Korean Researchers Identify New Mechanism Underlying Superbug Antibiotic Resistance

A joint research team led by Professor Hongbaek Cho of the Department of Biological Sciences at Sungkyunkwan University (SKKU) and Professor Jeong Min Chung of the Department of Biotechnology at The Catholic University of Korea has identified a new mechanism underlying antibiotic resistance in Pseudomonas aeruginosa, a major multidrug-resistant "superbug."

Cryo-EM Snapshots Capture Multi-Stage Structural Transitions During DNA Recombination

Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject their DNA, and then use the host's genetic machinery to reproduce. In doing so, they may have evolved some of the most efficient gene editing tools ever seen in nature.

Researchers Capture Real-Time Molecular Movie of Penicillin Enzymatic Ring Closure

Researchers from the University of Oxford and international collaborators have revealed previously unseen rapid chemical stages in the formation of β-lactam antibiotics like penicillin, offering insights that can support future antibiotic development.

Single-Cell RNA Sequencing Maps Neuroblastoma Intratumoral Heterogeneity

Neuroblastoma is the most common solid tumor found outside of the brain in children, yet why some children respond well to treatment while others do not has remained poorly understood. St. Jude Children's Research Hospital scientists and their collaborators built one of the most comprehensive datasets of neuroblastoma cells to date, using it to define the tumor's cell types and identify a gene signature marking a malignant cell population tied to poor prognosis.

Higher-Order Receptor Clustering Acts as Hidden Lymphangiogenic Signal Amplifier

Lymphatic vessels act as the body's "drainage system," collecting excess fluid from tissues. When lymphatic drainage is impaired because lymphatic vessels are underdeveloped, damaged, or dysfunctional, lymphedema can develop, causing swelling, particularly in the arms and legs.

Targeting Host Cellular Repair Mechanisms Enhances Tissue Resistance to Infection

Epithelial cells form the body's frontline barriers, helping keep microbes, toxins, and other harmful substances out. Yet these protective cells are constantly exposed to threats, including microbial infections.

Study Redefines Structural Framework of Primate Cone Photoreceptor Outer Segments

For over 60 years, scientists have debated a basic structural question about cone photoreceptors, the cells that let vertebrates see color: are their light-sensing disk membranes closed off inside the cell, or are they open to the extracellular space?

New Insights Into How Giant-Nucleus Cells Promote Early-Stage Cancer Growth

Iron is an essential micronutrient, but excess iron can damage cells and increase cancer risk. While many cells die from iron-induced oxidative stress, a subset survives and may become cancerous. Previously, the identity of these surviving cells was unclear.

Unexpected Mechanism Shows Muscle Cells Limit Rather Than Drive Membrane Growth

Every movement we make, from blinking to sprinting, depends on the ability of muscle fibers to contract in a rapid and coordinated way. Achieving this precision requires an intricate internal membrane network known as the transverse tubule, or T-tubule, system.

Researchers Unlock Key Potassium Channel That Controls Plant Stalk Elongation

Potassium (K) is one of the three essential nutrients for plants. It plays a critical role in a wide range of processes, including cell growth, photosynthesis, and regulation of water balance. Plants take up K from the soil and circulate it throughout their bodies via molecules called K+ channels.
