More and more studies believe that artificial trans fat is harmful to health

Artificial trans fat, which is once considered a breakthrough invention for prolonging the shelf life of fried and baked food, is considered to be harmful to health.

On the 14 day, who announced a plan to eliminate all trans fats in foods in 5 years. Trans fats, also called trans fatty acids, have a small amount of natural trans fats in beef, sheep, milk and dairy products, and the main source of artificial trans fats is partly hydrogenated vegetable oils. This kind of oil has the advantages of high temperature resistance, no deterioration and long storage. It is commonly used in fried chicken, French fries, cakes and other foods.

The biggest health hazard of trans fats is the increase in people’s risk of cardiovascular disease. According to WHO, more than 500 thousand people die of cardiovascular disease every year because of trans fat intake.

In addition, in recent years, some medical studies have found that trans fat not only endanger health, but also affect mental health. In 2015, a study by the state State University of San Diego found that people with less trans fat intake were better able to control their emotions than those with more trans fats.

On the 14 day, the WHO issued a guideline for action in Geneva, Switzerland. The WHO has called for a complete elimination of artificial trans fats from the food supply chain while reducing natural trans fats, which will be “a major victory for the world’s cardiovascular disease”. The use of healthier oil instead of artificial trans fats can save at least 10 million lives in 25 years.

At present, regulators in some countries require that trans fats must be labeled on food packaging, while some countries are beginning to ban trans fats.

Denmark is the first country in the world to take measures to limit the use of artificial trans fats. For 15 years, the incidence of cardiovascular disease in Denmark has fallen faster than in other developed countries.

The growth of the share accommodation market has become the main force for female landlords

The report shows that in 2017, the scale of the shared accommodation market in China was about RMB145 billion yuan, up 70.6% from the previous year; the number of participants was about 78 million, of which there were about 76 million of the tenants; the number of domestic housing sources shared by the shared accommodation platform was about 3 million sets; the financing amount was about 540 million US dollars, an increase of about 180% over the previous year.

With the growing maturity of the shared economy, the upgrading of cultural tourism consumption and the popularity of the capital market, the shared accommodation industry has attracted more and more water test makers, generating a group of enterprises that lead the development of Airbnb (Epeyoung), piglets and homes.

Which groups are supporting the sharing of the market? Yu Fengxia, deputy director of the National Information Center Sharing Economic Research Center, Yu Fengxia, the Secretary General of the shared accommodation Specialized Committee, gave a group of user portrait: “the active body of the shared accommodation is mainly young users after the 1980s and the post-90s. The 18~30 year old occupants account for more than 70% of the total occupants, and about half of the occupants’ occupancy rate is 1~2 a year. The next time. ”

At the landlord level, the landlords participating in the shared accommodation are young and highly educated. The average age is 33 years old. Most of them are at the age of 28~38, and about 70% of the landlords have a bachelor’s degree or more. Among them, the female landlord became the main force, accounting for about 60%.

From a regional perspective, the two or three line cities of the first tier cities and Chengdu, Chongqing and Xi’an are the mainstream markets for shared accommodation, and the proportion of the landlords and the housing sources in the top ten cities is 48.9% and 47.6% respectively.

From the perspective of order growth, some popular two or three line cities share a sudden increase in share. “The expansion of the region is also reflected in the overseas areas.” Yu Fengxia pointed out that outbound travel led to the sharing of accommodation “go out”, platform enterprises through a variety of forms of strategic cooperation, expanding overseas housing, the layout of the overseas market.

The shortage of long-term care beds has also intensified the demand for homes for the aged and for retired homes

At present, by the date of 2017, the rent area of the national old house is very different, which is the most expensive in Ontario Province, the average monthly cost is $3526, the lowest rent is Quebec Province, and the average of $1678 per month.

Because by 2026, 2 million 400 thousand Canadians reached or exceeded the age of 65. Many of them need to provide “supportive care” nursing homes, which include medication supervision, regular housework management, preparation of meals and all kinds of services.

The DBRS study found that as more baby boomers reach the age of 65, the number of people needing this kind of care by 2046 is expected to reach an astonishing 3 million 300 thousand.

The report says that although the apartment units are built and put into use every year, they are far from meeting their needs. By the number of words, the elderly population increased by 21.7% between 2006 and 2016 in ten, but the increase in the supply of apartment units in the same period was less than half that of the same period.

Laura Tamblyn Watts, director of the Policy Research Department of the Canadian retiree Association CAR, points out that we are not aware of the impact that the baby boomers retire to pension property, but that we do not pay enough attention to the problem, and we have not taken appropriate policies and measures to deal with it.

At the same time, the shortage of long-term care beds also aggravates the demand for homes and homes for the elderly, which makes the old people unable to enjoy government funded facilities and services, and let them lose a good choice for the elderly.

In response to this crisis, the provinces of Canada are very different. BC and opiah are doing well to provide subsidies for pension facilities and retirement homes, but Ontario is very backward.

Sharing bicycles is the most popular new travel mode. The network is about second of the parking spaces

Bain, an international well-known consulting company, published a report in May 16th that China has redefined the concept of travel with a new mode of travel, such as sharing a single car and a network of cars, and becoming the largest travel market in the world, under the double stimulus of the rapid popularization of digital technology and a positive attempt by consumers to try new ways of travel. Traditional car companies need to change their current business models so as to seize new market opportunities.

According to reports, Bain’s recent survey of nearly 2000 consumers in China’s one or two and three line cities showed that shared bicycles were the most popular new mode of travel, and 73% of the respondents said they had used shared bicycles and second, 62% of the visitors said they had used a network of vehicles to replace the vehicles. Travel. More importantly, considering the new way of travel, serious traffic congestion and the financial cost of car maintenance, more Chinese consumers refuse to buy cars.

“These new modes of travel have been popular among Chinese consumers in the market, and they are rapidly becoming popular and fast becoming the mainstream mode of travel.” Bain global partners, report co author Ceng Weimin said.

He believes that as technology continues to integrate, government policy support, as well as more such as B2C sharing cars, such as new mode of travel, the Chinese travel market will be expected to continue to maintain a rapid growth trend.

According to Bain estimates, in the past three years, the market share of domestic shared bicycles and net related cars increased by five times and four times respectively. The total transaction volume of China’s net car market reached about US $23 billion in 2016, which surpassed the total amount of other countries in the world.

Reported that behind this explosive growth, the popularity of mobile payment is one of the main reasons. The congestion of roads and expressways in China’s first and second tier cities is another major reason why consumers turn to new ways of travel.

“More Chinese consumers may choose to give up their cars after taking into account the choices of travel mode, serious traffic congestion and the financial cost of raising cars.” Cai Qing, a global partner at Bain, pointed out.

The report points out that the new travel trend will lead the vehicle factory to rethink its profit pattern, and must cooperate with other service providers and other participants in the value chain.

For example, by working with technology companies, the OEMs can acquire large amounts of consumer data. Through more detailed consumer portraits, car manufacturers can have a better understanding of consumers’ travel scenarios and behaviors. In view of this, they need to build alliances to provide precise marketing based on consumer geography, and other innovative services or products, to expand their role in the travel ecosystem, and to eventually raise income and profit.

The report also says that in the process of growing and shaping trips, there is no doubt that in order to surpass competitors, it is necessary to establish mutually beneficial alliances, enhance the necessary corporate capabilities and prudently manage the risks inherent in the emerging industries. After all, no one in China, the world’s largest travel market, can win alone.

The “Moon Palace 365” experiment ended successfully, and renewed the world record of human closed survival

With the 4 volunteers coming out of the “Moon Palace No. 1” laboratory on 15 days, the Beihang University “Moon Palace 365” experiment was successfully completed, and the world record of human closed survival was refreshed again. The experiment was of great significance for human beings to realize the long-term survival of the earth.

Liu Hong, the chief designer of the Moon Palace No. 1 and professor of Beihang University, said the experiment began in May 10, 2017 and lasted 370 days. It was the longest and most closed biological regenerative life support system in the world, which realized the four life of “human plant animal microorganism” with higher closure and biodiversity. The chain closed loop closed the ecosystem for a long time, and maintained stable physical and mental health.

There were 8 volunteers, all of whom were Beihang University students. They were divided into 2 groups, alternately into the cabin, the first class 60 days, the second class 200 days, and the third 110 days. Among them, the second classes had broken the world record for 180 days in the same system created by Russia. The departure time was delayed 5 days than the original plan, the delay of the cabin was a “intentional” simulation of the sudden situation, and the volunteers in the cabin did not know in advance, mainly to study their psychological state under the sudden situation.

According to Liu Hong, the biological regenerative life support technology used in “Moon Palace one” is a key technology to ensure the long-term survival of human beings on the moon and other extraterrestrial planets. After ten years’ efforts, his team developed the first and the world’s third space base biological regeneration life support foundation comprehensive experimental device, “Moon Palace No. 1”, and successfully completed the first long-term high closure integration experiment for the first time in China for the first time in May 2014, making China become the Third Master of the country after Russia and the United States. A country of technology.

How will the future network shape life in the future? High speed and intelligent understanding of people’s heart

No one can know exactly what the future looks like, but we can take advantage of the current “debris” to overlook it. In the eyes of Liu Yunjie and other scientists, if the Internet is now the road, the future network will be intelligent and high speed. It will not only be fast but also understand you better.

On the intelligent edge network platform of the future network innovation research institute in Jiangsu, China, the consumer behavior of a free WiFi connecting a shopping mall is precisely “portrayed”. Shopping mall has the largest number of people, which stores sell the best, customers like what shopping routes most, through data analysis at a glance.

“This is a microcosm of the future network, and the real economy will take the lead from the future network, because the accuracy of production and sales will be improved by leaps and bounds.” Jiangsu province future network innovation research institute marketing deputy director Xia Keqiang said.

More ordinary people will first feel that the speed of Internet will be greatly improved. The difference from 4G to 5G is like “Bunny jumping” and “cheetah running”. Jiangsu Nanjing will take the lead in realizing 5G business in a small scope in the year, and will achieve scale business by 2020. Just one 5G brings infinite possibilities to the Internet of things, smart city and intelligent transportation. What about artificial intelligence?

“Since 2017, we have made a lot of explorations and attempts in smart cities, smart families, and intelligent industries. For example, the door locks of intelligent household appliances can make the host and visitors live in different places.” Chen Jianhua, general manager of the Industrial Chain Cooperation Department of the China Telecom Co branch of the Internet of things, said that the future network technology will be truly landed through a large number of applications, thus improving production efficiency and facilitating public life.

The experts believe that the future network will develop from the network function and the human-computer to the machine intelligence stage. The zero delay and intelligence of the future network will greatly obscure the concept of space-time. Communication only needs data transmission between nodes, and people can not get greater physical and mental liberation by the need of urban and rural shuttle shuttle. Therefore, from now on to the future, the most important thing is to lay a solid foundation for technology and grasp the entry of future network.

An amazing Mantis’s mimicry

1,Mimicry flower. There is a mantis in the tropics. Its forefoot is transformed into petals, and its body is purple and white. It is hidden in the leaves and looks like a purple and white orchid at first glance. Malaysia has a flower mantis, pink body, looks like a blooming flower, attracted butterflies and honey.

2,Mimicry leaves. Other Mantis grows leaves and protuberances on the chest, abdomen, and joints, and mimics them as leaves, branches and tree scars.

3,Form water droplets. There is a praying mantis in the tropical desert, with a green body, a flat, bright, smooth head in the grass, and a glittering drop of dew on the head of the sun.

4,Intimidate the prey. French biologists once saw a mantis encounter with a large gray locust. When the mantis saw the locusts, the mantis immediately opened its wings and trembled to both sides, and the hind wings stood upright, like a sailboat, the side of the body, the poor snakes, the voice of the venomous snakes, the weight of the whole body on the four feet, and the body stood up, standing still, eyes fixed on the locusts. The locusts moved slightly, the mantis head turned, and the grasshopper was frightened by the frame, slowly lying on the ground, running away, and even moving to the mantis. When it moved to the mantis, the mantis swooped past, and the locust became the food in its mouth without resistance.

For the first time in the deep sea, the scientific research ship was broadcast in the deep sea

In May 8th, the National Natural Science Foundation of China (NSFC) carried out remote controlled unmanned deep sea voyage in the South China Sea.

Deep-sea creatures

The “Kejia” research boat shows the secret world of the sea to the public through live broadcast.

The voyage started in April 17th, and carried out 1 months of scientific expedition, focusing on three main themes: seamounts, deep sea sediments and cold spring systems.

Carry out in-situ observation, experiment and sampling of water depths ranging from 1000 meters to 4000 meters.

At present, the core difficulty of brain like intelligence research and development is that we don’t know enough about the structure and function of brain

The core backbone of the center for excellence in brain science and intelligent technology in the Chinese Academy of Sciences, Professor Bi Guoqiang of University of Science & Technology China, believes that the core difficulty of brain intelligent research and development is that we are not enough to understand the structure and functional principles of the brain.

The human brain weighs about 1.4 kilograms, and the cerebral cortex has hundreds of billions of neurons, each containing tens of thousands of branches, forming a large and fine neural network. The brain is dealing with information through such a large scale neural network system, but the network’s wiring diagram is very complex, and there are many different types of neurons and synapses. It is necessary to imagine a comprehensive and complete line map with modern technology.

“At this stage, we can start building a simplified brain like model without fully understanding the principles of the brain, so as to achieve some” intelligent functions “. Bi Guoqiang, the present artificial neural network model, includes a deep neural network that mimics some of the most basic features of the neural network, and has achieved great success in dealing with the problem of classification recognition, but these “simple” networks have fundamental limitations on efficiency, power consumption, and generality. Ways to produce true intelligence.

“A focus at this stage is the development and application of new technologies, including machine learning (or brain like intelligence) technology, such as the existing artificial neural networks, to promote biological research on the brain network structure and learning rules, to accumulate a large amount of data and to understand the principles.” Bi Guoqiang said.

At the same time, by developing new software and hardware technologies, integrating new brain structures and working principles, the ability to improve brain intelligence technology is tried, which in turn promotes brain research. Through such a positive feedback iteration process, perhaps we can achieve the next breakthrough in the future.
