In your bloodstream, there are immune cells called neutrophils that, when faced with a pathogenic threat, will expel their DNA like a net to contain it. These DNA snares are called neutrophil extracellular traps or NETs. Researchers from Germany and the United States describe an important step in how these NETs are released and how they stop a fungus from establishing an infection in mice and human cells in the journal Developmental Cell.
Oocyte cryopreservation is on the rise, and whether a woman freezes her eggs before undergoing medical treatment that could leave her infertile or undergoes an elective procedure to avoid concerns about reproductive aging, extensive counseling should be the norm.
A new technique may force the centromere -- the mysterious stretch of DNA in the center of every chromosome -- to give up its secrets at last. The first test of the approach has yielded clues about the role of centromeres in Down syndrome, and further use may accelerate research on other conditions that may have roots in centromere-related problems.
Latest findings support the theory that teeth in the animal kingdom evolved from the jagged scales of ancient fish, the remnants of which can be seen today embedded in the skin of sharks and skate.
Young people today are taking part in a wider range of sexual practices, such as oral and anal sex, with opposite-sex partners compared to 20 years ago, according to new analysis by the London School of Hygiene & Tropical Medicine and UCL.
Using a simple 'mirror trick' and not-so-simple computational analysis, scientists affiliated with the Marine Biological Laboratory (MBL) have considerably improved the speed, efficiency, and resolution of a light-sheet microscope, with broad applications for enhanced imaging of live cells and embryos.
A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.
Prematurity is the main complication of pregnancy, and 15 million babies are born preterm worldwide each year. Physicians worldwide have investigated whether vaginal progesterone administration to women with a mid-trimester sonographic short cervix reduces the rate of preterm birth. Now physicians and researchers have found that when all available information is considered in an individual patient data meta-analysis, the results are clear: vaginal progesterone reduces the rate of preterm birth at <28, <30, <32, <34, <35, and <36 weeks.
California researchers have discovered that a medication used to prevent and treat malaria may also be effective for Zika virus. The drug, called chloroquine, has a long history of safe use during pregnancy, and is relatively inexpensive. The research was published today in Scientific Reports.
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have revealed the pathology of cells and structures stricken by optic nerve hypoplasia, a leading cause of childhood blindness in developed nations.
