Published Oocytes outsmart toxic proteins to preserve long-term female fertility (via sciencedaily.com) Original source
The accumulation of misfolded or damaged proteins in long-lived, non-dividing cells like neurons are linked to neurodegenerative diseases like Alzheimer's. A study now finds that the build-up of these toxic proteins also influences oocyte quality and female fertility. The researchers discovered that mouse oocytes have specialized structures which roam the cytoplasm and act like a clean-up crew which capture and hold onto protein aggregates, rendering them harmless. Failure to degrade the toxic proteins led to the formation of defective eggs. 3 in 5 (60%) of mouse embryos that inherited the toxic proteins failed to complete the very earlies stages of development. The study presents a new frontier to explore the underlying mechanisms of poor oocyte quality, which is the leading cause of female infertility.
Published Scientists discover new target for reversible, non-hormonal male birth control (via sciencedaily.com) Original source
Scientists discovered a new target for reversible, non-hormonal male birth control. The drug, an HDAC inhibitor, blocked sperm production and fertility in male mice without affecting libido or future reproduction.
Published Stress during pregnancy can lead to early maturation of first-born daughters (via sciencedaily.com) Original source
Researchers have found a correlation between early signs of adrenal puberty in first-born daughters and their mothers' having experienced high levels of prenatal stress. They did not find the same result in boys or daughters who were not first-born.
Published To boost a preschooler's language skills, consider reminiscing (via sciencedaily.com) Original source
Book sharing is a popular way parents engage young children in conversation. However, not all parents are comfortable with book sharing and not all children like having books read to them. Research provides an alternative. To boost the quality of a preschooler's language experience and skills, consider reminiscing with them. Findings show reminiscing is very good at eliciting high quality speech from parents, and in many ways, is just as good as book sharing (wordless picture books).
Published What can bulls tell us about men? (via sciencedaily.com) Original source
Researchers have found genes in the reproductive organs of bulls that influence fertility. The findings can be transferred to humans, as these genes are also present in men.
Published How parents can help prevent the development of ADHD symptoms (via sciencedaily.com) Original source
Parents of young children with an excitable or exuberant temperament could adapt their parenting style to help moderate their child's potential development of Attention Deficit/Hyperactivity Disorder (ADHD), according to a new study.
Published Male fertility gene discovery reveals path to success for sperm (via sciencedaily.com) Original source
The discovery of a pair of genes that work in perfect harmony to protect male fertility could provide new insights into some unexplained cases of the most severe form of infertility, research suggests.
Published Genetic cause of low birth weight among children conceived after fertility treatment (via sciencedaily.com) Original source
A medical researcher has identified a genetic cause for the increased risk of low birth weight in babies born following assisted reproductive technologies such as IVF.
Published Patterns of brain connectivity differ between pre-term and term babies (via sciencedaily.com) Original source
A new scanning study of 390 babies has shown distinct patterns between term and pre-term babies in the moment-to-moment activity and connectivity of brain networks.
Published Early drawing and building skills linked to enhanced education and behavior in children (via sciencedaily.com) Original source
Fine motor skills in young children are linked to better GCSE scores and fewer behavioral problems in childhood and adolescence, according to a new study.
Published How ovarian tissue freezing could prevent menopause -- possibly forever (via sciencedaily.com) Original source
A new paradigm around the biological processes of menopause is capturing the attention of scientists. The primary question: can menopause be delayed in healthy women, allowing them to extend their child-bearing years -- and perhaps even forestall some of the health risks and uncomfortable symptoms linked to plummeting estrogen levels?
Published Study suggests secret for getting teens to listen to unsolicited advice (via sciencedaily.com) Original source
A new study may hold a secret for getting your teenager to listen to appreciate your unsolicited advice. The study, which included 'emerging adults' -- those in their late teens and early 20s -- found teens will appreciate parents' unsolicited advice, but only if the parent is supportive of their teens' autonomy.
Published Gene expression atlas captures where ovulation can go awry (via sciencedaily.com) Original source
An interdisciplinary collaboration used a cutting-edge form of RNA tagging to map the gene expression that occurs during follicle maturation and ovulation in mice.
Published Navigating the 'big little leap' to kindergarten (via sciencedaily.com) Original source
No matter how well children are prepared for kindergarten, their transition to the classroom during the first few months plays a key role in their success, a new study suggests.
Published Semen microbiome health may impact male fertility (via sciencedaily.com) Original source
A new study finds that a small group of microorganisms may be influencing sperm motility.
Published Relationships with caring adults provide a buffer against depression, anxiety, regardless of adverse childhood experiences (via sciencedaily.com) Original source
A new study sought to identify factors that would bolster resilience for marginalized and minoritized youth, using data from the Boricua Youth Study, a longitudinal study following three generations of families over 20 years in both Puerto Rico and the South Bronx, New York.
Published Surprise discovery: For most animals, sperm quality does not reduce with age (via sciencedaily.com) Original source
In humans, male fertility and sperm fitness decline with age, but scientists have made the surprising discovery that this pattern is not consistent in other animals. The team assessed the results of 379 studies which covered a wide range of animals, including mammals, insects, birds, and fish.
Published Aging mouse sperm affects MicroRNA, increasing the risk of neurodevelopmental disorders (via sciencedaily.com) Original source
Much is known about the added complication to pregnancy when it comes to the age of the mother, but recent studies show that the age of the father can also heighten the risk of neurodevelopmental disorders. A team of researchers has explored the impacts of paternal aging on microRNAs, the molecules that play a crucial role in regulating gene expression.
Published More siblings mean poorer mental health for teens (via sciencedaily.com) Original source
Teens from larger families have poorer mental health than those with fewer siblings, according to a large analysis of children in the United States and China. The details of the pattern vary depending on factors such as the spacing of sibling ages and the age of the siblings. But the fact that the overall pattern was found in both countries is striking.
Published Putting your toddler in front of the TV? You might hurt their ability to process the world around them, new data suggests (via sciencedaily.com) Original source
Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviors, such as being disengaged and disinterested in activities, seeking more intense stimulation in an environment, or being overwhelmed by sensations like loud sounds or bright lights, according to recent data.
