Turning Dragonflies into Drones: The DragonflEye Project

What is the DragonflEye Project?

The DragonflEye project is a research initiative that aims to transform live dragonflies into hybrid drones. By equipping these insects with miniature backpacks containing navigation systems, scientists can remotely control their flight patterns.

How Does it Work?

The backpacks contain tiny solar panels to power the navigation systems. These systems tap directly into the dragonflies’ nervous systems, allowing researchers to steer the insects in specific directions using pulses of light.

Why Dragonflies?

Dragonflies are ideal candidates for drone conversion due to their exceptional flight capabilities. They can fly long distances, hover, and even fly backwards, making them highly maneuverable.

Potential Applications

Dragonfly drones have a wide range of potential applications, including:

  • Remote environment monitoring: They can be used to collect data in hazardous or inaccessible areas.
  • Search and rescue: They can assist in locating survivors in collapsed buildings or other disaster zones.
  • Crop pollination: They could be used to steer honeybees and other pollinators to pollinate specific areas, helping to save crops.
  • Surveillance: Their small size and ability to blend in make them ideal for covert surveillance operations.

Benefits of Backpack-Wearing Dragonflies

The backpacks affect the dragonflies minimally, allowing them to continue their natural behaviors and flight mechanics. This means they can still hunt for food as usual.

Future Developments

Researchers are currently focused on establishing basic navigation and control mechanisms for the DragonflEye platform. Once this foundation is in place, they plan to explore larger-scale applications.

Ethical Considerations

While the DragonflEye technology has great potential, it also raises ethical concerns. Researchers must carefully consider the implications of using insects for surveillance or other potentially harmful purposes.

Beyond Dragonflies

The technology developed for the DragonflEye project could potentially be adapted to other insects, such as honeybees. This could help address the decline in honeybee populations and support their vital role as pollinators.

Conclusion

The DragonflEye project represents a groundbreaking advance in the field of insect-based technology. By harnessing the natural flight capabilities of dragonflies, scientists are opening up new possibilities for remote sensing, surveillance, and environmental monitoring.

CDC Ends Community-Level COVID-19 Tracking: What to Know

CDC Ends Community-Level COVID-19 Tracking

Background

The Centers for Disease Control and Prevention (CDC) has announced that it will soon stop tracking the spread of COVID-19 at the community level. This decision comes as the nationwide public health emergency declared in January 2020 is set to expire on May 11.

Impact of Ending Public Health Emergency

The end of the public health emergency will have several implications:

  • The price of some COVID-19 treatments could increase.
  • Vaccines and at-home tests might not be free for as many people.
  • Labs will no longer be required to report COVID-19 testing data to the federal government.

CDC’s New Monitoring Approach

With the end of the public health emergency, the CDC will no longer have access to the same data it currently uses to track community levels of COVID-19. As a result, the agency will update its measure for conveying risk based on data that will still be available.

The CDC will continue to monitor cases of the virus through:

  • Hospitalizations: This indicator provides a delayed notice about an increase in cases compared to test data, as people can test positive and be contagious before being hospitalized.
  • Wastewater testing: This method can detect the presence of the virus even when people are not experiencing symptoms or seeking testing.

Current COVID-19 Situation in the US

Currently, the US is averaging:

  • Over 1,000 deaths per week
  • Over 1,500 hospitalizations per day
  • Around 88,000 reported cases per week

While deaths have fallen since the beginning of the year, around 7.5% of adults in the US are experiencing long COVID symptoms. Additionally, only 16.7% of the US population has received an updated bivalent booster.

Implications for Reporting and Surveillance

After the public health emergency ends, doctors will still have to report COVID-19 cases to health officials. However, the frequency of reporting could drop significantly, with some states reporting as sparingly as once per month.

This reduced reporting frequency may result in less timely data on the spread of the virus. However, the CDC is working to mitigate this by developing new surveillance methods that rely on data that will still be available.

Community Level Tracker Replaced

The CDC’s current community level tracker, which uses hospitalizations and case numbers to determine spread, replaced a previous one that used infection rates and percentage of positive tests. This change resulted in many communities previously considered high risk being reclassified as medium or low risk. As of April 13, 2023, 97% of counties, districts, and territories were considered to have a low level of spread.

Conclusion

The CDC’s decision to stop tracking community levels of COVID-19 reflects the evolving nature of the pandemic and the need to adjust surveillance methods as the virus becomes more endemic. While the end of the public health emergency may bring some challenges, the CDC is committed to providing the information necessary to protect public health.
