The RMS Titanic, which hit an iceberg and sank in 1912 and then was found by searchers in 1977, still has a few mysteries left.
A brand-new bacterial species dubbed Halomonas titanicae by scientists from Dalhousie University in Halifax and the University of Sevilla, was found aboard the Titanic and is contributing to its deterioration.
The researchers isolated the Halomonas titanicae micro-organisms from a 'rusticle' collected from the Titanic, 3.8 km below the ocean surface.
DNA computing and storage has been on the horizon for most of this decade but never gone beyond the intellectual exercise stage. Storage limitations were far too small to merit applied science efforts so it was clever but that was the extent of it.
That may not be the situation for much longer. GenomeWeb reports
that a research team from the Chinese University of Hong Kong has encrypted and stored a hefty 90GB of data in one gram of bacteria, creating what they are calling a "massively parallel bacterial storage system."

Bacteria that we carry in our bodies may help decide who we marry, according to a new study that analyzes the gut of...a small fruit fly.
A group of molecular biologists recently demonstrated that the symbiotic bacteria inside a fruit fly greatly influence its choice of mates. They propose that the basic unit of natural selection is not the individual living organism, plant or animal, but rather a larger biological milieu called a holobiont. This milieu can include plant or animal life as well as their symbiotic partners. In the case of animals, these partners tend to be microorganisms like intestinal bacteria.
On Thanksgiving Day, it will be all hugs and football for many people, but inside their mouths one of the biggest wars of the year will be taking place.Streptococcus mutans and other harmful bacteria get their own holiday feast and S. mutans gets to launch one of its biggest assaults of the year on your tooth enamel. But you have soldiers on your side too, namely cranberries and even wine, say dental researchers at the University of Rochester Medical Center
Many bacteria spend much of their existence within a matrix that they create, called biofilm. Biofilm consists of mucopolysaccharide (or slime-like, think “The Blob” from the 1950s) structures produced by microorganisms as a defense mechanism against their environment.
Oil fields are highly specific ecosystems - they contain no oxygen and the temperature, pressure and salinity are often high, which makes them home to a very particular community of bacteria.
Geert van der Kraan, a doctoral student who received his Ph.D. from TU Delft on the subject, says using bacterial changes as a biomonitoring tool in oil fields can be a way of keeping tabs on the state of the oil field itself - and increase its yield.
Quick, what's the world's favorite beverage?
If you said 'beer', you're wrong, water and tea are way ahead, but it means the most comprehensive deciphering of the beer's proteome (the set of proteins that make beer "beer") ever reported will interest you just the same. Their report on the beer proteome could give brewers a new way to engineer and even customize the flavor and aroma of beer by experimenting with the proteinaceous components.
Beer is the world's favorite alcoholic beverage, so you needn't feel bad about your beverage answer.
Tuberculosis (TB) is a contagious disease of the lungs and other organs caused by Mycobacterium tuberculosis (or M. tuberculosis) and which infects roughly a third of the world's population. 5-10% of those in the infected population become sick or infectious at some point during their lifetime.
One thing I see a lot of, given the kind of community we are and so the kinds of people I read to see what's happening in the rest of the world, is how things have to change
