Discovery of new Li ion conductor unlocks new direction for sustainable batteries      (via sciencedaily.com)     Original source 

Researchers have discovered a solid material that rapidly conducts lithium ions. Consisting of non-toxic earth-abundant elements, the new material has high enough Li ion conductivity to replace the liquid electrolytes in current Li ion battery technology, improving safety and energy capacity. The research team have synthesized the material in the laboratory, determined its structure and demonstrated it in a battery cell.

Researchers shed light on river resiliency to flooding      (via sciencedaily.com)     Original source 

Researchers have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors placed in rivers to estimate daily growth in aquatic plants and algae. The researchers then modeled the algal and plant biomass in 143 rivers across the contiguous U.S. to quantify what magnitude of flooding disturbs the biomass and how long the rivers take to recover from floods. Increased understanding of rivers' resiliency is important to maintaining healthy rivers, as human actions can affect flood regimes and change the conditions in rivers for other aquatic life that may rely on algae and plants as a food source.

Do AI-driven chemistry labs actually work? New metrics promise answers      (via sciencedaily.com)     Original source 

The fields of chemistry and materials science are seeing a surge of interest in 'self-driving labs,' which make use of artificial intelligence and automated systems to expedite research and discovery. Researchers are now proposing a suite of definitions and performance metrics that will allow researchers, non-experts, and future users to better understand both what these new technologies are doing and how each technology is performing in comparison to other self-driving labs.

New 'time travel' study reveals future impact of climate change on coastal marshes      (via sciencedaily.com)     Original source 

A new study offers a glimpse into the possible impact of climate change on coastal wetlands 50 years or longer into the future. Scientists are usually forced to rely on computer models to project the long-term effects of rising seas, but an unexpected set of circumstances enabled a real-world experiment along the Gulf Coast.

The role of jellies as a food source in the Arctic winter      (via sciencedaily.com)     Original source 

The Arctic is changing rapidly due to climate change. It is not only affected by increasing surface temperatures, but also by warm water from the Atlantic, which is flowing in more and more -- changing the structures and functions of the ecosystem as it also leads to species from warmer regions, such as sea jellies (also known as jellyfish) arriving in the Arctic. Using DNA metabarcoding, researchers have now been able to demonstrate that these jellyfish serve as food for amphipods on Svalbard during the polar night and thus play a greater role in Arctic food webs than previously assumed.

Tawny owl's pale grey color linked to vital functions ensuring survival in extreme conditions      (via sciencedaily.com)     Original source 

A recent genetic discovery has revealed that the pale grey plumage of the tawny owl is linked to crucial functions that aid the bird's survival in cold environments. As global temperatures rise, dark brown plumage is likely to become more common in tawny owls living in colder areas.

Cold-water coral traps itself on mountains in the deep sea      (via sciencedaily.com)     Original source 

Corals searching for food in the cold and dark waters of the deep sea are building higher and higher mountains to get closer to the source of their food. But in doing so, they may find themselves trapped when the climate changes.

Is the Amazon forest approaching a tipping point?      (via sciencedaily.com)     Original source 

Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.

Biomanufacturing using chemically synthesized sugars enables sustainable supply of sugar without competing with food      (via sciencedaily.com)     Original source 

Researchers have succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained 'anytime, anywhere, and at high rate'. In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field -- including the production of biochemicals, biofuels, and food, where sugar is an essential raw material -- ultimately leading to the creation of a new bio-industry.

Greetings from the island of enhanced stability: The quest for the limit of the periodic table      (via sciencedaily.com)     Original source 

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high atomic numbers up to 118 and are significantly heavier than uranium, the element with the highest atomic number (92) found in larger quantities on Earth. This raises questions such as how many more of these superheavy species are waiting to be discovered, where -- if at all -- is a fundamental limit in the creation of these elements, and what are the characteristics of the so-called island of enhanced stability. In a recent review, experts in theoretical and experimental chemistry and physics of the heaviest elements and their nuclei summarize the major challenges and offer a fresh view on new superheavy elements and the limit of the periodic table.
