Ingenious Ocean Microbes Team Up Brilliantly To Gather Food When It’s Scarce
What’s a hungry marine microbe to do when the pickings are slim? It must capture nutrients – nitrogen, phosphorus, or iron – to survive, yet…
Early Antiviral Response in the Nose May Determine Mild / Severe Course of COVID-19
Cells taken from patients at the time of diagnosis who later developed severe COVID-19 show a muted antiviral response, study finds. Researchers studied cells collected…
Neurotransmitter Levels in the Brain Predict Math Ability
Glutamate and GABA in the brain have reverse relationships with math ability, which switch during development. The neurotransmitters GABA and glutamate have complementary roles —…
Biomolecular Bonsai: Controlling the Pruning and Strengthening of Neuron Branches in the Brain
Researchers identify molecular cues that make developing neurons remodel their connections. At this very moment, the billions of neurons in your brain are using their…
Scientists Have Created the First Genetically Engineered Marsupial
Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) have succeeded in creating the first genetically engineered marsupial. This study, published in the scientific…
New Research Reveals Immune Cell’s Response to Pathogens Differs Greatly by Sex and Age
A new University of Southern California (USC) study of a common, yet poorly understood type of white blood cell reveals the immune cell’s response to…
How the Visual System Shows Us a More Persistent World
An international collaboration elucidates the mechanisms that facilitate accurate identification of moving images. Imagine meeting a friend on the street, and imagine that with every…
3D “Assembloid” Shows How the COVID-19 Virus Infects Brain Cells
Researchers at University of California San Diego School of Medicine and Rady Children’s Institute for Genomic Medicine have produced a stem cell model that demonstrates…
Vital Protective Mechanism Discovered: Dying Cells Protect Their Neighbors To Maintain Tissue Integrity
Cells undergoing cell death protect their neighbors to maintain tissue integrity. To enable tissue renewal, human tissues constantly eliminate millions of cells, without jeopardizing tissue…
Parkinson’s, Cancer, and Type 2 Diabetes Share a Key Element That Drives Disease
Enzyme with central role in cancer and type 2 diabetes also activates “clean-up” protein in Parkinson’s. When cells are stressed, chemical alarms go off, setting…
Researchers Create New CRISPR Genetic Tools to Help Contain Mosquito Disease Transmission
Genetics toolkit targets less researched Culex mosquitoes, which transmit West Nile virus and avian malaria. Since the onset of the CRISPR genetic editing revolution, scientists…
“Primed” for Infection: Cells Damaged by Chronic Lung Disease Can Result in Severe COVID
Results from a TGen-led international study suggest that SARS-CoV-2 takes advantage of genetic changes among patients with pre-existing lung diseases. The results of a study…
How Information Beyond the Genetic Sequence Is Encoded in Plant Sperm and Passed Down the Generations
Hereditary information is passed from parent to offspring in the genetic code, DNA, and epigenetically through chemically induced modifications around the DNA. New research from…
Using Biodegradable Nanoparticles to Shut Down the Power Stations of Cancer Cells
New biodegradable nanoparticles for photodynamic therapy that enter cancer cells and ‘shut down’ their mitochondria power stations co-designed by TU/e researchers. An emerging nanomedicine cancer…
Visualizing Metabolic Processes at the Single-Cell Level – Using Genetically Encoded Biosensor Paired With AI
Understanding cellular metabolism – how a cell uses energy – could be key to treating a wide array of diseases, including vascular diseases and cancer….
Potential Treatment May Prevent Cancer Cells From Hijacking Metabolic Pathways
Metabolic Enzyme Promotes Neuroblastoma Aggressiveness High-risk neuroblastoma is an aggressive childhood cancer with poor treatment outcomes. Despite intensive chemotherapy and radiotherapy, less than 50 percent…
Cancer Cells Eat Themselves to Survive Life-Threatening Damage
It is the membrane of cancer cells that is at the focus of the new research now showing a completely new way in which cancer…
