What does tomorrow look like? It’s being engineered today, from robot-assembled homes to augmented realities that blur the lines between the physical and virtual worlds.

Space Exploration Faces Cost Challenges But Innovations Offer New Hope

Progress in space exploration has stalled since the 1960s, largely because of the high cost of getting to space. Rockets, the traditional tool for reaching orbit, require vast amounts of expensive fuel and carry significant risks. To address this, scientists are exploring novel methods like creating more affordable reusable transportation.

Among the proposed concepts is the space elevator, which would consist of a cable strung between Earth and a high-altitude station anchored to an asteroid. This would drastically reduce costs and eliminate the need for fuel-heavy rockets. Unfortunately, we lack materials light and strong enough to build this. Engineers are also working on spaceplanes, which could use hybrid engines combining fuel with air for propulsion, reducing the need for oxidizers.

Another avenue is asteroid mining, where resources like water, metals, and oxygen could be extracted. Companies like Tethers Unlimited are testing systems like "the Wrangler," a space net designed to capture and manipulate asteroids. Harnessing these techniques could make space settlements and resources more viable and economical.

Examples

  • The 1969 Moon landing cost around $25 billion, underscoring the expense of manned missions.
  • The "Wrangler" system proposes using asteroids as resource hubs for future space ventures.
  • Spaceplane technologies combine standard and rocket propulsion systems to reduce costs.

Fusion Power Might Finally Transform Energy Consumption

Fusion—the process of atoms combining—promises cleaner, safer, and more abundant energy than fission, which splits atoms. But creating controlled, energy-positive fusion reactions has proven elusive since the energy needed to initiate fusion often exceeds the output.

Organizations like Sandia Labs are advancing fusion through projects like the MagLIF experiment. Using the Z machine, a powerful generator, they compress plasma to release bursts of fusion energy. Efforts like ITER, an international collaboration, aim to create sustained fusion in donut-shaped chambers using magnetic fields to heat plasma.

Breakthroughs in this field could revolutionize energy by eliminating fossil fuels and drastically lowering greenhouse gas emissions. But delays in research and budget issues have hampered progress. Still, optimism remains with experimental reactors aiming to generate energy as early as the mid-2020s.

Examples

  • The Z machine releases bursts of fusion energy, albeit inefficiently.
  • ITER involves contributions from 35 countries to build a functional reactor.
  • Fusion also avoids long-lasting nuclear waste, a drawback of traditional fission power.

Programmable Matter: Science Fiction Turned Real

Imagine a world where materials could alter their shapes or functions on demand. This concept of programmable matter is becoming a reality, with applications varying from healthcare to construction. What's impressive is the ability to reconfigure objects dynamically for specific uses.

Dr. Daniela Rus at MIT leads advancements in origami robots, small programmable devices that fold and maneuver expertly through the human body to deliver medicine where needed. Another example includes materials like HygroScope wood, which adjusts its shape based on humidity, opening myriad possibilities for adaptive buildings.

However, programmable matter raises ethical challenges. The idea of a "Bucket of Stuff"—programmable goo that could morph into anything—could lead to dangerous items like weapons. This forces society to weigh the benefits of innovation against potential risks.

Examples

  • Origami robots made from pig intestines perform tasks inside human bodies.
  • HygroScope timber design adapts to moisture levels.
  • The "Bucket of Stuff" concept points to both functionality and ethical dilemmas.

Robots And 3D Printing Revolutionize Construction

Robots may soon surpass humans in building affordable, complex structures. Chinese company WinSun and researchers in the U.S. have pioneered robotic 3D printing for constructing homes, indicating potential solutions for global housing crises.

WinSun preprints structural components for assembly at a building site. In contrast, Dr. Steven Keating’s self-driving 3D printing truck delivers foam molds that are filled with concrete, creating durable, fast-built homes. Such methods not only reduce costs but also offer unique architectural designs previously impractical with manual labor.

Automated construction could help in disaster-stricken areas or economically deprived regions. Still, these advancements risk job losses for lower-skill workers and could widen the pay gap, rewarding technical experts handsomely while marginalizing laborers.

Examples

  • WinSun printed layers of concrete to make homes quickly and affordably.
  • Dr. Keating’s printing truck automates both form-making and construction.
  • 3D printing creates aesthetics previously unattainable with manual techniques.

Augmented Reality Will Change How We See And Learn

Augmented Reality (AR) takes virtual reality to the next level by overlaying digital images onto the real world. Unlike VR, AR blends real-life surroundings with interactive information, making it a powerful tool for education and training.

For instance, DAQRI's Smart Helmet overlays virtual instructions during tasks, reducing errors by up to 94% in simulated studies. This technology allows for hands-free learning in jobs and surgeries, significantly improving speed and precision. However, AR’s potential misuse raises concerns, such as privacy breaches when AR glasses recognize strangers’ identities or exploit public spaces without consent.

The rise of games like Pokémon Go also demonstrated AR’s appeal, though negative results unfolded when players intruded in restricted areas. The challenge lies in developing responsible policies while encouraging innovation.

Examples

  • AR tools like the Smart Helmet improve workplace efficiency by 30%.
  • Pokémon Go leveraged AR but caused controversy in sensitive locations.
  • AR in surgeries allows immediate visual overlays of critical patient data.

Synthetic Biology Holds Life-Altering Possibilities

From eradicating malaria to creating lab-grown organs, synthetic biology opens doors to groundbreaking medical possibilities. For instance, genetically engineered mosquitoes might eliminate malaria by spreading resistance genes.

CRISPR-Cas9 is another innovative tool, allowing precision edits in DNA, enabling the removal of diseases from embryos or creating custom biological traits. Similarly, basic synthetic organisms like Syn 3.0, with lab-built genomes, offer vast applications such as breaking down pollution or recycling plastics.

However, ethical questions arise when humanity starts "editing" nature. These include the potential environmental impact of synthetic genetics released into ecosystems or the fairness of "designer babies" where only the wealthy access bespoke genetic modifications.

Examples

  • CRISPR altered genes to combat inherited diseases in lab tests.
  • Syn 3.0 can theoretically break down toxic waste through genetic programming.
  • Synthetic mosquitos engineered for malaria resistance could save millions.

Precision Medicine Combines Data And Biology To Streamline Healthcare

Unlike today’s trial-and-error approach, future medicine aims to provide tailored diagnostics and treatments instantly. Biomarkers, which signal early signs of diseases or mental health changes, could transform healthcare.

MicroRNA, discovered in human blood, serves as one of these biomarkers, providing clues about cancer and its stages. This unlocks the possibility of precise, individualized diets and treatments based on our metabolome, a system of body-specific molecules that define personal health needs.

Mental health can likewise benefit: studies suggest behavioral biomarkers could soon indicate depression symptoms before doctors even observe them manually.

Examples

  • Biomarkers linked to breast cancer allow early preventive treatment.
  • Dr. Danforth analyzed depressed Instagram users by their image filters.
  • MicroRNA guides diagnoses for cancers like leukemia.

Bioprinting Turns Science Fiction Into Life-Saving Technology

For the thousands on organ transplant lists, bioprinting organs offers promising solutions. By carefully using "bio-ink," scientists replicate the cell complexities of human tissue. But the technology is still evolving as researchers work to recreate smaller, trickier structures like blood vessels.

Dr. Jordan Miller's sugar-encased gel approach is testing vascular printing, while Organovo’s bioprinted tissues aid pharmaceutical testing today. While complete organs are years away, printing simpler components like cartilage and ears is already a remarkable feat.

These advances promise to address the critical care gap, removing the need for donors and reducing rejection risks for patients receiving bioprinted replacements.

Examples

  • Princeton researchers printed a 3D human ear using bioprinting.
  • Thin structures like cartilage have been successfully created.
  • Human-like livers reduce dangerous human drug testing scenarios.

Brain-Computer Interfaces Repair More Than They Enhance

While we are far from downloading knowledge directly into our brains, significant progress has been made in repairing lost functions like speech and vision. Brain-computer interfaces (BCIs) are enabling paralyzed patients to control robots, while implants like cochlear devices help the deaf hear.

ECoG technology even lets the brain transmit signals to external hardware, such as computer cursors. In cases of extreme neurological issues like Tourette's or constant epilepsy, deep brain stimulation provides electric impulses to relieve symptoms.

Less invasive experiments with magnetic fields hint at untapped neurology for memory improvements. While these breakthroughs address deficits rather than enhancing abilities, research pushes boundaries daily.

Examples

  • Deep brain stimulation reduces Tourette’s tics through implanted electrodes.
  • Patients move robotic arms with brainwave signals transmitted via ECoG.
  • Magnetic external stimulation shows possibilities for memory recovery.
