Sicer zelo lepo odkritje, ampak sem mnenja, da je malce preuranjeno govoriti o novem antibiotiku. Predkličničnih študij (na miših) je bilo zaenkrat namreč zelo malo, da o testih na ljudeh sploh ne govorim. Po mehanizmu delovanje je tale teixobactin podoben nekaterim že znanim antibiotikom (vezava na lipid II, ki je prekurzor v biosintezi celične stene bakterij), na katere se je potem rezistenca razvila (vankomicin, lantibiotiki, manopeptimicini, ramoplanin). Srčno upam, da teixobactin ne bo deležen iste usode kasneje... Molekula ima še par drugih problemov, ki lahko malce zaustavijo njen razvoj oziroma vpliv, ki bi ga imela v boju proti rezistenci; izmed teh velja izpostaviti dejstvo, da deluje le na po Gramu pozitivne bakterije. Dandanes so veliko večji problem infekcije, ki jih povzročajo po G- bakterije. Dodatno težavo predstavljajo fizikalno-kemijske lastnosti spojine, ker je strukturna formula takšna, da bo verjetno možna le intravenska aplikacija, saj bo biološka uporabnost zaradi makrociklične in peptidne strukture nizka.

Kolikor sem jaz prebral tale članke, objavljen v Nature, je bolj pomembno odkritje način, kako so prišli do te spojine. Namreč, z nekim čipom so uspeli gojiti bakterije, za katere velja, da jih je težko gojiti v kulturi. Tako izkoriščajo mehanizme bakterijske neribosomalne sinteze peptidov, ki jih nato izolirajo iz medija, kjer bakterije rastejo. Tako je bazen potencialnih novih (in dosedaj povem neznanih) spojin, ki jih bodo uspeli izolirati v prihodnosti ogromen.

Pa še ena stvar, ki me moti ob poročanju takšnih stvari: ne gre za edini nov antibiotik v zadnjih 30 letih. Od leta 2000 je na tržišče prišlo 5 protibakterijskih učinkovin z novim mehanizmom delovanja (sem seveda ne spadajo nove generacije cefalosporinov), in sicer linezolid, daptomicin, retapamulin, fidaksomicin in bedakvilin). Je pa dejstvo, da je tudi to premalo v boju proti rezistenci.

Scientists at the University of Rochester have created a metal that is so extremely hydrophobic that the water bounces on it as if it were repelled by a magic force field. Instead of using chemical coatings they used lasers to etch a nanostructure on the metal itself. It will not wear off, like current less effective methods.

Jan Ov Plain wrote: Google a step closer to developing machines with human-like intelligence Professor Geoff Hinton, who was hired by Google two years ago to help develop intelligent operating systems, said that the company is on the brink of developing algorithms with the capacity for logic, natural conversation and even flirtation. Although the work is at an early stage, he said there is a plausible path from the current software to a more sophisticated version that would have something approaching human-like capacity for reasoning and logic. “Basically, they’ll have common sense.” Hinton, who is due to give a talk at the Royal Society in London on Friday, believes that the “thought vector” approach will help crack two of the central challenges in artificial intelligence: mastering natural, conversational language, and the ability to make leaps of logic. “It’s not that far-fetched,” Hinton said. “I don’t see why it shouldn’t be like a friend. I don’t see why you shouldn’t grow quite attached to them.” Nori časi prihajajo.:) Kakšen bo že job market čez 20,30 let? Kaj kurec bomo ljudje sploh delal?

A team of physicists led by Caltech's David Hsieh has discovered an unusual form of matter--not a conventional metal, insulator, or magnet, for example, but something entirely different. This phase, characterized by an unusual ordering of electrons, offers possibilities for new electronic device functionalities and could hold the solution to a long-standing mystery in condensed matter physics having to do with high-temperature superconductivity--the ability for some materials to conduct electricity without resistance, even at "high" temperatures approaching -100 degrees Celsius.
