Somatic gene mutations in brain cells could contribute to schizophrenia pathology

Schizophrenia is a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. Researchers have long searched for genetic influences in the disease, but genetic mutations have been identified in only a small fraction--fewer than a quarter--of sequenced patients.

Study reveals physical phenomena relied by oocytes to grow big

Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells.

Study suggests revisiting 14-day limit on human embryo in a dish

An international team of bioethicists and scientists, led by a researcher at Case Western Reserve University, contends it may be justified to go beyond the standing 14-day limit that restricts how long researchers can study human embryos in a dish.

Researchers discover a safe, effective, reversible male contraceptive agent

In a new paper published by Nature Communications, The Lundquist Institute (TLI) Investigator Wei Yan, MD, PhD, and his research colleagues spell out an innovative strategy that has led to the discovery of a natural compound as a safe, effective and reversible male contraceptive agent in pre-clinical animal models

Study outlines the reasons to test pediatric cancer patients for inherited genes

Because cancers in children are rare, many details about their biology remain unknown. In the field of cancer genetics, there's a limited understanding of how inherited genetic changes may contribute to the formation and growth of tumors.

Male fruit flies win genetic race with rivals in post-mating fertilization game

Scientists have accepted natural selection as a driver of evolution for more than 160 years, thanks to Charles Darwin

Researchers explore the origin of the body axis in animals

Egg cells start out as round blobs. After fertilization, they begin transforming into people, dogs, fish, or other animals by orienting head to tail, back to belly, and left to right.

Researchers produce first African lion in-vitro embryos after vitrification of immature oocytes

A team of scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) inGermany, Givskud Zoo - Zootopia in Denmark and the University of Milan in Italy succeeded in producing the very first African lionin-vitroembryos after the vitrification of immature oocytes.

Researchers explain the role of enzyme that facilitates appropriate development of mouse embryo

The body plan of an organism, crafted over millennia of evolutionary trial and error, is so exquisitely fine-tuned that even a subtle deviation can be detrimental to individual survival and reproductive success.

Intermediate embryonic stem cell type could lead to advances in regenerative medicine

A team led by UT Southwestern has derived a new "intermediate" embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture dish.

Coming abortion fight could threaten birth control, too

Abortion opponents were among those most excited by the addition of Justice Amy Coney Barrett to the Supreme Court. And they had good reason to be.

Oregon biologists reveal molecular mechanisms that produce DNA damage in sperm

University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat.

Doctors propose ways to reduce obstetrical complications in women with endometriosis

A team of doctors from RUDN University with their Italian colleagues had studied the data of existing studies on the effect of endometriosis on pregnancy and childbirth and suggested ways to reduce obstetrical complications in women with this condition.

Sperm mitochondrial DNA biomarkers may predict male reproductive health and pregnancy success

Researchers at the University of Massachusetts Amherst have identified a single-measure biomarker in sperm mitochondrial DNA that may predict male reproductive health and pregnancy success.

Vitamin D deficiency during early development can influence metabolic health

Using a zebrafish model, researchers from North Carolina State University have found that vitamin D deficiency during early development can disrupt the metabolic balance between growth and fat accumulation.

Women treated with fertility-sparing surgery for ovarian tumors could become pregnant

Women receiving fertility-sparing surgery for treatment of borderline ovarian tumors were able to have children, a study from Karolinska Institutet in Sweden published in Fertility & Sterility shows.

Study finds spectrum of genes responsible for inherited hearing loss in Israeli Jewish families

Until now, seven genes were known to be involved in hearing loss in Israel's Jewish population. A new study led by Zippora Brownstein, PhD, and Prof. Karen Avraham from the Sackler Faculty of Medicine at Tel Aviv University has found that 32 genes are responsible for inherited hearing loss in Israeli Jewish families.

Fertility treatment suspensions during COVID-19 has a negative impact on mental health

The suspension of fertility treatments due to the COVID-19 pandemic has had a variety of psychological impacts on women whose treatments were cancelled, but there are several protective factors that can be fostered to help in the future, according to a new study by Jennifer Gordon and Ashley Balsom of University of Regina, Canada, published 18 September in the open-access journal PLOS ONE.

Researchers develop AI system to help better select embryos for implantation

For many people who are struggling to conceive, in-vitro fertilization (IVF) can offer a life-changing solution. But the average success rate for IVF is only about 30 percent.
