Mutations linked to autism may be detectable in men’s sperm

An advanced DNA-sequencing technique has identified gene-damaging mutations, some with ties to autism, in about 1 in 15 men.

Parental age plays small role in large mutations tied to autism

Most of the large, spontaneous genetic mutations tied to autism are passed down from fathers. But, unlike with smaller mutations, a parent's age is unlikely to up the rate at which they occur.

The link between parental age and autism, explained

Older men and women are more likely than young ones to have a child with autism, but this connection is not straightforward.

Mutations in sperm may accrue too slowly to increase autism risk

A new analysis challenges the idea that mutations in the sperm of older fathers lead to higher rates of autism among their children.

Ultrasound exposure; maternal age; ‘special’ interests and more

Autism is not associated with ultrasound frequency or duration, maternal age and education affect autism odds, and people on the spectrum benefit from their ‘special interests.’

Genetics do-over; iffy influences; high-tech education and more

A re-analysis of data yields an increased estimate for the genetic contribution to autism, how the environment might contribute to autism is hard to pin down, and students on the spectrum describe the benefits of using technology at school.

Null and Noteworthy: Neurons tracking sequences don’t fire in order

Instead, neurons encode the position of sequential items in working memory based on when they fire during ongoing brain wave oscillations—a finding that challenges a long-standing theory.

How to teach this paper: ‘Neurotoxic reactive astrocytes are induced by activated microglia,’ by Liddelow et al. (2017)

Shane Liddelow and his collaborators identified the factors that transform astrocytes from their helpful to harmful form. Their work is a great choice if you want to teach students about glial cell types, cell culture, gene expression or protein measurement.
