Does anyone know when Results come out for Summer exams?
27th I heard... could be wrong - Luc Tardy
Last week of term now! Have managed to get a fair bit of revision done over the last few weeks thanks to a revision timetable though I'm quite behind on my plan. Microobiology has been hard to revise as some of the lecture slides aren't too clear and I find that 'Principles of Modern Microbiology' isn't detailed enough in some areas. Genetics has been great to go over as we've been given some excellent notes and there are plenty of good text books in the library. I still haven't met with my P. Tutor yet to sort out my module choices for next year, but I reckon I'll crack on with physiology and pharmacology. I think I will be glad to see the back of compulsory friend feed if I'm honest. I think FF is a great tool for networking with other students and getting help, but I won't miss having to post my diary or articles. Friday is my last practical and then I'm finished! - Joe Bailey

During the #BS1005 lectures I remember asking whether phages could be used to combat bacterial disease. The lecturer didn't seem that sure but whilst revising today I came across this video and discovered there is actually such a thing as 'Phage Therapy'. It seems to make more sense to fight nature with nature, but phage therapy research and development has apparently lacked funding. Maybe it's the way forward for targeting super-bugs? - Joe Bailey from Bookmarklet
This was the topic I used for my scientific write-up for AS-level bio coursework after I was fascinated watching a documentary about phage therapy. http://video.google.com/videopl... One of the problems I read about with targetting super bugs is that for every strain of bacteria, a phage needs to be cultivated specific to the strain. So in indvididual cases, it... more... - Xanthe Simpson-Gray
Thanks Xanthe. That documentary looks really interesting. Yeh, when I read up it seemed that specificity is quite a disadvantage. - Joe Bailey
See it isn't a disadvantage in some applications as it allows you to target a bacterial infection without affecting natural microflora. It's just an example that there will never be a cure-all. Edit: I'm not actually able to watch the video so apologies if any of this was mentioned. haha - Xanthe Simpson-Gray
Interesting treatment, should not have watched whist having a cup of tea tho :( - Remi Mckenzie
Wow, today has been really productive - I have had time to go over some of the lectures from the last few weeks at an unhurried pace. For the first time since October it feels like I can actually enjoy learning the material rather than constantly jumping through assessment hoops. I can also look into more depth on the things that I am interested in which is a privilege I didn't have the time to do for a while. So this week has been very enjoyable. I think I'm going to go for a physiology and pharmacology degree stream but am still not sure. The thought of never having to do ecological sampling again in my entire life is an attractive one! - Joe Bailey
BBC iPlayer - Beautiful Minds: Tim Hunt - http://www.bbc.co.uk/iplayer...
Interesting documentary on Sir Tim Hunt, a Nobel Prize winner. He discovered the protein which controls cell division and now works for cancer research. I can identify with his questioning mind very much and found it interesting getting a look at some of the simple lab methods which he used (and we are able to do) in order to make quite profound discoveries. This is relevant to a number of modules, but especially #BS1003 and #BS1005. - Joe Bailey from Bookmarklet
BBC News - 'One million' dead sardines clog Redondo Beach marina - http://www.bbc.co.uk/news...
Decomposing bacteria cause the death of thousands of fish. Relevant to the Dr. Clokie's material in #BS1009. - Joe Bailey from Bookmarklet
Where did you hear it that the cause was decomposing bacteria? I thought it was due to the fish themselves using up all the dissolved oxygen in the water. - Luc Tardy
Just realised I haven't written my diary for a little while. I think my mind has been on getting these last few days out of the way. Was really glad to get the report in this morning for #BS1013 - it marked the end of the rather intense last few weeks. I have to say though, I don't think this term has been as hard as last term, though that might be because I especially found chemistry a struggle whereas most had done it before. Found the physiology lecture very interesting yesterday - the kind of thing you can wow people with over the dinner table. I can just imagine telling my Grandad that he only has a third of his alpha motor-neurones left in his hand but not to worry as they can branch to other muscle fibres! Enjoyed the evolutionary biology lecture today. These should be interesting as I am a creationist. But I do believe in natural selection and adaptation, I just don't accept molecules to man evolution. It will be good to hear the different arguments. Now to do my genes report and #BS1011 work! - Joe Bailey
Wolf child: Supatra Sasuphan, 11, is happy to be named the world's hairiest girl - Telegraph - http://www.telegraph.co.uk/health...
This girl has Hypertrichosis. The captions don't explain which kind, but one variety of the disease is caused by a mutation on the x-chromosome so is sex-linked. You can read more about it here: http://en.wikipedia.org/wiki... . Relevant to #BS1005 - Joe Bailey from Bookmarklet
There was a documentary on this on channel 4 (how did you guess?), you might still catch it on 4OD but it was on about a year ago. - Matthew Taylor

Not sure if this is the clip that Prof. Hart was trying to show us earlier. - Joe Bailey from Bookmarklet

BBC News - World's first flu-resistant GM chickens 'created' - http://www.bbc.co.uk/news...
BBC News - World's first flu-resistant GM chickens 'created'
As usual, the BBC isn't particularly accurate in their attention-grabbing headlines. These GM chickens are not flu-resistant - they can catch it. But they are unable to spread it. This is also more effective than vaccination because vaccinations can loose their effectiveness if the virus mutates, whereas these chickens will not be affected by viral mutations - they will still be unable to spread the disease. Relevant to #BS1009 and #BS1005. - Joe Bailey from Bookmarklet
hmmm wonder what they taste like? And by not spreading it do you think that means they cannot cough (or sneeze?)!!! - Adam
Tastes like chicken. - Dr Alan Cann
Really glad that the plant practicals are finished in #BS1013 and the essay is out the way for that module as well - I can now just focus on the lectures. I've found it helpful to try and critique my own essay before I give it in and write any questions I have at end of the essay so the lecturer can let me know whether my concerns are valid. The work's piling up again and it looks like time to look over lectures is fast disappearing but hopefully will get back on top of things soon. The genes essay looks interesting and also helpful in understanding the course material. - Joe Bailey
ARGHH! I don't know if my data is right for part B1 of the practical report. Could someone tell me what the trend should be? Here's my graph... is this right? The brown dots are the pea and the blue dots are the maize
Graph for friendfeed.png
As far as I know, Maize is a C4 plant and C4 plants have higher concentrations of PEPC. The absorbance you're measuring is showing the formation of a complex with the direct product of the PEPC reaction and so, the absorbance should be higher for a C4 plant. I'm not sure why your data doesn't show that, though, I'm afraid. - Xanthe Simpson-Gray
Thanks Xanthe - that was what I was expecting. Not really sure what to do. The same thing happened last week - wrong data from the practical. - Joe Bailey
Could you have got your results round the wrong way? Because my graph looks very similar but my maize and pea lines are the other way around if that makes sense... - Rachel Bell
Possibly. Though I've checked on excel and i'm using the right data. Spose I'll just have to explain that it was disaster and just explain the results that we should have got. - Joe Bailey
There's a lot that can go wrong when measuring the activity of an enzyme so it might just be that. - Xanthe Simpson-Gray
Genetic map of prostate cancer cracked - Telegraph - http://www.telegraph.co.uk/health...
Genetic map of prostate cancer cracked - Telegraph
"They found more than 21,000 mutations – like spelling mistakes – in the seven tumours as well as more than a 100 "rearrangements" where whole sections of DNA have broken free and reattached to other parts of the genome." Sounds to me like the double strand breaks we learnt about in #BS1005 Genes, which result in deletions, inversions and translocations when they rejoin. But for this understanding of the genetic basis of cancer to be really clinically usefu, surelyl many more samples of cancerous tissue must be studied.But it's exciting stuff, though early days as yet. - Joe Bailey from Bookmarklet
BBC News - More gene clues to Parkinson's discovered - http://www.bbc.co.uk/news...
BBC News - More gene clues to Parkinson's discovered
#BS1005 It seems that as we advance in our understanding and ability to study genetics, more and more diseases previously thought to be caused by environmental or other factors are now suspected to be genetically based. Here is one example - Parkinsons disease. However, though breakthroughs in understanding of the genetic basis of diseases are potentially revolutionary in terms of treatment, they require a lot of work. In this example, a total of 33,000 people were sampled and their DNA compared. Researchers from six different countries were involved. There's an ethical question here: how do we decide which diseases warrant this amount of time and money in genetic research? - Joe Bailey from Bookmarklet
Very interesting :)) - Persefoni Ioannou
This term has so far been so much more enjoyable without Chemistry to weigh me down. Things are a lot more digestable and understandable, and I have really appreciated the quality and structure of the teaching in the Genetics course. It seems that the whole purpose of the course has been designed to actually help us grasp the the concepts of genetics rather than just endlessly put us under pressure with constant assessment and testing - the practicals and tutorials have been great. The plant physiology practicals have been hard, and I think it would be a good idea to pool our class data before doing the write up, as last time we got wrong results which made the interpretation near-on impossible. Would also appreciate longer for the write up than 3 days, as we need time to get help if we get stuck. A few personal circumstances have made concentration on Uni extra hard this week so am quite behind, but am thankful for Saturday to catch up on things (hopefully!). Roll on next week! - Joe Bailey
#BS1011 - Stuck on sheet two of this weeks assessment. Have changed the format to 'Number' but it doesn't seem to have done much - can't work out how you get it recognise scientific notation. Can anyone help? (Or is this cheating)
Lol, no worries, have worked it out now! - Joe Bailey
#BS1013 - In our Plant Physiology practical on Friday we were really rushed and my pair ran out of time to do part A3 of the experiment. What do we do for the practical write up when we haven't done this part of the experiment? Has anyone else had this problem?
#MyDiary 31.01.2011
Although some aren't happy we have big gaps between our lectures, I've found it helpful as I seem to get a lot more work done in the Library than at home. Today has been good - the first Genes lecture wetted my appetite though I had heard most of the content before and the Physiology tutorial in the morning gave me an idea of the work required for the next couple of weeks of tutorials. I just hope I can keep on top of everything this term - it looks like we're going to have a lot of practical write ups to get in. - Joe Bailey
Does anyone think that neglecting Dr. Evans stuff in revision and focussing on Drs. Ryder and Rawlins' topics is a good method? After all, there will only be 1 out of the 4 questions in the #CH1070 exam that are actually on his topics and we only have to answer 3/4 questions. Any thoughts?
I would definetely advise learning all the material - its very risky limiting yourself to the 3 questions - you only need one to come up that is 'rubbish' and you will wish you had learnt all of it - Laura
How do you know about the format of this exam? - Alice Baxter
Because you can see a couple of past papers on blackboard. Also, I asked for more past papers at the Chemistry office and they gave me a few years worth. - Joe Bailey
Thanks Laura. Good advice - Joe Bailey
Oh I didn't know they were split like that! Are there 2 questions on organic, 1 on thermodynamics and 1 on kinetics? - Zainab Chaudhary
Yep,2 oganic and 2 inorganic - Hasan Mohamed
When does the office re-open? I want some more past papers to go through. Are you sure they're keeping the format the same for this year also? - Faaiza Museji
Joe is there any possibility you could share these papers? As I and some others went to the office and they wouldn't give us any =S - Rachel Bell
I think the module convenors would be wise enough to integrate chapters in questions, so that every question has a bit of every lecturer's material! Besides, we've got one week between the two exams. That should be more than enough I suppose. - Abdulkhaliq Alsaadi from iPhone
Where are these aforementioned past papers on Bb? I can't seem to find them... *Edit: nevermind (http://ff.im/wBNLp). - Zainab Chaudhary
When working with Gibbs energy figures, is it necessary to convert them to joules/mol^-1 rather than using KJ/mol^-1? Say, for example if I had to work out a Ka value for a particular reaction from the Gibbs energy number?
I'm guessing the question may state what units that it wants the answer in? Not sure though sorry... - Rachel Bell
Hey Rachel. the ques is in Jan 09 Chem paper ques 4b. - Joe Bailey
usually you have to convert units. there is a less chance to make a mistake, because the basic unit is joule/mol, not KJ/mol - Teodora Petrova
Bit confused about something on lecture 2 of Dr Willmott's section. The slide 'Classification of Amino Acids' groups proline in with the non-polar, aliphatic AAs, whereas it is in the Polar, uncharged section 3 slides on. Not sure whether that is intentional or not?
Thanks Dr. Willmott. I had tried doing a #BS1015 search on FriendFeed but it came up with an error message for some reason. - Joe Bailey
do any second years know what happens at the end of the summer exams but before the end of term? Do we have lectures are are we free to go? (Dates: 13 June - 1 July)
In the first year there isn't anything timetabled after the end of exams- there is in second year tho =/ - Laura
Oh what do we have scheduled, Laura? :o - Joshua Bower
@Josh, the last 3 weeks have timetabled stuff for our final year projects apparently - maybe we choose them/do previsional background stuff or something? - Laura
Choosing projects takes place earlier than that, but Laura is correct there IS project-related activity for all second years. - Dr Chris Willmott
Thanks, though I realise my question wasn't very clear. So it seems that after the summer exams the first years are not required to be at university. - Joe Bailey
You still have to stick around though first years I'm afraid. - Lyndsey Wright
So doesn't really answer our question.... what are we actually meant to be doing between finishing our exams and the 1st of July?? - Rachel Bell
There is nothing scheduled for you during that time, but you must be available at all times to go to University, so you must stick around. You'll need to meet with your personal tutor to collect your results towards the end of the unscheduled period. - Joshua Bower
:S So we have to stay around for over two weeks just to see our personal tutor once? Doesn't make much sense :( - Rachel Bell
There may be other things that happen during this time. Careers-type things that I would recommend going to- they are very useful. - Lyndsey Wright
But our attendance is obligitary? :S - Rachel Bell
No attendance isn't obligatory, there are optional career lectures that you can go to. I understand what you are trying to say, and even though, technically, you don't need to go, the university still expects you to be in Leicester and still be available for anything that is scheduled. I know it may seem a little pointless, but you do enjoy spending that time relaxing, which is also very important :D. - Jaspreet Seehra
It is fair to say that any advice being passed down from one year to the next should be considered tentative as use of the post-exam weeks is currently evolving. - Dr Chris Willmott
From Dr Scott: Following the summer examination period, there will be a programme of preparation for the final year research project which all 2nd years are expected to attend. There will also be other events such as a career development day and a training day for students volunteering to act as peer mentors for the incoming 1st years. - Dr Alan Cann
I'm finding the revision for the #BS1015 practical exam on Friday really helpful. It's amazing how much more you can understand with a few weeks hindsight and better knowledge! I can see where and why I went wrong more clearly now. :-)
Snails flash a green alarm light - http://news.bbc.co.uk/earth...
This stood out to me after studying the Green Fluorescent Protein for the tutorial presentation in #BS1015. I wonder if the protein that the snail uses could be isolated and used as a protein marker like the GFP? - Joe Bailey
Our group was given this topic for our tuorial presentation too, and yeh i'm sure if the gene can be identified and located then the gene could be cleaved and then replicated. - Novpreet Rainer
I've been looking at the quiz for Advanced Thermodynamics (#CH1070) and it talks about DH, DS and DG. Did we cover these in the lectures with Dr. Ryder? I can't find anything about them in the lecture slides.
The D stands for Delta (the triangle). I think it's a typo! - Roshan Rupra
D means delta, so yes we did. so DH means enthalpy change etc - Neil Nathwani
Ahh thank you!!!! Please excuse my lack of common sense. I do wonder sometimes how I got on to a Biological Sciences course. :-) - Joe Bailey
Sometimes Dr Ryder's slides had typos where n was shown where it should be the greek letter 'nu' (looks like a V) etc. So I think probably D means Δ. Don't worry, I made the same mistake with the above example :P I was wondering why there were two different equations, one with a 'nu' symbol and one with an 'n'... Lol. - Zainab Chaudhary
Yeah it's delta as people have just said. I've just done that one, though the feedback isn't that useful- it says what equations to use (which I did) but not the answers for each step so I dont know where ive gone wrong :s - Rebecca Suter
Yes Rebecca, I totally agree. I've gone through some of them again and again and had no success and don't know where I'm going wrong. - Joe Bailey
To be fair, I find Ryder's lectures the hardest to revise from. Could be because I find it hard to work through some of the examples he gives when it comes to equations. I'd be clueless if I didn't use books! - Roshan Rupra
Oh good! I'm glad someone else can't get the answers either. I keep redoing them in different ways, but I'm not getting the right answers. - Katie Samantha Jolly
In that case should we get together at the session tomorrow and ask Dr Ryder to help us on those ques? I doubt he'll have time to get round everyone. - Joe Bailey
I having the same issue so I think thats a really good idea Joe! - Grace Hodson
Good! Well not excellent that you're having a problem but it's good to know we're all in the same boat! - Joe Bailey
I think I'm quite comfortable with thermodynamics, and I reckon the revision session tomorrow is gonna be rammed. :/ I hope you guys manage to understand it pretty well in the session tomorrow! - Roshan Rupra
Hey Roshan. If you're OK with it could you let me know how you got to right answer for questions 5 and 6 in the online quiz? That would be so helpful. Don't worry if you're busy though, seriously. Thanks! - Joe Bailey
Sure thing mate. (: But you've gotta subscribe to me before I can send you a direct message, must be a friendfeed thing. - Roshan Rupra
Thanks! Lol, I thought I was but turns out I'm not! All subscribed now. - Joe Bailey
I've been through some of them over and over and eventually i've got the right answer for a couple I got wrong, but I wouldn't be confident with similar questions. I'm not sure if the help session will be any good tommorow- I reckon it'll be full too :/ I'll revise other areas and try them again from afresh and see if I know what im doing :') - Rebecca Suter
Rosh kindly led me through a couple of questions and I see where I'm going wrong now. I hadn't been converting between J and KJ! So may not see you guys at the session tomorrow depending on how I get on!! Sorry. Hope everyone does all right tomorrow (especially my fellow non-chemistry people)! - Joe Bailey
Yeah, i'd done that for some too :). Btw, what happens if we fail this test? Do we resit it in the summer? - Rebecca Suter
I was just flicking through the module hand book and it says that after januray exams if we score either less than 35 marks overall in the module or between 35-40 (thats if we cant make it up in other modules) we will be required to resit the module in september. - Benjamin Tanner
Anyone know whether we still still have a Study and Communications lecture on today? Or have they finished?
Anyone fancy trying to explain Orbitals and Resonance and Nucleophilic Substitution to an ignorant non-chemist (i.e. me!) at some point today or tomorrow? #CH1070
I would appreciate the explanation too... :-) - Rachel Bell
I just need somebody to try and explain it simply to me. I'm free after the dry practical this afternoon and also in the morning tomorrow between the Biochem lecture and the animal and plant practical. - Joe Bailey
OK Rachel, maybe we could book a room in the Library or use the group study area if non are available. Let's see whose interested in coming (and explaining!). - Joe Bailey
That sounds good, I think me, Paul and Nicola were going to try and book a room anyway for Chem revision so that could work well :) - Rachel Bell
Maybe book a room between 11-2 ? Gives us some flexibility? - Rachel Bell
I hate to be a pain but I'm not going to be around tomorrow from 12-2. Could we book it in the morning? Maybe 10-12? If that's a problem don't worry about it. - Joe Bailey
I guess I could go through some of it with you, how about in BS1010 help session? I will speak to u in animal and plant diversity anyways. - Adam
You could always visit Dr Rawlings outside of lectures and the help sessions. He's super friendly and really good at explaining things if you're struggling to understand something. If not, I'm more than happy to try and go over orbitals and resonance with you. (: - Roshan Rupra
Thanks Roshan, I'll have another bash at it this evening but if I'm still stuck I'll drop you a note on FF. Thanks again. - Joe Bailey
Yeah I'm finding it quite hard too, and I did chemistry A-level! Im just gonna keep going through it and just try and memorise it. - Rebecca Suter
Does anyone know whether there is a chance to retake the end-of-term Chemistry multiple choice exam in January if we do really badly on it? Or do you have to retake the whole module in September?
There are no retakes in January but I'm not sure what the arrangements are for #CH1070 - concentrate on passing! - Dr Alan Cann
Wading through my notes I feel overwhelmed by the huge amount of information necessary to intake for someone who hasn't done chemistry before. I wouldn't mind so much if we were only examined after Christmas but it is really tough to give us an exam before. The amount of time necessary to learn the lectures for me in term-time for the Dec exam means that everything else really goes to the bottom of the pile and I can't do as well as I would like in other areas. - Joe Bailey
I agree Joe. I feel we are at a major disadvantage because we didn't take Chemistry at A Level :( - Katie Samantha Jolly
Hi Katie. How are you finding it at the moment ? Do you think it's worth raising with the 'course reps'? - Joe Bailey
I don't know Joe. What would they do? I feel like there should be more warning if you're coming to the course without Chemistry! And maybe a bit more help if you don't have it. What should we say to the reps? - Katie Samantha Jolly
hey guys if u need help with the chem give me a shout out i may be able to help!!..=D - Krupa Patel
Thanks Krupa. :-) - Joe Bailey
It has to be retaken in September. - Roisin Thomas
I agree Joe, I think that more emphasis needs to placed on doing A level chemistry on open days, prospectuses etc. I was assured that I wouldn't be at a major disadvantage if I hadn't done A level chemistry but I don't feel this is the case... - Rachel Bell
I think you would have to retake the multiple choice in the summer exam time? Not sure. Anyway jo, your a very intelligent chap, I doubt you would need too! - Oliver Charity
remember the chemistry computer classes are there and the best way place to go if your struggling. - Oliver Charity
some universities actually ask for A-level chemistry to do there biological science courses, and not biology. however i personally feel most of A-level chemistry is being covered in the CH1070 quite well considering. think chang may be a book to buy... an A-level chemistry revision guide may be useful as well :), sure helped with my A2 exams - Christopher morton
I didnt do A-level Chemistry and I do think think its a big disadvantage. Most of the time I understand but its just so much to take in that I can't remember it all! - Alice Round
It may seem hard now having not taken A-level chemistry, but remember you are taking a core chemistry module now so it will seem difficult. I've found that after this module is over you do not use the chemistry hardly at all. Obviously a basic chemistry understanding is useful. I guess what i'm trying to say is that not doing A-level chem may put you at a disadvantage for the #CH1070 module, but it should not put you at a disadvantage for all of your other modules. So dont worry too much! :) - Hollie Smith
Hi Pardina, that would be great if you could do that, thanks. My main problem is that we have an end of term assessment which actually contributes towards the final grade, rather than having it in January. This means that most of my private study in term time has to be on Chemistry and I end up neglecting other subjects which I not only enjoy but could also do much better in. More Chemistry help sessions would be good, but ultimately I think it's the timing of the exam which is the biggest problem for me. - Joe Bailey
Thanks Hollie, that's a great comfort!! - Joe Bailey
Just remember that magic number - 40%! And buy an A-level chemistry book. A lot of it you won't need to know in detail again, so focus on passing and not having to retake and don't worry about getting a first in everything! - Alice Merrill
Lets try not be pessimistic and hope for the best =) - Khetase Chiwowa

Dwindling biodiversity raises disease risk in humans, study finds | Environment | guardian.co.uk - What does everyone think to the quote below??
"Prof Os Schmitz, an infectious disease ecologist based at Yale University in New Haven, Connecticut, agrees with Keesing that loss of biodiversity is likely to increase the transmission of disease. But he worries that there is a trend among conservationists to protect "good" species – but dismiss pathogens as "bad" species. "We celebrate diversity for its ecological services to human welfare, but we only celebrate it if it enhances human welfare," said Schmitz. "Disease species are also part of global biodiversity, and in fact diseases may be agents that spur the evolutionary processes that lead to biodiversity."" - Joe Bailey from Bookmarklet
Should we promote or fail to abate human disease because it spurs "the evolutionary processes that lead to biodiversity" ?? I don't think so. - Joe Bailey
