Rats and other animals need to be highly dependent on social signals from others so they can identify friends to cooperate with and enemies to avoid. To find out if this can 1 to non-living beings, researchers at the University of California tested whether rats can detect social signals from robotic rats.

They 2 eight adult rats with two types of robotic rat — one social ad one asocial. The robot rats were just like a chunkier version of a computer mouse with wheels to move around. During the experiment, the social robot rat followed the living rats around, played with the same toys and opened cage doors to let 3 rats escape. Meanwhile, the asocial robot 4 moved forwards and backwards and side to side.

Next, the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever. The living rats were 52% more likely to set the social robot free than the asocial one. This suggests that the rats perceived the social robot as a genuine social being so that they may have a closer 5 with the social robot. This could lead to the rats better remembering having freed it earlier and wanting the robot to 6 the favour when they get trapped.

Rats have been shown to engage in multiple forms of mutual help and cooperation, including what is referred to as direct reciprocity where a rat will help another rat that has 7 helped them.

The readiness of the rats to befriend the social robots was surprising given their 8 designs. Researchers assumed that they’d have to give them moving heads and tails, facial features, and put a scent on them to make them smell like real rats, which turned out to be unnecessary.

The finding shows how 9 rats are to social cues, even when they come from basic robots. Similarly, children tend to treat robots as if they are 10 beings, even when they display only simple social signals. We humans seem to be fascinated by robots and it turns out that other animals are too.

A Bad Idea

Think you can walk, dive, take phone calls, e-mail and listen to music at the same time? Well, New York's new law says you can't. And you'll be 1 $S100 if you do it on a New York City street.

The law went into force last month, following research and a(n) 2 number of accidents that involved people using electronic gadgets when crossing the street.

Who's to 3 ? Scientists say that our multitasking abilities are limited.

"We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist in Tennessee. “But a major limitation is the inability to 4 on two things at once".

The young people are often considered the great multitaskers. However, an Oxford University research suggests this idea is open to question. A group of 18-to 21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate 5 into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or a(n) 6 message, the older group matched the younger group in speed and 7 .

It is difficult to measure the productivity 8 by multitaskers. But it is probably a lot. Jonathan Spire, chief analyst at Basex. a business-research firm, estimates the cost of interruptions to the American economy at nearly $650 billion a year.

The 9 is based on surveys with office workers. The surveys conclude that 28 percent of the workers' time was spent on interruptions and 10 time before they returned to their main tasks.

Love it or hate it, flying is necessary if we want to get to a faraway destination. For those of us who love to read e-books or listen to music on our phone to 1 the time, however, taking a flight can be a boring experience.

This is because airlines didn’t allow smartphones to be 2 on during flights, even in flight mode. The reason behind the ban is something called electromagnetic interference(电磁干扰). According to a study by plane 3 Boeing in 2014 published by CNN, electromagnetic interference can sometimes cause flight equipment to 4 .

During the study, Kenny Kirchoff, a Boeing engineer, 5 the radio signals sent out by a laptop’s(笔记本电脑的) Wi-Fi radio. He found that some of the signals from the laptop actually jump over the limit, which means there’s a 6 that this piece of equipment could interfere with plane instruments.

This issue is worse with mobile phones, which constantly send and receive strong signals while they search for a 7 to the network. Even in flight mode, many phones still do this.

Despite this, there were just 29 cases of electromagnetic interference caused by mobile phones reported worldwide between 2003 and 2009, according to CNN. Besides, the instruments in modern planes are 8 from electromagnetic interference by metal “shields (护罩)”.

Many airlines are now 9 to allow passengers to use their smartphones freely, meaning that we can finally 10 up on our favorite books and songs while at 30,000 feet in the air.

One of the biggest decisions college students make is what subject to major in. This post-high-school decision will help undergraduates to 1 themselves to an area of study, determining the courses they'll take and setting them on a path toward their careers. Let's take a(n) 2 to step into their shoes and kick around some options, like communications, computer science, playing the bagpipes (风笛).

Playing the bagpipes? In fact, that's one of several…well…unusual majors available to college students today.

Believe it or not, Carnegie Mellon University in Pittsburgh, Pennsylvania, offers a bachelor of fine arts degree in bagpipe performance. Not 3 , it's the only program of its kind in the U.S. For those of you who are unfamiliar with this lively woodwind 4 ， bagpipes are most often heard in Scotland and Ireland, in American parades and special ceremonies, in music practice rooms at Carnegie Mellon (obviously), and 5 anywhere else. So there's probably a scarcity of full-time jobs awaiting a newly graduated bagpiper, which makes this major one of the most unusual offerings in U.S. college catalogs.

If you're looking for a major that's truly outside the box—or literally about the box—how about a bachelor of science in packaging at Michigan State University? The 6 areas of study in this multidisciplinary program include packaging materials (glass, plastic, paper, and metals), packaging processes and systems, design and environmental impact and 7 . With all that knowledge, packaging majors may have their future career all wrapped up and "in the bag" by graduation day.

Are you more the outdoor action-adventure type? Then get out your hiking boots for a bachelor of science degree in adventure education at Plymouth State University in New Hampshire. This too-cool-to-be-true program teaches you how to use the great outdoors to 8 children and adults to adventures that promote self-discovery, personal growth, and a fabulous time. And that means wilderness expeditions, whitewater kayaking, and rock climbing among the natural wonders of the Granite State. Talk about great school field trips!

If none of these options 9 to you but you still want to study something offbeat, don't you worry. There are plenty of other programs to choose from: puppet arts, citrus, comedy, 10 park design, turfgrass science, nautical archaeology, bakery science, and floral management, to name just a few. And if you're finding it hard to make up your mind, then you might want to consider working toward a PhD in decision sciences at Indiana University. This program will teach you how to apply research, data, and analytical tools to make informed business decisions. And it might even help you decide what to minor in.
