This week we’re looking at a popular article again, but one that touches upon a further type of scientific writing that’s especially important when you embark upon a new direction of research or learning – that is the review article. Review articles are used throughout academia as a way to bring together the major pieces of work within a field and give some form of commentary on them. Review articles might be used to give context to a field, show the progress made within a field, or to try to understand the truth within fields where seemingly opposing ideas have been suggested. In the case of this article, it is to provide an update on the recent progress made within one small part of the realm of biophysics. This article brings together ten pieces of modern research, and some additional quotes and thoughts of scientists, to show the current state of our abilities to manipulate ‘microswimmers’.

Your task this week is to:

  • Read the article
  • Come up with some skim-read questions and answer them
  • Answer our comprehension questions
  • Answer our three summary questions

We’d then like you to go further and:

  • Choose one of the articles that are linked within the piece to read (there are ten links, but only eight of them are open-access so choose one of those).
  • Summarise that one article in a short paragraph.

There are no sections, so we’ll simply list the summary questions rather than presenting them in a Cornell-notes style. Do try to make use of Cornell notes in your own note-taking though – there does seem to be some benefit in note-taking by hand as described in this piece by the Learning Scientists.

 COMPREHENSION QUESTIONS

  1. What is a microswimmer?

 

  1. What are the advantages to using light to direct microswimmers over something like electric or magnetic fields?

 

  1. How does Jinyao Tang use light to steer microswimmers?

 

  1. How does Jinyao Tang use light to power microswimmers?

 

  1. Why is swimming at the microscale different to the macroscale?

 

  1. What are the advantages of using ‘chassis from nature’ and starting with biological cells?

 

  1. “Some algae, for example, can move more than ten times their body length per second, which is more than a speeding car can do on the highway.” Find values and perform calculations to prove/disprove this statement.

 

  1. What is phototaxis? Give examples.

 

  1. How do Chlamydomonas manage to respond to light?

 

  1. What unanswered questions are there surrounding microswimmers and their eventual use within the human body?

 

  1. Describe the process behind the movement of Celia Lozano’s spheres.

 

  1. “To make a microscopic particle respond to light, it just needs to be asymmetrical in some way.” Analyse the truth behind this statement using example microswimmers from the article.

Now, find one of the linked articles that you're most interested in and read it (making notes as we've learnt to do) and then summarise the article in a short paragraph - what are the key things to know about this paper?

SUMMARY QUESTIONS

 

What different methods have scientists used so far to manipulate the motion of microbots and bacteria? What do you think are the positives and negatives of these methods?

 

 

How could synthetic microbots and hijacked biological cells be used? Are there differences between them?

 

 

What issues can you foresee within the field of microswimmers?

Your additional summary question is to summarise one of the linked articles from the piece in a short paragraph. Please ensure you say which article you are summarising – preferably in a Harvard Referencing style (to give you practice at working out what this looks like).

 

FURTHER READING

 

There is a famous lecture by Richard Feynman entitled Plenty of Room at the Bottom which discusses the early ideas around miniaturisation. You can see a version of the lecture here can access a transcript of a slightly different version of the lecture here.

GENERAL INFORMATION

Remember, reading a paper isn't like reading a piece of fiction or a newspaper article. Don't get frustrated if it doesn't immediately make sense - you might need to do a little research of your own to understand some of the ideas. This article gives you an idea of how scientists read differently.

Each question refers to a specific part of the paper e.g. Page 2, Column 3 is written as (P2, C3).

Next week, we'll publish solutions to the questions and the best submitted summaries from students across the country.

NEXT WEEK

We'd really like to hear about any topics/article you'd like to look at over the summer so please email in any suggestions you have for new aspects of physics that you'd like to look at!
