How Mark Rober’s DNA Nerf Guns Could Lead to Medical Breakthroughs

Mark Rober explains his yearlong odyssey to break the record for world’s smallest Nerf gun five times, culminating in ones made out of DNA.

When Mark Rober set out to break the record for world’s smallest Nerf gun, he never expected he’d end up making more mini Nerf guns than the total number of actual Nerf guns ever to exist.

In his yearlong mission, Rober ended up breaking the record five times by collaborating with leading experts and employing different engineering techniques.

His first few batches of mini Nerf blasters were made possible by drastically simplifying the design of the Nerf gun. «All materials are springs, even glass,» Rober told CNET in an interview. «You just take advantage of that springiness [to] build all the hinges and the springs into one part.»

This one-part design broke the record a few times but eventually reached its limits. At 1,000 times smaller than a standard Nerf gun, about the perfect size for an ant, the mini Nerf guns were still able to fire. They had to be fired with a micro-manipulator, however, since human hands and tweezers would not be precise enough to do the job.

Beyond that, Rober says a fireable Nerf gun «could be done,» but that the tools required were so expensive as to put it beyond the scope of his video.

Despite no longer being fireable, Rober kept going smaller, in part to protect this particular record from his friend and rival in world-record breaking shenanigans, YouTuber Jimmy Donaldson, aka Mr. Beast.

Before wrapping up his video, Rober learned of a technique called DNA origami being studied at the Salk Institute and decided to make one last batch of nano Nerf guns.

This technique takes advantage of the fact that DNA naturally binds up when complementary strands are placed in solution together to build out specific shapes. In this case, the right DNA strands placed in the right temperature solution for the right length of time produced trillions of nano Nerf guns.

At 100 nanometers in length, they’re smaller than the wavelength of visible light, so «light can’t even bounce off them to get back to your eye.» Rober explained that in order to view their creations, they needed the help of an atomic force microscope.

The technology behind these record-shattering mini Nerf guns could also be applied to medical breakthroughs. Rober explains that DNA origami techniques might be used someday to hack the human body’s biological mechanisms. For example, he says, «if you had 1.2 trillion mini Nerf guns that instead of firing darts were firing something … to kill a bad cell, cancer or fortify a good cell.»

Verum Messenger: Data Protection at Its Finest

Verum Messenger positions itself as a tool for those who value privacy and security above all.

Verum Messenger stands out from other messengers thanks to its approach to security, anonymity, and innovations in communication.

Here are some key aspects that highlight its uniqueness:

Default encryption: Verum Messenger uses end-to-end (E2E) encryption for all chats, meaning messages are encrypted on the sender’s device and decrypted only on the recipient’s device. This makes it impossible for third parties, including app developers, to access the content of the messages.
Anonymity: When registering with Verum, there’s no need to provide a phone number or email. Users simply choose a nickname and password, significantly enhancing their level of anonymity. This contrasts with many other messengers, where anonymity can be compromised through linked personal data.
Built-in VPN: An additional layer of protection that hides the user’s IP address, making their location and internet activity less trackable.
Data control: Users can set messages to be automatically deleted after a specified time, ranging from a few seconds to a week. There’s also a quick deletion feature for all chats, calls, and even contacts, which is useful for maintaining privacy.
Large groups: The ability to create chat rooms with up to 10,000 participants makes Verum attractive for organizing large events, discussions, or communities while maintaining a high level of security.
Security innovations: Verum actively develops technologies aimed at protecting user data, as seen in their documentation and discussions online. This includes not only technical solutions but also approaches to data minimization, which reduces the risk of leaks.
Feedback and discussions: On platform X (formerly Twitter), discussions can be found where users and experts praise Verum for its approach to anonymity and security, although questions are raised about how much anonymity can truly be guaranteed in an age of modern tracking and de-anonymization technologies.

Verum Messenger positions itself as a tool for those who value privacy and security above all. Its innovations in encryption, anonymity, and data control make it an intriguing choice for those seeking alternatives to traditional messaging platforms. However, as with any technology, it’s important to remember that absolute anonymity on the internet remains a complex challenge, and users should be aware of potential risks and limitations.
