Covid-19: ‘The Variant Hunters’ – Understanding Its Spread (Cambridge)

The variant hunters are helping us to understand how and why the COVID-19 virus is spreading, allowing us to fight back against the COVID-19 pandemic.

Hear from some of the scientists behind the UK’s nationwide sequencing effort to track SARS-CoV-2. Sir Patrick Vallance (the government’s Chief Scientific Adviser) also describes how the expertise that came together during the pandemic is now recognised across the world – and why it’s crucially important to continue to sequence to be ready for future pandemics.

This pioneering work is being carried out by the COVID-19 Genomics UK (COG-UK) consortium, which comprises numerous academic institutions, four public health agencies and the Wellcome Sanger Institute, and is administered by the University of Cambridge.

“Incredibly impressive, incredibly high quality and incredibly focused on the mission to make sure that as many people benefited from the science as possible,” Sir Patrick Vallance.

Science: Whole-Genome Screening For Newborns, Active Learning For STEM

Today, most newborns get some biochemical screens of their blood, but whole-genome sequencing is a much more comprehensive look at an infant—maybe too comprehensive?

Staff Writer Jocelyn Kaiser joins host Sarah Crespi to discuss the ethical ins and outs of whole-genome screening for newborns, and the kinds of infrastructure needed to use these screens more widely. Sarah also talks with three contributors to a series of vignettes on the importance of active learning for students in science, technology, engineering, and math. Yuko Munakata, professor in the department of psychology and Center for Mind and Brain at the University of California, Davis, talks about how the amount of unstructured time and active learning contributes to developing executive function—the way our brains keep us on task. Nesra Yannier, special faculty at Carnegie Mellon University and inventor of NoRILLA, discusses an artificial intelligence–driven learning platform that helps children explore and learn about the real world. Finally, Louis Deslauriers, senior preceptor in the department of physics and director of science teaching and learning at Harvard University, laments lectures: why we like them so much, why we think we learn more from lectures than inquiry-based learning, and why we’re wrong.

Science & Medicine: Story Behind The mRNA Vaccines

As mRNA-based COVID-19 vaccines are deployed to protect hundreds of millions of people across the world from the deadly global pandemic, the University of Pennsylvania scientists whose research breakthroughs laid the foundation for swift vaccine development have been awarded the 2021 Lasker-DeBakey Clinical Medical Research Award. Here, mRNA vaccine pioneers Drew Weissman, MD, PhD, and Katalin Karikó, PhD, share the story behind their development of this groundbreaking technology, and what it means for the future of medicine.
