The first data from a repository of living human brain cells

Posted by in categories: biotech/medical, neuroscience, sustainability

PROFITABLY recycling waste is always a good idea. And the Allen Institute for Brain Science, in Seattle, has found a way to recycle what is perhaps the most valuable waste of all—living human brain tissue. Understandably, few people are willing to donate parts of their brains to science while they are still alive. But, by collaborating with seven local neurosurgeons, the institute’s chief scientist, Christof Koch, and his colleagues, have managed to round up specimens of healthy tissue removed by those surgeons in order to get to unhealthy parts beyond them, which needed surgical ministration. Normally, such tissue would be disposed of as waste. Instead, Dr Koch is making good use of it.

The repository the cells from these samples end up in is a part of a wider project, the Allen Cell Types Database. The first data from the newly collected human brain cells were released on October 25th. The Allen database, which is open for anyone to search, thus now includes information on the shape, electrical activity and gene activity of individual human neurons. The electrical data are from 300 live neurons of various types, taken from 36 people. The shapes (see picture for example) are from 100 of these neurons. The gene-expression data come from 16,000 neurons, though those cells are post-mortem samples.

The human brain is the most complex object in the known universe. Because it is more complicated than animal brains in ways that (say) human livers are not more complicated than animal livers, using animal brains as analogues of human ones is never going to be satisfactory. Dr Koch’s new database may therefore help explain what is special about human brains. That will assist understanding of brain diseases and disorders. It may also shed light on one of his particular interests, the nature of consciousness.

Could drone that can deliver cargo to islets in South China Sea secure presence in disputed waters?

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

China has carried out a test flight of an unmanned aerial vehicle, or drone, that could provide rapid cargo delivery to remote islets in the South China Sea without airstrips, in Beijing’s latest move to secure its presence in the disputed waters.

The drone – built from a modified low-cost fixed-wing plane – can carry 1.5 tonnes of cargo and land on a runway of just 200 metres, according to the Institute of Engineering Thermophysics at the Chinese Academy of Sciences in Beijing, which led the project.

It can also use a dirt track or grass field for take off and landing at military facilities that do not have an airfield, the institute said on its website on Friday.

It is now practical to refuel electric vehicles through thin air

Posted by in categories: sustainability, transportation

A WISE driver keeps an eye on the fuel gauge, to make timely stops at filling stations. For drivers of electric cars, though, those stations are few and far between. The infrastructure needed for refilling batteries has yet to be developed, and the technology which that infrastructure will use is still up for grabs. Most electric cars are fitted with plugs. But plugs and their associated cables and charging points bring problems. The cables are trip hazards. The charging points add to street clutter. And the copper wire involved is an invitation to thieves. Many engineers would therefore like to develop a second way of charging electric vehicles—one that is wireless and can thus be buried underground.

Electrical induction, the underlying principle behind wireless charging, was discovered by Michael Faraday in 1831, and is widely used in things such as electric motors and generators. Faraday observed that moving a conductor through a magnetic field induced a current in that conductor. Subsequent investigations showed that this also works if the conductor is stationary and the magnetic field is moving. Since electric currents generate magnetic fields, and if the current alternates so does the field, an alternating current creates a field that is continuously moving. This means that running such a current through a conductor will induce a similar current in another, nearby, conductor. That induced current can then be used for whatever purpose an engineer chooses.

Sony’s Pet Project, a New Robot Dog, to Be Unleashed Soon

Posted by in category: robotics/AI

Sony Corp. is planning next spring to roll out a dog-shaped pet robot similar to its discontinued Aibo with updated components that could allow it to control home appliances, people familiar with the matter said.

Sony is preparing for a media event in November to show off the product, the people said. It is unclear whether the new product will use the Aibo name and how much it will cost.

Ford’s Argo Buys Laser System Firm as It Boosts Driverless Car Development

Posted by in categories: robotics/AI, transportation

Argo AI LLC, a driverless-car developer controlled by Ford Motor Co., has purchased a 17-year-old company that makes laser systems needed to operate cars without human intervention, an important step for a conventional Detroit auto maker looking to boost its role in shaping the industry’s transformation.

Argo AI said Friday it is buying New Jersey-based Princeton Lightwave Inc. for an undisclosed price, a move that provides Ford with more immediate access to so-called lidar systems that use lasers to create a 3D view of the…
