This week’s science news was led by a spate of climate stories that were as worrying as they were fascinating. Topping the bill are microbes that were woken up after lying frozen in the Alaskan permafrost for up to 40,000 years, only for them to begin churning out carbon dioxide. The ability of these microbes, some of which have been …

Microbes that have been suspended in permafrost for up to 40,000 years could “reawaken” and start churning out greenhouse gases if Arctic summers grow much longer, new research suggests. Under future climate conditions, microbes that have been dormant since the last ice age (2.6 million to 11,700 years ago) may only need a few months to reactivate, according to a …

IN A NUTSHELL 🛰️ Scientists have discovered a turquoise patch in the Antarctic Ocean, visible in satellite images. 🔬 The patch is home to coccolithophores, tiny marine organisms previously thought unable to survive in cold waters. 🌊 Research reveals a dynamic interaction between coccolithophores and diatoms, impacting the ocean’s carbon cycle. 🌍 Findings suggest new potential for plankton in combating …

Trees of all sizes across the Amazon rainforest are getting fatter due to climate change, a new study shows. Rising carbon dioxide (CO2) concentrations in the atmosphere have created a more resource-rich environment for plants in the Amazon, leading to an average 3.3% increase in the circumference of trees at their base every decade since the 1970s, researchers have found. …

And, well, it worked remarkably well. The plants carrying all the genes for the McG cycle weighed two to three times as much as control plants that only had some of the genes. They had more leaves, the leaves themselves were larger, and the plants produced more seeds. In a variety of growing conditions, the plants with an intact McG cycle …

The images were observed at wavelengths of 3.0, 4.26, and 4.7 micrometers, corresponding to prominent emission lines of H2O, CO2 and CO gas, from left to right respectively. 3I/ATLAS is undetected in H2O and CO. By contrast, a bright CO2 …

The accelerating rise in carbon dioxide (CO2) emissions caused by human activity is pushing the planet toward a potential mass extinction, as highlighted in an eye-opening Guardian article published on August 19, 2025. The research features insights from MIT mathematician Daniel Rothman, who delves deep into the Earth’s history, explaining how rapid CO2 increases have triggered mass extinctions in the …

Dinosaur teeth are best known for their bite, yet new research says they also stored a chemical snapshot of prehistoric air. By probing that record, scientists have rebuilt carbon dioxide levels and plant productivity for the age of dinosaurs with a detail once thought impossible. The study comes from Dr. Dingsu Feng and colleagues at the University of Göttingen, the …
