The metaverse, the latest buzzword in the tech world, has been met with a mix of excitement and skepticism. While some envision a futuristic realm that will revolutionize the internet, others dismiss it as a vague and unwanted concept. However, according to assistant professor Diego Gómez-Zará from the University of Notre Dame, the metaverse has the potential to enhance scientific research and make scientists more effective. In his article, "The Promise and Pitfalls of the Metaverse for Science," Gómez-Zará highlights the benefits of virtual reality and urges researchers to consider its possibilities.

One advantage is the removal of barriers, making science more accessible. Gómez-Zará cites examples where scientists have already utilized virtual environments, such as a digital replica of a lab at the University College London School of Pharmacy. This virtual space allows researchers from different locations to collaborate effectively, overcoming geographical limitations. Furthermore, virtual reality can facilitate teaching and learning by providing a safe environment for trainees to practice procedures without risking harm to real patients. (Read more here)

The social side of science can also benefit from the metaverse. Gómez-Zará's team at Notre Dame's Virtual Reality Lab found that virtual environments foster better collaboration among teams compared to videoconferencing. Moreover, the metaverse can create entirely new experimental settings by replicating real-world environments virtually. For instance, scientists could explore Mars through virtual reality, interacting with the environment and gathering data without the need for physical presence.

However, Gómez-Zará acknowledges the potential pitfalls of the metaverse. Barriers to entry, such as the cost of virtual reality equipment, still exist. Additionally, concerns surrounding ownership and privacy need to be addressed. Currently, a few technology companies control the metaverse, but calls for an open and public metaverse have emerged.

Despite these challenges, Gómez-Zará remains optimistic and encourages the research community to explore the possibilities of the metaverse. Just as we swiftly adapted to new technologies during the pandemic, he believes that embracing the metaverse could lead to innovative breakthroughs in science. By planning for the risks and recognizing the vast possibilities, scientists can leverage virtual reality to enhance their work and propel research into the future.

👨‍⚕️ Tiny Robots to the Rescue

Meet the Speedy Microrobots that Could Help Medicine

In a groundbreaking development, engineers at the University of Colorado Boulder have introduced a new class of "microrobots" that could potentially revolutionize medical treatments. These tiny robots, smaller than the width of a human hair, have the potential to treat various human illnesses, including interstitial cystitis—a bladder disease that affects millions of Americans.

Lead author Jin Lee, a postdoctoral researcher in the Department of Chemical and Biological Engineering, envisions a future where these microrobots can perform non-invasive surgeries within the body. Instead of invasive procedures, these robots could be introduced through a pill or injection, undertaking the necessary tasks autonomously. While this vision is still a long way off, the recent research marks a significant step forward in the field of tiny robots.

These microrobots are not only minuscule but also remarkably fast, traveling at speeds of about 3 millimeters per second, or roughly 9,000 times their own length per minute. The researchers conducted experiments using fleets of these robots to transport doses of a common steroid medication, dexamethasone, to the bladders of lab mice. The successful results suggest that microrobots could be instrumental in treating bladder diseases and other illnesses in humans.

While this scientific breakthrough is undeniably exciting, it also evokes memories of the classic film Fantastic Voyage, where a submarine is shrunk and navigates the human body. Lee acknowledges the resemblance, highlighting the technological progress made since the movie's release in 1966. He envisions microrobots navigating the bloodstream, targeting specific areas for treatment—a concept that was once confined to science fiction but is now becoming a reality.

The microrobots are made from biocompatible polymers, resembling small rockets with three tiny fins. They are equipped with trapped air bubbles, which, when exposed to an acoustic field, vibrate wildly, propelling the robots forward. The team is working on making the robots fully biodegradable, allowing them to dissolve in the body after use. (Read more here)

The initial focus of the research was on bladder disease, specifically interstitial cystitis. By encapsulating high concentrations of dexamethasone, the researchers successfully dispersed the microrobots throughout the bladders of lab mice. The robots adhered to the bladder walls, releasing the medication gradually over a period of two days. This sustained drug release could lead to improved outcomes for patients, reducing the frequency of clinic visits and providing a more effective treatment option.

While there is still much work to be done before microrobots become a reality in human bodies, the potential they hold for transforming medical treatments is awe-inspiring. The ability to perform non-invasive procedures and provide targeted treatments could revolutionize healthcare, improving the lives of millions of people. So, perhaps in the not-too-distant future, these tiny robots will indeed be zipping through our bodies, fixing what ails us, and proving that size doesn't matter when it comes to medical marvels.
