LONDON: Scientists have announced plans to build a telescope that may give us clues to whether alien life exists on planets millions of miles away.

The Atlast, or Advanced Technology Large-Aperture Space Telescope, will be the most powerful telescope in the world and will be able to analyse atmospheres of planets and solar systems up to 30 light years away.

It is hoped that the telescope will give astronomers crucial insights into whether extraterrestrial life forms are able to exist in undiscovered areas of space.

To be able to analyse these planets, the telescope will have to be the largest of its kind ever to be built and up to four times bigger than the 44-feet Hubble Space Telescope.

Inside will be a mirror with a diameter of 52 feet, the largest man-made mirror ever.

Due to the size of the telescope, no rocket will be capable of transporting it up to space and instead, a team of astronaut construction workers will be ferried by Nasa's Orion rocket to assemble the telescope situated 1million miles from the earth's surface.

The details of the project will be revealed at this week's National Astronomy Meeting in Portsmouth by the president for the Royal Astronomical Society, Martin Barstow.

According to Barstow, the telescope will allow astronomers to discover around 60 new planets and provide information on the levels of oxygen and other gases that might indicate potential life.

Barstow told Sunday Times: "This telescope could see Earth-like planets around stars up to 30 light years away. There are tens of thousands of stars within that distance and we estimate that at least a few thousand of those will be similar to the sun."

He added: "Once it found a planet, the telescope would analyse its atmosphere for ozone, methane, oxygen and other gases which suggest the presence of life."

For the Atlast telescope to progress past the planning stage, it is believed a global collaboration between all of the world's space agencies will be required.

Barstow said: "Nasa will have to take the lead as it is the biggest space agency, but it is already in discussion with the European Space Agency, of which Britain is a member. We are looking at 2030 because that is how long these projects take."
ImmunizationMr. Harsh Vardhan, Union Health Minister on Saturday said that the Central Government is willing to launch an immunization campaign on encephalitis to ensure 100 percent immunization in states where children were hit by a suspected encephalitis outbreak. Harsh Vardhan, who arrived Patna on Friday night, said to reporters ‘My top priority now is to ensure 100 percent immunization for children of the encephalitis struck area.’ (Read: West Bengal litchi virus – kills eight childern, leaves six more in serious condition)
The Union Health Minister is set to visit the Muzaffarpur district of Bihar (the worst hit place by encephalitis) today to personally scrutinize the progress in the situation. In the past three-week time, the suspected Acute Encephalitis Syndrome (AES) has claimed nearly 130 lives of children in Bihar, mostly of to the Muzaffarpur region. He also said that the Chief Minister of Bihar, Mr. Jitan Ram Manjhi has requested him to launch this health initiative to check the disease. He also added that the center is also very serious to tackle this situation.
The Encephalitis disease that was restricted to the Muzaffarpur area till last week, has now spread to  many other surrounding districts namely – Sheohar, Vaishali, Sitamarhi, Samastipur, East Champaran, Gaya,   Bhagalpur and Begusarai districts. According to the doctors, the Acute Encephalitis Syndrome is a severe case of encephalitis that causes serious inflammation of the brain. Also, this infection is easily transmitted by mosquitoes causing high grade fever among children suffering from this condition.
What is encephalitis?
Encephalitis is a disease that results in inflammation of the brain. The patient’s central nervous system is affected. While the lesser symptoms include headaches and fevers, the more severe ones cause the onset of mental issues like seizures, confusion, disorientation, tremors and hallucinations. It can be caused due to bacterial or viral infections of the brain, injection of toxic substances or increased complications of an infectious disease. (Read:Disease trends in India)

How plants can produce species without sex

Plants can transfer their entire genetic material to a partner in an asexual manner, research reveals.
German scientists at the Max Planck Institute of Molecular Plant Physiology have shown for the first time that new species can be generated in an asexual manner as well.
It was generally believed that a combination of desired traits can be obtained by grafting, but there is no exchange or recombination of genetic material - so-called horizontal gene transfer - between the grafted plants.
"In our previous work, we were able to prove that, contrary to the generally accepted dogma, there is horizontal gene transfer of chloroplast genes at the contact zone between grafted plants," said lead researcher Ralph Bock.
Now we wanted to investigate if there is a transfer of genetic information between the nuclei as well, Bock added.
The researchers introduced resistance genes against two different antibiotics into nuclear genomes of the tobacco species Nicotiana tabacum and Nicotiana glauca, which usually cannot be crossed.
Afterwards, Nicotiana glauca was grafted onto Nicotiana tabacum or the other way round.
After fusion had occurred, scientists excised tissue at the contact zone and cultivated it on a growth medium containing both antibiotics, so that only cells containing both resistance genes and thus, DNA from both species, should survive.
The scientists succeeded in growing up numerous doubly resistant plantlets.
"We managed to produce allopolyploid plants (having two or more complete sets of chromosomes derived from different species) without sexual reproduction", said Sandra Stegemann, joint first author of the study.
When the scientists grew their new plants in the greenhouse, it became obvious that they combined characteristics of both progenitor species.
Also, the new plants grew remarkably faster than their parents.
"Grafting two species and selecting for horizontal genome transfer could become an interesting method for breeders who could use this approach to create new crop plants with higher yields and improved properties," researchers concluded.
