Teaching computers to recognize objects better

September 23, 2013

mit_hogles

Object-recognition software (which tries to identify objects in digital images) is still fairly limited.

So, in an attempt to improve it, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory have created a system that, in effect, allows humans to see the world the way an object-recognition system does.

The system takes an ordinary image, translates it into the mathematical representation used… read more

Scientists claim discovery of life coming to Earth from space [UPDATED]

September 20, 2013

Scientists from the University of Sheffield believe they have found life arriving to Earth from space after sending a balloon 27km into the stratosphere.

After it landed, they discovered that they had captured a diatom fragment and some unusual biological entities from the stratosphere, all of which are too large to have come from Earth, the scientists suggest.

The team was led by Professor… read more

A gene for forgetting

Could lead to new PTSD treatments
September 20, 2013

A new study from MIT reveals a gene that is critical to the process of memory extinction (when older memories are replaced with new experiences).

Enhancing the activity of this gene, known as Tet1, might benefit people with posttraumatic stress disorder (PTSD) by making it easier to replace fearful memories with more positive associations, says Li-Huei Tsai, director of MIT’s… read more

Achieving fault-tolerant quantum computing

Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today’s most powerful supercomputers, or things not even feasible with today’s computers.

But first, we need “fault-tolerant” quantum computers. A small but important step toward this goal has been achieved by an international collaboration of researchers from China’s Tsinghua University and the U.S. Department of Energy… read more

Tesla plans ‘mostly autonomous’ car within three years

Elon Musk has decided that the next step for Tesla Motors cars is to go (mostly) autonomous, IEEE Spectrum reports.

From the Financial Times:
“We should be able to do 90 percent of miles driven within three years,” [Musk] said. Mr Musk would not reveal further details of Tesla’s autonomy project, but said it was “internal development” rather than technology being supplied by another company.read more

The world’s first low-cost atomic force microscope (AFM) has been developed in Beijing by a group of PhD students from University College London (UCL), Tsinghua University, and Peking University — using LEGO.

LEGO2NANO brought together students, experienced makers and scientists to take on the challenge of building a cheap and effective AFM, a device able to probe objects only a nanometer in size… read more

‘Wired microbes’ generate electricity from sewage

September 19, 2013

Interdisciplinary team creates ‘microbial battery’ driven by naturally occurring bacteria that evolved to produce electricity as they digest organic material.

Engineers at Stanford University have devised a new way to generate electricity from sewage using naturally occurring “wired microbes” as mini power plants that produce electricity as they digest plant and animal waste.

Nearly half of US jobs could be at risk of computerization, Oxford Martin School study shows

Transport, logistics, and office roles most likely to come under threat

probability of computerisation featired

Nearly half of U.S. jobs could be susceptible to computerization over the next two decades, a study from the Oxford Martin Programme on the Impacts of Future Technology suggests.

The study, a collaboration between Dr. Carl Benedikt Frey (Oxford Martin School) and Dr. Michael A. Osborne (Department of Engineering Science, University of Oxford), found that jobs in transportation, logistics, and office/administrative support are at “high… read more

An experimental spaceplane with ‘aircraft-like’ operations in orbit

September 19, 2013

The current generation of satellite launch vehicles is expensive to operate, often costing hundreds of millions of dollars per flight. Moreover, U.S. launch vehicles fly only a few times each year and normally require scheduling years in advance, making it extremely difficult to deploy satellites without lengthy pre-planning. Quick, affordable and routine access to space is increasingly critical for U.S. Defense Department operations.

Imagine a fully reusable unmanned vehicle… read more

A smartphone ‘microscope’ that can detect a single virus, nanoparticles

September 19, 2013

smartphone microscope

UCLA engineers have created a 1/2-pound, portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment.

“This cellphone-based imaging platform could be used for specific and sensitive detection of sub-wavelength [smaller than the wavelength of light] objects.

These include bacteria and viruses and therefore could enable the practice… read more

Where is imagination located in the human brain?

September 18, 2013

Schlegel-mental-workspace-image-high-res.jpg

Imagination lies in a widespread neural network — the brain’s “mental workspace” — that consciously manipulates images, symbols, ideas and theories and gives humans the laser-like mental focus needed to solve complex problems and come up with new ideas, Dartmouth researchers conclude in a new study.

“Our findings move us closer to understanding how the organization of our brains sets us apart from other species and provides… read more

BRAIN initiative report lists detailed research priorities

A scientific team has released a report that identifies research priorities for the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) initiative, Science Insider reports.

The report lists nine top research priorities. It highlights the need for cheaper, faster technologies that can trace connections between individual brain cells and record large networks of cells acting in synchrony.

It calls for development of tools that can… read more

Northwestern University researchers have found biological evidence linking the ability to keep a beat to the neural encoding of speech sounds.

The study has significant implications for reading, according to Nina Kraus, director of Northwestern’s Auditory Neuroscience Laboratory.

The study demonstrates that accurate beat-keeping involves synchronization between the parts of the brain responsible for hearing as well as movement.
