It’s a common debate between couples — the perfect temperature to keep both warm but not hot. And the temperature’s setting often forms the basis of office arguments between women and men about the “correct” temperature. Research does often show women prefer a higher indoor temperature, compared with men. But why do women feel the cold more?
With the same body weight, women tend to have less muscle to produce heat. Women also have more fat between the skin and the muscles, so the skin feels colder, as it’s slightly further away from blood vessels. Women also tend to have a lower metabolic (新陈代谢) rate than men, which reduces heat production ability during cold exposure, making women more likely to feel cold as the temperature drops. Additionally, the hormones mainly found in women make women’s hands, feet and ears stay around three degrees Celsius cooler than men’s.
The phenomenon that women prefer warmer temperatures isn’t unique to humans. Studies on many species of birds and mammals report that males commonly gather in cooler areas where there is shade, while females and the young stay in warmer environments where there is sunlight. Male bats prefer to rest at the cool, high peaks of mountains, while females remain in the warmer valleys. Female mammals may have developed a preference for warmer climates to encourage them to rest with offspring (幼崽) during stages when the young are unable to regulate their own body temperature. So the difference between heat-sensing systems may provide an advantage.
Couples choosing separate blankets is one way to overcome the differences in temperature preferences. In the workplace, personal comfort systems are heating systems that heat or cool and can be locally placed in individual work stations such as desktops, chairs, or near the feet and legs. Examples include small desk fans, heated chairs and blankets, or footwarmers. These provide individualised thermal comfort (热舒适) to meet personal needs without affecting others in the same space, and have been found to produce higher comfort satisfaction in the workplace.

【推荐2】Scientists have long known that humans are built for endurance. Now, a new study shows people's hearts are also bettered for endurance — though how much depends on whether we run, farm, or stay put on the sofa.
To get to the heart of the matter, researchers examined the hearts of more than 160 adult men from four groups: long-distance runners, sedentary adults, highly trained football player, and the Tarahumara, native American farmers famous for their running ability.
When researchers compared the thickest of the heart's ventricles, they found there were clear differences. Endurance runners and farmers had larger, longer ventricles with thin walls, which could help pump more blood for a long time, the researchers report today in the Proceedings of the National Academy of Sciences. The football player, whose training was short, high-intensity exercise, had shorter, wider ventricles with thicker walls. So did the sedentary humans.
Because high-intensity activity causes blood pressure to increase for a short amount of time, such shorter ventricle, thick walls, and rounder shapes are good for the football players, researchers say, by making sure enough blood is pumped to the brain. But even without those pressures, a couch potato lifestyle seems to result in the same kind of thickening.
But sedentary readers shouldn't feel heartbroken — the researchers said that changes in heart shape are likely reversible, with more endurance activities.

【推荐3】Researchers from Arizona State University (ASU) published their latest report. When men expressed their opinions with anger, people considered them more believable. But when women expressed anger, they were viewed as more emotional (情绪化) and, thus, less trustable. In other words, a man could benefit from using anger in power and persuasion. A woman, however, could be ignored or hurt by her group if she expressed anger.
The study was based on the responses of 210 students. They were shown evidence online from a murder (谋杀) trial. A man was said to have murdered his wife. The students were asked to decide if the man was guilty or not. Before making their decisions, the students discussed the case online with five jurors (陪审员). But these jurors were computers responses and comments. Some of the jurors had male identities. Others had female identities.
Some male jurors were angry about the verdict (裁决). When this happened, the students reacted by doubting their own decisions about the case. Confidence in their responses on the verdict dropped. However, when female jurors seemed angry, the students became more confident in their original verdicts.
Jessica Salerno, a psychologist and co-author of the study, said, “Our results provide something important for any woman who is trying to have an influence on a decision in her workplace and everyday life.”
In a political debate, a female candidate might have less influence if she shows anger. In the entertainment world, actor Jennifer Lawrence recently wrote that women and men in Hollywood get the opposite reactions when expressing their opinions angrily. “All I hear and see are men speaking their opinions,” she wrote. “When I give mine in the quite similar manner, you would have thought I said something annoying”.

【推荐1】When did you last write a letter? Properly write one—by hand? In a digital world, where sending a text or email is far more convenient, is the writing on the wall for traditional pen and paper? Well, some people claim that writing still has many benefits, so maybe it’s not time to ditch your ballpoint or fountain pen yet.
These days, when people request things in writing, a typed, electronic document will be accepted. Doing this on a computer means it could be saved, edited, duplicated and sent via email. But crafting a handwritten document is unique: It requires planning and thought, and, as well as practising your handwriting, it helps you to remember spelling and punctuation.
Some experts believe your brain benefits from using old-fashioned pen and paper. This is particularly relevant for students, where typing notes into a laptop is thought to lack the tactile (触觉的) feedback to the brain that contact between pen and paper does. Hetty Roessingh from the University of Calgary says that “taking notes by hand involves cognitive engagement in summarizing, paraphrasing, organizing, concept and vocabulary mapping.” Others agree that handwriting may boost fine motor skills in your hands and fingers.
There are everyday benefits to using pen and paper too. Scribbling notes, shopping lists or messages on the back of an envelope can still be useful, quick and portable. But putting pen to paper in a letter to a friend or loved one can probably have the most impact. Pen pal writer Katherine Moller told the BBC: “In a world where it is so easy to hop online to email or to send a fast text, it is so personal and so precious to know someone chose to turn off the virtual world to spend some time with you.”
So, while digital skills remain important, don’t write off your pens and pencils yet— especially if your smartphone, tablet or laptop runs out of power!

【推荐2】A new study says electronic toys are not helping babies learn.
“Even if companies are marketing them as educational, they’re not teaching the babies anything at this time,” said the study’s author, Anna Sosa. She is a Northern Arizona University professor who heads the school’s Child Speech and Language Lab.
Sosa and her fellow researchers listened to audio recordings of parents playing with their babies-aged 10 months to 16 months. There searchers compared the experiences when the children played with electronic toys, traditional toys such as blocks, or when the children looked at books.
What they found is that parents talked less with their babies when the babies played with electronic toys.
“The parents talked less, responded less and used fewer content specific words,” Sosa said. Why is this important?
Sosa said research shows that how quickly children develop language is often based on what they hear from parents. When the infants played with electronic toys, parents said little to their children. But with traditional toys, such as blocks, parents shared the names and descriptions of the animals, colors and shapes as their children played, Sosa said.
There was even more information given by parents as their babies looked at the pictures in books, the researcher also said.
Sosa is not telling parents to throw out electronic toys. But she said parents should look at their infants’ play with such toys as entertainment, not a learning experience.
Toy Industry Association spokeswoman Adrienne Appell responded to the study. She said it is important that parents make time to play with their children.
“Playing is a way that kids can learn so much, not only cognitive (认知的) skills, but social and developmental skills,” she said.
She added that play should be balanced, including time for just “make believe” activities, as well as traditional and electronic toys.

【推荐3】Hidden in the mountains of Jordan is the beautiful ancient city of Petra. It lay in ruins for more than a thousand years.
Petra was built in 312 BC by the Nabataeans who were an ancient southern Arab people. They were very skilled at carving(刻). It is no wonder that this ancient city has so much to offer!
In 363 AD, the city suffered from terrible earthquakes that left most of the city damaged. The buildings and the city’s water system were affected. A Swiss explorer, Johann Ludwig Burckhardt, discovered this city of wonders in 1812. Until he discovered Petra, it had been unheard of in the Western world for about 5 centuries!
Petra is the Greek word for stone and this name makes perfect sense because of where the city is located and how some of it is carved into the rock. The ancient city of Petra is also known as the “Rose City”. This is because the rock in which the city is built is a rosered colour. Many of the buildings of Petra have beautiful facades(正面). Some of the facades have columns(柱) carved into the rock, but they are for decoration and they don’t actually hold anything up.
Petra was built in the middle of the desert, where it hardly ever rained. Luckily, the Nabataeans were very skilled engineers and knew how to live in a hot and dry place. First, they carved channels(渠) to bring water from a nearby spring into the city. Rainwater was also collected in underground channels. The water was then stored. So, even in the long dry months there was enough water for people to use.
Today, Petra is one of the world’s most famous ancient sites and people come from all over the world to visit it.
