Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs
This article explores the upper lethal temperature for Bobwhite eggs. Results find that thermal tolerances of Northern Bobwhite embryos are high, indicating an adaptation to the naturally occurring temperature extremes in the Bobwhite's environment. However, the results also indicate that high temperatures could have plausibly contributed to the population decline observed in the Bobwhite's semi-arid range.

Environmental filtering of macroinvertebrate traits influences ecosystem functioning in a large river floodplain
Article describes how the biodiversity–ecosystem function hypothesis postulates that higher biodiversity is correlated with faster ecosystem process rates and increased ecosystem stability in fluctuating environments. The authors examined linkages among floodplain wetland habitats, invertebrate communities and their associated traits, and ecosystem function across 60 sites within the floodplain wetlands of the lower Wolastoq, Saint John River, New Brunswick.

Thyroid hormone manipulation influences development of endothermy and hatching in white leghorn chickens (Gallus gallus)
Data collected on metabolic rates, body temperatures, morphology, plasma T3, and hatching of developing chicken embryos and hatchlings. To understand the role thyroid hormones play in hatch timing and development of thermogenic capacity and metabolic rate plasma thyroid hormone levels were manipulated in chicken embryos beginning at 80% development (day 17 of a 21-day incubation) with either a single dose of triiodo-L-thyronine (T3) or the thyroperoxidase inhibitor methimazole (MMI).

The Water-Water Cycle Is Essential for Chloroplast Protection in the Absence of Stress
Article showing that knockdown Arabidopsis plants with suppressed expression of the key water-water cycle enzyme, thylakoid-attached copper/zinc superoxide dismutase (KD-SOD), are suppressed in their growth and development. This article provides e genetic evidence for the importance of the water-water cycle in protecting the photosynthetic apparatus of higher plants from photooxidative damage.

Scaling of axial muscle architecture in juvenile Alligator mississippiensis reveals an enhanced performance capacity of accessory breathing mechanisms
Article describing the anatomy of the trunk muscles, their properties that determine muscle performance (mass, length and physiological cross-sectional area [PCSA]) and investigating their scaling in juvenile Alligator mississippiensis spanning an order of magnitude in body mass (359 g–5.5 kg). Findings support existing anecdotal evidence that crocodilians shift their breathing mechanics as they increase in size.

The refractive index of a single atom experienced by a single photon
Article describes how the refractive index of a system is often viewed as the collective response of a medium to an electromagnetic field. By studying the propagation of a single photon interacting with a two-level atom, the authors examine the dispersion behavior, calculate the phase and group velocity of the photon wave packet, and further analyze the dispersion experienced by the photon.

Long-range current-induced spin accumulation in chiral crystals
Article states that chiral materials, similarly to human hands, have distinguishable right-handed and left-handed enantiomers which may behave differently in response to external stimuli, so for the first time the authors use an approach based on the density functional theory (DFT)+PAOFLOW calculations to quantitatively estimate the so-called collinear Rashba–Edelstein effect (REE) that generates spin accumulation parallel to charge current and can manifest as chirality-dependent charge-to-spin conversion in chiral crystals. The authors reveal that the spin accumulation induced in the bulk by an electric current is intrinsically protected by the quasi-persistent spin helix arising from the crystal symmetries present in chiral systems with the Weyl spin–orbit coupling.
