The search for renewable energy sources, which include wind, solar, hydroelectric dams, geothermal, and biomass, has preoccupied scientists and policymakers alike, due to their enormous potential in the fight against climate change. A new Tel Aviv University study finds that water vapor in the atmosphere may serve as a potential renewable energy source in the future.

The research, led by Prof. Colin Price in collaboration with Prof. Hadas Saaroni and doctoral student Judi Lax, all of TAU’s Porter School of the Environment and Earth Sciences, is based on the discovery that electricity materializes in the interaction between water molecules and metal surfaces. It was published in Scientific Reports on May 6, 2020.

“We sought to capitalize on a naturally occurring phenomenon: electricity from water,” explains Prof. Price. “Electricity in thunderstorms is generated only by water in its different phases— water vapor, water droplets, and ice. Twenty minutes of cloud development is how we get from water droplets to huge electric discharges—lightning—some half a mile in length.”

On August 2nd, the SpaceX crew dragon that launched on May 30th returned to Earth with the two NASA astronauts it brought to the ISS. With the first American space launch complete, the US has now advanced tremendously in its manned spaceflight capabilities.

Mushroom leather is the latest alternative to animal leather.

Self-healing materials are so widespread that clothes lines and tech companies are already applying them to different products.

Now, a research team at the University of California, Riverside, has developed a new type of self-healing material that is conductive of electricity, highly elastic and almost entirely transparent. The lead researcher has revealed that he drew inspiration from Marvel’s Wolverine character.

Our brains have an upper limit on how much they can process at once due to a constant but limited energy supply, according to a new UCL study using a brain imaging method that measures cellular metabolism.

The study, published in the Journal of Neuroscience, found that paying attention can change how the brain allocates its limited energy; as the brain uses more energy in processing what we attend to, less energy is supplied to processing outside our attention focus.

Explaining the research, senior author Professor Nilli Lavie (UCL Institute of Cognitive Neuroscience) said: It takes a lot of energy to run the human brain. We know that the brain constantly uses around 20% of our metabolic energy, even while we rest our mind, and yet it’s widely believed that this constant but limited supply of energy does not increase when there is more for our mind to process.

Well, they don’t.

Thousands are currently engaged in solving the problem of death. Maybe they’ll succeed, and out of sheer boredom I’ll reread this sentence when I’m 900 years old, reflecting fondly on the first wasted century of my life. In the meantime, billions are going to die—some from disease, some in freak accidents, and a substantial number from what we generally call “old age.” That last sounds like a pleasant way to go, comparatively—a peaceful winding-down. But what exactly does it look like? What does it really mean to die from old age? For this week’s Giz Asks, we reached out to a number of experts to find out.

Astronomers have discovered an activity cycle in another fast radio burst, potentially unearthing a significant clue about these mysterious deep-space phenomena.

Fast radio bursts, or FRBs, are extragalactic flashes of light that pack a serious wallop, unleashing in a few milliseconds as much energy as Earth’s sun does in a century. Scientists first spotted an FRB in 2007, and the cause of these eruptions remains elusive nearly a decade and a half later; potential explanations range from merging superdense neutron stars to advanced alien civilizations.

To advance his vision, last week EIC launched the OPEN100 project, which Kugelmass says will provide open-source blueprints for the design, construction, and financing of a 100-megawatt nuclear reactor. He claims the reactor can be built for $300 million in less than two years, significantly decreasing the per-kilowatt cost of nuclear power.

“Nuclear power isn’t just part of the solution to addressing climate change; it is the solution,” Kugelmass said in a press release. “OPEN100 will radically change the way we deploy nuclear power plants going forward, offering a substantially less expensive and less complicated solution.”

The logic behind the idea is that the biggest barrier to the widespread use of nuclear is the cost of building reactors, which most experts would agree is a major problem for the industry. Kugelmass thinks that’s because we’ve been focused on large, overly complicated reactors that take far too long to build. His solution is to go back to tried and tested pressurized water reactors from the previous century, and bring their cost down even further through standardization and a focus on speedy construction.

MetaRomantism and “Evil”

MetaRomanticism can be thought of as an attempt to reform Romanticism, which seems necessary since it seems to be a constant companion to Modernism and it is especially dangerous when it has access to Modernist tools that is uses while refusing to be rational. Perhaps this explains the horrors of Nazism in the 20th century. Nazis were irrationalist Romantics that stole the Modernist tools of Weimar Germany and nearly destroyed human civilization and they attached themselves to Dharma traditions that sometime support versions of annihilationism.

How can MetaRomanticism help?
