Quantum Entanglement harvesting in a vacuum

Posted by in categories: particle physics, quantum physics, space

Circa 2016

Entanglement is an extremely strong correlation that can exist between quantum systems. These correlations are so strong that two or more entangled particles have to be described with reference to each other, even though the individual objects may be spatially separated.

Grain of dust found from dead star that predates the Sun

Posted by in category: space

At a glance, meteorites might only be marginally more interesting than regular old rocks, but look closely and they can tell us stories of ancient stars and long-lost planets. One of these stories has now been uncovered in a piece of space rock retrieved from Antarctica, containing grains from a stellar explosion that predates the Sun.

Planting 1.2 Trillion Trees Could Cancel Out a Decade of CO2 Emissions, Scientists Find

Posted by in categories: climatology, space, sustainability

There is enough room in the world’s existing parks, forests, and abandoned land to plant 1.2 trillion additional trees, which would have the CO2 storage capacity to cancel out a decade of carbon dioxide emissions, according to a new analysis by ecologist Thomas Crowther and colleagues at ETH Zurich, a Swiss university.

The research, presented at this year’s American Association for the Advancement of Science conference in Washington, D.C., argues that planting additional trees is one of the most effective ways to reduce greenhouse gases.

Trees are “our most powerful weapon in the fight against climate change,” Crowther told The Independent. Combining forest inventory data from 1.2 million locations around the world and satellite images, the scientists estimate there are 3 trillion trees on Earth — seven times more than previous estimates. But they also found that there is abundant space to restore millions of acres of additional forests, not counting urban and agricultural land.

Squid skin inspires creation of next-generation space blanket

Posted by in categories: innovation, space

Drawing design inspiration from the skin of stealthy sea creatures, engineers at the University of California, Irvine have developed a next-generation, adaptive space blanket that gives users the ability to control their temperature. The innovation is detailed in a study published today in Nature Communications.

Researchers find ice feature on Saturn’s giant moon

Posted by in categories: materials, space

Rain, seas and a surface of eroding organic material can be found both on Earth and on Saturn’s largest moon, Titan. However, on Titan it is methane, not water, that fills the lakes with slushy raindrops.

Purdue pursues smart, resilient space habitats

Posted by in categories: habitats, space

To help put the first generation of space colonists on the right footing, Purdue University’s Resilient ExtraTerrestrial Habitats (RETH) Institute is building a one-quarter-scale space habitat similar to ones that may one day be built on the Moon and Mars. It is hoped habitats boasting a combination of “resilience, intelligence, and autonomy” will stand up to the many hazards space can throw at them.

Jose Cordeiro is promoting the development of rejuvenation biotechnologies in Spain and the integration of Latin American immigrants into Spain’s aging society to maintain the country’s productivity. He was at the recent Undoing aging conference in Berlin and gave us an interview about his political goals.

At Undoing Aging 2019, jointly organized by SENS Research Foundation and Forever Healthy Foundation, there was a session focused on the ways to make healthy life extension and medical progress a greater part of the global agenda. Among the speakers there was Jose Cordeiro, the vice chair of Humanity Plus, director of The Millennium Project, fellow of the World Academy of Art and Science, and board member of the Lifeboat Foundation.

This Martian Greenhouse Concept Just Won a NASA Award

Posted by in categories: food, space

The hydroponic structure could allow astronauts to grow their own food on the desolate Martian surface. It’d cultivate up to eight food crops could be grown inside a rotating system that could serve up 3100 calories per day for four astronauts over a 600 day excursion to the Red Planet.

It’d grow kale, soy, sweet potato, potato, broccoli, strawberry, wheat, and chufa. A massive tank filled with a nutrient solution under the ceiling feeds a circular system of crop trays with the help of gravity. LEDs make sure that the plants get enough sunlight.
