GUIYANG, Jan. 23 (Xinhua) -- Migrant workers, or off-farm workers, in China should enjoy paid annual family-visit vacations as their urban counterparts, a political advisor in southwest China's Guizhou Province had said."Localities could legislate on the issue on a trail basis," said Yu Peixuan, a member of the Guizhou Provincial Committee of the Chinese People's Political Consultative Conference (CPPCC), made this proposal at the political advisory body's annual session held Jan. 16-22.If migrant workers took paid home leave every year, they would have more time to help their wives in rural homes do the heavy farm work and educate their children, said Yu. "Thus, family ties would be cemented."Statistics show that 47 million women remain at home in rural China when adult males go off to cities to earn their livings.These women played an important role in taking care of the elderly people and children in their rural homes, but they also face many practical difficulties, such as heavy farm work and dull daily life.One of the major factors affecting these women's quality of life was the lack of communications with their husbands, said Yu.Yu called on large enterprises to allow migrant workers to take paid home leave first to set an example for other enterprises.According to the present Labour Law, regular workers at government organs, institutions and state-owned enterprises are eligible for paid vacations of one month per year to visit separated spouses in different cities or regions.

WASHINGTON, May 2 (Xinhua) -- Rice originated in China, a team of U.S. genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing.Their findings, which appear Monday in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of origin -- India as well as China.Asian rice, Oryza sativa, is one of world's oldest crop species. It is also a very diverse crop, with tens of thousands of varieties known throughout the world. Two major subspecies of rice -- japonica and indica -- represent most of the world's varieties. Sushi rice, for example, is a type of japonica, while most of the long-grain rice in risottos are indica.Because rice is so diverse, its origins have been the subject of scientific debate. One theory -- a single-origin model -- suggests that indica and japonica were domesticated once from the wild rice O. rufipogon.Another -- a multiple-origin model -- proposes that these two major rice types were domesticated separately and in different parts of Asia. The multiple-origin model has gained currency in recent years as biologists have observed significant genetic differences between indica and japonica, and several studies examining the evolutionary relationships among rice varieties supported more than domestication in both India and China.In the PNAS study, the researchers re-assessed the evolutionary history, or phylogeny, of domesticated rice using previously published datasets, some of which have been used to argue that indica and japonica rice have separate origins. Using more modern computer algorithms, however, the researchers concluded these two species have the same origin because they have a closer genetic relationship to each other than to any wild rice species found in either India or China.In addition, the study's authors examined the phylogeny of domesticated rice by re-sequencing 630 gene fragments on selected chromosomes from a diverse set of wild and domesticated rice varieties. Using new modeling techniques, which had previously been used to look at genomic data in human evolution, their results showed that the gene sequence data was more consistent with a single origin of rice.In the study, the investigators also used a "molecular clock" of rice genes to see when rice evolved. Depending on how the researchers calibrated their clock, they pinpointed the origin of rice at possibly 8,200 years ago, while japonica and indica split apart from each other about 3,900 years ago. The study's authors pointed out that these molecular dates were consistent with archaeological studies.Archaeologists have uncovered evidence in the last decade for rice domestication in the Yangtze Valley beginning approximately 8, 000 to 9,000 years ago while domestication of rice in the India's Ganges region was around about 4,000 years ago."As rice was brought in from China to India by traders and migrant farmers, it likely hybridized extensively with local wild rice," explained New York University biologist Michael Purugganan, one of the study's co-authors. "So domesticated rice that we may have once thought originated in India actually has its beginnings in China."

BEIJING, Feb. 1 (Xinhua) -- A plane carrying Chinese nationals who were stranded in Egypt arrived at Beijing Capital International Airport Tuesday afternoon.The plane, operated by the Air China International Corporation, arrived in Beijing at 16:50 p.m. Bejing time. The second plane, operated by Hainan Airlines, will arrive in south China's Guangzhou city later Tuesday.The two planes carry a total of 480 Chinese nationals."China has attached great importance to safety of the stranded Chinese nationals since demonstrations and protests broke out in Egypt on Jan. 28," said Chinese Foreign Ministry spokesman Hong Lei at a regular news briefing.Hong said China has taken a package of emergency measures including warning against travel and an around-the-clock hotline to provide consular protection and assistance for the Chinese nationals.The spokesman said that a working taskforce, composed of officials from China's Foreign Ministry, National Tourism Administration, Ministry of Public Security and Civil Aviation Administration, are currently working with the Chinese embassy in Cairo to provide assistance to stranded Chinese in Egypt and to try to facilitate their early return to China.

RIO DE JANEIRO, March 25 (Xinhua) -- The number of dengue fever cases in Rio de Janeiro city this year has already surpassed 10,000, local health authorities said on Friday.According to the city's Health Secretariat, in less than three months, the number of confirmed dengue fever cases in Rio reached 10,158, exceeding the figures registered in the entire years of 2009 (2,723) and 2010 (3,120).In Rio de Janeiro state, the number of confirmed dengue fever cases reached 20,150, and the death toll rose to 18.This week, the first two cases of type-4 dengue fever in Rio de Janeiro state were confirmed in the city of Niteroi. The type-4 dengue fever is not more dangerous than the other types, but as the disease had not been registered in the region before, the local population has no immunity to it.As there are four different types of dengue fever, a person can develop the disease several times.The last epidemic of dengue fever in Rio de Janeiro state occurred in 2008 when 174 people died of the disease and some 250,000 cases of dengue were registered.

NEW YORK, April 13 (Xinhua) -- New York City Mayor Michael Bloomberg and former U.S. President Bill Clinton announced on Wednesday the merger of their environmental groups, hoping to make it the most prominent climate policy organization in the world.The new organization would combine C40, a coalition of international cities run by Bloomberg, and the Clinton Climate Initiative, a project of Clinton' s philanthropic foundation, into a single organization, which will focus on population-rich cities to address global warming."I am elated by this. I think we really have a chance to make a difference," said Bill Clinton during a press conference at Gracie Mansion, adding that "together we are proving it is possible to create jobs and grow economies through reduced emissions."C40 and the Clinton Climate Initiative both seek to cut carbon emissions through programs that reduce energy use in buildings, promote mass transit and reuse greenhouse gases emitted by landfills.The newly combined organization is said to have a budget of about 15 million U.S. dollars. The group will have main offices in New York, Los Angeles and London.
