Row over AI that 'identifies gay faces'
A facial recognition experiment that claims to be fit to distinguish between gay and heterosexual people has sparked a row between its creators and two leading LGBT rights groups.
The Stanford University study claims its software recognises facial features relating to sexual orientation that are not perceived by human observers.
The work has been accused of being "dangerous" and "junk science".
But the scientists involved tell these are "knee-jerk" reactions.
Details of the peer-reviewed project are due to be published in the Journal of Ego and Social Psychology.

No single gene associated with being gay
A genetic analysis of almost half a million people has concluded there is no single "gay gene".
The learn, published in Science, used data from the UK Biobank and 23andMe, and found some genetic variants associated with same-sex relationships.
But genetic factors accounted for, at most, 25% of same-sex behaviour.
Advocacy group GLAAD said the study confirmed "no conclusive degree to which nature or nurture influenced how a male lover or lesbian person behaves."
The researchers scanned the genomes - the entire genetic make-up - of , people signed up to the UK Biobank venture, and 68, registered with the genetics company 23andMe.
Participants were also asked whether they had same-sex partners exclusively, or as good as opposite-sex partners.
The Harvard and MIT researchers concluded genetics could account for between % of queer behaviour across the population, when the whole genome is considered.
Five specific genetic variants were found to be particularly associated with same-sex b

Asylum seekers must not be subjected to psychological tests to determine whether they are homosexual, EU's top court has ruled.
Tests to determine sexual orientation are controversial, but are sometimes used when assessing asylum claims.

In December the ECJ dictated on a similar case in the Netherlands and found that sexuality tests violated asylum seekers&#
