Follow-up imaging for women with non-metastatic breast cancer varies widely across the country, according to a new study led by researchers at UC San Francisco. Some patients go without the annual mammograms that experts recommend, while others with the same cancer diagnosis receive full-body scans that expose them to significant amounts of radiation and are not recommended by experts.
Genetic research at has shed new light on how isolated populations of the same species evolve toward reproductive incompatibility and thus become separate species.
The sex of a baby controls the level of small molecules known as metabolites in the pregnant mother's blood, which may explain why risks of some diseases in pregnancy vary depending whether the mother is carrying a boy or a girl, according to new research from the University of Cambridge.
It was long thought that during an embryo's first cell division, one spindle is responsible for segregating the embryo's chromosomes into two cells. EMBL scientists now show that there are actually two spindles, one for each set of parental chromosomes, meaning that the genetic information from each parent is kept apart throughout the first division. Science publishes the results -- bound to change biology textbooks -- on July 12, 2018.
A new method allows researchers to systematically identify specialized proteins called 'nuclesome displacing factors' that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions.
In a new study publishing July 12 in the open-access journal PLOS Biology, Vanessa Hill, Mimi Shirasu-Hiza and colleagues at Columbia University, New York, found that short-sleeping fruit fly mutants shared the common defect of sensitivity to acute oxidative stress, and thus that sleep supports antioxidant processes.
Researchers at Osaka University used live imaging of the Drosophila embryonic hindgut and computer simulations to clarify that a novel cellular behavior called 'cell sliding' was important for the LR asymmetric morphogenesis of the organ.
A new mixture of cryoprotectives allows for an unprecedented high motility of frozen rhinoceros sperm after thawing, report scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Berlin, Germany. These new cryoprotectives can increase the prospects of utilizing assisted reproduction techniques for many endangered wildlife species. The study, based on three rhinoceros species, has now been published in the journal PLOS ONE.
A wide range of fetal genetic abnormalities could soon be detected in early pregnancy thanks to a world-first study led by University of South Australia researchers using lab-on-a-chip, noninvasive technology.
A study finds that chemicals used in flame retardants, plasticizers and other commercial products are broken down through the process of metabolism into other compounds. Researchers say not enough is known about the dangers posed by those compounds, known as metabolites.
