Top Science Podcasts: Orbiting A Black Hole, Parrots And Online Media Consumption (Nature)

Nature PodcastsListen to the latest from the world of science, brought to you by Benjamin Thompson and Nick Howe. This week, observations of objects orbiting a black hole, and rethinking how we measure screen-time.

In this episode:

00:45 Observing the centre of the galaxy

Researchers have uncovered a population of dust-enshrouded objects orbiting the supermassive black hole at the centre of the galaxy. Research Article: Ciurlo et al.

09:00 The human ‘screenome’ project

To understand the effects of online media consumption, researchers argue that the way it’s measured needs to change. Comment: Time for the Human Screenome Project

Top Science Podcasts: Measles Wipes Out Immune System Memory, Black Holes (Science Magazine)

scimag_pc_logo_120_120 (2)Measles is a dangerous infection that can kill. As many as 100,000 people die from the disease each year. For those who survive infection, the virus leaves a lasting mark—it appears to wipe out the immune system’s memory. News Intern Eva Fredrick joins host Sarah Crespi to talk about a pair of studies that looked at how this happens in children’s immune systems.

In our second segment this week, Sarah talks with Todd Thompson, of Ohio State University in Columbus, about his effort to find a small black hole in a binary pair with a red giant star. Usually black holes are detected because they are accruing matter and as the matter interacts with the black hole, x-rays are released. Without this flashy signal, black hole detection gets much harder. Astronomers must look for the gravitational influence of the black holes on nearby stars—which is easier to spot when the black hole is massive. Thompson talks with Sarah about a new approach to finding small, noninteracting black holes.
