An early model Nissan Leaf has been given a new lease of life with a battery upgrade for a fraction of the price it would cost if done by Nissan.

The 2011 Nissan Leaf came with a 24kWh battery, and even when new had a very modest driving range of 117km based on the US EPA ratings.

But after nine years of use, this particular Nissan Leaf’s maximum range had degraded to around 100km, prompting owner Daniel Öster to undertake an upgrade using a 30kWh battery from a 2017 Nissan Leaf.

In the distant past, there was a proverbial “digital divide” that bifurcated workers into those who knew how to use computers and those who didn’t.[1] Young Gen Xers and their later millennial companions grew up with Power Macs and Wintel boxes, and that experience made them native users on how to make these technologies do productive work. Older generations were going to be wiped out by younger workers who were more adaptable to the needs of the modern digital economy, upending our routine notion that professional experience equals value.

Of course, that was just a narrative. Facility with using computers was determined by the ability to turn it on and log in, a bar so low that it can be shocking to the modern reader to think that a “divide” existed at all. Software engineering, computer science and statistics remained quite unpopular compared to other academic programs, even in universities, let alone in primary through secondary schools. Most Gen Xers and millennials never learned to code, or frankly, even to make a pivot table or calculate basic statistical averages.

There’s a sociological change underway though, and it’s going to make the first divide look quaint in hindsight.

Chinese electric startup Kandi announces that its small K27 electric car has been approved for California roads and it is going to cost only $7,999 in the state after incentives.

Several Chinese automakers are currently looking to expand outside of China, and that’s especially true of electric vehicle makers.

Even foreign automakers, like Volvo and BMW, are now producing electric vehicles in China and exporting them globally. The Chinese-made Polestar 2 is due later this year. BMW is also looking at bringing Chinese made EVs to the US.

Researchers at the University of Rochester and Cornell University have taken an important step toward developing a communications network that exchanges information across long distances by using photons, mass-less measures of light that are key elements of quantum computing and quantum communications systems.

The research team has designed a nanoscale node made out of magnetic and semiconducting materials that could interact with other nodes, using laser light to emit and accept photons.

The development of such a quantum network—designed to take advantage of the physical properties of light and matter characterized by quantum mechanics—promises faster, more efficient ways to communicate, compute, and detect objects and materials as compared to networks currently used for computing and communications.

Artificial intelligence helps scientists make discoveries, but not everyone can understand how it reaches its conclusions. One UMaine computer scientist is developing deep neural networks that explain their findings in ways users can comprehend, applying his work to biology, medicine and other fields.

Interpretable machine learning, or AI that creates explanations for the findings it reaches, defines the focus of Chaofan Chen’s research. The assistant professor of computer science says interpretable machine learning also allows AI to make comparisons among images and predictions from data, and at the same time, elaborate on its reasoning.

Scientists can use interpretable machine learning for a variety of applications, from identifying birds in images for wildlife surveys to analyzing mammograms.
