The incidence of advanced prostate cancer in California rose markedly in the decade since doctors stopped routinely screening all men for the disease, according to a new study by UC San Francisco.

University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on the evolutionary tree. That makes it one of the oldest known animal sex chromosomes. The finding also is evidence that octopuses and other cephalopods, a class of sea animals that includes squid and nautiluses, do use chromosomes to determine their sex, answering a longstanding mystery among biologists.  

A national study seeking more effective treatment for deadly metaplastic breast cancer has identified two inhibitor drugs with the potential to interrupt disease progression.

New research from the University of Minnesota and Boston University School of Public Health (BUSPH) shows that death rates for early adults, or adults aged 25-44, rose sharply during the COVID-19 pandemic and remain higher than expected post-pandemic. Heightened death rates during the COVID-19 pandemic intensified an already negative trend for early adults, which began around 2010. As a result, early adult death rates in 2023 were about 70 percent higher than they might have been if death rates had not begun to rise about a decade before the pandemic. 

A new study from Moffitt Cancer Center could help doctors predict how well patients with a specific type of lung cancer will respond to new therapies. The research, published in Clinical Cancer Research, found that measuring the interaction between two proteins, RAS and RAF, could provide valuable insights into the effectiveness of treatments for patients with KRASG12C-mutant non-small cell lung cancer, a type of lung cancer known for being particularly difficult to treat.
