A team of South Korean scientists on Sunday claimed to have created a ``cellular fountain of youth,’’ or a small molecule, which enables human cells to avoid aging and dying.

The team, headed by Prof. Kim Tae-kook at the Korea Advanced Institute of Science and Technology, argued the newly-synthesized molecule, named CGK733, can even make cells younger.

The findings were featured by the Britain-based Nature Chemical Biology online early today and will be printed as a cover story in the journal’s offline edition early next month.

``All cells face an inevitable death as they age. On this path, cells became lethargic and in the end stop dividing but we witnessed that CGK733 can block the process,’’ Kim said.

``We also found the synthetic compound can reverse aging, by revitalizing already-lethargic cells. Theoretically, this can give youth to the elderly via rejuvenating cells,’’ the 41-year-old said.

Kim expected that the CGK733-empowered drugs that keep cells youthful far beyond their normal life span would be commercialized in less than 10 years.

Other researchers here heaped praises on the discovery but they were cautious about the practical therapeutic application of the new substance.

``Obviously, it is an innovative finding. But we need to see whether or not CGK733 could really rejuvenate cells inside human bodies without generating side effects,’’ Prof. Kim Sung-hoon at Seoul National University said.

Prof. Kim Tae-kook, however, is confident about the commercial viability of CGK733, believing the efficiency of the material was created using state-of-the-art magnetic nano-probe technology.

``We have the magnet-associated technology to identify molecular targets inside living cells, which allowed us to examine the mechanisms of CGK733 directly,’’ Kim said.

``Unlike other research teams that must make candidates materials for drugs without being able to see their intra-cell activities, we know the precise mechanism of CGK733. So we have the better chance of making a success of the substance,’’ he continued.

Indeed, Kim basked in global recognition last June when he and his associates developed a technology dubbed MAGIC, short for magnetism-based interactive capture.

MAGIC uses fluorescent materials to check whether any drug can mix with targeted proteins inside the cell. The results were globally recognized by being printed by the U.S.-based journal Science at the time.

``MAGIC is kind of a source technology to see inside cells. Based on the method, we also found a pair of promising substances that can deal with cancers,’’ Kim said.

Na celiskom nivou tj. na pojedinacnim celijama ok...
ali cisto sumnjam da ce to uspeti kod komplikovanijih organizama...
bar u skorije vreme...
a ako to ikad uspe... totalno smo najebali

nego šta nego najebali

elem,
bio on pronađen ili ne,znam da ga ne bih kušala.

Ni ja ne znam da li je ovo dobra ili losa vijest?
Ne da vjerujem u tacnos ili rezultate iste, nego jednsotavno sto nije prirodno.
I samim tim se naglasava ideja protiv vjere u Boga a bome i nauke.

I ko hoce da zivi vjecno?

Posredi je istrazivanje koje bi se moglo smatrati svrhom celokupne dosadasnje nauke!Zaustavljanje bioloske evolucije i konacna pobeda nad prirodom!

Kao sto je poznato,starenje nije nikakav neumitni prirodni zakon,vec resenje koje je nuzni uslov evolucije u uslovima nedovoljno visoke koncentracije biotickih i abiotickih eliminacionih faktora koji bi sprecili nekontrolisano sirenje neke biljne ili zivotinjske populacije sto bi u konacnom ishodu dovelo do njenog nestanka.

Naime,za tu svrhu evolucija je odabrala posebne unutarcelijske strukture-telomere,cije skracivanje prilikom svake deobe vremenom dovodi do potpunog zaustavljanja periodicnog obnavljanja telesnih tkiva.

Glas Razuma,
Ali starenje jeste neumitni prirodni zakon...

Starenje je prirodni-evolucioni zakon,ali ne neumitan,nuzan i nepromenljiv poput recimo neunistivosti materije ili algebarskih pravila,naprotiv,izvesno je da fiziologija bioloskih sistema moze biti radikalno izmenjena vestackim putem upravo zbog svoje izvanredne slozenosti.

Jos jedna od gluposti koja se moze procitati na internetu, dzabe sam potrosio 10 min svog zivota

Ne znam da li je glupost, ali ja bih voleo da živim večno, ne znam za vas.

Strah od grobne rake!

Uvek su se pojavljivali kojekakvi manipulanti koji "Eto, baš tebi!" nude večni život, u kombinaciji sa sexom, parama i vlašću. Sad imamo zaista nauku koja je puno postigla i bitno olakšala ljudski život, pa se na to realno dostignuće kalemi priča o "naučno" dobijenom eliksiru mladosti, koji eto "tebi odabranom" nude u okviru neke "izuzetno moćne" organizacije. Na čemu se npr uopšte temeljila komunistička parola o "žrtvovanju za bolje sutra" kad to "bolje sutra" nećeš doživeti... itd  itd ...  ... ...
