Image for the Day… Spacewalk Selfie …!!!

Astronaut photograph reflected in space helmet visor during spacewalk

Expedition 45 Commander Scott Kelly took this photograph during a spacewalk on Oct. 28, 2015. Sharing the image on social media, Kelly wrote, “#SpaceWalkSelfie Back on the grid! Great first spacewalk yesterday. Now on to the next one next week. #YearInSpace”

This was the first spacewalk for both Kelly and Flight Engineer Kjell Lindgren; the two will venture outside the International Space Station for the second time on Friday, Nov. 6. The two spacewalks were scheduled around milestones in space. Today, Oct. 29, Kelly becomes the U.S. astronaut who has lived in space the longest during a single U.S. spaceflight, and on Monday, Nov. 2, the crew celebrates the 15th year of a continuous human presence in space aboard the station.

During the 7-hour and 16-minute spacewalk, Kelly and Lindgren applied a thermal cover on the Alpha Magnetic Spectrometer; applied grease to a number of components in one of the latching ends of the Canadarm2 robotic arm; and began work to rig power and data system cables for the future installation of a docking port to the station that will be used for the arrival of the Boeing Starliner CST-100 and SpaceX Crew Dragon spacecraft.

Here’s one of our favorite photos from an EarthSky community member, so far this year. Jeff Berkes captured it during the recent total eclipse of the moon – September 27, 2015 – and the photo shows the eclipsed moon next to an eruption of Old Faithful geyser in Yellowstone National Park in Wyoming. Jeff wrote:

Over a year of planning paid off!

Old Faithful, the super Blood Moon fully eclipsed, a meteor, the Andromeda galaxy and the Milky Way… There is a lot going on in this shot!

See the Andromeda galaxy? It’s at about 10 o’clock, above the geyser. The meteor is directly above the geyser.

10 Strange Things That You Probably Didn’t Know About The Moon….

There are few things more satisfying than looking up into the sky on a clear night and seeing the moon. Whether it’s bright and full or partially hidden in shadow, there’s something cool about watching the moon pass through its many phases. We start learning about our moon and how it works at an early age, so we must know it all by now, right?

Well, maybe not. Here are a few facts about the moon that you probably weren’t taught in school.

1. It might be Earth’s twin.

It might be Earth's twin.

Some people consider our moon to be the Earth’s twin! Due to it’s large size and strange orbit, there are a few people out there who actually think of our moon as its own planet.

2. It’s been used as a burial ground.

It's been used as a burial ground.

While this person technically isn’t buried on the moon, the ashes of former NASA scientist Eugene Shoemaker were scattered across the moon’s surface. It was his dying wish.

3. It might have been inhabited once.

It might have been inhabited once.

Some photos of the moon’s surface show things that NASA can’t explain. Some believe that these phenomena are evidence of previous inhabitation. Since the photos are so grainy and obscured, however, it’s hard to tell exactly what the images are showing. Did an advanced race live on the moon long before humans started poking around up there? We may never know.

4. Shadows are darker on the moon.

Shadows are darker on the moon.

When astronauts first started visiting the moon, they noticed that their shadows were much darker than usual. This causes numerous problems for researchers to this day, since these dark shadows sometimes make it hard for astronauts to see what they’re doing up there. It’s hard to avoid stepping into a crater when your shadow is too dark and dense to see through.

5. Moon dust can cause breathing problems.

Moon dust can cause breathing problems.

The moon’s chalky debris is so fine that it has been known to move right through astronauts’ helmets and into their noses and mouths.

6. Playing in the moon’s low level of gravity isn’t as fun as it seems.

Playing in the moon's low level of gravity isn't as fun as it seems.

It may seem like fun to jump around in low gravity, but it has actually caused a ton of problems for astronauts, especially back in the early days of space exploration. Back then, their suits were so heavy that they were forced to move painfully slowly using kangaroo-like leaps.

7. We have earthquakes down here, and the moon has moonquakes up there.

We have earthquakes down here, and the moon has moonquakes up there.

If you thought that the Earth was the only planet to experience tremors, you’re wrong. The moon, which isn’t even a planet, has moonquakes that can reach a magnitude of 5.5 on the Richter scale.

8. People litter on the moon, too.

People litter on the moon, too.

On the moon, there is an alarmingly large amount of trash left over from experiments. Some astronauts have even left their poo bags up there.

9. Some people believe that the moon’s phases affect sleep patterns.

Some people believe that the moon's phases affect sleep patterns.

It is believed that the moon actually affects how humans sleep. Different phases of the moon’s cycle cause us to rest better or worse than others.

10. Researchers still don’t really know how the moon came to be.

Researchers still don't really know how the moon came to be.

Scientists actually don’t have any solid ideas about where the moon came from. There are a few guesses, but its origins remain a mystery.

(via Listverse)

That’s fascinating, isn’t it? All of these cool facts kind of make me want to become an astronaut. Okay, that won’t happen, but if any of you end up going to the moon, look into these mysteries!

” I Knew Crows Were Clever…But I Had No Idea That They Were This Smart…” !!!

Most people don’t know this, but crows are actually some of the most intelligent animals on Earth. And there are scientific studies to back up that claim. Take this experiment, for example. One study based on Archimedes’ principle determined that crows actually have a better understanding of how water displacement works than children do.

As you’ll see in the incredible video below, a clever crow figured out that it could use rocks to raise the water level enough to grab a nice drink.

This is just further proof that you should never underestimate our furry and feathered friends. Honestly, this crow has better problem-solving skills than most people in their twenties.

Message for the Day…Woman ‘Lakshmi of the Home ‘ often Lead Men on the Godward Path and the Practice of Holy Virtues …”

Sathya Sai Baba

Heaping respect and honour upon a person who does not followAtmic dharma (righteousness driven by the Self) is like heaping decorations on a body that has no life in it. The soul that left the body cannot enjoy the respect shown to the corpse. So too is the case with the person who is unaware of the Reality and the purpose of life but is crowned with fame and glory. A modest woman will not care for such meaningless trash and tinsel. This characteristic is what confers on her the title ‘The Lakshmi of the home’. The woman is the prop of the home as well as of the practice of religion. She plants and fosters religious faith. Women have natural aptitude for faith and spiritual endeavour. Women with devotion, faith, and humility often lead men on the Godward path and the practice of holy virtues.

Thought for the Day….Bright Side of Our Life….

We all know that life is too short to squander on negativity. And yet, most of us find the time for it anyway! Sure, life is challenging and often unfair, but it makes up for it in a thousand myriad little ways, you just have to notice them…

The story behind this picture of a lion getting a CAT scan….!!!

Samson the lion

The Koret School of Veterinary Medicine                                                   Samson the lion.

Earlier this year, I came across a striking image of a lion undergoing a Computerised Axial Tomography scan (or CAT scan).

I tweeted out the image, and it got over 2,000 retweets.

People were intrigued, and so was I, so I dug into the back-story of how the lion ended up there.

The photo, taken in 2005, depicts a then-2-year-old baby Barbary lion named Samson.

Barbary lions, also referred to as Atlas lions, are the largest lion subspecies known to populate large portions of North Africa.

Zoo keepers noticed that Samson, who lived in the Hai-Kef zoo near Tel Aviv with his sister Delilah, had suddenly stopped being able to walk.

At the time, Samson was suffering from what would later be diagnosed as a rare and life-threatening problem.

After the zoo had veterinary neurological specialist Dr. Merav Shamir from Israel’s Koret School of Veterinary Medicine examine Samson, Shamir observed that the lion “stood on his legs with difficulty.”

“When he tried to walk, he fell after a few steps,” noted Shamir. “He also had no appetite and appeared generally to be in poor condition.”

So Shamir decided to do a neurological exam, which included a thorough study of Samson’s nervous system. It was then that she diagnosed the lion as suffering from “damage to the posterior portion of his skull, which applied pressure on his cerebellum and the upper sector of the spinal cord.”

In other words, the cause of Samson’s trouble was in his skull. It had grown abnormally, putting unnecessary stress on the part of his brain which is vital to carrying out motor functions.

The images below, from a study Shamir coauthored, show a healthy lion skull (A) and an abnormal lion skull (B). The abnormal skull shows a malformation that’s very similar to the one Samson had. As you can see, the foramen magnum — the hole in the base of the skull through which the spinal cord passes — is unobstructed in image A. Image B shows an abnormal bone growth (identified with an asterisk) protruding down from the roof of the foramen magnum.

Screen Shot 2015 10 28 at 2.29.03 PM

After a CAT scan confirmed Samson’s diagnosis, Shamir’s team prepared for surgery.

“We decided to carry out this operation that had never before been performed anywhere,” Shamir told Hebrew University of Jerusalem.

The six-hour operation began after Samson was temporarily put to sleep with an anaesthetic.

According to The Telegraph, Shamir’s team shaved part of Samson’s mane and then used a drill to “remove part of the thickened skull tissue, some of which had become deeply embedded in the animal’s brain.”

“We were working in the dark really,” Shamir told The Telegraph. “It is difficult when you are not really sure of the anatomy and in this case the anatomy was abnormal.”
The impressive operation was successful. Within 10 days, Samson was reunited with his sister Delilah at the zoo and was walking without stumbling. Shamir thinks malformations like the one that caused Samson’s symptoms could be caused by a poor diet or other factors from captivity.

“Samson is walking around as a fully healthy lion, and our final worry is that the impressive mane which covered his head before the operation will return and cover any traces of our surgical work,” Shamir said.

Image of the Day… ” Dooms Day Vault…”

 

View larger. | Svalbard Global Seed Vault.

Researchers have been adding seeds to the Svalbard Global Seed Vault – or Doomsday Vault – since 2008. Now, for the first time, they’ve taken seeds out.

Earlier this month (October 19, 2015), seeds deposited in 2012 from war-torn Syria became the Svalbard Global Seed Vault’s first-ever withdrawal. The seed vault – located in Norway, sometimes called the Doomsday Vault – was built in 2008. Since then, researchers there have been storing containers of seeds from all parts of the globe in the vault, and this is the first time they’ve removed seeds.

According to the seed vault’s website, all seed samples in the vault remain the property of the gene banks that deposit them. A nonprofit organization in Syria had originally stored the seeds in the Arctic vault. The International Center for Agricultural Research in the Dry Areas – which promotes agriculture in developing countries – ran a major seed bank near Aleppo, Syria until 2012, when rebel forces took over that area.

Before the nonprofit shut down its Aleppo operation, researchers there were able to transfer thousands of seed samples from Syria. Some were stored in the Svalbard Global Seed Vault.

Now, researchers have taken 38,000 seeds back out of the vault. On October 19, the seeds were delivered to Lebanon and Morocco, where the nonprofit will continue the research started in Syria.

This was the first of what they say will be “several shipments” over the next few years.

PBSNewsHour reported on October 19, 2015:

The 138 black boxes stacked on trolley carts and transported out of the vault contained a precious resource — seeds, that researchers hope will restore some of the genetic diversity lost during the Syrian conflict.

Visit the website of the Svalbard Global Seed Vault.

By the way, earlier this year, a new documentary film about the Svalbard Global Seed Vault opened in theaters. It tracks the history and mission of the vault and its founder Cary Fowler. It’s available on iTunes and Netflix

Bottom line: The Svalbard Global Seed Vault – sometimes called the Doomsday Vault – opened in 2008 for the purpose of storing seeds. Researchers have been adding seeds to the vault since then, but this month – October, 2015 – for the first time, they withdrew seeds from Syria that had been placed there in 2012.

வேலவனின் திருவிளையாடல்….

இயற்கையிலேயே பெண்ணின் கூந்தலுக்கு மணம் உள்ளதா என்னும் பாண்டியனின் சந்தேகத்தைப் போக்கும் பாடலை ஏழைப் புலவனான தருமிக்கு அளித்து சிவபெருமான் திருவிளையாடல் நடத்தியதை அறிவோம். இதுபோல் வேலவனும் ஒரு திருவிளையாடலை நிகழ்த்தியிருக்கிறான்.

தாமிரபரணி நதி தீரத்திலுள்ள குருகூரில் பிரதிவாதி பயங்கரன் என்னும் புலவர் இருந்தார். அவர் போகுமிடம் எல்லாம் புலவர்களை வாதில் வெல்வார். அதோடு அவர்களிடமிருந்து அடிமை ஓலையையும் வாங்கி வைத்துக் கொள்வார். அப்படியொரு சமயம், திருச்செங்கோட்டில் உள்ள குணசீலன் எனும் புலவருக்கு, அவரோடு தான் வாதாட வருவது பற்றிய விவரத்தை அனுப்பிவைத்தார்.

எந்தப் போட்டியிலும் ஈடுபட விரும்பாத குணசீலன், இந்த இக்கட்டிலிருந்து விடுபட, வேலவனை வேண்டினார். இந்த இக்கட்டிலிருந்து உன்னைக் காப்பேன் என்று குணசீலனுக்கு வாக்களித்தான் வேலவன்.

மீதி வெண்பா எழுதிய வேலவன்

தொலைதூரத்திலிருந்து செங்கோட்டைப் பார்த்த பிரதிவாதி பயங்கரன், “அது என்ன மலை என்றான். உடன் வந்தவர்கள் “அதுதான் திருச்செங்கோடு. நாகாசலம், நாககிரி என்றும் அழைப்பர்” என்றனர்.

உடனே பிரதிவாதி, “சமர முகத் திருச்செங்கோடு சர்ப்ப சயிலமென அமரில் படம் விரித்தாடாததென்னை…” – என்று பாடத் தொடங்கிவிட்டு, மேலும் தொடர முடியாமல் தவித்தான். புதருக்குப் பின்னாலிலிருந்து ஒரு குரல் கேட்டது.

“அஃதாய்ந்திலையோ நமரன், குறவள்ளிபங்கன், எழுகரை நாட்டுயர்ந்த குமரன், திருமருகன் மயில் வாகனம் கொத்துமென்றே..”

– என்று வெண்பாவை நிறைவு செய்தான் புதருக்குப் பின்னால் மாடு மேய்க்கும் சிறுவனாக தோன்றிய வேலவன். அவனிடம் `நீ யார்?’ என்று கேட்டார் பிரதிவாதி பயங்கரன்.

“திருச்செங்கோட்டில் வாழும் தலைசிறந்த புலவர் குணசீலனின் கடை மாணாக்கன் நான்” என்றான் அச்சிறுவன். “படிப்பு வராததால் என்னை மாடு மேய்க்க அனுப்பிவிட்டார். என்னை மாணாக்கனாக ஏற்றுக்கொள்ள மறுத்துவிட்டார் புலவர்” என்றான்.

அவன் கூறியதைக் கேட்ட பிரதிவாதி, “உன் குருவுக்கு என் வந்தனத்தைத் தெரிவி…” என்று சொல்லிவிட்டு, வந்தவழியே திரும்பிச் சென்றுவிட்டார்.

முத்துசாமிக்கோனார் எழுதிய திருச்செங்கோட்டு மான்மியத்தில் மிக விரிவாக இத்திருவிளையாடல் பற்றி தரப்பட்டுள்ளது.

A Manipur farmer grows black rice that cures cancer….

Potshangbam Devakanta from Manipur shows the way in conserving the biodiversity of the state, farming around 100 traditional varieties of paddy and rare medicinal plants, finds Manu A B/Rediff.com.

When farmers across India are grappling with weather woes and poor yields, Devakanta from Manipur has succeeded in adopting smart and eco-friendly methods of farming to ensure the harvest is satisfactory year after year.

Like thousands of farmers in India, 60-year-old Devakanta too toils in the paddy fields in Imphal for long hours.

What makes him different from other farmers is his passion to conserve a wide variety of rice in his organic farm, including cancer-curing black rice, called ‘chakhao poireiton’ and drought resistant varieties.

Image: Devakanta’s organic farm is an insiration for many farmers.

He has so far succeeded in persevering 100 traditional varieties of paddy and is cultivating 25 varieties of rice in his lush green farm.

Despite India being one of world’s biggest producers of rice, little is known about the rich variety of rice that is grown across the country.

Manipur has a treasure trove of rice varieties, which can be grown in other states, which too face vagaries of nature.

Image: Devakanta won the PPVFRA conservation award.

Devakanta, who won the PPVFRA conservation award (Protection of Plant Varieties And Farmers Rights Act) in 2012, also cultivates 5 varieties of the rare and highly nutritious variety of black rice, called ‘chakhao poireiton’.

He has travelled all over Manipur, collecting different types of rice – from drought-resistant white rice (crop which needs less water), brown rice and black rice. Manipur is famous for black rice, which has several medical properties as well.

“In Manipur, farmers grow about 20 varieties of black rice and chakhao protein is the best variety.

Image: ‘Black rice, ayurvedic medicines and organic food can lead to a complete cancer cure.’

It has a relatively high mineral content, including iron and amino acids. There are several cases where even cancer patients got cured by having this black rice,” says Devakanta.

Devakanta is currently working with about 200 farmers to increase the cultivation of chakhao poireiton in their farms as well. He inspires other Manipuri farmers to grow this rare rice.

“I am recommending chakhao poireiton to cancer patients who seek my advice. Considering the high prices of allopathic drugs which also have terrible side effects, it is advisable to have black rice. Black rice, ayurvedic medicines and organic food can lead to a complete cancer cure,” explains Dr Anjali Pathak, naturopath and organic consultant.

Image: Devakanta sells organically grown black rice from his farm for just Rs 150.

The rice is also good to fight dieases like viral fever, dengue, chikungunya or influenza.

While some e-commerce sites sell black rice for Rs 300-350 a kg, Devakanta sells organically grown black rice from his farm for just Rs 150.

“I have adopted organic methods of farming. I have also succeeded in convincing many farmers to switch to organic farming. It’s high time we stopped using harmful insecticides and fertilisers. The soil here is very fertile and it is our duty to maintain by using only natural manures and bio-agents to protect the crop,” explains Devakanta.

Image: The produce is high on nutritional value and ensures people who consume it are healthy and have a longer life span.

Many people know that he has an organic farm. So they come to him to buy different varieties of rice. However, if he gets the organic certification, he can package the rice better and sell it for a higher price.

“I don’t have the money to get an organic certification done. I don’t look at the profit aspect. I am more focused on how I farm. Now people who know me buy from my farm. Manipur is one of the few states in India where there is great awareness among people to curb the use of chemicals and fertilizers,” says Devakanta.

There are groups formed by local people who charge a penalty if anyone is found using chemical fertilisers in some districts.

“Traditional methods of farming do not give much yield. From a hectare, I get just 2-3 tonnes of rice every year. However, the produce is high on nutritional value and ensures people who consume it are healthy and have a longer life span, explains Devakanta.

Manipur is a hilly area and farming is done at different altitudes. Most villages are not connected by motorable roads.

Most of the time, Devakanta and his assistants walk for 2-3 days to reach the villages to collect plants and seeds of indigenous crops.

Image: An e-commerce site to sell his products would have helped farmers like Devankanta get good exposure.

Besides the infrastructural issues, there is threat from militant groups who can field workers. “I was once caught by militants. They demanded money. Luckily they let me go after I convinced them that I am a farmer,” says Devankanta.

Farmers like Devakanta need a proper godown to store the rice, machinery to clean and sort the rice, packaging machine machine,  computers to keep stock of the inventory, cameras to document the rice varieties and medicinal plants for the benefit of researchers, funds to train the farmers in better methods of organic farming and plant protection.

An e-commerce site to sell his products would have helped farmers like him get good exposure.

Several farmers will stop growing their unique rice varieties unless they have an incentive to grow it on a large scale. Therefore, Devakanta has turned into a small scale entrepreneur to encourage these small farmers to continue growing their indigenous rice varieties. He buys the harvested rice from the small farmers and is willing to supply it in bulk to buyers in any part of India,” says Anjali pathak.

Devakanta and many farmers like him are looking for support to sustain agriculture.

“The government is not doing enough to promote agriculture. Farmers who do organic farming should be given more incentives. Scientists too must work towards growing better varieties of paddy and other crops so that weather will not spread havoc on crop yield,” says Devakanta.

Devakanta also cultivates one of the hottest varieties of chilli called ‘Bhut jolokia’. It is grown in Assam and Nagaland as well but the Manipuri chilli is considered to be better.

Image: ‘Our nature is blessed with plants that can save us from several ailments.’

Though there is a good demand for this chilli, Devakanta needs funds to buy a sturdy drier to dry the ‘bhut jolokia’ chilis during the peak season.

Devakanta is also conserving medicinal plants of Manipur. He runs an NGO called All Manipur Medicinal and Aromatic Plant Growers’ Consortium.

“We have several high medicinal value plants, some of which are good to cure cancer. Several aromatic plants can be used as inset repellents also. It is difficult to grow and maintain medicinal plants. Our nature is blessed with plants that can save us from several ailments. It is important to protest our naturally available medicinal plans before many varieties get extinct,” says Devakanta.

“Devakanta’s major challenge is to find a place to store harvested rice and spices, dry them, clean and grade it according to the quality. With proper infrastructure in place, Devakanta can provide employment to a few locals and also bring Manipur on the organic map of India,” says Anjali Pathak.

If you want to know more about Devakanta’s initiatives, you can reach him at 09862565030 / 09774269517.
