Ancient plant wax reveals how global warming affects methane in Arctic lakes      (via sciencedaily.com)     Original source 

In a new study, researchers examined the waxy coatings of leaves preserved as organic molecules within sediment from the early-to-middle Holocene, a period of intense warming that occurred due to slow changes in Earth's orbit 11,700 to 4,200 years ago. They found that warming potentially could lead to a previously under-appreciated flux in methane emissions from lakes.

Capturing CO2 with electricity: A microbial enzyme inspires electrochemistry      (via sciencedaily.com)     Original source 

Humanity continuously emits greenhouse gases and thereby worsens global warming. Increasing research efforts go into developing strategies to convert these gases, such as carbon dioxide (CO2), into valuable products. CO2 accumulates dramatically over the years and is chemically very stable, thus challenging to transform. Yet, for billions of years, some microbes have actively captured CO2 using highly efficient enzymes. Scientists have now isolated one of these enzymes. When the enzyme was electronically branched on an electrode, they observed the conversion of CO2 to formate with perfect efficiency. This phenomenon will inspire new CO2-fixation systems because of its remarkable directionality and rates.

Plastic cloud: New study analyzes airborne microplastics in clouds      (via sciencedaily.com)     Original source 

Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.

Atlantic walrus more vulnerable than ever to Arctic warming      (via sciencedaily.com)     Original source 

Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.

Novel bacterial proteins from seafloor shine light on climate and astrobiology      (via sciencedaily.com)     Original source 

Researchers have unveiled a remarkable discovery: the identification of novel bacterial proteins that play a vital role in the formation and stability of methane clathrates, which trap gigatons of greenhouse gas beneath the seafloor. These newfound proteins not only suppress methane clathrate growth as effectively as toxic chemicals used in drilling but also prove to be eco-friendly and scalable. This innovative breakthrough not only promises to enhance environmental safety in natural gas transportation but also sheds light on the potential for similar biomolecules to support life beyond Earth.

Desalination system could produce freshwater that is cheaper than tap water      (via sciencedaily.com)     Original source 

Researchers have designed a new solar desalination system that takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren't needed often, meaning the system could potentially produce drinking water at a rate and price that is cheaper than tap water.

Protecting lands slows biodiversity loss among vertebrates by five times      (via sciencedaily.com)     Original source 

Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.

How to save plants from climate change? Just ask them      (via sciencedaily.com) 

Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.

Ecological theory can help explain why segregation persists      (via sciencedaily.com)     Original source 

An ecological theory may help to explain why segregation is so widespread and persistent in US cities, according to a new article. The new way of framing segregation's endurance may provide a useful tool to study and address systemic racism, and could ultimately reveal novel ways of breaking the cycle.

How organic solar cells could become significantly more efficient      (via sciencedaily.com)     Original source 

The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.
