Proteomic analysis of oocytes from obese mice showed changes in a protein that promotes antioxidant production and may alter meiotic spindles.
Certain female mosquitoes quickly evolve more selective mating behavior when faced with existential threats from other invasive mosquito species, with concurrent changes to certain genetic regions, according to new research from North Carolina State University.
In a study published in Behavioral Ecology researchers from Uppsala University show that the same type of sperm is not always the best for all male birds. Depending on how attractive or dominant you are you might be more successful with longer or shorter sperm.
What can scientists learn about human neurodegenerative disease from a major soybean pest? It's not a trick question; the answer lies in the soybean cyst nematode, one of two classes of microscopic roundworms known to lose and then regain mobility as part of their life cycle. A new study from the University of Illinois explains how it works.
New work from Carnegie's Ethan Greenblatt and Allan Spradling reveals that the genetic factors underlying fragile X syndrome, and potentially from other autism-related disorders, stem from defects in the cell's ability to create unusually large protein structures. They found that mutations in the gene Fmr1 create problems in the and the reproductive system. They can lead to the most-common form of inherited autism, fragile X syndrome, as well as to premature ovarian failure.
A new point-of-care test for the parasite Toxoplasma gondii can be performed with a drop of the mother's blood. The test meets the WHO's criteria. It is sensitive, specific, quick, easy to perform, and inexpensive.
A study led by Indiana University suggests that computer models used to predict the spread of epidemics from climate change -- such as crop blights or disease outbreaks -- may not take into account an important factor in predicting their severity.
Research from the University of Pennsylvania School of Nursing and the Children's Hospital of Philadelphia found that, among the 151 largest cities in the United States, only Philadelphia and New York City have local legislation that protects a nursing mother who returns to work outside the home and who wants to continue breastfeeding.
Researchers have discovered that the hearts of newborn piglets have one remarkable ability. They can almost completely heal themselves after experimental heart attacks. This regenerative capacity is short-lived -- disappearing by day three after birth, and this is the first time the ability regrow heart muscle has been shown in large mammals, the researchers report in the journal Circulation. This research has impactful clinical implications, says UAB researcher Jianyi 'Jay' Zhang, M.D., Ph.D.
Immune cells usually ignored by neuroscientists appear to play an important role in determining whether an animal's sexual behavior will be more typical of a male or female.
