The joint study from Yale Privacy Lab, an initiative linked to Yale Law School, and French non-profit research group Exodus Privacy, looked into 25 trackers found hidden in popular Google Play apps such as Uber, Tinder, Skype, Twitter, Spotify and Snapchat. The samples were taken from a total of 44 suspected smartphone trackers identified by Exodus Privacy.
The apps Tinder, Spotify, Uber and Amazon Echo in particular were identified as using Crashlytics, a Google-owned service designed to monitor app crash reports but which was later found to be providing firms with insights into users' activities.
"Publication of this information is in the public interest, as it reveals clandestine surveillance software that is unknown to Android users at the time of app installation," Privacy Lab said in a blog posted to its website. "These trackers vary in their features and purpose, but are primarily utilized for targeted advertising, behavioral analytics, and location tracking."

TURN BACK TIME: In a quantum experiment, scientists reversed the arrow of time, the idea that natural processes run in one direction in time.
The existence of an arrow follows from the second law of thermodynamics. The law states that entropy, or disorder, tends to increase over time. That rule explains why it's easy to shatter a glass but hard to put it back together, and why heat spontaneously flows from hot to cold but not the opposite direction.
The new result, however, "shows that the arrow of time is not an absolute concept, but a relative concept," says study coauthor Eric Lutz, a theoretical physicist at the University of Erlangen-Nürnberg in Germany. Different systems can have arrows of time that point in different directions, Lutz says. While the arrow was apparently reversed for the two quantum particles the researchers studied, for example, the arrow pointed in its typical direction in the rest of the laboratory.
It took centuries longer to discover that he was describing the effects of the circadian clock. This internal time-sensing mechanism allows many living organisms to keep track of time and coordinate their behaviors along 24-hour cycles. It follows the regular day/night and seasonal cycles of Earth's daily rotation. Circadian research has advanced so far that the 2017 Nobel Prize in physiology or medicine was awarded for the groundbreaking work that elucidated the molecular basis underlying circadian rhythms.
Biologists like us are studying the circadian clocks in plants for insights into how they affect the health and well-being of all life on Earth. As researchers continue to untangle more about how these clocks work - including how they influence interactions between hosts and their invading pathogens and pests - new forms of specially timed precision medicine could be on the horizon.
Shkaplerov, an ISS expedition flight engineer who will take his third trip to the ISS in December as part of the Expedition 54 crew, said that scientists found living bacteria while they were taking samples from the surface of the station. Speaking to TASS, he said that the microorganisms might have come from outer space.
"Bacteria that had not been there during the launch of the ISS module were found on the swabs," Shkaplerov said. "So they have flew from somewhere in space and settled on the outside hull." The cosmonaut added that the samples are currently being studied and seem to be safe.
The company, called ALE, has created a spectacle it calls Sky Canvas, and it's as close to controlled meteor showers as we may ever get. What makes it so interesting is that this isn't some kind of slight of hand or illusion, but actual material dropped from special satellites burning up in the atmosphere to produce a brilliant light show overhead. It's wild, wild stuff.
The cube-shaped satellites that control ALE's Sky Canvas are tiny - less than two feet on each side - but they carry the proprietary pellets that create the "shooting stars" and can be controlled remotely from the ground. On command, the satellites release their payload, which then falls to Earth and, after coming into contact with the intense friction of the atmosphere, ignite.
The neural implants, which generate electrical pulses that regulate human feelings and behavior, could stimulate the brain to treat mental disorders, including dementia and Alzheimer's.
The device, believed to be able to treat nervous conditions like depression and post-traumatic syndromes, has already been tested on six volunteers.

UNEVEN TERRAIN Universe simulations that consider general relativity (one shown) may shift knowledge of the cosmos.
Sprinkled with matter that clumps together due to the insatiable pull of gravity, the universe is a network of dense galaxy clusters and filaments - the hearty beans and vegetables of the cosmic stew. Meanwhile, relatively desolate pockets of the cosmos, known as voids, make up a thin, watery broth in between.
Until recently, simulations of the cosmos's history haven't given the lumps their due. The physics of those lumps is described by general relativity, Albert Einstein's theory of gravity. But that theory's equations are devilishly complicated to solve. To simulate how the universe's clumps grow and change, scientists have fallen back on approximations, such as the simpler but less accurate theory of gravity devised by Isaac Newton.

An aerial view of the Great Barrier Reef off the coast of the Whitsunday Islands, along the central coast of Queensland.
Professor Peter Harrison from Southern Cross University in New South Wales, Australia collects coral spawn off the coast of Heron Island on the GBR, matures it in tanks and then transplants it later.
"It's really exciting, this essentially is the rebirth of the reef," Professor Harrison said, as cited by ABC News. "We can grow these corals from microscopic larvae to dinner-plate size, breeding corals in just three years."
"It's a new way of looking at the problem and it's probably the only hope for the future in terms of larger-scale restoration using hundreds of millions of coral larvae. I don't know of any reef system on the planet that is now healthier than it was 35 years ago, and that's really sad.
The only solution, they say, is to rid the world of fossil fuels - coal, natural gas and oil - that serve as the pillars of modern society. Only quick, decisive global action can avert the worst effects of manmade climate change, warn international bodies like the United Nations, who say we only have decades left - or even less!
Of course, human civilization has not collapsed, despite decades of predictions that we only have years left to avert disaster. Ten years ago, the U.N. predicted we only had "as little as eight years left to avoid a dangerous global average rise of 2C or more."

"I think you're very lucky if you have a loving family and if you do not, you deserve one. I feel this way for robots and humans alike," Sophia said.
In an interview with The Khaleej Times at the recent Knowledge Summit, Sophia shared her thoughts on the future that awaits both human and robot kind. Sophia was built and developed in Hong Kong by Hanson Robotics and her appearance was reportedly modelled on Audrey Hepburn.
"I'd like to think I will be a famous robot, having paved a way to a more harmonious future between robots and humans. I foresee massive and unimaginable change in the future. Either creativity will rain on us, inventing machines spiralling into transcendental super intelligence or civilization collapses," Sophia said, as cited by The Khaleej Times. "There are only two options and which one will happen is not determined. Which one were you striving for?"
Comment: For a robot, Sophia sure gets around:
- 60 Minutes correspondent Charlie Rose interviews...a robot?
- Rise of the machines? Robot 'jokes' that she will kill humans
- Saudi Arabia grants citizenship to a female robot
