Senator Demands Answers After ICE Uses 'Stingray' to Arrest Immigrant. US Immigration and Customs Enforcement has repurposed cellphone tracking technology typically used in criminal investigations to track down at least one immigrant for deportation,The Detroit News revealed last week. ICE’s controversial use of the surveillance technology has caught the eye of Senator Ron Wyden, an Oregon Democrat who is now demanding answers from ICE about its use of cell- site simulators, colloquially known as “Stingrays.” “Stingrays are undoubtedly a useful tool for law enforcement agencies—who have a difficult, dangerous, and important job to do,” Wyden wrote in a letter sent today to ICE acting director Thomas Homan.

Cell- site simulators are capable of vacuuming up large amounts of data from nearby cellphone users and may be useful in pinpointing the locations of known criminals and terrorists. But the devices also pose an inherent risk to communities where they are deployed. The devices can disrupt 9.

Homeland Security and Justice Department policies. Wyden is asking ICE to answer the following questions about its Stingray use before June 3. How many times has ICE used stingrays or similar surveillance technology during each of the last five years to locate individuals in order to arrest and deport them? What policies govern the use of stingrays in immigration enforcement operations? What steps does ICE take during stingray operations to limit interference with or disruptions to the cell phones of innocent Americans?

According to The Detroit News, an ICE spokesperson said that cell- site simulators are “invaluable law enforcement tools that locate or identify mobile devices during active criminal investigations.”Additional reporting by Dell Cameron.

Brilliant Staircase Design Stores Extra Energy to Make It Easier to Climb Later. Do you deliberately avoid visiting friends who live in multi- story buildings without an elevator? No one would fault you—having to climb even just a single flight of stairs is like being forced to workout against your will. But thanks to engineers at Georgia Tech and Emory University, stairs might one day do all the hard work for you. In a paper published today in the journal PLOS ONE, that team details their energy- recycling stairs, which store energy when you descend, and then release it to make the ascent easier on the way back up. You probably don’t stop to think about it while you race down a flight of stairs, but your body expends a considerable amount of energy in the process to prevent you from falling. It’s usually wasted energy, but these energy- recycling stairs take advantage of those forces using a spring- loaded mechanism that compresses each step and locks it down as you descend.

This leaves every step charged with potential energy once you’ve hit the bottom. When you go to climb back up, pressure sensors on each tread release the locking mechanism on the step below it, turning that stored potential energy into kinetic energy that helps lift a climber’s leg as the spring- powered step raises again. As the stairs compress on your descent, the engineers have calculated they save around 2.

And on the way back up, the energy- recycling stairs make it around 3. The stair’s unique mechanisms can be retrofitted to existing steps, so the technology isn’t only for new buildings, necessarily. And installing them would be cheaper, and require less space, than an escalator or elevator. There’s no word on when this technology will be commercialized, but anyone living in an elevator- less building will certainly be hoping it’s as soon as possible.
