Climate Change Could Lead to a Dramatic Temperature-Linked Decrease in Essential Omega-3 Fatty Acids, According to New Study
The effects of global climate change already are resulting in the loss of sea ice, accelerated sea level rise, and longer and more intense heat waves, among other threats. Now, the first-ever survey of planktonic lipids in the global ocean predicts a temperature-linked decrease in the production of essential omega-3 fatty acids, an important subset of lipid molecules.
IAFNS Announces Two New Summer Fellows to Study Lipids, Recycled Resins
Now in its second year, IAFNS Summer Research Opportunity Fellowship Program supports the next generation of scientists.
Moffitt Researchers Identify Pathway that Regulates Lipid Synthesis and Contributes to Tumor Survival
In a new study published in the journal Cell Reports, Moffitt Cancer Center researchers show that cancer cells in an acidic environment undergo lipid synthesis and accumulation. The team identified the key signaling molecules responsible for these changes and discovered that these alterations are associated with poor outcomes and disease progression among breast cancer patients.
Sweet! How Glycogen is Linked to Heat Generation in Fat Cells
University of California San Diego researchers, with international colleagues, describe how energy expenditure and heat production are regulated in obesity through a previously unknown cellular pathway.
Study Sheds Light on Mechanism of Liposome Accumulation in Tumors
Dmitri Simberg, PhD, associate professor in the University of Colorado Skaggs School of Pharmacy, released a new study of the effectiveness of different types of fluorescent labels used to monitor the accumulation of liposomes in tumors. The study was published on July 1, 2021, in ACS Nano.
Molecular Connections from Plants to Fungi to Ants
Leaf-cutter ants tend fungal gardens that convert lipids in leaves into lipids the ants can use for energy, building cells, and communication between organisms. New research has found that different regions of the ants’ fungal gardens were enriched with different lipids. This helps scientists understand communications between organisms in different kingdoms of life.
Shining, Colored LED Lighting on Microalgae for Next-Generation Biofuel
As biofuels continue to present challenges, microalgae are gaining momentum as a biofuel energy crop. In the Journal of Renewable and Sustainable Energy, researchers show how a combination of monochromatic red and blue LED illumination on one type of microalga can enhance its growth and increase the biosynthesis of critical components, such as lipids, for microalgae feedstock development. The researchers focused on Dunaliella salina, typically extracted from sea salt fields and found in salt lakes.
Skin-immersion study shows serious damage after 12 hours in water
A new study from researchers at Binghamton University, State University of New York could change the way that medical professionals and scientists think about the long-term effects of skin immersion in water.
Dietary fats interact with grape tannins to influence wine taste
Researchers reporting in ACS’ Journal of Agricultural and Food Chemistry have explored how lipids –– fatty molecules abundant in cheese, meats, vegetable oils and other foods –– interact with grape tannins, masking the undesirable flavors of the wine compounds.
Making Heads or Tails Out of Phospholipid Synthesis
A team of researchers from UC San Diego, UCLA and the University of South Carolina has demonstrated how membrane-formation takes place in water from natural alkaline sources like soda lakes and hydrothermal oceanic vents.
Ambitious Project to Understand Cellular Evolution Underway
Project focuses on lipids (fat molecules) as the starting point to understand the evolution of eukaryotic cells, carrying implications for human health and disease.
Fat-Based Molecules are Key to Zika Virus Infection
Researchers from PNNL have helped colleagues at OHSU identify lipid molecules required for Zika infection in human cells. The specific lipids involved could also be a clue to why the virus primarily infects brain tissue.
Scientists Team Up to Create Spongy Droplets that Mimic Cellular Organelles
Taking a bottom-up approach to synthetic biology, UC San Diego chemists and physicists show that lipid sponge droplets can be programmed to internally concentrate specific proteins, host and accelerate biochemical transformations and control enzymatic reactions.
Biomedical researchers get closer to why eczema happens
A new study from Binghamton University, State University of New York may help to peel back the layers of unhealthy skin — at least metaphorically speaking — and get closer to a cure.
PECASE Honoree James Olzmann Investigates the Secrets of Lipid Droplets
Lipid droplets, membrane-bound packages of lipids, have been one of our cells’ least studied components. But recently, more scientists have begun probing the mysteries that surround them and finding fascinating results. James Olzmann, Ph.D., discusses how a protein on the surface of lipid droplets could be targeted to help treat cancer.
Scientists Discover New Clue Behind Age-Related Diseases and Food Spoilage
Berkeley Lab scientists have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time.
Lipid signaling from beta cells can potentiate an inflammatory macrophage polarization
The insulin-producing beta cells in the pancreas unwittingly produce a signal that may aid their own demise in Type 1 diabetes, according to a study of the lipid signals that drive macrophage cells in the body to two different phenotypes of activated immune cells.
Researchers Show How Ebola Virus Hijacks Host Lipids
Robert Stahelin studies some of the world’s deadliest viruses. Filoviruses, including Ebola virus and Marburg virus, cause viral hemorrhagic fever with high fatality rates. Stahelin, professor at Purdue University, examines how these viruses take advantage of human host cells.
