Possible tectonic activity detected on the moon | Science & Tech News

Tectonic activity has been detected on the moon by researchers who have discovered a system of moving ridges topped with boulders on its near side.

“There’s this assumption that the moon is long dead, but we keep finding that that’s not the case,” said Professor Peter Schultz at Rhode Island’s Brown University.

“It appears that the moon may still be creaking and cracking – potentially in the present day – and we can see the evidence on these ridges,” explained Professor Schultz who co-authored a study published in the journal Geology.

The majority of the moon’s surface is covered by something called regolith, the powdery dust of rocks created by constant meteorite impacts.

Because the moon has no atmosphere to speak of, rocks and orbiting debris crash right into its surface and blow apart.

There are very few spaces on the lunar surface which aren’t covered by regolith – but some seemingly new spots have recently been discovered.

Adomas Valantinas, a graduate student at the University of Bern who was a visiting scholar at Brown, used data gathered by NASA’s Lunar Reconnaissance Orbiter (LRO) to spot these strange bare spots.

“Exposed blocks on the surface have a relatively short lifetime because the regolith buildup is happening constantly,” Mr Schultz said.

“So when we see them, there needs to be some explanation for how and why they were exposed in certain locations.”

“Just as concrete-covered cities on Earth retain more heat than the countryside, exposed bedrock and blocky surfaces on the moon stays warmer through the lunar night than regolith-covered surfaces,” the researchers said.

So using a tool on the LRO to measure the surface’s temperature, Mr Valantinas was able to discover more than 500 patches of exposed bedrock on narrow ridges following a pattern across the nearside of the moon.

Such ridges had been discovered before, but they were on the edges of very ancient lava-filled impact basins and could be explained by continued sagging in response to weight caused by the lava fill.

The new study found that these ridges are actually related to a mysterious system of tectonic features – ridges and faults – unrelated to the lava-filled basins.

“The distribution that we found here begs for a different explanation,” Professor Schultz said.

Mapping out all of these exposed ridges, Mr Valantinas and Prof Schultz discovered an interesting correlation between them and a previous NASA mission.

Back in 2014, NASA’s GRAIL mission discovered a network of ancient cracks in the moon’s crust, which became channels for magma from the moon’s core to flow to the surface.

This network lined up almost perfectly with the blocky ridges.

“It’s almost a one-to-one correlation,” Prof Schultz said. “That makes us think that what we’re seeing is an ongoing process driven by things happening in the moon’s interior.”

So the ridges, according to these scientists, are ancient magma flows which are still heaving upwards – breaking the surface and draining the regolith into cracks and voids, leaving the blocks exposed.

“Because bare spots on the moon get covered over fairly quickly, this cracking must be quite recent, possibly even ongoing today,” they say.

But what is causing this? According to the scientists, the tectonic movements may actually have begun billions of years ago with a giant impact on the far side of the moon.

Professor Schultz had previously proposed such an impact had formed the 1500-mile South Pole Aitken Basin, and shattered the interior on the opposite side of the moon – the side facing the Earth.

Magma from the core then filled these cracks and controlled the pattern detected in the GRAIL mission. The blocky ridges comprising this network now trace the continuing adjustments along these ancient weaknesses.

“This looks like the ridges responded to something that happened 4.3 billion years ago,” Prof Schultz said. “Giant impacts have long lasting effects.

“The moon has a long memory. What we’re seeing on the surface today is testimony to its long memory and secrets it still holds.”

Ramnaresh Sarwan denies Chris Gayle’s allegations on ouster from Jamaica Tallawahs, says ‘record must be set straight’- Firstcricket News, Firstpost

Former West Indies cricketer and Jamaica Tallawahs assistant coach Ramnaresh Sarwan has dismissed all the allegations levelled by Chris Gayle.

The big-hitting Gayle blamed Sarwan for an alleged fallout with Tallawahs, who did not retain him for the 2020 season. The opener claimed that Sarwan was behind his ouster and wanted to take control of the Caribbean Premier League (CPL) franchise.

“I categorically deny any involvement in the decision, or the decision-making process, which led to Gayle’s non-selection to represent the Jamaica Tallawahs in the 2020 Caribbean Premier League (CPL) Tournament,” Sarwan was quoted as saying by ESPNcricinfo on his Facebook page.

“In that video, he has levelled false allegations and tarnished the good name and reputation of a series of persons.

“I was the focus of most of the onslaughts. I reply, not because I feel that Gayle’s rantings are worthy of it, but because I feel that the public’s record must be set straight and also, to protect the character and careers of so many people, whose image he sought to besmirch,” he added.

In a video uploaded on his YouTube channel, Gayle had earlier referred to Sarwan as “a snake”.

Sarwan, in response, said that he respected Gayle but was utterly surprised by the Jamaican’s allegations.

“Let me make this abundantly clear that I played with Gayle since the inception of my career. I have always respected him as an extraordinary talent, a colleague and most importantly as a close friend. Hence, my utter shock at these allegations,” said Sarwan.

In a statement, Jamaica Tallawahs had also clarified that Sarwan had no role to play in Gayle’s ouster from the squad and added that the decision of not retaining Gayle for 2020 was based on “business and cricketing reasoning”.

Instagram is bringing new fonts to Stories - Latest News

Instagram is bringing new fonts to Stories – Latest News

Facebook-owned photo-sharing app Instagram is set to bring new fonts to its Stories. This was announced by the company on Twitter, where it said that it is testing it with a small percentage of people.

“New fonts coming to Stories soon*

*We’re testing this with a small percentage of people. Stay tuned for updates,” reads the tweet.

The company did not reveal the percentage or the location of users it is testing these or when the feature is coming to everyone else.

Recently, it was reported that Instagram is soon going to add a memorialisation option for the account of someone who has passed away. This was discovered by reverse-engineer Jane Manchun Wong.

Replying to her tweet, the account of Instagram’s PR team confirmed that this feature is indeed in the works. “Yes, we’re making changes to help people identify if an Instagram account belongs to someone who has passed away. We’ll have more to share on this at a later time,” reads the tweet.

Recently, Instagram rolled out the web support for sending Direct Messages (DMs) along with supports for viewing Instagram Live videos.

The live video streaming happens in the same portrait mode — and in the same size — as it does on users’ smartphones. However, thanks to the bigger screen space, you get to see the comments on the side of the ongoing live video instead of how you see them at the bottom on a smartphone on a transparent window making the viewing experience a little better on the web.

face shield: Varsity professor designs 'Face Shield' to counter coronavirus spread - Latest News

face shield: Varsity professor designs ‘Face Shield’ to counter coronavirus spread – Latest News

An assistant professor at the SRM University, Amaravati, has designed a Face Shield, using 3D printing technology, that will cover all the vital parts of the face and offers complete protection from coronavirus. “While manufacturing the Face Shield, 3D printing technology is used for designing a headband, upon which a 100 micron thick transparent plastic sheet is attached to ensure superior protection against the virus. It prevents air, dust, and liquids that are contaminated to come in contact with people. Also, there are no probable side effects on using the mask,” Panchagnula Jayaprakash, the designer, said.

Unlike the other face masks in regular use by all, including doctors, policemen and journalists, the Face Shield has no limitations and ensures full protection of the eyes, mouth and nose, which eliminates the risk of infection.

A release from SRM University on Friday said the Face Shield could be an effective alternative to the N95 mask that was found to cause facial irritation.

SRM University pro-chancellor Narayana Rao wrote to AP Deputy Chief Minister (Health) A K K Srinivas and Education Minister A Suresh explaining the features of the Face Shield, which could be a low-cost alternative.

“The Face Shield could be marketed for public use if the government approves it,” the release added.
