discovered bacterium that eats arsenic

FOUND IN MONO LAKE IN CALIFORNIA AND fed the Toxic

It was discovered a bacterium "alien" that feeds on arsenic. Not in the sense that alien from outer space, but its metabolism is not based on oxygen, hydrogen, nitrogen, phosphorus, sulfur and carbon as all other living beings on this planet, but on something that is poisonous to life in his complex. The bacterium is the strain GFAJ-1 family Halomonadaceae Gamma Proteobacteria class that lives on the bed of Mono Lake, a lake in California on the border of Yosemite Park, known for its extremely alkaline water (pH 10) containing high amounts of arsenic and salts that are deposited to form beautiful travertine concretions and locally are called tuffs, although they are not geologically.

AMENDED - The bacterium has been modified in a laboratory of the Institute of astrobiology at Arizona State University ordered by Felisa Wolfe-Simon, thanks to research funded by NASA and published Thursday by Science . Now life is completely dependent on the bacterium by a poison such as arsenic. The existence of such an organism is the proof that life can exist in forms very different from those we know, a figure which can not fail to take into account all space programs involved in the search for living beings on other planets. "The great news is that arsenic is utililzzato as a building block for an organization," said Professor Ariel Anbar, co-author of the study. Researchers have grown in laboratory bacteria found in the mud of Mono Lake with high levels of arsenic. A little 'time, biologists have increased the amount of arsenic in the culture medium for bacteria, microorganisms make up completely dependent on quell'elemento. Che i batteri siano riusciti a sopravvivere è stata una sorpresa per gli stessi ricercatori. I batteri del ceppo GFAJ-1 sono oggi l'unica forma di vita finora nota nella quale una sostanza tossica come l'arsenico sostituisce completamente il fosfato, indispensabile alle funzioni vitali di tutte le forme di vita conosciute. Il fosfato è infatti alla base delle molecole di tutte le cellule.

Applificazione the web: # FAIL!

The applificazione the web is to write applications (typically for a fee) that actually provide the exact same information that is available via the web. Since

must somehow justify the price of the application is trying to make the customer believe that the dedicated application instead of the simple website could be a better user experience. So here you are trying to give a look and feel more 'nice maybe trying to add some data or some function' absent on the Web (there is usually no more 'no technical reason that prevents to provide the same experience on the Web) .

But it's all roses, no thorns? Well maybe in some cases it can 'be so', but the rule I see in everyday experience and 'that is the opposite, namely that the app had almost all the thorns and leaves the petals web experience.

Porto two examples: the first refers to the application of the Corriere della Sera Phone for Windows 7 that worked the first week and then (at least on my end) and 'always gone systematically crash almost always already' all ' initiation of the same or just try moving from the first page. Uninstalled and put on the back burner.

The second example, instead take it from Apple and from NBA Game Time Lite and that 'an application fee (0.79 €) which has a sister even more' expensive (9.99 €) fornisce servizi ulteriori.

Ieri notte questo e' quello che vedevo tramite NBA Game Time Lite:

Le partite non risultavano ancora in corso nonostante l'ora di inizio fissata per l'1:30 (ossia da oltre un'ora, considerate le 6 ore di fuso orario).

Allora chiudo l'app e apro Safari per andare direttamente sul sito NBA.com.

L'NBA sembra "amare" molto i device Apple, per cui invece di avere un singolo sito per i device mobile, hanno fatto una versione del sito mobile specifica per iOS, molto curata nella UI, ma anch'essa profondamente bacata, infatti li' la partita risulta iniziata da un pezzo, ma appena I'm going to look at the statistics of the match what occurs?

for the Atlanta-Miami game statistics are displayed for a few days before a game between Philadelphia and Cleveland!

Then I take the LG with WP7 and opening the exact same site that I am the general UI and 'the same if I open them with the BlackBerry and' everything 'in place: lots are still running and adjusted statistics.

Morality and 'the web and applificazione' cost to the user, and 'cost for the person who carries out' cause this must be dedicated to maintenance instead of just maintaining the site and gain for Apple and 'the only one who really benefit from this insane process.

This "transformation" of the Web strongly desired by Apple and 'destructive, I hope that more and more' and those who take note that this phenomenon applificare the web is transitory.

DEPRESSION: DISCOVERY key protein molecule to cure

Scoperta una proteina che potrebbe essere la chiave per un nuovo trattamento contro la depressione, altamente mirato e con pochi effetti collaterali.

Neuroscientists at the Centre for Addiction and Mental Health (CAMH) in Toronto found that the coupling between two dopamine receptors and 'significantly more' high in the brains of people who had been diagnosed as more 'severe depression. "We have identified a potential therapeutic target for the development of novel anti-depressants," said Dr. Fang Liu, Principal Investigator and Senior Scientist in CAMH and Associate Professor of Psychiatry at the University 'of Toronto. Working on this discovery, researchers have searched for ways to disrupt this "coupling" between the two receptors in hopes of getting an effect anti-depressant. They began by analyzing a specific signaling mechanism of dopamine, the combination of D1 and D2 receptors, to identify sites that bind the two receptors together.

With this information, you were able to generate a protein that can break the bond of the two receptors.

protein and 'was then tested in animal models to compare the effects with the current anti-depressant drugs. "After administering the peptide, we have seen a marked improvement in depressive behavior. The improvement observed in the group and peptide 'was equivalent to the improvement with traditional anti-depressants. "This new protein is a completely new approach to treating depression, treatment to date is based primarily on drugs that block the serotonin transporter or norepinephrine.

These conventional antidepressant drugs do not work for all patients, and can cause various side effects.

"We are confident that our research will lead 'to new treatment options that may reduce side effects for patients with depression "said Dr. Liu.
