Article Synopsis
- Cytokinin (CK) is a vital plant hormone that regulates various growth processes, including root and shoot development, leaf aging, and stress responses, while also influencing how plants react to pathogens.* -
- Research has shown that CK not only inhibits the growth and virulence of fungal pathogens like Botrytis cinerea but also affects yeast by altering their cell cycle and cellular processes.* -
- The study highlights the significant role of CK in both plant and fungal biology, indicating that this plant hormone may influence interactions between plants and their pathogens through important molecular changes.*
In this paper, we present a single actuator wave-like robot, a novel bioinspired robot which can move forward or backward by producing a continuously advancing wave. The robot has a unique minimalistic mechanical design and produces an advancing sine wave, with a large amplitude, using only a single motor but with no internal straight spine. Over horizontal surfaces, the robot does not slide relative to the surface and its direction of locomotion is determined by the direction of rotation of the motor.

Recent studies have additionally found a correlation between psychological stress, telomere length, and health outcome in humans. However, studies have not yet explored the causal relationship between stress and telomere length, or the molecular mechanisms underlying that relationship.

The frequency of GRV assessment and the intolerant level above which feeding is stopped is controversial.
Objectives: To evaluate a novel approach to EN by allowing high GRV and once-daily assessment that was correlated with the paracetamol absorption test.
A genome-wide screen for Saccharomyces cerevisiae deletion mutants that affect telomere length.
Proc Natl Acad Sci U S A

Telomeres are nucleoprotein structures present at the ends of eukaryotic chromosomes that play a central role in guarding the integrity of the genome by protecting chromosome ends from degradation and fusion. Length regulation is central to telomere function. To broaden our knowledge about the mechanisms that control telomere length, we have carried out a systematic examination of approximately 4,800 haploid deletion mutants of Saccharomyces cerevisiae for telomere-length alterations.
