Top 10 emerging technologies of 2019 so far.

DNA data storage has become a top 10 emerging technology of 2019 on the World Economic Forum’s annual list.

Other technological breakthroughs with the greatest potential to make a positive impact on our world include social robots, cheaper and safer nuclear reactors, and smarter fertilizers.

The technologies on the list were selected based on their potential to have a mainstream impact on societies and economies within five years and be both disruptive and attractive to investors and researchers.

Technologies emerging today will be shaping the world well into the future, impacting economies and society at large, said Mariette DiChristina, editor-in-chief of Scientific American and chair of the Emerging Technologies Steering Committee.

“Now that we are well into the fourth Industrial Revolution, it’s critical we ensure humanity is served by these new innovations so we can continue to prosper,” DiChristina said.

Let’s take a look at the top 10 emerging technologies of 2019.

Bioplastics for a circular economy

In 2014 alone, industry generated 311 tons of plastics, an amount expected to triple by 2050, according to the World Economic Forum. Yet less than 15 percent of it is recycled. Biodegradable plastics can contribute to the goal of a “circular” plastic economy in which plastics derive from and are converted back to biomass.

Social robots

Robots today are able to recognize voices, faces and emotions; interpret speech and gestures; respond to verbal and nonverbal cues; and even make eye contact. They’re increasingly being used to care for the elderly, educate children and do all sorts of tasks in between.

Metalenses

These lenses are so small that, up until now, it has been impossible to make them through traditional glass-cutting and glass-curving techniques. A breakthrough in the way lenses are produced will allow further miniaturization in sensors and medical imaging devices.

Disordered proteins as drug targets

Intrinsically disordered proteins are proteins that can cause cancer and other diseases. Unlike conventional proteins, they lack a rigid structure, which makes them difficult to treat.

Currently, with the aid of the latest technology, scientists have found a way to prevent their shape-shifting long enough for treatment to have an effect.

Collaborative telepresence

Imagine video conferences where you can not only feel as if you’re in the same room as your correspondents but can actually feel one another’s touch. That’s the potential of collaborative telepresence, which may become the future reality for video meetings.

Smarter fertilizers

Much of the improvement in fertilizers over the years has been in enhancing their ability to slowly release nutrients as and when they are needed, but the drawback is that they still contain ammonia, urea and potash.

The latest versions of smarter fertilizers use more environmentally friendly sources of nitrogen, plus microorganisms that improve uptake by plants.

Advanced food tracking and packaging

Locating the source of food contamination can now take minutes rather than days as a result of a novel blockchain approach to monitoring food progress through the supply chain.

Meanwhile, sensors in packaging can tell us when food is about to spoil, reducing the need to trash whole batches once an expiry date is reached.

Safer nuclear reactors

The great risk with nuclear power is that the fuel rods can overheat and, when mixed with water, produce hydrogen, which can then explode.

New fuels are coming online that are much less likely to overheat and, if they do, produce very little or no hydrogen. The advantage is these new configurations can replace existing fuel rods with little modification.

DNA data storage

At the rate we are producing data, we probably have less than 100 years before the magnetic or optical storage systems we use at the moment will reach maximum capacity. These systems also consume huge amounts of energy. DNA, life’s storage material, has no such limitations. According to one estimate, all the world’s current storage needs for a year could be met by a cube of DNA measuring about one meter on a side.

Utility-scale storage of renewable energy

Lithium-ion batteries will likely be the dominant technology for the next five to 10 years and continuing improvements will result in batteries that can store four to eight hours of energy – long enough, for example, to shift solar-generated power to the evening peak of demand.
