Scientists at The Ohio State University have developed a new device known as Underwater Zooplankton Enhancement Light Array (UZELA), which will help promote more feeding sources for coral restoration.

UZELA is a submersible, programmable light that can be deployed at a site for up to six months on one battery. If the devices need any maintenance, trained divers can easily handle this. UZELA turns on for about one hour per night, and the emitted light helps increase concentrations of zooplankton while minimizing artificial light disruption to other marine species. This allows corals more feeding opportunities, according to the scientists.

The team tested the device near two native corals in Hawaii, Montipora capitata and Porites compressa. After running the UZELA, the amount of locally concentrated zooplankton increased seven-fold, while the coral feeding rates increased between 10- and 50-fold. The scientists published their findings in the journal Limnology and Oceanography: Methods.

“Coral reefs house one-third of all marine species, yet occupy less than 1% of the ocean,” Andréa Grottoli, lead author of the study and earth sciences professor at The Ohio State University, said in a statement. “They are disproportionately responsible for ocean health and we’re at risk of losing them.”

Coral reefs are threatened by extreme heat stress. Last year, the U.S. National Oceanic and Atmospheric Administration (NOAA) warned that the world was experiencing its fourth mass coral bleaching event, which is when the corals lose symbiotic algae that provide nutrients to the corals because of extreme heat. From February 2023 to April 2024, NOAA found that about 60.5% of global corals had experienced bleaching.

Bleaching can make coral more vulnerable to disease and die-off, and water temperature and conditions must return to normal for algae to return to coral. However, by concentrating zooplankton near coral, they can feed and obtain nutrients to help their road to recovery.

With such great threats facing coral reefs, the study authors noted that UZELA is only one temporary solution to the plight of reef systems. For now, it could work in some of the most vulnerable and important reef systems to boost restoration efforts until more substantial actions are taken to minimize stressors that trigger bleaching.

“Think of it as a band-aid for about a couple decades,” Grottoli said. “It can protect some corals in some places, sometimes.”

Currently the UZELA devices are made by hand, but the scientists are collaborating with a local engineering company to redesign UZELA for scalability. The updated device could be ready within one to three years, according to Grottoli.

“We are not mitigating climate change fast enough to save coral, and UZELA is not going to instantly save coral reefs,” Grottoli said. “But it is an exciting solution that will buy us time as we work toward a more sustainable environment.”

First paper ever alert! We found that locally increasing zooplankton using the Underwater Zooplankton Enhancement Light Array (UZELA) can increase feeding in two Hawaiian coral species up to tenfold. aslopubs.onlinelibrary.wiley.com/doi/10.1002/…

Earth911 Inspiration: Life Is An Endless Equation

Published

on

As humanity grows in its understanding of the complexity of living systems, we will encounter many opportunities to restore nature. Taoist author Deng Ming-Dao wrote in his daily meditations, 365 Tao, that “Life is one endless equation of darkness, brilliance, fragrance, color, sound, and sensation.”

Imagine the joys of nature, live them fiercely and gently in your daily life, and the world can grow anew.

Best of Sustainability In Your Ear: Author Topher McDougal Asks If Earth Is Evolving A Planetary Consciousness

What if Earth is developing a planetary collective intelligence emerging from the convergence of ecological crisis, new global information systems, and the data-crunching capabilities of artificial intelligence? This provocative question drives economist Topher McDougal’s book, Gaia Wakes: Earth’s Emergent Consciousness in an Age of Environmental Devastation. On this episode of Sustainability In Your Ear, we explore McDougal’s sweeping theory that our planet may be in the early stages of developing what he calls a “Gaiacephalos”—a planetary consciousness that could fundamentally reshape humanity’s role in the global ecosystem. McDougal opens his book with a striking metaphor from Star Trek: The Next Generation, where the Enterprise’s computer systems flicker into sentience, its emerging “personality” acting out disagreements in the holodeck that nearly destroy the ship. That episode, McDougal argues, mirrors our current moment. As environmental devastation accelerates and technologies become increasingly networked, we may be witnessing the birth pangs of a planetary intelligence that could guide us toward survival or react chaotically to the damage humans have caused.

Author Topher McDougal discusses his new book, Gaia Wakes, on this episode of Sustainability in Your Ear.

Building on James Lovelock’s Gaia hypothesis, which views Earth as a self-regulating living system, McDougal explores the profound and unsettling implications of Gaiacephalos. What is humanity’s role? Noting a paradox in human development, that societies have become increasingly peaceful at the expense of massive environmental degradation, McDougal discusses how concepts like “progress” and “free will” might change in a world governed by an emergent planetary intelligence. Drawing on ancient myths—from Hopi legends to the Tower of Babel—McDougal uses traditional stories as lenses for understanding global transformation. Throughout our conversation, he repeatedly references the work of René Descartes and how his mind-body split has defined Western thinking since the Enlightenment. He argues that this mechanistic view prevents us from understanding emerging systems holistically—whether we’re talking about AI, collective intelligence, or planetary consciousness. We keep separating the physical system that performs calculations from the experience of thought itself, missing the integrated whole. Consequently, becoming “indigenous to our times” offers a path forward. Rather than appropriating Indigenous ways of life, he suggests we need to learn how to live fully in relationship with our current systems and places. True indigeneity means understanding our role within larger systems and, as the apex predator currently destroying the ecosystem we depend on, being thoughtful about our interactions within that system.

Gaia Wakes poses challenging questions about whether we’re building toward a benign planetary intelligence or heading toward dystopian risks. McDougal doesn’t offer easy answers, but he provides a framework for thinking about how technological trends—from AI and smart infrastructure to global information networks—might be assembling the components of a planetary brain. The book is part speculative theory, part analytical deep dive. It challenges readers to think beyond traditional boundaries between nature and technology, individual and collective intelligence, human agency and planetary systems.

Oops, We Did It Again: 2025 Second Hottest Year On Record

Published

on

Yes, we resorted to a Britney Spears reference, but this isn’t cute anymore. The World Meteorological Organization confirmed that 2025 was the second-hottest year on record, with average global temperatures reaching 1.47°C above pre-industrial levels. Only 2024’s record-breaking heat was worse.

The past 11 years are now the warmest 11 years in the 176-year history of temperature records.

What is especially concerning about 2025 is that it occurred during La Niña, a natural Pacific cooling pattern that usually brings lower temperatures. This time, it did not help. Climate scientist James Hansen reportsthat global warming is now speeding up by 0.31°C per decade, and he predicts we will pass the +1.7°C mark by 2027.

For the first time, the average temperature from 2023 to 2025 was higher than the 1.5°C limit set by the Paris Agreement. Scientists say this threshold is crucial to prevent severe and lasting climate impacts for people alive today. In 2024, atmospheric CO₂ reached 423.9 parts per million, which is 53% higher than pre-industrial levels.

Meanwhile, the cascade of extreme weather continues: heat waves are now 10 times more likely than a decade ago, Arctic sea ice hit its lowest winter maximum on record, wildfires are devastating Greece and Turkey, and typhoons are forcing mass evacuations across Southeast Asia.

“Each year above 1.5 degrees will hammer economies, deepen inequalities and inflict irreversible damage,” said WMO Secretary-General Celeste Saulo.

The measurements are undeniable. The data cannot be denied. Still, the United States government under the Trump administration is suppressing climate information and reversing clean energy policies to support coal, oil, and gas. COP30 ended without a clear promise to phase out fossil fuels.

As the planet cooks in industrial era pollution, playing politics with climate science is beyond irresponsible. It’s dangerous.
