      Preprint (not peer-reviewed): Evidence for Bias of Genetic Ancestry in Resting State Functional MRI
      [not blocked]

      Someone posted this on Reddit. It purports to be a study which shows that it is possible to identify a person's genetic ancestry (in other words, their "race") by observing their brain activity.

      Thereby, we demonstrated that genetic ancestry is encoded in the functional connectivity pattern of the brain at rest. We hypothesize that these observed differences are a result of known ethnicity-related variations in head and brain morphology

      This feels problematic, in that it gives support to the racist idea that different "races" think differently. But I don't know enough myself to believe this study or debunk it. I present it for more knowledgeable people than myself to dissect and discuss.

    2. Study shows "the risk of HIV transmission through anal sex when HIV viral load is suppressed is effectively zero".

      Risk of HIV transmission through condomless sex in serodifferent gay couples with the HIV-positive partner taking suppressive antiretroviral therapy (PARTNER): final results of a multicentre,...

      Risk of HIV transmission through condomless sex in serodifferent gay couples with the HIV-positive partner taking suppressive antiretroviral therapy (PARTNER): final results of a multicentre, prospective, observational study

      Our results provide a similar level of evidence on viral suppression and HIV transmission risk for gay men to that previously generated for heterosexual couples and suggest that the risk of HIV transmission in gay couples through condomless sex when HIV viral load is suppressed is effectively zero. Our findings support the message of the U=U (undetectable equals untransmittable) campaign, and the benefits of early testing and treatment for HIV.
