November 25, 2016: Various brain regions that once synchronised their activity during memory tasks become smaller and lose cohesion as people age, says a study.
In the study, researchers from Princeton University in New Jersey, US, described a novel method to characterise and compare the brain dynamics of individual people.

The research showed that regardless of whether we were using memory, directing attention, or resting, the number of synchronous groups of connections within our brain was consistent.
However, between different individuals, these numbers vary dramatically.
In fact, during memory specific actions, variations between people are closely linked to age.
Younger participants have only a few large synchronous groups that link nearly the entire brain in coordinated activity, while older participants show progressively more but smaller groups of connections.

In the older group this indicates loss of cohesive brain activity — even in the absence of memory impairment, the authors noted.
“This method elegantly captures important differences between individual brains, which are often complex and difficult to describe,” said Elizabeth Davison from Princeton University.
“The resulting tools show promise for understanding how different brain characteristics are related to behaviour, health, and disease,” Davison added.
For the study, the researchers used functional magnetic resonance imaging (fMRI) to record healthy people’s brain activity during memory tasks, attention tasks, and at rest.

For each person, the fMRI data was recast as a network composed of brain regions and the connections between them.
The scientists then use this network to measure how closely different groups of connections changed together over time.
The study was published in the journal PLOS Computational Biology. (IANS)
Alzheimer is a progressive cognitive disorder that destroys memory and other important mental function
In the initial stage memory loss is mild but with the time it gets worse and also causes death
There is no current cure for this but studies show certain yoga postures and natural foods can prevent from dementia and memory loss
July 28, 2017: Today, in the modern era memory loss is growing rapidly not only in the elderly man and women but in children too. Memory loss preceded to Alzheimer’s disease.
Alzheimer is the most common form of dementia, that is used for memory loss. There are common traits at the first stage of disease memory loss is mild like, now in this lifestyle, everyone is finding their self-forgetting appointments, important works, and dates, and other things, remembering faces but not names. As a result, it further leads to forgetting conversations, and respond to their particular environment.
Alzheimer is the sixth leading cause of death in the US. And more than 10 million causes per year (India). After this disease, a patient only can survive for an average of eight years.
According to a study organized by a group of scientists, according to the age, the body changes its shape and starts working at a slow pace. Similarly, our brain also seems to change its shape and starts working in different ways, in which the person gets affected by dementia and Alzheimer’s.
Until a few years ago, this memory deficiency and illness were common among the elderly people who were over 40 but now it is happening to people of all ages.
Currently no definite treatment is possible, but scientists and doctors are researching. And also what we know today, about ninety percent of Alzheimer’s has been discovered in the only last 15 years.
But here you do not need to worry, you can give your memory a power boost at any age that also naturally. With the help of yoga and natural foods.
“While practicing yoga, you focus on your breathing and are completely aware of your postures.” said by author Neha Gothe, at the University of Illinois.
According to Kristine kaoverii Weber, founder of Subtle Yoga “yoga postures seem to affect the way of thinking and reduces anxiety, stress, and it also leads to better cognitive performance.”
A research suggests that if you have practiced yoga for a long time, then you automatically tend to use of your left forebrain. There is more “gray matter” in the left forebrain and therefore, it is a reason, why positive thinking gets affected. Yoga stimulates the left forebrain and helps one to create positive and happy thoughts which in result magnifies your memory and concentration power.
Yoga Postures Which Will Improve Your Memory & Prevent You From Alzheimer:
According to study conducted by Thomas Jefferson medical college in Philadelphia and the yoga research society, there are approximately 100 billion neurons works in brain actively and most are influenced by seretonin hormone. And yoga helps the brain release serotonin naturally.
A 50 minute yoga session performed for 7 days which includes these postures will significantly reduce the cortisol level that prevents you from Alzheimer (or prevent your brain from the pressure of anxiety and stress).
Padmasana: This Yoga posture will prevent you from alzheimer
Padmasana also known as Lotus Position: is a cross-legged sitting asana originating in meditative practices of ancient India, in which the feet are placed on the opposing thighs. It is an asana, commonly used for meditation in the Yoga.
Padahastasana: This Yoga posture will prevent you from alzheimer
Padahastasana or the Hand Under Foot pose is a ‘forward bend asana’. … Padahastasana strengthens the muscles of the limbs as well as the core and promotes good form which is why it is one of the most commonly recommended yoga postures for people who are interested in overall fitness and muscle flexibility.
Sarvangasana:This Yoga posture will prevent you from alzheimer.
Sarvangasana or shoulder stand is a yoga pose wherein the whole body is balanced on the shoulders. It is also a part of the Padma Sadhana yoga sequence.

Paschimottanasana is known as ( Seated Forward Bend Pose). Helps in Alzheimer & boost memory. Try to touch your head to your both knees as shown in above image.
Tadasana: This Yoga posture will prevent you from alzheimer
There are 5 foods that prevent Alzheimer and boost your memory too.
1. Omega- 3 fatty acids
Daily contain omega 3 s in your diet it can less 26% risk of having a brain disorder that causes Alzheimer.
Omega 3 s is a fatty acid that helps brain to stay in its original shape. For getting omega fatty acids you can add fish (salmon, herring, or White tuna), flax seeds, olive oil once a week in your diet.
2. Curry powder : Will prevent you from alzheimer
Curry is used extensively in Indian food and in some other countries too. Research shows, the incidence of Alzheimer’s is lower in these places than western nations.
A prime ingredient in Curry powder is turmeric. In turmeric, there is a chemical compound curcumin found that helps the brain to intake a high amount of oxygen that regulate the balance of blood circulation in the brain. Studies have shown that, people who consumed the highest amount of curried foods have better brain activity, and concentration power.
3. Green, leafy vegetables: can cure Alzheimer
According to new research, getting regular green, leafy vegetables like- spinach, broccoli, kale, Swiss chard can help keep dementia away. Those who ate green leafy vegetables at one or twice a day have less mental disorders and deterioration than those who ate no vegetables. Green leafy vegetables loaded with vitamin A and K those helps in higher verbal episodic memory performance.
4. Avocados can also cure alzheimer
This fruit is a green powerhouse and is loaded with monosaturated fats or the “good” kind, keeping blood sugar levels steady and it contains both vitamin A and folate. Avocados help prevent blood clots in the brain as well as help improve cognitive function, especially both memory and concentration.
5. Walnuts Boosts Memory.
The shape of the walnuts is exactly like the brain, then by eating nut, the inactivity of the brain ends and the brain can help with the formation of strong and new cells. Just munching on a few walnuts a day can improve your cognitive health.
Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups
Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops
In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS
June 25, 2017: The Islamic State group is rapidly expanding in parts of Afghanistan, advancing militarily into areas where it once had a weak presence and strengthening its forces in core regions, according to Afghan and U.S. officials.
Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups.
Attacking IS has become such a priority in the country, that disparate forces sometimes join together in the ad-hoc fight, with Afghan and U.S. forces finding themselves inadvertently supporting the enemy Taliban in battling IS.
Confusion leads to mistakes
All too often, officials say, mistakes are made due to confusion on the ground.
Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops, provincial police chief, Rahmatullah Turkistani told VOA. The supplies were meant to help Afghan forces that are countering twin attacks by IS and Taliban militants but were used instead by IS.
“It’s not getting better in Afghanistan in terms of IS,” U.S. Chief Pentagon Spokeswoman Dana White told VOA this week. “We have a problem, and we have to defeat them and we have to be focused on that problem.”
Reinforcements for the IS cause reportedly are streaming into isolated areas of the country from far and wide. There are reports of fighters from varied nationalities joining the ranks, including militants from Pakistan, India, Iran, Iraq, Syria, Russia and Central Asian neighbors.
Still, the Islamic State-Khorasan (ISK) as IS is known in Afghanistan remains a fragmented group composed of differing regional forces with different agendas in different parts of the country.
“IS-K is still conducting low-level recruiting and distribution of propaganda in various provinces across Afghanistan, but it does not have the ability or authority to conduct multiple operations across the country,” a recent Pentagon report said. But where it operates, IS is inflicting chaos and casualties and causing confusing scenarios for disparate opponents.
In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS. IS regained ground after a few days, leading to U.S. military air attacks on IS positions in conjunction with Afghan intelligence instructions and army operations.
IS fighters reportedly have fled from mountain caves of Tora Bora, where al-Qaida’s leader Osama bin Laden hid from U.S. attack in 2001.
IS fighters were also reportedly advancing in neighboring Khogyani district, displacing hundreds of families, according to district officials. It is one of several areas in Nangarhar province, near the Pakistani border, where IS has been active for over two years.
Fierce clashes in the Chaparhar district of Nangarhar last month left 21 Taliban fighters and seven IS militants dead, according to a provincial spokesman. At least three civilians who were caught in the crossfire were killed and five others wounded.
“IS has overpowered Taliban in some parts of Nangarhar because the Taliban dispatched its elite commando force called Sara Qeta (Red Brigade) to other parts of the country, including some northern provinces to contain the growing influence of IS there,” Wahid Muzhda, a Taliban expert in Kabul, told VOA.
IS has also expanded in neighboring Kunar province, where, according to provincial police chief, it has a presence in at least eight districts and runs a training base, where foreign members of IS, train new recruits.
Hundreds of miles from Nangarhar, IS is attempting to establish a persistent presence in several northern provinces where it has found a fertile ground for attracting militants and recruiting unemployed youths, mostly between the age of 13 and 20.
IS has been able to draw its members from the Pakistani Taliban fighters, former Afghan Taliban, and other militants who “believe that associating with or pledging allegiance” to IS will further their interests, according to the Pentagon report.
Hundreds of militants have joined IS ranks in northern Jouzjan and Sar-e-Pul province where local militant commanders lead IS-affiliate groups in several districts.
Qari Hekmat, an ethnic Uzbek and former Taliban militant who joined IS a year ago, claims to have up to 500 members, including around 50 Uzbek nationals who are affiliated with the Islamic Movement of Uzbekistan (IMU) — previously associated with al-Qaida and Taliban in Afghanistan.
IS and Taliban are reportedly fighting over the control of Darzab district in Jouzjan which they stormed this week from two different directions and besieged scores of government forces. The Taliban has reportedly captured the center of the district while IS militants control the city outskirts.
Afghanistan faces a continuing threat from as many as 20 insurgent and terrorist networks present or operating in the Afghanistan-Pakistan region, including IS, the Pentagon said.
“In areas where the government has limited influence and control, IS attempts to emerge and expand there,” Ateequllah Amarkhail, an analysts and former Army general in Kabul told VOA.
IS has also claimed responsibility for several recent attacks in urban areas, however, with a hit-and-hide strategy that is proving effective. And it is engaging too in more skirmishes with U.S. forces that initially were sent to the country to help Afghan forces halt the spread of Taliban.
Three American service members based in eastern Afghanistan were killed in April during operations targeting IS militants, according to the Pentagon.
“ISIS-K remains a threat to Afghan and regional security, a threat to U.S. and coalition forces, and it retains the ability to conduct high-profile attacks in urban centers,” the Pentagon said. (VOA)

Its objective is to let people explore history of clothes dating as early as 3,000 years ago
June 15, 2017: To a certain extent, a culture is defined by what is worn by its people. In a country as diverse as India, vast and varied spectrum of cultures and clothes is one of the specialties. Google’s latest virtual exhibition project now provides us the opportunity to explore and know more about it.
Google’s project ‘We Wear Culture’ is collaborating with 183 renowned cultural institutions from all around the world including India and its objective is to let people explore history of clothes dating as early as 3,000 years ago, from the ancient Silk Road to the unmatched elegance of the Indian Saree, from the courtly fashion of Versailles, to the Victorian ballgowns with intricate thread work.
According to Amit Sood, director of Google Arts and Culture,”We invite everyone to browse the exhibition on their phones or laptops and learn about the stories behind what you wear. You might be surprised to find out that your Saree, jeans or the black dress in your wardrobe have a centuries-old story. What you wear is true culture and more often than not a piece of art.”
The company also mentioned that noteworthy collections from Chhatrapati Shivaji Maharaj Vastu Sangrahalaya (CSMVS) and varied weaves from across India, from Gharchola to Patola to Temple to Ikat sarees will be included in the online project, as it intends to trace the story and importance of Indian textiles from ancient sculptures.
According to PTI reports, the world fashion exhibit also includes designs from north-eastern India including the weaves of tribes such as the Nagas, Meitis. it will showcase the traditional attire from Meghalaya called ‘Dhara’ or ‘Nara’ worn by the Khasi women as well.
As a part of the exhibit, Sewa Hansiba Museum has brought the unique colorful and rich embroidery arts, applique and mirror work from different communities such as the Ahir, Rabari, Chaudhury Patel and many others from the western part of India online.
The exhibition conducted by Salar Jung Museum brings to light the Sherwani and its journey of becoming the royal fashion statement of the Nizams from 19th century Hyderabad. Fashion and textiles enthusiasts can revisit Colonial Indian attires with Dr Bhau Daji Lad Mumbai City Museum. Over 400 online exhibitions and stories sharing a total of 50,000 photos, videos and other documents on world fashion are open to exploration as well.
