Scientists Just Automated Designing Light-Based Computers. Your computer ferries data around using electrons and conductive wires; for now, anyway.

Scientists Just Automated Designing Light-Based Computers

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. A influência da epopéia de Gilgamesh na escrita do Gênesis. 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.

Farming in the Sky

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. 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.

This Microscopic Beam Splitter Could Enable Light-Based Computers

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. 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.

John McAfee Defends the Security Researcher Who Hacked Airplanes Mid-Flight

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?

Google Just Made Near-Infinite Storage Cheap and Easy

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. 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.

Neuromorphic Circuits Don't Just Simulate the Brain, They Outrun It

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.

Transforming all donated blood into a universal type. 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. "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.

Renewables are abundant, but they tend to make themselves available at inconvenient times—the wind often blows strongest at night, when the lights are off—and in out-of-the-way places, like sunlight in the desert. In order to get more from renewables, we need a better storage solution than even the most advanced batteries, which aren’t likely to store anywhere near what we need or what renewables produce. So far, the main large-scale storage option is even more inconvenient than the renewables themselves. Pumped hydro storage is an ingenious, 100-year-old solution that uses no fancy science, only physics and engineering: falling water turns turbines to run a generator that produces electricity.

Organovo has been working on printing functional human tissue since being incorporated in 2007, and first printed a cellular blood vessel in 2010. Since January 2014, it has offeredbioprintedliver tissue (marketed as exVive3D™ liver tissue) for companies to use in drug trials and disease modeling, and it looks as though its bioprinted human kidney tissue will be used for the same tasks, starting sometime in the latter half of 2016. "Kidney represents an ideal extension of capabilities to 3D bioprint organ tissues that can be tremendously useful in pharmaceutical research," Keith Murphy, Organovo's chairman and CEO, said via press release.

“The product that we intend to build from these initial results can be an excellent expansion for our core customers in toxicology, who regularly express to us an interest in having better solutions for the assessment of human kidney toxicity.

SpaceX Warns Fake Competitors Could Disrupt its Space Internet Plan. ​The biggest impediment to SpaceX's plan to create a worldwide, satellite broadband network might not be the sheer technological difficulty of putting 4,000 satellites into space. Instead, outdated international and domestic regulations on satellite communications could stand in the way, according to a ​new Federal Communications Commission filing by the company. In January, SpaceX founder Elon Musk said the company plans to ​launch an array of internet-providing satellites that will orbit roughly 750 miles above the Earth, giving the company something to do with those reusable rockets it's been developing.

But, in order to launch and operate any satellite, manufacturers have to reserve communications spectrum with either the FCC or another country's communications body, which then must deal with the International Telecommunication Union.
