Researchers believe they can predict how long you will live using big data

Researchers from the University of East Anglia (UEA) claim they can predict life expectancy by studying data collected by healthcare providers.

Statisticians, computer scientists and medics from UEA have launched a four-year project that will test how factors such as lifestyle, medical conditions and medical interventions affect “mortality and longevity”.

“People around the world are living longer. We want to develop software tools that use big data routinely collected by healthcare providers to forecast longevity,” said lead researcher, Prof Elena Kulinskaya.

“When we talk about Big Data what we mean is data that is vast, complex and difficult to analyse. We want to be able to use it to see statistical life expectancy trends, based on large-scale population-based data collected over the long term.”

The research team imagine that using big data to predict lifespan will benefit both patients and healthcare providers.

Knowing how long you are likely to live benefits patients by helping them plan for retirement, while healthcare providers will enjoy savings from knowing how particular drugs such as statins or beta-blockers affect longevity.

“Pension contributions were recently freed, so now people can take their pension pots out and use them as they wish. But to be able to plan for retirement, and to understand how much you can spend, it is good to have some idea of your life expectancy,” said Prof Kulinskaya.

“As well as being useful for people planning retirement, it is also important for GPs deciding whether and when to prescribe particular drugs or how to advise their patients. It could also benefit local health authorities planning resources, and insurance companies deciding on the size of pension you can buy with your pension pot.”

The research project, called ‘Use of Big Health and Actuarial Data for Understanding Longevity and Morbidity Risks’, is particularly focused on finding out how various chronic diseases and their treatments impact life expectancy.

However, the team from UEA aren’t the only researchers trying to unlock the value of big data to healthcare.

Big Data Partnership are currently involved in a project that aims to use big data analysis to reduce complications associated with type 2 diabetes.

School will use facial analysis to identify students who are dozing off

In September the ESG business school in Paris will begin using artificial intelligence and facial analysis to determine whether students are paying attention in class. The school says the technology will be used to improve performance of students and professors.

The brain starts to eat itself after chronic sleep deprivation

Brain cells that destroy and digest worn-out cells and debris go into overdrive in mice that are chronically sleep-deprived. The discovery could explain why a chronic lack of sleep puts people at risk of neurological disorders like Alzheimer’s disease.

Juno mission: Jupiter’s magnetic field is even weirder than expected

It has long been known that Jupiter has the most intense magnetic field in the solar system, but the first round of results from NASA’s Juno mission has revealed that it is far stronger and more misshapen than scientists predicted.

Announcing the findings of the spacecraft’s first data-collection pass, which saw Juno fly within 2,600 miles (4,200km) of Jupiter on 27th August 2016, NASA mission scientists revealed that the planet far surpassed the expectations of models.

Measuring Jupiter’s magnetosphere using Juno’s magnetometer investigation (MAG) tool, they found that the planet’s magnetic field is even stronger than models predicted, at 7.766 Gaus: 10 times stronger than the strongest fields on Earth.

Furthermore, it is far more irregular in shape, prompting a re-think about how it could be generated.

“Juno is giving us a view of the magnetic field close to Jupiter that we’ve never had before,” said Jack Connerney, Juno deputy principal investigator and magnetic field investigation lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“Already we see that the magnetic field looks lumpy: it is stronger in some places and weaker in others.

At present, scientists cannot say for certain why or how Jupiter’s magnetic field is so peculiar, but they do already have a theory: that the field is not generated from the planet’s core, but in a layer closer to its surface.

“This uneven distribution suggests that the field might be generated by dynamo action closer to the surface, above the layer of metallic hydrogen,” said Connerney.

However, with many more flybys planned, the scientists will considerable opportunities to learn more about this phenomenon, and more accurately pinpoint the bizarre magnetic field’s cause.

“Every flyby we execute gets us closer to determining where and how Jupiter’s dynamo works,” added Connerney.

With each flyby, which occurs every 53 days, the scientists are treated to a 6MB haul of newly collected information, which takes around 1.5 days to transfer back to Earth.

“Every 53 days, we go screaming by Jupiter, get doused by a fire hose of Jovian science, and there is always something new,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio.

An unexpected magnetic field was not the only surprise from the first data haul. The mission also provided a first-look at Jupiter’s poles, which are unexpectedly covered in swirling, densely clustered storms the size of Earth.

“We’re puzzled as to how they could be formed, how stable the configuration is, and why Jupiter’s north pole doesn’t look like the south pole,” said Bolton. “We’re questioning whether this is a dynamic system, and are we seeing just one stage, and over the next year, we’re going to watch it disappear, or is this a stable configuration and these storms are circulating around one another?”

Juno’s Microwave Radiometer (MWR) also threw up some surprises, with some of the planet’s belts appearing to penetrate down to its surface, while others seem to evolve into other structures. It’s a curious phenomenon, and one which the scientists hope to better explore on future flybys.

“On our next flyby on July 11, we will fly directly over one of the most iconic features in the entire solar system – one that every school kid knows – Jupiter’s Great Red Spot,” said Bolton.

“If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it’s Juno and her cloud-piercing science instruments.”
