Scientists store entire human genome on ‘memory crystal’ that could survive billions of years

Scientists in the United Kingdom have stored the entire human genome on a “5D memory crystal,” in the hope that it could be used in the future as a blueprint to bring humanity back from extinction.

The crystal, which was developed by a team of researchers at the University of Southampton’s Optoelectronics Research Centre, could also be used to create a record of plant and animal species faced with extinction.

It can hold up to 360 terabytes of information for billions of years and can withstand extreme conditions, including freezing, fires, direct impact force, cosmic radiation and temperatures of up to 1,000 degrees Celsius, the university said in a press statement published Thursday.

In 2014, the crystal was awarded the Guinness World Record for “most durable digital storage material.” Kazansky’s team used ultra-fast lasers to inscribe the human genome data into voids as small as 20 nanometers (a nanometer is about one-billionth of a meter).

They describe the data storage on the crystal as 5D because the information is translated into five different dimensions of its nanostructures — their height, length, width, orientation and position.

“The 5D memory crystal opens up possibilities for other researchers to build an everlasting repository of genomic information from which complex organisms like plants and animals might be restored should science in the future allow,” said Peter Kazansky, a professor of optoelectronics, who led the team at Southampton.

The team had to consider who – or what – would retrieve the information, so far off into the future.

It could be an intelligence (species or machine) – or it could be found in a future so distant that no frame of reference would exist for it. To help whoever finds it, the researchers included a visual key.

“The visual key inscribed on the crystal gives the finder knowledge of what data is stored inside and how it could be used,” said Kazansky.

“Their work is super impressive,” said Thomas Heinis, who leads research on DNA storage at Imperial College London and was not involved in the study. However, he says questions remain about how such data could be read in the future.

“What Southampton presents probably has a higher durability, however, this begs the question: what for? Future generations? Sure, but how will they know how to read the crystal? How will they know how to build the device to read the crystal? Will the device be available in hundreds of years?” he added. “I can barely connect my 10-year-old iPod and listen to what I listened back then.”

For now, the crystal is stored in the Memory of Mankind archive, a time capsule within a salt cave in Austria.

In 2018, Kazansky and his team used the memory crystal technology to store Isaac Asimov’s “Foundation” trilogy of science fiction books, which were then launched into space aboard a Tesla Roadster. The technology has also been used to store major documents from human history, including the Universal

Declaration of Human Rights and the Magna Carta. Earlier this year, scientists revealed a plan to safeguard Earth’s species in a cryogenic biorepository on the moon, intended to save species in the event of a disaster on our home planet.

A new report into world education shows Finland has the best system. The global study is called "The Learning Curve" and is from the British magazine "The Economist". It aims to help governments provide a better education to students. The 52-page report looked at the education system in 50 countries. Researchers analysed millions of statistics on exam grades, literacy rates, attendance, and university graduation rates. Asia did well in the report, with South Korea, Hong Kong, Japan and Singapore finishing second, third, fourth and fifth. The United States came 17th in the study, while Mexico, Brazil and Indonesia filled the bottom three positions in the top 50. 

The Learning Curve reported on five things that education leaders should remember. The first is that spending lots of money on schools and teachers does not always mean students will learn. Second is that "good teachers are essential to high-quality education". The report said teachers should be "treated as the valuable professionals they are, not as technicians in a huge, educational machine". Numbers three and four are that a country's culture must have a strong focus on the importance of education, and parents have a key part to play. Finally, countries need to "educate for the future, not just the present." The report said: "Many of today's job titles…simply did not exist 20 years ago."

Village’s Amateur Archaeologists Find Lost Tudor Palace

1. When a group of amateur archaeologists set out to find the buried remains of a Tudor palace
2. in their Northamptonshire village five years ago, they knew the odds were against them. “Many
3. of us were brought up in the village, and you hear about this lost palace, and wonder whether
4. it’s a myth or real. So we just wanted to find it”, said Chris Close, the chair of the Collyweston
5. Historical and Preservation Society (Chaps) which made the discovery of the Palace of
6. Collyweston in a back garden this year. “But we’re a bunch of amateurs. We had no money, no
7. expertise, no plans, no artist impressions to go off, and nothing remaining of the palace. It was
8. naivety and just hard work that has led us to it”.
9. The site was found using geophysical surveys and ground-penetrating radar. Various
10. attempts had been made in the 1980s and 90s to find Collyweston Palace, the home of Henry
11. VII’s mother, Lady Margaret Beaufort. However, without the advantage of modern technology,
12. none had succeeded. The palace was famous during the 15th century and several historic events
13. took place there. The pre-wedding celebrations of Margaret Tudor to James IV of Scotland in
14. 1503 took place in the palace, and Henry VIII is recorded as holding court there on 16 and 17
15. October 1541. By the mid-17th century, it had fallen into disrepair, and until the Chaps dig
16. uncovered the palace walls in March, there was very little remaining evidence of its existence.
17. “A number of things have only really come to light as we’ve done this project”, said Close.
18. “As you do more and more research, and various different records start to become unearthed,
19. we realized Collyweston had privy councils being run from here, which is of massive national
20. importance”. Historians from the University of York helped verify the group’s findings and identify
21. the palace through some uncovered stone moldings, and will work with Chaps on more
22. excavations to further reveal the structure and conserve it for the future.
23. The Chaps team, which comprises more than 80 members ranging from teenagers to people
24. in their 70s and 80s, first set out their plan to find the palace in March 2018, using “local folktales
25. and hearsay” to help refine their search area. They carried out geophysical surveys and used
26. ground-penetrating radar (GPR) to help reveal the location of the palace walls, before securing
27. permission from homeowners to excavate in gardens. “We’ve done it all on an absolute
28. shoestring”, said Close. “We’ve basically done an £80,000-£90,000 project for roughly £13,000.
29. For us, being a little society, to have achieved this with no money, or expertise, or plans, I think
30. it’s something that the whole society should be proud of”.

Valdivia Figurines and the appeal of 'the oldest'

(1º§) The logo for the Ecuadorian Ministry of Culture website is about my favourite thing of the afternoon which is saying a lot since I spent much of the day reading about giant Olmec heads. Three Valdivia Figurines in the colours of the Ecuadorian flag? I am sold! Golly, I love Valdivia figurines for all the right and all the wrong reasons.

(2º§) There are two things that can easily be said about Valdivia figurines: they are VERY Ecuadorian and they are VERY looted. The first explains why they appear prominently on the Ministry of Culture website (and on stencilled graffiti around Quito circa 2007). Ancient Ecuador has played second fiddle to Ancient Peru since the early days of archaeology. The Valdivia culture, however, represents something that Peru doesn't have, 'the oldest'. Everyone loves 'the oldest', national pride, etc. etc.

(3º§) Who else loves 'the oldest'? Collectors and Museums. If the Valdivia pottery sequence is the oldest in the new world, collectors want a slice of that pie. Heck, even better than some junky pottery, the Valdivia made interesting figurines: lovely ladies that look good on stark black backgrounds in auction catalogues. They are part of 'the oldest' yet they also look good.

(4º§) Valdivia sites are famously looted and Valdivia figurines are famously faked. A few years back I started doing some initial work into looting in Ecuador (which led to fieldwork in Quito and the cloud forest that didn't really go anywhere as of yet) and I, like anyone else going down that road, came across Bruhns and Hammond's 1983 Journal of Field Archaeology piece 'A Visit to Valdivia'. Knowing nothing at all about Ecuador at the time, I had never heard of Valdivia, a wonder since the only Ecuadorian archaeology books that Cambridge owns are a few by the late Betty Meggars and Emilio Estrada from the 1950s and 1960s which link uber-ancient Ecuador to Jomon Period Japan (yeah...I know). As Bruhns and Hammond relate, Meggars detected faking at Valdivia immediately after the start of her excavations: practical jokers who discovered a market for their copies. As the market for the pieces grew, the presumed fakes get more and more elaborate and fanciful...and Valdivia sites were just looted to pieces.

(5º§) So really with Valdivia we are left with a situation where we don't know what is real. It is directly comparable to the Cycladic Figurine problem: the corpus is mostly looted, it contains tons of forms not found in the limited archaeological excavations that have been conducted, and we intellectual consumers of artefacts don't know what to believe. To me Valdivia figurines are the perfect looting Catch 22: they warrant study so that the interested public can learn about 'the oldest', but they can't be studied because collectors wanted 'the oldest' so sites were looted and buckets of fakes were produced.

(6º§) In 2007 I bought a fake Valdivia figurine in Otavalo which now stands in a Spondylus shell on my counter and watches me cook. The fella selling it to me told me it was real. I knew it wasn't but made to put it back saying something along the lines that law breaking makes me sick. He quickly agreed that it wasn't real and cut his asking price by a ton. Que Sera. Three cheers, Ecuadorian Ministry of Culture, your logo is the best.

How to have a healthier relationship with your phone

    A few years ago, a Google employee sent an email to thousands of her co-workers: What if for six weeks straight, you spent one night per week without technology? The email was from Laura Mae Martin, Google’s executive productivity adviser, a role that, among other things, was created to help staff members foster healthier relationships with their gadgets and apps. After she sent the note, Ms. Martin was flooded with responses from coworkers eager for a respite from some of the very products they helped build. Thousands of employees have since participated in the annual “No-Tech Tuesday Night Challenge,” said Ms. Martin.

    The problem she was trying to solve isn’t unique to Google workers. One survey found that Americans say they spend too much time on their phones. But dramatic solutions – a digital detox, a phone downgrade or a complete exit from social media – may feel impractical. 

    Is it possible to have a healthy relationship with technology while still using it daily? Fortunately, according to experts, the answer is a resounding ‘yes’ and here are a few things you can try:

    First, start with one simple question.

    You know that urge you get to reach for your phone without realizing it? And then, before you know it, you’re an hour into a social media binge? If you want to peacefully coexist with technology, you need to get a handle on those impulses, said Richard J. Davidson, the founder and director of the Center for Healthy Minds at the University of Wisconsin-Madison. According to him, people should start by noticing when they have an urge to lift their phone or open social media on their browser window. By becoming conscious of what you’re about to do, you’re interrupting an automatic behavior and awakening the part of your brain that governs self-control, he added. As one research article suggests, awareness of your actions can help you rein in bad habits.

    Secondly, take the “mobile” out of your mobile devices.

    Dr. Anna Lembke, a professor of psychiatry and addiction medicine at Stanford University School of Medicine, said one of the biggest problems with smartphones is what she calls “texting while running to catch a bus.” Using our devices while we’re on the move – walking from meeting to meeting, taking a child to school or catching a bus – prevents us from being more engaged in our lives, Dr. Lembke said.

    One way to create harmony with technology is to limit your phone use when you’re on the move. Headed out for a walk? Turn off your notifications. Going to grab a coffee? Leave your phone on your desk. If you’re feeling brave, try powering down your phone while in transit. It won’t buzz with notifications, text messages or phone calls, which Dr. Lembke said could help you focus on the world around you.

    Last of all, make technology work for you.

    One thing experts agree on: To forge a healthy relationship with technology, you need to be in control of it and not the other way around. Think about your gadgets as tools that you decide how to use. 

    “Make it work for you, not against you; whether it’s an email program or your dishwasher, it’s the intention behind how you’re using it that really makes the big difference”, said Ms. Martin, the productivity expert at Google.

Is English language teaching for you? A guide to a new career 

Marie Therese Swabey

June 14, 2021

Whether you’re just starting out or thinking of a career change, teaching English as a foreign language is one of the most rewarding professional journeys you can embark on.

In English language teaching, there is a lot of career potential. As you develop your skills and take on more responsibilities, you can enjoy a long-term career. Many professionals become senior teachers or teacher trainers, or move into management or materials writing.

Why become an English language teacher? 

There are lots of reasons you might want to become an English language teacher. For a start, you can make a real difference in people’s lives. According to a 2019 survey by Wall Street English, 18% of professionals who have learned English report that they feel happier at work; 12% say they feel happier in general; and half of English speakers earn 25% more because of their language skills.

Moreover, English language teaching is an immensely flexible profession. You can decide whether to take a public or private job, or offer lessons on your own. Your working conditions are flexible too. You might prefer to work in a local school or academy, but many English language teaching jobs also allow you to work online from home. And if you’re feeling adventurous, there are lots of opportunities to live and work abroad, in a new country and culture. If you do travel further afield, you might even learn a new language of your own.

English language teaching is a career that encourages creativity. You’ll become an expert at designing lessons and making learning materials to meet the needs of your students. Best of all ... it’s fun! You spend your day with interesting, engaging people who are keen to learn. What could be better than that?

What do English language teachers do every day? 

It probably goes without saying that language educators teach students English on a day-to-day basis. But there are plenty of other aspects to the job as well.

English language teachers assess their learners through quick tests and official exams. They use this information to define learning objectives, and then plan courses and classes that meet their students’ needs.

Language teachers use a range of coursebooks and English language teaching materials, including a variety of audio, visual and digital tools. At the same time, they find and create teaching and learning materials of their own.

In the process of developing learners’ reading, listening, speaking andwriting abilities, teachers also help students develop confidence in presenting and communicating ideas. Furthermore, language teachers encourage students to develop important 21st century skills, such as creativity, collaboration, leadership, autonomous learning and adaptability. These skills are transferable and will help learners in many areas throughout their lives.

What do you need to become an English language teacher? 

Being a good English teacher requires more than just being able to speak the language fluently. You’ll also need a comprehensive knowledge of English grammar, pronunciation and vocabulary, combined with excellent communication skills. Teachers of young learners will also need to have an understanding of how to teach engaging, effective classes to children.

It helps if you are comfortable speaking in front of other people, managing groups of learners, and able to plan and organise your time. And it’s important to have a friendly, sympathetic nature and a good degree of cultural sensitivity. After all, you’ll be working with people from all over the world and all walks of life.

Where can you teach? 

There are opportunities to teach the English language almost everywhere. For example, you can teach English in an Englishspeaking country such as the UK, the US, Canada, Australia, New Zealand or Ireland. You’ll find many private and public programmes and classes for people who have come to work or study, and who need to improve their English.

Alternatively, you can teach English in schools and universities in countries where English is the official language – but not always how people communicate on a daily basis. Nigeria, Malta, India and Sierra Leone are examples. You might also prefer to teach in non-English-speaking countries, where you’ll have the opportunity to immerse yourself in the local culture and learn a new language too.

In terms of teaching environments, there are opportunities to teach in private academies, public schools, universities, offices, private homes and online. 

Who do you teach? 

There is an extensive list of people who want to learn to speak English. Many teachers start out with a variety of class types to find out which they like best. Your options include (but are not limited to):

• • adults in private groups or one-to-one classes
• 
  
• • adults in language schools, colleges or universities
• 
  
• • professionals such as business people, medical professionals, pilots, etc. who require English for a specific purpose
• 
  
• • students who are preparing for an official exam
• 
  
• • people who have moved to an English-speaking country and need to improve their English 
• 
  
• • young learners in one-to-one classes or groups, or online
• 
  
• • young learners in private language schools, or in secondary/ primary schools.

What is Validity?
by Evelina Galaczi
July 17th, 2020

The fundamental concept to keep in mind when creating any assessment is validity. Validity refers to whether a test measures what it aims to measure. For example, a valid driving test should include a practical driving component and not just a theoretical test of the rules of driving. A valid language test for university entry, for example, should include tasks that are representative of at least some aspects of what actually happens in university settings, such as listening to lectures, giving presentations, engaging in tutorials, writing essays, and reading texts.

Validity has different elements, which we are now going to look at in turn.

Test Purpose – Why am I testing?

We can never really say that a test is valid or not valid. Instead, we can say that a test is valid for a particular purpose. There are several reasons why you might want to test your students. You could be trying to check their learning at the end of a unit, or trying to understand what they know and don't know. Or, you might want to use a test to place learners into groups based on their ability, or to provide test takers with a certificate of language proficiency. Each of these different reasons for testing represents a different test purpose.

The purpose of the test determines the type of test you're going to produce, which in turn affects the kinds of tasks you're going to choose, the number of test items, the length of the test, and so on. For example, a test certifying that doctors can practise in an English-speaking country would be different from a placement test which aims to place those doctors into language courses.

Test Takers – Who am I testing?

It’s also vital to keep in mind who is taking your test. Is it primary school children or teenagers or adults? Or is it airline pilots or doctors or engineers? This is an important question because the test has to be appropriate for the test takers it is aimed for. If your test takers are primary school children, for instance, you might want to give them more interactive tasks or games to test their language ability. If you are testing listening skills, for example, you might want to use role plays for doctors, but lectures or monologues with university students.

Test Construct – What am I testing?

Another key point is to consider what you want to test. Before designing a test, you need to identify the ability or skill that the test is designed to measure – in technical terms, the ‘test construct’. Some examples of constructs are: intelligence, personality, anxiety, English language ability, pronunciation. To take language assessment as an example, the test construct could be communicative language ability, or speaking ability, or perhaps even a construct as specific as pronunciation. The challenge is to define the construct and find ways to elicit it and measure it; for example, if we are testing the construct of fluency, we might consider features such as rate of speech, number of pauses/ hesitations and the extent to which any pauses/hesitations cause strain for a listener.

Test Tasks – How am I testing?

Once you’ve defined what you want to test, you need to decide how you’re going to test it. The focus here is on selecting the right test tasks for the ability (i.e. construct) you're interested in testing. All task types have advantages and limitations and so it’s important to use a range of tasks in order to minimize their individual limitations and optimize the measurement of the ability you’re interested in. The tasks in a test are like a menu of options that are available to choose from, and you must be sure to choose the right task or the right range of tasks for the ability you're trying to measure. 

Test Reliability - How am I scoring?

Next it’s important to consider how to score your test. A test needs to be reliable and to produce accurate scores. So, you’ll need to make sure that the scores from a test reflect a learner's actual ability. In deciding how to score a test, you’ll need to consider whether the answers are going to be scored as correct or incorrect (this might be the case for multiple–choice tasks, for example) or whether you might use a range of marks and give partial credit, as for example, in reading or listening comprehension questions. In speaking and writing, you’ll also have to decide what criteria to use (for example, grammar, vocabulary, pronunciation, essay, organisation in writing, and so on). You’ll also need to make sure that the teachers involved in speaking or writing assessment have received some training, so that they are marking to (more or less) the same standard.

Test Impact - How will my test help learners?

The final – and in many ways most important – question to ask yourself is how the test is benefitting learners. Good tests engage learners in situations similar to ones that they might face outside the classroom (i.e. authentic tasks), or which provide useful feedback or help their language development by focusing on all four skills (reading, listening, writing, speaking). For example, if a test has a speaking component, this will encourage speaking practice in the classroom. And if that speaking test includes both language production (e.g. describe a picture) and interaction (e.g. discuss a topic with another student), then preparing for the test encourages the use of a wide range of speaking activities in the classroom and enhances learning.
