A newstudy has introduced a novel method for enhancing somatic embryogenesis (SE) in conifer trees, using small molecules to overcome traditional barriers in asexual propagation. This technique is pivotal for advancing forest production and genetic enhancement by addressing challenges in SE initiation and sustaining embryogenic potential.

A significant study has mapped the genetic complexity of Populus cathayana, an ecologically and economically valuable poplar species. By creating a detailed genome assembly and analyzing genetic variation across diverse wild populations, the research sheds light on the species' evolution and adaptation capabilities, particularly in high-altitude environments. This genetic insight is key for conservation strategies and developing resilient tree species for future forest sustainability.

At a glance: A new study in mice explains how even a single faulty copy of the BRCA1 gene can fuel tumor growth. The findings suggest the dominant 鈥渢wo-hit鈥� hypothesis of cancer development may not tell the full story behind how cancer arises. Study identifies cellular changes that prime cancer-related genes for action and render cells vulnerable to tumor growth. The findings can inform new treatments that block the priming effect to prevent breast cancer formation.

Adolescents in regions with fewer abortion restrictions and those who had an abortion were more likely to have graduated from college, earn higher incomes and have greater financial stability at two time-points over an almost 25-year period. Girls who became teen moms, conversely, were more likely to experience eviction, debt and food insecurity.
