"Genetic Research Unveils Surprising Connections Between Humans and Animals"

Researchers analyzed the DNA sequences from 240 mammalian species, showing how comparative genomics can shed light on how certain species achieve extraordinary feats and help scientists better understand the functional parts of the human genome. They pinpointed the genetic basis for uncommon mammalian traits, such as the ability to hibernate or detect faint scents from miles away. They also found genetic variants that are more likely to play causal roles in rare and common human diseases. The findings come from analyses of DNA samples collected by more than 50 different institutions worldwide, including many from the San Diego Wildlife Alliance, which provided many genomes from species that are threatened or endangered.

"240 Mammal Genomes Unravel Secrets of Human DNA"

The Zoonomia Project has compared DNA sequences from 240 mammalian species to identify key parts of the human genome that have remained unchanged for millions of years, shedding light on disease susceptibility and unique mammalian traits. The findings offer potential for improved disease understanding and biodiversity conservation. The researchers identified regions of the genomes that are most conserved across mammalian species and millions of years of evolution, pinpointed species that may be particularly susceptible to extinction, and identified genetic variants that are more likely to play causal roles in rare and common human diseases.

Gene discovery brings male contraception closer to reality.

Researchers at Washington State University have identified a gene, Arrdc5, that is expressed only in testicular tissue and is found in multiple mammalian species, including humans. Knocking out the gene in male mice created infertility by impacting their sperm count, movement, and shape. The protein encoded by this gene is required for normal sperm production, and the team will work on designing a drug that would inhibit its production or function, making it easily reversible as a contraceptive. The discovery could pave the way for a highly effective, reversible, and non-hormonal male contraceptive for humans and animals.
