As in this period of COVID- 19 virus demonstrate, beginning since at least 2 months ago, people around worldwide,

fail into trouble every day. And especially we don't know how far it will be the last, meanwhile the amount of the infected

patients plus more and more into advancement.

The furiously of it comes to whom with don't know when. Very, very worsen at all.

Many thanks to my assistant, G Grammarly as ever.

New Evidence Found of Ancient Rivers on Mars

Scientists say they have found the most detailed evidence yet of long-flowing, ancient rivers on Mars.

The discovery supports existing evidence that Mars – which today is dry and cold – was once a water-rich planet. The researchers say their findings suggest rivers may have flowed on the surface of Mars for hundreds of thousands of years.

The evidence came from new satellite pictures of the Martian surface. These images were captured by a camera on NASA’s Mars Reconnaissance Orbiter. The camera is able to take detailed pictures of the surface while orbiting the planet from about 400 kilometers away.

A team of scientists studied the images, which showed a rocky area within the planet’s Hellas Impact Crater. An impact crater is formed when a space object crashes into a planet or moon. The Hellas Impact Crater, in the southern Martian hemisphere, is one of the largest formations of its kind in the solar system.

The team was led by Francesco Salese, a geologist at Utrecht University in the Netherlands. The research results were recently published in a study in Nature Communications.

Salese said the scientists studied sedimentary rocks from a 200 meter high rocky cliff. Sedimentary rocks form when sediment, transported by water or wind, settles and forms solid rock.

“These are sedimentary rocks, 3.7 billion years old, and were formed by rivers that were likely active for over 100,000 years of Martian history,” Salese said in a statement.

“OK, it is not like reading a newspaper, but the extremely high resolution imagery allowed us to ‘read’ the rocks as if you are standing very close to the cliff,” he added.

Salese said even without the ability to examine the cliff area up-close on Mars, the pictures show strong similarities to sedimentary rocks found on Earth.

The researchers created three-dimensional, or 3D, images of the area to get a more detailed understanding of it. The pictures suggested that some ancient Martian rivers were several meters deep.

William McMahon is another geologist who was part of the investigation team. He said sedimentary rocks have long been studied on Earth to learn what conditions were like on our planet millions, or even billions of years ago.

“Now we have the technology to extend this methodology to another terrestrial planet, Mars, which hosts an ancient sedimentary rock record which extends even further back in time than our own,” McMahon said in a statement.

Another leader of the team was Joel Davis, a researcher with Britain’s Natural History Museum. He said scientists had never before been able to examine such a rock formation with such great detail.

Davis said the discovery is “one more piece of the puzzle in the search for ancient life on Mars.” He added that it also provides new evidence of how much water existed on Mars in ancient times.

“The rivers that formed these rocks weren't just a one-off event - they were probably active for tens to hundreds of thousands of years,” Davis said.

Salese added that the findings show Mars had an environment able to support large, flowing rivers for extended periods of time.

“This kind of evidence, of a long-lived watery landscape, is crucial in our search for ancient life on the planet,” Salese said.

What Do Studies on New Coronavirus Mutations Tell Us?

May 17, 2020

Studies of genetic material from thousands of samples of the novel coronavirus show that it is changing. Experts say those findings might affect the current pandemic and efforts to develop vaccines and treatments.

The GISAID Initiative is a partnership between a not-for-profit group and the governments of Germany, Singapore, and the United States. The initiative was formerly called the Global Initiative on Sharing All Influenza Data. It collects records of genetic information on influenza viruses and releases them to the public.

Researchers in the United States used GISAID data to follow genetic changes, or mutations, in the “spike” of the new coronavirus. The spike is the part of the coronavirus that gives it its unusual shape.

The researchers said they discovered 14 such mutations early in their investigation at the Los Alamos National Laboratory. They noted that one, called D614G, was “of urgent concern” because it may make the disease more infectious.

Using the same GISAID records, a team in Britain studied genetic material from more than 7,500 virus samples from infected patients around the world.

The team is from University College London. They reported finding 198 mutations in the coronavirus genomes they examined, but none appeared to be of special concern.

Scientists at Britain’s Glasgow University also studied mutations in the samples of the genomes. But they found these changes did not confirm the existence of different strains of the virus.

That finding disproved an earlier study by Chinese researchers. Their study suggested there had been two strains in patients at the start of the COVID-19 outbreak in China. One of the strains had been noted as more “aggressive,” the researchers said.

Eric Topol is a heart specialist and geneticist. He established the Scripps Research Translational Institute in La Jolla, California. He told the Reuters news agency the idea that there are several strains of the virus must be rejected.

“We know there is only one strain,” Topol said.

Jonathan Stoye is head of virology at Britain’s Francis Crick Institute. He said that taken together, the studies offer an interesting look at the coronavirus, and show that it is “a moving target.”

“The virus is evolving and is changing. And we don’t yet know what the consequences of those changes are,” Stoye said.

“This coronavirus mutates just like any good RNA virus should,” added Mark Schleiss, a molecular genetics expert. He is with the University of Minnesota Medical School.

Genetics and biology experts say it is still too early to know whether any of the mutations are meaningful.

Lawrence Young is a professor of molecular oncology at the University of Warwick in Britain. He said that while there have been many predictions about the rise of more aggressive strains, studies so far show that is not the case.

Eric Topol noted scientists will have to examine exactly how a given genetic mutation affects the behavior of the virus to find out more.

Transcript 

Note: This is not a word for word transcript    

Neil
Hello. This is 6 Minute English. I'm Neil.

Sam
And I'm Sam.

Neil
Sam, have you considered the future of food much?

Sam
Well I think in the future I might have a sandwich – in about 30 minutes in the future.

Neil
Not quite what I meant! With the population of the world increasing along with the negative effects of climate change and other global issues, we might have to radically change our diets in the future.

Sam
Ah, yes I have heard about this – there are all sorts of developments from growing artificial meat to developing insect-based foods.

Neil
Mmm, tasty. Well we’ll look a little more at this topic shortly, but we start, as ever, with a question and it’s a food-based question. In which continent did tomatoes originate? Is it…

A: South America

B: Africa

C: Asia

What do you think, Sam?

Sam 
No idea. I’m going to say Africa, but that’s just a guess.

Neil
OK. Well I will reveal the answer later in the programme. On a recent edition of BBC Radio 4’s The Food Programme there was an interview with Dr Morgaine Gaye. She is a futurologist. A futurologist is someone who studies and predicts the way we will be living in the future. Her particular area of expertise is the subject of food. What two things does she say she thinks about?

Dr Morgaine Gaye
As a food futurologist, I think about not just what we’re going to be eating in the future but why. Why that thing, why that trend, why will people suddenly latch onto that food, that way of eating that food at that particular time? And when I work for large companies, that’s what they want to know. There is an element of a hunch. And then proving or disproving that hunch.

Neil
So, what two things does she think about?

Sam
She says that as a food futurologist she thinks about what we will be eating in the future and also why we will be eating that food.

Neil
Yes, in particular she looks at why there are particular trends. A trend is what is popular now or what is becoming popular. For example, at the moment there is a trend for eating less red meat.

Sam
She also looks at why people latch onto particular trends. To latch onto here means to be very interested in something. So if you latch onto a particular food trend, you start to follow that trend, you might start eating that particular diet.

Neil
Information about future trends is very important for companies in the food business. How does she actually predict these trends?

Sam
She says she starts with a hunch. A hunch is a feeling you get that something is true. You don’t have any real evidence, but your experience and knowledge makes you think you might be right.

Neil
Let’s listen again.

Dr Morgaine Gaye
As a food futurologist I think about not just what we’re going to be eating in the future but why. Why that thing, why that trend why will people suddenly latch onto that food, that way of eating that food at that particular time? And when I work for large companies, that’s what they want to know. There is an  element of a hunch. And then proving or disproving that hunch.

Neil
Dr Gaye goes on to talk about how on the subject of food, there are restrictions. Why is that?

Dr Morgaine Gaye
Food business of course has different restrictions around it because it’s about safety, we’re ingesting that. The supply chain and the labelling laws are very stringent especially in this country so it takes longer to get an ide­a from just a concept that’s discussed around a table to an actual production facility, labelled, branded, tested, marketed and put on the shelves.

Neil
So, why restrictions?

Sam
Well, it’s about safety. Because we are ingesting food, which is a way of saying we are putting it into our bodies, it has to be safe.

Neil
It can be a long process of developing a new food and getting it into the shops because of the need to be safe and meet the laws of different countries. In the UK she mentions that the food safety laws are very stringent. This means that the laws are very tough, very strict. Let’s hear Dr Gaye again.

Dr Morgaine Gaye
Food business of course has different restrictions around it because it’s about safety, we’re ingesting that, the supply chain and the labelling laws are very stringent especially in this country so it takes longer to get an ide­a from just a concept that’s discussed around a table to an actual production facility, labelled, branded, tested, marketed and put on the shelves.

Neil
Right, well before we review our vocabulary, let’s get the answer to the question. In which continent did tomatoes originate? Is it…

A: South America

B: Africa

C: Asia

Sam, what did you say?

Sam
I made a guess at Africa.

Neil
Well, I’m afraid that’s not right. Congratulations though to everyone who said South America. Right, let’s recap today’s words and expressions.

Sam
OK, well we started with the word futurologist. This is a noun to describe someone who studies and predicts the way we will be living in the future.

Neil
Then we had trend. This word can describe what is popular now and the way in which what is popular is changing. For example now we are seeing a trend for eating less red meat in some parts of the world.

Sam
If you latch onto something, you become interested in it and associate yourself with it – we heard that people very quickly latch onto food trends

Neil
Then there was hunch. A hunch is a feeling about something you think might be true even though you don’t have real evidence for it. Ingesting something means taking it into your body, so eating or drinking it.

Sam
And finally a stringent rule is a very strict rule, a tough rule or law which in connection to food is designed to make sure it is safe and of a suitable quality.

Neil
OK, thank you, Sam. That’s all from 6 Minute English. Goodbye!

Sam
Bye!

PTT to raise Bt44 billion through bonds for debt refinancing and augmenting liquidity

May 18. 2020

Facebook Twitter

By The Nation

Energy conglomerate PTT plans to issue corporate bonds worth Bt44 billion this year and next year, in order to refinance its debt and increase liquidity, PTT chief financial officer Pannalin Mahawongtikul said. 

Debentures worth Bt 27 billion will reach maturity over the next two years -- Bt1 billion this month, Bt1 billion more in July, Bt22 billion in September and about Bt15 billion more next year, she said.

Due to the Covid-19 fallout, some of PTT's debtors, like airlines and those in the gas industry, have delayed their debt payments, she said. However, the delay in payments by clients has not adversely affected PTT's cash flow, she reassured.

The company currently holds Bt50 billion cash despite its reported net loss of Bt1.6 billion in the first quarter. The losses stem from oil stock loss (cost of oil stockpile) , foreign currency borrowings and weakening of the baht.

PTT Group has losses from oil stock if Bt70 billion from business operations in the first quarter worth Bt17 billion. 

The company is optimistic about the outlook for the rest of the year; refinery margins are likely to rise with crude oil price estimated at between $30 to $40 per barrel. The group’s chemical products, however, are under pressure as new suppliers from China have entered the market.
