1 . If you are of the “no regrets” school of life, you may think that all this regret is a recipe for unhappiness. But that isn’t the case. Letting yourself be overwhelmed by regret is indeed bad for you. But going to the other extreme may be even worse. To extinguish your regrets doesn’t free you from shame or sorrow but causes you to make the same mistakes again and again. To truly get over our guilt requires that we put regret in its proper place.

2 . In the study, the researchers sought to understand how the brain uses this following information to adjust our perception of what we initially heard. To do this, they conducted a series of experiments in which the subjects listened to isolated syllables and similarly sounding words. Their results produced three primary findings: The brain’s primary auditory cortex (听觉皮层) is sensitive to how ambiguous a speech sound is at just 50 milliseconds after the sound’s appearance. The brain “replays” previous speech sounds while interpreting the following ones, suggesting re-evaluation as the rest of the word unfolds. The brain makes commitments to its “best guess” of how to interpret the signal after about half a second.

3 . After rescuing the lonely animal, Sam and Vera found it extremely emotional to have to release her back out into the wild to fend for herself — even though they knew it was the right thing to do. But after having such a strong bond with an animal, it was really difficult to see her go. They had put so much time, effort and energy into raising her but to see her walking in a herd of blesboks made it all worthwhile.

4 . Since there was usually not enough time for a bystander pig to become involved in the heat of a conflict, though this did occur, Dr Norscia looked at what happened in the three minutes immediately following a fight. Sometimes, he found, the fighters reconciled with each other on their own. The more distantly related the fighters were, the more frequently this happened. Dr Norscia guessed that relations between close relatives are more secure to start with, so rebuilding friendly relations rapidly is less necessary for them.

5 . “Let’s take a break,” partway through the meeting, my boss stood, saying. “I need more coffee.” I picked up my empty cup. “I do, too,” I said, and handed it to him across the table. “Thanks,” I added, looking at him expectantly. The boss was staggered for a moment, and then took the cup from me.

6 . Using first-of-their-kind observations from the James Webb Space Telescope. a University of Minnesota Twin Cities-led team looked more than 13 billion years into the past to discover a unique, minuscule galaxy cluster (星系团) that generated new stars at an extremely high rate for its size. The galaxy is one of the smallest ever discovered at this distance —around 500 million years after the Big Bang — and could help astronomers learn more about galaxies that were present shortly after the universe came into existence.

7 . A listener whose head is in some “sweet spot” hears high-quality sound. But as one gels farther from the sweet spot, the sound diminishes. That’s because sound waves from different loudspeakers interact to cancel out each other’s sound.

8 . Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter. This process requires you to step away from optional online activities for thirty days. At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.

9 . Instantly, we were busily preparing for the worst. The whole family had experienced such a storm before and everyone remembered the damage it had caused to stock and crops. There was very little we could do about the crops. But we needed to protect the animals in case the river flooded again. My older brother called his sheep-dog and began driving our small flock of sheep to higher ground above river. If the river flooded, they should be safe there.

10 . The bus was full, bumpy, and it soon got noisy as her kid began crying because he couldn’t sit next to his mother. There were a couple of open seats, but they weren’t together. She was flustered and looked embarrassed.
