8 Researchers identify nerve network that fuels triple-negative breast cancer¶
Researchers at the University of Oklahoma discovered that triple-negative breast cancer tumors recruit macrophages that release BDNF, a protein drawing nerves into tumors and supporting cancer progression. In mouse models, blocking BDNF signaling prevented nerve infiltration and significantly reduced tumor growth, with patient data showing higher macrophage and BDNF levels associated with poorer survival.
- Macrophages release BDNF protein that draws nerves into tumors
- Blocking BDNF signaling reduced tumor growth in mice
- Higher macrophage and BDNF levels linked to poorer survival in patients

7.5 AI Rapidly Discovers New Treatments for Previously Incurable Diseases¶
Artificial intelligence is accelerating drug discovery for diseases including Parkinson's disease, antibiotic-resistant infections, and rare lung diseases.
- MIT researchers screened 45 million compounds using generative AI trained on antibiotic structures
- AI discovered two compounds effective against Neisseria gonorrhoeae and Staphylococcus aureus (MRSA)
- Only 12 new antibiotics approved 2017–2022; AI can screen massive libraries in days or hours
- 1.1 million annual deaths from antibiotic-resistant infections; projected 8+ million by 2050 without intervention

7 Novel Protein-Blocking Compound Shows Promise Against Alzheimer's in Mice¶
Researchers at ETH Zurich developed an experimental compound called Compound 10 that blocked a protein-aggregating enzyme linked to Alzheimer's disease in mouse models. The treatment prevented amyloid beta accumulation, slowed nerve cell death, extended lifespan, and showed signs of anti-aging effects in treated animals.
- Compound 10 blocks GRK2 enzyme aggregation
- Prevented amyloid beta accumulation in mouse brains
- Slowed nerve cell death and extended animal lifespan
- Research published in Cell Reports Medicine

7 Low-fat vegan diet promotes weight loss without calorie restriction¶
A 16-week randomized clinical trial found that adults following an ad libitum low-fat vegan diet consumed approximately 357 fewer calories per day without explicit calorie restriction or portion-size limits. The vegan diet reduced energy density by about 30% by replacing calorie-dense animal foods with plant foods containing more water and fiber.
- Participants consumed 357 fewer calories per day without counting calories
- Energy density reduced by approximately 30 percent
- Total weight of food consumed remained essentially unchanged
- Study led by Hana Kahleova, MD, PhD at Physicians Committee for Responsible Medicine

7 Trump administration implements vaccine agenda overhaul via executive order¶
The president of the United States signed an executive order reshaping federal vaccine policy amid criticism from the WHO and vaccine manufacturers' refusal to comply. Accompanying health policy actions included new FDA food additive notification requirements, a ban on federal Medicaid and CHIP coverage for gender-affirming care for minors, and an addiction toolkit emphasizing faith-based interventions over harm reduction.
- Executive order reshapes vaccine policy with limited evidentiary support
- WHO criticized the order; vaccine manufacturers signaled non-compliance
- CMS banned federal Medicaid/CHIP coverage for gender-affirming care for minors
- New FDA requirements for food additives to demonstrate safety
- Addiction toolkit de-emphasizes harm reduction despite methadone's overdose mortality evidence
