Science the top 1 word of 2013 according to Merriam-Webster dictionaries.
While Oxford Dictionaries have chosen selfie as the word of the year, the Merriam-Webster dictionaries used quite different criteria to establish their 2013 word top and the winner is science. Why so many of us were interested in science during the past year has been a matter of intense discussion in the past couple of days. But one of the major distinguishing traits of science is that it is future-focused above all; so should we have even higher expectations for 2014?
Synthetic DNA fossils have been created but what can we expect from this new tool?
Protocols are for researchers what cookbooks are for Chefs: for some, scratchy notes; for others, the Bible. Just like a Chef who expects to end up with a great desert when following his favorite Creme Brulee recipe, scientists perform protocols with particular aims in mind. Except for… – what can a protocol for making synthetic DNA fossils be used for?
The silk road to epigenetics: the driving forces behind silkworm domestication
Silkworms are under the spotlight after the publication of a study where epigenetic modifications are compared between wild and domesticated varieties. This work unravels the mechanisms that led to the domestication of silkworms and the improvements in silk production about 5000 years ago in China.
The domesticated silkworm, Bombyx mori, was the focus of the study by Xiang and colleagues, published online on the 23rd of September 2013 in the journal BMC Genomics. Photo: Wikipedia
The domesticated silkworm has been artificially selected to produce more and better silk, the luxurious product that is so valued worldwide. It has been estimated that silk production has increased up to tenfold with sericulture (the breeding of silkworms for the harvesting of silk, also known as silk farming). For example, the domesticated variety shows nowadays a series of human-preferred traits such as faster growth, bigger cocoons and increased resistance to disease than the wild variety. Silk production is of great economical importance, especially in rural areas of the main producing countries, China and India, and research in these animals is expected to lead to an important increase in revenues. In addition, these are good model organisms for studies in invertebrates, as they easy to breed and have fast growth. Now, a team comprising scientists from various Institutes in China has asked the question: which are the main differences found in domesticated silkworms, apart from genetic divergences, that contribute to their particular characteristics?
Nature Magazine has again provided us with plenty of food for thought.
One particular article from the admirable list of advanced online publications caught my attention not only because of the groundbreaking research, but because it reminded me that the way to applicable technology starts with basic research. This time, the focus is on optogenetics, which combines techniques as diverse as genetic manipulation and the use of light.
More than genetic engineering, what optogenetics does is to control live organisms in real time make with the use of light-sensitive proteins. This is science fiction happening now.
Check here the original article at Nature’s site. And to better understand optogenetics, read our colleagues’ post at the Brain Bank, one of our favorites at ScienceBlogs.com
It is a truth not difficult to prove that science is an important part of our lives. We don’t have to look too far to detect its clear influence. But how much do we care about it?
We are surrounded by science and its products in our houses, working places and even when we go on holidays. It is part of the simplest things we do everyday, from ourpersonal hygiene to the food we eat. Without science, our routines would be unrecognizable. So we must be dedicating a good share of our attention to science. Are we?
