New Renewable Energy Ideas

Forcing countries to agree to emissions caps will never work, argue Ted Nordhaus and Michael Shellenberger. Instead, they say, the focus should be on technology innovations.

Nations should focus on lowering the cost of clean energy, not raising the cost of fossil energy. The goal? Make clean energy cheap enough to become a viable option for poor as well as rich nations. Until that happens, emissions will continue to rise, and no effort to regulate carbon can succeed. How do we accomplish that? Stop subsidizing old technology that will never compete with fossil fuels and create incentives for innovation. Along with ramping up support for research, governments should buy cutting-edge clean-energy technologies, prove them—and then give away the intellectual property, so others can improve on it.

This 5-minute neck scan can spot dementia 10 years before it emerges

The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.

  • The study measured the stiffness of blood vessels in middle-aged patients over time.
  • Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
  • The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.

Preserving truth: How to confront and correct fake news

Journalism got a big wake up call in 2016. Can we be optimistic about the future of media?

  • "[T]o have a democracy that thrives and actually that manages to stay alive at all, you need regular citizens being able to get good, solid information," says Craig Newmark.
  • The only constructive way to deal with fake news? Support trustworthy media. In 2018, Newmark was announced as a major donor of two new media organizations, The City, which will report on New York City-area stories which may have otherwise gone unreported, and The Markup, which will report on technology.
  • Greater transparency of fact-checking within media organizations could help confront and correct fake news. Organizations already exist to make media more trustworthy — are we using them? There's The Trust Project, International Fact-Checkers Network, and Tech & Check.
