Discovery of an atypical heat shock factor, HSF5, involved in meiotic mechanisms: Implications for male infertility      (via sciencedaily.com)     Original source 

Researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This discovery provides valuable insights into underlying causes of spermatogenic failure, the major contributor to male infertility. Furthermore, unlike other typical Heat Shock Factors, which primarily regulate gene expression in response to stress, such as heat shock, HSF5 plays a specific role in male germ production during meiosis under non-stress conditions.

New consensus statement aims to improve endometriosis evaluation      (via sciencedaily.com)     Original source 

A new expert consensus statement aims to improve endometriosis evaluation. Endometriosis is a common condition with substantial diagnostic delay, leading patients to experience pain, infertility, lost wages and interrupted relationships. The consensus provides recommendations for augmenting routine pelvic ultrasounds through additional maneuvers and imaging to improve diagnosis of deep endometriosis.

Everyday social interactions predict language development in infants      (via sciencedaily.com)     Original source 

Researchers found that when the adult talked and played socially with a 5-month-old baby, the baby's brain activity particularly increased in regions responsible for attention -- and the level of this type of activity predicted enhanced language development at later ages.

Even moderate alcohol usage during pregnancy linked to birth abnormalities      (via sciencedaily.com)     Original source 

Researchers have found that even low to moderate alcohol use by pregnant patients may contribute to subtle changes in their babies' prenatal development, including lower birth length and a shorter duration of gestation.

New discovery reveals how the egg controls sperm entry      (via sciencedaily.com)     Original source 

After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods.

First recognition of self in the mirror is spurred by touch      (via sciencedaily.com)     Original source 

Most babies begin recognizing themselves in mirrors when they are about a-year-and-a-half old. This kind of self-recognition is an important developmental milestone, and now scientists have discovered a key driver for it: experiences of touch.

Research sheds light on new strategy to treat infertility      (via sciencedaily.com)     Original source 

New research describes the science behind a promising technique to treat infertility by turning a skin cell into an egg that is capable of producing viable embryos. The technique could be used by women of advanced maternal age or for those who are unable to produce viable eggs due to previous treatment for cancer or other causes. It also raises the possibility of men in same-sex relationships having children who are genetically related to both parents.

How does a virus hijack insect sperm to control disease vectors and pests?      (via sciencedaily.com)     Original source 

A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus. A new study has uncovered how this microbial combination manipulates sperm, which could lead to refined techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.

Early vocabulary size is genetically linked to ADHD, literacy, and cognition      (via sciencedaily.com)     Original source 

Are genetic factors underlying children's language development linked to later-life outcomes? In a genome-wide analysis, an international research team found genetic associations between children's early vocabulary size and later-life ADHD, literacy, and general cognition. These associations changed dynamically across the first three years of life. Both producing more words in infancy and understanding fewer words in toddlerhood were associated with a higher risk of ADHD.

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.
