Gravity, squid, and Blindness: What Is It Like Living in Space?

By: Syaifuddin Iqbal on 20:14

The resilience of the human body's mission in the International Space Station for a year was launched on March 27 and involved 19 medical and biological testing, 14 of which are designed by the Russian Space Agency. Cosmonaut Mikhail Kornienko and NASA astronaut Scott Kelly will also perform two experiments together. Most of the tests will be used by scientists to assess the ability of the human body during space travel for the preparation of long-term missions to Mars.

Famine in Space Without Gravity

As indicated by several previous trials, conditions of weightlessness affects human eating habits. Food does not have weight in space, so the astronauts feel hungry more often compared to when they were on Earth. According to Boris Afonin, scientific supervisor of food testing, increased appetite combined with a low amount of physical activity sometimes creates weight gain space explorers.

Another impact is the weightless conditions astronauts experience a change in their sense of taste while in space. "It's not salty foods into sweet or sour," said Afonin. "But astronauts often realize that the food they like while undergoing test trials on Earth invisible food tasty again. Some of them complained they were not getting pleasure from eating while on a mission. The cause of it is still to be us to investigate."

However, upon returning home, astronauts can not immediately eat beefsteak or borsht (typical Russian beet soup), as suspected people. "They need to adapt in advance, because after completing a mission in outer space, Earth digesting food takes hard work," said Afonin. "The reason weightless conditions also suppress the activity of the human digestive system, or in other words the intestine loses its ability to push the food."

However, according Afonin, all of it is just common assumptions, and that he supervised trials will determine which part of the human digestive tract are the most affected, including if there is a risk of pathological changes. The data will be used to figure out how to avoid dangerous changes in the digestive system and devise an optimal diet for astronauts.

Blood Flow to the Top

Russian scientists involved in the mission will also monitor the body's metabolism Mikhail Kornienko. Every two months, the cosmonauts will fill out a questionnaire regarding the consumption of water and food, take blood samples, and the results are displayed in a special tool called "sprut" (squid in Russian).

Data is expected to help scientists see how weightlessness affects the immune system and the endocrine system of man. "Even small changes in the endocrine gland can affect the performance of astronauts," said Galina Vasilieva, chief researcher at the Institute of Biomedical Problems of the Russian Academy of Sciences.

In addition, the effect of zero-gravity conditions also have an impact on the redistribution of human body fluids and can lead to dehydration. "The condition of weightlessness makes a large amount of blood is redistributed to the upper body," said Vasilieva. "All organs, including the liver, have to work harder. To adapt this regard, the body tries to get rid of excess fluid. As a result, on the first day of the mission astronauts showed an increase in the amount of urine."

When astronauts return to Earth, it is the other way: gravity ambushed and blood tend to be driven to the bottom of the body, so the astronauts could hardly stand on their feet after landing. The trials were conducted by the Russian team will help facilitate and accelerate adaptation in good condition in space and on Earth.

Too Easy Breathing

Another test conducted dubbed "UdoD" (a kind of colored birds in Russia). The first test done when astronauts are in zero-gravity conditions. These trials study the impact of the redistribution of fluid in the respiratory system and vision. Increased blood flow to the upper body causing intracranial pressure. This can result in reduced vision capabilities, which have been reported by several astronauts. It also happens when astronauts stood upside down.

As part of the experiment, Mikhail Kornienko will breathe using a special tool that is designed to lower blood pressure in the chest cavity and pushes the blood back down, said one of the Russian scientist Alexander Suvorov. "In a zero-gravity conditions, weakened respiratory muscles, the same as the leg muscles, because there is easier to breathe," Suvorov said. "UdoD designed to make greater efforts cosmonauts do breathe in weightless conditions, working like a sports machine," he explained.

Habib degree of proof Lineage DNA Through the Prophet

By: Syaifuddin Iqbal on 14:37

At the present time, we often hear the confession of a person as a descendant of the Prophet (Prophet Muhammad ibn Abdullah ibn Abdul Muttalib). In front of their names, there are usually additional Habib said, Sayyid or Sharif.

With the development of science, such a claim can be proven through scientific evidence, that the DNA test.

Meaning of DNA and Y-DNA Abdul Muttalib

DNA is short for deoxyribonucleic acid, which is a molecule that encodes genetic trait of an organism. When the human reproductive process, there will be a merger between DNA father and mother. Later this DNA will be passed down to succeeding generations continue (source: argaaditya.com).

Especially for DNA paternity, there is the term Y-DNA is the genetic code passed down from father to son.

Based on the Sirah of the Prophet, the Prophet had a daughter named Sayyidatuna Fatimah az-Zahra, who is the wife of Sayyidina Ali ibn Abu Talib bin Abdul Muttalib.

Through this family of Sayyidina Ali Messenger has 2 (grandchildren) male, named Sayyidina Hasan and Sayyidina Hussein, who became the ancestor zuriat Messenger at the present time.

When this has been found Y-DNA of the grandfather the Messenger and Sayyidina Ali, Abdul Muttalib with code (L859) (source: isogg.org)

The discovery of Y-DNA (L859) in a person, not sure he is a descendant of the Prophet. This is because, Abdul Muttalib has several other boys, who also inherited the Y-DNA.

Boys name Abdul Muttalib (Source: klikuk.com):

1. Abdullah (father of the Prophet Muhammad)

2. Abu Talib (father Sayyidina Ali)

3. Al Abaas

4. Al Haarits

5. Az Zubair

6. Hamzah

7. Abu Lahab

But a man who claimed to be descendants of the Prophet, should have this DNA code. And through DNA testing, at least can provide additional scientific evidence, for nasab someone, other than the written evidence is applicable for this.

Death and Aging Can Be Delayed

By: Syaifuddin Iqbal on 23:47

Frightening possible for us layman, but is a new thing at once breakthrough for scientists mreka. A death pastiakan toward all living beings on this earth, including humans. No one knows when death will datang.Tapi, a recent research conducted by researchers at the Institute of Health Aging at University College London, UK, gave birth to the new theory, the researchers discovered that the dying process occurs slowly. And, even more surprising, the death process can be delayed like we postpone the schedule of activities.

Worms as test objects while as quoted from several sources on the internet, the researchers see indications of the coming death of the worm that spreads through blue light on the cells in the body. The blue-colored liquid known as fluorescent, or a substance that has absorbed light or other electromagnetic radiation. Fluorescence is widely used in the fields of mineralogy, gemology, chemical sensors (fluorescence spectroscopy), fluorescent labeling, coloring, and biological detectors. The researchers observed the process of death worm did not occur in all parts of the body simultaneously, but slowly.

As a result of a disease, the cells in the worms die one by one. "We identified a chemical pathway that causes the destruction of the worm body cells die, that we can see from the fluorescent light that lights up in the body of the worm," said David Gems of the Institute of Health Aging at University College London, as reported by various media.

"The wave of death from intestinal worm starts then spread throughout the body. The more blue light that spreads throughout the body of the worm, the worm it will be closer to death, "Dr. Cassandra Coburn add, as the principal investigator of the research reported by The Huffington Post, July 26, 2013.

"When the fluorescent light was fading, then it indicates the worm was dead. But, we see the waning light occurs gradually, "explains Gems.Temuan raises new theory that the extinction of the fluorescent light can be blocked prior to postpone death, to rescue the cells that are still in good shape." This proves that the old age actually does not affect cells in the body. However, cell death is a parallel activity, ". "We're thinking of a way to disrupt the chemical processes that lead to death, so that death can be postponed," added Gems.Saat this, the team is focusing on studying the biological events that occur in the aging process of living beings.

Life prediction

Talk about aging, similar to the above study, another study researchers conducted a set of King's College, England, discovered new techniques in a blood test, which can predict how soon a person will grow old. Results of this study seemed to pave the way for the development of treatment of diseases associated with aging person.

Reported by the Telegraph, the research team has identified a chemical marker known as metabolites in human blood, which is closely linked to aging. The results showed one of 22 metabolites were found in human blood can indicate the condition of human aging.

Researchers also believe the new breakthrough in human blood testing can megindetifikasi problem of aging, or even death. According to Ana Valdes, principal researcher at King's College, 22 metabolites associated with aging detectable in the blood. "So, in the future we can predict a person's age and the aging of the blood samples". He explained that the metabolite is also specifically associated with lung function, bone mineral density, and weight at the time of the human birth. "It could be used to determine a person's age," said Valdes. as reported by the source.

This is the danger Eat Three Times a Day

By: Syaifuddin Iqbal on 12:41

Indonesia is a country whose population is most often eat three times a day. We are also accustomed to eating white rice at every mealtime. However, eating habits healthy is this?

It turns out that scientific studies indicate the presence of some harmful effects of the habit of eating three times a day that we usually do. Among these is a high likelihood of obesity and severe disease such as diabetes and stroke. Reporting from Dailymail, it is recommended eating habits is to slip a habit of fasting and rearrange diet we have.

The habit of eating three times a day accelerate the risk of obesity and severe disease via Asiantown

A journal Cell Metabolism describes that the trial eat every 8-9 hours can help you lose weight. The trial was conducted on obese mice. Meanwhile, the University of Southern California explains that the habit of fasting 2-4 days per six months can help boost immunity and metabolism better. This is because the body divert body system into a system of survival that makes the immune system increases

Eat as much as 3 times a day may actually be no harm, as long as we actually measure and determine what we eat. In fact, we are better advised to eat 6 times a day. Ie 3 main meals and 3 meals snack.

However, it should not be all of the major feeding sessions using white rice, because it can increase the risk of obesity and diabetes. Variations carbohydrate meal with brown rice, corn, potato or any other carbohydrate source is recommended. Pause between meals and consumption of food with one another as well sebaikya note.

Imagine if you just eat burgers an hour ago and now will enter into the stomach of warm rice. You will quickly glut, drowsiness and digestion will be burdened with an all-out. When digestion work hard, usually the body will reduce the power and it can make us susceptible to disease or virus.

Although eat three meals a day has become a habit, not all that unusual is healthy. So another evaluation of our diet and it could not hurt to run fast to boost the immune system that we have.
