More precise radiocarbon dating, secrets of hibernating bear blood, and a new book series
Anchoring radiocarbon dates to cosmic events, why hibernating bears don't get blood clots, and kicking off a book series on sex, gender, and science
First up this week, upping the precision of radiocarbon dating by linking cosmic rays to isotopes in wood. Producer Meagan Cantwell talks with Online News Editor Michael Price about how spikes in cosmic rays—called Miyake events—are helping archaeologists peg the age of wooden artifacts to a year rather than a decade or century.
Next on the show, we have a segment on why bears can safely sleep during hibernation without worrying about getting clots in their blood...

Probing beyond our Solar System, sea pollinators, and a book on the future of nutrition
On this week’s show: Plans to push a modern space probe beyond the edge of the Solar System, crustaceans that pollinate seaweed, and the latest in our series of author interviews on food, science, and nutrition
After visiting the outer planets in the 1980s, the twin Voyager spacecraft have sent back tantalizing clues about the edge of our Solar System and what lies beyond. Though they may have reached the edge of the Solar System or even passed it, the craft lack the instruments to tell us much about the interstellar medium—the space between the stars. Intern Khafia Choudhary talks with Contributing Correspondent Rich...

Scientists ’ role in the opioid crisis, 3D-printed candy proteins, and summer books
First this week, Editor-in-Chief Holden Thorp talks with author Patrick Radden Keefe about his book Empire of Pain and the role scientists, regulators, and physicians played in the rollout of Oxycontin and the opioid crisis in the United States.
Next, Katelyn Baumer, a Ph.D. student in the chemistry and biochemistry department at Baylor University, talks with host Sarah Crespi about Baumer's Science Advances paper on 3D printing proteins using candy.
Finally, book review editor Valerie Thompson takes us on a journey through some scien ce-y summer reads—from the future of foods to a biography of the color blue.

Why muon magnetism matters, and a count of all the
Host Sarah Crespi talks with Staff Writer Adrian Cho about a new measurement of the magnetism of the muon—an unstable cousin of the electron. This latest measurement and an earlier one both differ from predictions based on the standard model of particle physics. The increased certainty that there is a muon magnetism mismatch could be a field day for th eoretical physicists looking to add new particles or forces to the standard model. Also on this week’s show, Charles Marshall, director of the University of California Museum of Paleontology and professor of integrative biology, joins Sarah to talk about his team’s...

Reopening schools during the COVID-19 pandemic, and taking the heat out of crude oil separation
Contributing correspondent Gretchen Vogel talks about what can be learned from schools around the world that have reopened during the coronavirus pandemic. Unfortunately, few systematic studies have been done but observations of outbreaks in schools in places such as France or Israel do offer a few lessons for countries looking to send kids back to school soon. The United Kingdom and Germany have started studies of how the virus spreads in children and at school, but results are months away. In the meantime, Gretchen’s reporting suggests small class sizes, masks, and social distancing among the adults at school are p...

Resilience: More Than Preventing Negative Outcomes
Resilience is typically studied as either a recovery/ bouncing back factor where you return to baseline levels of functioning before an acute stressor had occurred, or as a sustainability factor where you continue performing/ adapting well despite the presence of a chronic stressor.
How resilience is typically operationalised, in terms of outcome, is whether the individual survives the acute trauma/stressor and/or chronic stress and still remains psychopathology free. If he doesn’t then he is non resilient, but if he indeed remains free of negative outcomes then he is resilient. Sometimes, very rarely, in case of...

HbA1c - when it might not be accurately measuring glycemic control
HbA1c concentration is used as the biomarker for long term glycaemic control, however if the lifespan of red blood cells is altered, that may lead to an over, or under estimation of that control.

Biochem for kids
Each time you order a test for a child, do you think the population that makes up the baseline against which the results are measured? It turns out that that historically those reference intervals have been based on adults - but children, especially neonates and adolescents, are undergoing physiological changes that mean those reference intervals may not be appropriate.
To get around this Khosrow Adeli, head and professor of clinical biochemistry at the Hospital for Sick Children, and the University of Toronto, and colleagues have undertaken a mission to recruit children and young people into a study of their test result...
