Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Scientists discovered that a genome editing tool can precisely and efficiently alter human stem cells.
Vanderbilt University researcher William Mitchell, M.D., Ph.D., and colleagues in Germany and Canada have demonstrated a method for detecting “cell-free” tumor DNA in the bloodstream.
The idea that breast cancer becomes more prevalent with age is fairly well established, but the reasons why are still uncertain. Now, scientists from the Lawrence Berkeley National Laboratory have new insights into why older women are more susceptible to breast cancer.
A study has linked aging at the cellular level to overall human aging through a molecular interaction involving two proteins and chromosome ends called telomeres.
These findings could shed light on related Alzheimer's protein.
Swiss scientists have used a cutting-edge method to stimulate neurons with light. They have successfully recorded synaptic transmission between neurons in a live animal for the first time.
Scientists have created primordial germ cells – cells that will go on to become egg and sperm – using human embryonic stem cells.
Researchers discovered what keeps an enzyme from becoming overzealous in its clipping of DNA.
A team of researchers has made big strides toward a future in which the predominant chemical factories of the world are colonies of genetically engineered bacteria.
One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bacteria is still a puzzle to scientists.
Scientists have color marked individual brain cells to help improve our understanding of how the brain works.
Scientists at A*STAR's Institute of Medical Biology (IMB) and Institute of Molecular and Cellular Biology (IMCB) have identified a genetic pathway that accounts for the extraordinary size of the human brain.
A recent exploratory study asked genetics experts to consider genome sequencing for newborn populations, revealing varying opinions about the future of genomics.
A new Yale-led study of children with neurodevelopmental abnormalities of the brain identifies a “cutting” enzyme crucial to the shaping and division of brain cells as well as the replenishment of neural stem cells.
Neuroscientists have proposed that brain cells come in different subtypes that have different properties and responsibilities.
Scientists have found a new way to help Type 1 diabetes patients defend themselves against life-threatening low blood sugar.
Chemical modifications to DNA’s packaging — known as epigenetic changes — can activate or repress genes involved in autism spectrum disorders (ASDs) and early brain development.
New research has identified a fundamental mechanism for controlling protein function.
Scientists have developed a powerful new system for studying how proteins and other biological molecules form and lose their natural folded structures.
Investigators have developed a method for detecting unwanted DNA breaks—across the entire genome of human cells—induced by the popular gene-editing tools called CRISPR-Cas RNA-guided nucleases (RGNs).
Researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes.
New rules proposed in Britain would make it the first country to allow embryos to be made from the DNA of three people in order to prevent mothers from passing on potentially fatal genetic diseases to their babies.
Ancient DNA extracted from the bones and teeth of giant lemurs that lived thousands of years ago in Madagascar may help explain why the giant lemurs went extinct. It also explains what factors make some surviving species more at risk today, says a study in the Journal of Human Evolution.
