Pune, Feb 15: A Pune-based woman's world came to an unexpected standstill when her son succumbed to cancer two years ago in Germany. But her joy knows no bounds now.

She became a grandmother to twins born via surrogacy methods using her son's cryo-preserved semen.

Doctors at Pune's Sahyadri Hospital performed the in-vitro fertilisation (IVF) procedure and fused Prathamesh Patil's semen, extracted and preserved long before his death in Germany, with the eggs of a donor to form embryos.

The embryos were then transferred into the womb of a surrogate mother, who gave birth to the twins - a boy and a girl - on Monday.

Prathamesh Patil's mother Rajashree Patil said in 2010 her son had gone to Germany to pursue a master's degree when he was diagnosed with a brain tumour.

"The news was a shock to our family. Health experts in Germany suggested that Prathamesh start chemotherapy and radiation procedures. They also asked him to preserve his semen to avoid any negative effects on his body post-treatment," she said.

However, he suffered convulsions and also lost his vision, said Rajashree Patil, who teaches at a school in Pune.

"After getting to know about his condition, which was stage-four cancer, as informed by medical officers there, my first effort was to bring Prathamesh back to India from Germany," she said.

The family brought the ailing Prathamesh to India in 2013 and took him to a hospital in Mumbai, where he was operated upon following which his health showed signs of improvement.

"However, in between, he suffered another convulsion and was detected with a recurring tumour. He succumbed to a malignant tumour in September 2016," the mother said.

After his death, the mother, having a desire to get back her son, contacted the semen bank in Germany where Prathamesh Patil's semen was cryo-preserved.

After completing the formalities, the semen was brought to India.

The mother then approached Sahyadri Hospital for an IVF procedure with the help of his son's semen.

Supriya Puranik, the head of IVF, gynaecology and obstetrics department at the hospital, said she is happy that advancement in science and technology is bringing a smile on people's face.

"In hospitals, we often see a lot of emotional moments and happiness whenever a woman delivers a baby and we become a part of their joy," she said.

"But in this case, it was about a grief-stricken mother whose son was away for studies when he faced health issues and later died," said Puranik.

"We appreciate the kind of spirit she has shown in this entire process and we congratulate her for having her son back in the form of these healthy twin babies," she added.

Dubai, Mar 18: Emirates, one of the world's biggest international airlines, has asked pilots to take unpaid leave to help it mitigate the impact of the coronavirus pandemic that has shattered demand for global travel.

"To this end you are strongly encouraged to make use of this opportunity to volunteer for additional paid and unpaid leave," the airline said in an internal email to pilots, seen by Reuters.

Emirates earlier this month asked some staff to take unpaid leave, although at that time it was not available to pilots.

New Delhi, Mar 10: A military transport aircraft of the Indian Air Force (IAF) brought back 58 Indians from coronavirus-hit Iran on Tuesday, official said.

The aircraft, a C-17 Globemaster, was sent to Tehran on Monday evening.

About 2,000 Indians are living in Iran, a country that has witnessed increasing numbers of coronavirus cases in the last few days.

"The IAF aircraft has landed. Mission completed. On to the next," External Affairs Minister S Jaishankar tweeted.

In an earlier tweet, he said, "First batch of 58 Indian pilgrims being brought back from Iran. IAF C-17 taken off from Tehran and expected to land soon in Hindon."

"Thanks to the efforts of our Embassy @India_in_Iran and Indian medical team there, operating under challenging conditions. Thank you @IAF_MCC. Appreciate cooperation of Iranian authorities. We are working on the return of other Indians stranded there (sic)," Jaishankar added.

The aircraft landed at Hindon airbase in Ghaziabad, from where the passengers were take to a medical facility.

According to latest reports, 237 people have died of novel coronavirus in Iran while the number of positive cases stands at around 7,000.

It is the second such evacuation by the C-17 Globemaster in the last two weeks.

On February 27, 76 Indians and 36 foreign nationals were brought back from the Chinese city of Wuhan by the aircraft of the Indian Air Force.

The C-17 Globemaster is the largest military aircraft in the IAF's inventory. The plane can carry large combat equipment, troops and humanitarian aid across long distances in all weather conditions.

Four days ago, a Mahan airline plane brought swab samples of 300 Indians from Iran to India.

Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.
