Incentivize negative emissions responsibly

Focus on negative emissions

Using Language More Responsibly

C reating a common language provides one of a social enter-prise's defining moments, be it a technical, scientific, or humanistic venture. The lan-guage's most obvious utility derives from its allowing a field's participants to communicate among themselves. Its importance extends beyond this function , however. More than a neutral medium through which we exchange information , language serves t...

The promise of negative emissions.

IN THEIR PERSPECTIVE “The trouble with negative emissions” (14 October, p. 182), K. Anderson and G. Peters assert that negative-emissions technologies are an “unjust and high-stakes gamble.” This characterization would sideline negativeemissions technologies and remove potentially important options from the portfolio for mitigating and ameliorating climate change. As Anderson and Peters acknowl...

Incentivize P2P Systems with Lightweight Micropayments

We introduce incentives to P2P systems via micropayments. We first propose a low-latency micropayment system built upon high-latency distributed macropayment systems. We show that our system is non-repudiable, fast, and discentralized. We then build the micropayment system that enable Tor clients to pay relays for bandwidth with little computational overhead.

The dilemma of raising awareness “responsibly”

S cience is often the best and sometimes the only means to address health, environmental, economic and other challenges. Debate with the public about research, its results and possible applications ensures a rational, informed process to find sustainable solutions. However, there is a conundrum at the heart of science communication, outreach activities, public or upstream engagement and Respons...
