Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

On 22 May 2019, scientists from Queen's University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a 'vomit comet' flight, where the plane repeatedly climbs to 8km in a steep ...

Researchers from Karolinska Institutet have discovered a new molecular mechanism by which cancer cells safeguard themselves from oncogene-induced replication stress and propose a strategy to ...

Researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in host cells. University ...

Despite tremendous efforts by the global scientific community to curb the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by developing more efficient testing protocols, ...

A viral replicon system suited to the stable replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), without cytopathic effects, has been reported recently in a study ...

The current model of replication-dependent (RD) histone biosynthesis posits that RD histone gene expression is coupled to DNA replication, occurring only in S phase of the cell cycle once DNA ...

Digitized drawing from Heng’s work with grade school students at Paxton Keeley and Mill Creek elementary schools. The m7G “hat” allows HIV to access a cell’s global translation pathways need for mRNA ...
