Migration in China: Shifting slightly, but still going strong

A new study suggests coastal areas in China are not the migration magnet they used to be

2014-03-13
(Press-News.org) The brain drain of educated workers is still felt most severely in China's central and western provinces, since most knowledge-based industries are generally concentrated in its large coastal cities. However, low-educated migrant workers increasingly find jobs in their home provinces in the central and western regions because of changing economic and government policy. So says Ye Liu and his colleagues of The Chinese University of Hong Kong in Hong Kong and The University of Leeds in the United Kingdom, who carried out a systematic analysis of migration trends in China over the past 25 years. The article is published in Springer's journal Applied Spatial Analysis and Policy.

China's unprecedented surge of internal migration since the early 1980s is the result of unbalanced regional economic development and relaxed migration controls. In the process, 163.4 million migrant workers have moved away from the less-developed interior, mostly to China's coastal regions. Another 240 million migrants are estimated to become city dwellers by 2025. This could increase the urban population to nearly one billion people.

The spatial patterns of age, and education-specific migration mirror the geography of different forms of industries in China. For instance, knowledge-based and advanced service industries that attract educated migrants are highly concentrated in a few large coastal cities such as Beijing and Shanghai. Labor-intensive industries favoring young and low-educated migrant workers are spread across the whole coastal region, where most provinces have become major recipients of less-educated migrants.

However, as a consequence of preferential policies and increasing state investment in industrialization, some interior provinces have recently undergone higher economic growth rates than most coastal provinces. The researchers believe that coastal areas will gradually lose their comparative advantages in developing labor-intensive industries due to the rising labor costs, the evaluation of China's currency and the depletion of land resources.

The authors conclude, "Our findings suggest that massive eastward migration induced by the unbalanced development strategies and the relaxed migration controls still persisted in the first decade of the 21st century, and that the state's recent efforts to alleviate regional inequalities have not resulted in the achievement of equilibrium in China's internal migration system. Nevertheless, as a consequence of preferential policies and increasing state investment, some interior provinces have begun to undergo higher economic growth rates than most coastal provinces in recent years."

Ye and his colleagues continue to explain, "While the coastal areas have made every endeavor to upgrade their industrial structures and develop knowledge-based economies, many interior areas have undergone a tide of industrialization and received many labor-intensive industries that transferred from coastal regions. Under such circumstances, low-educated and young migrant workers increasingly opted to find jobs in their home provinces located in the central and western regions, while educated migrants continued to move towards coastal large cities."

Mount Sinai scientists discover how Marburg virus grows in cells

2014-03-13
New York, NY – A protein that normally protects cells from environmental stresses has been shown to interact Marburg virus VP24, allowing the deadly Marburg virus to live longer and replicate better, according to a cell culture study led by scientists at the Icahn School of Medicine at Mount Sinai. The investigators say that deciphering the molecular details of how Marburg virus and the host protein interact may help in developing inhibitors of the virus. Results from the study are published online March 13 in the peer-reviewed journal Cell Reports. Infections with Marburg ...

Commonly used pain relievers have added benefit of fighting bacterial infection
2014-03-13
Some commonly used drugs that combat aches and pains, fever, and inflammation are also thought to have the ability to kill bacteria. New research appearing online on March 13 in the Cell Press journal Chemistry & Biology reveals that these drugs, better known as NSAIDs, act on bacteria in a way that is fundamentally different from current antibiotics. The discovery could open up new strategies for fighting drug-resistant infections and "superbugs." "We discovered that some anti-inflammatory drugs used in human and veterinary medicine have weak antibiotic activity and ...

Extinct California porpoise had a unique underbite

Extinct California porpoise had a unique underbite
2014-03-13
Millions of years ago, the coast of California was home to a species of porpoise distinguished from its living relatives by a lower jaw that extended well beyond the upper, according to researchers who report their findings in the Cell Press journal Current Biology on March 13. In other words, the long-lost porpoise had a rather distinct and unusual underbite. Careful analysis of the fossilized Semirostrum ceruttii skull also shows that the porpoise's pronounced beak included innervated jaws, which the animal likely used to feel for prey along the ocean floor. "The ...

Humans' ability to digest milk stems from the advent of cattle domestication in Africa

2014-03-13
Most people lose the ability to digest the milk sugar lactose after weaning, but some populations retain high levels of an enzyme called lactase, which allows them to break down lactose in adulthood. In a study published March 13th in the American Journal of Human Genetics, researchers identified genetic factors associated with lactase persistence in African populations and found that this trait became more prevalent in recent history in conjunction with the introduction and spread of cattle domestication in Africa. The findings provide strong evidence that lactase persistence ...

A versatile mouse that can teach us about many diseases and drugs

2014-03-13
Scientists from the UK and Australia have created a mouse that expresses a fluorescing 'biosensor' in every cell of its body, allowing diseased cells and drugs to be tracked and evaluated in real time and in three dimensions. This biosensor mimics the action of a target molecule, in this case a protein known as 'Rac', which drives cell movement in many types of cancer. Rac behaves like a switch, oscillating on the molecular level between two states – active or inactive. When Rac is active, the biosensor picks up chemical cues and glows blue. When Rac is inactive the ...

Penn team links Africans' ability to digest milk to spread of cattle raising

Penn team links Africans ability to digest milk to spread of cattle raising
2014-03-13
Babies are born with the ability to digest lactose, the sugar found in milk, but most humans lose this ability after infancy because of declining levels of the lactose-digesting enzyme lactase. People who maintain high levels of lactase reap the nutritive benefits of milk, however, offering a potential evolutionary advantage to lactase persistence, or what is commonly known as lactose tolerance. A new study led by University of Pennsylvania researchers — constituting the largest investigation ever of lactase persistence in geographically diverse populations of Africans ...

Columbia researchers discover reversible mechanism that increases muscle elasticity

2014-03-13
NEW YORK, NY – How does yoga improve your flexibility? In the Mar 13 cover story of Cell, Columbia University biological sciences professor Julio Fernandez and team report the discovery of a new form of mechanical memory that adjusts the elasticity of muscles to their history of stretching. Using highly sensitive atomic force microscopes, the researchers detected a chemical reaction that increases the elasticity of muscle proteins. Crucially, this reaction targets molecules that have been exposed to a stretching force. This finding changes our understanding of how muscles ...

Researchers identify gene that helps fruit flies go to sleep

2014-03-13
In a series of experiments sparked by fruit flies that couldn't sleep, Johns Hopkins researchers say they have identified a mutant gene — dubbed "Wide Awake" — that sabotages how the biological clock sets the timing for sleep. The finding also led them to the protein made by a normal copy of the gene that promotes sleep early in the night and properly regulates sleep cycles. Because genes and the proteins they code for are often highly conserved across species, the researchers suspect their discoveries — boosted by preliminary studies in mice — could lead to new treatments ...

Human brains 'hard-wired' to link what we see with what we do

2014-03-13
Your brain's ability to instantly link what you see with what you do is down to a dedicated information 'highway', suggests new UCL-led research. For the first time, researchers from UCL (University College London) and Cambridge University have found evidence of a specialized mechanism for spatial self-awareness that combines visual cues with body motion. Standard visual processing is prone to distractions, as it requires us to pay attention to objects of interest and filter out others. The new study has shown that our brains have separate 'hard-wired' systems to visually ...

New view of tumors' evolution

2014-03-13
CAMBRIDGE, MA -- Cancer cells undergo extensive genetic alterations as they grow and spread through the body. Some of these mutations, known as "drivers," help spur cells to grow out of control, while others ("passengers") are merely along for the ride. MIT cancer biologists at the Koch Institute for Integrative Cancer Research and geneticists from the Broad Institute have now performed the most comprehensive analysis to date of these changes in mice programmed to develop cancer. The team discovered mutations and other genetic disturbances that arise at certain stages ...
