I have been consistently opposed to feeding a baby regularly. As a doctor, mother and scientist in child development I believe there is nothing to recommend it, from the baby’s point of view.
Mothers, doctors and nurses alike have no idea of where a baby’s blood sugar level lies. All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.
It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night. I’ve never heard anything so ridiculous. Baby feeding shouldn’t follow a timetable set by the mum. What is important is feeding a baby in the best way, though it may cause some inconvenience in the first few weeks.
Well, at last we have copper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding. The research finds out that babies who are fed on demand do better at school at age 5, 7, 11 and 14, than babies fed according to the clock. By the age of 8, their IQ scores are four to five percent higher than babies fed by a rigid（严格的）timetable. This research comes from Oxford and Essex University using a sample of 10,419 children born in the early 1990s, taking account of parental education, family income, a child’s sex and age, the mother’s health and feeding style. These results don’t surprise me. Feeding according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels.
I hope this research will put an end to advocating strictly timed baby feeding practices.

I have a special place in my heart for libraries．I have for as long as I can remember．I was always an enthusiastic reader，sometimes reading up to three books a day as a child．Stories were like air to me and while other kids played ball or went to parties，I lived out adventures through the books I checked out from the library．
My first job was working at the Ukiah Library when I was 16 years old． It was a dream job and I did everything from shelving books to reading to the children for story time．
As I grew older and became a mother， the library took on a new place and an added meaningin my life． I had several children and books were our main source （来源） of entertainment． It was a big deal for us to load up and go to the local library， where my kids could pick out books to read or books they wanted me to read to them．
I always read， using different voices， as though I were acting out the stories with my voice and they loved it! It was a special time to bond with my children and it filled them with the wonderment of books．
Now，I see my children taking their children to the library and I love that the excitement of going to the library lives on from generation to generation．
As a novelist， I've found a new relationship with libraries． I encourage readers to go to their local library when they can't afford to purchase a book． I see libraries as a safe haven （避风港）for readers and writers， a bridge that helps put together a reader with a book． Libraries， in their own way， help fight book piracy （盗版行为）and I think all writers should support libraries in a significant way when they can． Encourage readers to use the library． Share library announcements on your social media． Frequent them and talk about them when you can．

When you were trying to figure out what to buy for the environmentalist on your holiday list，fur probably didn't cross your mind．But some ecologists and fashion（时装）enthusiasts are trying to bring back the market for fur made from nutria（海狸鼠）．
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles．"It sounds crazy to talk about guilt﹣free fur ﹣unless you understand that the nutria are destroying vast wetlands every year，" says Cree McCree，project director of Righteous Fur．
Scientists in Louisiana were so concerned that they decided to pay hunters ＄5 a tail．Some of the fur ends up in the fashion shows like the one in Brooklyn last month．
Nutria were brought there from Argentina by fur farmers and let go into the wild．"The ecosystem down there can't handle this non﹣native species（物种）．It's destroying the environment．It's them or us，" says Michael Massimi，an expert in this field．
The fur trade kept nutria in check for decades，but when the market for nutria collapsedin the late 1980s，the cat﹣sized animals multiplied like crazy．
Biologist Edmond Mouton runs the nutria control program for Louisiana．He says it's not easy to convince people that nutria fur is green，but he has no doubt about it．Hunters bring in more than 300，000 nutria tails a year，so part of Mouton's job these days is trying to promote fur．
Then there's Righteous Fur and its unusual fashions．Model Paige Morgan says，"To give people a guilt﹣free option that they can wear without someone throwing paint on them ﹣ I think that's going to be a massive thing，at least here in New York．" Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable．She's trying to come up with a label to attach to nutria fashions to show it is eco﹣friendly．
（1）What is the purpose of the fashion shows in New Orleans and Brooklyn？

Some parents will buy any high﹣tech toy if they think it will help their child，but researchers said puzzles help children with math﹣related skills．
Psychologist Susan Levine，an expert on mathematics development in young children at the University of Chicago，found children who play with puzzles between ages 2 and 4 later develop better spatial skills．Puzzle play was found to be a significant predictor of cognition（认知）after controlling for differences in parents' income，education and the amount of parent talk，Levine said．
The researchers analyzed video recordings of 53 child﹣parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age．
"The children who played with puzzles performed better than those who did not，on tasks that assessed their ability to rotate（旋转）and translate shapes，" Levine said in a statement．
The parents were asked to interact with their children as they normally would， and about half of the children in the study played with puzzles at one time．Higher﹣income parents tended to have children play with puzzles more frequently，and both boys and girls who played with puzzles had better spatial skills．However，boys tended to play with more complex puzzles than girls，and the parents of boys provided more spatial language and were more active during puzzle play than the parents of girls．
The findings were published in the journal Developmental Science．

The connection between people and plants has long been the subject of scientific research．Recent studies have found positive effects．A study conducted in Youngstown，Ohio，for example，discovered that greener areas of the city experienced less crime．In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants．
The engineers at the Massachusetts Institute of Technology（MIT） have taken it a step further ﹣ changing the actual composition of plants in order to get them to perform diverse，even unusual functions．These include plants that have sensors printed onto their leaves to show when they're short of water and a plant that can detect harmful chemicals in groundwater．"We're thinking about how we can engineer plants to replace functions of the things that we use every day，" explained Michael Strano，a professor of chemical engineering at MIT．
One of his latest projects has been to make plants glow（发光） in experiments using some common vegetables．Strano's team found that they could create a faint light for three﹣and﹣a﹣half hours．The light，about one﹣thousandth of the amount needed to read by，is just a start．The technology，Strano said，could one day be used to light the rooms or even to turn trees into self﹣powered street lamps．
In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a on﹣off treatment that would last the plant's lifetime．The engineers are also trying to develop an on and off "switch" where the glow would fade when exposed to daylight．
Lighting accounts for about 7% of the total electricity consumed in the US．Since lighting is often far removed from the power source（电源） ﹣ such as the distance from a power plant to street lamps on a remote highway ﹣ a lot of energy is lost during transmission（传输）．Glowing plants could reduce this distance and therefore help save energy．
