If you have a dog, you should probably pay more attention to the way your pet responds to other people – it could help you find out who might be mistreating you. According to a new study, dogs tend to reject treats offered by people who were mean to their owners.

Scientists at Kyoto University conducted an experiment which involved three groups of 18 dogs who interacted with their masters and other people in a role-play situation.

The task was the following: the dog owners couldn’t open a box and had to ask for help from one of the two strangers in the room. In the first group, the stranger actively refused to help.

In the second group, the stranger did help the dog owner, and in the third group, both strangers behaved in a neutral way when being asked to help open the box.

After the dogs have witnessed the situation with the box, the two strangers offered them some food. As a result, the dogs in the first group were more likely to accept snacks from the neutral observer rather than from the person who refused to help their owner. At the same time, the dogs in the two other groups showed no preference as to which person to take food from.

According to the researchers, this behavior demonstrates that dogs are make emotional evaluations of people like us and can cooperate socially. We probably didn’t need a study to tell us this, though.

In fact, this ability is very rare in animals and till now was only observed in humans and some primates, such as tufted capuchins. Even human children under 3 years old don’t exhibit this behavior.

We discovered for the first time that dogs make social and emotional evaluations of people regardless of their direct interest. This ability is one of key factors in building a highly collaborative society, and this study shows that dogs share that ability with humans,” said Kazuo Fujita, a professor of comparative cognition at Kyoto University.

It is not the first study to suggest that dogs share some of the human abilities for perception and social behavior. A UK study revealed that dogs perceive speech in a similar way as humans while California University researchers found that dogs can feel jealousy.

Perhaps these similarities have to do with the fact that dogs were domesticated between 9,000 and 34,000 years ago and, as a result, have adopted some patterns of human behavior. These new findings show that there is some scientific evidence backing the well-known saying “Dog is the best friend of man.”

“I’m suspicious of people who don’t like dogs, but I trust a dog when it doesn’t like a person.”

Now go play with your dog! =)

Chinese Military Satellite Smashed by Russian Rocket in “Major Confirmed Orbital Collision”

In an incident that is likely illustrative of things to come, Chinese military satellite 1-02 was smashed after it appears to have collided into the debris from a disintegrating Russian rocket.

The collision, which occurred earlier this year, shows the increasing danger of space junk such as satellite parts and other miscellaneous jetsam littering the Earth’s orbit. An estimated 8,000 metric tons of space debris pose the risk of destroying functional equipment such as weather forecasting systems, telecoms and GPS systems – and even manned space travel missions – if the problem isn’t reined in.

The fate of the Chinese satellite was uncovered by Harvard astrophysicist and satellite tracker Jonathan McDowell.

The breakup of Yunhai 1-02 was initially reported by the U.S. Space Force’s 18th Space Control Squadron (18SPCS). However, it wasn’t until recently that McDowell found out what caused the breakup.

The astrophysicist soon found that it was destroyed by space junk that originated from a Russian Zenit-2 rocket that had launched a spy satellite in 1996. On Aug. 14, McDowell found a strange entry in a database on Space-Track.org: “Collided with satellite.”

 “This is a new kind of comment entry — haven’t seen such a comment for any other satellites before,” McDowell tweeted.

“A quick analysis of the TLEs show that Yunhai 1-02 (44547) and [the debris object] passed within 1 km of each other (so within the uncertainty of the TLEs) at 0741 UTC Mar 18, exactly when 18SPCS reports Yunhai broke up,” he added, noting that this “looks to be the first major confirmed orbital collision in a decade.”

However, the Yunhai satellite still remains functional and is transmitting radio signals, notes Space.com.

The incident shows the growing likelihood of such collisions in the high-traffic, littered near-Earth orbital zone.

“Collisions are proportional to the square of the number of things in orbit,” McDowell explained. “That is to say, if you have 10 times as many satellites, you’re going to get 100 times as many collisions.”

He added: “So, as the traffic density goes up, collisions are going to go from being a minor constituent of the space junk problem to being the major constituent. That’s just math.”

A worst-case scenario of such collisions is known as the “Kessler Syndrome,” and describes the possibility of one collision setting in motion a chain of collisions. Such a disaster was the premise of the 2013 film “Gravity.”

One hopes that things don’t reach that point.

In the meantime, however, there have been a number of initiatives meant to tackle the growing problem of space debris, such as the ELSA-d spacecraft launched in a demonstration mission earlier this year.

Boston Dynamics Drops New Video Of 5-Foot Atlas Humanoid Robot Effortlessly Doing Parkour

Robot maker Boston Dynamics has released new video of its two-legged Atlas robot effortlessly completing a parkour obstacle course, offering a new display of its humanoid machines’ unsettling repertoire.

In the video, a pair of Atlas robots can be seen leaping over large gaps, vaulting beams, and even performing backflips. The robot can even be seen jumping over a board while using its arm to remain steady.

While the display seems like anything but “free” running – as the original developers of parkour had envisioned – the routine does seem like an impressive, if terrifying, display of effective coding that took months to perfect, according to the Hyundai-owned robotics firm.

“It’s not the robot just magically deciding to do parkour, it’s kind of a choreographed routine, much like a skateboard video or a parkour video,” said Atlas control lead Benjamin Stephens.

See for yourself:

Unlike its robotic dog Spot, which controversially hit New York City streets last year before being pulled, Atlas isn’t a production robot. Instead, it’s a research model meant to see how far the limits of robotics can be pushed.

In the past, Boston Dynamics has displayed the robot’s feats with videos of Atlas jogging and even busting out some cool dance moves.

Team lead Scott Kuindersma said in a statement that in about two decades, we can expect to coexist with robots that move “with grace, reliability, and work alongside humans to enrich our lives.”

Until then, some of us will continue to reserve our right to feel a bit queasy about the prospect of people being chased down by these skilled free-running (and dancing) machines.

South Korean Toilet Turns Poo Into Green Energy and Pays Its Users Digital Cash

What if your morning #2 not only powered your stove to cook your eggs, but also allowed you to pay for your coffee and pastry on the way to class?

It seems like an absurd question, but one university in South Korea has invented a toilet that allows human excrement to not only be used for clean power, but also dumps a bit of digital currency into your wallet that can be exchanged for some fruit or cup noodles at the campus canteen, reports Reuters.

The BeeVi toilet – short for Bee-Vision – was designed by urban and environmental engineering professor Cho Jae-weon of the Ulsan National Institute of Science and Technology (UNIST), and is meant to not only save resources but also reward students for their feces.

The toilet is designed to first deliver your excrement into a special underground tank, reducing water use, before microorganisms break the waste down into methane, a clean source of energy that can power the numerous appliances that dorm life requires.

“If we think out of the box, feces has precious value to make energy and manure,” Cho explained. “I have put this value into ecological circulation.”

The toilet can transform approximately a pound of solid human waste – roughly the average amount people poop per day – into some 50 liters of methane gas, said Cho. That’s about enough to generate half a kilowatt hour of electricity, enough to transport a student throughout campus for some of their school day.

Cho has even devised a special virtual currency for the BeeVi toilet called Ggool, or honey in Korean. Users of the toilet can expect to earn 10 Ggool per day, covering some of the many expenses students rack up on campus every day.

Students have given the new system glowing reviews, and don’t even mind discussing their bodily functions at lunchtime – even expressing their hopes to use their fecal credits to purchase books.
