How an algorithm may decide your career

Posted by in categories: computing, employment, information science

WANT a job with a successful multinational? You will face lots of competition. Two years ago Goldman Sachs received a quarter of a million applications from students and graduates. Those are not just daunting odds for jobhunters; they are a practical problem for companies. If a team of five Goldman human-resources staff, working 12 hours every day, including weekends, spent five minutes on each application, they would take nearly a year to complete the task of sifting through the pile.

Little wonder that most large firms use a computer program, or algorithm, when it comes to screening candidates seeking junior jobs. And that means applicants would benefit from knowing exactly what the algorithms are looking for.

Nanomaterials that mimic nerve impulses (spikes) discovered

Posted by in categories: computing, nanotechnology, neuroscience

Nanomaterials that mimic nerve impulses (credit: Osaka University)

A combination of nanomaterials that can mimic nerve impulses (“spikes”) in the brain have been discovered by researchers at Kyushu Institute of Technology and Osaka University in Japan.

Current “neuromorphic” (brain-like) chips (such as IBM’s neurosynaptic TrueNorth) and circuits (such as those based on the NVIDIA GPGPU, or general purpose graphical processing unit) are devices based on complex circuits that emulate only one part of the brain’s mechanisms: the learning ability of synapses (which connect neurons together).

Satellite startups turn to reinventing broadband, mapping and other industries

Posted by in categories: computing, mapping, mobile phones, satellites

Smartphones have disrupted transportation, payments and communication. But the underlying technology has tangentially changed a completely different sector: satellites.

The advances made in miniaturizing technologies that put a computer in your pocket — cameras, batteries, processors, radio antennas — have also made it easier and cheaper for entrepreneurs to launch matter into space. And investors are taking notice.

The chart below shows worldwide venture and PE investment in satellite technology companies.

How to build synthetic DNA and send it across the internet

Posted by in categories: biotech/medical, computing, internet

Biologist Dan Gibson edits and programs DNA, just like coders program a computer. But his “code” creates life, giving scientists the power to convert digital information into biological material like proteins and vaccines. Now he’s on to a new project: “biological transportation,” which holds the promise of beaming new medicines across the globe over the internet. Learn more about how this technology could change the way we respond to disease outbreaks and enable us to download personalized prescriptions in our homes.

New DNA Synthesis Method Could Soon Build a Genome in a Day

Posted by in categories: bioengineering, biotech/medical, computing

Synthetic biologists are the computer programmers of biology. Their code? DNA.

The whole enterprise sounds fantastical: you insert new snippets of DNA code—in the form of a chain of A, T, C, G letters—into an organism, and bam! Suddenly you have bacteria that can make anti-malaria drugs or cells that can solve complicated logic problems like a computer.

Except it’s not that simple. The basis of synthetic biology is DNA—often a lot of it, in the form of many genes. Making an average gene from scratch costs several hundreds of dollars and weeks of time. Imagine a programmer taking a month to type a new line of code, and you’ll likely understand a synthetic biologist’s frustration.

CERN chip enables first 3D color X-ray images of the human body

Posted by in categories: biotech/medical, computing, space

Medical X-ray scans have long been stuck in the black-and-white, silent-movie era. Sure, the contrast helps doctors spot breaks and fractures in bones, but more detail could help pinpoint other problems. Now, a company from New Zealand has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft tissue, thanks to a sensor chip developed at CERN for use in the Large Hadron Collider.

Mars Bioimaging, the company behind the new scanner, describes the leap as similar to that of black-and-white to color photography. In traditional CT scans, X-rays are beamed through tissue and their intensity is measured on the other side. Since denser materials like bone attenuate (weaken the energy) of X-rays more than soft tissue does, their shape becomes clear as a flat, monochrome image.

The reason thousands of Swedish people are inserting microchips into themselves

Posted by in categories: bioengineering, computing

Thousands of people in Sweden have inserted microchips, which can function as contactless credit cards, key cards, and even rail cards, into their bodies. Once the chip is underneath your skin, there is no longer any need to worry about misplacing a card or carrying a heavy wallet. But for many people, the idea of carrying a microchip in their body feels more dystopian than practical.

Some have suggested that Sweden’s strong welfare state may be the cause of this recent trend. But actually, the factors behind why roughly 3,500 Swedes have had microchips implanted in them are more complex than you might expect. This phenomenon reflects Sweden’s unique biohacking scene. If you look underneath the surface, Sweden’s love affair with all things digital goes much deeper than these microchips.

Semiconductor quantum transistor opens the door for photon-based computing

Posted by in categories: computing, mobile phones, particle physics, quantum physics

Transistors are tiny switches that form the bedrock of modern computing; billions of them route electrical signals around inside a smartphone, for instance.

Quantum computers will need analogous hardware to manipulate quantum information. But the design constraints for this new technology are stringent, and today’s most advanced processors can’t be repurposed as quantum devices. That’s because quantum information carriers, dubbed qubits, have to follow different rules laid out by quantum physics.

Scientists can use many kinds of quantum particles as qubits, even the photons that make up . Photons have added appeal because they can swiftly shuttle information over long distances, and they are compatible with fabricated chips. However, making a quantum transistor triggered by light has been challenging because it requires that the photons interact with each other, something that doesn’t ordinarily happen on its own.

Implanting diamonds with flaws offers key technology for quantum communications

Posted by in categories: computing, particle physics, quantum physics

Diamonds are prized for their purity, but their flaws might hold the key to a new type of highly secure communications.

Princeton University researchers are using to help create a communication network that relies on a property of subatomic particles known as their quantum state. Researchers believe such quantum information networks would be extremely secure and could also allow new quantum computers to work together to complete problems that are currently unsolvable. But scientists currently designing these networks face several challenges, including how to preserve fragile quantum information over long distances.

Now, researchers have arrived at a possible solution using synthetic diamonds.
