What if one framework could connect the different “stories” written into a tumor’s DNA? This Nature paper identifies integrated mutational footprints (IMFs) that capture key DNA-damage and repair processes in prostate cancer genomes, including links to replication stress and androgen-receptor–mediated mutagenesis. The study also explores how these signatures relate to metastasis timing and predicted drug sensitivity.

What happens to someone who misses an HIV care visit—do they feel able to come back? This open-access analysis from Zambia suggests that improving the “caring” experience from healthcare workers can boost return after interruptions and help people stay engaged once they return. It’s a hopeful, practical look at reengagement, built from real clinic data. Explore the study: https://journals.plos.org/plosmedicine/article/file?id=10.1371/journal.pmed.1005052&type=printable

What if some of California’s biggest winter rainstorms start thousands of miles away? This study connects record-breaking precipitation in 2016–2017 and 2022–2023 to early-winter warming over the Tibetan Plateau, even during La Niña years when California is often expected to be drier. By improving how the model “sees” Tibetan Plateau temperatures, the researchers reproduce a large fraction of the observed extreme rainfall.

After prostate cancer, it’s not just whether you eat “healthy”—it’s what kind of fat you’re getting. This open-access study looked at diet after diagnosis and found saturated/animal fats were tied to higher overall death risk, while plant-based fats and monounsaturated fats were linked to better survival. Curious what this could mean for everyday choices?

Where are bladder cancer clinical trials located—and who’s left out? This study of ClinicalTrials.gov data finds that most US counties (77%) have no bladder cancer trial sites, and that trial availability clusters in areas with higher incidence and lower social vulnerability. It also explores how mortality and trial sponsor/size relate to location.

From our sister site: What's the deal with Raw Milk......

For most of the last century, pasteurization has been one of public health’s quieter success stories. Milk is heated for a short period, disease-causing microorganisms are dramatically reduced, and the milk that reaches consumers retains essentially the same major nutrients. That arrangement did n...

Did the gigantic Toba eruption 74,000 years ago devastate eastern Africa’s climate for decades? New research with detailed annual data reveals the eruption triggered only a brief period of cooling and drought. This challenges older views and sheds light on ancient climate dynamics.
