Using an international collection of nearly 900,000 samples, researchers have probed into the biology behind the fairly common loss of an X chromosome in white blood cells. Continue reading Researchers Take a Closer Look at the Sometimes Missing X Chromosome in White Blood Cells
Researchers find that mutations are not the only drivers of tumor formation and that epigenetic alterations could be involved too. Continue reading Why We Get Cancer: Mutations Might Not Be Always the Cause
Researchers have found a promising oral drug that could safely and reversibly reduce sperm mobility, shifting the burden of birth control more equally between sexes. Continue reading A New Male Contraceptive: Combating the Gender Imbalance in Reproductive Healthcare
by Sophia Renauldfigures by Salvador Balkus Our understanding of the genetic material, or DNA, that makes up organisms has exploded over the last several decades. We have discovered that DNA is made up of multiple genes, and that different genes have different functions. We have also found that there is inherent variability in genes, meaning that the DNA of one organism is not identical to … Continue reading Gene Editing to Treat Disease: A success story in sickle cell disease
Researchers have uncovered a genetic variant that is associated with childhood leukemia disparities in Hispanic-Americans. Continue reading Scientists discover genetic factor underlying childhood cancer risk in Hispanic-Americans
by Sanjana Kulkarnifigures by Swathy Karamchedu Forensic DNA testing has become crucial in criminal investigations and legal proceedings. DNA has linked people to crime scenes using hair or blood and exonerated wrongfully convicted individuals. This type of DNA is called environmental DNA (eDNA) because it is collected from the environment, rather than from a person. Scientists have also begun analyzing eDNA from non-human organisms. All … Continue reading DNA Detectives: How scientists are using DNA from the environment to see the unseen
Losing a tail on human’s evolutionary branch may have been caused by a rare kind of mutation resulting from parasitic, self-replicating DNA. Continue reading Researchers discover a unique mutation involved in how humans lost their tails
After generating 187 new genomes from primate species, researchers found a large fraction of the human genome that is highly conserved across evolution. Continue reading Researchers identify regions in the human genome that are consistent across primates
The Chimera of Greek myth had a lion’s head, goat’s body, and snake’s tail. Scientists have made a chimeric monkey with cells from two types of monkeys, which could one day lead to better lab models for scientists and donor organs for patients. Continue reading The birth of the first chimeric monkey that survived for 10 days
