Auxin accumulation at the inner bend of seedling leads to growth inhibition rather than stimulation as in other plant tissues. Increased levels of the hormone auxin usually promote cell growth in various plant tissues. Chinese scientists together with researchers from the Institute of Science and Technology Austria IST Austria have now shown that in special areas of the seedling, increased auxin levels trigger a different gene expression pathway leading to growth inhibition. Increased auxin accumulation blue areas in the concave side of the apical hook of Arabidopsis thaliana. The discovery, published in the journal Nature, helps to explain the formation of the typical bend or so called apical hook that helps the seedling to break through the soil following germination. Varied auxin concentrations mediate distinct developmental outcomes in different plant tissues.

Famed American actress Demi Moore at last tells her own story in a surprisingly intimate and emotionally charged memoir. For decades, Demi Moore has been synonymous with celebrity. From iconic film roles to high-profile relationships, Moore has never been far from the spotlight—or the headlines.

Throughout her rise to fame and during some of the most pivotal moments of her life, Demi battled addiction, body image issues, and childhood trauma that would follow her for years—all while juggling a skyrocketing career and at times negative public perception. As her success grew, Demi found herself questioning if she belonged in Hollywood, if she was a good mother, a good actress—and, always, if she was simply good enough. As much as her story is about adversity, it is also about tremendous resilience.
