Top Lectures: ‘A Series Of Fortunate Events’ By Biologist Sean B. Carroll

Is simple chance the source of all the beauty and diversity we see in the world? Sean B. Carroll tells the story of the awesome power of chance. Sean’s book “A Series of Fortunate Events” is available now: https://geni.us/mPPrdQH

Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance.

Sean B. Carroll is an award-winning scientist, writer, educator, and film producer. He is Vice President for Science Education at the Howard Hughes Medical Institute and the Balo-Simon Chair of Biology at the University of Maryland. His books include The Serengeti Rules (Princeton), Brave Genius, and Remarkable Creatures, which was a finalist for the National Book Award. He lives in Chevy Chase, Maryland. This talk and Q&A was recorded by the Royal Institution on 6 October 2020.

Science: Pandemic Video Game, Giant Pandas & Top Ten 2020 Stories (Podcast)

A video game provides players with insights into pandemic responses, giant pandas and our annual festive fun.

In this episode:

01:02 Balancing responses in a video game pandemic

In the strategy video-game Plague Inc: The Cure, players assume the role of an omnipotent global health agency trying to tackle outbreaks of increasingly nasty pathogens. We find out how the game was developed, and how it might help change public perception of pandemic responses.

10:02 “We three Spacecraft travel to Mars”

The first of our festive songs, we head back to July this year, and the launch of three separate space missions to the red planet. Scroll to the transcript section at the bottom of the page for the lyrics.

12:54 Research Highlights

Giant pandas roll in piles of poo to keep warm, and how different bread-baking styles have led to distinct lineages of baker’s yeast.

15:17 The Nature Podcast Audio Charades Competition: Lockdown edition

In this year’s festive competition, our reporters try to describe some of the biggest science stories, using only homemade sound effects. Results are mixed, at best…

24:15 Nature’s 10

We hear about some of the people who made it on to this year’s Nature’s 10 list this year.

32:20 All I want for Christmas is vaccines

In our final festive song, we celebrate a huge scientific achievement, and one that’s offering a little hope for 2021. Scroll to the transcript section at the bottom of the page for the lyrics.

Science: Researchers Build Crash-Resistant Flying ‘Beetlebot’ (Video)

Beetles are virtually crash resistant. Their wings fold up when they collide with objects, and then quickly spring back into place. That helps the insects stay on course and fly straight, rather than spiral to the ground, while exerting little energy. Researchers have now built a winged robot that mimics this capability.

The “beetlebot” keeps flying, even after it crashes into poles, researchers report this month in Science. The energy-efficient robot could even navigate narrow environments, such as collapsed buildings, to aid rescue missions, the team says.

Science Podcast: Ecology Study Replication, Return Of The Tasmanian Devil

The field of psychology underwent a replication crisis and saw a sea change in scientific and publishing practices, could ecology be next? News Intern Cathleen O’Grady joins host Sarah Crespi to talk about the launch of a new society for ecologists looking to make the field more rigorous.

Sarah also talks with Andrew Storfer, a professor in the School of Biological Sciences at Washington State University, Pullman, about the fate of the Tasmanian devil. Since the end of the last century, these carnivorous marsupials have been decimated by a transmissible facial tumor. Now, it looks like—despite many predictions of extinction—the devils may be turning a corner. 

Science Podcast: Shallow Pool Origins For Life On Earth, ‘Covidization’

How water chemistry is shifting researchers’ thoughts on where life might have arisen, and a new model to tackle climate change equitably and economically.

In this episode:

00:46 A shallow start to life on Earth?

It’s long been thought that life on Earth first appeared in the oceans. However, the chemical complexities involved in creating biopolymers in water has led some scientists to speculate that shallow pools on land were actually the most likely location for early life.

07:44 Coronapod

The COVID-19 pandemic has massively shifted the scientific landscape, changing research and funding priorities across the world. While this shift was necessary for the development of things like vaccines, there are concerns that the ‘covidization’ of research could have long-term impacts on other areas of research.

News: Scientists fear that ‘covidization’ is distorting research

20:45 Research Highlights

The Hayabusa2 mission successfully delivers a tiny cargo of asteroid material back to Earth, and a team in China claims to have made the first definitive demonstration of computational ‘quantum advantage’.

22:38 Calculating carbon

Limiting carbon emissions is essential to tackling climate change. However, working out how to do this in a way that is fair to nations worldwide is notoriously difficult. Now, researchers have developed a model that gives some surprising insights in how to equitably limit carbon.

29:08 Briefing Chat

We discuss some highlights from the Nature Briefing. This time, bioluminescent Australian animals, and the collapse of the Arecibo telescope.

Future Science: ‘Artificial Intelligence Everywhere’

December 4, 2020

Imagine a robot trained to think, respond, and behave using you as a model. Now imagine it assuming one of your roles in life, at home or perhaps at work. Would you trust it to do the right thing in a morally fraught situation?

That’s a question worth pondering as artificial intelligence increasingly becomes part of our everyday lives, from helping us navigate city streets to selecting a movie or song we might enjoy — services that have gotten more use in this era of social distancing. It’s playing an even larger cultural role with its use in systems for elections, policing, and health care.

Science Podcast: Covid-19 Vaccine Review And Side Effects, Restoring Vision

Staff Writer Meredith Wadman and host Sarah Crespi discuss what to expect from the two messenger RNA–based vaccines against COVID-19 that have recently released encouraging results from their phase III trials and the short-term side effects some recipients might see on the day of injection.

Sarah also talks with researcher Xing Chen, a project co-leader and postdoctoral scientist at the Netherlands Institute for Neuroscience, about using brain stimulation to restore vision. Researchers have known for about 70 years that electrical stimulation at certain points in the brain can lead to the appearance of a phosphene—a spot of light that appears not because there’s light there, but because of some other stimulation, like pressing on the eyeball. If electrical stimulation can make a little light appear, how about many lights? Can we think about phosphenes as pixels and draw a picture for the brain? How about a moving picture?
