What happens when humanity begins living in space, building larger space stations, and creating a purely space based economy. Space drones will deliver goods between stations, farming stations will grow food, and space hotels will host celestial events and viewing parties for eclipses and welcoming parties for spaceships returning from Mars.

This sci-fi documentary takes a look at the future of space stations and space technology, starting with the retiring of the International Space Station, and ending with the construction of the largest rotating ring world space station, with its own atmosphere and lakes that evaporate creating clouds and rain.

Scientists at the University of Sydney have developed a gene-editing tool with greater accuracy and flexibility than the industry standard, CRISPR, which has revolutionized genetic engineering in medicine, agriculture and biotechnology.

SeekRNA uses a programmable ribonucleic acid (RNA) strand that can directly identify sites for insertion in genetic sequences, simplifying the editing process and reducing errors.

The new gene-editing tool is being developed by a team led by Dr. Sandro Ataide in the School of Life and Environmental Sciences. Their findings have been published in Nature Communications.

“One of the long-term aims of the research is to make better tailored foods for astronauts, as well as other people who are in isolated environments, to increase their nutritional intake closer to 100%,” said Dr. Julia Low.

Does food smell and taste different to astronauts in space and what steps can be taken to mitigate this in the future? This is what a recent study published in the International Journal of Food Science & Technology as an international team of researchers investigated how food aromas could be altered to amplify food taste. This study holds the potential to help researchers improve diets for isolated individuals, specifically in space or nursing home residents.

For the study, the researchers analyzed food odor perception of vanilla, almond, and lemon among 54 participants between 18 to 39 years old in a neutral setting and a virtual reality (VR) simulation of the International Space Station (ISS) with a key trait being they had no history of vertigo or motion sickness. The participants were asked to rate the potency of the aromas in both settings to compare any differences between the two environments.

A research team led by the Department of Energy’s Oak Ridge National Laboratory has bridged a knowledge gap in atomic-scale heat motion. This new understanding holds promise for enhancing materials to advance an emerging technology called solid-state cooling.

An environmentally friendly innovation, solid-state cooling could efficiently chill many things in daily life from food to vehicles to electronics — without traditional refrigerant liquids and gases or moving parts. The system would operate via a quiet, compact and lightweight system that allows precise temperature control.

Although the discovery of improved materials and the invention of higher-quality devices are already helping to promote the growth of the new cooling method, a deeper understanding of material enhancements is essential. The research team used a suite of neutron-scattering instruments to examine at the atomic scale a material that scientists consider to be an optimal candidate for use in solid-state cooling.

A long-term study since 1929 has revealed significant insights into barley’s evolution, showing its adaptation to different environments and the substantial impact of natural selection. This research underscores the limitations of evolutionary breeding and highlights the need for further exploration to enhance crop yields.

Utilizing one of the world’s oldest biological experiments, which commenced in 1929, researchers have revealed how barley, a major crop, has been influenced by agricultural pressures and its evolving natural environment. These findings highlight the significance of long-term studies in comprehending the dynamics of adaptive evolution.

The survival of cultivated plants after their dispersal across different environments is a classic example of rapid adaptive evolution. For example, barley, an important neolithic crop, spread widely after domestication over 10,000 years ago to become a staple source of nutrition for humans and livestock throughout Europe, Asia, and Northern Africa over just a few thousand generations. Such rapid expansion and cultivation have subjected the plant to strong selective pressures, including artificial selection for desired traits and natural selection by being forced to adapt to diverse new environments.

A new paper finds that combining photovoltaics with crop farming can result in revenue gains over the life of a PV system at a diverse range of locations in the United Kingdom. Researcher Aritra Ghosh tells pv magazine that the benefits of agrivoltaics are ‘multifaceted.’

The Maximum Absorbency Garment (MAG)—that collects urine and feces during extravehicular activities (EVAs) that last up to 8 h. Such exposure to waste for prolonged periods of time contributes to hygiene-related medical events, including urinary tract infections and gastrointestinal distress. Historically, prior to using the MAG, astronauts have limited their food intake or eaten a low-residue diet before embarking on physically demanding spacewalks, reducing their work performance index (WPI) and posing a health risk. Furthermore, the current 0.95 L In-suit Drink Bag (IDB) does not provide sufficient water for more frequent, longer-range spacewalks, which carry greater potential for contingency scenarios requiring extended time away from a vehicle.

The neurons that produce a sick feeling and food aversion are distinct from those that induce a feeling of fullness.

Next-generation anti-obesity drugs such as Wegovy can melt away weight — but they can also cause intolerable nausea. Now scientists have pinpointed a brain pathway that is involved in this common side effect, raising the prospect of effective weight-loss drugs that don’t make people sick¹.

There are biological underpinnings to aging—and so researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets.
