In this chapter of Why we do Yoga, I travel to a few new places to find out the reasons and ways people do yoga. Familiar faces and new encounters lead me through a slew of changes plans but graceful adjustments. Watch as one connection leads to another from Martinique all the way back to Atlanta and a few places in between. Luck and coincidence carried me through this one. Look forward to the next soon enough. Peace

A new type of material generates electrical current very efficiently from temperature differences. This allows sensors and small processors to supply themselves with energy wirelessly.
Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: If there is a temperature difference between the two ends of such a material, electrical voltage can be generated and current can start to flow. The amount of electrical energy that can be generated at a given temperature difference is measured by the so-called ZT value: The higher the ZT value of a material, the better its thermoelectric properties.
The best thermoelectrics to date were measured at ZT values of around 2.5 to 2.8. Scientists at TU Wien (Vienna) have now succeeded in developing a completely new material with a ZT value of 5 to 6. It is a thin layer of iron, vanadium, tungsten and aluminum applied to a silicon crystal.
The new material is so effective that it could be used to provide energy for sensors or even small computer processors. Instead of connecting small electrical devices to cables, they could generate their own electricity from temperature differences. The new material has now been presented in the journal Nature.
Electricity and Temperature
“A good thermoelectric material must show a strong Seebeck effect, and it has to meet two important requirements that are difficult to reconcile,” says Prof. Ernst Bauer from the Institute of Solid State Physics at TU Wien. “On the one hand, it should conduct electricity as well as possible; on the other hand, it should transport heat as poorly as possible. This is a challenge because electrical conductivity and thermal conductivity are usually closely related.”
At the Christian Doppler Laboratory for Thermoelectricity, which Ernst Bauer established at TU Wien in 2013, different thermoelectric materials for different applications have been studied over the last few years. This research has now led to the discovery of a particularly remarkable material—a combination of iron, vanadium, tungsten and aluminium.
“The atoms in this material are usually arranged in a strictly regular pattern in a so-called face-centered cubic lattice,” says Ernst Bauer. “The distance between two iron atoms is always the same, and the same is true for the other types of atoms. The whole crystal is therefore completely regular.”
However, when a thin layer of the material is applied to silicon, something amazing happens: the structure changes radically. Although the atoms still form a cubic pattern, they are now arranged in a space-centered structure, and the distribution of the different types of atoms becomes completely random. “Two iron atoms may sit next to each other, the places next to them may be occupied by vanadium or aluminum, and there is no longer any rule that dictates where the next iron atom is to be found in the crystal,” explains Bauer.
This mixture of regularity and irregularity of the atomic arrangement also changes the electronic structure, which determines how electrons move in the solid. “The electrical charge moves through the material in a special way, so that it is protected from scattering processes. The portions of charge traveling through the material are referred to as Weyl Fermions,” says Ernst Bauer. In this way, a very low electrical resistance is achieved.
Lattice vibrations, on the other hand, which transport heat from places of high temperature to places of low temperature, are inhibited by the irregularities in the crystal structure. Therefore, thermal conductivity decreases. This is important if electrical energy is to be generated permanently from a temperature difference—because if temperature differences could equilibrate very quickly and the entire material would soon have the same temperature everywhere, the thermoelectric effect would come to a standstill.
Electricity for the Internet of Things
“Of course, such a thin layer cannot generate a particularly large amount of energy, but it has the advantage of being extremely compact and adaptable,” says Ernst Bauer. “We want to use it to provide energy for sensors and small electronic applications.” The demand for such small-scale generators is growing quickly: In the “Internet of Things,” more and more devices are linked together online so that they automatically coordinate their behavior with each other. This is particularly promising for future production plants, where one machine has to react dynamically to another.
“If you need a large number of sensors in a factory, you can’t wire all of them together. It’s much smarter for the sensors to be able to generate their own power using a small thermoelectric device,” says Bauer.

Internet censorship by authoritarian governments prohibits free and open access to information for millions of people around the world. Attempts to evade such censorship have turned into a continually escalating race to keep up with ever-changing, increasingly sophisticated internet censorship. Censoring regimes have had the advantage in that race, because researchers must manually search for ways to circumvent censorship, a process that takes considerable time.
New work led by University of Maryland computer scientists could shift the balance of the censorship race. The researchers developed a tool called Geneva (short for Genetic Evasion), which automatically learns how to circumvent censorship. Tested in China, India and Kazakhstan, Geneva found dozens of ways to circumvent censorship by exploiting gaps in censors’ logic and finding bugs that the researchers say would have been virtually impossible for humans to find manually.
The researchers will introduce Geneva during a peer-reviewed talk at the Association for Computing Machinery’s 26th Conference on Computer and Communications Security in London on November 14, 2019. “With Geneva, we are, for the first time, at a major advantage in the censorship arms race,” said Dave Levin, an assistant professor of computer science at UMD and senior author of the paper. “Geneva represents the first step toward a whole new arms race in which artificial intelligence systems of censors and evaders compete with one another. Ultimately, winning this race means bringing free speech and open communication to millions of users around the world who currently don’t have them.”
All information on the internet is broken into data packets by the sender’s computer and reassembled by the receiving computer. One prevalent form of internet censorship used by authoritarian regimes works by monitoring the data packets sent during an internet search. The censor blocks requests that either contain flagged keywords (such as “Tiananmen Square” in China) or prohibited domain names (such as “Wikipedia” in many countries).

11 Types Of Muscle Tension That May Be Caused By Bottling Your Emotions:
1. Upper Back Tension
You are holding onto something very sad, this sadness has built up to the point where you are feeling it physically. Perhaps you need to let go of past heartbreaks or things of the sort? Did you refuse to allow those feelings to ride out as they should have?
2. Shoulder Tension
The shoulder is often associated with responsibilities and with good reason. The more weight you add on without acknowledging that you need help the worse this tension is going to get. You have to be able to ask for help when you need it, pretending everything is fine when it isn’t is not helping things at all.
3. Lower Back Tension
The lower back is where our insecurities grow. Have people been making fun of you? Do you hate something about yourself? These are things we all face, you shouldn’t be ignoring them but rather working through them. Accept yourself and everything will begin feeling better.
4. Abdominal Tension
This is basically tension or cramping in the stomach. It happens when we refuse to process something important. Just because it is hard does not mean we should pretend it didn’t happen; feel the things you need to feel.
5. Neck Tension
Neck tension is basically you refusing to deal with the stress at hand. It is building up and you are not releasing it as you should be. When this happens a lot of problems occur. Do you wake up with serious neckaches on the daily?
6. Middle Back Tension
If you are feeling tension here you are most likely refusing to deal with a guilty conscience. Have you done something wrong? Is there something you need to own up to? We all make mistakes in life, there is nothing that cannot be forgiven in time.
7. Head Tension
Tension in your head stems from fear. What are you afraid of? Is something bothering you that you aren’t even aware of?
8. Wrist Tension
Wrist tension is one of the more common issues people seem to face. We deal with tension here when we are upset and angry. Anger manifests itself whether we are aware of it or not. If someone or something is pissing you off, your body knows.
9. Outer Thigh Tension
This is where your past seems to haunt. Any sense of betrayal you have experienced but ignored makes its way here. If this is happening to you, you need to figure out how to get over it.
10. Inner Thigh Tension
This is where your impatience comes in to play. Are you being too pushy? This stems from being frustrated and is something a lot of people struggle with. It is one of the easier tensions to relieve believe it or not.
11. Knee Tension
Now, tension in the knee can be a bit tricky. For the most part, it seems to stem from being afraid of showing your vulnerable side and bottling it away. There is nothing wrong with being vulnerable sometimes. Stop being afraid to feel things.
Shinji Nakaba has been making brilliant pieces of jewelry, and everything he designs is wearable. If you ask the Tokyo-based artist, he will say his creations are “wearable sculptures.” The artist uses unconventional material for his creations, and pearls are probably his favorite.
Nakaba’s primary goal is to give life to common materials. He uses precious metals, stones, aluminum beer cans, plastic bottles and other pieces of garbage. That’s what makes his creations so special.
Nakaba started carving corals, crystals, ivory and other precious stones. Pearls without cores turned out to be his favorite. These pieces provide smooth carving, and there’s almost no risk of shredding or peeling.
The artist notes that he has experimented with different materials to carve out skulls, adding that pearls are most durable. Turning pristine pearls into skulls is a completely different approach, and it outlines the link between the pure and the dark.
You can find a lot of creations on Nakaba’s website, and you can pick your favorite. He makes necklaces, rings and even brooches. Oh yes, he is also great in arranging flowers. Have you ever heard of ikebana jewelry?
Artists like Nakaba give us a different definition of life and art. Every type of art is special, but how often do you see pearls carved into skulls? We’d definitely like to have one of these.

At a meeting of the Royal Geographic Society of London, Earthwatch Institute declared bees the most invaluable species on this planet, as reported by The Guardian in 2008. And along with it comes this disturbing piece of news. If the bees were to disappear today, mankind would follow suit very soon!
Scientists and wildlife experts have joined bees to the list of species that are doomed to extinction in the near future if humanity does not do something about its most beneficial insects.
The Importance Of Bees
The loss of bees will be disastrous for mankind as they are irreplaceable. The relation between bees and flowering plants is one of the most extensive, harmonious, and interdependent cooperation on the planet. A relationship spawned over a period of nearly 100 million years has led to the procreation of a rich diversity of species and also promoted the elevation of the human species on earth.
There are more than 20,000 species of bees. Yet, an overwhelming number of them do not live in hives. They vary in size from 2mm to 4cm and do not adapt well to new plant types.
75% of the food crops that produce the seeds and fruits we consume are influenced, at least partly, by pollination. 87 of the leading food crops worldwide are supported wholly or partially by pollination. This, in turn, feeds thousands of animal and bird species. They are the main reason for the diversity of plant species. The decline in the bee population would adversely affect major crops like coffee, cocoa, almonds, tomatoes, and apples to name just a few, as per the reports of the Food and Agricultural Organization of the United Nations (FAO).
The oldest known sweetener and also the healthiest, honey has been much sought after since ancient times. The total export of just leading honey-producing nations was worth $2.4 billion way back in 2009. This is another vast source of food that would just disappear with the bees.
The monetized value of the global crops that are directly dependent on pollinators is in the region of $235 billion to $577 billion every year. This was a free gift of nature. Relying on the artificial process is close to impossible. The only way out is to support the process which leads to natural pollination.
We have already let loose processes that may in the not too distant future lead to the extinction of the planet’s leading pollinator and with it the extinction of countless other species including man. The need to sustain our ever-increasing population has led to the use of methods to increase production at any cost, especially the clearing of forests for farmland and the incremental use of pesticides. 40% of the invertebrate pollinator species, especially bees are facing extinction. This has led to a steep decline in the population of both wild and domestic bee population. Vast populations have been decimated in some parts of the globe.
The transmission of pests and pathogens from other areas due to globalization has affected the population of bees in some areas. The waves produced by mobile telephones are being blamed. The Federal Institute of Technology of Switzerland says that bees are disoriented by waves emitted during calls. Daniel Favre, Biologist, and other researchers produced evidence that showed that bees were disturbed and warned other bees when exposed to the waves, as reported in The Australian.
A total prohibition on the use of toxic pesticides, especially neurotoxins and using natural alternatives is the immediate necessity. Pollinator-friendly practices in agriculture are a must. Farmers need to be aware of the pollination needs of specific crops and act accordingly. Wildlife habitats must be preserved. Farmers can diversify farms to make food resources always available for the bees. The need for restoring ecological friendly practices must be encouraged. This will preserve the habitats of the pollinators.
Today was a little bit of a random day in Addis Ababa, Ethiopia, searching for delicious Ethiopian food. I first met up with Sam, and he took me a little outside of town, an area known for their meat. We asked some locals around, and found a local meat restaurant that everyone agreed was the best in the city. Dulet – Dulet is an Ethiopian food of minced up raw organs, sauteed in Ethiopian spiced butter. It’s incredibly delicious. The the man sitting next to me ordered shekla tibs, a pan of sliced meat fried and served in a charcoal clay pan. It was very chewy, but tasty. Total price – 230 ETB ($8.31) including drinks Tej – Tej is traditional Ethiopian honey wine, and after asking, some people told us there was a local Ethiopian bar just down the road. It was quite an Ethiopian cultural experience. Price – 9 ETB ($0.33) per cup El Shaday Restaurant – Finally, we returned to Addis Ababa, in the center of the city, and searched out an Ethiopian food that I had desperately wanted to eat – called Tihlo. It’s a dish from Tigray, very rare to find in Addis Ababa, and even the friends I was eating with, who are all Ethiopian, had never heard of it, or tried it. So it was a first for all of us. Turned out to be incredibly delicious, and now one of my favorite new Ethiopian dishes. Price – 80 ETB ($2.89) Thank you for watching this unique Ethiopian food tour in Addis Ababa, Ethiopia!
