Slimy hagfish help solve mysteries of genome duplication
With an eyeless face and slimy body that only a mother could love, hagfish fascinate many biologists. These eel-like, jawless vertebrates have now helped scientists solve a major evolutionary mystery: When did vertebrate genomes double in size and what happened as a result?
It’s long been known that in the past, various plants and animals duplicated all their genes in one fell swoop. By sequencing hagfish genomes for the first time, two teams working independently have clarified when two of these genomic upheavals occurred in the early history of vertebrates. In addition to helping explain some of the hagfish’s u...

High body fat raises fracture risk in women treated for breast cancer
Women with high body fat undergoing early breast cancer treatment may be at higher risk for vertebral fractures, despite the use of bone health drugs, according to a study published January 10 in JAMA Network Open.
In a study of patients who received aromatase inhibitors and denosumab over four years, dual-energy x-ray absorptiometry (DEXA) scans showed that high baseline fat body mass was independently associated with vertebral fractures after 18 months, wrote lead author Deborah Cosentini, MD, of the University of Brescia in Italy, and colleagues.
“These findings suggest that fat body mass may promote skeletal fragil...

Efforts to Restrict Transgender Health Care Endure in 2024
Republican-led state legislatures are considering a new round of bills restricting medical care for transgender youths—and in some cases, adults—returning to the issue the year after a wave of high-profile bills became law and sparked lawsuits.
As legislatures begin their work for the year, lawmakers in several states have proposed enacting or strengthening restrictions on puberty-blocking drugs and hormone treatments for minors. Bills to govern the pronouns kids can use at school, which sports teams students can play on, and the bathrooms they can use are back, as well, along with efforts to restrict drag p...
