Unveiling the Evolutionary Origins of Bilaterian Species

700 million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today's standards, the animal had a front and a back, a top and a bottom.

Nutrient Deprivation Induces Embryonic Diapause in Hungry Mouse Mums

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental stress and then re-enter development when conditions improve.

Cellular Atlas of the Human Ovary Offers Hope for Restoring Hormone Production and Fertility

A new "atlas" of the human ovary provides insights that could lead to treatments restoring ovarian hormone production and the ability to have biologically related children, according to University of Michigan engineers.

New Study Unveils Mechanism Behind Mice Ovary Development

Scientists at the Francis Crick Institute have provided insight into the proteins governing the development of mice's ovaries both prenatally and postnatally. This might help comprehend the progression of female infertility.

How Does the Egg Coat Prevent Multiple Fertilization

The surrounding egg coat tightens once a sperm fertilizes an egg, mechanically blocking further sperm from entering and causing the embryo to die.

Researchers Isolate Adaptable Leptospirosis Strain in Austrian Cattle

Leptospirosis is a globally distributed infectious disease that affects both animals and humans. While the infection is endemic in tropical regions, its incidence seems to increase in temperate regions.

No Consistent Evidence for Sperm Quality Decreasing With Age

Scientists have shown that while male fertility and sperm fitness decrease with age in humans, this tendency does not hold true for other animals. The journal Nature Communications has published the findings.

Zipping Up Chromosomes: The Synaptonemal Complex Revealed

We have two copies of each chromosome in every cell in our bodies except in our reproductive cells. Sperm and egg cells contain a single copy of each chromosome with a unique mix of genes from our parents, an evolutionary trick to give our offspring genetic variability.
