Gaza: Motherhood is supposed to be a wonderful experience of life, but with lack of awareness and certain societal pressures giving birth can actually turn out to be an ordeal for some women that can even result in death.
A similar shocking incident has surfaced from Gaza, where a woman died bearing the brunt for lack of awareness about contraception and family planning. She lost her life after giving birth to her 69th child at the age of just 40 years.
While the unfortunate woman is said to be the most fertile woman as per statistics, a woman from Russia going by the name Vassilyeva holds the record of giving birth to 69 children, which involved 16 twins and seven sets of triplets with four quadruplets.
she was just 40

India’s only live volcano in the Andaman and Nicobar Islands which had started showing activity in the year 1991 after being dormant for over 150 years has once again started spewing ash, the researchers at Goa based National Institute of Oceanography (NIO) said today.
“The only live volcano in the Andaman and Nicobar islands is erupting once again. The Barren Island volcano, located 140-km north-east of Port Blair, dormant for more than 150 years started erupting in 1991 and has since then shown intermittent ctivity,” CSIR-NIO said in a statement here.
A team of scientists led by Abhay Mudholkar, from CSIR-National Institute of Oceanography (CSIR-NIO) in Goa reported that the volcano is active and spewing smoke and lava once again.
“On the afternoon of January 23, 2017, the scientific team on board CSIR-NIO’s research ship R V Sindhu Sankalp were busy collecting sea floor samples in the Andaman Basin near the Barren volcano when it suddenly started spewing ash,” the NIO has said.
“The team moved about one mile from the volcano and began closely observing it. It was erupting in small episodes lasting about five to ten minutes,” said the release.
During the daytime only ash clouds were observed.
However, after sundown, the team observed red lava fountains spewing from the crater into the atmosphere and hot lava flows streaming down the slopes of the volcano, it said.
NIO has said the volcano was revisited in the early hours of January 26, 2017 again during the second leg of the cruise led by B Nagender Nath, it said, adding the team witnessed the continuation of spurts of blasts and smoke.
“They have sampled the sediments and water in the vicinity of the volcano and recovered coal-like black pyroclastic material representing proximal volcanic ejecta.
Clouds were seen at the crater mouth where the smoke was bellowing out in otherwise clear sky,” the researchers said.
This makes the Earth’s satellite up to 140 million years older than previously thought.
The Moon is at least 4.51 billion years old — up to 140 million years older than previously thought, according to a new study of minerals called zircons brought back from the lunar body to the Earth by the Apollo 14 mission in 1971.
The Moon’s age has been a hotly debated topic, even though scientists have tried to settle the question over many years and using a wide range of scientific techniques.
“We have finally pinned down a minimum age for the Moon; it is time we knew its age and now we do,” said Melanie Barboni, research geochemist at University of California, Los Angeles (UCLA) in the United States.
Head-on collision created it
The Moon was formed by a violent, head-on collision between the early Earth and a “planetary embryo” called Theia.
The new study would mean that Moon formed “only” about 60 million years after the birth of the solar system, providing critical information for astronomers and planetary scientists who seek to understand the early evolution of the Earth and our solar system, researchers said.
That has been a difficult task, Ms. Barboni said, because “whatever was there before the giant impact has been erased.”
While scientists cannot know what occurred before the collision with Theia, these findings are important because they will help scientists continue to piece together major events that followed it.
How it was arrived at
It is usually difficult to determine the age of Moon rocks because most of them contain a patchwork of fragments of multiple other rocks. However, Ms. Barboni was able to analyse eight zircons in pristine condition.
She examined how the uranium they contained had decayed to lead and how the lutetium they contained had decayed to an element called hafnium.
The researchers analysed those elements together to determine the Moon’s age.
Zircons are the best clocks
“Zircons are nature’s best clocks. They are the best mineral in preserving geological history and revealing where they originated,” said Kevin McKeegan, a UCLA professor of geochemistry and cosmo-chemistry.
The Earth’s collision with Theia created a liquefied Moon, which then solidified. Scientists believe most of the Moon’s surface was covered with magma right after its formation.
The uranium-lead measurements reveal when the zircons first appeared in the Moon’s initial magma ocean, which later cooled down and formed the Moon’s mantle and crust; the lutetium-hafnium measurements reveal when its magma formed, which happened earlier.
Previous studies concluded the Moon’s age based on Moon rocks that had been contaminated by multiple collisions.
Professor McKeegan said those rocks indicated the date of some other events, “but not the age of the Moon.”
