Mendeley: manage your papers and sync them

If you are in research you read a huge amount of papers, which you would like to retrieve later according to a keyword, author name, or any other method that works for you.

Right now it’s plenty of this tool around, starting from Papers, to Referencer which is my choice right now. However having your papers available when you don’t have your laptop and having them from an on-line resources is also a good idea and CiteUlike is my solution for now.

One thing that I am really keen to have is a synchronized way to manage this two worlds. Right now SyncUThink is a tool developed to do just that. We even have interviewed the developer some time ago.

Today a new guy is coming up and it’s called Mendeley. One of the innovative features that this software is able to offer is the automatic synchronization between the offline and the online world.

The software consist of two part, the desktop client and the website. On the website you can have the classical social soul and on the desktop you can use the software to search your papers and find that piece of information that you are looking for.

The Desktop client (Qt based in my case) has a pretty neat interface and the search for authors is one of my favourite tool to search the articles. And the synchronization is only one click away. Pretty slick, isn’t it?

It’s worth to give a shoot.

Note: I discovered this software directly from an e-mail sent to me by Victor. He found this blog when he googled for open science. This made me quite happy :).

TiddlyWiki mandatory plugins

So if you are using tiddlywiki you know everything, if you don’t you maybe want to take a look to it.

What is tiddlywiki good for?

For me is good as an advanced lab book. Yes an electronic labbook. All my biology friends have a really good fashion old school labbook, but I’m not too much into paper and I keep forgetting things.

More over is really a pain to search on the paper… I have different thoughts and ideas that are completely disconnected and only at the end they make sense (sometimes…)

So here the User Case:

  • Able to write any piece of text/idea quickly in a not complicated way
  • Able to tag it in a flexible way and give it an automatic datestamp
  • Able to have this tool always available.

If you recognize this, you want to give a try.

Now I want to suggest you two plugins (I started to write this post because the second one was really hard to find again, so I will put the right link here. I don’t think google is going to care too much about this blog, but anyway it could help a bit)

First of the latex plugin (if you don’t know what is LaTeX … well I’m sorry..)

The second one is the listTaggedTiddlers

Give it a go.. It’s really cool.

Bioinformatics survey is over

The bioinformatics survey proposed by Bioformatics zen during july is over.

survey

As expected the USA is the country with the numerous entries, but France in second place looks to me as a surprise.

As usual Italy is one of the last country for number of entries (but at least is there :))

Into macro regions the Europe is rocking!

Have a look the other initial charts here.

More to come.

Cold fusion. It just works.

Arata Phenomena: this is the name given by the scientists to the reaction of cold fusion obtained by Arata in Japan just few hours ago.

The deuterium (isotope of the hydrogen with one neutron) was pumped into a reactor where there was a cathode formed by 35% of palladium, and 65% of zirconium.

The reaction started to produce energy activating a thermic engine. After one hour and half the experiment was stopped to measure the amount of Helium-4 produced, sign of the reaction.

That’s a really good news

Adding modeling in the wet lab

Modeling in biology is a kind of Cinderella branch of the field. Is not central as it is in physics and there is a lot of skepticism about it, especially from the wet lab guys. Biology has started as a descriptive subject and then it went to the quantitative approach.

Quantity. That’s exactly what you need if you want to do some modeling, that at the end of the day is crunching some numbers using a computer.

Let me just make a comparison with the engineering field. This guys usually:

  • think about an idea
  • model it to test if it’s worth to build it and it will resist
  • build it in the reality

If for example you’re building an house, you hit a button and the program is going to make all the calculation to see if the house is safe and it will last, or it will just collapse under its own weight. Actually you’re testing your idea, modeling it on a virtual space.

In biology you have the same kind of approach:

  • think about a question
  • design the experiment to try to answer the question
  • do the experiment

The modeling should be one point of the design part to let you know if your experiment would discover something or not, so you can save time and know on which parameter focus your attention or which proteins seem to be the important key role. It should help the biologist to design better experiment.

For example you have a cascade signaling involving something like 15 proteins. If you have a tool that is going to predict that the most interesting reaction over there involve protein 2 and protein 3 you can focus your attention over there, avoiding the scan of all the other proteins in the first place.

To do that we need of course a really rock-solid modeling framework and from the other hand a really easy and fast way to use it.

We are quite far from there, but it looks to me like an intriguing prospective.

Biocompass: get your bioinformatics direction

When I was at the predoc course in Heidelberg I saw that a lot of my friends, real experimental biologists, where a little bit confused in which tool use to do a bioinformatic job and where to grab it.

On top of that there was another problem that was related to the big number of bioinformatics software available out there and how to make a choice between them.

So I come up with the idea of the biocompass that I will try to explain.

Biocompass will be a web-portal where scientists can ask question about specific bioinformatics topic and other user can try to give an answer, giving the idea where it’s worth to look.

Let me try to explain it with some examples:

Sarah is an experimental biologist and she has a sequence of a DNA. She want to know if this sequence is a gene and, in that case, if it function is known. However she doesn’t know how to do it.

She comes to biocompass web-portal and post the question over there. The systems checks if there are similar questions already asked, if they are the system is going to show the first 5 hits that are similar to the problem proposed by Sarah.

If Sarah is satisfied with it, she will accept the answer and the system will store original question into the database for further reference and to increase the precision of the system.

In the other case Sarah decide to post the question to the attention of the other people subscribed to the portal.

The system will ask her to categorize the question into one of the available categories, like for example genetic, molecular dynamic, philogenetic, simulation, …

She will be guided through an easy but systematica process to end up with a really well organized entry.

The system will propose a set of tags already present in the database to atick them to the question, to have a more fine-grained search later on.

Now comes another important innovation about biocompass, the filtering. Nowadays there is too much information that cannot be processed in a reasonable amount of time. That’s why we need system to filter and select only the information that we really want to know.

Andrea is a bioinformatician working on genetic alignment. She has subscribed to biocompass and she decided to follow the genetic category only. This means that she is going to receive update only when there is a new question in the genetic category, ignoring all the others; they are not is field and she cannot be helpful over there.

Andrea sees the new question coming. She is following the new questions with a RSS feed that she prefer over the mail system.

She knows the answer. A BLAST search can give an hint about the DNA sequence. She suggest to use BLAST as a starting point for the research, linking it to the BLAST page entry.

This is an internal page in biocompass, where there is a small description about the software, the link to the ufficial website, and the number of user that have found the tool useful or not to solve this problem.

The rating is given by other user that has found the software good to solve this kind of problem, giving an idea how good and useful is the software itself.

The system shows also a bunch of related softwares that can be useful to solve this kind of question (ClustulW, BLAT, …)

Sarah gets the update from biocompass with the answer coming from Andrea. She now can start the investigation about her DNA sequence.

Here we are. Biocompass has act as a real compass, to give the direction where to start. This time the needle was pointing to BLAST direction, next time is going to point somewhere else.

Science and art. Is the gap so huge?

At the BioSysBio Conference which I have attended in London this April there was a lot of things going on. An interesting bit was the workshop on Openscience notebook, on which I am really interested and thrilled. I’ve touched this subject in the past, however I will blog about this later on.

At the social dinner there was an exhibition from some artists and designers from the London Royal College of Art.

That’s how I knew Tommaso and we started to speak about it. I gave my “scientific” point of view, mainly answering what is possible now, what will be possible in future and what, according to the accepted paradigma and the availability of informations is not possible at all.

The topic was trying to think about new concept ideas grounding them on a scientific point of view.

To be honest I always saw this kind of contamination between the two realities with a lot of interest.

I am quite convinced that a scientist discovers something not when he/she is in the lab, but when he/she is outside the lab. Of course the ability to test the idea and grounding it on the science bases with model,measures and a theory happens in the lab and research work, but the original concept, the main idea is a sum of some different stimuli coming from different sources where art play a really big part.

These projects seems to demonstrate that also the other way is possible and science can influence art and design in a really intriguing and prolific way.

Maybe the difference between humanistic subjects and scientific subjects is only a matter of language and convention, and the holy war that usually it’s on between this two fields it’s just a matter of misunderstanding.

It’s time to move foward and trying to rethink the association between the two fields. Also from a teaching point of view.

Another blog about bioinformatics

So, some of my friends has set up another blog on Bioinformatics.
The address is phdblog
and the subtitle it’s just true.

70% of what we do doesn’t work

I would just increase the percentual, but hey, we should trust us and hope for the best.

It’s just a new born blog, few articles right now, but it’s growing well.
Keep on eye on it, you wouldn’t regret.
