Researchers 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.
Turns 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.
Scientists 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.
If 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 cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a new study.
New 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.
Like 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.
Physicians 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.
Scientists 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.
Researchers 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.
Researchers 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.
The 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.
The 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 report that newly formed brain cells in the mouse olfactory system— the area that processes smells— play a critical role in maintaining proper connections.
Scientists have discovered a new class of molecules– produced in human and mouse fat– that protects against diabetes. The researchers found that giving this new fat to mice with the equivalent of type 2 diabetes lowered their elevated blood sugar.
