Scientists recognize intruders in noise
Posted by Scott Bleackley in categories: biological, economics, mathematics, security
## MATHEMATICS • MAY 24, 2021
# *Noise is commonly discarded, but identifying patterns in noise can be very useful.*
*Generalize the Hearst exponent by adding more coefficients in order to get a more complete description of the changing data. This makes it possible to find patterns in the data that are usually considered noise and were previously impossible to analyze.*

Could digital currencies put banks out of business? | The Economist
Posted by Derick Lee in categories: bitcoin, business, cryptocurrencies, economics, finance
Cryptocurrencies like Bitcoin have been billed as a major disruptor to finance. But digital currencies issued by governments might be even more radical—they may even threaten the future of traditional banking.

China’s tech hub Shenzhen to invest US$108 billion in R&D over 5 years
Posted by Derick Lee in categories: economics, quantum physics, robotics/AI
Local media reports quoted Wang as saying that artificial intelligence, 6G, quantum technology, driverless vehicles, intelligent networks and other “frontier areas” would be the focus of Shenzhen’s investment plans, while the value of its digital economy would account for more than 31 per cent of GDP by 2025.
Money will be used to support innovation in core technologies, city’s Communist Party chief Wang Weizhong says.

First nanoscale look at a reaction that limits the efficiency of generating clean hydrogen fuel
Posted by Saúl Morales Rodriguéz in categories: economics, energy, nanotechnology
Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen.
But a key step in that process, known as the oxygen evolution reaction or OER, has proven to be a bottleneck. Today it’s only about 75% efficient, and the precious metal catalysts used to accelerate the reaction, like platinum and iridium, are rare and expensive.
Now an international team led by scientists at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory has developed a suite of advanced tools to break through this bottleneck and improve other energy-related processes, such as finding ways to make lithium-ion batteries charge faster. The research team described their work in Nature today.

A neglected protein-rich ‘superfood’
Posted by Derick Lee in categories: economics, food, sustainability
And as well as producing less waste, insects can also live off food and biomass that would otherwise be thrown away, says Collins, contributing to the circular economy, where resources are recycled and reused. Insects can be fed agricultural waste, such as the stems and stalks from plants that people don’t eat, or scraps of food waste. To complete the recycling chain, their excrement can be used as fertiliser for crops.
Insects are a nutrition-dense source of protein embraced by much of the world. Why are some of us so squeamish about eating them?

Coal is losing the price war to wind and solar faster than anticipated
Posted by Jason Blain in categories: economics, energy
Coal is a highly polluting and expensive way to generate electricity. This analysis shows that we have economic alternatives to continuing to burn coal for power in the US. Furthermore, analyses such as “The 2035 Report” show that we can fully retire coal, stop building other fossil fuel plants (namely gas), and still reliably meet electricity demand, while providing a host of environmental and societal benefits. There are existing policies that can help policymakers closely examine the cost burden of generation resources used today, procure cheaper and cleaner generation resources going forward, and address current assets on the books. The continuation and intensification of the coal cost crossover demands attention from policymakers and consumers alike.
The costs of most existing US coal-fired power plants are now more expensive than the total costs of wind and solar.
