BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S.The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved.As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition.Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added

OTTAWA, Nov. 21 (Xinhua) -- The leader of World Health Organization (WHO) Margaret Chan said in Canada on Monday that countries must make the health of women and children their highest priority.Speaking at a luncheon in Gatineau, Quebec, Chan said that maternal and infant health is the most pressing public health issue in the world.She made the remarks just hours after WHO announced Chan was the only candidate for the position on WHO director-general when Chan's appointment expires next year.An executive board meeting in Geneva between Jan. 16 and 23 will decide whether to put the name forward to the WHO Assembly in May, which would make the final decision regarding the appointment.Chan, a former health chief in China's Hong Kong, was elected director-general of the WHO in Nov. 2006.Before her tenure with WHO, Chan was head of public health in Hong Kong, where she managed the city's response to the world's first outbreak of the deadly H5N1 bird flu virus and an outbreak of Severe Acute Respiratory Syndrome (SARS).Speaking in Gatineau, Chan, who earned her medical degree in Canada, said that she never expected to rise to such a lofty position."I just wanted to be a doctor. I just wanted to take care of women and children. When I was studying in Canada, I thought I would get married and have children. I never guessed I'd do anything like head the World Health Organization," she said.She said that she will continue to focus the WHO's attention on mothers and young children.Chan said that it's difficult to know how many mothers and young children die of preventable diseases, since more than 80 countries don't keep accurate death records, but she said that millions of children under five years of age are dying.Millions more are growing up physically and mentally stunted because of poor nutrition and medical care, she added."Without proper nutrition, the stunting we are seeing is horrific," she said. Unless babies have good food, including being breast-fed as infants, they grow up physically and mentally under-developed, Chan said."The first few years of a child's life are make or break," she said.Chan and the WHO held a meeting of the Expert Panel on Maternal and Child Health in Canada from Nov. 18 to Nov. 21. The panel was established by the United Nations Commission on Information and Accountability for Women's and Children's Health Report. At the invitation of the WHO, the Commission was co-chaired by Canada's Prime Minister Stephen Harper and the President of Tanzania, Dr. Jakaya Kikwete.Chan says she's hopeful funding from developed nations will continue to expand, despite the debt crisis facing many of them. The situation resembles the 1970s, with spikes in energy and food prices along with cuts to national budgets to restrain debt.Chan said she is relieved the International Monetary Fund will not press for public health cuts in countries that are struggling with debt.Beverley J. Oda, Minister of International Cooperation who is responsible for Canada's official aid affairs, delivered remarks at the luncheon on improving the health of children and mothers locally and globally."I am particularly proud of the strong partnership between the WHO and Canada in advancing global health, and working towards improvements that will help us achieve our shared goals," she said.Last Friday, Oda announced 25 new initiatives to further Canada 's support to 23 projects in Africa concerning Children and Youth, Food Security and Sustainable Economic Growth.Seven of these are multi-country projects supporting efforts to prevent the mother-to-child transmission of HIV/AIDS, further improving child health, or increasing the capacity of African Regional Technical Centres. The others are targeted to support work in a range of individual African countries by working with Canadian, international and African-based organizations.

BEIJING, Dec. 30 (Xinhua) -- China will push to properly resolve the case of a Chinese skipper indicted by Japan, the Foreign Ministry said Friday.Spokesman Hong Lei said this is a common fishing case, and the Chinese embassy in Japan has dispatched officials to visit the skipper.China requests that Japan ensure the rights of the Chinese skipper, Hong said, and China is communicating closely with Japan in order to properly resolve the case.The Chinese government has been requiring fishermen to fish legally, Hong said, adding that the competent authorities have done a lot in this area, and he promised to promote the management and education of Chinese fishermen.Japanese prosecutors have indicted the captain of a Chinese fishing boat for illegally operating in Japanese waters, a local official said Friday.The Nagasaki District Public Prosecutors Office has finalized its case against Zhong Jinyin, 39, following his December 20 arrest near islands off southwest Japan, according to the official.The prosecutors have not indicated whether the skipper has admitted to the charge.

WASHINGTON, Nov. 10 (Xinhua) -- Using its near-infrared vision to peer nine billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation, the U.S. space agency announced on Thursday.While dwarf galaxies represent the most common type of galaxy in the universe, the rapid star-birth observed in these newly- found examples may force astronomers to reassess their understanding of the ways in which galaxies form.The galaxies are a hundred times less massive, on average, than the Milky Way, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its star population.The universe is estimated to be 13.7 billion years old, and these newly-discovered galaxies are extreme even for the young universe -- when most galaxies were forming stars at higher rates than they are today. Astronomers using Hubble's instruments could spot the galaxies because the radiation from young, hot stars has caused the oxygen in the gas surrounding them to light up like a bright neon sign."The galaxies have been there all along, but up until recently astronomers have been able only to survey tiny patches of sky at the sensitivities necessary to detect them," said Arjen van der Wel of the Max Planck Institute for Astronomy in Germany, lead author of a paper on the results to be published online on Nov. 14 in The Astrophysical Journal. "We weren't looking specifically for these galaxies, but they stood out because of their unusual colors. "The observations were part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an ambitious three- year study to analyze the most distant galaxies in the universe. CANDELS is the first census of dwarf galaxies at such an early epoch."In addition to the images, Hubble has captured spectra that show us the oxygen in a handful of galaxies and confirmed their extreme star-forming nature," said co-author Amber Straughn at NASA's Goddard Space Flight Center. "Spectra are like fingerprints. They tell us the galaxies' chemical composition."The CANDELS team uncovered the 69 young dwarf galaxies in near- infrared images taken with Hubble's Wide Field Camera 3 and Advanced Camera for Surveys.The observations suggest that the newly-discovered galaxies were very common nine billion years ago. However, it is a mystery why the newly-found dwarf galaxies were making batches of stars at such a high rate.
