It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries.

Cities produce and must manage huge quantities of wastewater. Researchers at the University of Illinois at Urbana-Champaign have developed a model to clarify what parts of the world may benefit most from re-circulation of human-waste-derived nitrogen, potassium and phosphorus from cities and back into farm fields. They report their findings in the journal Nature Sustainability.

“We grow our crops in the field, apply nutrient-rich fertilizers, eat the crops, excrete all of the nitrogen, phosphorus and potassium and then those nutrients end up at the wastewater treatment plant,” said Jeremy Guest, a civil and environmental engineering professor and study co-author. “It is a very linear, one-directional flow of resources. Engineering a more circular nutrient cycle would create opportunities that could benefit the environment, economy and agriculture.”

Imagine something similar to the Great Depression of 1929 hitting the world, but this time it never ends.

Economic modelling suggests this is the reality facing us if we continue emitting greenhouse gases and allowing temperatures to rise unabated.

Economists have largely underestimated the global economic damages from climate change, partly as a result of averaging these effects across countries and regions, but also because the likely behaviour of producers and consumers in a climate change future isn’t usually taken into consideration in climate modelling.

Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO₂ from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO₂. This work is presented at the Goldschmidt conference in Boston.

Scientists are already working to slow global warming by removing carbon dioxide from the atmosphere, but there are serious practical and economic limits on developing the technology. Now, for the first time, researchers have explained how magnesite forms at low temperature, and offered a route to dramatically accelerating its crystallization. A tonne of naturally-occurring magnesite can remove around half a tonne of CO₂ from the atmosphere, but the rate of formation is very slow.

Project leader, Professor Ian Power (Trent University, Ontario, Canada) said:

A research analyst at Swiss investment bank UBS believes the cost of energy renewables could be so near to zero by 2030 “it will effectively be free,” according to a projections published on Monday. If renewables could soon be cheaper than all the alternative energy sources, and that this “is great news for the planet, and probably also for the economy.”

The analysis, published in the Financial Times, explains that solar and wind farms are getting bigger, and that the potential of this sort of cheap, green energy is far-reaching and will only get cheaper. “In 2010, using solar power to boil your kettle would have cost you about £0.03,” the analyst writes in FT. “By 2020, according to estimates by our research team at UBS, the cost will have fallen to half a penny.” And just ten years later, the costs will be so minuscule, it will practically be free.

Just as Henry Ford’s assembly line revolutionized the automobile industry, synthetic biology is being revolutionized by automated DNA assembly (see SynBioBetaLive! with Opentrons). The key features of an assembly line translate well into the field of synthetic biology – speed, accuracy, reproducibility and validation. Instead of welding chassis together, small robotic arms are lifting delicate plates holding dozens of samples, adding and removing miniscule amounts of fluid.

We explore some of the ramifications arising from superflares on the evolutionary history of Earth, other planets in the solar system, and exoplanets. We propose that the most powerful superflares can serve as plausible drivers of extinction events, and that their periodicity corresponds to certain patterns in the terrestrial fossil diversity record. On the other hand, weaker superflares may play a positive role in enabling the origin of life through the formation of key organic compounds. Superflares could also prove to be quite detrimental to the evolution of complex life on present-day Mars and exoplanets in the habitable zone of M- and K-dwarfs. We conclude that the risk posed by superflares has not been sufficiently appreciated, and that humanity might potentially witness a superflare event in the next $\sim {10}^{3}$ years, leading to devastating economic and technological losses. In light of the many uncertainties and assumptions associated with our analysis, we recommend that these results should be viewed with due caution.

By allowing them to launch higher-power small satellites on smaller rockets, as opposed to the larger, and more expensive rockets that current technology requires.

Made in Space is developing power systems for small satellites that can provide up to 5 kW of solar power and is enabled by the company’s Archinaut on-orbit manufacturing and assembly technology. Current small satellites are typically constrained to 1 kW of power or less.

Let us frame the question, by reviewing what miners really do…

Miners play a critical role in the Bitcoin network. Their activity (searching for a nonce) results in assembling an immutable string of blocks that corroborate and log the universal transaction record. They are the distributed bookkeepers that replace old-school banks in recording and vouching for everyone’s purchase or savings.

From the perspective of a miner, there is no obvious connection between their activity and the worldwide network of bitcoin transactions and record keeping. They are simply playing an online game and competing against thousands of other miners in an effort to solve a complex and ongoing math problem. As they arrive at answers to small pieces of the problem, they are rewarded with bitcoin, which can be easily translated into any currency.

What is the Problem?

A BASIC income (BI) is defined as a modest, regular payment to every legal resident in the community, paid unconditionally as a right, regardless of income, employment or relationship status.

Contrary to conventional wisdom, the case for BI does not rest on the assumption that robots and artificial intelligence will cause mass unemployment or that it would be a more efficient way of relieving poverty than present welfare systems (although it would). The main arguments are ethical and relate to social justice, individual freedom and the need for basic security.
