Tickling, or gargalesis, still puzzles neuroscience, finds a new review. We do not know how a touch becomes ticklish or why we respond to other people’s tickles but not our own. Gargalesis is likely the earliest trigger for laughter in life, but it is unclear whether we laugh because we enjoy it.

Sex chromosomes affect longevity & may also affect resilience in health span. Women live longer than men and exhibit less cognitive aging. A group reports that they have found a gene in mice that rejuvenates female brains. This gene was increased in the aging hippocampus of female mice & women.

Scientists have extracted microplastics from the sand of 22 beaches in New Zealand. Almost all of the particles were smaller than a dust mite (<300 μm). However the study could only detect particles larger than a human skin cell (32 μm), so there's likely even more plastic in the sand.

Strength of immune-system response may drive healthy aging. A resilient immune system is able to minimize inflammation anywhere in the body. People with strong immune resilience at age 40 years had a 15.5-year survival advantage over those with low resilience at that age, the study found.

Younger men are less likely to seek professional help for their health. Men aged 18-29 were the least likely, often seeking help from online sources or their own networks. Barriers include cost and logistics, stigma around mental health and a fear of compromising independence by asking for help.
