The extensive development in light-emitting diodes (LEDs) in recent years provides an opportunity to positively influence plant growth and biomass accumulation and to optimize biochemical composition and nutritional quality. This study aimed to assess how different light spectra affect the growth, photosynthesis and biochemical properties of Eruca sativa. Therefore two LED lighting modes - red:blue (RB, 1:1) and red:green:blue (RGB, 2:1:2) were compared to the conventional white light fluorescent tubes (WL).

- The study aimed to investigate how low temperatures experienced by rice leaves influence stress responses in the roots and how light conditions affect these processes.
- Researchers exposed rice plants to low temperatures (12°C) while keeping roots at normal temperatures (27°C) and analyzed gene expression changes in the roots.
- Findings revealed that low temperature exposure led to more down-regulated genes, particularly affecting nitrogen metabolism and related signaling, with additional insights from real-time PCR and metabolomics showing that both leaf cold exposure and light conditions impact root stress responses.
Plant infections caused by fungi lead to significant crop losses worldwide every year. This study aims to better understand the plant defence mechanisms regulated by red light, in particular, the effects of red light at night when most phytopathogens are highly infectious. Our results showed that superoxide production significantly increased immediately after red light exposure and, together with hydrogen peroxide levels, was highest at dawn after 30 min of nocturnal red-light treatment.

They are the most common myeloid blood cancers in American adults. The full complement of gene mutations that contribute to the phenotypes or clinical symptoms in MDS is not fully understood.

- Miscarriages are common, occurring in 50-70% of pregnancies, with 1-5% of women experiencing recurrent pregnancy loss (RPL), which is defined as having two or more miscarriages.
- Current understanding of the causes and mechanisms behind RPL is lacking, making reliable diagnostic and preventive methods unavailable.
- The study assessed three placental proteins and found that lower levels of free-β-hCG and PAPP-A, particularly between 9-13 weeks of pregnancy, could serve as effective biomarkers for identifying RPL, suggesting issues with placental function and development.
