- It happens the same everywhere around the world. (The Yard)

-I was invited somwhere in the wold, by a friend, my friend make a lot of promisses. Promises which prefer to forget, now. He live in a house with several apartaments, with a shared courtyard. Since I am hosted here, and waith the promises come true, I see the same general dirt in the yard. - Time passes by working better. I said, and I grabbed with enthusiasm to clean. Gathering dried laves, collecting papers, sweep. A Lady , neighbour Lady, asked me, very surprised what I doing there . - Cleaning the yadr. I answered. - Because we get a lot of dirt in the house. - Yes she sayd. And she explained that the man who is responsable with cleaning dose not do his job. The inhabitants of the house will make a meeting, and they will solve the problem. This very ugly problem . - OK. I said, she left. While I cleaning the yard, I think what will happen now ? The man will be judjed, they will fire him . However, it is his duty. Or not ? I have collected numerous remnants of cigarettes, Ice cream papers, ...... Did we not have to respect the work of others ? - I asked myself. Why ?. 

- Maybe the man can not chase after everyone. And it looked like in the yard, is a competition. - Who throw more rubbish. It is easy to criticize, it is harder to help. For example: - do not throw trash in the yard. But, it is easier to judge . - This happen every day wherever in the world. We are different characters, but the same different caracters live worldwide, the only thing that is different is the country in which we live. Or where we come from. Richer country , or a poorer country. And it's good, they are poor countries, - We have forgotten how cleaning. They will do it. While I was cleaning, listening the album, The Wall (Pink Floyd and it fit well in the current situation.) I just remembered, my friend promises . - " Our home , our food , our work , life together ........." Yeah sure . Now my friend says he promised to much. In other words . Get out. Or , I 'm bored with this new toy. Thank God that we are not all the same. We are different characters. I have favorite quotes : - "Accept the things to Which fate binds you, and love the people with Whom fate brings you together , but do so with all your heart . " .... "Where I live if someone Gives you a hug it's from the heart . "...To tell the truth, I was very well tolerated in this house, I did not missed anything, for a time. Now my days are counted here, I think I've become an unwanted ghost. A sort trash. Why people do not understand, that promises must be respected. As a man's life may depend on promises. Those who are educated in the virtual world, forget the true world. - "Love all, trust a few, do wrong to none." - - I do not want to hurt anyone, especially my friends, my friend. I keep the pleasant memories. (Because it was. I was accepted and helped for a while. I must admit that. ) My friend wants to help me, even now. He'll tolerate my presence in the area. What great luck I have. Stupidity and reign are paid. I feel it now. - I continue to clean away, maybe I'll manage to clean, in my soul and in others soul. Maybe. But life will never forgive this fatal mistake, why I trusted my friend. Why ? - Because things are linked together, promise and trust. Okay, time to go, I do not accept any false help, and promises more. I'm going to clean in to another world.

O nouă tehnică de 'spionare' a obiceiurilor alimentare ale celulelor ar putea contribui la diagnosticarea timpurie a cancerelor

Oameni de ştiinţă de la Universitatea Edinburgh au creat o nouă tehnologie de imagistică pentru a vizualiza ceea ce "mănâncă" celulele vii, iar noua metodă ar putea fi utilizată pentru a ameliora diagnosticarea şi tratarea unor boli, inclusiv a cancerului, informează luni Press Association.

Cercetătorii scoţieni au dezvoltat un fel de sonde chimice, care se aprind atunci când se ataşează de anumite molecule specifice "mâncate" de celule, precum glucoza.

Autorii studiului au creat un experiment insolit, folosind embrionii transparenţi ai unor peşti, fapt care le-a permis să observe obiceiurile alimentare ale celulelor.

Ei au utilizat microscoape pentru a vedea modul în care celulele vii consumă glucoza în interiorul embrionilor vii şi transparenţi ai unor peşti-zebră.

Apoi, cercetătorii scoţieni au descoperit că tehnica lor funcţiona şi în cazul celulelor umane cultivate în laborator.

Oamenii de ştiinţă sunt de părere că noua tehnologie ar putea contribui la detectarea modificărilor minore care se produc în obiceiurile alimentare ale celulelor din interiorul corpului, permiţând medicilor să descopere bolile mult mai devreme.

Toate celulele se bazează pe glucoză şi alte molecule pentru a supravieţui, iar o modificare în obiceiurile alimentare ale celulelor poate să reprezinte un semnal de avertizare care să ateste apariţia unei boli.

Autorii studiului consideră că noua metodă de imagistică ar putea fi adaptată pentru a vizualiza şi alte molecule importante pentru sănătate şi pentru diagnosticarea maladiilor.

De asemenea, medicii ar putea utiliza noua tehnologie pentru a monitoriza felul în care pacienţii răspund la tratamente, prin urmărirea moleculelor care sunt consumate de celulele sănătoase şi de cele bolnave.

Studiul, coordonat de Marc Vendrell, profesor de imagistică biomedicală la Universitatea Edinburgh, a fost publicat în revista Angewandte Chemie.
