Gallic acid and stretching decrease osteoarthritis markers in cartilage cells
Researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination no.....»»
Study uncovers role of tissue viscoelasticity in cell response
To the casual eye, a memory foam mattress would appear to have no relationship to the behavior of cells and tissues. But an innovative study carried out at the Centro de Investigaciones Cardiovasculares (CNIC) in Madrid shows that viscoelasticity—t.....»»
Mechanical metamaterial enables long-distance component interaction for unique stretching properties
Metamaterials are artificial materials that do not occur in nature. Their components function like atoms in conventional materials but have special optical, electrical and magnetic properties. Interaction between the components is crucial to a metama.....»»
Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»

A causal theory for studying the cause-and-effect relationships of genes paves the way for targeted treatments
By studying changes in gene expression, researchers learn how cells function at a molecular level, which could help them understand the development of certain diseases......»»
Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid
With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, an.....»»
"The nastiest soils on Earth" are getting recognized as a bigger problem
Acid sulfate soils are characterized by their orange hue and their tendency to kill surrounding vegetation and fish. Anders Johnson's extensive research along Sweden's coastline reveals the widespread presence of these soils, underscoring their signi.....»»
Cells have more mini "organs" than once thought—these rogue organelles challenge biology"s fundamentals
Think back to that basic biology class you took in high school. You probably learned about organelles, those little "organs" inside cells that form compartments with individual functions. For example, mitochondria produce energy, lysosomes recycle wa.....»»
Beta cells: New insights into the structure, interactions and neuronal networking of primary cilia
Dysfunctions of the tiny cell processes (primary cilia) of the pancreatic beta cells could be a cause of type 2 diabetes. Little is known about the structure and function of these cilia. An international research team led by DZD researchers from the.....»»
New process enhances thermoplastic blends with polylactic acid
Bio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in the.....»»
