Humans typically have 46 chromosomes arranged in 23 pairs. One of these pairs determines biological sex at the time of conception. Males usually have one X chromosome and one Y chromosome. The ...

System schematic for automatic detection of sister chromatid exchanges. Machine learning techniques have been used to develop a set of algorithms that can identify and count SCEs in microscopy images.

Genetic studies reveal a strange moment in human prehistory when male lineages nearly vanished, leaving only a small fraction to carry the Y-chromosome forward. Some researchers believe the Younger ...

Men with the most common form of lung cancer seem to be uniquely susceptible to losing the Y chromosome from their cells, which could have advantages and disadvantages. On the one hand, it shields ...

Here’s a quick reality check: ice cream sales go up in summer, and so do drownings. But no one thinks Ben & Jerry's is a silent killer. It’s correlation, not causation. Yet this same logical ...

Led by Arthur Blackburn, co-director of UVic's Advanced Microscopy Facility, the team developed a novel imaging technique that allowed them to achieve sub-Ångström resolution using a compact, ...

Losing the Y chromosome in immune cells in the blood is a common change in men that is often associated with aging – and certain cancers. TUCSON, Ariz. — University of Arizona Cancer Center ...

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...

The Y chromosome, the male relation genetic signature, has been a mystery to scientists for centuries. It’s the most repetitive and complex region of the human genome, and never before was it possible ...

As part of an expansion of the Eyring Science Center, BYU is installing two transmission electron microscopes. The new microscopes, also known as TEMs, are high-powered tools capable of capturing 3D ...

On July 30, World Athletics announced specifics on a new gene testing policy for athletes competing in the female category. To be eligible for the upcoming Tokyo World Athletics Championships, these ...

A new paper published in Nature on June 4 shines light on how an enigmatic part of male aging—the loss of Y chromosomes—is connected with a higher risk of dying from cancer. In an analysis of 4,127 ...
