Machine-learning has predicted death risk in people with serious heart disease faster and more accurately than current methods. New software, developed by scientists at Imperial College London, has created virtual 3D hearts of each patient that replicate the way the organ contracts with each beat. Artificial intelligence is able to rapidly learn which features of cardiac function best predict heart failure and death. The system uses magnetic resonance imaging (MRI) of the heart together with information from blood tests and other observations. The technology has been tested on patients with pulmonary hypertension, a condition that leads to heart failure if not treated appropriately.

Autonomous delivery bots have hit the streets in Washington, D.C., and Redwood City, California, the first two U.S. cities to give the thumbs up to a test run by robotics startup Starship Technologies. According to Recode, the robots started making food deliveries on behalf of Postmates and DoorDash beginning Wednesday. The robots cruise the sidewalk at 4 mph and navigate using nine cameras, GPS, and artificial intelligence software. They are designed to constantly relay information about their route to the entire fleet, allowing them to travel more efficiently over time. According to the company, the bots can traverse curbs and small rocks, and they're smart enough to avoid people and animals.

DAVOS, Switzerland (Reuters) - Open markets and global trade have been blamed for job losses over the last decade, but global CEOs say the real culprits are increasingly machines. And while business leaders gathered at the annual World Economic Forum (WEF) in Davos relish the productivity gains technology can bring, they warned this week that the collateral damage to jobs needs to be addressed more seriously. From taxi drivers to healthcare professionals, technologies such as robotics, driverless cars, artificial intelligence and 3-D printing mean more and more types of jobs are at risk. Adidas, for example, aims to use 3-D printing in the manufacture of some running shoes. "Jobs will be lost, jobs will evolve and this revolution is going to be ageless, it's going to be classless and it's going to affect everyone," said Meg Whitman, chief executive of Hewlett Packard Enterprise.

Whole brain segmentation: automated labeling of neuroanatomical structures in the human brain.

We can use them to sing, shout and whisper sweet nothings. We can use them to activate gadgets and prove who we are to banks. And now researchers believe they can also reveal whether we're getting ill. A US start-up called Canary Speech is developing a way of analysing conversations using machine learning to test for a number of neurological and cognitive diseases, ranging from Parkinson's to dementia. The project was born out of a painful personal experience for the firm's co-founder Henry O'Connell.

Legal tech start-up, Juro, this week announced it had received significant funding to help grow its AI-powered contract system (see story here). Artificial Lawyer caught up with co-founder and former Freshfields lawyer, Richard Mabey to find out more. We discussed how Juro works, the difference between selling legal tech to lawyers and non-lawyers and where the UK-based company is headed. First, congratulations on the $750k in seed funding for Juro, that is a great sign of confidence from what are experienced tech investors. Can you set out for the readers broadly what Juro does?

If your job involves inputting reams of data for a company, you might want to think about retraining in a more specialised field. After industrial robots and international trade put paid to many manufacturing jobs in the West, millions of white-collar workers could now be under threat from new technology such as artificial intelligence (AI). The issue of how best to face up to this "Fourth Industrial Revolution" has been exercising politicians and business leaders this week at the World Economic Forum in the Swiss Alpine town of Davos. The progress of artificial intelligence has been "staggering" in recent years, said Vishal Sikka, chief executive of Indian IT services giant Infosys. "But in many ways we are at the beginning of this evolution and we face the prospect of leaving a larger part of humanity behind than in any other (industrial) advance," he warned.

Fears that accelerating automation is going to eat its lion's share of jobs continue to plague corporate sectors. However, new research from McKinsey Global Institute may talk folks afflicted with automation phobias down from the ledge. The research group says that although half of today's work activities could be automated, it may not happen until 2055. Where the statistic falls along the S curve depends on various factors, such as breakthroughs in artificial intelligence and economic conditions, says Michael Chui, a McKinsey Global Institute partner and an author of the report. Chuiand other researchers analyzed 800 occupations and 2,000 job tasks.

Feedzai develops fraud prevention solutions based on Machine Learning. One of our key differentiators is the ability to put in place such solutions at very large scales and at blazing fast speeds. As clients we have some of the largest payment processors in the world, which gives us access to really, really large dataset. This problem is complex because of the sheer amount of data involved, the very short time to make a decision, and the fact that as soon as you create a better solution, fraudsters start learning to work around it.
