What do you do when you're call blasting Bigfoot in eastern Washington, a pool of mysterious blood shows up in your tent and you can't find any answers? You call in Dr. @SimeonHein and his remote viewers. Then, for verification, you call in Intuitive TishPaquette at the

π§¬π₯ Do the genetics that make you develop a disease also help you survive it? Not much. Our new @NatureGenet including 9 disease and 7 biobanks shows: β’ Susceptibility variants β survival β’ PRSs for onset weak at predicting survival β’ Lifespan PRS predicts survival better

Why do some people never have #sex, even later in life? A new study, conducted by @amsterdamumc and @UQ_News alongside researchers of our Institute, explores this fascinating question. Check out theΒ @PNASNews paper here:Β https://t.co/em2qUk5irY

@laurawesseldijk Brendan Zietsch wrote a good and accessible summary of our paper here:
theconversation.com
A study of more than 400,000 people found 1% had never had sex β which was linked to a range of genetic, environmental and other factors.

Sexlessness is relevant to wellbeing and evolution. But itβs also a complex behavioral trait: its genetic associations trace back to many other traits and environments. The associations we find are correlational and likely to be culture-specific, so more research is needed.

Genes linked to sexlessness overlap with genes associated with: - Higher education & IQ - Less substance use - Higher autism & anorexia risk - Lower ADHD, anxiety, depression & PTSD risk

Thousands of genetic variants with very tiny effects together explain ~15% of variation. The genetic correlation between men and women is .56. Ancient DNA shows an allele significantly associated with sexlessness declined over 12,000 years, consistent with natural selection.

Where you live matters too. Men in regions with fewer women were more likely to be sexless. Sexlessness was also more common in regions with higher income inequality.

Sexless individuals reported: - More loneliness, nervousness, unhappiness - Fewer close relationships & social connections - Less alcohol & drug use Patterns differed by sex: for men, physical strength, income, and social connection mattered more.

Sex is central to human wellbeing. ~1% of people never have sex. While some people simply donβt want sex, for others, no partner can mean loneliness, lower wellbeing, or even economic disadvantage. No sex is also interesting for genetics as it is an evolutionary βdead endβ.
