Finkelstein S.L et al., Nature, October 2013

Astronomers have recently spotted a faint ray of light using the Hubble Space Telescope, a ten-meter telescope at Keck Observatory, located at the summit of Mauna Kea, a dormant volcano in Hawaii. Analysis of light showed that it was a galaxy formed 13.1 billion years ago, which is only 700 million years after the Big Bang, when our universe came into existence. This is so far back in time, it would be about 8 billion years before our sun was born. The new galaxy is called z8_GND_5296, and it is the oldest and most distant galaxy ever discovered. Because the universe is expanding, the lights coming from distant objects would be stretched, and their wavelengths changed, as they travel through the expanding universe. This phenomenon is called Redshift. It makes visible light look redder, and redshift increases proportionally with the distance to an object. Lights coming from z8_GND_5296 looked more redshifted than anyone had seen before. More detailed analyses showed that the mass of gz8_GND_5296’s stars was equivalent to 1 billion suns, which is approximately 50 times less than the Milky Way’s stellar mass. Even more surprisingly, the new galaxy is found to have an unusually high star-formation rate. This rate is typically calculated by how much raw hydrogen the galaxy yearly converts into new stars. gz8_GND_5296 converts hydrogen 300 times the mass of our sun, while the Milky Way produces 1 or 2 solar masses per year. One of the explanations for this extraordinary star-formation rate is that the early galaxies contained or drew in much more gas than scientists expected. The search for distant galaxies aims to find the very first galaxies formed after the Big Bang, perhaps the ones that produced the first natural elements. To this end, NASA plans to launch the James Webb Space Telescope (JWST) in 2018. JWST will reside in an orbit 1.5 million km from the earth and hopefully it will help astronomers to look further and further back into the origins of the Milky Way, and ultimately, the history of our universe.

Vast Freshwater Reserves Found Under Ocean

Offshore fresh groundwater reserves as a global phenomenon.
Post V.E.A et al., Nature, December 2013

As earth’s population rises, we face a serious problem of fresh water supplies. The United Nations predicts that half of the world will be struggling to find clean, fresh sources of water by 2030. Luckily, Australian scientists discovered huge freshwater reserves, and in the most unexpected place: under the ocean floor. Newly discovered reserves are estimated to contain 500,000 cubic kilometers of low-salinity water, located off the coast of South Africa, North America, Australia, and China. This vast reserve is approximately 100 times greater than the volume of the fresh water used since the beginning of the 1900s. This water reserve is thought to develop earlier in Earth’s history, perhaps over thousands of years, when oceans were not that deep and when the coastline was further out. Scientists hypothesize that rainwater leaked through the ground and had created these fresh water aquifers beneath layers of porous rock and/or soil. Around 20,000 years ago, the polar ice caps began to melt and these regions were covered by ocean. Fortunately, layers of either clay or sediment seemed to protect the reservoirs from salty contamination: the salinity of this water is low enough to be readily transformed into drinkable water. These water reserves can be extracted by constructing drilling platforms, either at sea or from the mainland, close to aquifers. However, drilling projects are usually very controversial due to environmental and economic costs. Scientists are currently seeking alternative, more environment-friendly ways to use these reserves. Nonetheless, mankind may have found a new vital water resource for the future.

Crows Don’t Forget a Face; Crow Intelligence Decoded

Abstract rule neurons in the endbrain support intelligent behavior in corvid songbirds.
Veit L. and Nieder A., Nature Communications November 2013

Scientists have long suspected that members of the corvids – a family of birds that includes ravens, crows and magpies – are extraordinarily intelligent. They make and use tools, remember multiple feeding locations, and exhibit highly social behaviors. Last year, scientists even demonstrated that crows captured in Seattle would never forget the face of their abductor and they would still taunt and dive-bomb the threatening face several years after the incident. To understand the mechanism of crows’ amazing face recognition process, neurobiologists designed an experiment, in which they trained the crows to perform memory tests on a computer. The crows were first shown an image and shortly afterwards, they had to select one of two test images on a touchscreen, using their beaks, based on switching behavioral rules. One of the test images was identical to the first image; the other one was a different image. Sometimes, the rule of the game was to select the very same image, and sometimes it was to select a different one. Remarkably, the crows were able to carry out both tasks and to switch between them almost perfectly. These tasks require a high level of concentration and mental flexibility that few animal species can manage – they even require a great effort for humans. By recording single-unit neuronal activity from an association area of the crow’s brain, known as the nidopallium caudolaterale (NCL), the researchers were often able to guess which rule the crow was following, even before the crow made its choice. The cerebral cortex in human brain is very large and it is thought to be home to complex cognitive functions including face recognition. However, since a bird’s cerebral cortex is much smaller than humans, people long thought that birds could not perform intelligent tasks. This study shows that birds use a unique non-cortical brain region, nidopallium caudolaterale (NCL), to sort sensory information and decide how to react.

As sleepers floated in their deepest slumbers

In purple and pink, successive dawns were swelling

While in waters swans were elegantly gliding

We felt the shivering breaths of a new spring.

A cerulean serenity had enveloped our dreams

And the sky winked with hope from a distance

In a moment, we were left without defenses

At the point where providence meets resolve

God made our dreams bloom.

The overflowing fountain has come to life again

Breezes high and low promising a bright future

Everywhere embraced by a blessed joy

And the happiest days of life I longed for

Were being lived in the deepest sense, once again.

A pristine spring, with its fresh verdant hues

Like the patterns and colors of the past

The people found the touchstone they had lost

Making up for the great loss they sought

Purple rosebuds on heavenly hills.

With the breeze blowing, now grasses atone

In the lands, once struck lifeless by autumn, are new roses

As if the Trumpet has blown, the dead are resurrected

Along with them in this azure dream

Grieving hearts attain reunion. 

Cherries are grown as one of three types: sweet, sour, or wild cherries. Alongside fresh cherry consumption, cherries are also used in juices, jams, jellies, cherry pies, cakes, ice cream, and so on. Cherries are healthful and rich in minerals. A hundred grams of cherry juice contains 246 kilocalories, 58.3 grams of carbohydrate, 3.12 grams of protein, 1 gram fat, 115 milligrams of sodium, 745 milligrams of potassium, 0.5 milligrams of vitamin C, 64 milligrams of calcium, and 81 milligrams of phosphorus. They are rich not only in folic acids, which play a significant role in producing nucleic acids and in the conversion reactions of certain amino acids, but also in potassium, which is needed for osmosis of bodily fluids and acid-base balance. Ripe cherry fruits have been widely used as a traditional medicine to relieve pain, especially in Western Europe and North America.

Cherries as a rich source of antioxidants

Antioxidants are vitamins, minerals and other compounds found in foods that can slow down the oxidation process. During the oxidation process that our body goes through in order to metabolize fats and glucose so they can turn into heat and energy, the body constantly produces free radicals as a byproduct of normal metabolism. Antioxidants help prevent the damage done to the body’s cells by such naturally occurring free radicals as super oxides. The super oxide exposure of a person weighing 70 kilograms amounts to about 1.72 kilograms on an annual basis.

Free radicals are unstable substances with missing electrons. They seek to balance themselves by stealing electrons. In constant need of electrons, free radicals take electrons from our healthy cells. Damage to healthy cells caused by free radicals plays a major role in the aging process as well as in the onset of many ailments. Antioxidants provide the electrons that these free radicals need so they can leave the electrons from your healthy cells alone. Protecting the body against free radicals’ mass conversion of cells, antioxidants help reduce the risk of various degenerative diseases caused by free radicals, boost the immune system and improve our health.

God Almighty has created all the cells of the body containing complex systems of antioxidants to prevent chemical damage to the cells’ components by oxidation. Our body is created with an ability to produce metabolic enzymes which are extremely effective antioxidant scavengers. However, the body produces more free radicals and fewer antioxidant enzymes after the late twenties. The All-Providing God has granted us many antioxidant-rich food products that may help us maintain a high quality of life, especially as this ability of the body to generate these enzymes fades dramatically with age.

Ranking above most fruits, cherries are an excellent antioxidant food. There are fourteen compounds in cherries with antioxidant properties. These compounds can protect the body against degenerative diseases, including cancers and cardiovascular disease. One of the more powerful antioxidant compounds in cherries is anthocyanin. In just one liter of cherry juice, there are 267–688 milligrams of anthocyanins that also give the fruit its bright red, red, purple, or violet color.

Recently, as awareness has been raised of most fruit and vegetables having natural antioxidants, and that cherries especially are a rich source of naturally occurring antioxidants, the use of such food products has become more common than synthetic antioxidant supplements.

More health benefits

Cherries offer other major health benefits. They contain the powerful antioxidant compound melatonin, which has anti-inflammatory properties and which controls daily circadian rhythms, helping to improve sleep patterns. Alongside their anti-inflammatory health benefits and improving sleep, they also provide pain relief. Research shows that the consumption of an average of twenty fresh cherries or some cherry juice is much more effective than aspirin in reducing pain caused by inflammation, arthritis or gout.

Cultivation, consumption, and storage

Cherry trees grow in a wide range of climatic conditions and are indeed easy to grow from seed. Once the cherry plant has established, it reaches the fruiting stage in several years.

Cherries can be consumed or stored in a great many ways. Alongside cherries eaten fresh or dried or the juice from the fruits, they can also be used in many dishes, especially desserts, jams, and marmalades. While buying cherries, select fresh, unblemished fruit. Besides consuming cherries as a fresh fruit item, they can also be kept in frozen fruit packs or in cans. Cherries that are to be saved can be stored in the freezer in airtight bags. Canned cherries are also available preserved in sugar syrup. Sweet cherries are particularly used in cakes and puddings. Sour cherries are generally candied or preserved.

– Is there fresh bread and cold, fresh water like this on the tables of our fighting brothers, or have you offered me such a table just because I am the commander?

– We set aside that bread and water for you, o Commander, they answered.

This answer made Abu Ubayda angry and, pushing the table away. he commented:

– I cannot conceive of a behaviour worse in the sight of God Almighty than sitting at a table different from what is offered to our brothers shedding their blood in the way of God in the same lines with us. I could not sit at such a special table even if I were the Caliph, not a commander.

Bediuzzaman Said Nursi, the famous Muslim scholar and thinker, who launched a major Islamic movement of revival in Turkey in the second quarter of this century, offered this challenge to those who deny the Prophethood of Muhammad, upon him be peace and blessings:

Consider how, eradicating their evil and savage customs and immoral qualities to which they were so fanatically attached, he equipped and adorned the desperate, wild and unyielding peoples of the seventh century Arabian Peninsula with all the praiseworthy virtues, and made them teachers of all the world and masters to, especially, the civilized nations.

His was not an outward domination; rather, he conquered their minds, spirits, hearts, and souls. He became the beloved of hearts, the teacher of minds, the trainer of souls, and the ruler of spirits.

You know that despite all the advanced techniques and methods, modern communities are unable to remove permanently so small a vice as cigarette smoking. However, the Prophet Muhammad, upon him be peace and blessings, with apparently little effort over a very short period of time removed numerous ignoble habits from large communities in whom those habits were long ingrained, and in their place implanted and inculcated noble qualities in such a way that they became inherent in their nature. To those who refuse to see the testimony of the blessed age of the Prophet, upon him be peace and blessings, we present as a challenge any part of today’s civilized world. Let them go there with hundreds of philosophers, sociologists, psychologists and pedagogues and educators, and strive for a hundred years. I wonder whether they will be able to achieve in that period a hundredth part of what the Prophet Muhammad achieved in a year.

Abu Bakr, in the early days of his Caliphate, managed on the wage he earned by milking the cattle of one of his neighbours. Some time later, some Companions led by ‘Umar made him this offer:’As the Commander-in-chief of the Muslims, you have much work to do. Therefore, give up milking cattle and let us assign a fixed salary for your needs as Caliph.’

Abu Bakr spent from this salary for his living expenses and stored any surplus in a pot. He told those around his death-bed to hand that pot over to the one nominated to replace him as Caliph.

Umar was chosen after Abu Bakr. During his rule, Islam spread as far as Afghanistan in the east and Caucasia in the north. One evening during the holy month of Ramadan, ‘Umar was a guest of one of the Companions. When he was offered a sherbet of honey, he refused it, saying:

‘I can drink this only when all of the people, the responsibility of governing whom I shoulder, have become so rich that they can drink the sherbet of honey with their meals.’
