Making Age Reversal Real
November 4, 2023 1:23 pm Videos CommentsProfessor David Sinclair has some complaints about the human lifespan. It’s too short, for a start. But, “it doesn’t have to be this way,” he told an audience on Monday.
Researchers Reconstruct Early Stages of Embryo Development
November 4, 2023 12:36 pm Videos CommentsResearchers have managed to reconstruct the early stage of mammalian development using embryonic stem cells, showing that a critical mass of cells is needed for the cells to being self-organizing into the correct structure for an embryo to form.
Why Scratching Makes You Itch More
October 31, 2023 10:57 am Videos CommentsTurns out your mom was right: Scratching an itch only makes it worse. New research from scientists indicates that scratching causes the brain to release serotonin, which intensifies the itch sensation.
First Human Stomach Tissues Generated in Lab
October 30, 2023 12:24 pm Videos CommentsScientists used pluripotent stem cells to generate functional, three-dimensional human stomach tissue in a laboratory– creating a new tool for researching the development and diseases of an organ central to several public health crises.
The Skin Cancer Selfie
October 29, 2023 1:02 pm Videos CommentsIf melanoma, the deadliest form of skin cancer, is caught early enough it is almost always curable. Now, a camera capable of taking snapshots of the entire human body and rendering high-resolution images of a patient’s skin may help doctors spot cancer early and save lives.
Dietary Flavanols Reverse Age-related Memory Decline
October 27, 2023 2:26 pm Videos CommentsDietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a new study.
Researchers Observe Brain Development in Utero
October 27, 2023 2:03 pm Videos CommentsNew investigation methods using functional magnetic resonance tomography (fMRT) offer insights into fetal brain development. These in vivo observations will uncover different stages of the brain's development.
Protein Discovery May Unlock New HIV Treatment
October 24, 2024 10:16 am Videos CommentsLike a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists have now uncovered a new protein that participates in active HIV replication.
Scientists to Use Tiny Particles to Fight Big Diseases
October 23, 2024 12:49 pm Videos CommentsPhysicians will tell you: They are not winning the war on ovarian cancer. But researchers have combined medicine and advanced nanotechnological engineering to create a smarter, more targeted therapy that could overcome the most lethal gynecologic cancer.
Cancer Drug Resistance Has an ‘Off Switch’
October 21, 2024 11:29 am Videos CommentsScientists have uncovered details about how cancer is able to become drug resistant over time, a phenomenon that occurs because cancer cells within the same tumor aren’t identical.
Tarantula Venom Illuminates Electrical Activity in Live Cells
October 21, 2024 11:01 am Videos CommentsResearchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells.
Stem Cell-based Intestinal Tissue Implanted in Mice
October 20, 2024 10:21 am Videos CommentsResearchers have successfully transplanted “organoids” of functioning human intestinal tissue grown from pluripotent stem cells in a lab dish into mice– creating an unprecedented model for studying diseases of the intestine.
Babies’ Hearts May Beat Path to Heart Attack Treatments
October 17, 2024 11:50 am Videos CommentsThe seemingly miraculous power of babies’ hearts to repair themselves after being injured has spurred a research team to investigate if this ability can be harnessed for new heart attack treatments.
Brain’s Compass Relies on Geometric Relationships
October 16, 2024 2:24 pm Videos CommentsThe brain has a complex system for keeping track of which direction you are facing as you move about; remembering how to get from one place to another would otherwise be impossible. Researchers have now shown how the brain anchors this mental compass.
Scientists Sniff Out Unexpected Role for Stem Cells in the Brain
October 13, 2024 1:09 pm Videos CommentsScientists report that newly formed brain cells in the mouse olfactory system— the area that processes smells— play a critical role in maintaining proper connections.
