UMN research shows people can control robotic arm with their minds

Posted by in categories: biotech/medical, robotics/AI

Researchers at the University of Minnesota have made a major breakthrough that allows people to control a robotic arm using only their minds. The research has the potential to help millions of people who are paralyzed or have neurodegenerative diseases.

The study is published online today in Scientific Reports, a Nature research journal.

Single Cell Analysis Technologies Help Generate Unprecedented Maps of Disease

Posted by in categories: biotech/medical, evolution

Astronomy was born when early scientists peered into the sky with their naked eyes and recorded what they could see above them. Then, the invention of the telescope brought forth new insights. And today, astronomers conduct their studies from big observatories and launch sophisticated telescopes into space for a much more in-depth look.

Now, a similar evolution is occurring in biology as scientists develop new techniques for taking a closer look at cells—the basic living units of organs. The origins of cell biology date back to 1,665 when Robert Hooke was the first to look at a cell under a simple compound microscope. But while the development of more powerful microscopes such as the scanning electron microscope has allowed scientists to take a peek at molecules smaller than a billionth of a meter, until recently they have never had the ability to look at the molecular profile of a single cell.

Yale researchers across disciplines are using single cell technologies to profile various kinds of cells that exist together in both healthy and diseased organs and create the most detailed blueprints of diseases to date, as well as to better understand how various cells develop over time and interact with one another. Through creating these “cell atlases” of organs throughout the body, they hope to shed light on the mechanisms of a wide variety of diseases and biological development.

The evolution and development of consciousness: the subject-object emergence hypothesis

Posted by in categories: evolution, neuroscience

A strategy for investigating consciousness that has proven very productive has focused on comparing brain processes that are accompanied by consciousness with processes that are not. But comparatively little attention has been given to a related strategy that promises to be even more fertile. This strategy exploits the fact that as individuals develop, new classes of brain processes can transition from operating ‘in the dark’ to becoming conscious. It has been suggested that these transitions occur when a new class of brain processes becomes object to a new, emergent, higher-level subject. Similar transitions are likely to have occurred during evolution. An evolutionary/developmental research strategy sets out to identify the nature of the transitions in brain processes that shift them from operating in the dark to ‘lighting up’. The paper begins the application of this strategy by extrapolating the sequence of transitions back towards its origin. The goal is to reconstruct a minimally-complex, subject-object subsystem that would be capable of giving rise to consciousness and providing adaptive benefits. By focusing on reconstructing a subsystem that is simple and understandable, this approach avoids the homunculus fallacy. The reconstruction suggests that the emergence of such a minimally-complex subsystem was driven by its capacity to coordinate body-environment interactions in real time e.g. hand-eye coordination. Conscious processing emerged initially because of its central role in organising real-time sensorimotor coordination. The paper goes on to identify and examine a number of subsequent major transitions in consciousness, including the emergence of capacities for conscious mental modelling. Each transition is driven by its potential to solve adaptive challenges that cannot be overcome at lower levels. The paper argues that mental modelling arose out of a pre-existing capacity to use simulations of motor actions to anticipate the consequences of the actions. As the capacity developed, elements of the simulations could be changed, and the consequences of these changes could be ‘thought through’ consciously. This enabled alternative motor responses to be evaluated. The paper goes on to predict significant new major transitions in consciousness.

UK’s National Grid launches drone trial to fully automate asset inspections

Posted by in categories: drones, health, robotics/AI

UK’s National Grid Electricity Transmission (NGET) is launching trials to fully automate the corrosion inspection of electricity transmission pylons with the help of autonomous drones.

NGET owns 21,900 steel lattice pylons that carry overhead transmission conductor wires in England and Wales. Transmission pylon steelwork conditions can deteriorate through corrosion, so periodic assessments are made to understand the health of the network. NGET inspects around 3,650 steel lattice pylons each year, capturing high definition still color images of steelwork using helicopters and manually-operated drones.
