Success of tsunami forecast depends on identifying the true cause of an earth quake. If the earth's crust moved horizontally during plate movement during an earthquake rather than vertically, it won't trigger tsunami. Vertical tectonic plate movement displaces water upwards, it can trigger massive columns of waves — as was the case in 2004 - and cause tsunamis.
As a result, the speed at which scientists can identify the direction in which the earth's crust has moved in the event of an earthquake is crucial in issuing an accurate tsunami forecast quickly.
It illustrates the concepts of accretion — when the tiny droplets of water that form clouds bump into each other and combine to form larger drops — and cohesion, the attraction that water molecules have for each other. The “saturation point” that is mentioned in the video is the point at which a cloud can no longer absorb any more water and may release it as rain.
I am disappointed by this assertion : “I’m nonetheless going out on a limb and guessing that science will never, ever answer what I call “The Question”: Why is there something rather than nothing?” End of the science? Really? So it’s okay to chuck 2,000 years of scientific method out the window – a method that does not claim it will always find the truth, but a method that at least doggedly pursues the possibility that one *can* find answers rather than shrugging and assuming that not everything can be understood.
What a gloomy picture?! Negative vibes? Yes. Science is still in its infancy. We cannot expect much from a child. It still has to grow a lot, learn a lot, think a lot, experiment a lot and come up with explanations.Is it even right to expect a child to solve all your problems and answer all your questions? Is it right to explain things in the way religion or baseless beliefs do about the existence of our universe? If God, if one really exists, came into existence on his/her own from nothing, like the believers say, the universe could also have originated out of nothing without anybody or anything creating it! How is that for an explanation?! Some Eastern religions say God is present in each and every atom of this universe and universe itself is the image of God and you cannot separate God from the universe! This fundamental question of origins of universe or God is too complex for an infant science to answer. Science has imbibed positiveness in me and I hope the difficult questions will be answered by science one day not in the immediate future though or in our life times.Have patience. Let science and human understanding grow to an adult stage. And be positive.
What is sixth extinction?: An exhaustive survey of the 5,487 identified species of mammals—which includes us—reveals that one in four are dying out. From amphibians to corals, the planet’s animals are disappearing, mowed under by increasing cropland, felled forests and polluted oceans. This disappearance of plants and animals from our planet has been dubbed the sixth extinction because it may be the sixth time that the Earth has experienced a mass loss of species.
Why there are less women in science and technology areas: Science and technology doesn't discriminate between men and women. According to Ms. Tessy Thomas, India's missile woman, Science has no gender. Science does not know from where knowledge is coming - it is only the willingness to learn and know things that matters. If you are willing to take on challenges and learn from experience, that is what is required for women to shine in science and technology. When women do excel in male-dominated jobs, they're not generally celebrated for it. In fact, women may be penalized for being too ambitious, too confident, too assertive.
People attribute 'hard work' to men and 'household' work to women. The requirements for doing well in certain scientific fields don't fit with the attributes women are considered to have.
This stereotype is not correct and is responsible for the backwardness of women.
FOURTH INTERNATIONAL CONFERENCE ON SCIENCE IN SOCIETY University of California, Berkeley, USA
17 - 19 November 2012
This Conference will address disciplinary and interdisciplinary challenges in the sciences, and in particular the relationships of science to society. http://science-society.com/conference-2012/
Science can be neither conquered nor defended by armies and its advancement will change the way humans govern themselves. Science cannot be controlled or arrested. Science doesn't respect distances or frontiers or laws. The major thing is the world is becoming ungovernable. The real force in our time is no longer politics, but science. And science took away the strengths of politics. Citizens now must be persuaded rather than ordered in this new age of knowledge - Israeli President Shimon Peres
How does art inspire science? It may seem a difficult question to answer with any empirical evidence, but in a new research project Scottish scientists aim to do just that.
Launched yesterday, What Scientists Read? will aim to find out what influence literature has on scientists and the decisions they make.
Asking questions like “how does reading literature affect scientific thought and practice?” and “does reading literature affect the career decision to become a scientist?”, the project team will conduct interviews with scientists in Scotland to try to unravel the influence on science of the creative arts.
Fear not, though. Even if you’re ruled out of the interviews due to geographical disadvantages you can still take part in the study. The project’s website hosts a forum where any scientist can go and add to the discussion.
The launch of the project is great timing. At the crossroads between science and art there has long been debate about how the arts feed back into scientific research - whether as a justification for the art or for the funding - but for ArtLab nothing is going to be as compelling as some cold, hard scientific fact.
Heatstroke can certainly be a factor, as can hyponatremia -- low sodium levels in the blood often caused by drinking too much water during exercise. However, in the vast majority of cases, people die during marathons because of a heart attack. Marathon running puts an extraordinary stress on your heart, one that your body was not designed for.
It's a classic example of a concept known as "the reverse effect" – where too much of something that is normally good for you can have the opposite impact. According to a study presented at the Canadian Cardiovascular Congress 2010 in Montreal, regular exercise reduces cardiovascular risk by a factor of two or three.
Research by Dr. Arthur Siegel, director of Internal Medicine at Harvard's McLean Hospital, also found that long-distance running leads to high levels of inflammation that may trigger cardiac events,iii and a separate study published in Circulation found that running a marathon lead to abnormalities in how blood was pumped into the heart.Research by Dr. Arthur Siegel, director of Internal Medicine at Harvard's McLean Hospital, also found that long-distance running leads to high levels of inflammation that may trigger cardiac events,iii and a separate study published in Circulation found that running a marathon lead to abnormalities in how blood was pumped into the heart.iviv

Do you have something original to say about our world that is increasingly fuzzy, unstable and chaotic? Are you interested in how crisis, uncertainty and complexity can come together in order to question the known as well as predict and/or model yet unknown? Do you want to share projects intrinsically linking domains of scientific, artistic and technological research and creativity that can be introduced as relevant tools for better understanding of our common future? We invite you to respond to the Tribute to Uncertainty theme. http://mutamorphosis.org/2012/tribute-to-uncertainty/
How Science of animal colours helping us: Birds, butterflies, squid and other creatures often sport intense or changing colors that are not formed by pigments but by highly organized nanostructures that researchers are only beginning to unravel. Orderly and disorderly geometric patterns of these nanostructures reflect only certain wavelengths of light, creating specific colors that in some cases can also shift if the structures get wet or if their dimensions change. Scientists are making synthetic materials that mimic these biological structures, which could lead to cars or dresses that change color as they move, sensors that detect impurities in drinking water, efficient optical chips for cell phones and authentication marks on credit cards that are exceedingly hard to counterfeit.

Bacterial cells in the body outnumber human cells by a factor of 10 to 1. Yet only recently have researchers begun to elucidate the beneficial roles these microbes play in fostering health. Some of these bacteria possess genes that encode for beneficial compounds that the body cannot make on its own. Other bacteria seem to train the body not to overreact to outside threats. Advances in computing and gene sequencing are allowing investigators to create a detailed catalogue of all the bacterial genes that make up this so-called microbiome. Unfortunately, the inadvertent destruction of beneficial microbes by the use of antibiotics, among other things, may be leading to an increase in autoimmune disorders and obesity.
Magicians use such sensory illusions in their tricks, but they also heavily use cognitive illusions, manipulating people’s attention, trains of logic and even memory. Although magicians probably haven’t studied these phenomena with the scientific method—they don’t do controlled experiments—their techniques have been tested over time, perfected by practice and performed under conditions of high scrutiny by skeptical audiences looking to spot the trick.
Magic tricks often work by covert misdirection, drawing the spectator’s attention away from the secret “method” that makes a trick work.
Neuroscientists are scrutinizing magic tricks to learn how they can be put to work in experimental studies that probe aspects of consciousness not necessarily grounded in current sensory reality.
Brain imaging shows that some regions are particularly active during certain kinds of magic tricks
Most scientists agree that sleep has significant benefits for learning and memory.
Conventional wisdom holds that recently formed memories are replayed during sleep and in the process become more sharply etched in the brain.
Emerging evidence suggests that sleep also serves as a reset button, loosening neural connections throughout the brain to put this organ back in a state in which learning can take place.
Innovation matters in an enormous variety of professions. It elevates the careers of chefs, university presidents, psychotherapists, police detectives, journalists, teachers, engineers, architects, attorneys and surgeons, among other professionals.
Although creativity was long considered a gift of a select minority, psychologists have now revealed its seeds in mental processes, such as decision making, language and memory, that all of us possess.
Techniques for boosting creative potential may involve breaking down established ways of viewing the world or invoking unconscious thought processes.
