How Can 'Digital Twins' Determine Right Treatment for Patients?

Research is growing into computational models that will move medicine beyond what works on the average patient. Imagine having a digital twin that gets ill, and can be experimented on to identify the best possible treatment, without you having to go near a pill or a surgeon’s knife.

According to The Guardian, scientists believe that within five to 10 years, “in silico” trials – in which hundreds of virtual organs are used to assess the safety and efficacy of drugs – could become routine, while patient-specific organ models could be used to personalize treatment and avoid medical complications.

Digital twins are computational models of physical objects or processes, updated using data from their real-world counterparts. Within medicine, this means combining vast amounts of data about the workings of genes, proteins, cells and whole-body systems with patients’ personal data to create virtual models of their organs – and eventually, potentially their entire body.

“If you practice medicine today, a lot of it isn’t very scientific. Often, it is equivalent to driving a car and working out where to go next by looking in the rear-view mirror: you try to figure out how to treat the patient in front of you based on people you’ve seen in the past who had similar conditions,” said Prof. Peter Coveney, the director of the Centre for Computational Science at University College London and co-author of Virtual You.

“What a digital twin is doing is using your data inside a model that represents how your physiology and pathology is working. It is not making decisions about you based on a population that might be completely unrepresentative. It is genuinely personalized,” he added.

The current state of the art model can be found in cardiology. Already, companies are using patient-specific heart models to help design medical devices, while the Barcelona-based start-up ELEM BioTech is offering companies the ability to test drugs and devices on simulated models of human hearts.

A statue in Sydney of British explorer James Cook, captain of the first Western ship to reach the east coast of Australia, was sprayed with red paint and damaged two days before Australia's national day, authorities said on Friday.

It was the second time the statue has been defaced and vandalized in the last year. Police said that they had begun an investigation and that several items had been found near the statue.

Local councilor Carolyn Martin said the vandals may have scaled a fence around the statue using a ladder, which they left behind.

"It's an absolute mess," Martin told radio station 2GB. "They have splattered paint all over it, then they have managed to get to the top of the statue and they've knocked his hand off and also part of his face and nose."

For many Indigenous Australians, who trace their lineage on the continent back 50,000 years and make up about 4% of the country's population of 27 million, the Australia Day holiday is known as Invasion Day, symbolizing the destruction of their cultures by European settlers.

Many Indigenous groups want Australia to drop celebrations or move the date, which marks the anniversary of the arrival of the British First Fleet in 1788.

Every year on Jan. 26, protesters rally against the mistreatment of Indigenous people, who are by most socio-economic measures the most disadvantaged people in the country.

A survey by the Sydney Morning Herald newspaper on Friday showed the support to keep Jan. 26 as Australia's national day surged to 61% from 47% over the past two years, signaling a shift in voters' sentiment.
