We know that science is constantly evolving behind the scenes, though most of us have no idea how far it has advanced in the past few years. Many technologies once considered "futuristic" and existing only in the realm of science fiction are now reality—from invisibility cloaks to mind-controlled prosthetics and advanced autonomous weapons.
10. Realistic holograms
Holograms have long been used in the form of holographic paper—a printing technique that uses light waves to create a three-dimensional image. They are most often used as an anti-counterfeiting measure for items such as banknotes, tickets, ID cards, and product tags, among others.
However, holograms have recently taken on a much more sophisticated form thanks to innovations in fields like augmented and virtual reality. Technologies like MIT's Tensor Holography can now use artificial intelligence and machine learning to create truly realistic holograms, which can, in turn, be interacted with in a variety of ways to make them more immersive.
Once hologram technology is fully realized, it could be used for a wide variety of purposes. Imagine being able to conduct a fully holographic conference call with participants located in completely different locations around the world. It could also be used to monitor remote objects in hazardous locations, such as offshore drilling rigs, significantly reducing the risks associated with the work. .
9. Nanorobots
Nanobots, also known as nanorobots or nanomachines, have been a staple of science fiction for as long as we can remember. Capable of performing complex tasks at the cellular or molecular level, these microscopic machines have been imagined as tiny medical assistants, self-replicating repair machines, and deadly weapons. In real life, however, until recently, nanobot technology has always been something of the distant future.
Over the past few years, numerous teams working in the field around the world have made significant advances in various applications. In 2018, researchers in Hong Kong successfully developed bots capable of targeting tumors at the cellular level. These were essentially reprogrammed DNA strands loaded with chemotherapy drugs specifically designed to seek out and destroy tumors that could one day develop into cancer.
In January 2020, another team of researchers from Tufts University went even further and developed the first-ever living nanorobots. Created from stem cells taken from frogs, these tiny machines, also called xenobots, can move, heal themselves, and even assemble together to create new bots on their own.
8. Deadly autonomous robots
Lethal autonomous robots are a general term for weapons that can operate without human intervention. Using technologies like artificial intelligence and advanced remote sensors, these future weapons could be programmed to make targeting decisions entirely independently, completely bypassing the need for soldiers on the ground.
Unfortunately, weapons with autonomous capabilities have already begun to appear on battlefields around the world. Both Russia and Ukraine have deployed autonomous weapons in their ongoing wars, and a UN report claims that Turkey used its Kargu-2 autonomous drones to track Libyan soldiers during the Libyan civil war. Currently, nearly every major military power is working on its own lethal autonomous weapons, despite strong opposition from human rights groups and scientists seeking to curb this technology.
7. Thought-controlled prosthetics
Prosthetics that can be instinctively controlled by the brain have only been imagined in science fiction, although several breakthroughs in recent years may make them a reality sooner than we think.
Ongoing research at the University of Michigan is responsible for many of these breakthroughs. In 2020, researchers at the university developed a method for amplifying weak signals from amputated nerves to control a robotic arm in real time, allowing intuitive fingertip control of the prosthetic. The approach involves tiny muscle grafts, machine learning algorithms, and electrodes implanted in areas of the brain that control movement and process the sense of touch of the natural limb. Building on this research, another team from the same university developed the so-called regenerative peripheral nerve interface (RPNI)—a small muscle grafted onto the end of a severed nerve.
6. Invisibility cloak
Real invisibility cloaks have been used in all sorts of fictional settings, perhaps because they provide a simple mechanic for moving the story in a specific direction. If they were invented, many types of weapons systems would become obsolete, especially those that rely on visual confirmation.
In 2019, the Canadian company Hyperstealth Biotechnology, which specializes in military camouflage, unveiled its own concept—a material they called Quantum Stealth. Unlike other early invisibility cloak prototypes used to date, this material bends light around itself to make an object appear invisible to the naked eye, and it even works with infrared and ultraviolet imagers. It is primarily intended for military use, as the material can be used as a camouflage layer for combat equipment, making it virtually impossible to target from the air.
5. Dream reading
Dream reading isn't something you think scientists can do, at least not in the way most of us imagine. Of course, you're wrong, as there have already been significant breakthroughs in this field. Today, it's possible not only to see and hear—with reasonable accuracy—the content of other people's dreams, but also to reshape them to reflect a specific theme.
In a breakthrough study from Japan published in the journal Science , They discovered a method for using MRI scans to map images of a subject's sleep with 60% accuracy. In another study, researchers from MIT developed a device called Dormio that can broadcast specific sound cues just before you fall asleep and alter the content of your dreams.
4. See through walls
The Xaver 1000 is a portable scanner developed by Camero-Tech, a military technology firm based in Israel. It's actually an imaging device that uses artificial intelligence and sophisticated image processing techniques, such as its proprietary "Sense-Through-The-Wall" technology, to detect people and animals behind obstacles like walls.
The scanner is useful in a wide variety of situations, particularly hostage situations that require thorough mapping of the scene before any law enforcement action. The device also has numerous military applications, as it is extremely useful in confined spaces, such as urban areas and densely populated areas. It can also be useful for saving lives during natural disasters or other calamities.
Self-healing materials are another major innovation that will revolutionize prosthetics, although that's not their only application. As the name suggests, researchers have made many breakthroughs in this field in the past few years, and we may be very close to developing a truly self-healing material that can mimic organic materials like skin.
In 2008, researchers from PSL University in France developed a synthetic rubber that can retain and restore its properties even after repeated degradation. Building on this concept, chemical engineers at Stanford University developed a polymer that can regenerate even after being completely severed with a scalpel, while maintaining its original properties. The best part is that it can be recycled over and over again, something previously unattainable in the laboratory.
2. Mind reading technology
Reading dreams is one thing, but what about reading the active, waking brain? Mind-reading technologies could find military applications, such as mind control, or even be used by large corporations for targeted advertising. On the other hand, the ability to read minds has many potential applications in medicine, especially in cases where the patient is unable to communicate due to injury or illness.
Surprisingly, this isn't that far in the future, as we already have many technologies that can, to some extent, digitally reproduce the internal contents of your head. In an article published in Nature magazine In 2022, researchers from Radboud University in the Netherlands developed a method for converting brainwaves into photographs. They took fMRI scans of subjects and fed the results to an AI algorithm, which was then able to reproduce them on a screen almost identically. .
1. Reverse aging
Aging is a problem that has plagued humanity for quite some time. Most people agree that it's an unnecessary function that causes problems and, ultimately, death, yet even our best scientists and doctors have been unable to find a cure for it for centuries.
Currently, we don't have the technology to do this for humans, although it's possible for rats. In a 13-year study led by Dr. David Sinclair, a professor at the Center for the Biological Study of Aging at Harvard Medical School, researchers were able to reverse or accelerate the aging process in mice. In his research, Sinclair discovered that aging occurs due to the loss of critical information in the genetic makeup of our cells, not just the damage accumulated over the years.
His team demonstrated this in their experiments, where they successfully restored the epigenetic information stored in cells to either return mice to an earlier, younger state—with restored vision and younger muscles—or prematurely accelerate their aging process.
