These are the top 10 emerging technologies of 2019

Which of today's technologies will shape tomorrow's world? A new report compiled by the World Economic Forum reveals some of the breakthrough innovations that are expected to radically impact the global social and economic order.

"From income inequality to climate change, technology will play a critical role in finding solutions to all the challenges our world faces today," says Jeremy Jurgens, Chief Technology Officer at the World Economic Forum. "This year's emerging technologies demonstrate the rapid pace of human innovation and offer a glimpse into what a sustainable, inclusive future will look like."

Making the list involves more than promising major benefits to the world. The emerging technologies must positively disrupt the existing order, be attractive to investors and researchers, and expect to achieve considerable scale within the coming 5 years.

These are the top 10 emerging technologies for 2019:

1. Bioplastics for a circular economy

Less than 15% of the world's plastic is recycled, with the rest incinerated, abandoned or sent to landfill. Biodegradable plastic offers a solution, but lacks the strength of conventional materials. A breakthrough idea promotes the circular economy by using cellulose or lignin from plant waste, which increases material strength without using crops that could otherwise be used for food.

2. Social robots

Today's robots can recognise voices, faces and emotions, interpret speech patterns and gestures, and even make eye contact. Droid friends and assistants are becoming part of everyday life, and are being used increasingly to care of the elderly, educate children and undertake all sorts of tasks in between.

3. Metalenses

Making the lenses used by mobile phones, computers and other electronic devices smaller has been beyond the capabilities of traditional glass cutting and glass curving techniques. But advances in physics have led to miniaturised, lighter alternatives to established lenses, called metalenses. These tiny, thin, flat lenses could replace existing bulky glass lenses and allow further miniaturization in sensors and medical imaging devices.

4. 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 so change shape, making them difficult to treat. Now scientists have found a way to prevent their shape-shifting long enough for treatment to take effect, offering new possibilities for patients.

5. Smarter fertilizers

Recent improvements in fertilizers have focused on their ability to slowly release nutrients when needed. However, they still contain ammonia, urea and potash which damage the environment. New fertilizers use more ecologically friendly sources of nitrogen, and microorganisms that improve take-up by plants.

6. Collaborative telepresence

Imagine a video conference where you not only feel like you're in the same room as the other attendees, you can actually feel one another's touch. A mix of Augmented Reality (AR), Virtual Reality (AR), 5G networks and advanced sensors, mean business people in different locations can physically exchange handshakes, and medical practitioners are able to work remotely with patients as though they are in the same room.
