An Alternative To Biliverdin, Mesobiliverdin Ixα And Mesobiliverdin-Enriched Microalgae: A Review On The Production And Applications Of Mesobiliverdin-Related Products, Naveena Poudyal, Jon Y. Takemoto, Yuan-Yu Lin, Cheng-Wei T. Chang

Chemistry and Biochemistry Student Research

Despite attracting interest for decades due to its anti-inflammatory and antioxidant capabilities, the use of biliverdin IXα (BV) in medicine and agriculture is hampered by uncertain purity and limited availability. A significant amount of effort has been devoted to the production and application of BV, but with limited success. Mesobiliverdin IXα (MBV), a natural BV analog derived from microalgae, offers a path to overcome the limitations of BV. MBV production is scalable, and it can be obtained at high purity. MBV and BV share important structural features (e.g., bridging propionate groups) and both are substrates of biliverdin reductase A (BVRA), …

Designing A Cave Air Monitoring System: Guide And Feedback From 15 Years Of Monitoring The Cussac Cave (France), Nicolas Peyraube, Jessica D. Villanueva, Fabien Naessens, Roland Lastennet, Sylvain Mateo, Alain Denis

International Journal of Speleology

Understanding the cave’s ventilation system is important for determining how the cavity interacts with external airflow. This requires a well-designed monitoring system. This article addresses these key aspects: how to build a monitoring system for cave air parameters and how to assess the ventilation of a cave. We proposed a flowchart to help address the issues in: 1) the modularity of a monitoring system, 2) the use of “homemade device” or “ready to use device”, 3) the frequency of measure and its effect on the electrical consumption, 4) the duration of the survey, and 5) the accessibility of the recorded …

Information, Secrecy, And Falsehood, Pierre Le Morvan

Secrecy and Society

Can information be false? An important debate in the philosophy of information turns on this seemingly simple question. According to veridicalism (or the veridicality thesis), truth is a necessary condition for information; by contrast, according to non-veridicalism (or the non-veridicality thesis), it is not. I argue that this debate has noteworthy implications for how we should conceive of secrecy understood in terms of concealment of information. I also argue that, since falsehoods can be secret, it is more tenable to hold that secrecy is not restricted to true information than to hold that it is.

In this keynote address, I describe my personal journey starting with a school outreach program I created in 2017 to address technology overuse among kids. While I initially advocated for self-help methods, I grew to recognize that the tech industry bore responsibility. This realization led me to write Unwired: Gaining Control over Addictive Technologies, which focused on collective action to pressure the tech industry to redesign its addictive products.

I then describe the movement to control addictive technologies and protect kids, which has gained momentum since the end of the pandemic. This movement combines grassroots parent activism with legal-political action. …

Moral Panic Or Public Health Crisis? Lessons From Drugs And Gambling For “Addictive” Design, Matthew B. Lawrence, Haomin (Kevin) Yan

Seattle University Law Review

Alcohol, automobiles, guns, lottery, loot boxes, meat, music, opioid painkillers, processed foods, prop bets, slot machines, television, tobacco, violent video games. Over the last century each of these has been subject to concerns—some might even say “moral panics”—from parents and policymakers about avoidable harms to kids and adults. In some cases we look back with the benefit of hindsight and dismiss those concerns as naïve or moralistic. In others we look back at them as justified or as having come too late to check an expanding industry before it did unfathomable harm while growing so powerful that it became all …

Responding To Digital Addiction, Ned Snow

Seattle University Law Review

In Unwired: Gaining Control over Addictive Technologies, Professor Gaia Bernstein calls our attention to the growing problem of digital addiction. Digital addiction may sound like something out of a science-fiction novel or something that does not raise the same sort of real-life practical concerns as are present in a physical health crisis or an economic decline. But as Bernstein presents the evidence, we learn that the consequences of digital addiction can be just as harmful as a serious disease or a financial depression. Cognitive development disorders, anxiety, emotional depression, social isolation, and other mental health ills can be debilitating—as much …
