Magnets Mimic Gravity’s Guiding Hand for Plants Growing in Space



In the weightless environment of space, plants face unique challenges in orientation and development, particularly due to the absence of gravity, which on Earth plays a crucial role in guiding root growth and shoot direction—a phenomenon known as gravitropism. Recent advancements in plant space biology have revealed a promising approach: using magnetic fields to simulate the guiding influence of gravity, helping plants grow more effectively in microgravity environments.



Scientists have long observed that plant roots naturally grow downward (positive gravitropism), while shoots grow upward (negative gravitropism), responding to Earth’s gravitational pull. However, in the International Space Station (ISS) and other space habitats, this gravitational cue is missing, often resulting in disoriented or inefficient plant growth. To address this, researchers are turning to the phenomenon of diamagnetism—a property of plant tissues that causes them to repel magnetic fields.

By applying strong magnetic gradients, scientists can manipulate the growth direction of plant cells, effectively mimicking the pull of gravity. Experiments with Arabidopsis thaliana and other model plants in space have shown that magnetic fields can steer root growth and promote proper cellular orientation. This magnetically induced tropism functions as a substitute signal, encouraging roots to grow in a particular direction and facilitating nutrient uptake and water transport in a structured manner.

This magnetic approach has tremendous implications for space farming—a critical component of long-duration missions to the Moon, Mars, or deep space. The ability to control plant growth orientation using magnets reduces the reliance on mechanical systems, increases crop reliability, and opens pathways for more autonomous, sustainable space agriculture systems.

Furthermore, understanding how magnetic fields influence plant biology also deepens our knowledge of cellular signaling, hormone distribution (especially auxin), and cytoskeletal responses, potentially leading to applications even in terrestrial agriculture.

In summary, magnets are proving to be a powerful tool in replicating gravity’s role for plant growth in space. By providing directional cues in microgravity, they not only support the development of viable space farming systems but also expand the frontier of bioengineering and space exploration.

Does AI pose a threat to sustainable development?

Image
  The 2025 World Economic Forum, being held in Davos from Monday to Friday under the theme " Collaboration for the Intelligent Age ", is expected to foster a spirit of cooperation and optimism in the digital age in a more sustainable way, despite the different positions of the participants and global uncertainties. Three experts share their views on the issue with China Daily. Projected estimates indicate that advanced artificial intelligence (AI) systems will necessitate over $1 trillion in investments for cloud and enterprise data center infrastructure within the next five years. The AI infrastructure includes servers equipped with graphics processing units (GPUs) or custom accelerators, dedicated networks, storage solutions and specialized facilities, which are all factors that demand significant capital investment. Therefore, evaluating the scale, potential returns and environmental impact of AI's rapid development and application is essential. The rise of AI will si...

Building urban resilience to climate change

Image
  Building Urban Resilience to Climate Change is an essential framework for cities to safeguard their infrastructure, ecosystems, and populations from the increasing threats of climate change. As urban areas grow and climate impacts intensify, it's crucial to develop adaptive measures that not only reduce vulnerabilities but also promote sustainable urban development. This approach involves a variety of strategies, including enhancing green infrastructure, improving water and energy management, promoting low-carbon transportation, and integrating climate adaptation into urban planning. Urban resilience focuses on creating systems that are both adaptable and responsive to climate stressors like heatwaves, flooding, and storms. By prioritizing nature-based solutions such as urban parks, green roofs, and wetlands, cities can mitigate heat island effects, improve air quality, and protect biodiversity. Moreover, integrating sustainable architecture, resilient infrastructure, and effici...

'Our model of cosmology might be broken': New study reveals the universe is expanding too fast for physics to explain

Image
 A recent study has revealed a puzzling discrepancy in our understanding of the universe’s expansion rate, suggesting that our current cosmological models may need a significant overhaul. The crux of the issue lies in the Hubble constant (H₀), a measure of the universe's expansion rate, which appears to differ depending on how it is calculated. For decades, scientists have relied on two primary methods to determine H₀. The first involves observing the cosmic microwave background (CMB), the faint afterglow of the Big Bang, and extrapolating the universe's expansion rate using early-universe physics. The second method uses the local universe, measuring distances to nearby galaxies via "standard candles" like Cepheid variables and Type Ia supernovae. However, these two methods yield conflicting results. The CMB method, based on data from missions like Planck, estimates H₀ to be around 67.4 kilometers per second per megaparsec (km/s/Mpc) . In contrast, local measurements...
