Throwing Stuff into Space
Burning tons of jet fuel to propel objects out of Earth's atmosphere and into orbit is an expensive, environmentally damage prospect. One company in California is deleoping an alternative. SpinLaunch just completed their 10th test launch, literally throwing satellites thousands of kilometers up into the air. Jeff and Anthony dig into the engineering challenges - and pure audacity - of such an endeavor... and they come away very impressed. [more]

The Long Trail of Mucus
From the slime coating slugs to the saliva in our mouths, many slippery bodily fluids contain mucus. So how did this biological feature evolve? A new study sheds light on a very unexpected origin for mucins in mammals. Jeff and Anthony slide right into the topic, and are surprised how sticky the topic can be. [more]

Mutating Astronaut Blood, A Cautionary Tale
Researchers at NASA have been holding on to astronaut blood for 20 years. But that's not the story. The story is that over that period, the blood has been mutating. Anthony and Jeff discuss this new wrinkle in the dangers of space travel - and space colonization - and how some very smart people are thinking about it. [more]

The Case for Digital Dementia
A new study has found that storing important information in a digital device frees up the mind to remember other, less important details — which otherwise would be crowded out by the important stuff. It suggests that tech might be improving our memories, contrary to the popular notion that tech is giving us all “digital dementia.” Anthony and Jeff discuss whether this data changes their opinions about how devices are impacting human memory, and how new technology can make things even better.

Tongue Vision
Scientists are innovating in the field of Sensory Substitution, using one sense to compensate for an impairment in another. Jeff and Anthony discuss a new study that uses a device called BrainPort to convey visual information to the tongue, in conjunction with audio signals. Could it be an inexpensive alternative to retinal implants? [more]

In the Grip of Necrobotic Spiders
Rice University mechanical engineers are showing how to repurpose deceased spiders as mechanical grippers that can blend into natural environments while picking up objects, like other insects, that outweigh them. Anthony and Jeff discuss the merits of using spider corpses as engineering materials. [more]

Habit Forming and Microwave Friend
How much of our daily lives are lived out of habit? How can habits shape our behavior in positive ways? Anthony and Jeff take a look at new research that suggests habitual action has a much larger role to play in human life than previously thought. Then, how for would you go to talk to your imaginary friend? One Youtuber decided to use some pretty slick technology to do just that, but the results are surprising. Jeff and Anthony step through the story of AI gone frighteningly wrong. [more]

700 Celebration and Face Mites
It's the 700th episode of We Have Concerns and Anthony and Jeff have pulled out absolutely zero stops! Star-studded? Nah. Pomp and circumstance? Eh. Instead, the 700th episode of this award-winning science podcast focuses on new research into the tiny creatures that live on your face. That's right! We all have little monsters living in our face pores, and now we know they have anuses! For pooping! So it looks like the 700th episode is pretty special, after all. [more]

Hibernation Information and Measuring a Second
Can humans reach new planets by hibernating during the trip? A new study on hibernation reveals how the benefits of torpor don't scale with size, and Jeff and Anthony debate the science of human hibernation. Then, what does it take to accurately measure a second? Anthony and Jeff take a look at the effort to redefine the unit of measure that relates to all others. [more]

Revisiting What Concerns Brock Wilbur
In light of the Supreme Court's decision to overturn Roe v Wade, Anthony and Jeff thought it worthwhile to revisit this episode of We Have Concerns from August, 2015. In it, special guest Brock Wilbur relates his experience volunteering at Planned Parenthood. Brock gives a powerful first hand account of the people affected by the court's decision, and Jeff and Anthony are proud to be able to help share Brock's story. Brock Wilbur is a stand-up comic and writer, and the co-host of the Caring into the Void podcast, which you can find anywhere you get podcasts. [more]
