivity."

One of the hurdles was the disparity in technological access among the project team in various countries, with their varying access to expensive technologies. The problem was resolved by developing a host-guest structure, in which the technologically better off countries hosted working scientists with lesser technology access.

"We transferred technologies, expanded capabilities, forged friendships and now have an Asian scientific network of considerable worth," says Liu, a nice enough initial outcome of a project that found a common ancestral link to Asians.

Notes
1. Apart from over 80 individual researchers and scientists, the project involved 40 leading scientific organizations in Asia. It included Malaysia's Human Genome Center in Kelantan; India's Council for Scientific and Industrial Research in New Delhi; Thailand's National Center for Genetic Engineering and Biotechnology in Pathumtani; the Korean BioInformation Center in Deajeon; the University of Philippines in Manila; Taiwan's Institute of Biomedical Sciences; the Genome Institute of Singapore; Japan's National Institute of Genetics and the Chinese Academy of Medical Science.
2. A genetic marker, a gene or a known DNA sequence in a chromosome (a chromosome is a DNA unit found in cells), can be detected in the blood and are generally used to see if an individual or a group are vulnerable to a particular disease. A genetic marker may be a short DNA sequence (single nucleotide polymorphism or SNP), or a long DNA sequence.

The shorter SNP (pronounced snip) - used in this study - refers to a variation of genetic traits within an individual or a group. The study used 54,974 SNPs from 1928 persons representing 73 Asian populations. SNPs are the most frequent type of DNA variation. The HUGO study used the 'Affymetrix GeneChip Human Mapping 50K Xba Array' technology to analyze SNPs. The Affymetrix technology is available to scan SNPs of various densities, from 10,204 SNPs to a million.

How Bacteria Nearly Destroyed All Life

This is a classic Damn Interesting article that originally appeared on 08 September 2006.

CyanobacteriaAbout two and one-half billion years ago, life on Earth was still in its infancy. Complex organisms such as plants and animals had not yet appeared, but the planet was teeming with microscopic bacteria which thrived in the temperate and nutrient-rich environment. Greenhouse methane lingered in the atmosphere and trapped the sun’s warmth, creating a climate very accommodating to the stew of microbes life that made their home on primitive Earth.

But a billion years of bacterial evolutionary progress was soon stunted by a catastrophic global event. Geologists find no signs of a great meteor impact nor a volcanic eruption, but they have uncovered the unmistakable geologic scars of rapid worldwide climate change. Average temperatures, which were previously comparable to our present climate, plummeted to minus 50 degrees Celsius and brought the planet into its first major ice age. This environmental shift triggered a massive die-off which threatened to extinguish all life on Earth, and paleoclimatologists have good reason to believe that this world-changing event was unwittingly caused by some of the planet’s own humble residents: bacteria.

The period in history is known as the Paleoproterozoic era, and prior to that time the Earth’s ecology and environment were significantly different. The iron-rich waters of the oceans lent them a green tint, and the atmosphere was comprised of gasses other than oxygen. Although oxygen atoms were abundant, such as those found in water molecules, unbound oxygen was extremely rare. The sea was host to a plethora of anaerobic microorganisms, but there were also a few members of a newly evolved variety: a blue-green algae known as cyanobacteria. These adapted bacteria were the first to use water and sunlight for photosynthesis, producing oxygen as a by-product of their metabolism.

The cyanobacteria were a struggling minority at first, but scientists believe that these new microbes began to dominate with the help of meltwater from a few glaciers scattered across the young continents. These glaciers spent centuries scraping across the Earth collecting minerals, ultimately depositing their rich nutrient payloads into the oceans. The cyanobacteria flourished in the presence of the increased minerals, and the rapidly growing population was soon venting increasingly large amounts of its poisonous waste oxygen into the environment.

At first the damage was limited to the oceans’ ecosystems. The underwater oxygen began to chemically react with the abundant iron, eventually scrubbing the seas clean of the element through oxidation. The oxidized iron settled to the ocean floor, and the oceans’ green tint began to fade. This series of developments was nothing short of an ecological disaster– oxygen was poisonous to most of primitive Earth’s inhabitants, and many bacteria relied on the iron as a nutrient.

Once the oceans’ supply of iron was exhausted, oxygen began to seep from the sea into the air. With very little competition for resources, cyanobacteria continued to proliferate and pollute. The free oxygen they produced reacted with the air, gradually breaking down the methane which kept the Earth’s atmosphere warm and accommodating. It took at least a hundred thousand years– a short duration in geological terms– but the Earth was eventually stripped of her methane, and with it her ability to store the heat from the sun. Temperatures fell well below freezing worldwide, and a thick layer of ice began to encase the oxygen-saturated planet.

Not even cyanobacteria were immune to the effects of this major ice age. The traits which had once given them such an evolutionary advantage were creating an environment which was completely inhospitable, even for themselves. As the centuries marched on, the surface became increasingly cold and frozen, with the ice at the equator eventually reaching up to one mile in thickness: Earth was an ice planet. Thermal vents on the ocean floor provided pockets where some resilient bacteria managed to survive, and certain organisms which lived underground were insulated from much of the destruction; but these reservoirs of life were scarce. Almost every living thing on Earth died as a result of this massive bacteria-induced climate change, an event known as the oxygen catastrophe.

As told by the Earth’s ancient rocks, the story of the Paleoproterozoic era is one of near-extinction for all life on the planet. The rocks that lined the ocean floor during that period are layered with oxidized iron… the remains of the iron that was removed by the oxygen. Layers from previous periods have no such banded iron formations. The fossilized microbes in the rocks are also indicative of violent climate change.

The survivors of the oxygen catastrophe eventually adapted to consume the abundant oxygen and produce carbon dioxide. This greenhouse gas very gradually made its way into the atmosphere, increasing in concentration and nudging temperatures back into the hospitable range over millions of years. Had temperatures been slightly colder during the first major ice age– if Earth had been in a slightly more distant orbit– the planet would have remained an icy wasteland because the carbon dioxide would have frozen solid before it could promote the greenhouse effect.Banded iron formation, caused by layers of oxidized iron Temperatures reached as low as minus 50 degrees Celsius, and carbon dioxide freezes into dry ice at minus 78 degrees. Indeed it seems that life on Earth was spared by a very tiny margin.

Today all life on the planet can trace its lineage back to those few microorganisms which survived the great dying of 2,500,000,000 BC, and now cyanobacteria are among the most common bacteria on Earth. In the billions of years since the first ice age, the environment has been dramatically altered on numerous occasions by greenhouse gases which trap heat; by shifting tectonic plates which reroute ocean currents; by our sun’s varying radiation levels; and by volcanic activity which alters the atmosphere. But at least once in Earth’s long history, its own occupants seem to have unwittingly brought all life to the brink of extinction. The sun is warmer now than it was then, so such a “Snowball Earth” is a bit less likely to occur… but the cautionary tale catalogued in ancient rocks warns us that the environment is certainly not impervious to the actions of those living in it.

Single joys By SANDRA LOW




Not every single woman is sad, lonely and desperate. In fact, she could be far happier than her married sisters who are saddled with childcare, in-laws, third parties or a spouse she never really loved.

YOU’RE such a great girl, how come you’re single? Won’t you feel lonely when you’re old and don’t have children to look after you? Don’t worry ... you’ll get married someday.”

Over the years, my single friends and I (we’re in our 20s and 40s) have noticed something peculiar: married people are deemed to have achieved something more than the “doomed” singles. It is as if their lives are somehow complete with a partner.

Never mind that some of these couples are cheating on each other, live lives filled with tension and drama, or continue to have children even though their marriage is shaky. All that matters to society is that they have tied the knot.

Then again, how can we blame anyone when we have movie heroes telling their lady love, “You complete me” (Tom Cruise to Renee Zellweger in Jerry McGuire). The message driven home is that men and women are incomplete unless they have a special someone in their lives.

American psychologist and author Florence Falk posed a question in her powerful book, On My Own: “How is it that even the most apparently self-assured woman feels inadequate without a man?”

Falk believes that, encouraged by society, all too many of us assume a woman alone must be miserable or, worse, deserves to be.

Happily married girlfriends hope that you’ll find the love of your life while those who are unhappily hitched (or have partners) will sigh, “How lucky you are to be single, with your freedom and peace of mind, minus the hassle and heartache.”

I decided long ago that until I meet someone who “completes me” in the way I feel is right for me, I will not hold my breath or make a decision based on economics, convenience or fear.

A very sensible thirtysomething girlfriend (who divorced and subsequently found real love) says there are two things in life that you should never trust – electronics and men. Once a woman embraces this mantra, she will find partial nirvana, she believes.

Another intuitive fortysomething who is in her second marriage launches annual reminders to single friends to not settle for less than what they expect. Because once you do, there is a price to pay.

On the other hand, there’s the twentysomething who tells me that she jumps from one relationship to another because she’s too terrified of being alone.

Seriously, there are marriages or partnerships in which the couples are clearly meant for each other and they live happily together. Then there are those that are a stark reminder to the single woman that she may not be missing much.

Why do women end up being single?

Sometimes it’s by choice; sometimes she has no choice. And, like it or not, destiny has a hand in this.

To quote Carrie Bradshaw in the romantic comedy Sex and the City, “Some people are settling down, some people are settling and some people refuse to settle for anything less than butterflies.”

Settling means accepting a partner who is less than what one strongly believes in, in terms of intellectual compatibility, sense of responsibility, habits, attitude, morality and maturity.

There is no such thing as a perfect relationship, but if a woman settles solely because of her fears and insecurities, there will be consequences.

A woman may not choose to settle down because she does not want to make use of a man whom she likes but doesn’t love. Perhaps she hasn’t figured herself out yet. Or, she knows exactly what she does not want in a relationship!

Where we are in our lives and how we feel are a result of how deeply we’ve reflected and whether we have been honest – about who we are, what we want and what we can live with.

Being single is not a trouble-free journey, but the discerning woman knows that even if she is in a relationship, she is not exempt from feelings of isolation. So she relishes her independence even more.

Sure, the single woman can survive very well on her own. But what would she do for intimacy?

In today’s more liberal world, some “sign on” with friends with benefits, or adopt Woody Allen’s approach of, “I’m such a good lover because I practise a lot on my own.” The alternative is abstinence.

A thirtysomething single girlfriend who signed on with a friend with benefits reveals that their “relationship” is purely physical and confined to the bed; they never meet up or spend time together anywhere else.

Well, if that works for you, by all means. But if it doesn’t, heed what a wise woman once said: “You can never always have great sex, but you can always find a great massage.”

* Sandra has lost count of the men who lost her at hello, but she’s keeping an open heart and mind – even though she’s secretly infatuated with Joel Stein.

Oprah's poem about men


Oprah wrote this about men...

If a man wants you, nothing can keep him away.
If he doesn't want you, nothing can make him stay.

Stop making excuses for a man and his behavior.
Allow your intuition (or spirit) to save you from heartache.
Stop trying to change yourself for a relationship that's not meant to be.
Slower is better.
Never live your life for a man before you find what makes you truly happy.
If a relationship ends because the man was not treating you as you deserve then heck no, you can't "be friends".
A friend wouldn't mistreat a friend. Don't settle.
If you feel like he is stringing you along, then he probably is.
Don't stay because you think, "it will get better."
You'll be mad at yourself a year later for staying when things are not better.
The only person you can control in a relationship is you.
Avoid men who've got a bunch of children by a bunch of different women.
He didn't marry them when he got them pregnant, why would he treat you any differently?
Always have your own set of friends separate from his.
Maintain boundaries in how a guy treats you.
If something bothers you, speak up.
Never let a man know everything. He will use it against you later.
You cannot change a man's behavior.
Change comes from within.
Don't EVER make him feel he is more important than you are...even if he has more education or in a better job.
Do not make him into a quasi-god.
He is a man, nothing more nothing less.
Never let a man define who you are.
Never borrow someone else's man.
If he cheated with you, he'll cheat on you.
A man will only treat you the way you ALLOW him to treat you.
All men are NOT dogs.
You should not be the one doing all the bending...compromise is a two way street.
You need time to heal between relationships...there is nothing cute about baggage...
Deal with your issues before pursuing a new relationship.
"You should never look for someone to COMPLETE you... a relationship consists of two WHOLE individuals...
look for someone complimentary...not supplementary. "
Dating is fun... even if he doesn't turn out to be Mr. Right.
Make him miss you sometimes...when a man always knows where you are, and you're always readily available to him
- he takes it for granted.
Never move into his mother's house.
Never co-sign for a man.
Don't fully commit to a man who doesn't give you everything that you need.
Keep him in your radar but get to know others.
