    realmadrid ✓ - Real Madrid C. F. condemns all types of racist and xenophobic language and behaviour in football, sport and life in general, such as the regrettable and unfortunate comments made against our player O ViniJr in the last few hours. Real Madrid would like to express its affection and support for Vinicius Junior, a player who regards football as an attitude towards life through joy, respect and sportsmanship. Football is the most global sport there is and should be a model of values and coexistence. The club has directed its legal services to take legal action against anyone who makes racist remarks towards our players.

Could a placebo help heal a broken heart?

The placebo effect is an amazing phenomenon. As we have previously reported, placebos can help with everything from losing weight to improving your vision. And, according to this study, they may even help mend a broken heart. Here, researchers recruited participants who had been dumped in the last six months, and gave them a saline nose-spray that they claimed either was “effective in reducing emotional pain” (the placebo group) or a routine part of fMRI (Functional Magnetic Resonance Imaging) imaging (the control group). Next, the researchers conducted fMRI imaging of the subjects’ brains while showing them photos of their ex-boyfriend/girlfriend, and asking the subjects to recall their breakups. The result? Subjects in the placebo nose spray group experienced less social pain when remembering their exes compared with those in the control. Let’s just hope those participants were well compensated!

Six things I learned from riding in a Google self-driving car 

1 - Human beings are terrible drivers.

We drink. We doze. We text. In the US, 30,000 people die from automobile accidents every year. Traffic crashes are the primary cause of death worldwide for people aged 15-24, and during a crash, 40% of drivers never even hit the brakes. We’re flawed organisms, barreling around at high speeds in vessels covered in glass, metal, distraction, and death. This is one of Google’s “moonshots” – to remove human error from a job which, for the past hundred years, has been entirely human. 

 2 - Google self-driving cars are timid.

The car we rode in did not strike me as dangerous. It drove slowly and deliberately, and I got the impression that it’s more likely to annoy other drivers than to harm them.

In the early versions they tested on closed courses, the vehicles were programmed to be highly aggressive. Apparently during these tests, which involved obstacle courses full of traffic cones and inflatable crash-test objects, there were a lot of screeching brakes, roaring engines and terrified interns. 

 3 - They’re cute.

Google’s new fleet was intentionally designed to look adorable. Our brains are hardwired to treat inanimate (or animate) objects with greater care, caution, and reverence when they resemble a living thing. By turning self-driving cars into an adorable Skynet Marshmallow Bumper Bots, Google hopes to spiritually disarm other drivers. I also suspect the cuteness is used to quell some of the road rage that might emerge from being stuck behind one of these things. They’re intended as moderate-distance couriers, not openroad warriors, so their max speed is 25 miles per hour. 

 4 - It’s not done and it’s not perfect.

Some of the scenarios autonomous vehicles have the most trouble with are the same human beings have the most trouble with, such as traversing four-way stops or handling a yellow light.

The cars use a mixture of 3D laser-mapping, GPS, and radar to analyze and interpret their surroundings, and the latest versions are fully electric with a range of about 100 miles.

Despite the advantages over a human being in certain scenarios, however, these cars still aren’t ready for the real world. They can’t drive in the snow or heavy rain, and there’s a variety of complex situations they do not process well, such as passing through a construction zone. Google is hoping that, eventually, the cars will be able to handle all of this as well (or better) than a human could. 

 5 - I want this technology to succeed, like… yesterday.

I’m biased. Earlier this year my mom had a stroke. It damaged the visual cortex of her brain, and her vision was impaired to the point that she’ll probably never drive again. This reduced her from a fully-functional, independent human being with a career and a buzzing social life into someone who is homebound, disabled, and powerless.

When discussing self-driving cars, people tend to ask many superficial questions. They ignore that 45% of disabled people in the US still work. They ignore that 95% of a car’s lifetime is spent parked. They ignore how this technology could transform the lives of the elderly, or eradicate the need for parking lots or garages or gas stations. They dismiss the entire concept because they don’t think a computer could ever be as good at merging on the freeway as they are. They ignore the great, big, beautiful picture: that this technology could make our lives so much better. 

 6 - It wasn’t an exhilarating ride, and that’s a good thing.

Riding in a self-driving car is not the cybernetic thrill ride one might expect. The car drives like a person, and after a few minutes you forget that you’re being driven autonomously. You forget that a robot is differentiating cars from pedestrians from mopeds from raccoons. You forget that millions of photons are being fired from a laser and interpreting, processing, and reacting to the hand signals of a cyclist. You forget that instead of an organic brain, which has had millions of years to evolve the cognitive ability to fumble its way through a four-way stop, you’re being piloted by an artificial one, which was birthed in less than a decade.

The unfortunate part of something this transformative is the inevitable, ardent stupidity which is going to erupt from the general public. Even if in a few years self-driving cars are proven to be ten times safer than human-operated cars, all it’s going to take is one tragic accident and the public is going to lose their minds. There will be outrage. There will be politicizing. There will be hashtags.

I say look at the bigger picture. All the self-driving cars currently on the road learn from one another, and possess 40 years of driving experience. And this technology is still in its infancy.
