- Open-label placebo group received a fake supplement but were told it was a placebo; after three weeks it reported lower perceived stress, better short‑term memory, higher psychological well‑being, more optimism, and improved physical performance versus a deceptive placebo and a no‑intervention control.
- Aarhus University researchers interviewed 104 children about play and then surveyed 504 children, identifying seven core “play qualities” (social inclusion, imagination, transgression, accessibility, wild/exciting play, having something to do, and “play feeling”) that distinguish good from bad play experiences.
- Project CETI scientists recorded six hours of underwater audio and drone footage of a sperm whale birth off Dominica in 2023, documenting coordinated assistance from kin and non‑kin whales and vocal shifts, including vowel‑like sounds, during the birthing process.
- International Journal of Clinical and Health Psychology published the placebo study, noting that the open‑label group’s improvements occurred despite participants knowing the supplement was fake.
Why it matters: Older adults gain a simple, low‑cost way to boost mental and physical health without active medication, while clinicians can use open‑label placebos to improve outcomes without deception. The findings challenge the belief that deception is required for placebo efficacy in clinical practice.
