University of Rochester scientists show how asteroids could be future viable space habitats using physics and engineering principles. During this past year, Jeff Bezos launched himself into space, while Elon Musk funded a space flight for a non-astronaut crew. Space collaborations between governmen
, are becoming more common. However, with the recent emergence of the so-called “New Space” movement, aerospace companies are working to develop low-cost access to space for everyone, not only billionaires.
“All those flying mountains whirling around the sun might provide a faster, cheaper, and more effective path to space cities.” —and books such as Orson Scott Card’s 1985 novelhave depicted O’Neill cylinder-like habitats populated with human beings. Both Bezos and Musk have referenced O’Neill cylinders in their visions for future space habitats.
“All those flying mountains whirling around the sun might provide a faster, cheaper, and more effective path to space cities,” Frank says. Miklavčič and his colleagues conducted calculations of forces, materials, and strategies for constructing rotating asteroid settlements and came up with an idea for containing the rubble that would inevitably result from forming an O’Neill cylinder out of an asteroid.The researchers imagine covering an asteroid in a flexible, mesh bag made of ultralight and high-strength carbon nanofibers—tubes made of carbon, each just a few atoms in diameter.

Research: When Mindfulness Does — and Doesn’t — Help at WorkMindfulness meditation practices can be an effective way to reduce stress and improve well-being in certain contexts. But as more and more employers offer some form of mindfulness training to their employees, it isn’t always clear whether these programs are actually paying off. To explore the impact of mindfulness in the workplace, the authors conducted a series of field studies in real-world work environments — and they found that while mindfulness can in fact be beneficial in some situations, it can be less effective (or even counterproductive) in others. Specifically, they found that both breath-based and loving-kindness meditation can help reduce the stress associated with emotionally charged social interactions, but that breath-focused meditation can actually make people less helpful in situations that require them to take accountability. As such, especially for programs targeting managers or executives (whose roles often necessitate the ability to take responsibility for past mistakes and proactively address issues), the authors suggest that breath-based meditation may not be the best approach. They go on to offer three strategies to help organizations implement the targeted mindfulness programs that will be most beneficial for everyone, ultimately suggesting that it’s critical for us all to identify the mindfulness practices that will be most effective for our unique roles, routines, and minds.
