While the USA has been extremely concerned about losing jobs (particularly manufacturing jobs to China), China performed a survey of businesses in the American Chamber of Commerce in Beijing and found that 25% had moved or were planning to move their businesses out of China. Half were going to other Asian countries and 40% to America, Canada or Mexico.

China’s worker wages are rising about 7–8% each year and they have a shrinking working age population as the people age.

China is making big moves in automation and large scale deployment of robotics. In 2014, President Xi Jinping talked about a robotics revolution. China has been the number one buyer of industrial robots since 2013. However, China lags other nations in terms of robots per worker.

We will need a good dose of healthy stoicism if we are to survive in the world after work. Luxury items will be significantly reduced in the world we’re imagining. Stoics like Marcus Aurelius and Seneca recommended that we adjust our desires to simple, reliable pleasures, like fresh water, decent bread, modest clothing, and good friends. Luxury pleasures are rare and unreliable so we suffer more when they fail to materialize.

But chocolate cake is delicious and diamonds are beautiful. When Plato sketched a Spartan lifestyle in the Republic, his friends accused him of designing a city for pigs not humans — and they demanded that he add spices and luxury to the imagined utopia. While I’m sensitive to this worry, I hasten to point out that many Americans are currently, and by their own initiative, downsizing their sense of the good life. The contemporary “tiny house movement” — which builds elegant housing around 1/10th the size of average homes — is already the kind of stoic adjustment that Americans will need to make when we’re all unemployed.

We all love graphene — the one-atom-thick sheets of carbon aren’t just super flexible, harder than diamond, and stronger than steel, they’ve also recently become superconductors in their own right.

But it’s not the only over-achieving nanomaterial out there. Researchers have just simulated a stretched out, one-dimensional (1D) chain of boron, predicting that the material could have even weirder properties than graphene.

To be clear, 1D boron chains haven’t been created as yet — so far, this research is purely based on detailed computer simulations of the new material.

In what could be called a classic “Eureka” moment, UC Santa Barbara materials researchers have discovered a simple yet effective method for mastering the electrical properties of polymer semiconductors. The elegant technique allows for the efficient design and manufacture of organic circuitry (the type found in flexible displays and solar cells, for instance) of varying complexity while using the same semiconductor material throughout.

“It’s a different strategy by which you can take a material and change its properties,” said Guillermo Bazan, a professor of chemistry and at UCSB. With the addition of fullerene or copper tetrabenzoporphyrin (CuBP) molecules in strategic places, the charge carriers in semiconducting materials—negative electrons and positive “holes”—may be controlled and inverted for better device performance as well as economical manufacture. The discovery is published in a pair of papers that appear in the journals Advanced Functional Materials and Advanced Electronic Materials.

In the realm of , device functionality depends on the movement of the appropriate charge carriers across the material. There have been many advances in the synthesis of high-mobility, high-performance materials, said lead author Michael Ford, graduate student in materials, but the fine control of the electrons and holes is what will allow these sophisticated polymers to reach their full potential.

Nice.


Summary: Researchers report adult neurogenesis not only helps increase the number of cells in a neural network, it also promotes plasticity in the existing network. Additionally, they have identified the role the Bax gene plays in synaptic pruning.

One goal in neurobiology is to understand how the flow of electrical signals through brain circuits gives rise to perception, action, thought, learning and memories.

Linda Overstreet-Wadiche, Ph.D., and Jacques Wadiche, Ph.D., both associate professors in the University of Alabama at Birmingham Department of Neurobiology, have published their latest contribution in this effort, focused on a part of the brain that helps form memories — the dentate gyrus of the hippocampus.
