Main Discussion Points & Insights

1. Public Health Surveillance at the World Cup (01:04–03:32)

• With over 5 million international visitors expected at the World Cup in North America, public health agencies are preparing for possible outbreaks.
• Lauren Young (Associate Editor, Health and Medicine):
  • Cities are ramping up wastewater surveillance systems to detect genetic material from viruses shed in human waste (e.g., via skin, saliva).
  • This system, led by Georgetown University and MedStar Health, can identify a wide range of pathogens:
    • COVID-19, measles, influenza, and even insect-borne illnesses like chikungunya and dengue.
    • Real-time genomic sequencing and dashboards help officials rapidly respond to outbreaks.
    • Focus is higher on diseases like measles and influenza than on Ebola, despite the latter’s ongoing outbreak globally.
• Notable Quote:
  • "Wastewater is like a super helpful forecast tool, if you will, to pick up things like genetic material from viruses that people might shed into waste via their skin or saliva, things like that."
    — Lauren Young [02:24]
  • "The Wastewater Surveillance Network does have the capability of detecting [Ebola]…but team members that I spoke to say that they're not as concerned about Ebola spread in the US right now in comparison to things like measles or influenza."
    — Lauren Young [03:18]
• Follow-up coverage is promised on scientificamerican.com.

2. NASA’s MAVEN Mars Mission Ends (03:32–04:48)

• NASA officially decommissions the MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft after losing contact six months ago.
  • MAVEN launched in 2013, entered Martian orbit in 2014, and exceeded its initial one-year mission.
  • Contributions:
    • Advanced understanding of Mars’ upper atmosphere and its interaction with the sun.
    • Supported communications for both NASA and European Space Agency rovers on Mars.
• Rachel Feltman’s Reflection:
  • "While Maven's demise is a shame and came without warning, the orbiter certainly outlived its initial mission length, which was just one year."
    — Rachel Feltman [04:32]

3. Shifting U.S. AI Regulation Policy (04:48–05:34)

• President Donald Trump issues an executive order requiring tech companies to provide government access to advanced AI models for up to 30 days prior to public release.
  • Originally proposed as a 90-day review period, shortened after industry feedback.
  • Goals include enhancing U.S. cybersecurity defenses and improving competitiveness against China in AI.
• Rachel Feltman’s Summary:
  • "The order tasks federal agencies with improving U.S. defenses against cybersecurity threats, and it asks AI companies to provide access to their models for up to 30 days before public release."

4. Mapping Ancient Roman Roads — High-Tech Archaeology (05:34–07:30)

• Andrea Garleski (Newsletter Editor):
  • Researchers created a high-resolution map of Roman roads—300,000 kilometers, more than double earlier estimates.
  • The mapping combined:
    • Ancient milestone data (over 8,000 recorded)
    • Databases of ancient places (about 14,000)
    • Declassified Cold War satellite imagery
    • Military topographic maps for challenging terrains
    • Geological analysis to match roads to ancient landscapes
  • Many roads remain invisible today due to urbanization or environmental changes.
  • Resource: The new map/atlas is publicly viewable at ITINERE.org.
• Memorable Moment:
  • "The Romans themselves did not invent roads, but boy did they know how to scale up a good thing."
    — Andrea Garleski [07:13]
  • "All this helped them create a stunning high res map of roads of the Roman Empire."
    — Andrea Garleski [07:04]

Happy Monday listeners, and happy pride for Scientific American Science Quickly. I'm Rachel Feltman. You're listening to our weekly science news roundup. The World cup kicks off in just a few days. Now, I love the beautiful game as much as the next guy, but I will say that this international spectacle is already messing with my commute, which I don't appreciate. But my concerns about overcrowded public transit are small potatoes compared to what public health experts have to worry about in the wake of such a large event. New York City's health commissioner recently told NPR that the city has been running simulations to prepare for mass casualty events and disease outbreaks. And some of the World cup locations in the US Are also dialing up their use of wastewater surveillance to catch any pathogens. Here to tell us more about that is Lauren Young, associate editor for Health and Medicine at Scientific American. Thanks for being here, Lauren.

[Lauren Young]

Thanks, Rachel. So more than 5 million people from around the world are going to be traveling to North America for the World cup this week. 16 different cities are going to be hosting the games. But as people come, public health experts are going to be on pretty high alert for any potential outbreaks of infectious diseases. And and the way they're doing that is using this forecasting system through wastewater detection. Wastewater is like a super helpful forecast tool, if you will, to pick up things like genetic material from viruses that people might shed into waste via their skin or saliva, things like that. So this surveillance is being led by Georgetown University and MedStar Health, who are assembling various different partners around the US to be monitoring wastewater. The wastewater surveillance system is going to be able to detect things like Covid measles and influenza that scientists are also looking out for things like insect borne illnesses such as chikungunya and dengue. A genomics team will also be sequencing viruses to further trace any potential outbreaks, so the network will have real time dashboards to disseminate information quickly to the public as well as public health officials to take any necessary actions on containing outbreaks. I'm personally keeping tabs on the ongoing outbreak of Ebola and how concerned scientists are about cases emerging in North America as people travel for the games. The Wastewater Surveillance Network does have the capability of detecting the virus, but team members that I spoke to say that they're not as concerned about Ebola spread in the US Right now in comparison to things like measles or influenza.

Thanks again Lauren Listeners, we'll be sharing some more World cup related stories both here and on scientificamerican.com, so stay tuned now for some bittersweet space news. Six months ago, NASA lost contact with the Mars Atmosphere and Volatile Evolution mission, known as Maven for short. Last Wednesday, a statement from NASA confirmed that the orbiter is lost for good. Maven launched back in 2013 and entered Martian orbit in September of 2014. Since then, the orbiter helped scientists understand the upper atmosphere of Mars, its ionosphere, and the way it interacts with the sun. Maven also helped form the communication network that keeps both NASA and the European Space Agency in contact with their rovers on the Martian surface. While Maven's demise is a shame and came without warning, the orbiter certainly outlived its initial mission length, which was just one year. Let's move on to a story about artificial intelligence. Last Tuesday, President Donald Trump issued an executive order that asks Congress companies to grant the government early access to advanced AI models. The order tasks federal agencies with improving U.S. defenses against cybersecurity threats, and it asks AI companies to provide access to their models for up to 30 days before public release. To facilitate this, Trump was originally slated to sign a version of the executive order on May 21, but he told reporters that day that he was pulling it out of concern that it could make the US Less competitive against China Chinese AI. CNN reports that the late May version of the order actually called for a 90 day review period, but that after conversations with tech companies, this was shortened. Our last story comes from SIAM's chief newsletter editor, Andrea Garleski. She's here to tell us about some groundbreaking new research on the roads that paved the way for the Roman Empire's success. Take it away Andrea.

[Andrea Garleski]

Thanks Rachel. Researchers created a high resolution map of some 300,000 km of roads in ancient Rome. This more than doubles the previous estimate of roads in the Empire. The roads span an area the size of the EU that stretches from Egypt to Germany and Spain to Turkey. So how did they do this? Archaeologists combined a bunch of different sorts of data to make their map. First of all, they looked at milestone rocks. The Romans placed these stone pillars every 1000 paces along the roads. They were like ancient mileage signs and were engraved with how far you were from Rome and also some details about the local government. So the team aggregated the databases that included more than 8,000 milestones, around 14,000 ancient places, and then started connecting the dots between them. But some roads are not visible anymore, like some ancient cities have flooded over the centuries or have been built over by urbanization. So the researchers examined declassified photos from Cold War era satellites to reconstruct what shape these roads took and what else. The team looked at detailed topographic maps that were mostly made for military strategy, which gave them detailed data about the topography of the roads along mountains or other landscapes. And lastly, the researchers evaluated the land itself. Certain areas of the currently accepted version of the roads don't match the landscape and simply would not be possible today. So the team studied sediments to reconstruct the ancient landscape and find the dry lands that once could have supported roads. All this helped them create a stunning high res map of roads of the Roman Empire. The Romans themselves did not invent roads, but boy did they know how to scale up a good thing.
