The melting of Greenland: A climate challenge with major implications for the 21st century
The melting of Greenland is accelerating, with an estimated loss of between 964 and 1735 gigatons of ice per year by 2100 in a scenario of high greenhouse gas emissions (SSP585), according to three regional climate models. This melting will lead to a.....»»
Is there enough land on Earth to fight climate change and feed the world?
Capping global warming at 1.5°C is a tall order. Achieving that goal will not only require a massive reduction in greenhouse gas emissions from human activities, but also a substantial reallocation of land to support that effort and sustain the bios.....»»
Marine heat waves" hidden depths revealed in study
As the ocean warms under climate change, a better understanding of how damaging marine heat waves develop and last may help scientists predict them more accurately and forecast their impacts on marine ecosystems......»»
China experiences reduction in food system inequality and carbon footprint alongside economic development
Humans have persistent food needs that trigger considerable greenhouse gas emissions, varying significantly by region. However, the greenhouse gas (GHG) footprint and inequality in the food system are not well assessed within countries......»»
Why an Offline Nuclear Reactor Led to Thousands of Hospital Appointments Being Canceled
Radioisotopes are a vital resource for imaging patients’ organs and tumors—but these unstable elements also suffer from an unstable supply chain......»»
Submarine canyon plastic accumulation is driven by turbidity currents, simulation study shows
Plastic pollution is an ever-pressing concern for the health of our ocean ecosystems and their inhabitants, with estimates of over 10 million metric tons of plastic litter entering the marine realm each year. While evocative images often highlight su.....»»
Threads testing option to let users choose which feed they want to see by default
As we reported last week, Threads has begun to globally roll out Custom Feeds based on specific topics. And Meta seems to be really listening to users recently, as the company is now testing an option to let users set which feed they want to see by d.....»»
Oil spill still contaminating sensitive Mauritius mangroves three years on
Three years after the bulk carrier MV Wakashio ran aground on a coral reef off Mauritius, spilling around 1,000 tons of a new type of marine fuel oil, Curtin University-led research has confirmed the oil is still present in an environmentally sensiti.....»»
New mechanism in bacterial DNA enzyme opens pathways for antibiotic development
Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Center have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic target. This enzyme, present in bacteria but absent i.....»»
Managing forests with smart technologies
Deforestation has remained a significant issue globally, with primary forests contributing to 16% of the total tree cover loss in the last two decades, driven by climate change and intensive human activity. This threatens natural resources, biodivers.....»»

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas......»»
In Patagonia, more snow could protect glaciers from melt—but only if greenhouse gas are curbed emissions soon
In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, a new study in Scientific Reports from INSTAAR postdoc Matthias Troch suggests that this protective effect might be pushed up against i.....»»
Non-genetic reprogramming method to restore sweat gland function shows promise for burn victims
Sweat glands are vital for regulating body temperature, maintaining fluid balance, and supporting skin health. Yet, extensive skin injuries, such as burns, often result in the loss of these glands, leaving patients vulnerable to overheating, dehydrat.....»»
Building climate resilient cocoa farming in West Africa
Agroforestry systems, which integrate trees and shrubs into farming, are vital to achieving sustainable cocoa production in West Africa where 70% of the world cocoa is produced. Climate change induced drought means that it is ever more critical to ad.....»»
Satellite data and algorithms reveal which ships emit excessive nitrogen
Ships are still emitting too much nitrogen oxide. Until now, it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. K.....»»
