Astronomers discover five-planet system orbiting star
Astronomers have said they have discovered a fifth planet orbiting a sun-like star 41 light years away, making it the first planetary quintet outside our solar system.
The newfound planet joins four others circling the nearby star 55 Cancri in the constellation Cancer.
Although it resides in the star's so-called habitable zone, a place where liquid water and mild temperatures should exist, it is more like Saturn than Earth and therefore not likely to support life.
Still, scientists have not ruled out the possibility of finding an Earth-like planet within this system as technology improves.
The other planets in the 55 Cancri system were discovered between 1996 and 2004.
The innermost planet is believed to resemble Neptune while the most distant is thought to be Jupiter-like.
Scientists have detected some 250 exoplanets, or planets orbiting a star other than the sun.
The 55 Cancri star holds the record for number of confirmed planets.
Only one other star is known to have four planets, while several others have three or less.

Route Dispersal Guidelines (RDG) in Airlines
* These guidelines stipulate that a minimum number of flights should be deployed on loss making routes.
* The Airlines have been demanding that a fund, termed the Essential Air Services Fund, may be created levying a cess on both the domestic and international passengers. The Civil Aviation Ministry will utilize the fund to provide to subsidy to airlines flying to identified uneconomic routes.
* But this is surely going to impose an additional burden on the consumer. This needs some explanation. The RDG make it mandatory to the company to fly to uneconomic routes. The expenditure/loss relating to such operations cannot be transferred by the Airline directly to the other passengers. It is only the combined performance of the company that will matter. Now, the creation of a fund, will make it easy for the companies to charge additional amounts from the customers.

NASA discovers magnetic ropes which connect Earth to the Sun
A fleet of NASA spacecraft has discovered the existence of giant magnetic ropes (a twisted bundle of magnetic fields), that connects Earth's upper atmosphere directly to the sun, among other findings.
The discovery was a result of the analysis of the spectacular eruptions of Northern Lights called "substorms" and the source of their power.
The magnetopause is where the solar wind and Earth's magnetic field meet and push against one another. There, the rope formed and unraveled in just a few minutes, providing a brief but significant conduit for solar wind energy.
Among other findings, the mission known as THEMIS (Time History of Events and Macroscale Interactions during Substorms) observed the dynamics of a rapidly developing substorm, and witnessed small explosions in the outskirts of Earth's magnetic field.

World's largest and deadliest spitting cobra identified
Researchers have identified the world's largest and most deadliest known species of spitting cobra.
Named as Ashe's spitting cobra, or large brown spitting cobra, this reptile can reach lengths of more than 9 feet (274 centimeters) and is believed to deliver more venom with a single bite than any other cobra on the planet.
Known to exist in the dry lowlands of north and east Kenya, as well as in Uganda and Ethiopia, the snake was previously identified as a brown-colored variant of the black-necked spitting cobra.
other variants of the black-necked spitting cobra fought harder when handled and took longer to settle down in captivity. Also, once these snakes were placed in cages, they became picky eaters.
But the 'Ashe's cobra' was less resistant to handling, generally less alert, less picky and were much bigger than the black necked spitting cobra.
The new finding might prove to be of significance for residents along Kenya's Indian Ocean coast, who are at risk of being bitten by the new cobra.
Though the venom of the new species of the cobra is similar to the species it was previously grouped with, it can deliver about twice the amount of venom with a single bite.

what is the difference between solar thermal and solar photovoltoics?
o Solar thermal energy is a technology for harnessing solar energy for heat. This is very different from solar photovoltaics, which convert solar energy directly into electricity.
o Polysilicon is the essential raw material in the production of solar cells. This material is very costly right now. About 10 tonnes of this material is required to produce 1 MW of solar energy.

Budget 2008: New grad scholarships aim to attract international talent
Will help universities compete globally for talent
The Harper government launched a prestigious scholarship program in the 2008 Budget aimed at attracting bright, young graduate students to Canadian universities.
The program will award 500 PhD students with $50,000 each year for up to three years of study. The program will cost the government $25-million over two years. It will be open to both Canadian and international students.
The new initiative is a response to universities’ complaints that they are unable to attract the world’s brightest students to Canada. The program, named after Governor General George Vanier, aims to compete with high profile scholarship programs like the Rhodes program.
Many university officials applauded the act. According to Ronald Bordessa, president of the University of Ontario Institute of Technology, the new Vanier scholarships are a step in the right direction. The budget “will help recruit top quality graduate students including international students.” According to Bordessa, this is a step in the right direction that will make Canadian universities more competitive, and help to both keep talent and attract talent to Canada.
But not everyone agrees that the move hits the mark. James Turk, executive director of the Canadian Association of University Teachers, pointed out that the program is only going to help 500 students. ““Our general reaction is that it is a budget with no understanding of the needs of PSE,” he said, arguing that there was a lack of announcements that would help the other 600,000 students or institutions themselves.

New species of pig-like animal discovered
Scientists have discovered a new species of a pig-like mammal called a peccary in the southeastern Amazon region of Brazil.
Given the name Pecari Maximus, this new animal was found in the basin of the Rio Aripuan. It was confirmed to be a distinct species via a genetic analysis conducted by the Leiden Centre for Environmental Sciences in the Netherlands. Peccaries are hoofed animals closely related to swine and hippopotami. Until now, only three species were known to science - the collared peccary, the white-lipped peccary and the Chaccoan peccary.Though Pecari Maximus is new to science, locals already knew about the creature. Tupi Indians called it Caitetu Munde, which means 'great peccary which lives in pairs.'

NASA scientists discover heftiest known Black Hole
Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star.The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star.
The newly discovered object belongs to the category of "stellar-mass" black holes.
Formed in the death throes of massive stars, they are smaller than the monster black holes found in galactic cores.
The previous record holder for largest stellar-mass black hole is a 16-solar-mass black hole in the galaxy M33.
The black hole is located in the nearby dwarf galaxy IC 10, 1.8 million light-years from Earth in the constellation Cassiopeia.

PRECISION FARMING
Precision farming, sometimes called site-specific farming, is an emerging technology that allows farmers to adjust for within-field variability in characteristics like soil fertility and weed populations.
Precision farming uses the global positioning system (GPS), consisting of 24 satellites that transmit signals picked up by user receivers to define the receiver's location. With this information and on-board sensors, farm equipment can monitor crop yields and guide applications of crop inputs like fertilizers and herbicides.
Precision farming has the potential to reduce costs through more efficient and effective applications of crop inputs. It can also reduce environmental impacts by allowing farmers to apply inputs only where they are needed at the appropriate rate.

How we hear whispers
MIT researchers have shed more light on the current understanding of the inner ear function, by discovering a small mechanism inside the organ that helps us hear whispers.
The tectorial membrane, a gelatinous structure inside the cochlea of the ear, is much more important to hearing than previously thought.
The cochlea, is a part of the inner ear where physical sound is translated into electrical signals for the brain.Inside this coiled tube, sound waves glide along a thin membrane, known as the basilar membrane, causing hair-like fibers on the membrane to vibrate at different frequencies. Once stimulated, the fibers emit electrical pulses that the brain uses to determine the pitch of the sound.Hovering right above all of this is the tectorial membrane, along which a different kind of sound wave travels.This wave, which bounces from side to side, can stimulate the hair cells and also enhance their sensitivity, which Ghaffari said might help elucidate how we can pick up on sounds that are as quiet as a whisper.

osmotic power plant
* It is interesting to know how power is produced through this process.
* Sea water and fresh water are separated by a membrane. The sea water draws fresh water through the membrane. This results in increased pressure on the sea water side. The increased pressure is used to produce power with a turbine.

When did oxygen appear on Earth?
* Recent research suggests that Oxygen would have appeared on Earth for the first time about 50 to 100 mn years before the Great Oxidation Event. The latter is believed to have occurred about 2.3 to 2.4 bn years ago. Today oxygen makes up about 21% of the atmosphere. Before the Great Oxidation Event occurred it was methane and ammonia which composed the atmosphere on the Earth.
Cold fusion
* There are two methods in which nuclear energy can be produced. One is the nuclear fission. The other is nuclear fusion. The latter one is usually the thermo nuclear fusion that is widely known. But there is a third method called cold fusion.
* When deuterium atoms are inserted inside a metal such as palladium, titanium, nickel, etc., in sufficiently large numbers and if the right Nuclear Active Environment is created, a variety of nuclear reactions are found to occur involving not only the deuterium nuclei but also the host metal atoms. In this process, excess energy is often found to be produced and in some cases nuclear particles such as neutrons, X-rays or even charged particles are released. This is called cold fusion.

The Compact Disk or CD is 25 years old
It was on August 7,1982, that the world’s first music CD rolled off the assembly line in a factory near Hannover in Germany, owned by Philips, the Dutch company that co-developed the new recording technology with Japan-based Sony.The technology of the music CD was soon modified to create the CD-ROM (for read only memory) which quickly became the de facto recording and portable storage medium for the personal computer. The total sale of CDs now exceed 200 billion; but after the turn of the century, CDs which could hold about 650 megabytes of data or 70 minutes of video, saw a drop in demand as buyers moved to the Digital Versatile Disk or DVD with an almost seven-fold increase in capacity.Interestingly, the world’s second largest maker of optical storage devices such as CDs and DVDs is an Indian undertaking — Moser Baer — which rolls out over 3.2 billion disks a year from its plant in Noida near Delhi.The company has already moved to the next era of the high density DVD which kicks up the storage capacity of each platter to over 25 gigabytes. It is operating internationally certified production processes for both competing high density DVD standards — HD DVD and Blu ray.
Blu-Ray disc
* It has a storage capacity of 5 to 10 times over a DVD. Its storage capacity comes in terms of layers. A double-layer Blu-Ray disc can store up to 50 GB. Its capacity goes on increasing with addition of layers.
