Investigating the possibility of using Asteroid material to Grow Edible Biomass for Astronauts
A team of engineers and planetary scientists at Western University’s Institute for Earth and Space Exploration, in Canada, has found that it might be possible to produce food for space travelers by feeding bacteria asteroid material, resulting in the growth of an edible biomass.
In their paper published in the International Journal of Astrobiology, the group describes how they tested the idea by calculating how much asteroid material would be needed and what they found.
Prior research has shown that future spacecraft traveling to remote parts of the solar system or beyond could not possibly hold enough food to sustain astronauts. Such craft could not support the growth of enough food onboard, either.
Colossal Room Temperature Nonreciprocal Hall Effect
The Attosecond Science group at the Center for Free-Electron Laser Science has developed a novel light source capable of producing extremely short pulses for the investigation of UV-induced molecular dynamics with unprecedented temporal resolution. Scientists from the University of Hamburg and from DESY describe their unique observations in an article published in Nature Communications.

Mysterious 165-Million-Year-Old Minerals Found on Easter Island Defy Plate Tectonics
Easter Island consists of several extinct volcanoes. The oldest lava deposits formed some 2.5 million years ago on top of an oceanic plate not much older than the volcanoes themselves. In 2019, a team of Cuban and Colombian geologists left for Easter Island to accurately date the volcanic island. To do so, they resorted to a tried-and-tested recipe: dating zircon minerals. When magma cools, these minerals crystallize. They contain a bit of uranium, which ‘turns’ into lead through radioactive decay.
Because we know how fast that process happens, we can measure how long ago those minerals formed. The team from Colombia’s Universidad de Los Andes, led by Cuban geologist Yamirka Rojas-Agramonte, therefore went in search of those minerals. Rojas-Agramonte, now at the Christian Albrechts-University Kiel, found hundreds of them. But surprisingly, not only from 2.5 million years old, but also from much further back in time, up to 165 million years ago. How could that be?
