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.

Cells Use Protein Partnership to Manage Oxidative Stress

Cornell researchers have discovered a new way cells regulate how they respond to stress, identifying an interaction between two proteins that helps keep a critical cellular recycling system in balance.

Cryo-EM Uncovers Alarmone-Driven RNA Transcription Initiation

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) into ribonucleic acid (RNA) can be initiated.

Natural Molecular Brake Prevents Uncontrolled DNA Replication in Cells

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we would die.

Novel Epigenetic Regulator Enhances Downy Mildew Resistance in Brassica rapa

Downy mildew is a major constraint on Brassica crop production worldwide, especially during early developmental stages when plants are highly vulnerable to infection.

MYC Gene's Dual Role in Cancer Growth and Immune Suppression

The cancer gene MYC camouflages tumors by suppressing alarm signals that normally activate the immune system.

Protein Translation Enzyme Governs Macrophage Maturation and Tissue Homeostasis

A new study led by researchers at the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health found that an enzyme involved in protein translation is essential for circulating immune cells, called monocytes, to mature into tissue-resident macrophages, a specialized population of immune cells that maintain organ health by clearing dead cells and debris.

Bioinformatic Framework Reconstructs Evolutionary History of Complex Polyploid Genomes

Whole-genome duplication has repeatedly reshaped plant genomes and driven evolutionary innovation, ecological adaptation, and crop diversification.

Unveiling How a Respiratory Bacterium Obtains Lipids and Targets Fatty Tissues

A multidisciplinary team has uncovered a key mechanism that allows the human bacterium Mycoplasma pneumoniae-responsible for atypical pneumonia and other respiratory infections-to obtain cholesterol and other essential lipids directly from the human body.

Ancient WUS Genes and Expression Thresholds Shape Shoot Regeneration

Unlike animals, plants generate most organs after embryogenesis through stem cell–driven meristems, enabling lifelong growth and regeneration.

High-Tech Imaging Unlocks Genetic Secrets Of Nutrient-Rich Seeds

By rapidly analyzing nearly 12,000 individual seeds, the approach uncovers genetic loci that simultaneously influence seed morphology and mineral composition, opening new avenues for crop biofortification and safer food production.

Identifying Molecules That Activate and Inhibit Key Protein Function

Researchers at Northwestern University have discovered a concealed molecular "control switch" within a protein that plays a crucial role in the body's ability to perceive taste, regulate blood sugar, and protect the gut.

Dual Genetic Mutations Drive RNA Mis-Splicing and Leukemia Progression

Treating acute myeloid leukemia (AML) depends on knowing what goes wrong inside cells. A new study suggests that two genetic mutations – IDH2 and SRSF2 – work cooperatively to mis-splice RNA messages and change how blood cells develop.

Blocking Retinoic Acid Pathway Improves Dendritic Cell Anti-Tumor Function

Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.
