Bacteria release climate-damaging carbon from thawing permafrost
A new study based on scientific sampling of a rusty carbon sink at a permafrost peatland at Sweden has revealed that iron minerals fail to trap organic carbon, a vast source of CO2 and methane not included in global warming forecasts. The study, conducted by researchers from the Universities of Tübingen and Bristol conducted their investigation site at Stordalen mire, Abisko, Sweden appears today [10 December].

’Asynchrony’ important in crop diversity for global food security
Research team with participation of the University of Göttingen analyses ways to ensure food supply Ensuring global food security is a key challenge, especially because of the challenges of climate change and increasing demand from a population expected to reach almost ten billion. A high diversity of crops can help ensure food security in agriculture.

Warm oceans helped first human migration from Asia to North America
Warm oceans helped first human migration from Asia to North America
New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. The international study, led by the University of St. Andrews in Scotland and published Dec. 9 in Science Advances, provides a new picture of the circulation and climate of the North Pacific at the end of the last ice age, with implications for early human migration.

How soil fungi respond to wildfire
How soil fungi respond to wildfire
When wildfires swept through the North Bay in 2017, graduate student Gabriel Smith saw a unique opportunity to study how fire affected his research subject: soil fungi. In the wake of the 2017 North Bay fires, the golden hills of Santa Rosa, California, were unrecognizable. Smoky, seared and buried under ash, the landscape appeared desolate, save for some ghostly, blackened - but still alive - oak trees.

New research project on environmental and safety aspects of stationary energy storage
New research project on environmental and safety aspects of stationary energy storage
By Christoph Pelzl The SABATLE project coordinated by TU Graz focuses on the sustainability and safety of redox flow technologies, which are of immanent importance for the stabilization of the power grid. The increasing use of battery technologies in the mobility sector and in stationary applications has been leading to increasing efforts in battery research of operational safety and battery recycling.

Enhancing Production of Hydropower Plants and Eco-Friendly Electricity Generation
By Helmut Benigni The EU's Green Deal and Austria's efforts to generate the total demand for electricity in Austria based on renewable energies call for a boost of advancement in the hydropower industry. At present, hydropower is the only technology capable of storing and generating renewable electrical energy on a large scale, on-demand and in large capacities.

Index reveals integrity issues for many of the world’s forests
Only 40 per cent of forests are considered to have high ecological integrity, according to a new global measure, the Forest Landscape Integrity Index. The Index was created by 47 forest and conservation experts from across the world, including Professor James Watson of The University of Queensland and the Wildlife Conservation Society.

Hidden symmetry could be key to more robust quantum systems, researchers find
Researchers have found a way to protect highly fragile quantum systems from noise, which could aid in the design and development of new quantum devices, such as ultra-powerful quantum computers. Until we can find a way to make quantum systems more robust, their real-world applications will be limited Shovan Dutta The researchers, from the University of Cambridge, have shown that microscopic particles can remain intrinsically linked, or entangled, over long distances even if there are random disruptions between them.

Social media messages help reduce meat consumption
Sending direct messages on social media informing people of the negative health and environmental impacts of consuming meat has proven successful at changing eating habits, a new study from Cardiff University has shown. The study showed that sending direct messages twice a day through Facebook Messenger led to a significant reduction in the amount of red and processed meat the participants consumed over a 14-day period.

Big data offers promise of better groundwater management in California
To ensure that California's groundwater is sustainably managed in the future and over the long-term, current state definitions of what constitutes groundwater may need to be revised, according to research published this week in PNAS . A McGill University-led research team has analyzed big data of more than 200,000 groundwater samples taken from across the state and found that there are problems with the guidelines used for groundwater management.

Pollution from cooking remains in atmosphere for longer - study
Particulate emissions from cooking stay in the atmosphere for longer than previously thought, making a prolonged contribution to poor air quality and human health, according to a new study. Researchers at the University of Birmingham succeeded in demonstrating how cooking emissions - which account for up to 10 per cent of particulate pollution in the UK - are able to survive in the atmosphere over several days, rather than being broken up and dispersed.

New study allows regional prediction of uranium in groundwater
New study allows regional prediction of uranium in groundwater
Stanford researchers can predict where and when uranium is released into aquifers and suggest an easy fix to keep this naturally occurring toxin from contaminating water sources. Lurking in sediments and surrounding the precious groundwater beneath our feet is a dangerous toxin: uranium. Scientists have long known this and tested for it.

Hydrogen: Electricity Storage of the Future?
By Birgit Baustädter If our energy system is to become more eco-friendly, there is no way to avoid hydrogen as an energy carrier. Researchers around the world are certain of this. Hydrogen is the first element in the periodic table. Not only here does it occupy a prominent place, but also in the discussion about an eco-friendly energy system of the future.

Getting to the bottom of Arctic landslides
Getting to the bottom of Arctic landslides
Erosion of the frozen soil of Arctic regions, known as permafrost, is creating large areas of subsidence, which has catastrophic impact in these regions sensitive to climate change. As the mechanisms behind these geological events are poorly understood, researchers from the Géosciences Paris Sud (GEOPS) laboratory (CNRS / Université Paris-Saclay), in cooperation with the Melnikov Permafrost Institute in Yakutsk, Russia, conducted a cold room 1 simulation of landslides, or slumps, caused by accelerated breakdown of the permafrost.

Archaeologists Explore Secrets of Neolithic Village off Israel’s Coast
UC San Diego archaeologist and Qualcomm Institute (QI) affiliate Thomas Levy and Assaf Yasur-Landau of the University of Haifa in Haifa, Israel and their teams have completed a combined physical and virtual excavation of a Neolithic underwater settlement off Israel's Carmel coast. The expedition could reveal secrets about prehistoric social evolution, climate and environmental change from more than 8,000 years ago.

Disposable or fabric? Here is what matters
Disposable or fabric? Here is what matters
Anyone who wants to protect themselves and others from a COVID-19 infection wears a mask these days. But what about the environmental impact of this mass product, which is used millions of times over? Are masks made of fabric beneficial for the environment or are disposable masks preferable? Empa researchers have examined these questions using life cycle assessments (LCAs) and identified factors for sustainable design.

Time for plan A
By Dr. Daniela Müller Oil, gas and coal were yesterday. Hydrogen could be the key to a green future. Its versatility has made hydrogen a research core area at Graz University of Technology for 50 years. What was that again about hydrogen, symbol H, a chemical element in the periodic table? That made the Hindenburg explode, removes hair dye and powers a few vehicles? Usually very little of what we learnt at school is remembered about it, apart from the oxyhydrogen gas reaction.
