Catching a new (sea) star      (via sciencedaily.com)     Original source 

Researchers have discovered a new species of sea star (also known as starfish). The discovery came about thanks to collaborative work among researchers, fishers, and aquarium and museum staff. The starfish, which has been named Paragonaster hoeimaruae, belongs to the family Pseudarchasteridae. It is a distinctive red and beige color, with five arms and spans just over 10 centimeters.

Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species      (via sciencedaily.com)     Original source 

A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.

Human-infecting parasite produces sterile soldiers like ants and termites      (via sciencedaily.com)     Original source 

New research finds a tiny freshwater parasite known to cause health problems in humans defends its colonies with a class of soldiers that cannot reproduce. The discovery vaults this species of parasitic flatworm into the ranks of complex animal societies such as ants, bees and termites, which also have distinct classes of workers and soldiers that have given up reproduction to serve their colony.

Tropical plant species are as threatened by climate change as widely feared, study confirms      (via sciencedaily.com)     Original source 

Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.

Novel electrode for improving flowless zinc-bromine battery      (via sciencedaily.com)     Original source 

The flowless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries due to its use of non-flammable electrolytes. However, it suffers from self-discharge due to the crossover of active materials, generated at the positive graphite felt (GF) electrode, to the negative electrode, significantly affecting performance. Now, researchers have developed a novel nitrogen-doped mesoporous carbon-coated GF electrode that effectively suppresses self-discharge. This breakthrough can lead to practical applications of FLZBB in energy storage systems.

Discovery of a hybrid lineage offers clues to how trees adapt to climate change      (via sciencedaily.com)     Original source 

The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.
