#68 Cyberbiosecurity: Novel Risks in a Connected World - Feras Batarseh | Virginia Tech

Dr. Feras Batarseh is an Associate Professor of Biological Systems Engineering at Virginia Tech. He researches the safety of AI applications, especially in fields like agricultural and drinking water production. Today, he explains the need to consider formerly different types of risks together.   To learn more about Dr. Batarseh's work, visit: https://scholar.google.com/citations?user=oQiAulIAAAAJ&hl=en   P.S. Some fancy words Dr. Batareh used: - Ag and water societies: the decision-makers involved with the agricultural and water treatment sectors. - Cybersecurity: assuring that digital resources (from intangible data to tangible hardware) are able to serve their intended purpose with minimal losses - National security: assuring the wellbeing of the citizens' of a nation in the face of threats, including military, financial, and healthcare disruptions. - Cyber-physical security: preventing unauthorised entry or exit from secured physical facilities, including by protecting the digital equipment and data needed to assure this. - Adversary: a criminal trying to launch cyberattacks. - State vs. non-state adversaries: individual(s) sponsored by governments to launch cyberattacks vs. individual(s) doing so without government aid. - Phishing attacks: pretending to represent a legitimate cause to get confidential data from individual(s). Ex: Getting passwords by pretending to be technical support for a company. - Metaverse: a digitally simulated environment (like in Virtual reality) that lets users mimic the real world by having very diverse/extensive experiences available.

#67 - 'Viral' Vaccines for Bat Viruses - Megan Griffiths | University of Glasgow

Megan Griffiths is a PhD student at the University of Glasgow in Scotland. She researches an innovative tool for public health: self-spreading vaccines in wildlife.
