Skynet is born.

Investigación y Desarrollo via ScienceDaily:

Drones say goodbye to pilots. With the goal of achieving autonomous flight of these aerial vehicles, the researcher José Martínez Carranza from the National Institute of Astrophysics, Optics and Electronics (INAOE) in Mexico, developed a vision and learning system to control and navigate them without relying on a GPS signal or trained personnel.

Mexican José Martínez, structured an innovative method to estimate the position and orientation of the vehicle, allowing it to recognize its environment, hence to replace the GPS location system for low-cost sensors such as accelerometers, gyroscopes and camcorders.

The main idea was to avoid the use of GPS and opted for the use of video cameras on board of the vehicle for visual information and applying an algorithm to locate and orient the drone during its flight to use such information.

Philosophy Recap: Darwinism

via The Stanford Encyclopedia of Philosophy:

Darwinism designates a distinctive form of evolutionary explanation for the history and diversity of life on earth. Its original formulation is provided in the first edition of On the Origin of Species in 1859. This entry first formulates ‘Darwin’s Darwinism’ in terms of five philosophically distinctive themes: (i) probability and chance, (ii) the nature, power and scope of selection, (iii) adaptation and teleology, (iv) nominalism vs. essentialism about species and (v) the tempo and mode of evolutionary change. Both Darwin and his critics recognized that his approach to evolution was distinctive on each of these topics, and it remains true that, though Darwinism has developed in many ways unforeseen by Darwin, its proponents and critics continue to differentiate it from other approaches in evolutionary biology by focusing on these themes. This point is illustrated in the second half of the entry by looking at current debates in the philosophy of evolutionary biology on these five themes.

DIY prosthetics: the extreme athlete who built a new knee

493px-Drenwkolaniedzien5
Brian Bartlett lost his leg at 24. Rose Eveleth hears how a man who just wanted to ski again invented a new kind of knee.

When Brian Bartlett was 24 he was hit by a car from behind so hard it ripped his right leg off instantly. It all happened so fast. He doesn’t like to talk about it. “You really can’t understand,” he told me. “There’s just no way to…until you have an injury where you’re ripped or cut apart instantly.”

He turned 25 in the hospital. When he left, fitted above the knee with a prosthetic leg, he wanted to return to his life. Before the accident, Brian had been a competitive skier; he had a sponsorship, and he was on track for the US Olympic team. So after the accident, he was eager to get back to the slopes. It was 1998, long before Oscar Pistorius would take the track at the Olympics or Amy Purdy would take the stage on Dancing with the Stars.… Read the rest

Next Jobs Automation Will Kill

Barb Darrow via Forbes:

Most of us watched as automation displaced factory workers and other laborers; but now many “skilled” workers are getting anxious as the robot overlords come for us.

When automated factories started erasing jobs at manufacturing companies, most of us shrugged: Great, better products cheaper, was the general line of thinking

But as automation keeps creeping up the stack, taking over more of what most would call “skilled” positions, well that’s getting some folks—who consider themselves skilled professionals—nervous.

Take airplane pilots for example. That’s now a dead-end job according to Mary “Missy” Cummings, director of the Humans and Autonomy Lab (HAL) at Duke University (and a former Naval fighter pilot.) She said that “in all honesty” she could not recommend that anyone become a commercial airline pilot going forward, given the current state of the art.

“Commercial pilots today touch the stick for three to seven minutes per flight—and that’s on a tough day,” she told an audience at the MIT CIO Symposium on Wednesday.

Lancet Editor: ‘The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue.’

Dr. Richard Horton, Editor in Chief, the Lancet.

Dr. Richard Horton, Editor in Chief, the Lancet.

The Lancet is one of – if the not the – most prestigious medical science journals, so when its editor-in-chief writes that “The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue,” you know that something’s rotten in Denmark. Collective Evolution reports on Richard Horton’s pronouncement:

In the past few years more professionals have come forward to share a truth that, for many people, proves difficult to swallow. One such authority is Dr. Richard Horton, the current editor-in-chief of the Lancet – considered to be one of the most well respected peer-reviewed medical journals in the world.

Dr. Horton recently published a statement declaring that a lot of published research is in fact unreliable at best, if not completely false.

“The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue.

RITHIKA MERCHANT- Mosaics of Myths

port2

RITHIKA MERCHANT

Rithika Merchant (1986) deals with creating mosaics of myths that question received histories that are available to us throughout culture. An inherent feminism exists in her decoration undermining the minimalism of modernity that views a woman just as a muse.

In 2008 she graduated with a Bachelors in Fine Arts from Parsons the New School for Design in New York. She has studied painting and conceptual practice at the Hellenic International Studies In The Arts in Paros, Greece. In 2008 she was a resident at the Convento Sao Francisco Mertola in Mertola, Portugal.
