A new study on the heritability of autism spectrum disorder - Unsorted

Alison Campbell Jul 25, 2019

Science has known for a while now that there is a strong genetic component in autism spectrum disorders (ASD), although those opposed to vaccination tend to deny this. (David Gorski points this out in his commentary on this new 2019 paper.) In this paper, Bai et al. cite data from a meta-analysis of twin studies that estimated the heritability … Read More

Remembering Apollo 11 - Out of Space

Duncan Steel Jul 18, 2019

There are lots of ways of remembering the Apollo project, which resulted in a dozen men walking on the lunar surface (and some of them even driving around in their lunar buggies). Here I show a few of them, dear to my heart.  You may not have heard, but this weekend marks the 50th anniversary of Apollo 11, when we … Read More

  There is a lot now being talked and written about the success of Apollo 11, and the Apollo space programme, half a century ago. The BBC podcast 13 minutes to the moon is fantastic.

Most people seem to think that those images were received by the radio telescope at Parkes in New South Wales, largely because that was what … Read More

The Equation of Time - Out of Space

Duncan Steel Jul 14, 2019

The solstice on June 22nd marked the shortest duration of sunlight (or day length) during this year. One might have expected that from that date sunrise would have started getting earlier; and prior to that date sunset to have been consistently getting earlier (as the daylight duration was shortening). In fact the latest sunrise did not occur until almost a … Read More

Orbits of the satellites launched by Rocket Lab three days ago - Out of Space

Duncan Steel Jul 02, 2019

On Saturday June 29th Rocket Lab launched another cluster of seven satellites into low-Earth orbit from the Mahia Peninsula in New Zealand’s North Island. In this blog post I illustrate the orbital paths of the ten resultant tracked items now in orbit.  In a blog post last week (June 27th) I showed the orbits of the various satellites launched … Read More
