Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source.

The model developed by researchers at the University of Michigan could aid in the design of the capsule, minimizing the energy lost while trying to ignite the reaction that makes stars shine. In addition, the model could help other engineers who must manage the mixing of fluids after a shock wave passes through, such as those designing supersonic jet engines, as well as physicists trying to understand supernovae.

“These move outward from the collapsing star, populating the universe with the materials that will eventually become nebulae, planets and even new stars—and inward during fusion implosions, disrupting the stability of the burning fusion fuel and reducing the efficiency of the reaction,” said Michael Wadas, a doctoral candidate in at U-M and corresponding author of the study.

A pair of harvesting robots are picking raspberries in Portugal, demonstrating the ability of tech to help combat seasonal labor shortages.

Sea of Green is a marijuana growing method in which numerous little plants are produced in close proximity per square meter of area. The advantage of developing this way is that plants spend less time in the vegetation stage while still creating as many bud sites per area volume. Buds mature faster in SOG, resulting in an additional yield yearly.

Furthermore, clones are typically used in SOG. This guarantees that all of the plants have the same characteristics (growing speed and height.) and that your SOG grows to have a lovely even canopy. You can also grow weed seeds for sale; however, only seeds from the same strain should be used. Avoid tall, lanky Sativa if possible. Also, keep your plants at the same level beneath your grow lights to maintain consistent development.

How many plants can you expect to grow per square foot with SOG?

The size of your growing space determines the number of cannabis plants per square foot that SOG can cultivate. After that, you can determine how many plants you want and the size of the containers. Most experts, however, advise growing up to one plant per square foot or two at most. Cultivating one SOG plant per square foot equals 10–11 plants per square meter (1 square meter = roughly 10.75 square feet). You should also avoid using pots with capacities of less than three liters.

Including space.

The DARPA Biomanufacturing: Survival, Utility, and Reliability beyond Earth (B-SURE) program aims to address foundational scientific questions to determine how well industrial bio-manufacturing microorganisms perform in space conditions. http://ow.ly/3Nya50On2za

In January 2019, China made history by becoming the first country to land a spacecraft on the far side of the moon. As part of this mission, the Chang’e-4 lunar rover carried a small biosphere with six living organisms, including cotton seeds. While the other plants in the biosphere died quickly, the cotton seeds produced a small plant, which grew two leaves before it died. Researchers then created a 3D simulation of the cotton plant using data from the experiment, which revealed that the cotton plant grew much better than expected before it died from the cold.

This experiment marked the first time that humans have attempted to grow plants on the moon. Growing plants in space is an important part of NASA’s vision of long-term space travel. If astronauts are to embark on missions lasting months or years, they will need fresh produce to supplement their diet. While vitamins and other supplements are effective for short-term missions, the nutrients in supplements and ready-made meals can break down over time. Radiation in space can speed up this process. In addition, fresh vegetables would give astronauts more nutrients and improve the taste of their food. Furthermore, growing plants in space would enable astronauts to have access to fresh, uncooked food, reducing their reliance on pre-cooked meals.

However, growing plants in space is not just about ensuring astronauts have access to fresh food. NASA is also interested in how growing plants can impact the psychological well-being of astronauts. Studies have shown that access to plants and green spaces can have a positive impact on mental health, and astronauts on the International Space Station have reported that fresh flowers and gardens can create a beautiful atmosphere and make them feel more connected to Earth.

The James Webb Space Telescope has helped astronomers detect the first chemical signs of supermassive stars, “celestial monsters” blazing with the brightness of millions of Suns in the early universe.

So far, the largest stars observed anywhere have a mass of around 300 times that of our Sun.

But the supermassive star described in a new study has an estimated mass of 5,000 to 10,000 Suns.

Stability AI, the AI startup behind the text-to-image model Stable Diffusion, this week announced the release of StableStudio, an open source version of DreamStudio, Stability AI’s commercial AI-powered design suite.

In a blog post, Stability AI writes that it hopes to “foster a project [that] can outpace anything developed by a single company,” alluding to recent investments in the generative AI space from tech giants like Microsoft, Google and Amazon.

“We believe the best way to expand upon that impressive reach is through open, community-driven development rather than a private iteration of a closed-source product,” Stability AI said. “Our goal is to work with the broader community to create a world-class user interface for generative AI [that] users fully control.”
