Deep-Sea Microorganism Found to Break Down Plastic Naturally

 

In a groundbreaking discovery that could transform the global fight against plastic pollution, a team of marine biologists has identified a deep-sea microorganism capable of naturally breaking down plastic waste. Found nearly 6,000 meters below sea level, this organism thrives in one of the most extreme environments on Earth—high pressure, low temperature, and complete darkness. Yet remarkably, it has evolved a biochemical mechanism that allows it to digest some of the most persistent forms of plastic, including polyethylene and polypropylene.

Scientists discovered the microorganism while analyzing sediment samples collected from the Mariana Trench and surrounding deep-sea ecosystems. During laboratory analysis, researchers observed that certain plastic fragments placed in controlled environments showed significant degradation within weeks, far faster than the hundreds of years plastic typically requires to break down. Genetic sequencing later confirmed the presence of specialized enzymes similar to PETase and MHETase—enzymes previously identified in land-based bacteria but never before seen in deep-ocean life.

What makes this discovery especially significant is the organism’s ability to break down plastic at extremely low temperatures. Most plastic-degrading enzymes function only in warm environments, making large-scale deployment difficult. However, this deep-sea enzyme works efficiently in cold, dark conditions, opening potential for industrial applications in marine cleanup devices, cold-temperature recycling facilities, and bioengineered waste-management systems.

Environmental scientists are cautiously optimistic. While the discovery offers a promising pathway for biotechnological solutions, they emphasize that it is not a replacement for reducing plastic production or improving global waste management systems. Nevertheless, identifying a naturally occurring species with such high plastic-degradation potential marks a major step forward in combating marine pollution.

Currently, a multidisciplinary team of oceanographers, geneticists, and biotechnologists is studying whether the microorganism’s enzymes can be replicated or enhanced through synthetic biology. If successful, these enzymes could accelerate plastic degradation from centuries to months, offering hope for cleaner oceans and a more sustainable future.

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...
