Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.
Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells.
Paleontologists are gaining insight into life from over a billion years ago by analyzing chemical remnants in ancient rocks and studying the genetics of present-day animals.
Cheryl Rosenfeld has dedicated three decades to investigating the transmission of biological information from mothers to babies during pregnancy.
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology.
Recycling is just as essential in cells as in our more familiar macroscopic world. Cells continuously generate waste products and accumulate damaged components while performing regular functions.
Cyanobacteria are a key species in Earth's history, as they introduced atmospheric oxygen for the first time. The analysis of their evolution therefore provides important insights into the formation of modern aerobic ecosystems.
Can plant-derived nutrients alter gut bacteria to affect brain function? Scientists from the University of Leipzig Medical Center, the Max Planck Institute for Human Cognitive and Brain Sciences and the Helmholtz Centre for Environmental Research investigated this question in a study of overweight adults.
The effectiveness of any drug molecule depends on how well it interacts with the internal environment inside our body.
Going meatless is undoubtedly fashionable, as seen by Impossible Burger and “Meatless Mondays.”
Every system has a waste management system. The “peroxisomes” are cell organelles that dispose of toxic substances and lipids in the human body, among other things, and thereby avoid major diseases.
In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi's lab and collaborators at MIT have created a device that mimics this biological concept in order to detect disease.
The sequencing of the human genome promised a revolution in medicine, but scientists soon realized that a genetic blueprint alone does not show the body in action.
New research published in Nature Metabolism discovered the pathogenic mechanism driving mitochondrial enoyl reductase protein-associated neurodegeneration (MEPAN) syndrome, a rare pediatric neurodegenerative disease.
Michael Bloom, Associate Professor, Global and Community Health, received $158,900 from the National Institutes of Health for the project: "Impact of Exposure to Perfluoroalkyl Substances on Weight Loss: A Pilot Study of Hispanic Children with Overweight/Obesity Participating in a Community-based Weight Loss Intervention Program."
Imagine using insects as a source of chemicals to make plastics that can biodegrade later -; with the help of that very same type of bug.
By some estimates, the human nose can detect up to a trillion different smells with its hundreds of scent receptors.
Pioneering UK-based bio-tech business Clean Food Group is pleased to announce a new investment and strategic collaboration with Alianza Team, the Latin American food production and lipid-based technology expert, a leading company in the world of lipids, nutrition and frozen bakery.
Antiviral therapies are difficult to develop because viruses can rapidly mutate to become drug resistant.
Oxidative stress, caused by an imbalance of free radicals and antioxidants, regularly reduces the yield of pharmaceuticals and therapeutics produced via bioprocessing by about 10-15%. Now, Xheme, Inc.'s Xheme Multifunctional Additive (XMA), a programmable non-toxic nanoporous microparticle, has demonstrated the ability to significantly reduce or eliminate the damage of oxidative stress in bioprocessing conditions.
Many diseases can be successfully treated in the simple environment of a cell culture dish, but to successfully treat real people, the drug agent has to take a journey through the infinitely more complex environment within our bodies and arrive, intact, inside the affected cells.
