IN TWO DECADES JUNO HAS PROVIDED THE FIRST CLOSE-UPS OF JUPITER'S LARGEST MOON
Nasa released Juno spacecrafts' first two images on Tuesday, highlighting Ganymede's craters and long, narrow features possibly related to tectonic faults. One shows the moon's far side, opposite the sun.
"This is the closest any spacecraft has come to this mammoth moon in a generation," said Juno's lead scientist, Scott Bolton of the Southwest Research Institute in San Antonio.
E3 2021: UBISOFT MARIO RABBIDS SEQUEL OFFICIALLY ANNOUNCED; REVEALS INCREDIBLE NEW 2022 AVATAR GAME TRAILER
Much to gamers' relief, E3 2021 stuck to its announced date and time to kick off the mega event in style. The E3 2021 schedule is in the public domain and it has helped generate immense interest in the gaming community for all the entertainment in store. So far, new games like Unplugged and Wonderland have been announced and updates to Among Us have been revealed too. Now, Ubisoft has announced a Mario + Rabbids sequel coming next year, alongside a beautiful new game trailer for an Avatar game.
Game publisher Ubisoft on Saturday gave gamers a sneak peek at the company’s upcoming game Mario + Rabbids: Sparks of Hope for the Nintendo Switch that is expected to arrive next year, as reported by the Verge.
While Mario + Rabbids: Sparks of Hope has been announced four years after the original Mario + Rabbids: Kingdom Battle was first revealed, it remains to be seen whether the game will be as successful as the original title when it launches. As The Verge notes, Kingdom battle offered a tactical action game that was one of the “best early Nintendo Switch games” when it was launched.
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.

QUANTUM LEAP: THIS MICROSCOPE CAN ZOOM IN ON TINY STRUCTURES PREVIOUSLY NOT VISIBLE!
Australian researchers have found what could be referred to as a quantum leap in medical technology, a microscope that can view tiny biological structures that were not previously visible.
Scientists estimate that this new quantum medical technology can help in viewing the cells better and improve existing microscopes. It could further help in the improvement of medical imaging and technology.
This research was published in Nature. The newly developed microscope is a coherent Raman microscope that allows imaging of molecular bonds within cells with 35 percent more clarity.
The team was led by Caxtere A Cascio of the University of Queensland and tried to improve the capability of existing microscopes by increasing the light intensity that enhances biological imaging. Although this technology is still under development, it has outperformed conventional technologies.
The branch of quantum physics, quantum technology, is used to study the functions of tiny and subatomic particles. This branch has been used for five decades and can be used to enhance maritime and computing capabilities.
The researchers have tried to remove the problem of sound, as it interrupts resolution, sensitivity, and speed in conventional microscopes. While using bright lights seems the only way to remove noise. Still, it can’t be used while investigating living systems, “The bright lasers can severely disturb biological processes,” researchers said in the report.
“Our work will enable order-of-magnitude improvements in the signal-to-noise ratio and the imaging speed,” researchers concluded in the paper. This research is viewed as the next significant achievement after the 2014 Nobel prize-winning work by Eric Betzig, Stefan W Hell, and William E Moerner in chemistry. They were responsible for the development of super-resolved fluorescence microscopy.
70% OF THE SHARK POPULATION WAS WIPED OUT 19 MILLION YEARS AGO BY A 'MYSTERIOUS EVENT'
About 19 million years ago, a mysterious event wiped out about 70 percent of the world’s shark population, found a study published on June 4 in the journal Science. The extent of the shark die-off was twice the number of sharks killed when an asteroid had hit the earth 66 million years ago. The new study was published on June 4 in the journal Science. However, the scientists have no idea about what could be the cause of the shark population going almost extinct. “We happened upon this extinction almost by accident," said Elizabeth Sibert, the lead author of a study and a postdoctoral researcher at Yale’s Department of Earth and Planetary Sciences, in a news release by the Yale University.
According to Sibert, her team decided to build an 85-million-year long record of shark and fish populations. The scientists wanted to understand how the populations varied in the long term and that is when they found this mysterious drop-off. They found that the death toll for the sharks living in the open ocean was much higher compared to those who lived near coastal areas.
However, there is no big ecosystem disruption or climate calamity known at the time but the population of the sharks was drastically reduced.
According to Sibert, the interval is not known of any big changes in the earth’s history, “yet it completely transformed the nature of what it means to be a predator living in the open ocean."
Studying how this drastic extinction affected the remaining shark populations, and if they changed their habitat to avoid the open ocean, can help us understand how the decline in shark population can affect marine ecosystems. According to a study that was published in Nature in January, the shark population living in the open ocean has reduced by 70 percent over the past half-century. The reason for this decline is unsustainable overfishing. However, for the die-off that happened 19 million years ago, humans were not present on the earth.
MICROSOFT PLANS TO LAUNCH DEDICATED XBOX CLOUD GAMING HARDWARE
Microsoft will soon launch a dedicated device for game streaming, the company announced today. It’s also working with several TV manufacturers to build the Xbox experience right into their internet-connected screens and Microsoft plans to bring cloud gaming to the PC Xbox app later this year, too, with a focus on play-before-you-buy scenarios.
Microsoft didn’t provide any further details. But chances are we’re talking about either a Chromecast-like streaming stick or a small Apple TV-like box. So far, we also don’t know which TV manufacturers it will partner with.
In a few weeks, it’ll open cloud gaming in the browser on Edge, Chrome, and Safari, to all Xbox Game Pass Ultimate subscribers, it’s currently in limited beta And it is bringing Game Pass Ultimate to Australia, Brazil, Mexico, and Japan later this year, too.
In many ways, Microsoft is unbundling gaming from the hardware — similar to what Google is trying with Stadia an effort that, so far, has fallen flat for Google and Amazon with Luna. The major advantage Microsoft has here is a large library of popular games, something that’s mostly missing on competing services, except for Nvidia’s GeForce Now platform — though that one has a different business model since its focus is not on a subscription but on allowing you to play the games you buy in third-party stores like Steam or the Epic store.
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.
ACID RAIN IN SRI LANKA
There is a possibility of acid rain in the island nation as a result of the burning X-Press Pearl container ship in the waters of the Colombo Harbour. Sri Lanka's Marine Environment Protection Authority (MEPA) said acid.
When nitrogen oxide gas is emitted into the atmosphere will mix with water particles in the upper atmosphere to produce nitric acid for the acid rain.

APPLE EMPLOYEES RALLY AGAINST OFFICE WORKING PLAN
Apple employees have launched a campaign to push back against Tim Cook's plans for a widespread return to the office, according to reports.
It follows an all-staff memo last week in which the Apple boss said workers should be in the office at least three days a week by September.
But staff are demanding more flexibility, according to an internal letter obtained by news site The Verge. Apple's policy has "already forced some of our colleagues to quit", it said.
"Without the inclusivity that flexibility brings, many of us feel we have to choose between either a combination of our families, our wellbeing, and being empowered to do our best work, or being a part of Apple," the letter said.
"Over the last year we often felt not just unheard, but at times actively ignored," it also reads, accusing management of a "disconnect" with employees on the topic of remote or flexible working.
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.
JEFF BEZOS AND BROTHER TO FLY TO SPACE IN BLUE ORIGIN FLIGHT
The Amazon founder Jeff Bezos has said he will fly to space with his brother on the first human flight launched by his space company, Blue Origin.
In an Instagram post, Mr. Bezos said space flight was something he had wanted to do "all my life". Blue Origin is also auctioning off a seat in the capsule, for someone who will join the pair on the inaugural manned flight. Jeff Bezos is one of the world's richest people.
"On July 20th, I will take that journey with my brother," he wrote in the Instagram post. "The greatest adventure, with my best friend." Mr. Bezos's brother Mark called it a "remarkable opportunity" in the video.
Bidding for a seat on the New Shepard - the name of the Blue Origin vehicle - had reached $2.8m when Mr Bezos announced his plan to take the flight. The auction concludes on 12 June.
The New Shepard booster can land vertically on the ground after returning from space. It is named after Alan Shepard, the second person and first US citizen to fly into space.
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.

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.
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.
