3 . As humans encroach (侵入) more and more on wildlife habitats, animals are finding that the best way to survive isn’t to pack up and move — it’s to adapt to the night life. A variety of previously daytime animals such as foxes, deer and boars have become active at night to avoid human activity out of fear. But this nighttime switch comes with its own risks.
Researchers looked at how 62 species of animals on six continents changed their behavior in response to human activities such as hunting, farming, and development. The studies employed various technologies to follow the animals, from GPS trackers to motion-activated cameras.
Once night falls, the animals surveyed became far more active than they were before humans arrived, bunting and looking for food in the dark. For example, animals that used to split their activity evenly between day and night typically increased their nighttime activity to 68%.
The team also found the animals responded similarly to these human encroachments, regardless of whether human activity directly affected them. So, a deer might become more active at night simply because it sees humans hiking nearby, not because it’s being hunted.
The researchers believe these nighttime behaviors not only allow humans and animals to coexist more peacefully, they may be able to give us hints as to how to plan conservation efforts accordingly, such as limiting human activity during times when a specific species is more active. But moving to the nightlife could also have downsides for these animals. A nighttime lifestyle can reduce an animal’s ability to hunt and find food successfully and can even affect its ability to find a mate. Switching to a nighttime lifestyle can affect natural patterns of life even if these animals are doing so to reduce their interaction with humans. So, just because animals are becoming more active at night doesn’t mean they’ve escaped the influence of humans.

10 . Screen time before bedtime may leave people feeling sleepy in the morning. Cell phones, computers and TVs emit (发出) blue light. And exposure to that bluish light during the two hours before bed can keep us from getting a good night’s rest, a new study finds. It cuts down on the length of people’s sleep. It also leaves them feeling tired in the morning and can disrupt the body clock. Data shows that this blue light tends to make us more alert at night, making it harder to get all the rest we need.
Green and his team surveyed 19 people — all in their 20s — for a sleep study. All spent two hours on a computer right before bedtime. But they didn’t all experience the same light exposure. Looking at screens that gave off intense blue light cut someone’s sleep by about 16 minutes, compared to when they had used screens with red light. Those exposed to blue light also woke up more often at night than if they had been exposed to red light.
“The normal blue light emissions from the computer screen also affect how much melatonin (褪黑素) each volunteer makes. It is released into our blood around 9 p.m. When our bodies make less melatonin, we may still feel too alert at bedtime to fall asleep when the body is tired. And body temperature won’t drop as expected after we use devices emitting lots of blue light. Using screens before bed damages the body’s biological clock,” Green says. “More and more kids are using screens nowadays. Sleep is important, especially during the first few years of life when ‘neural plasticity’ (神经可塑性) is at its greatest. Their brains are still developing the ability to learn and pay attention. That makes the new results worrisome,” Green says.
Rahman says that the new work makes a good point about how blue light from screens can be bad for our bodies. However, he points out, the light in this study is extremely bright. It is far brighter than what a normal computer, tablet or TV will emit. Still, Rahman says the results remind us to think about how we should use screens before bed.
