Philippine Consulate in New York Urges Filipino-Americans to Vote for Ramiele Malubay
Virus Newton: deja con cara de WTF a tus amigos
Ubuntu 7.10 sale imbatido en el PWN2OWN 2008
El otro d�a coment�bamos que el MacBook Air fue hackeado en el concurso "PWN to OWN" en solo 2 minutos aprovechando seg�n parece alg�n bug de seguridad de Safari. El siguiente en caer ha sido Windows Vista.
Tal y como dec�amos en el post anterior el �ltimo d�a del concurso permitieron a los participantes aprovechar vulnerabilidades de aplicaciones de terceros. Fue entonces cuando Shane Macaulay consigui� comprometer al equipo que corr�a el Windows Vista aprovechando un exploit que tiene como responsable al Flash de Adobe.
Finalmente, la port�til Sony Vaio corriendo Ubuntu 7.10 fue la victoriosa del evento, dado que nadie pudo explotar una vulnerabilidad de forma satisfactoria ni siquiera utilizando software de terceros.
En estos momentos Apple ya estar�a trabajando para parchear la vulnerabilidad que dej� en tela de juicio a su tan querido MacBook Air
Seg�n LinuxWorld en el concurso alg�n participante conoc�a la forma de comprometer a la maquina con Ubuntu, pero al parecer ninguno se sent� a desarrollar el exploit.
�Es posible que el respeto por linux de parte de la comunidad hacker haya influido de alguna forma en el desarrollo del PWN to OWN?
Ubuntu 8.04 Beta
Para aquellos que no puedan esperar, ya est� disponible para descarga la beta del nuevo Ubuntu 8.04, que ser� la segunda versi�n de Ubuntu con "Long Term Service", esto es, con soporte para los 3 pr�ximos a�os. Se puede actualizar tambi�n desde la version 7.10, as� como la 6.06 LTS. Aqu�, la lista de novedades desde la �ltima versi�n, con la inclusi�n de Gnome 2.22 y Xorg 7.3 a la cabeza. Tambi�n est� disponible el nuevo Kubuntu, que est� vez ha sido dividido en en dos sub-sabores dependiendo de que se quiera un KDE estable (3.5.9 en este caso) o la �ltima versi�n de este escritorio, la 4.0, pero con menos garant�as de estabilidad.
Z3, el primer ordenador de la historia moderna
Berl�n, 22 de junio de 1910. Ese d�a naci� Konrad Zuse, un chico al que la historia le ten�a preparado un papel trascendental en el devenir de la computaci�n moderna. Graduado como ingeniero civil en la Universidad T�cnica de Berl�n en 1935, para sacarse la carrera tuvo que realizar una gran cantidad de c�lculos a mano, algo que encontraba aburrido, por lo que comenz� a idear una m�quina que fuera capaz de llevar a cabo este tipo de operaciones de manera autom�tica.
Tras acabar su etapa universitaria entr� a trabajar en la empresa Henschel & Sohn pero un a�o m�s tarde dej� su empleo para empezar a construir la m�quina programable con la que llevaba so�ando desde su �poca de estudiante.
Sus esfuerzos se vieron recompensados cuando en 1936 cre� la primera calculadora mec�nica binaria de programabilidad limitada que le�a las instrucciones desde una cinta perforada y funcionaba con electricidad. Su nombre: Z1. A pesar de que nunca acab� de funcionar correctamente por la mala calidad de los materiales empleados en su construcci�n, sent� las bases de los futuros proyectos de Zuse.
Con la llegada de la Segunda Guerra Mundial, Zuse fue llamado a filas, pero se libr� de acudir al frente a cambio de utilizar sus conocimientos para desarrollar nuevas computadoras m�s potentes y funcionales. As�, y tras conseguir el apoyo del Aerodynamische Versuchsanstalt (algo as� como Instituto de Investigaciones Aerodin�micas), en 1939 termin� el dise�o y construcci�n de una versi�n mejorada de la Z1 que incorporaba circuitos el�ctricos con rel�s a la que llam�, c�mo no, Z2.
A partir de ese momento, Zuse comenz� a dise�ar un nuevo prototipo que vio finalmente la luz el 12 mayo de 1941. Bautizado como Z3, ha pasado a los anales de la historia moderna como el primer ordenador programable y completamente autom�tico del que se tiene constancia. Contaba con 2.000 rel�s, ten�a una frecuencia de reloj de entre 5 y 10 Hz, una longitud de palabra de 22 bits y realizaba los c�lculos con aritm�tica en coma flotante puramente binaria.
El Z3 utilizaba una cinta externa para almacenar los programas con los que trabajaba y, a pesar de que no dispon�a de ninguna instrucci�n de salto condicional, se pod�an construir bucles y llevar a cabo tareas y c�lculos que resultaban muy complejos para la �poca de la que estamos hablando.
Desgraciadamente, esta joya de la computaci�n fue destruida en 1944 durante un bombardeo aliado sobre Berl�n. A�n as�, existe una r�plica completamente funcional del Z3 expuesta de manera permanente en el Deutsches Museum, sito en la ciudad germana de M�nich.
3 Pinoys Make It To Australia�s "So You Think You Can Dance"
KC CONCEPCION Working on Her First Music Album
KC's participated in the whole creative process of making the album. She's proud of what the album will become.
"Maganda po 'yong feel ng album kasi gusto naming mangyari 'yong music niya��pag bumiyabiyahe kayo or long road trip��yon ang nilalagay n'yo sa CD player n'yo. Para siyang easy listening na very relaxed, very masarap pakinggan. Hindi siya bumibirit, hindi siya masyadong nag-i-impose sa listener," said KC.
So far, she has recorded about one fourth of the whole album. It will offer some originals and revivals, like a Top 40 popularized by Barbadian singer Rihanna.
"Gumawa kami ng bagong version ng �Umbrella' na very ethereal, pinatong-patungan namin ng vocals ko. Umiba 'yong tunog ng �Umbrella' dito. Ballad pa rin po siya, parang naging very mystical siya."
There are also some hit songs from the '80s and early '90s. "We also have �Just Can't Get Enough,' �80s, na ang tumugtog po don Pinikpikan. And we have ballads like �It Must Have Been Love' at marami pang iba mga Tagalog songs na surprise. One is from my favorite artist Joey Ayala, na favorite song ko from his collection."
Her mom Sharon Cuneta has listened to some of the raw tracks that KC has recorded so far. "Nasa iPod po niya [�yong songs], pero hindi pa kasi tapos. Every time naririnig namin, meron kaming gustong idagdag or bawasan. Marami pang mangyayaring mixing, so hindi pa final 'yong tracks."
What remains sure is that what KC has done in her yet-to-be-released album has pleased her mom. Says KC: "Excited siya at gusto niya 'yong mga kanta."

My Review of Angel's 6x05: "After The Fall Part 5"
Artwork by Franco Urru
Senior Partners (to Wesley, re Angel): �His blood will be on your hands, Wesley. Which is disappointing. We really wanted it on ours.�
And just when you think that things couldn�t suck even more for Wesley. He�s lost his girlfriend, his own and is now confined to being Wolfram and Hart�s bitch at their very leisure. To cap it all off, he also has to answer to them in the middle of a big battle.
Yes, the Senior Partners are none too happy with the way Wesley has been handling things in his ghostly form. It�s great that Wesley does try to stand up to them even when he�s blamed for Wolfram and Hart being destroyed again. It�s also pretty useless as the Senior Partners still hold him responsible for the entire mess.
Lorne isn�t exactly having the best time of things either by the looks of it. Wesley�s little omen about Angel dying is naturally bothering him and the fact that Wesley disappeared before elaborating on it doesn�t help matters.
Lorne�s mistrust of Wesley though is still mentioned. Does he really think that Wesley is one of the bad guys? I mean Angel was pretty mistrusting of Wesley at the start of this arc too so it�s not entirely an inconsistent thought. That being said, Lorne does go on to sympathising with his friends.
I bet he�s doing this because he doesn�t feel all that confident about Angel�s plan actually working. I also find it interesting that he raises the issue of Fred up. It�s interesting for a few reasons but for now, it�s interesting because Lorne believes that by being dead, Fred is in a lucky position. Well I know someone�s luck that is going to change by the end of this issue.
Angel on the other hand is psyching himself up for battle. Of course his method is more with keeping up the pretence that he�s a vampire by shaving and not wanting to answer certain questions. It�s a smart move I guess but maybe an actual training montage would also be an advisable move on Angel�s part too?
At least Angel is smart enough to bring his dragon along for the ride. With all the nasty creatures that he�s going to have to kill to restore peace, a dragon is exactly the kind of creature you want on your side.
Even Spike and Illyria are preparing for imminent carnage. All the scantily lady demon folk are in armour and led by Spider. Spider is thankfully kept away from Spike this issue so we get to see a focus on him and Illyria, which works out well enough.
Spike is still uncertain about war and the chances of winning. If he fails on Angel�s team, he�s got a hoard of Lords that will be baying for his blood but if he joins the Lords, then he has Angel to worry about. Illyria on the other hand is just interested in killing as many demons as she can. Such moral worries about choosing sides aren�t a massive priority to her.
Of course Angel also has three more reliable people on his team too. Connor, Nina and Gwen are all doing their own thing. Nina gets to play with some cool weaponry while Connor and Gwen also voice their own feelings about this battle. I have to say that so far, everyone is pretty negative about the outcome.
I get why though. Angel does have more enemies than allies to call to arms and there are also civilians who will suffer regardless of how this battle pans out anyway. That being said, in spite of all the doubt you are given the impression that Connor will help his father out no matter what.
With five minutes passing and all the Lords and a plethora of demons in the middle of the town, it�s actually time for this battle to commence. From a sinister perspective, the arrogance of the shark demon Lord is suitably interesting. He revels in the idea of human casualties and displays the most confidence that Angel will lose this battle.
Even Gunn and his vampire gang just look on at the imminent carnage. The vampires look interested in the idea of slaughter and eating on some of the human they will save. Gunn just looks nihilistically and just thinks it doesn�t matter who lives or dies, even though he�s willing to save human lives.
It doesn�t take long for a human to get caught in the crossfire and it�s around this time that Angel actually steps into battle. If he hadn�t Gunn might have done some demon slaying. That would�ve been nice to see. I still want to see some good in Gunn aside from his attempts to struggle with his vampire nature.
As for the poor sod that�s made an example of, well Angel manages to catch him mid air and leave him somewhere safe. Angel also goes out of his way to remind everyone that if he wins, everyone gets to go free. Glad to see Angel has confidence in his abilities, despite the limits he now has as a human.
Of course that doesn�t stop the demons from underestimating Angel. Reminding the civilians that it was Angel who got them into hell in the first place is a good way of diminishing faith but at least Angel takes responsibility in admitting his mistake as well as vowing to make amends for it.
Sadly for Angel as moving as that little speech might have been, he�s got way too many demons to fight all at once. The female Skip, some fire thing, a dinosaur and another beastie all pretty much attack him all at once. Even brandishing his sword isn�t that much of a deterrent against this lot.
As for the T-Rex, it�s funny that it�s a talking point amongst the demons. Hey, even monsters have some form of snobbery but they don�t get to be too smug for long when a bright light sends a few cars flying over. Yet another thing for Angel to kill in this big battle?
Not really as the light seems to be a signal for Wesley. Wolfram and Hart do continue to berate him but even they have to let him go when he argues about getting on with his job so to speak. With everyone else fighting, the only people to pay attention to Wesley�s return are the pink and blue haired ladies from the previous issue.
One of the things that Wesley then wants to do is get everyone together to help Angel out, who at this point is barely winning. Lorne however is one step ahead and has already sent everyone into battle with his own powers of persuasion. Good on Lorne and good for Angel, because he�s pretty useless without the gang here.
With the dragon freed by Groo and Angel receiving much needed help with Connor, Gwen and Nina, things do seem to getting better. Hell even Spike is useful when he�s not insisting on the lack of banter. Don�t be such a spoil sport � banter during fights is a Whedon trademark.
Angel�s delight at everyone pitching in to help him is rather touching as he insists that he didn�t ask for the help. Lorne also pointing out to a demon Lord that he�s got more power imaginable is also a neat way of him justifying why he chose to side with Angel in this battle. Gunn on the other hand is still watching but believes that he�s reunited the gang. Funny that he doesn�t want to be a part of that same gang then.
As for Groo, well he contributed good to this story by just freeing the dragon. The dragon then gets into battle with the T-Rex and even on this show, that�s some sight to behold. Maybe the producers of Primeval could do something like that in their next season.
Of course, Angel asking Connor and Spike why they want to help is a little distracting. Both of them mention that Lorne gave a moving speech but for Spike, there�s also another factor in his decision to help Angel out � Illyria.
Spike must�ve grown pretty damn attached to Smurf Girl because he knows there�s something up with her and he wants Angel to fix. I should be glad that he isn�t blaming Angel for whatever predicament Illyria is in and despite his reservations, Angel does agree to help Illyria out.
This however comes way too late. Illyria might be able to slaughter demons left, right and centre but her erratic behaviour takes a new height after she spots Wesley. Of all the things to happen to Illyria, the one fate I wanted was for her to revert to the real Fred. By the outcome of the last page, that�s exactly what I get.
Finally the first major transformation to happen in the comic that I�ve liked. Fred is back at long last but her return couldn�t have come at a worst time. Not only are there about five different demons behind her who could end her in a second but you can�t help but wonder if Wolfram and Hart have done to put Angel at another disadvantage. That and the fact that Wesley is dead, which means he doesn�t get to be with his lover in a physical sense.
Also in �After The Fall Part 5�
The cover I got for this issue was of Illyria and Wesley with a burning Hollywood in the background.
Senior Partners: �It was where we wanted Angel. It is a megaton of proof that everything is far from under control.�
Wesley: �So in addition to the other unwanted duties � I�m also in charge of caretaking your property.�
Both Lindsay and Eve were mentioned in this issue. I might be in a minority but I don�t really need to see either of them.
Lorne (to the women): �You sing a lot of gibberish ladies but sometimes you stumble onto a meaningful verse.�
Angel (to himself): �I should have spent the last couple of hours learning about Groo�s weapons but I can�t face hell�s champions with stubble.�
Anyone think that Spider and her girls were wearing similar armour to Buffy and Satsu in �A Beautiful Sunset�?
Illyria: �This plan is unacceptable.�
Spike: �Of course it is, to you. You�re off your nut. No offence but as the last sane man in hell, I say � no bloody way.�
Gwen: �They�re morons. What do they think is going to happen? Once Angel gets his ass kicked, they�re next. Harsh?�
Connor: �Yep. And correct.�
Is it me or Nina still be very badly drawn in this series? Her hair is also noticeably darker as well.
Flying Demon (to people): �What I mean to say is if any of you pathetic nothings spoil our kill, I�ll respond like so.�
Angel (to the people/demons): �Here I am. Again. Trying to make things right. Again. Yeah, so can we get to the battle? That would be great�.
Given that some of those demons made fairly close contact with Angel, I�m surprised none of them detected a heartbeat or breath. Then again, Angel�s probably using spells to keep that hidden.
Angel: �You�re not an innocent dupe tricked into working for an evil overlord are you?�
T-Rex: �What the hell are you? Are you high?�
Angel: �Making sure -�
Wesley: �So stop wasting everyone�s time and put me back so I can do my damn job.�
Senior Partners: �You�re already doing it, Wesley. You�re always on the clock. Very well. We now return you to your regular scheduled programming.�
Why we didn�t get to see the Senior Partner talking to Wesley here?
Spike: �Hey crazy idea. Less banter.�
Gwen: �More fighting?�
Spike: �I don�t care. Just less banter.�
Illyria (to Spike/Wesley): �Spike, find this quivering blob�s head so that I may impale it as a warning � you.�
The next arc for Issues 6, 7 and 8 is called �First Night�, set before the events of �After The Fall�.
Fred: �Wesley � you�re here.�
Anyone else really hate the �and yes, we are aware how cruel we are� thing at the end? That was worse than the WB�s �thanks� at the end of �Not Fade Away�.
Well this was exhausting but interesting. �After The Fall Part 5� finally felt like the Angel I watched for five years and is without a doubt the wittiest of the comics released so far. That being said, I hate that I am gonna to have to wait four months to get an update on Fred�s return.
Rating: 9 out of 10.

GERALD ANDERSON Chosen to Play JULIAN in the Pinoy Version of "My Girl"
Iba-iba ang pangalan na lumutang kung sino ang magiging kapareha ni Kim sa My Girl pagkatapos i-announce sa presscon ng "Dream Big Kapamilya"�to launch the new seasons of Pinoy Big Brother Teen Edition Plus at Pinoy Dream Academy�na si Kim ang gaganap bilang Jasmine na lead sa naturang Koreanovela.
Pero nilinaw ng executive at business unit head ng ABS-CBN na si Mr. Deo Endrinal sa presscon na bago pa man i-announce na si Kim na ang napili nila para sa My Girl, napagdesisyunan na rin nila that time na si Gerald ang makakapareha niya at gaganap bilang 21-year-old na si Julian. Hindi lang daw nila agad in-announce na kasama rin si Gerald sa My Girl dahil presscon nga ni Kim 'yon para sa Dream Big Kapamilya shows.
"Happy po ako siyempre and excited din ako. It's my first time kasi. Oh, I have to go through some workshop para mag-mature ang acting ko and internally na rin," sabi ni Gerald sa interview.
Sinimulan na rin daw ni Gerald na panoorin ang Korean version ng My Girl and so far, nasa seventh episode na siya.
"It's very good. I really like Julian's character. He's very strong and affectionate also," sambit ng young actor.
Sinorpresa naman si Gerald ni Kim nang umapir din ang young actress sa solo presscon ng ka-love team. Natanong tuloy si Gerald kung ano ang ireregalo niya sa nalalapit na 18th birthday ni Kim sa April 19.
"Surprise," ngiti ni Gerald. "Basta malalaman din ninyo 'yon."
Anytime now ay magsisimula na sina Gerald at Kim sa taping ng My Girl, na nakatakdang ipalabas sa May. Pero sa April, mauunang ipalabas ang isa pang show ng pares na pagbibidahan ni Claudine Barretto, ang Maligno.
"Hindi sila mag-overlap," paniniguro ni Gerald.

Rediscovering DINGDONG DANTES
YILMAZ BEKTAS Reportedly Dating 2006 Miss Universe ZULEYKA MENDOZA
Matagal-tagal na ring walang naririnig mula sa estranged Turkish husband ni Ruffa Gutierrez na si Yilmaz Bektas pagkatapos niyang bisitahin ang asawa at ang kanilang dalawang anak dito sa Pilipinas noong August 2007.
Pero ngayong linggo ay lumabas sa mga pahayagan at magazines sa Turkey, kagaya ng Hurriyet, na may bagong babaeng idini-date si Yilmaz. Ang bagong babae sa buhay ng Turkish businessman, ayon sa mga reports, ay si Zuleyka Rivera Mendoza�ang 2006 Miss Universe mula sa Puerto Rico.
Sa isang issue ng Hurriyet ay may artikulo tungkol sa relasyon nina Yilmaz at ng 20 years old na si Zuleyka. Nabanggit din ang pangalan ni Ruffa, ang 1994 Miss World 2nd Runner-up, na asawa nga ng Turkish businessman. Sa kasalukuyan ay inaayos na nina Yilmaz at Ruffa ang kanilang divorce upang mapawalang-bisa ang kanilang kasal.
Kasama rin sa naturang artikulo ang isang solo picture ni Zuleyka at dalawang litrato na magkasama sila ni Yilmaz na tila kuha sa isang party. Sa isang larawan ay parehong naninigarilyo ng tobacco sina Yilmaz at Zuleyka, samantalang sa isa naman ay tila may ibinubulong si Yilmaz kay Zuleyka habang hawak-hawak ng Turkish businessman ang leeg ng dating Miss Universe.
Pagkatapos ng kanyang reign bilang Miss Universe, susubukan naman ngayon ni Zuleyka ang mundo ng pag-arte bilang television actress. Kasama siya sa Telemundo soap opera na Dame Chocolate.
RUFFA KNOWS.
Ayon sa malalapit na kaibigan ni Ruffa, naiyak ang TV host-actress nang mabalitaang may girlfriend na si Yilmaz.
Nag-aalala ang mga kaibigan ni Ruffa na baka sa mga bagong pangyayaring ito ay magkabalikan pa ang mag-asawa. Sabi nila, ganun daw kasi talaga ang ugali ni Yilmaz. Pinapagselos lang nito si Ruffa sa pamamagitan ng pagpapakita na may iba nang babae sa buhay niya bilang pang-akit ulit sa asawa.
Kung si Yilmaz ay may bago nang minamahal, sa tingin naman ng mga kaibigan ni Ruffa, ay wala pa ring ipinapalit ang TV host-actress sa kanyang asawa ng ilang taon.
ANNABELLE IS HAPPY.
Inaamin pa nga ni Annabelle sa mga malalapit sa kanya na araw-araw niyang ipinagdadasal sa Sto. Ni�o niya na huwag nang balikan ni Ruffa si Yilmaz. At ang isang paraan na nakikita niya upang mangyari ito ay ang makahanap ng ibang pag-ibig si Yilmaz, na tila nagkaroon na ng katuparan ngayon.
Tungkol naman sa mga anak nina Ruffa at Yilmaz na sina Lorin at Venice, ayon sa malalapit na kaibigan ng TV host-actress, tila hindi na nabibigyan ni Yilmaz ng atensiyon, panahon, at suporta ang mga bata. Ayon sa mga kaibigan ni Ruffa, ito raw ang ikinalulungkot ni Ruffa.

Manic Monday steunt Tickets For Tibet
De fantastisch mooie single 'Als je ooit nog eens terug kan' wordt gezongen door Bart Van Der Weide (Racoon) en Anneke Van Giersbergen (The Gathering). De muziek wordt verzorgd door muzikanten van de Rock formatie Kane en De Zeeuwse band Blof. De single is opgenomen i.v.m het festival Tickets For Tibet dat zondag 20 april gehouden zal worden in Amsterdam en waarvan de opbrengst naar het onderdrukte land Tibet zal gaan.
De single is vanaf 7 april te downloaden via de site http://www.ticketfortibet.com De opbrengst van de single gaat geheel naar drie jonge Tibetaanse nonnen die zes jaar werden gemarteld in een Chinese gevangenis na het zingen van een protestlied tegen de Chinese overheersing van Tibet. Na een zware vlucht over de Himalaya zijn ze nu vrij. Maar door hun ernstige verwondingen kunnen ze niet werken en het ontbreekt ze aan geld voor een opleiding en medische verzorging.
'Als je ooit nog eens terug kan' is tevens de muziek tip van de week
La fotos�ntesis artificial un paso m�s cerca
Cient�ficos alemanes han logrado un paso importante en el largo camino para imitar, de forma artificial, la fotos�ntesis de los vegetales. Pudieron sintetizar un �xido de metal estable inorg�nico, lo que permite la oxidaci�n r�pida y efectiva del agua en ox�geno.
La fotos�ntesis artificial puede contribuir de una forma decisiva, a resolver los problemas energ�ticos y con respecto al cambio clim�tico. En este caso, los cient�ficos alemanes del Research Centre J�lich, est�n intentando descubrir una forma eficiente de producir hidr�geno con la ayuda de la energ�a solar.
Muchos creen que el hidr�geno es el combustible del futuro. La industria automotriz, por ejemplo, est� trabajando duro en introducir c�lulas de combustible eficientes que puedan ser utilizadas en coches, como el caso de los japoneses, u otros.
Pero el tema es que los sistemas con c�lulas de combustible pueden ser ecol�gicos realmente si los investigadores logran producir hidr�geno a partir de fuentes renovables. La fotos�ntesis artificial es una forma, ya que esta consiste en dividir el agua en sus componentes, el ox�geno por un lado y el hidr�geno por el otro. Esto con la ayuda de la luz solar. Sin duda ser�a una forma excelente de resolver el tema del hidr�geno.
Pero no es un logro sencillo. Ya vimos aqu� otros casos en que est�n probando, incluso se han logrado paneles solares que simulan una parte de la fotos�ntesis. Pero siguen habiendo muchos obst�culos. Uno de los m�s importantes es superar la formaci�n agresiva de sustancias en el proceso de oxidaci�n del agua. Las plantas lo resuelven reparando y reemplazando de forma constante su catalizador verde, o sea las hojas.
Una imitaci�n t�cnica de esto depende de catalizadores m�s estables. Eso es lo que han logrado cient�ficos del Research Centre J�lich, la Helmholtz Association y la Universidad Emory de Estados Unidos. Se trata de un grupo de �xidos de metal inorg�nico con un centro que consiste de cuatro iones de un raro metal de transici�n el rutenio, que cataliza de forma r�pida y efectiva la oxidaci�n del agua en ox�geno mientras permanece estable.
�Nuetro complejo tetrarutenio soluble en agua muestra sus efectos en soluciones acuosas que ya tienen temperatura ambiente�, dijo el profesor Paul K�gerler, del J�lich Institute, quien sintetiz� y caracteriz� al prometedor sistema con su colega el Dr. Bogdan Botar.
�Al contrario de otros catalizadores moleculares para la oxidaci�n del agua, el nuestro no contiene componentes org�nicos. Esa es la raz�n de que sea tan estable�, dijeron.
�Ahora el reto es integrar este complejo de rutenio en un sistema fotoactivo, que convierta de forma eficiente la eneg�a solar en energ�a qu�mica�, concluy� Botar.

El europeo del mill�n de a�os
Es s�lo un fragmento de mand�bula, pero ya ha puesto en duda la visi�n hasta ahora m�s aceptada sobre la evoluci�n humana del �ltimo mill�n y medio de a�os. Es un f�sil hallado en el yacimiento de la Sima del Elefante, en Atapuerca (Burgos), en junio del a�o pasado, y su importancia estriba en su edad. Con al menos 1,2 millones de a�os es el resto humano m�s antiguo del que se tiene noticia en Europa. De �l extraen los investigadores varias conclusiones. La primera, que hay presencia humana en Europa mucho antes de lo que se pensaba hasta ahora; la segunda -unida a la anterior-, que en este continente pudieron originarse no s�lo los neandertales, como se cre�a, sino tambi�n especies como el Homo antecessor, posible antepasado com�n de los neandertales y nosotros, el Homo sapiens.
"Hasta ahora se cre�a que la �nica aportaci�n de Europa a la evoluci�n humana era una especie muy inteligente pero fallida, los neandertales. Ahora vemos que pasaron muchas m�s cosas", explica Juan Luis Arsuaga, del Centro de Investigaci�n de Evoluci�n y Comportamiento Humanos y codirector de las excavaciones en Atapuerca junto con Eudald Carbonell (Institut Catal� de Paleoecologia Humana i Evolucio) y Jos� M. Berm�dez de Castro (Centro Nacional de Investigaci�n sobre Evoluci�n Humana).
Estos investigadores, junto a otros 27 firman hoy el art�culo en el que presentan su hallazgo en Nature, que le dedica adem�s la portada. El titular es: "�El primer europeo? La mand�bula que sit�a a los humanos en Espa�a hace m�s de un mill�n de a�os".
El nuevo f�sil es una "sorpresa", seg�n Arsuaga. "Cre�amos que hab�amos encontrado ya todos los f�siles humanos de Atapuerca. Y nadie esperaba hallar restos tan antiguos en Europa".
El hueso no es una mand�bula completa sino su regi�n anterior, la parte que incluye lo que en los humanos actuales es el ment�n. Conserva algunos dientes, adem�s de un segundo premolar inferior encontrado d�as antes. Se han hallado adem�s 32 �tiles de s�lex de la misma �poca. Son lascas simples, de entre 30 y 75 mil�metros. Con ellas se aprovechaba la carne de grandes herb�voros.
Las implicaciones de este hallazgo para la visi�n general de la evoluci�n humana pueden ser importantes. Tras d�cadas de debate, la teor�a m�s aceptada hoy es que los humanos aparecieron y evolucionaron en �frica, continente del que fueron emigrando en diferentes oleadas. Se considera probado que el Homo sapiens (nosotros) sali� de �frica hace menos de 100.000 a�os y se extendi� por el planeta, sustituyendo a otras especies humanas ya asentadas. Los neandertales, en Europa, fueron una de ellas (hoy est� claro tambi�n que neandertales y sapiens son especies distintas).
Pero este f�sil de 1,2 millones de a�os podr�a estar indicando que no s�lo fue �frica el lugar donde evolucionaron especies que forman parte del linaje del Homo sapiens. "Quiz�s hay que pensar que hubo otros centros de producci�n, que hubo ondas evolutivas en diferentes direcciones", se�ala Arsuaga, uno de los directores de las excavaciones.
Hasta ahora el t�tulo de primeros europeos lo ten�an f�siles tambi�n de Atapuerca, datados en 800.000 a�os. Son de la especie Homo antecessor y fueron hallados en 1994 en la Gran Dolina. Esta especie tiene rasgos antiguos pero tambi�n muy modernos; los investigadores han descrito la cara del llamado ni�o de la Gran Dolina como parecida a la nuestra, plana y gr�cil, pero su frente ten�a cejas con un reborde �seo muy robusto y sus dientes tambi�n eran muy primitivos. La opini�n de Arsuaga es que Homo antecessor es antepasado com�n nuestro y de los neandertales.
Entonces entra en escena esta mand�bula, catalogada "provisionalmente", como Homo antecessor. Eso implicar�a que "el poblamiento de Europa se produjo mucho m�s r�pido y de forma m�s continuada de lo que se cre�a hasta ahora", como escriben en Nature. Pero adem�s se refuerza la idea de que Homo antecessor apareci� en Europa, y no en �frica.
Ahora bien, si Homo antecessor es antepasado nuestro y hace al menos 1,2 millones de a�os estaba en Europa, y si el hombre moderno sali� sin duda de �frica hace menos de 100.000 millones de a�os... "Entonces obviamente el Homo antecessor tuvo que volver a �frica" y evolucionar en Europa, indica. De comprobarse, Europa habr�a aportado al esquema de la evoluci�n humana una especie integrada en nuestro linaje. Es una visi�n "distinta" de la aceptada hasta ahora, admite Arsuaga, pero "nuestro trabajo consiste en establecer relaciones entre los f�siles atendiendo primero a la morfolog�a, y despu�s a la geograf�a. Primero tenemos que saber qui�n es hijo de qui�n, y despu�s ad�nde emigraron".
PBA Star ROMMEL ADDUCUL Stricken with Cancer
Days after the Aquino family issued a statement announcing that former President Corazon "Cory" Aquino has colon cancer, comes the news that basketball superstar Rommel Adducul is suffering from nasopharyngeal cancer.
According to reports, the hardworking cager is currently undergoing chemotherapy sessions to prevent the cancer cells from spreading. Nasopharyngeal cancer is said to be rare in Western countries but common among Asians. The cancer cells develop in the nasopharynx which is the air space lying at the back of the nose and above the soft part of the palette.
Rommel, who plays for the Purefoods Giants, started exhibiting signs and symptoms of the disease during the recently concluded PBA (Philippine Basketball Association) finals where they lost to eventual champion the Sta. Lucia Realtors.
"I saw him really grasping for air and I didn't realized that one of his nostrils is already blocked," revealed Purefoods head coach Ryan Gregorio in an interview with ABS-CBN News.
Most of his teammates also noticed a prominent lump on Rommel's neck during the championship series.
Among those who learned first of Rommel's delicate condition is teammate Kirby Raymundo. "Honestly medyo naiyak ako parang pagpunta ko dito sa practice parang ang bigat, mabigat. Talagang malaking tulong siya sa team dahil siya yong center namin," said a distraught Kirby.
CALM BUT UNCERTAIN.
"Hindi ako nagwu-worry," enthused the optimistic center. "Kasi I think �pag sinabi kasing cancer life and death na, e. Pero �yong sa �kin, mababang klase lang siya na 80 percent na hindi na siya magre-recur 'pag naundergo ko �yong chemo 'tsaka radiotherapy," he added.
Rommel's therapy would sideline him for the upcoming conference. Purefoods, however, opted to keep him in the roster thus explaining Rommel's presence during team practice and scrimmages.
"Siguro next conference," he tentatively replied. "Sigurado na talaga na All-Filipino [Conference] talaga makakabalik na ako, pero itong conference na �to hopefully," he groped.
SHOWBIZ ROMANCE.
He surprised many people when he opted to join the Metropolitan Basketball Association (MBA) instead of entering the more established PBA. Despite earning criticisms, Rommel's stint in the MBA proved to be fruitful as shown by the handful of awards he reaped during his stay. He finally made his long overdue PBA debut in 2003 when he was drafted by the Barangay Ginebra Kings. The 6'6" center was also a consistent fixture in the National Team.
Other than his stellar hardcourt achievements, Rommel was thrown more in the spotlight when he had a romantic relationship with Fil-Italian actress Assunta de Rossi. After their separation, Rommel made tabloid news again when he was rumored to be dating controversial actress and TV host Kris Aquino. Kris ended up marrying Rommel's Purefoods Giants teammate James Yap in 2005.
Rommel is married to Jocelyn Cobankiat.

Photoshop Express Beta disponible
Ya est� disponible la beta de Photoshop Express, el muy esperado servicio de edici�n de im�genes online de Adobe. A primera vista, en Photoshop Express nos encontramos con un sitio construido enteramente en Flash 9 - otra cosa no era de esperar - gratuito y con dos gigas de almacenamiento para im�genes. integraci�n con Facebook, Picassa y Photobucket (nada de Flickr, aunque est� en sus planes) y unas opciones para mostrar galer�as bastante potentes visualmente.
Obviamente Photoshop Express es algo muy alejado de las prestaciones que la marca "Photoshop" nos tiene acostumbrados. De hecho juega en la liga de Picnik y otros editores de im�genes online: cortar, rotar, redimensionar, ojos rojos y algunos retoque muy b�sicos (aunque las opciones de auto correcci�n son bastante interesantes).
Sin embargo, Photoshop Express no es s�lo un editor de im�genes, quiere ser tambi�n sitio para almacenar y compartir (los dos gigas, el poder embeber im�genes, env�o por correo, mostrar galer�as...) �Qu� cabe esperar en el futuro? Pues probablemente a su crecimiento como software (opciones m�s potentes de edici�n), pero tambi�n una m�s que probable integraci�n con las herramientas de escritorio. De momento, la primera versi�n de Photoshop Express, de notable.
