HELLO, ANYONE OUT THERE?

Jupiter’s moons key to alien life?

Europa, Callisto & Ganymede Fulfil All Conditions Needed To Sustain Life

Collection & Source: Times of India
Washington: Researchers are keen on exploring Jupiter’s icy moons, which may resemble some of the planets found orbiting stars beyond our solar system, to assess their suitability for life. 
Europa, Callisto and Jupiter’s largest moon, Ganymede, are all believed to have liquid oceans beneath their icy shells, as well as organic chemistry and possible sources of energy beyond the dim amount of sunlight that reaches their distant surfaces. 
These are all conditions that may be required for life in much more distant planetary bodies. 
We thought for quite some time these were dead icy bodies, but we have recently actually discovered a fabulous collection of very geologically active things there,” planetary scientist Athena Coustenis, with the Paris Ob
servatory in France, said. A newly proposed mission, The Jupiter Icy Moons Explorer, nicknamed JUICE, would send a spacecraft to study the three moons and their habitability. 
Mission planners selected Ganymede as an archetype of an exoplanet water world like GJ 1214b, a super-Earth discovered last year 
circling a star about 40 light-years from Earth. “We think it is the best example of a liquid environment trapped between icy layers,” JUICE science study team member Olga Prieto Ballesteros, with the Center of Astrobiology in Madrid, Spain, said. Europa poses an intriguing model to those exploring the possibility of alien life because its buried ocean is believed to be in direct contact with the moon’s silicate mantle, a source of salts and other elements. 
Europa is thought to be like exoplanets that are between water worlds and Earth-like bodies. 
The icy planetary bodies have opened the possibility to find habitats in deeper environments. We can say that these will expand the classical concept of habitability,” which previously was limited to places with liquid water on surface, Prieto Ballesteros said. ANI

Treatment of Tree



On its deathbed, neem tree gets A Healing Touch

A 60-year-old neem tree in central Delhi was saved from sure collapse by timely intervention. It will live on for over 20 years

    The operation went on for almost three hours but the doctors were happy with the outcome. Despite a massive insect infestation that had gnawed away its innards and a recent fracture, they believe the patient will make a full recovery and will probably live on for another 20-30 years. The 60-yearold Neem tree at the juncture of Lodhi Road and Bhishma Pitamah Marg has been given a new lease of life. 
    Its growth stunted as it struggled to survive Delhi’s harsh environment, and its roots suffocated by the tightening noose of concrete around its base, the tree was almost split into two as a huge branch was ripped off in a thunder squall last week. MCD asked the NDMC tree ambulance for help, which decided that an immediate “surgery” was needed to save the Neem. 
    Since it started operating in Delhi, the tree ambulance has saved a few hundred trees in the city, most of them in the NDMC areas. More than 50 trees have been operated upon, a procedure in which old and usually hollow trees are treated, packed with flexible material and 
sealed so that they may grow back. On Tuesday, 
the joint operation by NDMC and MCD started around 10.30am in which first the broken branch 
was removed and then the tree treated for its 
termite infestation. “The tree was very sick and would have eventually collapsed. First, we 
hacked out the termite infested part. The wood actually crumbled when we touched it. Once the major portion was removed manually, we hosed it with water jet to clean it completely,” said Kaushik. 
    Once rid of the pests, the inside of the trunk was washed with chloropyriphose, an insecticide. Then the cavity was painstakingly filled with foam, thermocol and cotton to provide support to the trunk. These were then secured using a wire mesh. “These materials were chosen as they provide support and sufficient flexibility to the tree. Wood will start growing back within the next 10 days, and as the trunk heals, these materials will be squeezed inward without any resistance. In earlier operations we used hard materials but realized that it did not leave the tree with any flexibility,” added Kaushik. 
    Finally, the materials were sealed with plaster of Paris and the fallen bark was pressed back into place. This was then secured using strips of hessian. The exposed part from where the branch had broken off was also sealed with PoP and then covered with an additional layer of cement to prevent water from going in. 

    Suhas Borkar, founder member of Green Circle of Delhi, who reported the case to authorities, says that it is not surprising for trees to collapse. “Pollution levels are rising, groundwater tables are falling and the trees are being allowed no space to breathe. Greening guidelines provide for adequate space of at least 6 X 6 feet has to be left around trees while cementing or tiling. Horticulture departments in all civic agencies should have tree disease and surgery units. None of these guidelines are being followed and Delhi’s trees are in poor shape.”

NDMC & MCD staff first sawed off termite infested part of the trunk and then hosed it with water. The cavity was then treated with insecticide and painstakingly filled up with foam, thermocol & cotton


Cavity was then sealed with plaster of Paris and cement, and bound with hessian strips in the end

डीएल और प्रदूषण प्रमाण पत्र ही पास रखना जरूरी

अब आपको वाहन चलाते समय सिर्फ असली ड्राइविंग लाइसेंस और गाड़ी का प्रदूषण प्रमाण पत्र ही रखना होगा। वाहन जांच के दौरान अन्य प्रमाण पत्रों की फोटो कॉपी मान्य होगी। निजी वाहन चालकों को राहत देते हुए दिल्ली यातायात पुलिस ने इस बारे में सर्कुलर जारी किया है। इससे पुलिसकर्मियों द्वारा सभी वास्तविक प्रमाण पत्र दिखाने के नाम पर उगाही पर लगाम लगेगी। दिल्ली के संयुक्त पुलिस आयुक्त (यातायात) सत्येंद्र गर्ग ने मंगलवार को सर्कुलर जारी करने के बाद मीडियाकर्मियों से बातचीत में कहा कि अक्सर वाहन चालकों की शिकायत रहती थी, कि इंश्योरेंस और आरसी (रजिस्ट्रेशन सर्टिफिकेट) की फोटो कॉपी दिखाने के बाद भी पुलिसकर्मी उन्हें परेशान करते हैं। अब निजी वाहन चालकों को इस तरह की परेशानी नहीं होगी। गर्ग ने कहा कि महिला और वरिष्ठ नागरिकों को वाहन के मूल दस्तावेज न दिखाने पर काफी परेशानी होती थी, क्योंकि मूल दस्तावेज न दिखाने पर वाहन को जब्त कर लिया जाता था। वाहन चोरी होने पर असली आरसी और इंश्योरेंस मांगा जाता है। जिससे वाहन मालिक को बीमा लाभ मिल सके। लेकिन वाहन के साथ ही असली प्रमाण पत्र चोरी होने पर उसे बीमा लाभ.  डीएल और प्रदूषण प्रमाण पत्र ही पास रखना जरूरी लेने में भी कई तरह की परेशानियां आती हैं। इन सब परेशानियों को ध्यान में रखते हुए ही यह प्रावधान किया गया है। अब निजी वाहन चालक अपने वाहन की आरसी और इंश्योरेंस की फोटो कॉपी रखेंगे। साथ ही डाइविंग लाइसेंस व प्रदूषण प्रमाण पत्र असली रहेंगे। फोटो कॉपी साफ होनी चाहिए, जो पढ़ी जा सके। फोटो कॉपी को किसी राजपत्रित अधिकारी से सत्यापित कराने की भी जरूरत नहीं है। उन्होंने बताया कि इस बारे में यातायात पुलिसकर्मियों सहित स्थानीय पुलिस के सभी वरिष्ठ अधिकारियों को अवगत करा दिया गया है। अगर किसी वाहन चालक को परेशानी होती है तो वह यातायात पुलिस की एसएमएस सेवा 56767 पर अपनी शिकायत दर्ज करा सकता है। इसके अलावा वाहन चालक दिल्ली पुलिस की हेल्पलाइन सेवा 25844444 पर भी संपर्क कर सकता है।

WEAVER BIRDS BAYA RETURN TO THE SUB-CITY


Source: City Plus (Dainik Jagran)
Ever seen the weaver bird Baya? If not go to these beautiful birds weaving nests in the vacant plot near Dwarka Court in front of Sector 10 Metro station. Environmentalists are surprised that the Baya birds have started weaving nests in the same patch of land where they did last year.
Even bird watcher and nature lover from Dwarka, Ramesh Chand, finds it surprising that when such birds are not seen even in forest areas, green areas and parks, they are seen in such a populated area near a metro station.
About the birds returning to the same land after one year, programme officer of Bombay Natural History Society, CR Naveen, said, "Bayas are birds which migrate locally. They usually return to the nesting sites of the previous year. They may or may not be the same birds that nested previously in the same area. But it is a very good sign that the land has become their favourite nesting place."
Centre manager of BNHS Sajeev TK said, "The weaver bird is one of the master architects of nature. The male birds play a major role in the site selection and making the nest. The females are invited by the males to inspect the half built nest. If they find the nest suitable they will join hands and complete the nest. Otherwise the half built nests are abandoned by the males and they try their luck with new nests. Thus the males with good nest-making skills alone will be able to breed and produce next generation. This also accounts for the large number of half built nests in a nesting site."
Senior Scientific Officer of Environment, Delhi Government  BC Sabat, said, "Baya birds coming again to the same land is a good sign in favour of environment. People should go and see them to feel their importance. Parents and schools should take their kids to that particular land to show these rare birds. Involvement of community is the only way to save them as it would create pressure on the authority to make them feel the importance of fauna in the sub-city." 
Important facts
The Baya's scientific name is Ploceus philippinus. Flocks of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. 
it is a very good sign that the land has become baya birds’ favourite nesting place.

Save Birds Save nature


Online dash to save the vanishing sparrow

Saswati Mukherjee TNN 

Source: Times of IndiaIf you have been missing the once-familiar chirping of sparrows around your house, here’s your chance to contribute to finding out why this common bird seems to have disappeared from cities across India. 
A two-month-long online survey called Citizen Sparrow was launched on Sunday, inviting responses from people on questions such as when they last sighted the bird and details about the area they live in. The survey can be taken at www.citizensparrow.in. 
“It is an elementary step to gather information. We are encouraging people to report their experience, be it a drastic drop in sparrow count or a sudden spurt. These inputs will give us valuable leads to compile pan-India data,” said Suhel Quader, evolutionary ecologist at the National Centre for Biological Sciences. 
The environment ministry-funded survey is being undertaken by the Bombay Natural History Society, with the help of 10 partner organizations such as the Indian Bird Conservation Network and Nature Conservation Foundation. The disappearance of the house sparrow — so widespread till recently that the Chinese Communist Party declared it a pest in 1958 and asked people to exterminate it — remains a great modern mystery worldwide. In the UK, sparrows are estimated to have declined from over 12 million to 6 million since the mid-70s. 
While in Europe the decline has been documented and studied, there has beenno major study in India so far. BNHS seeks to change that with its current initiative.
“The survey would give us the first baseline data about distribution of sparrows in the country. This would form the basis for futher research,” said Karthik K, project coordinator. 
The objective of involving ordinary citizens rather than experts comes with a purpose. “Almost everyone knows about sparrows. It is an attempt to reach out to people, asking them to share their stories and their understanding of these birds,” said Quader. 
Participants in the survey would be asked to mark locations on a map and give information about their sparrow sightings, including sightings from the last year and even earlier. Such information will enable a comparison of sparrows in different places, and this is expected to point to particular threats or problems. The findings are intended to feed detailed studies investigating causes of decline and potential measures for the recovery of sparrow populations. 
Asad Rahmani, director, BNHS, said, “The sparrow is an indicator of a trend. A number of other birds have also declined sharply in the past few decades. We hope the survey would provide more clues about why these birds are disappearing.” 
WHERE HAVE THEY GONE? 
Possible reasons for decline in sparrow numbers in cities 
Pesticides kill soft-bodied insects which sparrow chicks feed on. Pesticide in grains, food for adult birds, may also be contributing to decline.
Modern housing leaves no space for birds to nest Manicured lawns do not allow grass to seed. Seeds attract insects.
General decline in insect habitats like gardens 
Radiation from mobile towers could be affecting birds, although studies aren’t conclusive
