Just for fun.
Mathieu Lehanneur: Local River
“Local River, home storage unit for fish and greens.
The Locavores appeared in San Francisco in 2005 and define themselves as ‘a group of culinary adventurers who eat foods produced in a radius of 100 miles (160 km) around their city’. By doing so they aim to reduce impact on the environment inherent to the transport of foodstuffs, while ensuring their traceability.
Local River anticipates the growing influence of this group (the word ‘locavore’ made its first appearance in an American dictionary in 2007) by proposing a home storage unit for live freshwater fish combined with a mini vegetable patch. This DIY fish-farm-cum-kitchen-garden is based on the principle of aquaponics coupled with the exchange and interdependence of two living organisms - plants and fish.
The plants extract nutrients from the nitrate-rich dejecta of the fish. In doing so they act as a natural filter that purifies the water and maintains a vital balance for the eco-system in which the fish live. The same technique is used on large-scale pioneer aquaponics/fish-farms, which raise tilapia (a food fish from the Far East) and lettuce planted in trays floating on the surface of ponds.
Local River responds to everyday needs for fresh food that is 100% traceable. It bets on a return to favour of farm-raised freshwater fish (trout, eel, perch, carp, etc…), given the dwindling supplies of many saltwater species due to over-fishing. It also demonstrates the capacity of fish-farmers to deliver their stock live to a private consumer as a guarantee of optimum freshness - impossible in the case of saltwater fish that has been netted.
Local River aims to replace the decorative ‘TV aquarium’ by an equally decorative but also functional ‘refrigerator-aquarium’. In this scenario, fish and greens cohabit for a short time in a home storage unit before being eaten by their keepers, the end-players in an exchange cycle within a controlled ecosystem.”
Bacteriograms the brightly-colored images that are more like photograms, and not so much like photographs were made by collecting bacteria samples from Artist Erno Erik Raitanen own body, and cultivating the bacteria samples on photographic film.
Tens of thousands apply for one-way trip to Mars.
Mars One opened applications for their Astronaut Selection Program two weeks ago, with hopes to start sending humans one-way to Mars in 2023.
The company has revealed that 78,000 people from over 120 countries have already applied. Applications are still being accepted for another three months, here.
It’s been 17 years since Dolly the sheep was cloned from a mammary cell. And now scientists applied the same technique to make the first embryonic stem cell lines from human skin cells.
Ever since Ian Wilmut, an unassuming embryologist working at the Roslin Institute just outside of Edinburgh stunned the world by cloning the first mammal, Dolly, scientists have been asking – could humans be cloned in the same way? Putting aside the ethical challenges the question raised, the query turned out to involve more wishful thinking than scientific success. Despite the fact that dozens of other species have been cloned using the technique, called nuclear transfer, human cells have remained stubbornly resistant to the process.
Until now. Shoukhrat Mitalipov, a professor at Oregon Health & Science University and his colleagues report in the journal Cell that they have successfully reprogrammed human skin cells back to their embryonic state. The purpose of the study, however, was not to generate human clones but to produce lines of embryonic stem cells. These can develop into muscle, nerve, or other cells that make up the body’s tissues. The process, he says, took only a few months, a surprisingly short period to reach such an important milestone.
Nuclear transfer involves inserting a fully developed cell – in Mitalipov’s study, the cells came from the skin of fetuses – into the nucleus of an egg, and then manipulating the egg to start dividing, a process that normally only occurs after it has been fertilized by a sperm. After several days, the ball of cells that results contains a blanket of embryonic stem cells endowed with the genetic material of the donor skin cell, which have the ability to generate every cell type from that donor. In Dolly’s case, those cells were allowed to continue developing into an embryo that was then transferred to a ewe to produce a cloned sheep. But Mitalipov says his process with the human cells isn’t designed to generate a human clone, but rather just to create the embryonic stem cells. These could then be manipulated to create heart, nerve or other cells that can repair or treat disease.
“I think this is a really important advance,” says Dieter Egli, an investigator at the New York Stem Cell Foundation. “I have a very high confidence that versions of this technique will work very well; it’s something that the field has been waiting for.” Egli is among the handful of scientists who have been working to perfect the technique with human cells and in 2011, succeeded in producing human stem cells, but with double the number of chromosomes. In 2004, Woo Suk Hwang, a veterinary scientist at Seoul National University, claimed to have succeeded in achieving the feat, but later admitted to faking the data. Instead of generating embryonic stem cell lines via nuclear transfer, Hwang’s group produced the stem cells from days-old embryos, a technique that had already been established by James Thomson at University of Wisconsin in 1998.
