Scientists Just Automated Designing Light-Based Computers. Your computer ferries data around using electrons and conductive wires; for now, anyway. The age of electronics could soon end, maybe even within the next decade, thanks to an algorithm that can automatically design components that use light instead of electrons. Currently, sending electrons around a computer using conductive wires consumes up to an estimated 80 percent of a computer’s processing power. Basically, wires are a bottleneck when it comes to processing speed. Sending data with light, similar to fiber optics but at a micro-scale, would allow computers to process much more data, and much faster.

Although much promising work has been done in this area, a real and constant concern is the cost of building light-based components. Now, they’ve actually built components using the program, and they work. "We make hundreds of such circuits on a silicon chip in each fabrication run" “We make hundreds of such [optical] circuits on a silicon chip in each fabrication run,” Vuckovic wrote.

A influência da epopéia de Gilgamesh na escrita do Gênesis. “O passado das civilizações nada mais é que a história dos empréstimos que elas fizeram umas às outras ao longo dos séculos ...” 1. Da “corrida ao ouro bíblico” à nova historicidade das sagradas escrituras. Em meados do século XIX, após a descoberta na antiga cidade de Nínive da biblioteca do imperador assírio Assurbanípal (668-627 a.C.), o mundo redescobriu as antigas grandes civilizações da Mesopotâmia em tábuas de argila contendo escritos em sinais mais tarde denominados cuneiformes.

Civilizações estas de que até então, o pouco que se conhecia estava contido nos livros da Bíblia, em informações “escassas e pouco reveladoras, uma vez que estavam diretamente relacionadas com a história do povo hebreu”. (CORREA, 200-, p. 2). Tais descobertas deram início a uma espécie de “corrida ao ouro bíblico” que propunha evidenciar arqueológicamente as sagradas escrituras. 2. 3. 4. “A deusa então concebeu em sua mente uma imagem cuja essência era a mesma de Anu, o deus do firmamento. 5. Notas. Farming in the Sky. A couple of Octobers ago, I found myself standing on a 5,000-acre cotton crop in the outskirts of Lubbock, Texas, shoulder-to-shoulder with a third-generation cotton farmer. He swept his arm across the flat, brown horizon of his field, which was at that moment being plowed by an industrial-sized picker—a toothy machine as tall as a house and operated by one man.

The picker’s yields were being dropped into a giant pod to be delivered late that night to the local gin. And far beneath our feet, the Ogallala aquifer dwindled away at its frighteningly swift pace. When asked about this, the farmer spoke of reverse osmosis—the process of desalinating water—which he seemed to put his faith in, and which kept him unafraid of famine and permanent drought. Beyond his crop were others, belonging to other farmers, so that as far as the eye could see were brown stretches of newly harvested cotton plants. For one, the yields are smaller, but more importantly, the plants grow a whole lot taller. Apple and Google push Obama to prevent encryption backdoors. This Microscopic Beam Splitter Could Enable Light-Based Computers. The word “electronics” may become a misnomer faster than anyone expected. Computer engineers at the University of Utah have made a major breakthrough in the world of optical computing, creating a light beam splitter 50 times thinner than a human hair.

This innovation—one that various engineering teams have been chasing for years—paves the way for a new kind of computing altogether, where computers send signals within the machine using light instead of electrons. In a normal computer, information is processed using electrons that are sent down wires, which is a terribly inefficient way of doing things.

As Motherboard’s Michael Byrne wrote last year, it’s like “building subway tunnels for cockroaches.” Image: Nature Photonics With the invention of this tiny beamsplitter (which looks strangely like a QR code), light can be divided into two channels of information and transmitted on a much smaller scale. John McAfee Defends the Security Researcher Who Hacked Airplanes Mid-Flight. John McAfee, everyone's favorite fugitive and unhinged former CEO, is defending security researcher Chris Roberts, who made headlines last week after the FBI claimed he hacked into an airplane mid-flight through vulnerabilities he found in its in-flight entertainment system. According to a search warrant application, Roberts told the FBI he hacked into the control systems of Airbus and Boeing aircraft, using a modified ethernet cable to connect to a port on the Seat Electronic Box (SEB) located underneath the passenger seat.

It said that on at least one occasion, he slightly increased the thrust of the plane's right engine, causing it to veer slightly to the left. Roberts also admitted to running similar tests 15 to 20 times between 2011 and 2014, the document states. He was detained in April after he tweeted a joke about how he could hack a plane while aboard a United Airlines flight to Syracuse, New York. Bill Gates, Steve Jobs? Tudo começou no Estado! Google Just Made Near-Infinite Storage Cheap and Easy. Have an extra petabyte of data sitting around? Today the company that has already amassed a huge chunk of the world’s data has made it easier to sock away a whole lot more. This morning Google announced what it’s calling Google Cloud Storage Nearline, a cloud-based version of an old-fashioned way to store massive amounts of data too important to delete but not important enough to keep close. The service is designed for companies with very large storage requirements — on the order of hundreds of terabytes.

Traditionally, businesses that want to archive data at that scale have turned to offline or “cold” storage, meaning that the data isn’t immediately available, usually because it’s stored on tape drives or other media and filed away in a vault somewhere. That saves costs by reducing both electrical use and the number of servers that employees have to maintain. For Google, however, the main point of the service is that it might help woo more customers from Amazon.

Better Than a Jukebox. Neuromorphic Circuits Don't Just Simulate the Brain, They Outrun It. Actually simulating a human brain is a long, long way off—much longer than many neuro-enthusiasts would like us to think. But that doesn't mean powerful, practical neuromorphic computing is quite so distant. Potentially opening up a whole new avenue of neuro-sim research, scientists at the University of California, Santa Barbara published a paper this week describing the first successful attempt at building a ground-up neuromorphic circuit with the ability to complete practical tasks. To emphasize: This is not an algorithm or software model, as is usually considered within neuro-computational research, but the bare circuit itself, consisting of metal-oxide semiconductors (CMOS) and somewhat exotic components known as memristors. The result? A 100 neuron brain featuring some limited but promising visual recognition abilities.

The circuit is described in the current issue of Nature. Read more: The Incredible Challenge of Digitizing the Human Brain Image: Sonia Fernandez. Pós-proletariado, a nova classe social das ruas. Guy Standing é PhD pela Universidade de Cambridge e professor de Estudos do Desenvolvimento da Escola de Estudos Oriental e Africano da Universidade de Londres. O ex-diretor da Organização Internacional do Trabalho veio ao Brasil a convite da União Geral dos Trabalhadores e do Centro de Estudos Sindicais e de Economia do Trabalho da Unicamp para falar sobre a nova classe produzida pelo neo-liberalismo, o pós-proletariado.

Standing recorre a um neologismo, precariado (precariat em inglês) para sintetizar a dupla condição de proletários e precários dessa parcela da população. Com uma agenda de reivindicações surpreendente mesmo para governos progressistas, partidos de esquerda e sindicatos, ocupa as ruas e praças das metrópoles mundiais e se manifesta, no Brasil, nos movimentos espontâneos de rua desde junho. O autor do livro Precariado – A nova classe perigosa concedeu esta entrevista à CartaCapital: CartaCapital: O que é o pós-proletariado? GS: São três. GS: Sim. Os super-ricos e o resto. Brazil é uma distopia satírica dirigida por Terry Gilliam, em 1985. O personagem central é Sam Lowry, interpretado por Jonathan Pryce. A sociedade retratada no filme é desigual e consumista, a tecnologia é onipresente, o governo é totalitário, as corporações são poderosas e impessoais, a mãe do protagonista é obcecada por cirurgia plástica e o seu trabalho não tem sentido.

As semelhanças com as empresas e a sociedade contemporânea são notáveis. A vida imita a arte. Em um texto sobre os movimentos populares na sociedade do século XXI, Noam Chomsky traça a origem dos termos Plutonomia e Precariado. O primeiro surgiu de um estudo realizado há dez anos por analistas do Citigroup, segundo o qual o mundo está dividido em dois blocos, a Plutonomia, formada pelos super-ricos, e o resto. O objetivo dos autores era orientar os investidores a selecionar as melhores ações, aquelas de empresas que produzem para os abastados.

A nova estrutura, segundo o autor, é composta de vários grupos. Spiders Spin Super Silk After Being Spritzed with Graphene. Spiders spritzed with a carbon nanotubes or graphene particle solution were discovered by researchers in Italy to produce a stronger than usual super silk, opening up the possibility of some kickass materials hitting the market in the future. Graphene is widely touted as one of the world’s strongest artificial materials, and is made of sheets of carbon, which are just one atom thick. In the organic world, spider’s silk—which has been perfected over 400 million years of evolution—is like its natural equivalent. So Pugno decided to see what would happen when he mashed both together. "I was aiming to produce even stronger and tougher silk," lead author of a recently published study and material scientist, Nicola Pugno, told me over the phone. With a hardy team of researchers, Pugno took five spiders from the Pholcidae family and spritzed them a water and graphene particles (200 to 300 nanometres wide) solution.

Up next, Pugno and co. want to apply what this experiment to silkworms. Cientistas contestam causa humana do aquecimento global | GGN. Enviado por Adir Tavares A fraude do aquecimento global de origem antropogénica Do Resistir.info A fraude do aquecimento global de origem antropogénica continua a grassar, tanto em Portugal como no Brasil. Felizmente a comunidade científica começa a reagir à impostura propalada por políticos ignorantes que confundem clima com ambiente; banqueiros corruptos interessados no business da compra/venda de direitos de emissões de CO 2 ; pseudo-ambientalistas que fazem terrorismo climático a fim extorquir verbas; e jornalistas incultos que confundem a opinião pública repetindo como papagaios as tretas aquecimentistas.

As classes dominantes precisam inventar falsos problemas – como o do suposto aquecimento global – a fim de ocultar os verdadeiros. Chama-se a isso diversionismo.

What do you do when a patient needs a blood transfusion but you don't have their blood type in the blood bank? It's a problem that scientists have been trying to solve for years but haven't been able to find an economic solution - until now. University of British Columbia chemists and scientists in the Centre for Blood Research have created an enzyme that could potentially solve this problem.

The enzyme works by snipping off the sugars, also known as antigens, found in Type A and Type B blood, making it more like Type O. Type O blood is known as the universal donor and can be given to patients of all blood types. "We produced a mutant enzyme that is very efficient at cutting off the sugars in A and B blood, and is much more proficient at removing the subtypes of the A-antigen that the parent enzyme struggles with," said David Kwan, the lead author of the study and a postdoctoral fellow in the Department of Chemistry.

The study was published in the Journal of the American Chemical Society. "Terceirizações devem acelerar a expansão do precariado no Brasil" Economista com Ph.D. pela Universidade de Cambridge e professor de Desenvolvimento na Escola de Estudos Orientais e Africanos da Universidade de Londres, Guy Standing há tempos alerta para o fenômeno da emergência do precariado, uma nova classe trabalhadora em formação, caracterizada pela trajetória de perda de direitos que os reduz à condição de suplicantes, em um mundo marcado pela “flexibilização” das relações trabalhistas. Autor do livro O Precariado: A Nova Classe Perigosa (Editora Autêntica, 2013), ele é entusiasta de programas de renda básica, entendido como uma garantia incondicional e universal, uma vez que os antigos instrumentos de proteção da socialdemocracia trabalhista acabaram solapados pela onda neoliberal. “Se tivéssemos um novo sistema de distribuição de renda do século 21, não haveria grandes problemas com a instabilidade do trabalho.

Poderíamos inclusive absorvê-la sem transtornos”, diz, em entrevista por escrito a CartaCapital. Has the First Person to Achieve Immortality Already Been Born? Jiajing wasn’t the first or last to pursue everlasting youthfulness. It has been the stuff of legend and fantasy since we first began dreaming. Fantasy, legend, dreams—the realms of the supernatural but never the scientific.

Until now. Aubrey de Grey is a Cambridge gerontologist and co-founder or the California-based Strategies for Engineered Negligible Senescence (SENS) Research Foundation. Gerontology is the study of aging, and de Grey is currently making waves in the field. De Grey is at the epicentre of a growing cohort of researchers who believe we are on the cusp of a biological revolution which will give rise to therapies that will enable many of us already born to achieve something like Jiajing's dream.

So is immortality just around the corner? “The first thing I want to do is get rid of the use of this word immortality, because it’s enormously damaging, it is not just wrong, it is damaging,” de Grey told me. But put another way, he’s more optimistic. This Is What the Fourth Industrial Revolution Looks Like. Mind Uploading Will Replace the Need for Religion.
