Quantum Criticality in life's proteins (Update)

(Phys.org)—Stuart Kauffman, from the University of Calgary, and several of his colleagues have recently published a paper on the Arxiv server titled 'Quantum Criticality at the Origins of Life'. The idea of a quantum criticality, ...

Researchers focus on finding flaws in superbugs' armor

Recent years have seen the rise of bacterial pathogens that have developed resistance to antibiotics. One such superbug, carbapenem-resistant Acinetobacter baumannii (CRAB), kills hundreds of critically ill patients in the ...

How 'pioneer' protein turns stem cells into organs

Early on in each cell, a critical protein known as FoxA2 simultaneously binds to both the chromosomal proteins and the DNA, opening the flood gates for gene activation, according to a new study led by researchers in the Perelman ...

Research shows relationship critical for how cells ingest matter

To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the ...

Biosynthesis captured in motion

(Phys.org) —Chemists have caught molecules in the act of biosynthesis revealing an animated view of how a fundamental piece of cellular machinery operates. The system they observed, a critical metabolic pathway, generates ...

Mechanical forces play major role in regulating cells

Researchers have for the first time demonstrated that mechanical forces can control the depolymerization of actin, a critical protein that provides the major force-bearing structure in the cytoskeletons of cells. The research ...
