+ - Will ultrasound-on-a-chip make medical imaging so cheap that anyone can do it?

Submitted by catchblue22
catchblue22 (1004569) writes "MIT Technology Review has an article describing a potentially groundbreaking invention:

A scanner the size of an iPhone that you could hold up to a person’s chest and see a vivid, moving, 3-D image of what’s inside is being developed by entrepreneur Jonathan Rothberg.

Rothberg says he has raised $100 million to create a medical imaging device that’s nearly “as cheap as a stethoscope” and will “make doctors 100 times as effective.” The technology, which according to patent documents relies on a new kind of ultrasound chip, could eventually lead to new ways to destroy cancer cells with heat, or deliver information to brain cells.

+ - Microsoft's Quantum Mechanics

Submitted by catchblue22
catchblue22 (1004569) writes "MIT Technology Review has an excellent article summarizing the current state of quantum computing. It focuses on the efforts of Microsoft and Alcatel-Lucent's Bell Labs to build stable qubits over the past few years.

In 2012, physicists in the Netherlands announced a discovery in particle physics that started chatter about a Nobel Prize. Inside a tiny rod of semiconductor crystal chilled cooler than outer space, they had caught the first glimpse of a strange particle called the Majorana fermion, finally confirming a prediction made in 1937. It was an advance seemingly unrelated to the challenges of selling office productivity software or competing with Amazon in cloud computing, but Craig Mundie, then heading Microsoft’s technology and research strategy, was delighted. The abstruse discovery—partly underwritten by Microsoft—was crucial to a project at the company aimed at making it possible to build immensely powerful computers that crunch data using quantum physics. “It was a pivotal moment,” says Mundie. “This research was guiding us toward a way of realizing one of these systems.”

+ - The Gods Strike Back: Wall Street's Risky Hubris->

Submitted by catchblue22
catchblue22 (1004569) writes "The Economist has an interesting essay that gives some perspective on our economic situation. From the article,

THE revolutionary idea that defines the boundary between modern times and the past is the mastery of risk: the notion that the future is more than a whim of the gods and that men and women are not passive before nature. So wrote Peter Bernstein in his seminal history of risk,"Against the Gods".

Wall Street quants have claimed over the past decade that they had the ability to quantify financial risk down to several decimal places. The Great Recession has shown their claims to be absurd. Wall Street's supposed mastery of risk allowed financial institutions to package risky loans as derivatives that ostensibly had definite and identifiable risk profiles. Our recent financial collapse shows the limits of our beautiful and elegant mathematical models of the economy."
