ROCKET CARRYING SPACE STATION CREW FAILS IN MID AIR, CREW SAFE

A booster rocket carrying a Soyuz spacecraft with a Russian and US astronaut on board headed for the International Space Station failed mid-air today, forcing the crew to make an emergency landing.

The rocket was carrying US astronaut Nick Hague and Russian cosmonaut Alexei Ovchinin. Russian news agencies reported that the crew had safely made an emergency landing and were in radio contact and that rescuers were en route to pick them up.

"Search and rescue teams are in the air and heading towards the expected touchdown location for the Soyuz spacecraft returning to Earth carrying two crew members," NASA said in a statement.

NEW VIEW OF SPECIES INTERACTIONS OFFER CLUES TO PRESERVE THREATENED ECOSYSTEMS

A new analysis by scientists from around the world, led by a researcher at the University of California San Diego, is furthering science's understanding of species interactions and how diversity contributes to the preservation of ecosystem health.

A coalition of 49 researchers examined a deep well of data describing tree species in forests located across a broad range of countries, ecosystems, and latitudes. Information about the 16 forest diversity plots in Panama, China, Sri Lanka, Puerto Rico, and other locations many in remote, inaccessible areas had been collected by hundreds of scientists and students over decades.

The Researchers new "equal-area-annulus" method identifies pairs and groups of tree species that show unusually high or low levels of between-species interactions affecting their recruitment, mortality, and growth. 

"We explored how our method can be used to identify the between-species interactions that play the largest roles in the maintenance of ecosystems and their diversity." The interplay we have found between and among species helps to explain how the numerous species in these complex ecosystems can buffer the ecosystems against environmental changes, enabling the ecosystems themselves to survive.

GOVERNMENT WARNS AGAINST FAKE COVID-19 REGISTRATION LINKS ONLINE

The third phase of Covid 19 vaccination in India has started on May 1 all over the country. Many states have yet not received vaccines as they are still waiting to get fresh stocks from the vaccine manufacturers.

Taking advantage of this situation, fraudsters are ensuring covid vaccines. They are sending fraud and malicious Covid 19 vaccine registration links to users over different social media sites.

Warning against these links, Minister of State for Education, Communications, Electronics and IT, Government of India, Sanjay Dhotre has shared a post on Twitter. ''BEWARE! There are many web links being shared on social media claiming to ensure #CovidVaccine. Please do not click on any such links from unauthorized sources!'', he wrote on Twitter.

ONEWEB RECEIVES MAJOR INVESTMENT FROM EUTELSAT


OneWeb was bought out of bankruptcy last year by the British government and Indian conglomerate Bharti Global, with which Eutelsat will now share similar governance rights.


The investment also closes the gap in funding necessary for OneWeb to complete its mega-constellation in the sky.


On Sunday, it put up another 36 spacecraft, taking its total in-orbit network to 182.


But to provide internet connections around the globe, it will require, initially, 648.

INDIAN NAVY LAUNCHES OPERATION SAMUDRA SETU-II

The Indian Navy has again launched Operation Samudra Setu to help in faster transportation of medical oxygen and other requirements from other countries when the country is facing a severe shortage of oxygen to treat critical Covid-19 patients.

Indian Naval warships have been deployed to undertake shipment of liquid medical oxygen-filled cryogenic containers and associated medical equipment to support the nation’s fight against the Covid-19 pandemic.

Operation Samudra Setu was launched in May last year as part of the Vande Bharat Mission to bring nearly 4,000 Indians back home from countries like Maldives, Sri Lanka, and Iran amid the outbreak of coronavirus pandemic.

RAMSETU AND MODERN BRIDGE

The engineers who build the Railway track bridge over the great Salt Lake which connects East America and West America studied the building Technique of "Ram Setu" build by our ancient civil hydraulic engineers 'Nal' and 'Neel'.

When the U.S thought to expand the railways the biggest challenge was to connect East America and West America because of a giant sea-like lake between the two called "The Great Salt Lake". The challenge before the big engineers was to build a railway track across the lake. Then there was an engineer in the Union Pacific team who read "Ramayan" and he was well aware of "RamSetu". The engineer with his team traveled to India and studied Ramsetu.

Through study they realized unilateral track that is straight, the waves can break the track. The scientific reason behind it was, where the waves have more effect. There you get stability by Zig-Zag design.

EGYPTIAN MUMMY WAS A PREGNANT WOMAN

Warsaw, Apr 29 (AP): Polish researchers examined an ancient Egyptian mummy and they expected it to be a male priest. They were surprised when X-rays and computer tests revealed that it was a mummy of a woman who had been seven months pregnant.

Researchers said that "it is the world's first known case of such a well-preserved ancient mummy of a pregnant woman.'' The mummy arrived in Warsaw in 1826 and the inscription on the coffin was named a male priest. No examination until the current one had disproved the belief that it was a male. They estimated the woman was between 20 and 30 years old and said the size of the baby's skull suggested she was 26 to 28 weeks pregnant.

The findings and evidence of Warsaw Mummy Project tests and other mummies are at Warsaw's National Museum and they have published details this week in the Journal of Archaeological Science.

DRONES AGAINST CORONA

Sanitise containment zones as well as deliver medicine and essential goods to people affected by Covid-19 Karnataka chief minister BS Yediyurappa on Friday inaugurated an initiative to use drones.

"During these difficult times, it is very important to supply timely delivery of emergency medicines and Covid vaccines. I'm happy for the first time in the country drones are ready supplying medicines, and also for sanitizing public places in Bengaluru", CM Yediyurappa Said. The drones can carry 35-40 kg of materials. The Directorate General of Civil Aviation (DGCA) recently granted the Indian Council of Medical Research (ICMR) a conditional exemption for testing the feasibility of drones in delivering vaccines.

"Front line workers who transport Vaccines from one location to another could themselves be carriers of the virus," BBMP special commissioner Rajendran Cholan said.
