This video shows neurons (in green) that control instinctive behaviours such as defence. They are located in the periaqueductal grey or PAG: an area in the midbrain with an important role in behavioural responses to stressors like threats or pain.
In recent years, big data is a term that invaded the media and that the public has been exposed to. From finance to social networks, data are collected to infer trends and sometimes to manipulate opinions as it has been observed during recent elections. However, the public is less aware of the big data revolution that is occurring in biology. In this post, I would like to begin by explaining how big data is used in biology, and more specifically in genomics, and end by sharing some thoughts on how big data is currently shaping research.
In the early 2000’s, a battle opposed J. Craig Venter and the International Human Genome Sequencing Consortium to publish the first sequencing data of the human genome. The race produced two articles published in Science and Nature but more importantly, opened an intellectual revolution giving new possibilities to explore the 3 billion base-pair DNA sequence of the human genome in its entirety. Even if sequencing was used a long time before, sequencing the human genome opened the door to sequencing the genome of many other species. Continue reading “On big data in biology”
Biological research has never been more vibrant and interesting, but the flipside is an ever-increasing number of studies to keep track of. Gone are the days when the ponderous intellectual could leaf through the latest journals while twirling a goblet of brandy or smouldering pipe. Therefore, I had to come up with other ways to keep up with the scientific literature.
The first is to spend a few minutes to learn how pubmed searches work, watch a tutorial here. Then register for “My NCBI”, which is free and allows you to setup automated pubmed searches and have the website output any new results every day via email. I have searches setup for specific scientists I wish follow, like “gross cornelius[Author]” (use without the quotation marks). I also have more complex searches for keywords in particular journals such as “(Lateral Geniculate) AND (“Nature”[Journal] OR “Science (New York, N.Y.)”[Journal] OR “elife”[Journal])” (the list of journals in my actual search is very long, again, don’t include the quotation marks, but keep the square brackets).
When I was asked to write a post about the last Science & Society talk we had at our EMBL site in Rome I was particularly excited. Science & Society lectures are all about the impact of science on society and the speakers work in fields that are of utmost relevance to the public – but often misunderstood.
Most recently, Giuseppe Testa spoke at EMBL Rome. Testa works on epigenetic regulation, cell reprogramming and disease models. His talk dealt with the impact of epigenetics on society, which is a concern for all of us working at EMBL Rome, considering that we recently chose to rename our unit “Epigenetics and Neurobiology” to focus the interests of new group leaders in these two fields.
