Is it true the Diamond is not scarce?

Diamonds are always associated with expensive and luxurious. For men, buy diamond encrusted jewelry for their girlfriend or wife a sign of wealth. It was impressive that the diamond is a rare gem. But in fact, not entirely correct.

As quoted from Science Daily on Sunday, November 8, 2015, according to the findings of the Johns Hopkins University, diamond is not rarest as we imagine.

"Formation of diamonds in the ground, piece of land very deep, it could be more common than we think," said Dimitri A. Sverjensky, a geochemist from Johns Hopkins University.

The articles written by Sverjensky with doctoral candidate student Fang Huang published in the online journal Nature Communications. Report 'is a new quantitative theory in the formation of diamonds'. However, that does not mean you necessarily can easily find diamonds and bring it to market, and then go home with a lot of money.

The existence of diamonds in the ground is not a bit, however, whether or not taken depends on several things. One of them, whether or not the volcanic eruption of magma at a depth where diamonds. Others, diamond mentioned in the study is not only the type of diamonds used for jewelry, but when present it, is equipped with a microscope. In other words, not all types of diamonds are considered 'precious stones'.

By using models of chemicals, Sverjensky and Huang found that these precious stones can be formed in a natural chemical reaction that is simpler than the two main processes, which until now believed to be a diamond formation. Specifically, the model, which will be tested with real material, showed that diamonds are formed with rising levels of acidity in the interaction between water and rock.

The common understanding until now is that diamonds are formed in a fluid movement with reduced oxidation of methane or chemicals from carbon dioksisa. Oxidation produces a higher oxidation state, or increasing the electron. Keasaan oxidation reduction means lower, and the second reaction process called 'redox'.

"It is always difficult to explain why the redox," said Sverjensky, who is also a lecturer in the Department of Earth Science and Planet in Morton K. Blaustein. The reaction requires a different type of fluid that can be moved through the rock, to the environment that have different oxidation states.

Recent research shows that the water could produce diamonds because of the level of acidity (pH), which falls naturally, so it becomes more acidic while moving from one stone to another.

This discovery is one of the discoveries for 25 years, which gives insights into the nature of the diamond easily deformed. "More and more people are looking for, easier to find diamonds in different types of rock," said Sverjensky. "I think all would agree that more and more the environment in which the discovery of a diamond formation."

No more that reveal the number of diamonds greater availability, but according Sverjensky scientists today continue to work with chemical models. Not possible to physically explore the depths where diamonds are created - approximately 90 to 120 miles below ground level, with strong pressures and temperatures reached 1,650 to 2,000 degrees Fahrenheit (900 to 1,100 degrees Celsius).

Whereas, for the moment, the underground exploration of the deepest ever done is 8 to 9 miles below the surface. *** [EKA | FROM VARIOUS SOURCES | SCIENCE DAILY]

Renault presented a concept of Super-Futuristic Coupé

Renault has recently introduced a concept of their 'radical' future sedan design named 'Coupé Corbusier,' the concept car is created and displayed for the 50th anniversary of the death of the famous French architect, Le Corbusier.

Renault said that they have no plans to turn the concept car into a production version, because the Corbusier Coupé only as part of a styling exercise those allowed designers to develop the future concept cars with 'more relaxed'.

Renault Coupé Corbusier is a slim-bodied two-door car, but with a long bonnet, large front grille and prominent windshield and narrow diameter windows.

Meanwhile, the side view of the Coupé Corbusier also looks very 'muscular', thanks to the presence of the bulging wheel arches that look quite spectacular when its dihedral doors opened.

Because it's just a styling exercise, Renault Coupé Corbusier most likely not have a powertrain configuration. In addition, the cabin is expected to follow the same theme as the exterior, so the layout is futuristic with many featuring touchscreen likely to be encountered here.

Renault says the Coupé Corbusier Concept currently being exhibited at the Villa Savoye in Poissy, France, as part of the exhibition titled 'Des voitures à habiter: mobil et modernisme XXe-XXIe siècles', or roughly means: Cars in life: the presence of cars and modernism in the 20th and 21st centuries, which will be held until March 20, 2016. *** [EKA | FROM VARIOUS SOURCES | AUTOCAR]

Love Caused Chemical Changes in the Brain

When somebody to fall in love or see our relatives who are in love, it seems there are changes that we can feel. It seems difficult to find something rational because no less a person who is in the lovelorn looks a little "crazy". Apparently, fall in love caused chemical changes in the brain.

Helen Fisher, an anthropologist professor at Rutgers University along with two her colleagues, using MRI machines to study the brains of people who said that he was in 'heavy' love. When the research subjects look at pictures of her lover, the ventral tegmental area and the nucleus caudal will "light up". Caudal nucleus is an area of ​​dense network of receptors for the neurotransmitters dopamine.

Donatella Marazziti, a psychiatry professor at the University of Pisa in Italy is also doing research. She measured the levels of serotonin in the serotonin neurotransmitters in the blood of people who are in love for a few months and his mind filled with his lover for a few hours each day.

In that study, Marazziti found that serotonin levels in people who are at equally low lovelorn with serotonin levels in people suffering from obsessive compulsive disorder or some sort of obsessed with something in excess (coercive).

A group of scientists from China and New York used brain scans from 100 people to map out the brain in love -- and the brain falling out of love.

"LG" indicates the brain of a person in love, "SG" indicates the brain of single person, and "ELG" indicates the brain of a person who recently fell out of love. The color red highlights areas with high levels of brain activity. (Picture from: http://huff.to/1kcWUXx)

The findings, which were published online in the journal Frontiers in Human Neuroscience last month, revealed that people who were deeply in love and those who had recently broken up with their partner showed differences in a number of brain regions, particularly some that make up the brain's so-called "reward center" and are involved in emotion regulation and feelings of motivation and pleasure.

Here's how falling in (and out) of love affects brain activity.

Falling in love: When a person is in love, there tends to be increased activity in the brain's "reward center," likely because they are experiencing a great deal of pleasure. One area of increased activity was a part of the brain that is active when someone first detects something rewarding (in this case, a love interest) or is expecting a reward (for instance, a special night out with said love interest).

The brain activity of people in love suggests that "they feel more rewarded, are more emotional and attentive, show higher motivation and are more engaged in social interaction," Anna Zilverstand, a post-doctoral fellow at the Icahn School of Medicine at Mount Sinai and a co-author of the study, told The Huffington Post.

Breaking up: After a breakup, activity in the brain's reward center decreases, indicating a drop in pleasure. A particularly sharp decrease in activity and functional connectivity was observed in a part of the reward center associated with the expectation of rewards.

So, if being lovesick and we feel like "insane", there is a scientific explanation, because falling in love is indeed caused chemical changes in the brain. *** [EKA | FROM VARIOUS SOURCES | HUFFINGTON POST | NATIONAL GEOGRAPHIC INDONESIA]

This helmet muffled the dangerous sound frequencies

The noise on the highway can not be underestimated,  because in the long term can lead to loss of hearing, stress, cardiovascular disease or at least mild fatigue.

Sena's intelligent motorcycle helmet keeps a lid on unwanted noise. (Picture from: http://bit.ly/1M4DmPP)

Sena, one of the well-known manufacturer with a communication system for the motorcycle rider, is now offering a helmet that can reduce the noise. Helmets are referred to as 'Sena Intelligent Noise-Cancelling (INC),' where this helmet will only isolate the harmful sound hearing and effectively reduce the noise below 100dB.

But motorists can still listen to the rush traffic voice that important to safety such as engine noise, horns, ambulance sirens even your nagging wife sound who is being carried on the back.

The Sena INC helmet is controlled by two buttons; the one on the left, above the ear cup powers on and off the INC system, while the right one controls the Ambient Mode. Lower on the left side is the Bluetooth connecting dock. (Picture from: http://bit.ly/1M4DmPP)

In the Sena INC helmet there are 4 speakers will analyze the annoying sound and dangerous for the sense of hearing. If readable as dangerous sound, system will enable the frequency of the speakers in each earcup that will eliminate the harmful frequencies earlier. Module system is placed on the lower back of the helmet.

However, the motorists can still listen to the sound naturally, such as talking with others when stopping or refueling. How, by utilizing the Ambient Mode, simply press the button on the left side of the helmet, without removing the helmet.

The system is embedded in the helmets made from carbon fiber, with EPS foam on the inside. Coated foam material soft washable fabric, namely COOL-Quick Dry fabric. In the system there is also Bluetooth communication system that can be connected with other Sena systems. The smart helmet quite light, weighing only 1.6 kg. And will be available early 2016. *** [EKA | FROM VARIOUS SOURCES | GIZMAG]
