A new weapon in the fight against superbugs | David Brenner

TL;DR

In this talk, physicist David Brenner discusses his personal war on superbugs and introduces the concept of using safe, far-UVC light to kill bacteria.

Transcript

So ... we're in a real live war at the moment, and it's a war that we're truly losing. It's a war on superbugs. So you might wonder, if I'm going to talk about superbugs, why I'm showing you a photograph of some soccer fans -- Liverpool soccer fans celebrating a famous victory in Istanbul, a decade ago. In the back, in the red shirt, well, that's m... Read More

Key Insights

• 🦠 Superbugs, drug-resistant bacteria for which we don't have effective drugs, are a growing problem and responsible for 700,000 deaths last year and an estimated 10 million deaths by the middle of this century.
• 🌡️ Ultraviolet (UV) light can kill bacteria, including superbugs, by a different mechanism from drugs, but conventional UV light is a health hazard that cannot be used around people.
• 🔬 Far-UVC light, a specific wavelength of UV light, can kill bacteria, including superbugs, without penetrating the skin or causing damage to cells, making it safe for human exposure.
• 🧪 Research has shown that far-UVC light is both effective at killing bacteria and safe for human exposure, making it a promising tool in the fight against superbugs.
• 🏥 Far-UVC lights can be used in surgical theaters, food preparation areas, schools, airports, and airplanes to prevent the spread of bacteria and viruses like the flu and measles.
• 🌍 The development and widespread use of far-UVC lights can contribute to a major advance in the war against superbugs and have a significant impact on public health worldwide.
• 💡 The main obstacles to rolling out far-UVC light technology are conducting safety tests, obtaining FDA approval, and overcoming skepticism among biologists and doctors about the safety of UV light.
• 🌏 The goal is to launch far-UVC light technology in both the US and Japan, and data from research studies will be the foundation for convincing skeptics and gaining regulatory approval.

Questions & Answers

Q: What is the main problem discussed in the video?

The main problem discussed in the video is the war on superbugs, which the speaker describes as a war that we are currently losing.

Q: How did the speaker become involved in the war on superbugs?

The speaker became involved in the war on superbugs after a close friend of his died from a superbug-related infection following minor surgery. This personal tragedy prompted him to declare his own war on superbugs.

Q: What are superbugs?

Superbugs are bacteria for which we do not have effective drugs. They are drug-resistant bacteria that have emerged due to the overuse and misuse of antibiotics over the years.

Q: How does ultraviolet light play a role in fighting superbugs?

Ultraviolet light, particularly far-UVC light, has the potential to kill bacteria, including superbugs, without harming human cells. This different approach to killing bacteria could be a powerful weapon in the fight against superbugs.

Q: Is far-UVC light safe for human exposure?

Yes, far-UVC light has been determined to be safe for human exposure. It is strongly absorbed by biological materials, such as the skin, and therefore cannot penetrate into human cells. This makes it an ideal option for sterilization in the presence of people.

Summary & Key Takeaways

• Superbugs, drug-resistant bacteria for which we don't have effective drugs, are a global threat and caused around 700,000 deaths from related diseases last year.

• Conventional germicidal ultraviolet (UV) light is effective at killing bacteria, but also harmful to humans.

• Far-UVC light, a particular wavelength of UV light, can kill bacteria including superbugs, but is safe for human exposure. Research is ongoing to ensure its safety and gain regulatory approval.
