Single-Cell Analysis Sheds Light on Leukemia Cell Heterogeneity

Chromosomal instability plays a crucial role in the progression of cancer: it shapes the properties of tumor cells and drives the development of therapy resistance. Scientists from the German Cancer Research Center (DKFZ), the Heidelberg Stem Cell Institute HI-STEM and the European Molecular Biology Laboratory (EMBL) used state-of-the-art single-cell analysis methods to analyze the cellular heterogeneity of a specific form of acute myeloid leukemia.

Uncovering the Genetic Basis of Sex Determination in Amborella trichopoda

Although it is a complicated process, plant reproduction is essential to both ecological balance and the food chain. Some plants are hermaphrodites, some are either male or female, and some change sex during their lives.

Novel Approach to Lipid Nanoparticle Engineering

To enhance mRNA distribution, Penn engineers have created an ideal “recipe” for ionizable lipids, which are essential components of lipid nanoparticles (LNPs), the molecules that underlie the COVID-19 vaccines and other cutting-edge treatments.

New Vector Systems Open the Door for Efficient Genetic Modification

A recent breakthrough in biotechnology promises to change the landscape of plant genetic engineering. Imagine a persistent invader-;Agrobacterium-;long used to deliver genes into plants. Despite its historical success, the journey has been fraught with setbacks, especially with crops that launch fierce immune defenses.
