Ontario, Canada, June 16: Daredevil Nik Wallenda became the first person to walk on a tightrope across the Niagara Falls, taking steady, measured steps Friday night for 1,800 feet across the mist-fogged brink of the roaring falls separating the U.S. and Canada.

"I feel like I'm on cloud nine right now," an exuberant Wallenda told reporters after accomplishing what he said was his childhood dream before an estimated 112,000 people crowding the shores of both countries and millions more who watched a live television broadcast.

He described wind "coming from every which way," mist so powerful he had to blink it away to maintain his vision and a breathtaking view during the nighttime walk illuminated by spotlights that "compared to nothing."

"There was no way to focus on the movement of the cable," said Wallenda, 33. "If I looked down at the cable there was water moving everywhere. And if I looked up there was heavy mist blowing in front of my face. So it was a very unique, a weird sensation."

He said he accomplished the feat through "a lot of praying, that's for sure. But, you know, it's all about the concentration, the focus, and the training."

The seventh-generation member of the famed Flying Wallendas had long dreamed of pulling off the stunt, never before attempted. Other daredevils have wire-walked over the Niagara River but farther downstream and not since 1896.


"This is what dreams are made of, people," said Wallenda, who wore a microphone for the broadcast, shortly after he stepped off from a platform on the American shore.

Along the way, he calmly prayed aloud.

After passing the halfway mark, Wallenda expressed fatigue. "I'm strained, I'm drained," he said. "This is so physical, not only mental but physical."

Toward the end, as he neared the Canadian shore, Wallenda dropped to one knee and pumped his fist while the spectators cheered.


He broke into a playful run about 15 feet from the finish line, where his wife and three children waited.

"I am so blessed," he said later. "How blessed I am to have the life that I have."

ABC televised the walk and insisted Wallenda use a tether to keep him from falling in the river. Wallenda said he agreed because he wasn't willing to lose the chance to perform the walk it took him well over a year to win permission from two countries to do. Such stunts are normally illegal. ABC's sponsorship helped offset some of the $1.3 million cost of the spectacle.

Wallenda said he thought about the tether, which was secured at his waist and dragged behind him, at several points along the 30-minute walk but wasn't hindered by it as he'd feared.

"Awesome! The whole thing is awesome," 8-year-old William Clements of Dresden, Ontario, said after watching the walk with his family from the Canadian side, adding he wouldn't want to walk "even over something not high."

"He was meant to do it. The weather was perfect," said Glenda Rutherford of Ontario. "It was amazing."

For Wallenda, who has grown up on the high wire and holds six Guinness records for various stunts, the Niagara Falls walk was unlike anything he'd ever done. Because it was over water, the 2-inch wire didn't have the usual stabilizer cables to keep it from swinging. Pendulum anchors were designed to keep it from twisting under the elkskin-soled shoes designed by his mother.

The Wallendas trace their roots to 1780 Austria-Hungary, when ancestors traveled as a band of acrobats, aerialists, jugglers, animal trainers and trapeze artists. The clan has been touched by tragedy, notably in 1978 when patriarch Karl Wallenda, Nik's great-grandfather, fell to his death during a stunt in Puerto Rico.

Wallenda said that at one point in the middle of the walk, he thought about his great-grandfather and the walks he had taken:


"That's what this is all about, paying tribute to my ancestors, and my hero, Karl Wallenda."

About a dozen other tightrope artists have crossed the Niagara Gorge downstream, dating to Jean Francois Gravelet, aka The Great Blondin, in 1859. But no one had walked directly over the falls, and authorities hadn't allowed any tightrope acts in the area since 1896. It took Wallenda two years to persuade U.S. and Canadian authorities to allow it, and many civic leaders hoped to use the publicity to jumpstart the region's struggling economy, particularly on the U.S. side of the falls.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Seoul, May 2: North Korean leader Kim Jong Un has made his first public appearance since speculation about his health began last month, cutting the ribbon at the opening of a fertilizer factory, KCNA reported Saturday.
 
Kim attended the event on Friday in Sunchon, near the capital Pyongyang, after nearly three weeks of swirling rumours that the leader of the nuclear-armed nation was seriously ill or possibly dead.
 
The North Korean leader had not made a public appearance since presiding over a Workers' Party politburo meeting on April 11, and the following day state media reported that he had inspected fighter jets.
 
At Friday's event, "all the participants broke into thunderous cheers of 'hurrah!'" when Kim appeared, the Korean Central news agency reported.
 
He inspected the facility and was "briefed about the production processes," the report said.
 
Kim "said with deep emotion" that his grandfather Kim Il Sung and father Kim Jong Il "would be greatly pleased if they heard the news that the modern phosphatic fertilizer factory has been built," it added.
 
Also in attendance were other senior officials, including his sister and close adviser, Kim Yo Jong. Photos from the ceremony were not immediately released.
 
Conjecture over Kim's health had grown since his conspicuous no-show at April 15 celebrations for the birthday of his grandfather, the North's founder -- the most important day in the country's political calendar.
 
His absence unleashed a series of unconfirmed reports over his condition, triggering global fears over the North's nuclear arsenal -- and who would succeed Kim were he unable to lead.
 
A top security advisor to South Korea's President Moon Jae-in said less than a week ago that Kim was "alive and well," downplaying rumors that he was ill or incapacitated.
 
The advisor, Moon Chung-in, told CNN that Kim had been staying in Wonsan -- a resort town in the east of North Korea -- since April 13, adding: "No suspicious movements have so far been detected."
 
South Korea Reports Kim Jong Un Is 'Alive and Well' Amid Rumours of His Death
 
South Korea has told CNN that the rumours of North Korean leader Kim Jong Un's death are untrue.
 
Rumours of ill health
 
Daily NK, an online media outlet run mostly by North Korean defectors, reported that Kim was undergoing treatment after a cardiovascular procedure last month.
 
Citing an unidentified source inside the country, it said Kim -- who is in his mid-30s -- had needed urgent treatment due to heavy smoking, obesity and fatigue.
 
Soon afterwards, CNN reported that Washington was "monitoring intelligence" that Kim was in "grave danger" after undergoing surgery, quoting an anonymous US official.
 
US President Donald Trump appeared to confirm that Kim was alive earlier this week.
 
On Friday, Trump refused to comment on Kim's reported re-emergence.
 
Previous absences from the public eye on Kim's part have prompted speculation about his health.
 
The North is extremely secretive, and doubly so about its leadership.
 
Kim's father and predecessor had been dead for two days before anyone outside the innermost circles of North Korean leadership was any the wiser.
 
In 2014, Kim Jong Un dropped out of sight for nearly six weeks before reappearing with a cane.
 
Days later, the South's spy agency said he had undergone surgery to remove a cyst from his ankle.

Washington, Jun 2: There is no place for hate and racism in the society, Microsoft CEO Satya Nadella has said, asserting that empathy and shared understanding are a start, but more needs to be done. Nadella’s remarks come in the wake of the custodial death of George Floyd, a 46-year-old African-American man who was pinned to the ground in Minneapolis on May 25 by a white police officer who kneeled on his neck as he gasped for breath.

“There is no place for hate and racism in our society. Empathy and shared understanding are a start, but we must do more,” Nadella said in a tweet on Monday.

“I stand with the Black and African American community and we are committed to building on this work in our company and in our communities,” Nadella said.

A day earlier, Google CEO Sunder Pichai expressed solidarity with the African-American community.

“Today on US Google & YouTube homepages we share our support for racial equality in solidarity with the Black community and in memory of George Floyd, Breonna Taylor, Ahmaud Arbery & others who don’t have a voice,” Pichai wrote on Twitter on Sunday.

“For those feeling grief, anger, sadness & fear, you are not alone,” Pichai said, sharing a screenshot of the Google search home page which said, “We stand in support of racial equality, and all those who search for it.”

Nadella’s Microsoft also said they will be using the platform to amplify voices from the Black and African American community at the company.

Nadella had also spoken out a few months ago about the discriminatory Citizenship Amendment Act passed in his native country. Talking to BuzzFeed’s editor-in-chief, Ben Smith, in Manhattan, Nadella said what’s happening in the country is “sad.”

“I think what is happening is sad. I feel, and in fact quite frankly, now being informed (and) shaped by the two amazing American things that I’ve observed which is both, it’s technology reaching me where I was growing up and its immigration policy and even a story like mine being possible in a country like this.

“I think, it’s just bad, if anything, I would love to see a Bangladeshi immigrant who comes to India and creates the next unicorn in India or becomes the CEO of Infosys. That should be the aspiration. If I had to sort of mirror what happened to me in the US, I hope that’s what happens in India,” Microsoft’s India-born CEO was quoted as saying by BuzzFeed.
