Episode: The troubling rise of facial recognition technology
Pub date: 2020-11-18

Scientists have grave concerns over ethical and societal impacts of facial-recognition technology. In this surveillance special, we dig into the details.

In this episode:

03:24 Standing up against ‘smart cities’

Cities across the globe are installing thousands of surveillance cameras equipped with facial recognition technology. Although marketed as a way to reduce crime, researchers worry that these systems are ripe for exploitation and are calling for strict regulations on their deployment.

Feature: Resisting the rise of facial recognition

17:44 The ethics of researching facial recognition technology

Despite concerns surrounding consent and use, researchers are still working on facial recognition technology. Can this sort of work be justified? We hear some of the debates going on in academia about this field of research.

Feature: The ethical questions that haunt facial-recognition research

25:02 What do researchers actually think?

Nature surveyed 480 researchers who have published papers on facial recognition, AI and computer science. The results revealed that many researchers think there’s a problem.

Podcast: Voices from DARPA (LS 41 · TOP 2.5% what is this?)
Episode: Episode 34: The Orbital Optician
Pub date: 2020-10-16

 

In this episode of the Voices from DARPA podcast, Stacie Williams, a program manager since 2019 in the agency’s Tactical Technology Office, reveals how a lifelong love of optical and photonic phenomena, beginning with fireflies during her childhood, is now unfolding in her stewardship of ambitious light-and-optics-centric programs at DARPA. One of these, the Deformable Mirror (DeMi) program, recently reached a milestone with the placement from the International Space Station of a dime-sized deformable mirror on a loaf-sized CubeSat platform. The goal of DeMi is to deliver cheaper, lighter, smaller telescope mirrors—in the form of a microelectromechanical system (MEMS)—that could open unprecedented options for space-based ISR (intelligence, surveillance, reconnaissance) technology that, in Stacie’s words, “helps us understand what’s going on with a space eyeview.” In another optics-tech effort under Stacie’s wing, researchers are learning how to design so-called metamaterials—with engineered microstructures that manipulate electromagnetic wavelengths—that also could greatly simplify, lighten, and cheapen far more massive, complex, and expensive conventional telescopes. In the podcast, Stacie also recounts her work beyond technology as a champion of science, technology, engineering, and math (STEM) education for economically disadvantaged communities.

Podcast: The Black Goat (LS 42 · TOP 2% what is this?)
Episode: Talk the Talk
Pub date: 2019-10-30

Academics give a lot of talks. Job talks, conference talks, colloquium talks, brownbag talks, pub talks. In this episode we talk about talks. How do you approach different audiences and formats? How do you manage a format or audience where interrupting with questions is the norm? How, and how much, do you prepare for different kinds of talks? How do you handle nerves when the stakes feel high? We share some of our own observations and experiences about giving academic presentations. Plus: We answer a letter about how “alt-acs” are perceived within academia.

The Black Goat is hosted by Sanjay Srivastava, Alexa Tullett, and Simine Vazire.

Podcast: Big Picture Science (LS 58 · TOP 0.5% what is this?)
Episode: For Good Measure
Pub date: 2019-09-09

The reign of Le Grand K has come to an end. After 130 years, this hunk of metal sitting in a Parisian vault will no longer define the kilogram. The new kilogram mass will be defined by Planck’s constant, joining three other units for redefinition by fundamental constants.  But as we measure with increasing precision – from cesium atomic clocks to gravitational wave detectors able to measure spacetime distortions to 1/1000th the width of a proton – is something fundamental lost along the way?  Meanwhile, the BiPiSci team accepts the banana-measurement challenge.

Guests:

• Jon Pratt – Mechanical engineer and engineer and Chief of the Quantum Measurement Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology
• Wolfgang Ketterle – Physicist at MIT, Nobel Laureate
• Simon Winchester – Author of “The Perfectionists: How Precision Engineers Created the Modern World”

Episode: 42: Productivity and the Color Green
Pub date: 2020-09-08

https://www.usefulscience.org/podcast/42

More people are working from home than ever before. These lifestyle changes can meaningfully impact productivity, stress, and mental health. For example, researchers found that merely thinking that your employer expects you to monitor work email during nonwork hours can ramp up anxiety and harm romantic relationships.

Show Notes

• Pressure to answer work emails during non-work hours negatively affected employees’ health, and decreased the relationship satisfaction of both the employee and their significant other.
• Briefly looking at the color green before working on a creative task (such as coming up with unusual uses for common objects) increased creativity.
