Quoc Le | Innovators Under 35 | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it

While at Stanford, Le worked out a strategy that would let software learn things itself. Academics had begun to report promising but very slow results with a method known as deep learning, which uses networks of simulated neurons. Le saw how to speed it up significantly—by building simulated neural networks 100 times larger that could process thousands of times more data. It was an approach practical enough to attract the attention of Google, which hired him to test it under the guidance of the AI researcher Andrew Ng (see “A Chinese Internet Giant Starts to Dream”).

 
Sharrock's insight:

It amazes me that the idea of machine "deep learning" became public in 2012 (written 8/19/14). That's only 2 years ago! With the invention of the synapse processor chip and chips similar to this, deep learning will probably increase in terms of power, granularity, and impact on even more human-superior tasks: "The technique is now used in Google’s image search and speech-recognition software. The ultra-intelligent machine Le once imagined remains distant. But seeing his ideas make software smart enough to assist people in their everyday lives feels pretty good." Such technology will have more immediate impacts on radiology and diagnostics, as it does in the image search services, but may also increase capabilities in music and reading recommendation services. Who knows what else?

New technique creates highly accurate detailed 3D maps in real time

New technique creates highly accurate detailed 3D maps in real time | Science, Technology, and Current Futurism | Scoop.it

Computer scientists at MIT and the National University of Ireland (NUI) at Maynooth have developed a mapping algorithm that creates dense, highly detailed 3-D maps of indoor and outdoor environments in real time.

 

The researchers tested their algorithm on videos taken with a low-cost Kinect camera, including one that explores the serpentine halls and stairways of MIT’s Stata Center. Applying their mapping technique to these videos, the researchers created rich, three-dimensional maps as the camera explored its surroundings.

 

As the camera circled back to its starting point, the researchers found that after returning to a location recognized as familiar, the algorithm was able to quickly stitch images together to effectively “close the loop,” creating a continuous, realistic 3-D map in real time.

 

The technique solves a major problem in the robotic mapping community that’s known as either “loop closure” or “drift”: As a camera pans across a room or travels down a corridor, it invariably introduces slight errors in the estimated path taken. A doorway may shift a bit to the right, or a wall may appear slightly taller than it is. Over relatively long distances, these errors can compound, resulting in a disjointed map, with walls and stairways that don’t exactly line up.

 

In contrast, the new mapping technique determines how to connect a map by tracking a camera’s pose, or position in space, throughout its route. When a camera returns to a place where it’s already been, the algorithm determines which points within the 3-D map to adjust, based on the camera’s previous poses.

 

“Before the map has been corrected, it’s sort of all tangled up in itself,” says Thomas Whelan, a PhD student at NUI. “We use knowledge of where the camera’s been to untangle it. The technique we developed allows you to shift the map, so it warps and bends into place.”

 

The technique, he says, may be used to guide robots through potentially hazardous or unknown environments. Whelan’s colleague John Leonard, a professor of mechanical engineering at MIT, also envisions a more benign application.

In 2011, Emmanuel Nnaemeka Nnadi needed help to sequence some drug-resistant fungal pathogens. A PhD student studying microbiology in Nigeria, he did not have the expertise and equipment he needed. So he turned to ResearchGate, a free social-networking site for academics, and fired off a few e-mails. When he got a reply from Italian geneticist Orazio Romeo, an inter­national collaboration was born. Over the past three years, the two scientists have worked together on fungal infections in Africa, with Nnadi, now at Plateau State University in Bokkos, shipping his samples to Romeo at the University of Messina for analysis. “It has been a fruitful relationship,” says Nnadi — and they have never even met.

The Time Of Our Lives

The Time Of Our Lives | Science, Technology, and Current Futurism | Scoop.it

Living organisms evolved an internal biological clock, called the circadian rhythm, to help their bodies adapt to the daily cycle of day and night (light and dark) as the Earth rotates every 24 hours. The term "circadian" comes from the Latin words for about (circa) a day (diem).

 

Circadian rhythms are controlled by "clock genes" that code for clock proteins. The levels of these proteins rise and fall in rhythmic patterns. These oscillating biochemical signals control various functions, including when we sleep and rest, and when we are awake and active. Circadian rhythms also control body temperature, heart activity, hormone secretion, blood pressure, oxygen consumption, metabolism, and many other functions.

 

Daily cycles also regulate the levels of substances in our blood, including red blood cells, blood sugar, gases, and ions such as potassium and sodium. Our internal clocks may even influence our mood, particularly in the form of wintertime depression known as seasonal affective disorder (SAD).

 

A biological clock has three parts: a way to receive light, temperature, or other input from the environment; the protein and chemicals that make up the clock itself; and components that help the clock control the activity of other genes.

In the last few decades, scientists have discovered the genes that control internal clocks: period (per), clock (clk), cycle (cyc), timeless (tim), frequency (frq), doubletime (dbt) and others. Clock genes have been found in organisms ranging from people to mice, fish, fruit flies, plants, molds, and even single-celled cyanobacteria.

Genetically engineered pig hearts survived more than a year in baboon abdomens

Genetically engineered pig hearts survived more than a year in baboon abdomens | Science, Technology, and Current Futurism | Scoop.it

The heart didn't beat for the baboon, but it did overcome the risk of organ rejection.

 

By breeding piglets with a few choice human genes, scientists were able to create sort-of-pig hearts that seem to be compatible with primate hosts. The organ wasn't used as a heart, but was instead grafted into the abdomen of an otherwise healthy baboon. After over a year, the best of the hearts are still living, viable organs. Next stop, the chest cavity!

 

Researchers at the National Heart, Lung and Blood Institute (NHLBI) of the National Institutes of Health will publish their results in the September issue of The Journal of Thoracic and Cardiovascular Surgery, though their findings were discussed several months ago at a conference. According to the study, the researchers experimented with different degrees of genetic modification in the pigs. They prevented all of the piglets from producing certain enzymes known to cause organ rejection in baboons (and, by extension, humans) but were given different gene alterations to keep blood from clotting, which is another common issue.

 

The most successful group had the human thrombomodulin gene added to their genomes. The expression of this gene prevented clotting, lead investigator Muhammad M. Mohiuddin said in a statement. While the average survival of the other groups were 70 days, 21 days and 80 days, the thrombomodulin group survived an average of 200 days in the baboon abdomen. And three of the five grafts in the group were still alive at 200 to 500 days since their grafting, when the study was submitted for review.

Computational Linguistics of Twitter Reveals the Existence of Global Superdialects | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it

The first study of dialects on Twitter reveals global patterns that have never been observed before. A dialect is a particular form of language limited to a specific region or social group. Linguists are fascinated by dialects because they reveal social classes, patterns of immigration and how groups have influenced each other in the past. Bruno Gonçalves at the University of Toulon in France and David Sánchez at the Institute for Cross-Disciplinary Physics and Complex Systems on the island of Majorca, Spain, say they have found a new way to study dialects on a global scale using messages posted on Twitter. The results reveal a major surprise about the way dialects are distributed around the world and provide a fascinating snapshot of how they are evolving under various new pressures, such as global communication mechanisms like Twitter.
