Clock disruption speeds breast cancer in models
New research finds that repeating disruption of the body’s 24-hour clock changes breast tissue, weakens immune defenses and leads to faster, more aggressive breast cancer in experimental models. The study links altered light–dark schedules to worse outcomes.
Older adults more exposed to low-credibility online health information
Researchers at the University of Utah tracked web activity of more than 1,000 US adults for four weeks. They found low-credibility health sites were rare overall but visits were concentrated among older adults, especially those who lean right politically.
Blood biomarkers for inflammatory breast cancer
Researchers have found blood-based biomarkers that can distinguish inflammatory breast cancer (IBC) from other breast cancer types. Using a robust RNA method, the discovery could allow earlier detection, easier monitoring and help guide new treatments.
