1. BYK strengthens its portfolio of measurement and testing instruments

   BYK-Gardner USA, a subsidiary of the specialty chemicals group ALTANA, is acquiring perisens GmbH.

2. Maternal diets high in UPFs may influence children’s health years later

   A narrative review of 84 publications links higher ultra-processed food intake during pregnancy and early childhood with poorer diet quality, maternal complications, childhood obesity, and potential immune, metabolic, and neurodevelopmental effects. The authors identify possible microbiome and biopsychosocial pathways but emphasize that the predominantly observational evidence cannot establish causality.

3. A wife’s account reveals the hidden burden of young-onset Alzheimer’s caregiving

   Karina Acton Reid recounts caring for her husband with young-onset Alzheimer’s disease presenting as posterior cortical atrophy while raising two young children. Her perspective shows how visual disorientation, diagnostic delays, changing family roles, and inadequate age-appropriate support affect the entire household.

4. Blood p-tau217 levels signal cognitive impairment risk years before symptoms emerge

   Higher baseline plasma p-tau217 was associated with greater 5- and 10-year risks of cognitive impairment and faster cognitive decline among 2,684 cognitively unimpaired adults. Very high levels corresponded to an estimated 38% risk at five years, but selected cohorts and limited long-term data mean routine screening and individualized prediction remain premature.

5. Timing of regenerative cues may be key to better healing from injury

   For decades, medicine has chased a simple but elusive goal of delivering the right drug to the right place at the right time.

6. Experimental drug shows promise against NRAS-driven melanoma

   A research team from Huntsman Cancer Institute at the University of Utah (the U) reports that a groundbreaking pathway-targeted therapy could be an effective treatment for certain melanoma patients and fill an unmet clinical need for patients with advanced disease.

7. New approach enhances radiotherapy by disabling cancer's DNA repair machinery

   Cancer treatments like radiation and chemotherapy work by doing one main thing: shredding the DNA of cancer cells so they can no longer multiply.

8. LIG1 loss reveals new treatment strategy for aggressive breast cancer

   Loss of one copy of the DNA Ligase I (LIG1) gene in triple-negative breast cancers (TNBC) with TP53 mutations confers resistance to chemotherapy, but researchers at Baylor College of Medicine and collaborating institutions have identified a vulnerability in these cells and used it to their advantage.
