For decades, technical limitations and entrenched expectations shaped chromosome counts, illustrating how accepted scientific ideas can persist despite conflicting evidence.

VitroVivo Biotech LLC, a Maryland-based provider of histology and molecular histopathology products and laboratory services, is expanding access to specialized tissue-based research support through ...

In the first detailed chromosome map of the aardwolf, Texas A&M University researchers have discovered that, despite millions ...

For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of ...

The genus Calomys Waterhouse, 1837 is widely distributed within South America, being found in Venezuela, Colombia, Peru, Bolivia, Brazil, Paraguay, Uruguay and Argentina. Specimens of Calomys were ...

Scientists have taken an important step toward a gene therapy that could one day turn off the extra genetic material that causes Down syndrome (DS). Down syndrome is a genetic condition caused by an ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer — specifically, what happens when it vanishes.

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

The Y chromosome keeps grabbing attention in evolutionary science. People often wonder if it is stable, shrinking, or on its way to disappearing. This debate continues because it balances solid ...

A hallmark of cancerous cells is an abnormal number of chromosomes or chromosome arms, known as aneuploidy. While aneuploidy is detrimental to regular cells, it occurs in as many as 90% of tumors. How ...

Human egg cells are often prone to chromosomal errors. As women age, the error rate increases sharply — and can contribute to infertility, pregnancy loss, and ...
