Egg-standing test goes viral as ring-of-fire eclipse crosses Asia – Cape Breton Post

KUALA LUMPUR (Reuters) – Can you make an egg stand on its narrow side during a solar eclipse?

According to a popular scientific theory, an egg will support itself that way when the moon obscures the sun and during the spring equinox, due to increased gravity.

While the theory has been debunked, that did not stop Malaysian and Indonesian social media users from putting it to the test on Thursday, as thousands of skywatchers gathered across parts of Asia to witness a rare annular solar eclipse.

Videos shared online showed dozens of users succeeding in getting eggs to balance on different surfaces including on gravel, a window pane, and a plate during the ‘ring-of-fire’ eclipse.

Hakeem Maarof, a Malaysian father of two, filmed eggs standing on end on a stone pavement and on the road after remembering being told about the theory by a friend.

“It’s more of an experiment for my kids,” Hakeem, who posted the footage of Facebook, told Reuters.

Dr Chong Hon Yew, a retired physicist from the Malaysian Science University, said there was no evidence to back up the theory.

“You can do the same experiment tomorrow, before or after eclipse – it’s easy to do it,” Chong said. “But it’s a fun trick to do (during an eclipse) to get young kids interested in science and astronomy.”

Thursday’s annular eclipse – which occurs when the moon covers the sun’s center but leaves its outer edges visible to form a ring – was also visible in Saudi Arabia, Singapore, India and Sri Lanka.

In most years, two solar eclipses are visible from somewhere on Earth. The maximum number per year is five.

SpaceX expands public beta test of Starlink satellite internet to Canada and the UK – CNBC

SpaceX has launched more than 1,000 of its Starlink high-speed internet satellites to date and, as it seeks regulatory approval in other countries, Elon Musk’s company is now offering early public access to the service in Canada and the U.K.

“Earlier this month we expanded our ‘Better than Nothing Beta’ program to include customers across the pond in the United Kingdom,” SpaceX lead manufacturing engineer Jessie Anderson said during the company’s launch webcast on Wednesday.

“Within the northern U.S. and Canada, and now the U.K., we are focused on rural and remote areas where there is no easy access to fiber or cable,” Anderson added.

SpaceX began the public beta program in October, with service priced at $99 a month, in addition to a $499 upfront cost to order the Starlink Kit, which includes a user terminal and Wi-Fi router to connect to the satellites.

Starlink is SpaceX’s plan to build an interconnected internet network with thousands of satellites, designed to deliver high-speed internet to anywhere on the planet. 

The network is an ambitious endeavor, which SpaceX has said will cost about $10 billion or more to build. But the company’s leadership estimates that Starlink could bring in as much as $30 billion a year, or more than 10 times the annual revenue of its rocket business.

SpaceX launched its 17th Starlink mission from Florida on Wednesday morning, with a Falcon 9 rocket carrying another batch of 60 satellites to orbit.

The launch also marked a milestone for SpaceX’s reuse of its rockets, with the Falcon 9 booster launching and landing for a record eighth time. Musk has previously said that SpaceX’s Falcon 9 rockets are designed to launch and land up to 10 times without major repairs or refurbishment.

Anderson noted that, in addition to individuals in rural areas of the northern U.S., SpaceX has signed up the town of Marysville, Ohio, and Virginia’s Wise County Public School District for Starlink service.

In the Ontario province of Canada, the rural indigenous community of Pikangikum First Nation became the first in the country to receive Starlink service.

Pikangikum is about 300 kilometers northeast of Winnipeg and has a population of less than 3,000 people, with about 400 to 500 households. SpaceX partnered with Canadian information and technology services company FSET to bring Starlink user terminals to the Pikangikum community.

“I hope that this gives them, the younger generations, a little bit of hope,” Pikangikum Health Authority victim services leader Vernon Kejick said in a video on SpaceX’s launch webcast. “We’re creating a pathway for the younger people.”

The Starlink kits were delivered via airplane, which is the main way the community connects with more populated areas of Canada.

“There’s still a lot of work to do, but at least we have access to technology and information, and hopefully that playing field is at least a little closer to being level,” FSET CEO Dave Brown said on the launch webcast on Wednesday.

Starlink recently received approval to begin operating in the U.K., where it is priced at £89 per month plus the £439 cost of the kit. It’s unclear how many homes and offices are currently using Starlink’s service.

SpaceX continues to look to expand Starlink internationally, with public records showing the company registered in Austria, Australia, Argentina, Brazil, France, Chile, Colombia, Germany, Greece, Ireland, Italy, Mexico, the Netherlands, New Zealand, the Philippines, South Africa and Spain.

The company also requested market access in Japan, and Musk has talked about Starlink coming to India and the Caribbean as well.

Scientists Take a Mighty Close Look at a Dinosaur's Butthole For the First Time Ever – Interesting Engineering

Published

 on


Scientists have a pretty good idea about what dinosaurs looked like, they can deduce things like if they were scaly, feathered, or horned for example. But what they haven’t had a chance to discover and describe in much detail are these prehistoric creatures’ backsides. Yes, we mean buttholes. 

But these aren’t mere buttholes, these are cloacae, or vents, that have been pleasantly described as the “Swiss Army knife of buttholes,” by Science Alert. Used for breeding, defecating, and urinating, these vents are found in vertebrates and are truly multi-purposed. 

Scientists from the University of Bristol managed to get a close look and describe for the first time ever what a Psittacosaurus dino’s cloaca looked like, publishing their findings in Current Biology on Tuesday.

Thanks to these scientists, we now have a detailed description of a non-avian dinosaur’s cloaca. Even though some animals today, such as birds, amphibians, reptiles, and some mammals have cloacae, very little was yet known about dinosaur cloacae — up until now. 

I noticed the cloaca several years ago after we had reconstructed the color patterns of this dinosaur using a remarkable fossil on display at the Senckenberg Museum in Germany which clearly preserves its skin and color patterns,” explained palaeobiologist Jakob Vinther of the University of Bristol.

So Vinther and his team decided to compare the fossilized cloaca to modern-day ones. The team could only gather information about the exterior of the fossilized cloaca, as the interior was not properly preserved. 

Dr. Diane Kelly, an expert on vertebrate penises and copulatory systems from the University of Massachusetts Amherst, also working on the study said, “Indeed, they are pretty non-descript. We found the vent does look different in many different groups of tetrapods, but in most cases, it doesn’t tell you much about an animal’s sex.”

Regardless, the exterior of the cloaca could provide decent information about what the dinosaur’s “vent” looked like, and how it was used. The team found out the dino cloaca was different from those of living creatures, however, it shares similarities with those of crocodilian reptiles, like alligators and crocodiles.

One interesting facet the researchers noticed was the dino’s cloaca’s outer margins were highly pigmented with melanin, which means it may have been used as a signaling system, similar to baboons today. 

As Robert Nicholls, a colleague working on the study and a paleoartist, said “Knowing that at least some dinosaurs were signaling to each other gives palaeoartists exciting freedom to speculate on a whole variety of now plausible interactions during dinosaur courtship. It is a game-changer!”

Paloma Faith subject of ‘exposing’ BBC documentary about juggling work and motherhood

Paloma Faith will be the subject of an “exposing” BBC documentary about juggling her career with motherhood. The one-hour film Paloma Faith – As I Am will follow the singer, who has spoken openly about her experiences with IVF, over a year of her life as she balances motherhood and her career, navigating the demands of a make-or-break tour with writing a new album, launching an acting career and being a parent. The London-born singer, 39, welcomed her first child with her long-term boyfriend, the French artist Leyman Lahcine, in December 2016 although they initially decided not to reveal the child’s gender in a bid to maintain their privacy.
