Answer:
Microneedles for painless injections and tests
These tiny needles, at no more than the depth of a sheet of paper and the width of a human hair, could bring us pain-free injections and blood testing. “Microneedles” penetrate the skin without troubling underlying nerve endings, and can be attached to syringes or patches, or even mixed into creams. They could allow blood tests to be done at home and sent to the lab or analyzed on the spot. And because their use doesn’t require expensive equipment or high levels of training, testing and treatment could be delivered in under-served areas – making care more accessible.
2. Sun-powered chemistry
Making many of the chemicals we rely on requires fossil fuels. But a new approach holds the promise of reducing the sector’s emissions by using sunlight to convert waste carbon dioxide into useful chemicals. Recent developments in the sunlight-activated catalysts needed for this process are a step towards creating “solar” refineries to produce useful compounds from the waste gas, which could be turned into everything from medicines and detergents to fertilizers and textiles.
3. Virtual patients
If the goal of swapping humans for simulations to make clinical trials faster and safer sounds simple, the science behind it is anything but. Data taken from high-res images of a human organ is fed into a complex mathematical model of the mechanisms that control that organ’s function. Then, computer algorithms resolve the resulting equations and generate a virtual organ that behaves like the real thing. Such virtual organs or body systems could replace people in the initial assessments of drugs and treatments, making the process quicker, safer and less expensive.
4. Spatial computing
Spatial computing is the next step in the bringing together of physical and digital worlds we’re already seeing with virtual-reality and augmented-reality apps. As with VR and AR, it digitizes objects that connect via the cloud, allows sensors and motors to react to one another and creates a digital representation of the real world. But it goes even further, adding spatial mapping that lets a computer “coordinator” track and control the movements and interactions of objects as a person moves through the digital or physical world. This technology will bring new developments in how people and machines interact, in industry, healthcare, transportation and the home.
