Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

New Methods Increase Understanding of How Bacteria Manage DNA

New analytical methods developed at Baylor College of Medicine and collaborating institutions have increased our understanding of how bacteria manage DNA.

RNA Network Controls Cell Wall Remodeling in Apple Embryogenesis

Somatic embryogenesis is a powerful route for plant regeneration, transformation, and breeding, but one major question has remained unresolved: how highly differentiated cells regain the capacity to divide and develop like embryos.

New Strategy Enables 3D Tissue Engineering Without the Use of Scaffolds

Biological tissues have a remarkable ability to organize and change shape, driven by forces generated by their own cells. One of the major challenges in bioengineering is harnessing this natural behavior to design synthetic living materials capable of adopting predetermined shapes. However, precisely controlling how a tissue behaves and directing its internal forces to adopt the desired shape remains a significant scientific challenge.

Scientists Uncover How "Sorting Hubs" Clear Damaged Proteins From Cells

Inside every cell, a cleanup operation runs around the clock. Proteins are constantly damaged by wear and tear. Some can be repaired, while others must be dismantled and recycled. When this system fails, damaged proteins accumulate in clumps associated with diseases such as Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia.

Cysteine Pathways Shape T Cell Expansion and Cancer Defense

A research team from the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health have discovered how the immune system's CD8+ T cells use the nutrient cysteine to control two essential functions that compete for this resource - the immune cell's ability to multiply and its ability to kill cancer cells.

Study Reveals How STING Protein Migrates to Trigger Immune Responses

UT Southwestern Medical Center researchers have identified how the quintessential immune protein known as stimulator of interferon genes (STING) migrates from one cellular organelle to another, a necessary step in its activation.

Synthetic Plasmid Design Enables Precise Control of DNA Replication

"If it ain't broke, don't fix it," goes the old adage, which Rice University professor James Chappell completely ignored in a recent Nature Communications publication.

Revive Penicillin’s Power by Exploiting Bacteria’s Hidden Weakness

When many disease-causing bacteria come into contact with penicillin, they do not necessarily die immediately, but instead enter a brief survival mode known as antibiotic tolerance.
