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

ISLAMABAD, Nov. 14 (Xinhua) -- Pakistan ranks the seventh in the world in terms of diabetes prevalence rate and over 7.1 million people in the country are diabetes patients, reported local media on Monday.Quoting a report by the World International Diabetes Federation, a local English newspaper "The News" said that every year 89,000 people die of diabetes in Pakistan and the number of diabetes patients in the country could hit 11.5 million by the year 2025 if proper measures were not taken.This would make Pakistan the world's fifth largest country in terms of its number of diabetes patients 14 years later, warned the report.At a seminar organized Monday in Islamabad to observe the World Diabetes Day which falls on Nov. 14, Dr. Abdus Salam from Shifa International Hospital, a private-run hospital in the capital city, said that every ten seconds, two people are diagnosed with diabetes and one person dies of diabetes-related causes.The average age of diabetes patients in Pakistan is one of the lowest in the world, said the report. In a bid to raise public awareness about the harmful effects of diabetes, various diabetes camps, scientific sessions, seminars and walks were organized across the country on Monday to mark the World Diabetes Day.In a message delivered on Sunday, Pakistani Prime Minister Yusuf Raza Gilani said that the World Diabetes Day draws attention to the lethality of the disease and underscores the need of preventive measures at individual and collective levels."Diabetes is a killer which is taking the life of one person out of every 800," said the prime minister, adding that "this disease hits people of all age groups, rich and poor alike without any discrimination."

BEIJING, Oct. 2 (Xinhua) -- Chinese archeologists have found evidence indicating that the mysterious ancient city of Loulan (Kroraina) once had highly-developed agricultural systems.Scientists from the Institute of Geology and Geophysics under the Chinese Academy of Sciences conducted remote sensing procedures, field investigations and sample testing in the area and found that there were once large tracts of farmlands in Loulan.The farmland featured regular and straight circumferences stretching for 200 to 1,000 meters as well as irrigation ditches running throughout, said Qin Xiaoguang, a member of the research team.Moreover, researchers found grain particles in the area's ground surface, which are very likely to be remains of crop plants, Qin said.These findings show that irrigation farming had been practiced in Loulan for at least 100 years, Qin said.Qin said they also found canal remains measuring 10 to 20 meters wide and 1.6 meters deep in the Loulan relics, indicating that the city, which is suspected of perishing in drought, was once rich in water resources.The ancient city was a pivotal stop along the famous Silk Road, but mysteriously disappeared around the third century AD.Previous historical records suggested that Loulan's economy was sustained by widespread agricultural activity, but no remains or other evidence had been found before the most recent discoveries.

BEIJING, Dec. 12 (Xinhua) -- A Foreign Ministry spokesman said on Monday that China welcomes the EU's new measures for coping with the European sovereign debt crisis worked out at the recently-concluded EU summit."We hope relevant measures can help stabilize the market, boost confidence in the market, stop the crisis from worsening, promote employment and economic growth, and push forward European integration," Foreign Ministry Spokesman Liu Weimin said at a routine press briefing.Last Friday at the summit in Brussels, EU leaders agreed on establishing a new "fiscal compact" based on inter-governmental treaties rather than the expected EU treaty changes. Britain opted out of the compact.Under the fiscal compact, member states will have to submit their draft budgetary plans to the European Commission, the EU's executive arm.As world's largest economy, the stable and healthy growth of the European Union and the Eurozone will be crucial to maintaining the momentum of recovery in the world economy, Liu said.China will maintain its support for EU integration, and continue to back the EU's efforts in combating the debt crisis in various ways, so as to jointly promote the stability of the international financial market and the recovery and growth of the world economy, he said."We are confident in Europe and the Eurozone, and believe that the EU has the ability and wisdom to resolve the sovereign debt crisis," Liu said.

WASHINGTON, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."
