Top New Science Podcasts: Blood Tests For Multiple Cancers, Our Quiet Sun
Staff Writer Jocelyn Kaiser joins Sarah to talk about a recent Science paper describing the results of a large study on a blood test for multiple types of cancer. The trial’s results suggest such a blood test combined with follow-up scans may help detect cancers early, but there is a danger of too many false positives.
And postdoctoral researcher Timo Reinhold of the Max Planck Institute for Solar System Research joins Sarah to talk about his paper on how the Sun is a lot less variable in its magnetic activity compared with similar stars—what does it mean that our Sun is a little bit boring?

Top New Science Podcasts: ‘Sniff-Response’, Carbon Dioxide And Vaccinations Replacing Antibiotics
This week, how the ‘sniff-response’ can help clinicians determine a patient’s state of consciousness, and how vaccines could help drive down antibiotic use.
In this episode:
00:45 Sniffing out consciousness
Researchers have found that the sniff reflex can indicate whether a patient is in a vegetative state, and even the likelihood that they will recover consciousness. Research Article: Arzi et al.
08:37 Research Highlights
The stupefying effect of carbon dioxide, and a chameleon gemstone that tricks your eyes. Research Highlight: Rising carbon dioxide levels will make us stupider; Research Highlight: How a chameleon gemstone changes from red to green
11:12 Vaccination and antibiotic usage
Looking at data from low- and middle-income countries, researchers have determined that vaccination could prevent millions of infections currently treated by antibiotics. Research Article: Lewnard et al.
16:49 Pick of the Briefing
We pick our highlights from the Nature Briefing, including the forgotten mother of climate change science, and a new global study on insect declines.

Coronavirus: Race To Expand Antibody Testing And Investing In Public Health (Nature Podcast)
Benjamin Thompson, Noah Baker, and Amy Maxmen discuss the role of antibody tests in controlling the pandemic, and how public-health spending could curtail an economic crisis. Also on the show, the open hardware community’s efforts to produce medical equipment.
In this episode:
02:08 Betting on antibodies
Antibody tests could play a key role in understanding how the virus has spread through populations, and in ending lockdowns. We discuss concerns over their reliability, how they could be used, and the tantalising possibility of immunity.
News: The researchers taking a gamble with antibody tests for coronavirus
10:25 Economy vs public health, a false dichotomy
Jim Yong Kim, former president of the World Bank, argues that strong investment in public health is crucial to halt the ongoing pandemic and to prevent a global financial crisis. We discuss his work with US governors to massively increase contact tracing, and his thoughts on how researchers can help steer political thinking.

19:00 One good thing this week
Our hosts talk about staying positive, and pick a few things that have made them smile in the last 7 days, including a tiny addition to the team, a newspaper produced by children in lockdown, and a gardening update.
Six Feet of Separation, the newspaper staffed by kids
22:51 Open hardware
Researchers are stepping up efforts to design and produce ventilators and personal protective equipment for frontline medical staff. We hear how the open hardware movement is aiding these efforts, and the regulations that teams need to consider if their designs are to make it into use.
Astronomy: Hubble Space Telescope Celebrates 30th Anniversary April 24
On April 24, 2020, the Hubble Space Telescope celebrates its 30th year in orbit by premiering a never-before-seen view of two beautiful nebulas named NGC 2020 and NGC 2014.
Hubble’s senior project scientist, Dr. Jennifer Wiseman, takes us on a tour of this stunning new image, describes the telescope’s current health, and summarizes some of Hubble’s contributions to astronomy during its 30-year career.
New Science Podcasts: How Coronavirus Kills People, Quantum Diamond Microscopes & Magnetism
Coronavirus affects far more than just the lungs, and doctors and researchers in the midst of the pandemic are trying to catalog—and understand—the virus’ impact on our bodies. Staff Writer Meredith Wadman joins host Sarah Crespi to discuss what we know about how COVID-19 kills. See all of our News coverage of the pandemic here, and all of our Research and Editorials here.
Also this week, Staff Writer Paul Voosen talks with Sarah about quantum diamond microscopes. These new devices are able to detect minute traces of magnetism, giving insight into the earliest movements of Earth’s tectonic plates and even ancient paleomagnetic events in space.

Top Science Podcasts: Our Ancient Hominin Species DNA, Vikings, Lemur Love & “Gargantuan” Hail Stones
23 April 2020: Denisovan DNA in modern Europeans, and the birth of an unusual celestial object. This week, evidence of ancient hominin DNA in modern human genomes, and the origin of a snowman-shaped object at the edge of the solar system.
In this episode:
00:45 Intermixing of ancient hominins
By combing through the DNA of over 27,000 modern day Icelanders, researchers have uncovered new insights about the ancient hominin species who interbred with Homo sapiens. Research Article: Skov et al.
08:05 Research Highlights
The scent of lemur love, a hidden Viking trade route, and ‘gargantuan’ hail. Research Highlight: Lemurs’ love language is fragrance; Research Highlight: Vikings’ lost possessions mark a long-hidden early trade route; Research Highlight: Enormous hailstones inspire a new scientific size category: ‘gargantuan’
11:44 The origin of Arrokoth
In 2019, the New Horizon Spacecraft took images of Arrokoth – an unusual, bi-lobal object found in the Kuiper belt. Now, researchers believe they’ve figured out how it formed. Research Article: Grishin et al.
17:29 Pick of the Briefing
We pick some highlights from the Nature Briefing. This week we discuss why the Universe may be lopsided, and why water could actually be two different liquid states. Scientific American: Do We Live in a Lopsided Universe?; Chemistry World: The weirdness of water
