The Number 1 Way To Keep Your Brain Young

Ordinarily, older brains have to work harder to do the same job as younger brains.

The link between physical fitness, better brain function and brain activation has been shown for the first time.

Research on older Japanese men has shown that the brains of those who are fitter perform like those of much younger men.

The finding is based on how typical patterns of brain activation change with age.

The images below show the difference between young and old in brain activation on a typical memory test.

As you can see, younger adults primarily use the left side of the prefrontal cortex for the short-term memory task.

Older adults, meanwhile, tend to use the left and right side of the brain equally for the same task.

The reason is that with age the brain typically doesn’t work so well, so we need to utilise more of it to do the same task

Neuroscientists have a nick-name for this change: HAROLD.

It stands for “hemispheric asymmetry reduction in older adults”.

[I call it OBHTWH, or Older Brains Have To Work Harder. It’s possible the acronym could use a little work.]

In the study, though, neuroscientists found that older men who were fitter tended to use the left-side of their brains more, just like younger people.

On top of that, fitter seniors also had faster reaction times.

Professor Hideaki Soya, who led the study, said:

“…one possible explanation suggested by the research is that the volume and integrity of the white matter in the part of brain that links the two sides declines with age.

There is some evidence to support the theory that fitter adults are able to better maintain this white matter than less fit adults, but further study is needed to confirm this theory.”

We don’t yet know if the results would be the same for women, but it would be surprising if they weren’t.

The study was published in the journal Neuroimage (Hyodo et al., 2015).

The Earth is being discovered

Discovering Earth:

An innovative Earth-observing satellite now shows near-daily views of our home planet online.

After a long journey from its conception to its launch and orbit, the Deep Space Climate Observatory (DSCOVR) is now providing nearly daily views of our home planet online. It’s orbiting the Sun in step with Earth, beaming back the view from its L1 Lagrange point perspective about a million miles sunward.

Initially conceived as the NASA Tirana satellite in the late 1990s, and nicknamed ‘GoreSat’ for former Vice President Al Gore’s backing of the project, the mission evolved into the current DISCOVR satellite operated by NASA, the NOAA, and the U.S. Air Force.

Anyone can now access views of Earth in full illumination, reminiscent of the iconic ‘blue marble’ image shot by astronauts returning aboard Apollo 17.

Launched from Cape Canaveral atop a SpaceX Falcon 9 rocket on February 11th this year, DSCOVR follows Earth in its orbit around the Sun, circling the point between Earth and the Sun where gravity from the two points cancels out, known as the first Lagrangian point. Because the satellite can’t stay exactly on the L1 point, it orbits in what’s known as a ‘halo’ or Lissajous orbit around L1. The joint NASA/ESA mission SOHO is in a similar orbit about the L1 point. To date, the deployment of DSCOVR by SpaceX is the most distant fielded by the company’s Falcon 9 rocket.

An EPIC View

The images you see online at epic.gsfc.nasa.gov come courtesy of the Earth Polychromatic Imaging Camera (EPIC). The webpage notes the satellite’s position relative to the Sun and Earth, as well as the zenith points for both. EPIC’s field of view extends about 0.6 degrees wide and its resolution is about one arc second. In addition to monitoring weather patterns, EPIC will also peer through Earth’s atmosphere in the ultraviolet and infrared bands, monitoring everything from cloud dynamics to ozone and aerosol levels.

Earth’s Moon in its new phase occasionally ‘photobombs’ EPIC’s view, as it did earlier this summer, turning its unfamiliar far side toward the spacecraft, affording a unique and spectacular view.

“There will be a total solar eclipse on March 8-9, 2016 visible on the ground from the Southern Pacific,” says Adam Szabo, DSCOVR project scientist. “The Moon is not big enough to block sunlight for the whole disk of Earth. That is why total eclipses are only visible from a narrow region of Earth. From space, with DSCOVR, we should see the shadow of the Moon moving across the disk of Earth.”

Far beyond pretty pictures, DSCOVR is also providing essential climate science. In addition to instruments that monitor solar activity and the near-Earth space-weather environment, the National Institute of Standards and Technology Advanced Radiometer (NISTAR) will measure the total amount of the Sun’s irradiance that Earth reflects and emits, monitoring the spectrum from ultraviolet to infrared wavelengths. The overall energy budget of heat absorbed versus heat reflected back to space is a key piece of the climate change puzzle, and DSCOVR will scrutinize this balance in unprecedented detail.

“The DSCOVR mission has a 2-year required lifetime,” says Szabo. “After a very accurate launch by SpaceX, minimizing our correction burns, we have fuel for a considerably longer period of time. . . . We are hoping for at least five years.”

Secrets of Laddakh

12 Things We Bet You Dont Know : Secrets of Ladakh

Ladakh in the northern most stretch of India is a land of possibilities, nature’s extreme and religion. One thing that holds all these in one thread is the element of mystery. Over the past years, the mainstream world has significantly shown interest in this mystic land, but still have not been able to explore all of its faces. These enigmatic faces are usual to the locals (Ladakhis) and so are its secrets.

If you happen to travel to Ladakh anytime, try to hear out stories of all the below mentioned from a wise local. Well, these are some secrets of Ladakh which we, the mainstream world are completely unaware of:

1. Kung Fu Nuns of Ladakh

Kung Fu Nuns of ‪Ladakh‬ Dress up in Pyjamas and Yellow sashes.

The clichéd Kung fu image of the Asians, which we happen to tag with every chap having mongoloid features is somewhat true for the Ladakhis too. Although Kung Fu is not a part of the mainstream Ladakhi (Tibetan) culture, echoes of hee-yaas can be sometime heard across the hills. That’s right, there is one self-empowered branch of feminist Buddhism in Ladakh, Drukpa Nunnery, the disciples of which are known to practice the ancient Kung Fu at the very early hours of the morning.

Surprising fact is, these disciples are no martial art aspirants, but Buddhist nuns. Watching the Buddhist nuns, who are usually known for their peace loving nature and relentless towards any sort of violence, getting involved in an act of physical combat is certainly a rare sight in Ladakh.

2. In 1971, The War with Pakistan was Paused to Celebrate Losar

India-Pakistan 1971 war was paused to celebrate Losar

Who says military men can be no better than war junkies? I do not know about the most advanced Seals or Marines, but the men in uniform of India and Pakistan certainly proved this theory wrong. And that too at such a time when they were at their most ugly form against each other. Very few from either side of the borders know that the historic war in which their country took part four decades before, was put on a halt for some time, so that the locals, who were in the middle of such crises, can carry on with some festival in peace.

It was the 1971 war between India and Pakistan. Gunfires, grenades, continuous bombardments from the tanks were dismantling the Turtok village (in possession of Indian army) in Ladakh. Then suddenly, the then Commanding officer of that post, Colonel Chewang Rinchen got a conscious call, felt sentimental, and paused the war for some time. Reason being, Losar festival celebrations were about to start. I wonder how the other side fell for it and also stood at peace. The Losar festival continued for some days and so the ceasefire. Later on, the Colonel was awarded the Mahavir Chakra for his noble act.

3. Magnetic Hills

Magnetic Hill of Ladakh

One of its kind in the world is the Magnetic Hill. True to its name, the hill is known to defy gravity by pulling the cars towards it, just like a magnet. The mysterious hill is located on the Leh-Kargil-Srinagar national highway, at a height of 11,000 feet.

Locals of Ladakh have a superficial explanation about the hill. They believe that there was once a pathway (the highway connecting to the hill), which used to lead straight to heaven. Those who deserve heavenly pleasures are pulled right away by the hill, whereas who does not deserve are not.

However, modern minds take it as a nature’s phenomenon and believe magnetism of earth is the root cause of this attraction. Leh resides at one of the highest altitudes on Earth and receive the maximum radiation of the sun. This causes the magnetic pull, and fluctuations in the presence and absence of sun are bound to happen. That’s why, at the day time the magnetism is more intense than the night time.

4. Shrine of OP Baba

Enterance Gate to Shrine of OP Baba

Siachen is the highest and toughest battle field in the world. Since many decades, Indian army has made its presence to this inhospitable region, where mere survival itself becomes a challenge. Apart from the physical and mental agility, the thing that keeps them going is the unwavering faith towards a legendary soldier; the fellow soldiers prefer to consider him as their guardian deity. Legends has it that once a brave soldier named Om Prakash, single-handedly put a valiant fight against an enemy attack that took place at the Malaun post. In an attempt to safeguard the post, he laid down his life.

Today, soldiers posted there have a firm belief that the spirit of that martyr, commonly known as the ‘OP Baba’, protects the Siachen past against all odds, nature or enemy. Owing to this belief, they also made a sacred shrine of him, right at the basecamp of Siachen.

5. The Myth of Tso Kar Lake

Mysterious Tso Kar Lake of Ladakh

Ladakh surely has a mystic charm that shines out from every of its wonderful spots. One such spot is the Tso Kar Lake, which is one of the highest and the most beautiful high altitude lakes in India. The lake is crystal clear blue with patches of white (salt) on its shore. Such amalgamation of colors make it a popular tourist attraction. However, the lake hasn’t been like this in the past, as the locals talk about its story.

The myth goes like this, millions of years back, Tso Kar used to be gigantic. There was a devil, who started with the task of drinking the whole of the lake. After a point, when he got totally full and couldn’t hold any longer, he ended up spraying all of it on earth. Some amount of it spluttered towards Korzok, which formed Tso Moriri, while the rest of the water gave rise to Starspapukh and Regul Tso.

6. Rocks of Viagra

Rocks of Viagra

One of the most important ingredients of Viagra, ‘Shilajit’ has its best quality origins in the Himalayan hills of Ladakh. In the cities, this precious natural drug, known to improve sexual stamina and libido is sold at high prices, but in the barren lands of Ladakh, it is available for free.

Just like rubber, this antioxidant oozes out from the rocks and is found in great abundance. However, if you come across such rocks, don’t just start scraping it off from the rocks because it requires proper processing to get the desired drug.

7. Indian Army Training People to Build Homestay

Being a border disputed region, Ladakh in the extreme north of India has military presence since many decades. Indian army not only protects the Ladakhi borders, but also safeguards the interests of the local population. As a noble attempt, Indian army has taken the charge of training the locals to build comfortable homes for them.

Environmental conditions at Ladakh are highly unpredictable and hostile. Thus, for the rural population to be independent, the men in uniform have started this endeavor. They also contribute in the local economy by supplying fruits and vegetable at the time of shortage.

8. Road Across Khardungla

World's Highest Motorable Road

Many of us, especially the bikers who take Ladakh as an ultimate sojourn for off-road biking trips, would have been lucky to travel or simply know the highest motorable road (18,380 feet) in the world, Khardungla. But, how many of them know about the bridge that takes you to the other side of the pass? Hardly few. Well, here is another one for the great Indian army.

It was around the year 1982, when troops of the army started with the construction of a bridge that would run over, what was a glaciated patch of hard frozen rice, right ahead the Khardungla pass. Known as the Baily Bridge, it is located between the Dras and the Suru River at Khardungla pass and is the highest bridge in the world.

It was built to facilitate travel to the other high altitudes of Ladakh, and today it still stands strong, bearing the load of hundreds of army trucks and tourist vehicles on its shoulders. Unfortunately, 18 men lost their lives in the construction of the bridge.

9. The Tradition of The Order

The Tradition of Ladakh

Synonymous with Buddhist monasteries, Ladakh has monks in hundreds associated with these religious spots. These red clad peace loving monks are of every age. As per one compulsive tradition of Ladakh, the youngest child of a family would be bounded to join a monastery as per his sect and live life like a monk.

This practice was very much in common in the years of the past, but now it rarely happens. Although the region is not short of teens willing to voluntarily join the monasteries as per the order.

10 Blow a Conch to Call 120 Lamas for Lunch

Blow a conch to call for lunch

Monasteries located entirely on the edge of a cliff are some of the usual sights that you can have in Ladakh. One such structure is the Karsha Gompa which has a collection of 30 buildings built all on a vertical climb. All these buildings, whether the prayer halls, libraries or living quarters are places where 120 monks get their routine indulgences, and to call all of them for lunch and dinner can be quite a task, if you do not have an effective medium.

For that, the monastery makes use a conch shell. Every afternoon and evening, this conch shell is blown, and it resonates the whole of the monastery. The lamas or the Buddhist monks call it the call for food.

11. Druk White Lotus School

Druk White Lotus School

Located in the Shey region of Ladakh is a structure that can withstand the most hostile weather conditions and still stand unaffected. Known as the Druk White Lotus School, it was set up to instil rich cultural traditions in the students. Interesting fact about the property is that local building materials and techniques are used in the construction of it.

Considering various possibilities of extreme weather conditions that Ladakh faces, an environmental design has been chosen for the school. This sustainable design has also won the school an international reputation.

12. Where the Snake King Slept

One of the most significant and important monasteries in Ladakh, Likir is situated at a hilltop. Besides the religious significance, the monastery is popular for a different reason as well. Buddhists believe that the monastery was the place where the snake king Jokpo once slept. Infact, naming of the monastery itself signifies its association with the snake king. Likir is derived from the word Lukhgil, which means ‘coiled snake’. Monks believe that the sacred monastery is under the guard of the spirits of two legendary snakes-Nanda and Taksako.
