Last summer, at a time when the pandemic had strained many people’s finances, inflation was rising and unemployment was still high, the sight of the richest man in the world joyriding in space hit a nerve. On July 20 Amazon founder Jeff Bezos rode to the edge of space onboard a rocket built by his company Blue Origin. A few weeks earlier ProPublica had revealed that he did not pay any income taxes for two years, and in other years he paid a tax rate of just 0.98 percent. To many watching, it rang hollow when Bezos thanked Amazon’s workers, whose low-paid labor had enriched him enough to start his own rocket company, even though Amazon had quashed workers’ efforts to unionize several months before. The fact that another billionaire, Richard Branson, had also launched himself onboard his own company’s rocket just a week earlier did not help.

COVID changed many people’s willingness to shrug off the excesses of the rich. The pandemic drew an impossible-to-ignore distinction between those who can literally escape our world and the rest of us stuck on the ground confronting the ills of Earth: racism, climate change, global diseases. Even several members of Congress expressed their disapproval of Bezos. “Space travel isn’t a tax-free holiday for the wealthy,” said Representative Earl Blumenauer of Oregon. Bezos and Branson putting the spotlight on themselves as passengers served to downplay the work that hundreds of scientists and engineers at Blue Origin and Virgin Galactic had put into designing, building and testing their spacecraft. It also masked the reality that advances in private spaceflight really could eventually pay off in greater access to space for all and more opportunities for scientific research that could benefit everyone. All their flights did was give the impression that space—historically seen as a brave pursuit for the good of all humankind—has just become another playground for the 0.0000001 percent.

New governance models and new ways for us to interact are needed to help address existential challenges like climate change.

Scientists from the Max Planck Institute for Polymer Research, Paderborn University, and the University of Konstanz have succeeded in achieving a rare quantum state. They are the first to have demonstrated Wannier-Stark localization in a polycrystalline substance. Predicted around 80 years ago, the effect has only recently been proven — in a monocrystal. Until now, researchers assumed this localization to be possible only in such monocrystalline substances which are very complicated to produce. The new findings represent a breakthrough in the field of physics and could in future give rise to new optical modulators, for example, that can be used in information technologies based on light, among other things. The physicists have published their findings in the well-respected technical journal, Nature Communications.

Stronger and faster than lightning

The atoms of a crystal are arranged in a three-dimensional grid, held together by chemical bonds. These bonds can, however, be dissolved by very strong electric fields which displace atoms, even going so far as to introduce so much energy into the crystal that it is destroyed. This is what happens when lightning strikes and materials liquefy, vaporize or combust, for example. To demonstrate Wannier-Stark localization, the scientists’ experiments involved setting up electric fields of several million volts per centimeter, much stronger than the fields involved in lightning strikes. During this process, the electronic system of a solid — in this case, a polycrystal — is forced far from a state of equilibrium for a very short time. Wannier-Stark localization involves virtually shutting down some of the chemical bonds temporarily. This state can only be maintained for less than a picosecond — one millionth of one millionth of a second — without destroying the substance.

READER QUESTION: If humans don’t die out in a climate apocalypse or asteroid impact in the next 10,000 years, are we likely to evolve further into a more advanced species than what we are at the moment? Harry Bonas, 57, Nigeria

Humanity is the unlikely result of four billion years of evolution.

From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves—evolution shaped us.

As cities address climate change, they are looking at passive buildings and novel approaches to energy and heating.

Cities are being challenged to tackle climate change through net-zero strategies that include passive homes, geothermal heating, and more.

Using a unique hydrogel, scientists in Saudi Arabia created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity. The proof-of-concept design, described March 1 in the journal Cell Reports Physical Science, offers a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.

“A fraction of the world’s population still doesn’t have access to clean water or green power, and many of them live in rural areas with arid or semi-arid climate,” says senior author Peng Wang, a professor of environmental science and engineering at the King Abdullah University of Science and Technology (KAUST). “Our design makes water out of air using clean energy that would’ve been wasted and is suitable for decentralized, small-scale farms in remote places like deserts and oceanic islands.”

The system, called WEC²P, is composed of a solar photovoltaic panel placed atop a layer of hydrogel, which is mounted on top of a large metal box to condense and collect water. Wang and his team developed the hydrogel in their prior research, and the material can effectively absorb water vapor from ambient air and release the water content when heated.

As I have contemplated climate change over the past months, it seems as though linking currency to carbon could open the door to a more sustainable economy.

Abstract: The pandemic has launched a debate about the future of work around the world. Those who can work remotely have often found they prefer remote or flexible, hybrid options. The Great Resignation has put upward pressure on wages and benefits in the service sector, encouraging the implementation of automation. Climate change mitigation is encouraging a shift towards “green jobs.” Rapid changes in the labor market have made the payoffs of higher education uncertain for young people, while many societies are entering an old-age dependency crisis with too few workers paying taxes for growing numbers of pensioners. Before the pandemic proposals for universal basic income (UBI) were seen as necessary adaptations to imminent technological unemployment, and the during the pandemic many countries provided temporary UBI to keep people safe. We are now poised for a global discussion about whether we need to work at all, and what kinds of jobs are desirable.
