Top Science Podcasts: Earthworm Study, Bias In Health Algorithms & “Dr. Space Junk” (ScienceMag)

scimag_pc_logo_120_120 (1)This week in ScienceHelen Philips, a postdoctoral fellow at the German Centre for Integrative Biodiversity Research and the Institute of Biology at Leipzig University, and colleagues published the results of their worldwide earthworm study, composed of data sets from many worm researchers around the globe. 

Sarah also talks with Ziad Obermeyer, a professor in the School of Public Health at the University of California, Berkeley, about dissecting out bias in an algorithm used by health care systems in the United States to recommend patients for additional health services.

Finally, in the monthly books segment, books host Kiki Sanford interviews author Alice Gorman about her book Dr. Space Junk vs The Universe: Archaeology and the Future. Listen to more book segments on the Science books blog: Books, et al.

Neuroscience Podcast: “Consciousness Theories” And “Biased Childhood Memories” (ScienceMag)

We don’t know where consciousness comes from. And we don’t know whether animals have it, or whether we can detect it in patients in comas. Do neuroscientists even know where to look? A new competition aims to narrow down the bewildering number of theories of consciousness and get closer to finding its biological signs by pitting different theories against each other in experimental settings. Freelance journalist Sara Reardon talks with host Sarah Crespi about how the competition will work.

Science Mag Podcast ConsciousnessIn our second segment, we talk about how we think about children. For thousands of years, adults have complained about their lack of respect, intelligence, and tendency to distraction, compared with previous generations. A new study out this week in Science Advances suggests our own biased childhood memories might be at fault. Sarah Crespi talks with John Protzko of the University of California, Santa Barbara, about how terrible people thought kids were in 3800 B.C.E. and whether understanding those biases might change how people view Generation Z today.

50th Anniversary Of Apollo 11: “The Moon Miracle” By Thom Gibbs Is A Spectacular Chronology

From a Telegraph.co.uk online article by Thom Gibbs:

The Moon Miracle by Thom Gibbs The Telegraph Chronology 2The first question is often ‘why haven’t we been back?’ Fifty years since humans stepped onto the surface of a foreign planetary body there has not been another event to rival it. Not in space, nor back here on Earth.
There have been enormous leaps forward. The Large Hadron Collider, the internet, the fidget spinner, but there is no match for the romance of our first moonshot. It is quite possibly the only achievement of our time which will be remembered centuries from now.
The audacity and aesthetics of Neil Armstrong, Buzz Aldrin and Mike Collins’s journey still resonate. Their mission was so perilous that Richard Nixon had a speech drafted in the event the astronauts did not come home. “Fate has ordained that the men who went to the Moon to explore in peace will stay on the Moon to rest in peace,” it read. “These brave men… know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice.”
