Thermally Driven Dynamic Behaviors in Polymeric Vesicles
Synthetic cells aim to mimic biological form, function, and behavior. In this article, the thermoresponsive properties of the polymer poly(ethylene oxide)‐poly(butylene oxide) are leveraged to create a range of polymeric synthetic cell systems on the nanoscale and microscale which possess a range of biomimetic properties, including cargo release ...

Citrate synthase proteins in extremophilic organisms: Studies within a structure-based model [PDF]
We study four citrate synthase homodimeric proteins within a structure-based coarse-grained model. Two of these proteins come from thermophilic bacteria, one from a cryophilic bacterium and one from a mesophilic organism; three are in the closed and two in the open conformations. Even though the proteins belong to the same fold, the model distinguishes

Supercooling of Alaskan Beetle Larvae as a Winter Survival Strategy
Dehydrated Alaskan beetle larvae in Fairbanks, Alaska, adhere to the bark of trees that are embedded in ice in their natural winter microhabitat (bottom). This enables their bodies to deeply supercool and avoid freezing, in contrast to their fully hydrated summer form (top).

As crucial stages in the plant ontogeny, germination and seedling establishment under adverse conditions greatly determine staple crop growth and productivity. In the context of green technologies aiming to improve crop yield, seed priming is emerging as

The Survival of Water within Extrasolar Minor Planets [PDF]
We compute that extrasolar minor planets can retain much of their internal H_2O during their host star's red giant evolution. The eventual accretion of a water-rich body or bodies onto a helium white dwarf might supply an observable amount of atmospheric hydrogen, as seems likely for GD 362.

Regions of the world permanently below 5 °C harbor significant biodiversity and understudied molecular mechanisms. This knowledge gap originates from the requirement for high‐resolution microscopy methods that maintain cold sample conditions while achieving subcellular resolution.

Extremophiles: a special or general case in the search for extra-terrestrial life? [PDF]
Since time immemorial life has been viewed as being fragile, yet over the past few decades it has been found that many extreme environments are inhabited by organisms known as extremophiles.Knowledge of their emergence, adaptability, and limitations seems to provide a guideline for the search of extra-terrestrial life, since some extremophiles ...

Microbial Ecology of Permafrost Soils: Populations, Processes, and Perspectives
ABSTRACT Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils.
