Seawater temperatures are rising rapidly and severely due to climate change, negatively affecting coral reef communities. The persistence of coral populations depends on their success during the early life stages. Thermal conditioning during the larval stage can increase coral larvae's ability to tolerate high temperatures in subsequent stages. We studied the response of resistant larvae of Acropora tenuis to thermal stress to increase their thermal tolerance during the juvenile stage. Larvae were exposed to ambient (∼26 °C) and thermal stress (∼31 °C) temperatures. Then, settlement success on preconditioned tiles was determined. After 28 days at ambient temperature, the juveniles were exposed to thermal stress for 14 days, and their survival was assessed. Our results showed that thermal stress in the larval stage did not alter the thermal tolerance of juveniles, and they could not acclimate to heat stress. As a result, the summer's heat waves could potentially threaten their resilience.

This study investigated the single and combined effects of environmental heat stress and physical exercise on executive function (EF) performance, prefrontal cortex oxygenation, thermoregulatory responses and subjective perceptions. Sixteen subjects participated in four experimental sessions: two under moderate environmental conditions (23 °C), with and without physical exercise (R23, E23), and two under hot environmental conditions (35 °C), with and without physical exercise (R35, E35). In each session, participants completed EF tasks before and after 1 h of passive rest or 45 min of moderate-intensity cycling followed by 15 min of rest.

This study presents a novel optoporation technique using a titanium-coated TiO microstructure (TMS) device activated by an infrared diode laser for highly efficient intracellular delivery. The TMS device, fabricated with 120 nm titanium coating on a titanium dioxide (TiO) microstructure containing microneedles (height ∼2 μm and width ∼4.5 μm), demonstrates enhanced biocompatibility and thermal conductivity compared to the conventional TiO microstructure (MS).

Sea anemones play a crucial role in marine ecosystems. Recent studies have highlighted their physiological and ecological responses to thermal stress. Therefore, our objective was to perform a proteomic analysis of sea anemones in the Gulf of Mexico, subjected to thermal stress, to understand whether these organisms activate specific processes to resist increased temperature.

Self-organization realizes various nanostructures to control material properties such as superconducting vortex pinning and thermal conductivity. However, the self-organization of nucleation and growth is constrained by the growth geometric symmetry. To realize highly controlled three-dimensional nanostructures by self-organization, nanostructure formation that breaks the growth geometric symmetry thermodynamically and kinetically, such as tilted or in-plane aligned nanostructures, is a challenging issue.

Temperature control is crucial for live cell imaging, particularly in studies involving plant responses to high ambient temperatures and thermal stress. This study presents the design, development, and testing of two cost-effective heating devices tailored for confocal microscopy applications: an aluminum heat plate and a wireless mini-heater. The aluminum heat plate, engineered to integrate seamlessly with the standard 160 mm × 110 mm microscope stage, supports temperatures up to 36°C, suitable for studies in the range of non-stressful warm temperatures (e.
