Today, economist and Nobel laureate, Paul Krugman, wrote in the New York Times, that Bitcoin is taking us back 300 years in monetary evolution. As a result, he predicts all sorts of bad things.

A significant basis for Mr. Krugman’s argument is that the US dollar has value because men with guns say it does.

Is Bitcoin erasing 300 years of monetary evolution?

Running with the metaphor that fundamental change to an economic mechanism represents ‘evolution’, I think a more accurate statement is that Bitcoin is not erasing the lessons of history. Rather, it is the current step in the evolution of money. Of course, with living species, evolution is a gradual process based on natural selection and adaptation. With Bitcoin, change is coming up in the rear view mirror at lightning speed.

18-year-old Ewin Tang has proven that classical computers can solve the “recommendation problem” nearly as fast as quantum computers. The result eliminates one of the best examples of quantum speedup.

Lithium-ion batteries are effective, but they can be a bit on the expensive side. Striking a balance between common materials and efficiency is important, and regular old salt looks like it could fit the bill – after a few kinks are ironed out. Now, researchers at King Abdullah University of Science and Technology (KAUST) have developed a way to make “disordered” graphene that can help improve the sodium-ion battery recipe.

Experts widely agree that human activities are harming the global environment. Since the Industrial Revolution, the world economy has grown dramatically. Overall this is a success story, since rising incomes have lifted millions of people out of poverty. But it has been fueled by population growth and increasing consumption of natural resources.

Rising demand to meet the needs of more than 7 billion people has transformed land use and generated unprecedented levels of pollution, affecting biodiversity, forests, wetlands, water bodies, soils and air quality.

A discussion about why life extension isn’t selfish.

The topic of life extension is much more debated these days than before. As a result, more people who are not in the field talk about it, and they don’t always do so in praising terms. Articles written by outsiders tend to be conservative at best and fear-mongering at worst, mainly focusing on the potential downsides of life-extending technologies without paying much attention, if any, to the benefits, as if there weren’t any to begin with.

One accusation that is often thrown at life extensionists is that they would be selfish for wanting to extend their lives. It is all too easy to say that all that life extensionists think about is their own benefit while disregarding the common good, but it’s not too difficult to see how this is entirely wrong.

Despite its remaining mystery, the ocean is a complex working environment, widely used for fishing, shipping and recreation; but so far largely untapped for energy generation. OCEANERA-NET seeks to give the industry the boost it needs.

The European Union coastline runs to around 66 000 kilometres. This vast stretch holds a largely unexploited potential for ocean generated electricity, calculated to be around 380 GW by DG MARE (the EU Directorate responsible), constituting a significant contribution to the EU’s 2020 targets for renewable energy.

Presently, there are a number of Member States funding research and development into ocean energy technology. However, these efforts are not coordinated and so not the game-changers they could be.

The energy-generating potential of solar panels – and a key limitation on their use – is a result of what they’re made of. Panels made of silicon are declining in price such that in some locations they can provide electricity that costs about the same as power from fossil fuels like coal and natural gas. But silicon solar panels are also bulky, rigid and brittle, so they can’t be used just anywhere.

In many parts of the world that don’t have regular electricity, solar panels could provide reading light after dark and energy to pump drinking water, help power small household or village-based businesses or even serve emergency shelters and refugee encampments. But the mechanical fragility, heaviness and transportation difficulties of silicon solar panels suggest that silicon may not be ideal.

Building on others’ work, my research group is working to develop flexible solar panels, which would be as efficient as a silicon panel, but would be thin, lightweight and bendable. This sort of device, which we call a “solar tarp,” could be spread out to the size of a room and generate electricity from the sun, and it could be balled up to be the size of a grapefruit and stuffed in a backpack as many as 1,000 times without breaking. While there has been some effort to make organic solar cells more flexible simply by making them ultra-thin, real durability requires a molecular structure that makes the solar panels stretchable and tough.

The weirder Goop went, the more its readers rejoiced. And then, of course, the more Goop was criticized: by mainstream doctors with accusations of pseudoscience, by websites like Slate and Jezebel saying it was no longer ludicrous — no, now it was dangerous. And elsewhere people would wonder how Gwyneth Paltrow could try to solve our problems when her life seemed almost comically problem-free. But every time there was a negative story about her or her company, all that did was bring more people to the site — among them those who had similar kinds of questions and couldn’t find help in mainstream medicine.

We’re at the point where AI can take on mundane household tasks – if slowly. And the implications of this technology go far beyond folding laundry.
