Population Decline of Franklin’s Bumble Bee Wasn’t Due to Pathogens, Museum Genomic Research Shows

Andy Fell — October 20, 2025 - 3:38pm

Franklin’s bumble bee (Bombus franklini) once inhabited a remote area spanning northern California and southern Oregon. But the bee’s numbers declined sharply after 1998 and it hasn’t been seen at all since 2006. A new study of the DNA of museum specimens, published this week in Proceedings of the National Academy of Sciences, suggests this decline was most likely due to population bottlenecks and environmental issues such as fire and drought rather than infectious diseases.

Finding Human Brain Genes in Duplicated DNA

Andy Fell — July 21, 2025 - 11:04am

What makes the human brain distinctive? A new study published July 21 in Cell identifies two genes linked to human brain features and provides a road map to discover many more. The research could lead to insights into the functioning and evolution of the human brain, as well as the roots of language disorders and autism.

How 3D folding of DNA inside germ cells sets them on the path to become sperm.

No Evidence of a Common Set of Regeneration Genes

Andy Fell — August 19, 2024 - 2:57pm

Some animals, especially those that have been around for a long time in evolutionary terms, possess extraordinary abilities to regenerate lost limbs or organs. These animals, such as flatworms, salamanders and zebrafish, are not at all closely related, suggesting that the ability to regenerate goes far back in evolutionary time. Is it possible to find a common set of genes for regeneration, that could unlock a new understanding of this process?

More Than Meows: How Bacteria Help Cats Communicate

Andy Fell — November 15, 2023 - 10:15am

Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study from the University of California, Davis, shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands. The work was published Nov. 8 in Scientific Reports.

51�ԹϺ�� Davis Researchers Unlock Valuable Information in Chicken Genome

Andy Fell — May 04, 2023 - 3:03pm

Chickens provide one of the world's most popular animal proteins, with billions of birds grown every year for eggs and meat. Interpreting the farm animal’s genome is vital for understanding how genes control traits, such as growth, feed efficiency, reproduction and disease resistance.

Zoonomia Consortium Unveils Mammal Genomes, Creates Evolutionary Timeline

Andy Fell — April 27, 2023 - 11:00am

Mammals are an extraordinarily diverse and successful group of animals, from the tiniest pygmy shrew to the mighty blue whale, and including, of course, ourselves. In a special issue of the journal Science published today (April 27), the Zoonomia Consortium shows how comparing the genomes of 240 modern mammals sheds light on mammalian evolution, with implications for conservation and understanding human and animal health.

Revealing the Genome of the Common Ancestor of All Mammals

Andy Fell — September 27, 2022 - 9:30am

Every modern mammal, from a platypus to a blue whale, is descended from a common ancestor that lived about 180 million years ago. We don’t know a great deal about this animal, but the organization of its genome has now been computationally reconstructed by an international team of researchers. The work is published Sept. 30 in Proceedings of the National Academy of Sciences.

Genomics by Africans for Africans

Andy Fell — March 15, 2022 - 11:49am

The African BioGenome Project (AfricaBP) has published a position paper in Nature highlighting the goals, priorities, and roadmap of the Africa-led effort to sequence the genomes of 105,000 species of plants, animals, fungi and protists that are endemic to the continent.

Sequencing Puts Carnivore Chromosomes in Context

Andy Fell — February 21, 2022 - 4:28pm

Studies comparing animal genomes generally focus on the DNA sequence itself. A new study by researchers at the University of California, Davis shows how the three-dimensional scaffolding of chromosomes is related across several species of carnivores, offering a new approach of “comparative scaffotyping” that could be used to identify related genes across species and place them in context. The work, published the week of Feb.
