Probabilistic greedy algorithm solver using magnetic tunneling junctions for traveling salesman problem

Solving a task of optimal route search may be challenging for conventional algorithms. Here, authors use tunable random signals from magnetic tunnel junctions to improve a probabilistic greedy Traveling Salesman Problem solver to better balance exploration and efficiency, and make it applicable for larger problems.

Coinciding spring and autumn frosts have a limited impact on carbon fluxes in a grassland ecosystem

Frost is typically seen as a threat to plants and is expected to lead to decreased ecosystem carbon uptake due to reduced photosynthesis. However, this research shows that spring frosts can actually enhance ecosystem carbon absorption, while autumn frosts behave as expected, prompting an increase in carbon emissions.

Globally consistent influences of seasonal precipitation limit grassland biomass response to elevated CO₂

Rising CO₂ levels have been thought to potentially increase plant growth due to improved fertilization, but such a general effect is spatially and temporally affected by precipitation. Grassland experiments show constraints and increases in the fertilization effect due to seasonal-based precipitation, inferring that any potential plant growth could be mitigated by natural rainfall changes.

Field-experiment constraints on the enhancement of the terrestrial carbon sink by CO₂ fertilization

The northern temperate carbon sink is estimated to increase by 0.64 PgC each year for each increase in atmospheric CO₂ concentrations by 100 ppm, suggests an analysis of data from field experiments at 7 sites constraints.

Iridium single-atom catalyst on nitrogen-doped carbon for formic acid oxidation synthesized using a general host–guest strategy

Single-atom catalysts maximize metal atom efficiency and exhibit properties that can be considerably different to their nanoparticle equivalent. Now a general host–guest strategy to make various single-atom catalysts on nitrogen-doped carbon has been developed; the iridium variant electrocatalyses the formic acid oxidation reaction with high mass activity and displays high tolerance to CO poisoning.

Whole-genome and whole-exome sequencing of bladder cancer identifies frequent alterations in genes involved in sister chromatid cohesion and segregation

Zhiming Cai and colleagues report whole-genome and whole-exome sequencing of 99 paired tumor-normal samples of transitional cell carcinoma of the bladder. They find that 32% of tumors harbor alterations in genes involved in sister chromatid cohesion, including STAG2, ESPL1, NIPBL, SMC1A and SMC3.

Asymmetric effects of daytime and night-time warming on Northern Hemisphere vegetation

Correlations between the maximum and minimum daily temperatures and a vegetation index in the Northern Hemisphere suggest that asymmetric diurnal warming (faster warming of the land surface during the night than during the day) produces several different vegetation and carbon storage effects.

Terrestrial carbon cycle affected by non-uniform climate warming

Feedbacks between the terrestrial carbon cycle and climate change could affect many ecosystem functions and services. A synthesis of global air temperature data reveals non-uniform rates of climate warming on diurnal and seasonal timescales, and heterogeneous impacts on ecosystem carbon cycling.
