The Cell Phone as Tracking Device

Given incentives like product discounts, consumers are proving eager to hand over mobile phone data to businesses that want to track their movements.

New services are popping up that track people in real time to give businesses a more detailed picture of consumer habits than ever before. The new tracking services go beyond location-based apps such as Foursquare, which require users to actively check in. Rather, these startups connect the dots of where you go without your doing anything at all. In the past, this kind of location data could be obtained only by asking or paying consumers to fill out surveys. Even then, people might not remember exactly where they went after shopping at Target, or they might give the answers that they thought the questioner wanted to hear.

Scientists reactivate cells from 28,000-year-old woolly mammoth

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."

Surprising Science
  • The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
  • Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
  • Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.

While technology develops at exponential speed, transforming how we go about our everyday tasks and extending our lives, it also offers much to worry about. In particular, many top minds think that automation will cost humans their employment, with up to 47% of all jobs gone in the next 25 years. And chances are, this number could be even higher and the massive job loss will come earlier.

Horseshoe crabs are captured for their blue blood. That practice will soon be over.

The blood of horseshoe crabs is harvested on a massive scale in order to retrieve a cell critical to medical research. However, recent innovations might make this practice obsolete.

Surprising Science
  • Horseshoe crabs' blue blood is so valuable that a quart of it can be sold for $15,000.
  • This is because it contains a molecule that is crucial to the medical research community.
  • Today, however, new innovations have resulted in a synthetic substitute that may end the practice of farming horseshoe crabs for their blood.
