Watch the moment India’s space program made a massive breakthrough.

Individuals who mine Bitcoins needn’t be miners. We call them ‘miners’ because they are awarded BTC as they solve mathematical computations. The competition to unearth these reserve coins also serves a vital purpose. They validate the transactions of Bitcoin users all over the world: buyers, loans & debt settlement, exchange transactions, inter-bank transfers, etc. They are not really miners. They are more accurately engaged in transaction validation or ‘bookkeeping’.

There are numerous proposals for how to incentivize miners once all 21 million coins have been mined/awarded in May 2140. Depending upon the network load and the value of each coin, we may need to agree on an alternate incentive earlier than 2140. At the opening of the 2015 MIT Bitcoin Expo, Andreas Antonopolous proposed some validator incentive alternatives. One very novel suggestion was based on game theory and involved competition and status rather than cash payments.

I envision an alternative approach—one that also addresses the problem of miners and users having different goals. In an ideal world the locus of users should intersect more fully with the overseers…

To achieve this, I have proposed that every wallet be capable of also mining, even if the wallet is simply a smartphone app or part of a cloud account at an exchange service. To get uses participating in validating the transactions of peers, any transaction fee could be waived for anyone who completes 1 validation for each n transactions. (Say one validation for every five or ten transactions). In this manner, everyone pitches in a small amount of resources to maintain a robust network.

A bit of every speculative propulsion system.

When Greg Matloff’s “Solar Sail Starships: Clipper Ships of the Galaxy” appeared in JBIS in 1981, the science fictional treatments of interstellar sails I had been reading suddenly took on scientific plausibility. Later, I would read Robert Forward’s work, and realize that an interstellar community was growing in space agencies, universities and the pages of journals. Since those days, Matloff’s contributions to the field have kept coming at a prodigious rate, with valuable papers and books exploring not only how we might reach the stars but what we can do in our own Solar System to ensure a bright future for humanity. In today’s essay, Greg looks at interstellar propulsion candidates and ponders the context provided by Breakthrough Starshot, which envisions small sailcraft moving at 20 percent of the speed of light, bound for Proxima Centauri. What can we learn from the effort, and what alternatives should we consider as we ponder the conundrum of interstellar propulsion?

• Mark Zuckerberg spoke at Harvard’s commencement, saying that basic income is an “idea worth exploring.”
• With his endorsement of UBI, Zuckerberg joins a growing list of experts and innovators who believe supporting basic human needs must precede innovation.

This week Mark Zuckerberg spoke to the latest class of Harvard graduates, offering advice about the future and inspiration to grow on. Among his ideas was the notion that universal basic income (UBI), a standard base “salary” for each member of society that can help meet our basic needs regardless of the work we do, is worth exploring.

A major new breakthrough in jet propulsion technology could revolutionize the aerospace industry, paving the way for plasma jet engines that could carry a craft to the edge of space using only air and electricity.

Berkant Göksel, the lead researcher in a new study by the Technical University of Berlin, says his team have successfully completed tests on plasma engines that could take future aircrafts to altitudes of 30 miles (50km) and beyond.

People in a minimally conscious state have been “woken” for a whole week after a brief period of brain stimulation. The breakthrough suggests we may be on the verge of creating a device that can be used at home to help people with disorders of consciousness communicate with friends and family.

People with severe brain trauma can fall into a coma. If they begin to show signs of arousal but not awareness, they are said to be in a vegetative state. If they then show fluctuating signs of awareness but cannot communicate, they are described as being minimally consciousness.

A breakthrough solution to oil spills!

• Of the estimated 100,000 mushroom species on Earth, only about 80 glow. Scientists uncovered the explanation behind two of these glowing mushrooms.
• Studying the mushrooms allowed researchers to make chemicals that glow various colors that may help us make more scientific breakthroughs.

Mushrooms are our favorite fungi. From savory dishes to surprising video game power-ups — we can’t seem to get enough of the little things. What’s more interesting, however, is the fact that mushrooms can be far more relevant to our own progress as a society than we imagined. The Neonothopanus gardneri and Neonothopanus nambi are two distinct species of glow-in-the-dark mushroom found in Brazil and Vietnam respectively, that have reshaped our perspective on bioluminescence permanently.
