WASHINGTON, April 5 (Xinhua) -- NASA and co-researchers from the United States, the Republic of Korea and Japan have found a new mineral named "Wassonite" in one of the most historically significant meteorites recovered in Antarctica in December 1969, the U.S. space agency said on Tuesday in a statement.The new mineral was discovered within the meteorite officially designated Yamato 691 enstatite chondrite. The meteorite likely may have originated from an asteroid orbiting between Mars and Jupiter. Wassonite is among the tiniest, yet most important, minerals identified in the 4.5-billion-year-old sample.The research team, headed by NASA space scientist Keiko Nakamura-Messenger, added the mineral to the list of 4,500 officially approved by the International Mineralogical Association."Wassonite is a mineral formed from only two elements, sulfur and titanium, yet it possesses a unique crystal structure that has not been previously observed in nature," said Nakamura-Messenger.In 1969, members of the Japanese Antarctic Research Expedition discovered nine meteorites on the blue ice field of the Yamato Mountains in Antarctica. This was the first significant recovery of Antarctic meteorites and represented samples of several different types.As a result, the United States and Japan conducted systematic follow-up searches for meteorites in Antarctica that recovered more than 40,000 specimens, including extremely rare Martian and lunar meteorites.Researchers found Wassonite surrounded by additional unknown minerals that are being investigated. The mineral is less than one-hundredth the width of a human hair or 50x450 nanometers. It would have been impossible to discover without NASA's transmission electron microscope, which is capable of isolating the Wassonite grains and determining their chemical composition and atomic structure."More secrets of the universe can be revealed from these specimens using 21st century nano-technology," said Nakamura- Messenger.The new mineral's name was approved by the International Mineralogical Association. It honors John T. Wasson, professor at the University of California, Los Angeles. Wasson is known for his achievements across a broad swath of meteorite and impact research, including the use of neutron activation data to classify meteorites and to formulate models for the chemical makeup of bulk chondrites.

TIANJIN, April 16 (Xinhua) -- As China tries to establish a universal medicare umbrella, its first move to offer treatment to all the hemophilia patients in the country is to know their population and where they are.China's national hemophilia information management center registered 7,980 cases nationwide since its establishment last year in a bid to provide reference for making national treatment policies and medicine production quota, said the center officials Saturday.Yang Renchi with the center and the Chinese Academy of Medical Sciences, said that the patient information database will help the government make hemophilia-related medical and social welfare policies, optimize resources and guide the manufacturing of drugs such as coagulation factor VIII.The information center, created by the Ministry of Health, is located in the Blood Diseases Hospital of the Chinese Academy of Medical Sciences in the port city Tianjin in north China.Hemophilia is a rare genetic bleeding disorder that prevents the blood from clotting properly, resulting in easy bruising and prolonged bleeding from trauma. Lack of treatment can lead to permanent disabilities or even death.China is estimated to have roughly 100,000 hemophilia patients."Be inspired; get involved in Treatment for All" is the theme for the 22nd World Hemophilia Day, which falls on Sunday, April 17."A necessary precondition for 'Treatment for All' is to know the clinical information and location of each case," said Yang, "and this is exactly what the information system does."In addition, China plans to establish hospital-based provincial hemophilia management centers within five years across the country to register and monitor patients and standardize disease diagnosis and treatment under the information system.SHORTAGE OF DRUGSBlood-derived coagulation factor VIII and recombinant coagulation factor VIII are two effective drugs which are vital for hemophiliacs. However, the drugs are expensive and produced in limited quantities, a difficulty which hundreds of thousands of hemophiliacs in China have to confront.According to Yang, the minimum dose of coagulation factor VIII for prevention of bleeding episodes is two international units (IU) per kg of weight a day. A 50-kg hemophilia patient needs at least 36,500 IU of factor VIII every year to prevent bleeding."Each IU of blood-derived coagulation factor VIII costs about 3 yuan(0.46 U.S. dollars) and the annual cost is almost 120,000 yuan. The recombinant one is almost twice the price," said Yang.Only four drug firms are qualified to manufacture blood-derived coagulation factor VIII in China. The national output in 2010 was 400,000 vials (200 IU per vial) which means 80 million IU for the entire country.Wu Runhui, a hematology specialist with the Beijing Children's Hospital, said that the minimum dose is only for the prevention of bleeding episodes which are required to keep the patient alive. For the hemophiliac to live a regular lifestyle, 3,000 IU per kilo a year is needed, which would cost half a million yuan a year."Even in the most developed countries, a hemophiliac cannot survive without supportive medical policies and social welfare system," said Wu.

BEIJING, Feb. 12 (Xinhua) -- A delegation of the Chinese People's Political Consultative Conference (CPPCC) left Beijing Saturday evening to visit Ghana, Rwanda and Mozambique.The delegation, led by Vice Chairman Li Zhaozhuo of the CPPCC National Committee, was invited by the Parliament of Ghana, the Rwandan Chamber of Deputies and the Parliament of Mozambique.

WASHINGTON, April 4 (Xinhua) -- New research from the University of Pennsylvania School of Medicine has revealed an increased incidence of major adverse cardiac events (MACE), such as heart attack, stroke, and cardiovascular death, in patients with severe psoriasis. The study results were reported Monday at the annual American College of Cardiology meeting in New Orleans.Psoriasis is a common inflammatory skin disease, and if severe, has been demonstrated to be a risk factor for cardiovascular disease. However, the degree to which psoriasis is associated with MACE has not been defined.In a cohort study analyzing data from a general practice research database, Lead author Nehal Mehta, director of Inflammatory Risk in Penn's Preventive Cardiology program, and colleagues reviewed the case histories of over 3,600 patients with severe psoriasis and 14,300 controls. They found that patients with severe psoriasis have a 53 percent increased incidence of MACE compared to the general population. They also found that having a diagnosed case of severe psoriasis confers an additional ten-year risk of six percent on MACE.Previous work from Mehta and colleagues found that the risk of death from cardiovascular disease increased by 57 percent in patients with severe psoriasis. In addition, the relative risk of death from cardiovascular disease was even higher in younger patients, who were as young as age 40.The researchers conclude that this new estimate of increased ten-year MACE may warrant more aggressive strategies for treatment of cardiovascular risk factors in patients with psoriasis.

SAN FRANCISCO, April 22 (Xinhua) -- Apple and Google collect smartphone users' location information as part of their race to build massive databases, The Wall Street Journal reported on Friday after analyzing data and documents.According to the report, security analysts with the newspaper found that Apple's iPhone and smartphones running Google's Android operating system regularly transmit users' locations back to the two companies respectively, which is part of their race to build databases capable of pinpointing people's locations via smartphones.A report by research firm Gartner indicated that the market for location-based services is expected to rise to 8.3 billion U.S. dollars in 2014 from the current 2.9 billion dollars.In the case of Google, a security analyst with The Wall Street Journal said an HTC Android phone collected name, location, signal strength of any nearby Wi-Fi networks, and a unique phone identifier every few seconds and transmitted the data to Google at least several times an hour."All location sharing on Android is opt-in by the user," Google said in a statement to technology blog site All Things Digital, in response to the concern that how Android system uses location information."We provide users with notice and control over the collection, sharing and use of location in order to provide a better mobile experience on Android devices. Any location data that is sent back to Google location servers is anonymous and is not tied or traceable to a specific user," said the statement.Worries on the iPhone tracking issue surfaced on Wednesday after two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data for extended periods of time.The researchers said starting on June 21 2010, after the release of iOS 4 mobile operating system, iPhones began logging and storing location information in a file, which shows the users' latitude and longitude and is timestamped to the second. They noted the information is not encrypted on the phone or on the iPhone backups made by iTunes and the file is also persistent, transferring itself to a new iOS device when the old one is replaced.They added they had no evidence that the file was being transmitted to Apple.On Thursday, U.S. congressman Edward Markey reacted angrily to the news in a letter to Apple CEO Steve Jobs, which is posted on Markey's official website.Markey asked Jobs to make a response within 15 business days or no later than May 12, saying "Apple needs to safeguard personal location information of its users to ensure that an iPhone doesn't become an iTrack."Apple has made no comment on the issue so far, but a letter it sent to U.S. Congress last July came under spotlight. In the letter, Apple said it collects Wi-Fi and GPS information when the phone is searching for a cellular connection and gathers the data to help build a "database with known location information."
