Two heart nerve cell types sustain cardiac stability in mice

Researchers identified two major intrinsic cardiac neuron populations in mice: Npy-positive neurons regulate parasympathetic heart rate control and support coronary perfusion, while Ddah1-positive neurons help maintain electrical stability during extreme stress. Removing Npy-positive neurons caused fatal cardiac failure, whereas loss of Ddah1-positive neurons increased susceptibility to malignant arrhythmias and sudden cardiac arrest under stress.

A 10-minute evening skincare massage may help women sleep better and feel less anxious

Four weeks of a 10-minute evening cosmetic routine with self-massage improved self-reported sleep quality, state anxiety, mental health, and vitality in women with sleep complaints compared with usual routines. Exploratory wearable data showed longer total and deep sleep on rest days, but the non-randomized design and absence of wearable controls limit causal conclusions.

Aligned heart rates indicate real-world social connection and engagement

When people are close-both physically and emotionally-their heart rates begin to align, rising and falling together. Could such cardiac alignment be used as a way to measure social engagement and connection in everyday settings? Hanlu He and colleagues used data collected by 72 students visiting New York City as part of an audio engineering competition.

Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.
