Video games can be good for you

11/17/2020
Playing video games is positively linked with wellbeing according research from the Oxford Internet Institute. The new study is the first of its kind as, instead of asking players how much they play, it uses industry data on actual play time for popular video games EA's Plants vs Zombies: Battle for Neighborville and Nintendo's Animal Crossing: New Horizons. The study suggests that experiences of competence and connecting with others through playing the games may contribute to people’s...

Voyager 2 contacted after seven months

11/10/2020
Voyager 2 contacted for the first time since March - says “hello” We reported back in February how scientists at NASA’s Jet Propulsion Laboratory were working flat out repairing Voyager 2.

Who is most susceptible to fake news?

11/3/2020
A new study shows that twitter remains a platform with many conspiracy believers. The work also reveals that compared to the Dutch public, the British are not as good at judging false coronavirus stories to be untrue. The Covid-19 and the Rhetoric of Untruth project - an Anglo-Dutch research initiative – has focussed on the impact of fake news and conspiracy theories during the coronavirus pandemic. Professor Sebastian Groes from Wolverhampton University explains the findings so far. The...

Why do we vote with paper in the age of the smart phone?

10/27/2020
Despite a pandemic, nearly everyone voting in the upcoming US election will do so with a tick in a box on a piece of paper.

Despite the prevalence of paper, there are some voting machines in the USA, Beatrice Atobatele tells us why she bought one online and how hacking into it could help to make the coming...

Go Viral! online game

10/20/2020
Go Viral! is a browser based game where you have a go at being a spreader of misinformation. Along the way, you learn the tactics of the trolls and you come out the other end, better able to differentiate the facts from the alternative facts online. Gareth discusses why these games can change peoples’ minds with one of the game’s co-developers, Jon Roozenbeek of the Department of Psychology at Cambridge University in England. Human rights lawyer Flynn Coleman has just published a book called...

Can political forecasting be quicker? That’s a question posed by Thomas Miller from Northwestern University, who has created a model that simulates a million hypothetical US presidential election results every hour. The model does not use traditional data sources like polling surveys but betting data.

Can AI predict criminal behaviour?

10/6/2020
For at least two decades now police forces have been using crime data tech to analyse crime patterns and therefore reduce crime rates, but they have not been able to predict who may have carried out a crime. Now the Sheriff’s office in Pasco County, Florida is using what it calls ‘intelligence led policing’ to do just that. Could AI algorithms really identify offenders? Not according to Kathleen McGrory, Deputy Investigations Editor at the Tampa Bay Times who has been researching this...

Google maps has a new feature - COVID19 maps. You can now filter onto your chosen area the current Covid-19 case rates. Launched in more than 200 countries the mapping feature could help people decide if they feel it is safe to travel to new areas – but as is often the case with new tech when it is launched it is not as informative as you may have hoped…yet. Charlotte Jee, MIT Technology review reporter, gives us a rundown of what’s good and what’s not so good about the new feature. The...

Keeping the structure of the internet safe

9/22/2020
The Internet Society has created a way of checking how new regulations could harm the structure of the internet. As the internet doesn’t respect borders, what happens in one country can impact the internet in another. The internet can sustain one or two attacks but many at the same time could even bring it down. Until now there has been no way of predicting how such changes could affect the internet’s architecture. The new toolkit also identifies the critical properties that must be...
