Mixed physical and mental fatigue cut badminton smash speed 10.6 percent and accuracy 46.1 percent
As fatigue deepened, accuracy dropped fast and a speed-accuracy trade-off appeared under moderate to severe fatigue. When physical and mental fatigue were induced together, badminton forehand smash performance fell sharply, especially accuracy. From baseline to severe fatigue, smash speed dropped 10.6% and accuracy dropped 46.1%. Under moderate-to-severe fatigue, hitting faster was linked to worse accuracy, […]
Virtual reality did not significantly change rowing muscle fatigue in trained men during ergometer exercise
In this pilot test, a natural river simulation did not measurably slow lower-limb fatigue by electromyography. In a small pilot study of trained male rowers, virtual reality did not significantly change lower-limb muscle fatigue during rowing ergometer exercise. Fatigue patterns looked broadly similar with and without a naturalistic virtual environment. The authors stress the result […]
Nasal temperature drops during stress, especially social speech stress
Thermal video of the nose tracked an objective “stress dip,” and it lined up with body-type anxiety symptoms more than self-rated stress. In healthy adults, nasal skin temperature dropped during two lab stressors and rebounded during recovery, but did not fully return to baseline in five minutes. A speech-based social stressor produced a bigger temperature […]
High-flow nasal therapy costs more than low-flow oxygen in COAST
In Kenyan and Ugandan children with severe pneumonia and low blood oxygen, higher-tech oxygen delivery increased costs without better outcomes. In the COAST trial, high-flow nasal therapy cost more than low-flow oxygen for children with severe hypoxaemia. For children with less severe hypoxaemia, both high-flow nasal therapy and low-flow oxygen cost more than permissive hypoxaemia. […]
LIVEBORN newborn resuscitation feedback proved feasible and usable
In two Democratic Republic of the Congo facilities, an observer-led mobile health tool reached feasibility for observing births, with mixed results for debriefing uptake. LIVEBORN, a mobile health application designed to give real-time guidance and support debriefing during newborn resuscitation, was feasible to use for observing births in two facilities. In this pilot, 74% of […]
Self-centered reflection increased sense of agency; selfless reflection decreased it
A pilot experiment linked reflection style to agency and distinct EEG complexity patterns. In [Self-reflection, sense of agency, and underlying neural correlates: A pilot study], self-centered self-reflection increased an implicit measure of sense of agency, while selfless reflection reduced it. The researchers measured agency using intentional time binding, a timing-based method for assessing how people […]
Teachers on the Front Line of Bullying What Drives Action and What Gets in the Way
Why stopping bullying depends on what teachers face every day Bullying does not just bruise bodies—it can erode trust, learning, and mental health across an entire school. In most cases, the adult in the best position to interrupt it is the classroom teacher. Yet even committed teachers do not always step in quickly or effectively. […]
Turning Heartbreak Into a Story: How Writing About a Breakup Changes What You Remember and Expect Next
Why Putting Heartache Into Words Can Shift Your Next Chapter Breakups don’t just sting; they scramble our sense of who we are, what happened, and what could ever come next. Many of us cycle through the same fragments—texts, arguments, “what ifs”—without finding much clarity. This is where the new research paper The effects of narrative […]
Why Some Mental Health Apps Stick While Others Don’t: Lessons from People Using PolarUs for Bipolar Self‑Management
When Help Fits in Your Pocket but Life Gets in the Way Mobile apps promise support for people living with bipolar disorder—tools to track mood, spot early warning signs, and practice coping strategies. Yet many of us download an app, try it for a week, and then forget it exists. That drop-off matters. For bipolar […]
Belonging as Infrastructure: What Families Teach Us About Building Inclusive Communities
Belonging Is a Safety Net, Not a Luxury When life becomes uncertain, what keeps people steady is often not just grit, but belonging—feeling connected, respected, and able to take part in everyday life. The research paper Understanding social inclusion: A directed content analysis shows that inclusion works like community infrastructure: when it’s strong, families can […]
