12/25 Recombination Suppression Drives Expansion of the Drosophila Dot Chromosome

Molecular Biology and Evolution, Volume 42, Issue 12, December 2025


Abstract

Genome size varies widely, even among closely related species, yet much less is known about chromosome size variation. Here we use the fourth chromosome of Drosophila, also known as the “Muller F element” or “dot chromosome”, as a model to investigate chromosome-specific size expansion. The F element of most Drosophila species is small (∼1.3 Mb) and almost entirely heterochromatic, yet harbors approximately 80...

12/25 Why do we have five fingers and toes? It all goes back to our fishy ancestors.

by Laura Kiniry, Popular Science

Published Dec 23, 2025 9:01 AM EST

The popular nursery rhyme This Little Piggy is an early childhood memory for many of us. It’s a poem that involves five little piggies, each corresponding to one of our fingers or toes. Kids love it, but if you pause to think, this simple rhyme raises a curious question: Why do humans have five digits on each of our four limbs in the first place? 

The simple answer is it’s just how we evolved, but determining where these...

11/24-SAS Researchers Make Key Advance in the Study of PTSD

Scientists from several SAS departments have created a new genetic model in mice that can be used to study psychiatric conditions such as post-traumatic stress disorder (PTSD), panic disorder, and obsessive-compulsive disorder. The research, which involves identifying a molecule that regulates dopamine, was recently published in the journal, Molecular Psychiatry. "PTSD is a debilitating illness that's extremely difficult to treat because we still do not fully understand the mechanisms behind it,"...

11/24-Researchers Zero In On Genetic Variant Tied to Miscarriages

Advances understanding of genetics causing egg abnormalities in humans 
by Kitta MacPherson

In what could be a major advance in understanding the genetic causes underlying human infertility, scientists led by researchers from Rutgers University-New Brunswick have identified a gene variant directly tied to early miscarriages in women.

The discovery of the variant is linked to accelerated reproductive aging, a condition producing high numbers of abnormal eggs that can lead to miscarriages. The...

Researchers will look at the potential health hazards of ingested plastic particles on the intestine and other organs and tissues.

Rutgers received a $3.2 million grant from the National Institutes of Health to study the impact of micronanoplastics on the digestive system.

The byproduct of environmental and industrial processes, micro- and nano-scale plastic particles and fibers increasingly contaminate the environment. These plastics — now found in our food, air and water — are a potential health...
