She was inspired to make such a wheelchair when she saw her friend's mother who is partially paralyzed."I call it a 'magic wheels' since it gives mobility to those who are otherwise dependent on others. I recon it gives more confidence to people." she added.

Sushila Sonar's interview
Ms. Sushila Sonar, a Gorkha resident of Arunachal from Naharlagun came up with a brilliant initiative of making low cost electric wheel chair out of  waste products for the Physically Handicapped people. The 'migic wheels' costs Rs 20,000 which is the cheapest so far available in the market.The avarage cost of the powered wheelchair in the market cost from Rs 60,000 to Rs10,00,000 Sonar said.

India launches record 20 satellites ISRO creates history

9:31 PM
Sriharikota: India successfully put into orbit its own earth observation satellite Cartosat-2 and 19 other satellites, including one belonging to the Google company Terra Bella, USA, on Wednesday morning. With this, India successfully completed yet another multiple satellite launch in a single rocket mission. Exactly at 9.26 am, the PSLV rocket standing 44.4 metres tall and weighing 320 tons tore into the morning skies with fierce orange flames at its tail.

Gathering speed every second, the rocket raced towards the heavens amid loud cheers from ISRO officials and the media at the rocket port here. At the rocket mission control room, Indian space scientists at ISRO were glued to their computer screens watching the rocket escaping the Earth’s gravitational pull.

Soon after the launch, a beaming ISRO Chairman A S Kiran Kumar said the mission was a success and that the new-generation Cartosat was in place. The rocket Polar Satellite Launch Vehicle’s (PSLV) main cargo was India's 725.5 kg Cartosat-2 series satellite for Earth observation with a design life of five years.

This satellite is similar to the earlier Cartosat-2, 2A and 2B. The other 19 satellites weighing around 560 kgs were from US, Canada, Germany and Indonesia as well as one satellite each from Chennai's Sathyabama University and College of Engineering, Pune.

The images sent by Cartosat satellite will be useful for cartographic, urban, rural, coastal land use, water distribution and other applications. According to ISRO, the 110 kg SkySat Gen2-1 belonging to Terra Bella, a Google company, is a small earth imaging satellite capable of capturing sub-metre resolution imagery and high definition video.

The Planet Lab’s Dove Satellites are also Earth imaging satellites. A total of 12 Dove satellites, each weighing 4.7 kg, were carried in this mission inside three QuadPack dispensers, ISRO said. The PSLV rocket also put into orbit the 85 kg M3MSat from Canada. The technology demonstration mission is jointly funded and managed by Defence Research and Development Canada and the Canadian Space Agency.

The other satellites launched are: 120 kg LAPSN-A3 of Indonesia, the 130 kg BIROS, from German Aerospace Centre, Germany and the 25.5 kg GHGSat-D, Canada. Just over 17 minutes into the flight the PSLV rocket ejected Cartosat at an altitude of around 515 km.

It was followed by two other Indian satellites — the 1.5 kg Sathyabamasat from Sathyabama University that would collect data on green house gases and the 1 kg Swayam satellite from College of Engineering, Pune, to provide point-to-point messaging services to the HAM radio community.

The whole mission got over in around 26 minutes. It was the first time that ISRO launched 20 satellites with one single rocket mission. In 2008, the ISRO had launched 10 satellites with the PSLV rocket.

With the success of Wednesday’s rocket mission, India has successfully launched 74 satellites for international customers.

All you want yo know about the Zika Virus and its First Vaccine

9:12 PM
About All you want yo know about the Zika Virus
Zika virus is spreading at a rapid pace everywhere. According to WHO (World Health Organisation), it is 'spreading explosively'. Global health officials are saying that the virus that's linked to birth defects in thousands of new-born babies in Brazil is spreading like wildfire towards America and could end up infecting 3 to 4 million people. While people race against time to find a vaccine for the terrible virus, here are some answers to questions you always wanted to ask about Zika virus and the current outbreak.
zika-symptoms
zika symptoms
What is Zika virus?
Zika is a disease caused by the Zika virus and spreads to people from a mosquito bite. Most newborns whose mothers have had the virus are suffering from Microcephaly - a disorder where the baby's head is much smaller and underdeveloped.

How does it spread to people?
Like mentioned before, the virus is transmitted through the bite of an infected female Aedes mosquito, the same kind that spreads dengue, chikungunya and yellow fever. Spreading explosively in the Americas right now, The Pan American Health Organization (PAHO) is saying that the mosquitoes can be found in all countries in the Americas except for Canada and continental Chile. The virus is likely to reach countries in the region when Aedes mosquitoes are found.

Zika virus is transmitted through the bite of an infected female Aedes mosquito.

What are the symptoms of Zika?
People who have Zika virus typically have a mild fever, skin rashes, conjunctivitis, constant muscle fatigue and joint pain from anywhere between two to seven days. The scariest bit, however, is the fact that as many as 80 percent of people infected never develop a symptom strong enough to suspect anything.

Can people die because of it?
Not that we know of right now. The PAHO said there is no evidence that Zika can cause deaths but there have been some serious complications reported in patients who are already suffering from a medical condition.

There's also microcephaly, and Guillain-Barre syndrome, a rare disorder in which the body's immune system attacks part of the nervous system. Scientists are studying whether there is a causal link between Zika and these two disorders.

What's the connection with microcephaly?
To tell you more in detail, microcephaly is a condition marked by an abnormally small head and brains that haven't developed properly in a newborn. Although scientists haven't really found a direct relationship between Zika and birth defects, it is strongly suspected. Brazil has reported around 3,700 cases of possible microcephaly that might be linked with Zika. Research in Brazil shows that the risk of microcephaly is the highest during the first trimester of pregnancy.

Is India at risk?
Not yet, but we'd be foolish to ignore it considering what's at stake here. Since the mosquito is found in abundance in the country, and dengue is a problem India faces every year, we fall in the most dangerous zone for Zika virus to spread.

How do you treat Zika? 
Unfortunately, there is no treatment or vaccine available for Zika. Companies and scientists are racing against time to develop a safe and effective vaccine, but it's not expected to be ready for months or years.

Can it be contained?
Efforts are being made to control the spread of the virus. Authorities are focusing on eliminating the breeding grounds of the mosquito and taking precautions against mosquito bites by using insect repellent and mosquito nets. Expecting mothers have been advised to avoid visiting Latin American and Caribbean countries where they might be exposed to Zika.

Which countries are fighting the Zika outbreak?
According to WHO, Zika has been reported in 23 countries in the Americas. While Brazil remains the most affected nation, other countries, and territories include Barbados, Bolivia, Colombia, Dominican Republic, Ecuador, El Salvador, French Guiana, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Martinique, Mexico, Nicaragua, Panama, Paraguay, Puerto Rico, Saint Martin, Suriname, Venezuela and the U.S. Virgin Islands, according to the PAHO.

India Has Developed The World's First Vaccine For Zika
Bharat Biotech, a city-based vaccines and bio-therapeutic manufacturer, on Wednesday claimed to have achieved a breakthrough in developing a vaccine to fight the dreaded mosquito-borne Zika virus, which allegedly causes serious birth defects in children.

Bharat Biotech is home to some of the most brilliant minds in the world and began work on the Zika virus a year ago, Krishna Ella, CMD Bharat Biotech, said.

"We believe we have an early mover advantage in developing the Zikavac and we are probably the first in the world to file for global patent for Zika vaccine candidates"
India Has Developed The World's First Vaccine For Zika, The Deadly Virus Terrifying The World!.
India develops First Vaccine For Zika, The Deadly Virus Terrifying The World!
"We have two candidate vaccines in development. One of them is an inactivated vaccine that has reached the stage of pre-clinical testing in animals," Ella said. Quoting a WHO report, he said Zika is now present in 23 countries and Brazil, the hardest-hit country, has reported around 3,530 cases of the devastating birth defect, called microcephaly, in 2015 that are strongly suspected to be related to Zika.

"We hope to announce the arrival of Zikavac to the world as early as possible," he said.
Zika virus is spread by mosquitoes of the Aedes genus, which can breed in a pool of water as small as a bottle cap and usually bite during the day. The mosquito-transmitted infection is related to Dengue, Yellow Fever and West Nile virus. "Considering that women of child-bearing age and pregnant women are the prime target group for Zika virus vaccine, we consider safety as the overriding factor in the development of a new vaccine for this virus.

The vaccine methods developed early on, before the devastating consequences of the epidemics in Brazil came to light, provided us a push to accelerate vaccine development," Dr Sumathy, Director, R&D, Bharat Biotech said.
Currently, the vaccine maker is focusing towards scale up and characterization of the vaccine product, Ella further said.

India launched Astrosat first space observatory, joins select group

11:19 AM
India launched its first space observatory, Astrosat, from the country’s main space centre at Sriharikota in Andhra Pradesh on Monday, becoming a member of the select group of space organisations to have a lookout in orbit after the US, Japan, Russia and Europe.

The satellite was zoomed into space by a PSLV C-30 rocket from the Satish Dhawan Space Centre at 10am. Six customer satellites, one (micro) each from Canada and Indonesia, and four nano satellites from the US also rode along.

“The mission envisages an earth-orbiting scientific satellite with payloads capable of simultaneously observing the universe in the visible, ultraviolet and x-ray regions of the electromagnetic spectrum,” said an Indian Space Research Organisation (Isro) official.

The satellite launch comes just a year after Isro’s first interplanetary mission, Mangalyaan, entered the orbit of Mars and on the day Prime Minister Narendra Modi is due to meet President Barack Obama during his US trip. The mission will also be the first time the country will launch US satellites.

organisation to do so. (ANI Photo)
The successful launch of India’s Mars orbiter last year came just days before Modi travelled to the US on his first trip after a landslide electoral victory.
The multi-wavelength mini Hubble-type space observatory, with an estimated cost of about Rs 180 crore and weighing 1,513 kg, will study distant stars, white dwarfs and pulsars. In particular, it will train its instruments at the massive black hole believed to exist at the centre of our Milky Way galaxy.

The Hubble launched by the US in 1990 is 10 times heavier than the Astrosat and is said to cost $2.5 billion. While the Hubble space telescope is still operational, India’s space observatory’s life span is five years.

Astrosat was launched into a 650km orbit carrying four X-ray payloads, one UV telescope and a charge particle monitor. Two of the payloads are in collaboration with the Canadian Space Agency and University of Leicester, UK.

The 44.4 metre-tall polar satellite launch vehicle (PSLV-XL) version is a four-stage rocket with six strap-on motors for additional thrust during the initial phase of the flight. The first and third stages are powered by solid fuel while the second and fourth stages are powered by liquid fuel which will be filled during the countdown.

The rocket with seven satellites cumulatively weighing 1,631 kg blasted off from the first launch pad of the rocket port.

This is the third time that an Indian rocket launched seven satellites in a single mission. In 2008, Isro had launched 10 satellites in one go, including India’s Cartosate-2A satellite.

Just over 22 minutes into the flight, the rocket will eject Astrosat. Soon after, six other satellites will be put into orbit and the whole mission will come to an end in just over 25 minutes.

The Indonesian 76 kg Lapan-A2 is a micro-satellite from the National Institute of Aeronautics and Space, meant for providing maritime surveillance using automatic identification system (AIS), supporting Indonesian radio amateur communities for disaster mitigation and carrying out earth surveillance using video and digital camera.

The 14 kg NLS-14 (Ev9) of Space Flight Laboratory, University of Toronto Institute for Advanced Studies, is also a maritime monitoring Canadian nano satellite using the next generation AIS.

The remaining four LEMUR nano satellites from Spire Global Inc, San Francisco, US, are non-visual remote sensing satellites, focusing primarily on global maritime intelligence through vessel tracking via AIS and high-fidelity weather forecasting using GPS radio occultation technology, the ISRO said.

Apart from Isro, four other Indian institutions - Tata Institute of Fundamental Research, Indian Institute of Astrophysics, Inter-University Centre for Astronomy and Astrophysics and Raman Research Institute - were involved in the payload development.

NASA named the Pluto's mountain chain as "Norgay Montes" after Tenzing Norgay Sherpa

11:02 AM
Sanjog Chamling for IG

Scientists at NASA have named the Pluto's mountain chain as "Norgay Montes" after Tenzing Norgay Sherpa an Indian Gorkha Sherpa mountaineer.When Indian government have failed to confer Bharat Ratna to Tenzing, NASA have bestowed him with this prestigious honor.

NASA's New Horizons historic flyby of Pluto have found icy mountains ( "Norgay Montes") when the first zoomed-in image of Pluto was released on Wednesday. They think mountains, which was often referred to as just an icy orb before,  are made of water ice, but they still aren't sure what's causing them to form.

People at home have been trying to recognize Tenzing  Sherpa's achievement by asking the Government to confer him with the Bharat Ratna which is the highest civilian award of the Republic of India. He was one of the first two individuals known to reach the summit of Mount Everest, which he accomplished with Edmund Hillary on 29 May 1953.

At the time when people have been trying to get some attention of the government regarding Sherpa's due right by placing the demand to rename Bagdogra airport after him and a request to confer Bharat Ratna to Tenzing, prestigious honor from NASA might play some role to reach the voice to the deaf ears of the concerned Indian authorities.
