Donating Blood can actually make you healthier! Pixabay

Donating blood and staying healthy go hand in hand; thousands of people require blood every day in India but face a dilemma as the number of donators is comparatively less. Only one blood donation can save three lives.

Apart from regular blood donation one can also donate platelets which are done through a machine which filters the platelets and transports the blood back to the donor. This whole process takes around 70-90 minutes whereas a non-platelet donation takes only 45 minutes. Blood donors are supposed to 18 or above and are permitted to donate blood till 60 years of age in India.

Many are unaware that the process of blood donation is beneficial for both parties. Let’s talk about some health benefits of donating blood:

1.Reduces the Risk Of Cancer

One of the great benefits of Donating blood is, It can reduce the risk of cancer as the reduction of iron and iron stones in our body prevents the damage iron has been said to cause. According to a study published in the the Journal of the National Cancer Institute iron has been believed to increase free radical damage in our body and aging. A research conducted showed that a group of people who donated twice a year reduced their iron stores twice whereas another non donor group did not. The former group showed lower signs of cancer. The donation of blood is linked to the reduction in oxidative stress which is harmful.

2. Protects and Preserves your Cardiovascular Health

A unifying factor for the risk of cardiovascular diseases is blood viscosity according to the Harvard Medical School Family Health Guide. The damage done to your cells lining the arteries can be determined by how sticky and thick your blood is and how much friction is created through the vessels. The other benefits of Donating blood is, it decreases the blood viscosity and gets rid of the iron that could oxidize our blood. Oxidative stress damages our cardiovascular system. Blood donation also decreases the risk of hearts attacks and strokes specially participants aged between 43 & 61.

3. Calorie Burn

According to the University of California, One donation of blood can burn approximately 650 calories. A regular donor can lose a significant amount of weight but this is not a means of weight loss plan at all. In India, 50 kgs are the minimum weight required to donate blood. The donor should also maintain healthy iron levels in their body.

4.Free Blood Check-Up

Before donating; donors are tested for HIV, syphilis, hepatitis and other diseases. Without testing, one cannot be eligible to donate blood as it is necessary to know what is in your bloodstream. Your blood can also be used for tests and research in the future upon your consent. So, here is one more benefits of donating blood, you can get your blood tested for free.

Bangladesh over the years show that the state has failed in its duty to protect minorities

If humanity is hurt, God is hurt.

Religion without compassion might give way to hatred. Compassion with a "self-interest" motive is completely irreligious. But of late, some of the religions have departed from those basic human values. Love and compassion are for only those who follow their "specific" faith. Very sadly, the religions are up as trading commodities in the world of proselytization. Better preachers attract more followers. Of course, no issue if they are not vying for their religious "supremacy". But the ground reality is utterly different. The claim for exclusive supremacy has become the first commandment --- a real bone of contention among the existing religions. In the name of religion, we have polluted our minds. we have corrupted our souls. We have also gone so much astray that God must have now shut his gateway to heaven!

Taking out time for family has become very difficult as people are pretty busy in daily life and find very little time to spend with their loved ones. Planning a family vacation is an excellent way through which the whole family can step away from their daily life and have fun. You can find many destinations for a family vacation, but there is no place that can beat Aruba.

Milky Way galaxy as seen from Chitkul Valley

NASA's Chandra X-ray Observatory has for the first time spotted signs of a planet transiting a star outside of the Milky Way galaxy, opening up a new avenue to search for exoplanets at greater distances than ever before.

The possible exoplanet -- or planets outside of our Solar System -- candidate is located in the spiral galaxy Messier 51 (M51), also called the Whirlpool Galaxy because of its distinctive profile, NASA said in a statement.

Astronomers have, so far, found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all of them less than about 3,000 light-years from Earth.

An exoplanet in M51 would be about 28 million light-years away, meaning it would be thousands of times farther away than those in the Milky Way, NASA said.

"We are trying to open up a whole new arena for finding other worlds by searching for planet candidates at X-ray wavelengths, a strategy that makes it possible to discover them in other galaxies," said Rosanne Di Stefano of the Center for Astrophysics at Harvard and Smithsonian (CfA) in Cambridge, Massachusetts, who led the study.

The findings are published in the journal Nature Astronomy.

The exoplanet candidate was spotted in a binary system called M51-ULS-1, located in M51. This binary system contains a black hole or neutron star orbiting a companion star with a mass about 20 times that of the Sun. The X-ray transit they found using Chandra data lasted about three hours, during which the X-ray emission decreased to zero.

Based on this and other information, the team estimates the exoplanet candidate in M51-ULS-1 would be roughly the size of Saturn and orbit the neutron star or black hole at about twice the distance of Saturn from the Sun.

The team looked for X-ray transits in three galaxies beyond the Milky Way galaxy, using both Chandra and the European Space Agency's XMM-Newton. Their search covered 55 systems in M51, 64 systems in Messier 101 (the "Pinwheel" galaxy), and 119 systems in Messier 104 (the "Sombrero" galaxy).

However, more data would be needed to verify the interpretation as an extragalactic exoplanet. One challenge is that the planet candidate's large orbit means it would not cross in front of its binary partner again for about 70 years, thwarting any attempts for a confirming observation for decades, NASA said.

Named in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar, the Chandra X-ray Observatory is the world's most powerful X-ray telescope. It has eight times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope.

Known to the world as Chandra (which means "moon" or "luminous" in Sanskrit), Chandrasekhar was widely regarded as one of the foremost astrophysicists of the twentieth century. (IANS/JB)
