Primes still have the power to surprise.
Prime numbers are the biggest and oldest data set in mathematics. Why have they captivated mathematicians for millennia?
Not creepy at all.

Slacktivism won't cut it in the wake of the Cambridge Analytica scandal.
How should your social media data be accessed and used by researchers?
Harvesting data from Facebook's users is within the rules, I should know, I've done this kind of research myself. But the latest scandal may make it harder for us to get any useful data.
Facebook already controls how its users’ data can be gathered and shared. It’s university ethics boards that need to join the digital age.
The Cambridge Analytica scandal wasn't a data breach – it was a violation of academic ethics. Maybe it's universities, not social networks, that need to update their privacy settings.
Tech companies can use differential privacy to collect and share aggregate data about user habits, while maintaining individual privacy.
How should privacy be protected in a world where data is gathered and shared with increasing speed and ingenuity? Differential privacy, a new model of cyber security, provides a potential solution.
If consumers are unsure of how that data was collected and used they are likely to reject the personalised content.
Brands need to build trust by being transparent about how they collect data.
The use of big data in policing has clear benefits for struggling police forces. But society needs to maintain a critical perspective on moral and ethical grounds.
The global market for predictive analytics is growing.
Business managers often rely on predictive algorithms to make recruiting decisions that affect a company's bottom line. But these kinds of algorithms aren't really "predictive" at all.
Big data provides a rich picture of the physical city, but it won't tell us much about the social city – that's where agent-based modelling comes in.
Images created by NASA with satellite data helped the U.S. Department of Agriculture analyze outbreak patterns for southern pine beetles in Alabama, in spring 2016.
Big data open-access publishing and other advances offer ecologists the ability to forecast events like pest outbreaks over days and seasons rather than decades. But scholars need to seize this opportunity.

Today, there are more refugees and displaced people than ever before. Sophisticated analytics could be a game-changer for officials on the front lines of the crisis.
Artist’s view of Aqua, a NASA satellite in orbit around the Earth since 2002 that studies the water cycle.
Several satellites have been launched in recent years with the objective of measuring data related to climate change. They must be complementary to measurements made on earth.
China has introduced the Social Credit System in 12 demonstration cities.
Millions of Chinese citizens have been blacklisted by Chinese authorities from booking flights or high-speed train tickets due to low social credit scores.
Is it just surfing or is it signal processing?
All earthly and celestial things emit signals. The science of signal processing, born in the 19th Century and now greatly advanced thanks to computers, allows us to better understand them.
Technologies for accessing information need to be somehow future-proofed.
The use of big data at work could promote well-being – but only in very specific conditions.
In the Global Biodiversity Information Facility there are 682,447 records of human encounters with dandelions.
Does big data threaten how humans explore the natural world? We need to protect our impulses to observe, compare, play, discover and love, no matter what technological capabilities are available.
Big data makes it a bit easier to guess your next move.
Predicting human behavior is big business. But science may never be able to do so with perfect certainty.
Telstra and the City of Joondalup have joined forces in a trial of ‘smart park’ applications at Tom Simpson Park.
Public spaces have become more, not less, important to our experience of cities in the digital era. These technologies can be used to confound and enlarge our experiences of and connections to place.
Many cities collect valuable data on themselves.
Many cities lack the resources to analyze their own vast troves of administrative data.
