1 . The use of AI (artificial intelligence) is becoming more common in many branches of industry and online shopping. Traditional lines of work, such as goods transport and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient (高效的) the use of AI can be in the commercial management of trucks.

“Digital applications—as well as machine leaning, a kind of AI—are increasingly applied to operations and courses in the transport area,” explains Professor Matthias Klumpp from the Faculty of Economics. “The question in the commercial area, however, is whether or not this contributes to achieving goals.”

To answer this question, the researchers compared the work efficiency of truck drivers with their main use of AI applications. Looking at trade delivery by truck, they studied three groups: the first drove completely following human decision-making models; the second used a combination of human and machine; and the third depended completely on fully automated decisions.

The researchers found that an intelligent combination of human work and decision-making abilities with AI applications promises the highest transport and driving efficiency. “On average, the second group achieved the most efficient transport trips, with the fewest interventions (干预) and off-course from the best path.” one researcher said, “Clearly, neither a completely human decision-making structure nor a fully automated driving system can promise to meet current goods transport requirements.” The scientists therefore summarized that despite the progress of AI in the field of transportation by truck, human experience and decision-making abilities will still be necessary in the longer term. However, the challenge is that a wide range of training and qualification (资格) needs will come along by working with Al applications, especially for simple goods transport activities.

2 . When you hear the beginning of your favorite song from the radio, suddenly your neck is covered in goose bumps.

It's such a thing that a group of scientists call “skin excitement”—a feeling of cold caused not by a drop in temperature or sudden scare, but by the sense of beauty. “Skin excitement” can come from a song, a painting, a moving movie scene, or even a beloved memory-pretty much anything that causes the giving out of pleasure-soaked dopamine in your brain. But it does not come for all of us.

Your favorite music uncovers a lot about your personality，and so does how you respond to that music. Studies suppose that as few as 55 percent of people experience “skin excitement” when listening to music. And if you count yourself among this group, the goose bumps on your skin aren't the only giveaway—scientists can read it in your brain, too. In a new study published in the journal Social Cognitive and Affective Neuroscience, Harvard researchers performed brain scans on 10 students who said they reliably got cold when listening to music, and 10 students who didn't. They found that the cold-prone brains may really be excited by stronger emotions.

Cold-prone brains are generally more likely to show stronger emotional intelligence than no-cold brains. Cold-prone minds tend to have unusual active imagination, reflect more deeply on their emotions, and appreciate nature and the beauty of music and art to a stronger degree than no-cold brains.

So, what type of music causes the chills? It seems that the type is not so important; participants in the new study reported getting cold from songs of every kind. And any song connected with a strong emotional memory of the listener can produce the most reliable results. For me, that's the song Sailing to Philadelphia by Mark Knopfler, which I listened to as a kid in the car with my dad, on the way to the summer camp.
