The Download: GLP-1s and eating disorders, self-aware cities, and forever chemicals

GLP‑1–based drugs, which have revolutionised obesity and diabetes treatment, are now being flagged as a potential contributor to eating‑disorder pathology. A recent report shows that the global prevalence of anorexia and bulimia rose by 71 % from 1990 to 2023, and clinicians are already noting that these medications may amplify restrictive and compulsive behaviours in vulnerable patients.

In the cultural section, writer Charlie Jane Anders introduces “Love is Infrastructure,” a short narrative in which two neighbouring cities gain self‑awareness through the direct involvement of their residents. The story examines how interactions between conscious cities can create unexpected relationships and raises questions about urban efficiency versus collective autonomy.

Finally, the article reviews the state of research on PFAS, the so‑called “forever chemicals.” These substances, found in non‑stick cookware and fire‑fighting foams, are linked to fertility problems, cancer, and immune disorders. While complete elimination remains nascent, new methods are being developed to extract PFAS from water and soil, potentially curbing environmental accumulation.

These stories illustrate how medical and technological progress can produce unforeseen side effects, while the fight against persistent pollutants remains essential for public health and the environment.
