Imagination Stage is a children's theater in the state of Maryland. A special performance is put on for children with autism (自闭症) each day. People with autism have difficulty communcating and socializing with other people. Children in the theater are allowed to move around during the performance. It's OK if they shout out or hold their ears when the music is too loud. These special performances are sometimes the only thing that a family can go to the theater together to see if a child has autism.
That is the same idea with Autism on the Seas. This company organizes vacations for families of children with autism, especially vacations on cruise ships. Jamie Grover is director of group development in Autism on the Seas. He said, “With our staff on board, parents know that they are going to be able to relax, enjoy their vacation, and participate in ship activities. They know that their children are well taken care of.”
The benefit of such vacations organized by Autism on the Seas is not waiting in huge lines on departure day. The company has staff to help in the ports. Waiting in long lines or being in the middle of big crowds can cause problem behavior in children with autism. Autism on the Seas helps families avoid situations like that.
Autism on the Seas works with the help of cruise companies like Royal Caribbean. Special times or places are arranged for families to play video games, go skating or rock climbing, or eat dinner. Autism on the Seas also directs families to organizations that can help them pay for these vacations.
Bambi Van Woert from the state of Michigan went on a cruise with her 7-year-old Ben, who has autism. She said, “I would never do something like this myself. I cannot take Ben shopping by myself at this point, so for me to try to do a cruise without help would be absurd.”
Mothers and daughters go through so much—yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped (重叠).
Perri notes with amazement how closely her own life has mirrored her mother's: both have full-time careers； both have published books, articles, and stories； each has three children； they both love to read. They also love to travel—in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature.
A child of the Depression (大萧条), Sheila was raised in Brooklyn by parents who considered education a luxury for girls. Starting with her college education, she has fought for everything she's ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes.
Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can't sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories.
Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration for each other. A written account in two voices, Every Mother Is a Daughter is a duet (二重奏) that produces a deep, strong sound with the experiences that all mothers and daughters will recognize.
Of all nature's disasters, forest fires are often considered the most frightening. Moving at lightning speed, huge walls of flames can burn acres of land in just a few minutes. And although technology, including the use of fire-retardant chemicals, has greatly helped the fight against forest fires, they still do great damage.
According to the National Interagency Fire Center, the fire season last year was the worst on record in terms of the number of fires and acres burned. There were 96. 385 fires and 9.873429 acres affected by fire in a year that was 125% more destructive(毁灭性的) than the10-year average. These fires cost the federal government $1.5 billion to fight, and this figure does not include the money spent by local and state governments as part of the effort.
Fires in the southern states represented half of the national total last year with Texas, Oklahoma and Arkansas being home to a usually high amount of activity. Wildfire has also taken place in Western states such as California, Colorado and Alaska throughout the past 10 years.
It is said that two-thirds of forest fires are started accidentally by people. Almost one quarter are purposely set, while lighting causes 10%.
Forest fires can have advantageous effects. Charcoal(木炭) enriches soil and some plant species(种类) grow well after fire. The cones of the jack pine tree, for example, will not spread their seeds unless there is heat. Douglas fir trees grow best in open sunlight areas after fire.
Everglades National Park (大沼泽地国家公园) is located in the state of Florida. It is the largest wilderness in the entire country and makes up 25% of the wetlands in the state. The park is home to several rare and endangered species. It is also the third largest national park in the US, after Death Valley and Yellowstone. Each year, about 1 million tourists visit the park. On a global level, it has been announced as a World Heritage Site.
Unlike most other national parks, Everglades National Park was created to protect an ecosystem (生态系统) from damage. In 1947, President Harry Truman spoke at the official opening of Everglades National Park, saying the goal of creating the park was to protect forever a wild area that could never be replaced.
10,000 different islands make up Everglades National Park. Each of these islands is lived by natural wildlife. The Everglades is home to about 15 species that are endangered. In addition, more than 350 bird species and 300 species of fresh and saltwater fish live within the park. The Everglades is also home to 40 species of mammals and 50 reptile species.
There are many ways to explore the Everglades. Visitors can see alligators (短吻鳄) while hiking the Anhinga Trail. The Everglades is one of the only places on Earth where freshwater alligators and saltwater crocodiles live in the same area. Visitors using airboats are likely to see large groups of birds. Some visitors might enjoy riding bicycles through Shark Valley. Others may want to move slowly through waters where they can see insects and wildlife closely.
According to experts, changes to the Everglades are becoming a danger to several different kinds of wildlife. They say it is a result of actions the US government began more than 50 years ago, and settlers began even earlier.
Solar energy systems/power plants do not produce air pollution, water pollution, or greenhouse gases. Using solar energy can have a positive, indirect effect on the environment, when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment.
However, some poisonous materials and chemicals are used to make the photovoltaic (光电池的) cells that convert sunlight into electricity. Some solar thermal (保热的) systems use potentially hazardous liquids to transfer heat. Leaks of these materials could be harmful to the environment. U. S. environmental laws regulate the use and settlement of these types of materials.
As with any type of power plant, large solar power plants can affect the environment near their locations. The placement of the power plant may have long-term effects on the habitats of native plants and animals. Some solar power plant-s may require water for cleaning solar collectors and concentrators or for cooling turbine generators. Using large volumes of ground water or surface water in some dry locations may affect the ecosystems that depend on these water resources. In addition, the beam of concentrated sunlight a solar power tower creates can kill birds and insects that fly into the beam.
The amount of solar energy that the earth receives each day is many times greater than the total amount of all energy that people consume each day. However, on the surface of the earth, solar energy is a variable and irregular energy source. The amount of sunlight and the intensity of sunlight varies by time of day and location. Weather and climate conditions affect the availability of sunlight daily and on a seasonal basis. The type and size of a solar energy collection and conversion system determines how much of the available solar energy we can convert into useful energy.
Moscow city authorities have begun using comics (漫画) with characters from Russian fairy tales to explain to migrants (移民) how they should behave. They say a 100-page guide is needed to "keep a positive image" of the city and could help reduce "tensions" between natives and migrants. But critics have pointed out that foreign migrants and natives may be regarded as antagonists in the manual (手册).
Russians and migrants have repeatedly flooded in Moscow recently. Many migrants from ex-Soviet republics in Central Asia, the Caucasus (高加索) and North Caucasus, arrive in Moscow every year, attracted by the capital's job opportunities and relatively high salaries. A significant number of them work in the Russian capital illegally.
The new guide in Russian seeks to explain the "dos" and "don'ts" to migrants. They are urged not to cause trouble, by staring at women, or eating or talking loudly on the streets. They are also warned that the police may routinely (例行公事) stop them to check their documents.
In the manual, Russia's famous "three warriors" are meant to represent the city's law enforcement agencies (执法机关), while Prince Yuri Dolgoruky (a historical character) is used for tours around Moscow. Meanwhile, Vasilisa the Wise and The Snow Maiden test the reader on Russia's language and history. A special section of the book explains the importance of following Moscow's strict residency and employment rules, stressing that migrants could otherwise be deported (驱逐出境) or banned from entry.
The manual was written primarily for illegal migrants, Alexander Kalinin, who heads the group Support for Working Migrants in Moscow, told BBC Russian.
"We want to raise their level of law awareness," he added.
Migrant characters had initially (最初) been identified as representatives of different nationalities, but the book's authors later decided to drop this idea so as "not to offend anyone", said Mr. Kalinin.
"The old conflict between Russian heroes and non-Slavic invaders is being revived," Yevgeny Varshaver, a migration expert told BBC Russian. He also suggested that the language used in the book would be "difficult" to understand for some migrants who were not native Russian speakers.
It's difficult to know the exact answer to whether babies dream and what they dream about. However, sleep experts have shown that newborns dream the most in the first two weeks after birth. Babies spend most of their sleeping time in REM(rapid eye movement) stage. As dreaming takes place in a light state of sleep, newborns tend to wake up due to noises, movements and other factors. When dreaming, newborns make a few noises and their eyes move. They may move around the sides or up and down. They may laugh, scream, or cry during the REM sleep. Also, their facial muscles, hands, and legs move, due to which they may wake up. So wrapping a baby in swaddling(裹紧的) clothes can keep the baby's body from moving and help them sleep better. As babies grow, their body movement decreases when dreaming.
Studies say that the brain activity associated with dreaming is essential for the babies' mental development. During the REM stage, the flow of blood to the brain increases. As a result, certain nerve proteins are produced, which are the building units of the brain. Babies get stimulation from what they see, hear, or feel. The brain processes the information acquired while awake, and stores what is essential to the individual. A study concludes that babies learned while they were dreaming.
What's the time for babies to start dreaming? Researchers say that before birth, babies start experiencing REM sleep around week 25, and so they may start dreaming at the point. On the contrary, some psychologists believe that children start having dreams when they are about 5 years old. At that age, they start becoming aware of themselves and begin to understand the things around them, which is what dreams are actually made of.
You've probably heard about sports coaches, fitness coaches, vocal music teachers, career counselors, psychiatrists (精神病医师) and other specialists who teach skills and help us cope with daily life.
But there's a rapidly growing kind of professional who does a little bit of everything. She or he is called a "life coach". People who are at crossroads in their lives and corporations that want to give certain employees a career boost are turning to them for help.
The idea that one person's success story can change other people's lives for the better goes back at least to the 1930s. Dale Carnegie's famous self-improvement program "How to Win Friends and Influence People" came along soon thereafter.
But this new style of life coaches includes more than enthusiastic speakers or writers. They use their own experiences in business, sports, military service, or psychotherapy (心理疗法) to help others make critical life decisions.
They often give their approach a slogan, such as "energy coaching" or "fearless living" or "working yourself happy".
Dave Lakhani in Boise, Idaho, for instance, works with salespeople to develop what he calls a "road map". He says an ongoing relationship with a coach is like having a personal fitness trainer for one's career and life outside work.
Lakhani's Bold Approach coaching firm also donates some of its time to help people who are anything but successful — including battered women and struggling single mothers.
But others in the so-called "helping professions" are not thrilled about the life-coaching movement. They say that anyone, trained or untrained, can call himself or herself a life coach, and that slick (华而不实的) promoters who mess with people's lives can do more harm than good.

A walker seriously injured in a mountaintop lightning strike which killed two others is showing signs of improvement, the police have said. A major rescue operation was performed on Sunday following two strikes which hit the Brecon Beacons, South Wales. Two men died, while two others were taken to hospital.
A police spokeswoman said, “A man in a serious condition in hospital, following simultaneous (同时发生的) incidents in the Brecon Beacons, has now improved and he is recovering. Officers are continuing to get in touch with the next of relatives of the dead men and enquiries are ongoing. All men were believed to be from England.”
Mark Jones, of the Brecon Mountain Rescue Team, described the lightning strike as a freak accident, and something he had not been called out to in 30 years of service.
The walking group Ramblers Cymru said that while incidents involving thunder and lightning were rare, electrical storms should be taken seriously by walkers.
The organisation's delivery officer, Elly Hannigan Popp, said, "We'd advise everyone to check the weather forecast before starting a walk. If you hear thunder, see lightning or if your hair stands on end, postpone activities even if the sky looks blue and clear. Lightning will strike as far as 10 miles away from any rainfall. Lightning can strike the same place repeatedly — especially tall, pointed, isolated objects."
"If there is no shelter you should keep moving. And if you become the tallest object, crouch (蹲) in the open twice as far away from the nearest pointed object as it is tall. Make yourself as small as possible, stay on your toes and keep your heels together, as it will allow electricity to go up one foot, through the heels and back into the ground through the other."
Queen Bey is now the most-winning female artist, and the most-winning singer, in the 63-year history of the Grammy Awards. She earned 28 trophies including this Sunday's wins for best music video for "Brown Skin Girl" and best rap performance for her "Savage" cooperation with Megan Thee Stallion. She walked into the show with nine nominations, more than anyone else this year.
"As an artist, I believe it's my job, and all of our jobs, to picture the era. It's been such a difficult time," she said in her acceptance speech "So I wanted to sing high praise for all the beautiful Black queens and kings that continue to inspire me and inspire the whole world. This is so overwhelming." she continued.
Beyonce's Grammy-grabbing music career has continued more than 20 years. Her new title puts her among the ranks of artists such as classical music conductor Sir Georg Solti, who has won 31 Grammy trophies and producer Quincy Jones, who also has 28 trophies. She behaved better than previous female record-holder bluegrass singer Alison Krauss, who holds 27 awards. While Beyonce doesn't even need two names to be recognized, she has many names and identities taking her to Grammy glory. As a young superstar with girl group Destiny's Child, she scored awards for "Say My Name" and "Survivor." She played the legendary Etta James in the film "Cadillac Records," landing her best traditional R&B performance for "At Last".
She is the activist and historian telling the stories of Black people through her award-winning "Formation" music video and visual album "Lemonade". She, with her husband Mr. Carter, put their love story on display with the album "Everything is Love," and she is the director, producer, star of "Homecoming." The combination of all these things makes her today's Grammy legend.
UK physicist Isaac Newton once said, ''Nature is pleased with simplicity and nature is no dummy (傻子). '' Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we break the rules, she is likely to be cruel and lash out at us.
The outbreak of the novel coronavirus pneumonia (新型冠状病毒肺炎, NCP) in China and some other countries at the beginning of this year is an example. According to Xinhua News Agency, the new coronavirus is similar to a virus found in a bat in 2017 and probably has an intermediate host (中间宿主). It's believed that the virus originated from the Huanan Seafood Market in Wuhan, Hubei province, where live wild animals were sold.
The Wall Street Journal reported that Dr Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, ''This outbreak is a lesson for us. On a global scale, human population density, wildlife diversity, and land use change are what drive new pandemics (流行病). ''
In ancient times, people needed to rely on nature to survive so they held it in awe (敬畏). For example, the American Indians believed that humans are a part of nature and nature is a part of humans. Chinese ancients always pursued the harmony between nature and human beings.
However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify (改变) plants, capture some wild and rare animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance. For example, cutting a large number of forests means carbon dioxide must build up in the atmosphere and it contributes to global warming.
Although we don't know for sure what first caused the NCP outbreak, Brian Lamacraft at Medium said it's time for people to ''reflect on our relationship with our planet'' and ''reconnect with this world and everything that we've been given''. After all, according to US poet Gary Snyder, ''Nature is not the place to visit. It's our home.''
For a good night's sleep, here is some expert advice: Turn off, turn in and drop off. Anyone who does the opposite—turning on an iPad or other similar electronic readers in bed — may have a harder time both dropping off to sleep and shaking that weak feeling the next morning, a new study found.
Sleep experts at Brigham and Women's Hospital in Boston, found that the light from a tablet computer upsets the body's internal (体内的) clock while reading a printed book does not have the same effect.
An internal clock helps regulate when we sleep. Exposure to the light of day and darkness of night keeps its timing set to a roughly 24-hour cycle. Starting about two hours before bedtime, our brains start to produce a hormone called melatonin (褪黑激素), which signals our internal clock that darkness has fallen and prepares the body for sleep.
Scientists have known for long that light at night can mess with that internal clock. And it does so by suppressing（抑制）melatonin, thus preventing the body from getting the message that bedtime is near.
For their new study, the researchers recruited(招募) six men and six women, all in their mid-20s. Over two weeks, each spent four hours reading each evening before a 10: 00 pm bedtime. The volunteers read on an iPad for five nights in a row. On another five evenings they read a printed book.
Participants took nearly 10 minutes longer to fall asleep, on average, after reading on the iPads. They also spent less time in rapid-eye movement sleep which appears important for learning and storing memories.
There was no difference in hours spent sleeping after reading from either the iPad or a printed book. But how volunteers felt the next day did differ.
"Our most surprising finding is that participants using the e-reader would be more tired and take longer to become alert (警觉的) the next morning, says sleep researcher Ann-Marie Chang.
If you ever get the impression that your dog can "tell" whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.
Researchers trained a group of 11 dogs to distinguish between images（图像）of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face or images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. "We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller. "Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”
"With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller told Live Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions," and this exposure has provided them with many chances to learn to distinguish between them, Muller said.
Dieting to lose weight has become very popular in recent years. People have become more health conscious and try to take better care of their bodies by eating more healthily and exercising more regularly to lose any unnecessary fat that they may have.
Not only are people being more careful about what they eat, they are also concerned with how they eat and how their meals are prepared. People are taking more time for each meal. Many avoid the so-called"plastic" fast-food hamburgers and choose to eat a salad or a sandwich of more healthful ingredients in a quiet restaurant with a more comfortable atmosphere. At home, they also try to take enough time to eat a relaxed dinner without phone or TV interruptions.
While dieting may be viewed as beneficial, it has also become a serious problem for Americans, particularly for young women. Dieting for them has actually become a psychological(心理的) addiction. They eat so little that they can lose as much as fifty percent of their total body weight, and although they look like skeletons, they still insist that they are fat.
The current wave of exercising, dieting and the problems produced have caused many organizations to begin educating the public. Many schools, hospitals, health organizations, newspapers and magazines, for example, are offering classes, printing articles and so on to inform the public of the way to exercise and diet of the dangers of dieting too rapidly, and of the places people can go for medical help if they find themselves on the road to"diet addiction".
When we learn to drive, we need to learn basic skills such as how to switch on the engine, turn on the wipers, operate the brakes, etc. before we actually take to the road. Once the lower order operations and skills listed above have been automatized or at least routinized to the extent that we do not have to pay attention to them (bypass Working Memory's attentional systems), we can actually be safe in the assumption that we can wholly focus on the higher order skills which will allow us to take the split seconds decisions that will prevent us from getting lost, clash with other cars, break the traffic laws while dealing with our children messing about in the back seats.
This is what the brain does, too, when learning languages. Because Working Memory has a very limited space available when performing any task, the brain has learnt to automatize lower order skills so that, by being performed "subconsciously" they free up cognitive(认知)space. So, for instance, if I am an advanced speaker who has routinized accurate pronunciation, grammar and syntax to a fairly high degree, I will be able to devote more conscious attention (Working Memory space) to the message I want to put across. On the other hand, if I still struggle with pronunciation, word order, irregular verb forms and tenses most of my attention will be taken up by the mechanics of what I want to say, rather than the meaning; this will slow me down and limit my ability to think through what I want to say due to cognitive overload.
In language teaching this important principle translates as follows: in order to enable our students to focus on the higher order skills involved in comprehension and production we need to ensure that the lowerorder ones have been acquired or performance will be reduced.
Argentina soccer legend Diego Maradona has died aged 60 of heart failure on Wednesday. Heart failure is a chronic condition that gradually damages the heart's ability to pump blood. Fluid can build up in the lungs as a result — a condition known as pulmonary edema. It is an increasingly common problem that can be fatal.
Regarded as one of the greatest players in the history of the game, Maradona became a household name after inspiring his country to World Cup glory in 1986. He took center stage at the tournament with a memorable performance against England where he scored a symbolic goal that he later described as the "Hand of God".
The small forward out-jumped legendary keeper Peter Shilton and knocked the ball into the net. The goal was allowed to stand, though it was claimed to be a handball. Later in the very game he scored one of the best goals in history after weaving his way past seven English defenders.
His impressive career was also marked by numerous controversies and his notorious lifestyle led to alcoholism and addiction.
Argentina's President Alberto Fernandez announced three days of national mourning for the passing of the superstar, and posted a tribute to Maradona on Twitter. "You took us to the top of the world. You made us feel incredibly happy. You were the greatest of all. Thank you for having existed," it read.
Maradona will lie in honor for public viewing at Argentina's presidential palace. Fans headed to the streets across Argentina and in Naples on Wednesday to pay tribute to
（悼念） their hero. Meanwhile, a minute's silence would be observed ahead of all European matches this week in honor of the Argentine.
"He will go down in history as someone who set football alight and thrilled global fans young and old with his brilliance and skill."
Photo Research
"If you want to be a better photographer, stand in front of better stuff." Photographer Jim Richardson shared it with others. He spends a great deal of time doing photo research, looking for great locations to shoot.
Seeing a wonderful place is bread-and-butter photography—it's just part of the job. Getting there is only half of any great photograph's story. The other half is how the photographer prepares to capture the subject once in front of it. It is believed that groundwork is part of photography, as essential as knowing exposure and lighting or recognizing the decisive moment to take the shot. Research sounds like a boring task for many photographers, while for others digging into a subject in advance is part of the pleasure.
Philosophically, photographers seem to divide along that line. On one side are those who desire only to be in the moment. On the other side are the planners. They would never dream of going out the door without a full list of how they're going to approach the shoot. Actually, there is a third group nowadays. They just take photos of the whole scene and do all the creative work in Photoshop after the event. Most photographers do both: research carefully to prepare their schedule and then act in the moment once on site.
Photographers should do a lot of research in order to get ready for a photographic trip. This includes creating a file for each location they are due to visit. They start a file for each place and begin to make a list of the pieces of information. Knowing what the place looks like in advance is invaluable, so it is good to hit several Internet photo sites. Besides clueing them into the photographic possibilities of the location, this can also show what angles have already become overused and which they should therefore avoid. But photographers will also find angles they didn't expect from locations they hadn't imagined. Armed with these they will be better prepared to push the boundaries of what they expect.
"Above all, I'll look for places and events that are seasonal and timeless. I open my mind to what might make a great subject for a picture," Jim said. "Most travelers tend to think only of places they're visiting, without looking deeper into culture, history or meaning. I try to get in time with the rhythm of the place and in tune with its melody. But most of all I just want to be ready. If I'm ready, I can just about count on being lucky."
According to a recent study, a new kind of genetically modified(转基因的)rice can prevent infections of HIV, the virus responsible for the disease AIDS.
The study reports the newly-developed rice produces proteins(蛋白质)that attach directly to the HIV virus. This process keeps the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.
The Joint United Nations Programme on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017.The organization says the largest number of those is in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.
The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers say the “groundbreaking” discovery is “realistically the only way” that anti-HIV combination treatments can be produced at a cost low enough for the developing world.
They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.
The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to human bodies.
It is food news guaranteed to put a smile on your face. Scientists have found that eating dark chocolate appears to lower the risk of depression by a quarter. While 7.6 percent of the 13,000 people surveyed reported depressive symptoms, just 1.5 percent of the chocolate eaters did.
The study is the first to examine the association with depression according to the type of chocolate consumed. The team assessed data from 13,626 adults from the US National Health and Nutrition Examination Survey. A range of other factors including height, weight, marital status, ethnicity, education, household income, physical activity, smoking and chronic health problems were also taken into account to ensure the study only measured chocolate's effect on depressive symptoms.
After adjusting for these factors, it was found that individuals who reported eating any dark chocolate in two 24-hour periods had 70 percent lower odds of reporting clinically relevant depressive symptoms in the previous two weeks than those who reported not eating chocolate at all.
Chocolate contains a number of psychoactive ingredients which produce a feeling of euphoria. It also contains phenyl ethylamine (苯乙胺), which is believed to be important for regulating people's moods, Dark chocolate also has a higher concentration of flavonoids (类黄酮), alternative when choosing chocolate.
However , British scientists urged caution about the findings, suggesting that the decision to eat dark chocolate could be linked to other health factors. For example people who choose dark chocolate may be more health conscious in general, which is known to protect against depression. Depressed people are also more likely to crave more sugary fatty foods and so could be less likely to pick a dark alternative when choosing chocolate.
