A quiet sun won't save us from global warming..

EVEN if the sun were to quieten down appreciably for the rest of this century, it would still be business as usual for global warming.

The sun goes through an 11-year solar cycle during which its luminosity varies according to the number of sunspots appearing on its face. The normal cycle has a small effect on Earth's weather. But sometimes lulls in sunspot activity can last several decades, driving down the sun's luminosity to a "grand minimum". The Maunder minimum lasted from 1645 to 1715 and may have contributed to the little ice age.

Stefan Rahmstorf and Georg Feulner of the Potsdam Institute for Climate Impact Research in Germany modelled what would happen to temperatures on Earth if a grand minimum started now and lasted until 2100. They found that while temperatures would go down by as much as 0.3 °C, global warming would push up temperatures by 3.7 to 4.5 °C - more than negating any effect of a global minimum (Geophysical Research Letters, DOI: 10.1029/2010gl042710, in press).

Gavin Schmidt, a climate modeller at NASA's Goddard Institute for Space Studies in New York, agrees. "Even if the sun does something really weird, it would still be dwarfed by what we're doing," he says.

Meteor shower

Well-placed skywatchers could see hundreds of meteors an hour on Tuesday, at the peak of the annual Leonid meteor shower.

Meteors are bits of dust or rock that collide with Earth's atmosphere. The friction heats up gas particles that produce a glowing trail. A handful of meteors can be seen each hour on any clear night, but this number can spike significantly during a meteor shower.

The Leonid shower occurs each year when the Earth passes through streams of debris ejected by the comet 55P/Tempel-Tuttle, which often leaves behind dusty trails as it passes through the inner solar system every 33 years.

Earth will cut across the first such stream around 0900 GMT on 17 November, an event that is expected to produce dozens of meteors an hour. But the spectacle will reach its peak between 2100 and 2200 GMT, as Earth passes through two debris trails left by Tempel-Tuttle in 1466 and 1533.

White Coal - A good idea !!!

Guys ! if we talk about conserving our nature, we would surely think of pollution. And if talk about pollution a word comes in our mind 'smoke'. Have you ever thought how to reduce the smoke emission from burning of fuels.....

No, but I have.. You might have been heard of 'white coal' . It's a form of fuel produced by drying chopped wood over a fire. It was used in England something about seventeenth century. It produces more heat than green wood and less than charcoal and thus prevent lead emission. White coal can also be made from Ground nut husk.

Benefits of White Coal over Non Cooking coal: - -

* White coal is cheaper than heavy furnace oil ,coal & fire wood etc
* High sulphur content of oil and coal, when burnt pollutes the environment.
* There is no sulphur in the white coal, therefore no toxic gases
* Moisture contents nil because white coal is totally dry.
* Have high burning efficiency.
* Combustion is more uniform compared to coal.
* There is no fly ash when burning briquettes.
* The Calorific Value of the Finished Briquettes is Approx 3800 to 4400
K.cal/Kg.
* We are using Ground Nut Shell as raw material for the production of white coal
which gives highest i.e. 4000 to 4200 K.cal/K.G calorific value in comparison.

So, now what you think... which is best !!!

Asteroid blast reveals holes in Earth's defences

As the US government ponders a strategy to deal with threatening asteroids, a dramatic explosion over Indonesia has underscored how blind we still are to hurtling space rocks.

On 8 October an asteroid detonated high in the atmosphere above South Sulawesi, Indonesia, releasing about as much energy as 50,000 tons of TNT, according to a NASA estimate released on Friday. That's about three times more powerful than the atomic bomb that levelled Hiroshima, making it one of the largest asteroid explosions ever observed.

However, the blast caused no damage on the ground because of the high altitude, 15 to 20 kilometres above Earth's surface, says astronomer Peter Brown of the University of Western Ontario (UWO), Canada.

Brown and Elizabeth Silber, also of UWO, estimated the explosion energy from infrasound waves that rippled halfway around the world and were recorded by an international network of instruments that listens for nuclear explosions.

The explosion was heard by witnesses in Indonesia. Video images of the sky following the event show a dust trail characteristic of an exploding asteroid.

Multiplying universes: How many is the multiverse?

HOW many universes are there? Cosmologists Andrei Linde and Vitaly Vanchurin at Stanford University in California calculate that the number dwarfs the 10500 universes postulated in string theory, and raise the provocative notion that the answer may depend on the human brain.

The idea that there is more than one universe, each with its own laws of physics, arises out of several different theories, including string theory and cosmic inflation. This concept of a "multiverse" could explain a puzzling mystery - why dark energy, the furtive force that is accelerating the expansion of space, appears improbably fine-tuned for life. With a large number of universes, there is bound to be one that has a dark energy value like ours.

Calculating the probability of observing this value - and other features of the cosmos - depends on how many universes of various kinds populate the multiverse. String theory describes 10500 universes, but that just counts different vacuum states, which are like the blank canvases upon which universes are painted. The features of each canvas determine what the overall painting will look like - such as the laws of physics in that universe - but not the details.

Thanks to the randomness of quantum mechanics, two identical vacuum states can end up as very different universes. Small quantum fluctuations in the very early universe are stretched to astronomical scales by inflation, the period of faster-than-light expansion just after the big bang. These fluctuations lay down a gravitational blueprint that eventually determines the placement of stars and galaxies across the sky. Small differences in the form of these fluctuations can produce a universe in which the Milky Way is slightly bigger, or closer to its neighbours.

So just how many of these different universes can inflation's quantum fluctuations produce? According to Linde and Vanchurin, the total is about 101010,000,000 - that's a 10 raised to a number ending with 10 million zeros . Suddenly string theory's multiverse of 10500 universes is looking rather claustrophobic.

It might be, however, that this number is irrelevant, and that in a world ruled by quantum physics what matters is how many universes a single observer can distinguish. "Before quantum mechanics," says Linde, "we thought that 'reality' was a well-defined word." In classical physics, observers are irrelevant - we simply want to know how many universes exist.

First black hole for light created on Earth

An electromagnetic "black hole" that sucks in surrounding light has been built for the first time.

The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity.

A theoretical design for a table-top black hole to trap light was proposed in a paper published earlier this year by Evgenii Narimanov and Alexander Kildishev of Purdue University in West Lafayette, Indiana. Their idea was to mimic the properties of a cosmological black hole, whose intense gravity bends the surrounding space-time, causing any nearby matter or radiation to follow the warped space-time and spiral inwards.

Narimanov and Kildishev reasoned that it should be possible to build a device that makes light curve inwards towards its centre in a similar way. They calculated that this could be done by a cylindrical structure consisting of a central core surrounded by a shell of concentric rings.

NASA puzzles over 'invisible' moon impact

In the final minutes of its plunge toward the moon, NASA's LCROSS spacecraft spotted the brief infrared flash of a rocket booster hitting the lunar surface just ahead of it – and it even saw heat from the crater formed by the impact. But scientists remain puzzled about why the event did not seem to generate a visible plume of debris as expected.

As hundreds of telescopes and observers watched, the highly publicised NASA mission to search for water on the moon reached its grand finale at 0431 PDT (1131 GMT) with a pair of high-speed crashes into a lunar crater named Cabeus.

During the crucial moments at NASA's Ames Research Center in Moffett Field, California, scientists and engineers with LCROSS (Lunar Crater Observation and Sensing Satellite) peered in silent concentration as successive images of the crater grew larger on their screens.

Spacecraft kamikaze smashes into moon

As hundreds of telescopes and observers watched, a NASA mission to search for water on the moon has achieved its grand finale with a pair of high-speed crashes into the lunar surface – but there was curiously little to see.

At the Ames Research Center near Palo Alto, California, scientists and engineers with the Lunar Crater Observation and Sensing Satellite (LCROSS) peered in silent concentration as successive images of the crater Cabeus grew larger on their screens. Shortly after 4:31 am Pacific time (12:31 BST) there was no telltale flash to be seen from the expected collision of a 2366-kilogram booster rocket into the permanently shadowed crater, located near the moon's south pole.

LCROSS, which was following the booster and guiding it, trained visual and infrared cameras on the impact site for 4 minutes before it too plunged into the crater. In the final seconds before signals from LCROSS were lost, mission controllers announced detection of a heat signature from the rocket impact.

According to Michael Bicay, director of science at Ames, there are at least two possible scenarios that could explain what happened. The first is that the "gain" on the cameras was not set correctly to portray the debris plume. It could be revealed later if the data were displayed differently.

Nobel Prize 2009

Physics -

The 2009 Nobel prize in physics has been awarded to some of those whose work with light laid the foundations of the modern digital age.

The first half of the prize went to Charles Kao, formerly vice-chancellor of the Chinese University of Hong Kong, who in the 1960s made it possible for the world to talk via the light inside optical fibres.

The second half was awarded to Willard Boyle and George Smith at Bell Labs in Murray Hill, New Jersey, for the invention of the charge-coupled device (CCD) image sensor chip – a crucial component in today's digital cameras.



Chemistry -

The 2009 Nobel prize in Chemistry has been awarded to some of those whose work with ribosomes laid the foundations to scientific understanding of life and has helped researchers develop antibiotics.

Ramakrishnan, Thomas Steitz and Israeli Ada Yonath were working on ribosomes.They used a method called X-ray crystallography to pinpoint the positions of the hundreds of thousands of atoms that make up the ribosomes.

Indian-born Ramakrishnan, 57, is the senior scientist and group leader at the Structural Studies Division of the MRC Laboratory of Molecular Biology in Cambridge, England. Steitz, a 69-year-old born in Milwaukee, is a professor of molecular biophysics and biochemistry at Yale University and attached to the Howard Hughes Medical Institute, both in New Haven, Connecticut. Yonath is a professor of structural biology at the Weizmann Institute of Science in Rehovot, Israel, and the ninth Israeli to win a Nobel prize.

Largest ring in solar system found around Saturn

A colossal ring of debris found around Saturn is the largest in the solar system. The new ring could be the 'smoking gun' that explains the curious two-faced appearance of Saturn's moon Iapetus, whose leading hemisphere is much darker than its trailing side.

Until now, the biggest known rings in the solar system were Saturn's E ring and faint, gossamer sheets of dust orbiting Jupiter. Saturn's E ring, a diffuse disc of icy material fed by the moon Enceladus, extends from 3 to perhaps 20 times the radius of Saturn.

The newly discovered ring spans from 128 to 207 times the radius of Saturn – or farther – and is 2.4 million kilometres thick. It was found using NASA's Spitzer Space Telescope, which revealed an infrared glow thought to come from sun-warmed dust in a tenuous ring.

The discovery was announced on Tuesday at a meeting of the American Astronomical Society's Division of Planetary Sciences in Fajardo, Puerto Rico. "This is a unique planetary ring system, because it's the largest planetary ring in the solar system," team leader Anne Verbiscer of the University of Virginia in Charlottesville told the meeting.

The source of the ring's material seems to be Saturn's far-flung moon Phoebe, which orbits the planet at an average distance of 215 times the radius of Saturn. When Phoebe is hit by wayward space rocks, the impacts could generate debris that fills the rings.

Rain of meteorites makes the moon hum

THE man in the moon is humming a tune, but thankfully the noise won't drown out sensors on future missions peeking at the lunar interior.

A steady barrage of small meteorite impacts should cause the moon to "ring", but no seismometers sent to the moon to date have been sensitive enough to hear it. So Philippe Lognonné at the Institute of Earth Physics of Paris and colleagues decided to work out how loud the ring is.

The team estimated the meteorite population in the solar neighbourhood, and calculated the likely seismic signals that would be created by a range of meteorite sizes and velocities as they strike the moon.

World's climate could cool first, warm later

Forecasts of climate change are about to go seriously out of kilter. One of the world's top climate modellers said Thursday we could be about to enter "one or even two decades during which temperatures cool.

"People will say this is global warming disappearing," he told more than 1500 of the world's top climate scientists gathering in Geneva at the UN's World Climate Conference.

"I am not one of the sceptics," insisted Mojib Latif of the Leibniz Institute of Marine Sciences at Kiel University, Germany. "However, we have to ask the nasty questions ourselves or other people will do it."

Few climate scientists go as far as Latif, an author for the Intergovernmental Panel on Climate Change. But more and more agree that the short-term prognosis for climate change is much less certain than once thought.

Latif predicted that in the next few years a natural cooling trend would dominate over warming caused by humans. The cooling would be down to cyclical changes to ocean currents and temperatures in the North Atlantic, a feature known as the North Atlantic Oscillation (NAO).

Breaking with climate-change orthodoxy, he said NAO cycles were probably responsible for some of the strong global warming seen in the past three decades. "But how much? The jury is still out," he told the conference. The NAO is now moving into a colder phase.

Latif said NAO cycles also explained the recent recovery of the Sahel region of Africa from the droughts of the 1970s and 1980s. James Murphy, head of climate prediction at the Met Office, agreed and linked the NAO to Indian monsoons, Atlantic hurricanes and sea ice in the Arctic. "The oceans are key to decadal natural variability," he said.

Another favourite climate nostrum was upturned when Pope warned that the dramatic Arctic ice loss in recent summers was partly a product of natural cycles rather than global warming. Preliminary reports suggest there has been much less melting this year than in 2007 or 2008.

In candid mood, climate scientists avoided blaming nature for their faltering predictions, however. "Model biases are also still a serious problem. We have a long way to go to get them right. They are hurting our forecasts," said Tim Stockdale of the European Centre for Medium-Range Weather Forecasts in Reading, UK.

The world may badly want reliable forecasts of future climate. But such predictions are proving as elusive as the perfect weather forecast.

Mysterious space

Warmer seas mean more food for fish

The sheer diversity of ocean food webs has made experts fear it would be impossible to predict how climate change will affect marine ecology. But Mary O'Connor and colleagues at the University of North Carolina, Chapel Hill, may have solved the problem. They have found that plankton, the basis of marine food webs, might react predictably to ocean warming.

The team warmed 4-litre "microcosms" of seawater. They found that phytoplankton grew slightly faster with every degree of temperature rise. But zooplankton grew – and ate the phytoplankton – faster still. Zooplankton only retain about 10 per cent of the biomass of phytoplankton they eat, so there was a fall in biomass overall.

This might not be entirely bad news for people, says O'Connor. More zooplankton means more food for fish, though such top-heavy food webs could crash, she warns. "The effect could be translated up the food chain," she says. But if nutrients in the water are limited, "that top-heavy food web structure could be less stable, and crash all together."

Global warming could change Earth's tilt

Warming oceans could cause Earth's axis to tilt in the coming century, a new study suggests. The effect was previously thought to be negligible, but researchers now say the shift will be large enough that it should be taken into account when interpreting how the Earth wobbles.

The Earth spins on an axis that is tilted some 23.5° from the vertical. But this position is far from constant – the planet's axis is constantly shifting in response to changes in the distribution of mass around the Earth. "The Earth is like a spinning top, and if you put more mass on one side or other, the axis of rotation is going to shift slightly," says Felix Landerer of NASA's Jet Propulsion Laboratory in Pasadena, California.

The changing climate has long been known to move Earth's axis. The planet's north pole, for example, is migrating towards 79 °W – a line of longitude that runs through Toronto and Panama City – at a rate of about 10 centimetres each year as the Earth rebounds from ice sheets that once weighed down large swaths of North America, Europe, and Asia.

The influx of fresh water from shrinking ice sheets also causes the planet to pitch over. Landerer and colleagues estimate that the melting of Greenland's ice is already causing Earth's axis to tilt at an annual rate of about 2.6 centimetres – and that rate may increase significantly in the coming years.

Now, they calculate that oceans warmed by the rise in greenhouse gases can also cause the Earth to tilt – a conclusion that runs counter to older models, which suggested that ocean expansion would not create a large shift in the distribution of the Earth's mass.

Great threat to LIONs in Kenya

It has been found that Kenya is loosing 100 lions a year. According to the calculations it is estimated that Kenya would be devoid of all wildlife if such a terrible rate prevails.

These all circumstances are because of big bomb i.e. population explosion. The herbivorous animals are killed for meat and the grasslands are been used as homes for new population.

With the rapid growth of population the stage is reached that nearly within 10 years all the lions will disappear from Kenya.

Kenya's forest department has no strict action to control this. The biggest threat to lions is outside the protected areas. "This is because of increasing cases of poisoning by communities due to livestock loss through carnivore depredation. Typically, the communities use the insecticide Furadan by applying it on livestock carcasses."

Across the continent, the future looks bleak for lions. "Only drastic action on many fronts – policy change, effective law enforcement, giving rural people an economic stake in their natural heritage, and a great deal of investment – will prevent the loss of wildlife in Africa.

Thirstiness could again grab India...

India, a land of famine until half a century ago, could soon go hungry again for want of water to grow crops.

"Some areas of India are going to run out of water, with very severe economic and social consequences," says the chief author of a UN-backed study of water supplies for Asian agriculture, published this week.

Indian farmers now pump 60 per cent of their water from underground reserves beneath their land because irrigation canals are emptying the country's rivers, says Colin Chartres, head of the International Water Management Institute, a non-profit research centre based in Colombo, Sri Lanka.

But water tables are falling fast. "The situation is especially bad in southern India. They will run out of water first, because the hard rocks [there] have much less capacity to store the monsoon rains," says Chartres.

Half of all the water pumped from underground worldwide is in south Asia, he says. To keep bellies full, India will have to double the amount of food it produces for a given amount of water.

Cockroaches future is safe against climate change

Recent, research proved that cockroaches can hold there breath for about 40 minutes.
While resting they stop breathing and save the loss of water. Though they are the creatures of wet and moist land but they are adapted to live in dry places also.

They are blessed with such a strong system through which they can change their breathing pattern to control level of oxygen, carbon-dioxide and moisture. They close the spiracles through which they breathe primarily to save water. In dry environments these insects took shorter breaths than in moist conditions.

"Cockroaches lose water across their respiratory surfaces when they breathe," so taking shorter breaths in dry conditions reduces the amount of water they will lose.

The same thing doesn't necessarily apply to other insects. The butterfly pupae hold their breath to prevent oxygen damage, rather than to conserve water.

"So, finally cockroaches will do well for surviving against climate change.
