Mathematics improve single-cell analysis

A new computational approach allows to account for confounding factors and hidden biological processes in the analysis of single-cell RNA sequence data. Using this method, individual subpopulations and cell types can be identified within heterogeneous cell populations and can be determined more precisely.

Paving a road toward mitochondrial plant cell factories

Scientists have devised a new strategy for selectively delivering genes into the mitochondria of plant cells by using a simple combination of cell-penetrating and mitochondria-targeting peptides. This work lays the groundwork for the rational design of peptide-based gene carriers with the potential to create a new field of 'mitochondria engineering', which could enable the creation of mitochondria-based plant cell factories for the creation of bio-polymers and bio-fuels.

Damaged DNA amplified

Researchers have succeeded for the first time in amplifying gene samples containing DNA adducts while retaining references to these adducts. This type of amplification is a prerequisite for the majority of technologies used by researchers to determine a gene's DNA sequence.
