Do you feel like there are too many things to do in a day, but not enough time to do them? If so, you’re experiencing what researchers call time poverty.
If you want a satisfying social life, buy time for it. You might pay to have a disliked housework done by others, get a direct flight instead of a cheaper one with a stopover, or pay extra to drive the fastest route home.
Another way to get more time is to give it away. In one study, researchers asked people to devote part of their Saturday morning to doing something for themselves that they weren’t already planning to do or doing something for someone else. The people who gave away their time later felt like they had more of it.
If you have too many things to do and not enough time to do them, try to cut back on some things.

Autonomously copying other people’s thoughts or options or simply going with the crowd is often referred to as “herd (群体) behaviour”. Herding can appear to make a lot of sense. In an earlier article, I discussed the so-called “wisdom of crowds”, which suggests that average judgments of large groups of people often outperform individual choices.
Psychology research has attempted to model herd behaviour and suggests that the phenomenon relies on the existence of social connections or patterns between individuals as well as specific mechanisms of passing on information. A key condition is the human ability to “mentalize”, which means being able to read and interpret someone else’s mental state and using the information to explain their options. This action of mentalizing is responsible for people’s tendency to attach meaning to options by the herd, even if many behaviours may have come about at random.
Herd behaviours, while common and easy to explain, hold significant dangers. Contrary to the so-called “wisdom of crowds”, which emerges when the judgments of individual group members are independently collected to produce an average opinion, herd behaviours typically rely on so-called “information cascades”, where people take on others’ beliefs or copy their options without critically evaluating the underlying reasons. This frequently leads to the mirroring of unreasonable or stupid behaviours.
Blindly following the herd can be dangerous. So how can we resist the tendency of following the crowd? The sad news is that psychology research suggests that it’s surprisingly difficult to withstand the influences of the herd. In an experiment, researchers found that warning messages about the potential errors of the crowd were surprisingly ineffective in helping subjects make better choices. It appears there is no quick and easy fix. Instead, long-term attitude changes may be necessary, which could involve individuals adopting more critical approaches towards their peers’ opinion, and questioning others’ behaviours as opposed to blindly following them.

Sleep is an ancient, universal experience. But it is only in the past half century or so that it has attracted the attention of dedicated researchers. A new book from Kenneth Miller sets out to record the field’s short but fascinating history.
The early pages of the book, before there is much in the way of established science to describe, are the weakest. A good deal of time is spent on biographical details and portraits of the world through which Nathaniel Kleitman, an influential scientist working on sleep, moved. But the story soon picks up. It roams (漫步) from the discovery of rapid-eye-movement (REM) sleep to the effects of sleep shortage.
One section even describes a modern quantitative research of circadian-rhythm — the biological clocks that govern human’s days — that took place in a purpose — built facility in a Bavarian village. The lab sported two apartments, with no window or clocks to clue their subjects into what was happening outside. Test subjects lived there for weeks, free to wake and sleep whenever they liked — but never free from the thermometers (体温计) that were attached to the wall by long electric lines.
There is a serious side, too. Shift work interferes with the body’s internal clocks and raises the risk of illness. Mr. Miller also explains the slow recognition of sleep apnoea, a common sleep disorder, and the damage it can cause.
Discoveries often lead to new questions in turn. That is why neat, tidy endings are hard to achieve in science books. Despite all the progress of the past 50 years, scientists are still unsure what sleep is for. The fact that it is so widespread suggests it is vital. But why evolution would see it fit to produce animals that must spend large amounts of their time unable to respond to threats is still a mystery researchers are trying to solve. For anyone curious about asking the right questions, however, Mr. Miller’s book is a good place to start.

As the underwater robot OceanOneK carefully navigated toward the upper deck railing of the sunken Italian steamship Le Francesco Crispi about 500 m below the Mediterranean’s surface this month, roboticist Oussama Khatib felt as though he himself were there.
OceanOneK looks like a human diver from the front, with eight multi-directional thrusters (推进器) that allow careful operation underwater. The robot’s touch-based feedback system and 3D vision produced incredibly realistic sensations that equaled what he would have experienced were he down below, rather than above onboard the control ship. Observing through OceanOneK robot’s eyes and feeling through its hands, Khatib perceived a new dimension of colorful life — pink and green and orange — layered on and around the ship. He felt the resistance of the water and could recognize the shapes of the historic relic around him.
The mission of OceanOneK to these depths had two purposes: to explore places no one has gone to before and to show that human touch, vision, and interactivity can be brought to the sites far-removed from where people can operate.
While OceanOneK had many noteworthy adventures and successes during two multi-stop trips around the Mediterranean, the accomplishment of the team and the ship’s crew was demonstrating functional autonomy at nearly 1,000 m down. It was this advance that earned OceanOne’s renaming to OceanOneK.
“This is the first time that a robot has been capable of going to such a depth, interacting with the environment, and permitting the human operator to feel that environment,” said Khatib. “It has been an incredible journey.”
“Distancing humans physically from dangerous and unreachable spaces while connecting their skills and experience to the task promises to fundamentally alter remote work,” said Khatib. “Robotic avatars (化身) will search for and acquire materials, build structures, and perform disaster prevention and recovery operations — be it deep in oceans and mines, at mountain tops, or in space.”
