WASHINGTON, Aug. 11 (Xinhua) -- The unique fossils of an adult plesiosaur and its unborn baby may provide the first evidence that these ancient animals gave live birth like mammals, according to a new study to be published Friday in the journal Science.The 78-million-year-old, 15.4-foot-long (4.7-meter-long) adult specimen is a Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles that lived during the Mesozoic Era.Dr. Robin O'Keefe of Marshall University in West Virginia and Dr. Luis Chiappe, Dinosaur Institute director of the Natural History Museum in Los Angeles County, have determined that it is the fossil of an embryonic marine reptile contained within the fossil of its mother.The embryonic skeleton contained within shows much of the developing body, including ribs, 20 vertebrae, shoulders, hips, and paddle bones.O'Keefe and Chiappe have also determined that plesiosaurs were unique among aquatic reptiles in giving birth to a single, large offspring, and that they may have lived in social groups and engaged in parental care.Although live birth has been documented in several other groups of Mesozoic aquatic reptiles, no previous evidence of it has been found in the important order of plesiosaurs."Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest," O'Keefe said."So the lack of evidence of live birth in plesiosaurs has been puzzling. This fossil documents live birth in plesiosaurs for the first time, and so finally resolves this mystery."

WASHINGTON, June 7 (Xinhua) -- Salmonella infections have not decreased during the past 15 years and have instead increased by 10 percent in recent years in the United States, according to a report released Tuesday by the Centers for Disease Control and Prevention (CDC).During the same time period, illnesses from the serious Shiga toxin-producing E. coli O157 have been cut nearly in half and the overall rates of foodborne infections have been reduced by 23 percent, the new Vital Signs report said.The report summarizes 2010 data from CDC's Foodborne Diseases Active Surveillance Network (FoodNet), which serves as America's report card for food safety by tracking whether nine of the most common infections transmitted through foods are increasing or decreasing."Although foodborne infections have decreased by nearly one-fourth in the past 15 years, more than one million people in this country become ill from Salmonella each year, and Salmonella accounts for about half of the hospitalizations and deaths among the nine foodborne illnesses CDC tracks through FoodNet," said CDC Director Thomas Frieden in a statement.In 2010, FoodNet sites, which include about 15 percent of the American population, reported nearly 20,000 illnesses, 4,200 hospitalizations and 68 deaths from nine foodborne infections. Of those, Salmonella caused more than 8,200 infections, nearly 2,300 hospitalizations and 29 deaths (54 percent of the total hospitalizations and 43 percent of the total deaths reported through FoodNet). CDC estimates that there are 29 infections for every lab-confirmed Salmonella infection.Salmonella, which is responsible for an estimated 365 million U.S. dollars in direct medical costs each year in the United States, can be challenging to address because so many different foods like meats, eggs, produce, and even processed foods, can become contaminated with it and finding the source can be challenging because it can be introduced in many different ways.In response to that challenge, the U.S. Food and Drug Administration, which regulates eggs, produce and many processed foods, has developed new rules for the egg industry to follow under its recently expanded regulatory authorities.The rate of E. coli O157 cases reported by FoodNet was two cases per 100,000 people in 1997 and, by 2010, had decreased to 0.9 cases per 100,000 people. The CDC credits the reduction in E. coli to improved detection and investigation of outbreaks, cleaner slaughter methods, better inspections of ground beef processing plants, and increased awareness by consumers and restaurant employees of the importance of properly cooking beef.

WARSAW, June 7 (Xinhua) -- Another patient suspected of Escherichia coli was admitted to hospital in Gizycko, northeastern Poland, on Tuesday, local media reported.On Monday Poland's first E. coli infection case was confirmed by tests conducted by the National Institute of Hygiene.Poland's first E. coli patient, a 29-year-old woman permanently residing in Germany and diagnosed with the bacteria, has been receiving treatment in a hospital in Szczecin in northwestern Poland for over two weeks.Two men suspected of E. coli have been hospitalized in Szczecin. They both had returned from Germany shortly before they fell ill. Another man suspected of E. coli was hospitalized in Ostroleka in central Poland also returned from Germany.A boy with haemolytic-uraemic syndrome (HUS), a disease characterized by hemolytic anemia caused by the E.coli patogenic bacteria, has been hospitalized in a Warsaw hospital.The E. coli epidemic originated in Germany. The Robert Koch Institute said the number of registered infections in Germany rose to 2,325 Tuesday, with those in other European countries still standing at about 100. The outbreak has killed a total of 23 people across Europe in the past month.

BEIJING, Sept. 14 (Xinhuanet) -- Scientists had discovered the fossils of a new species of ancient carnivorous fish, National Geographic reported Monday.The newly-found ancient fish, "Laccognathus embryi", is a 1.8-meter-long predator, which was "waiting to lunge out to grab whatever was in front of it," said study co-author Ted Daeschler, a vertebrate zoologist at the Academy of Natural Sciences in Philadelphia, the U.S..It had a jaw filled with sharp teeth that were 1.5 inches long, the Journal of Vertebrate Paleontology described.The fish lived in the Devonian period, 415 to 360 million years ago, which "was a fish-eats-fish kind of world," Daeschler said. "There was a real arms race going. If you didn't have good armor on your body, you were very vulnerable.""It's not just finding the animal - it's also placing the animal in its evolutionary crucible," Daeschler added.Its closest living relative is the lungfish which can survive in the drought, scientists said.Scientists hope the finding can help in their study on the revolution of fishes as well as other species.

CANBERRA, Aug. 3 (Xinhua) -- As many as a quarter of Australian women have experienced some form of assault or sexual abuse, and the higher proportion of the abuse, the higher rates of metal illness a woman tends to suffer from, a new study released on Wednesday found.Researchers from the University of Melbourne and the University of New South Wales conducted the study survey of 4451 Australian women aged 16 to 85. It looked at their experience of the four most common types of gender-based violence - sexual assault, rape, stalking and being badly beaten by their partners.About 15 percent of Australian women report sexual assault, while eight percent report rape, 10 percent said they have a stalker and eight percent report being beaten by their partner.It found strong links between those four types of violence and mental health problems including attempted suicide, posttraumatic stress disorder, panic attacks, depression, anxiety, and substance abuse.Among the women who experienced at least one form of violence, 30 percent had a mood disorder, nearly 40 percent an anxiety disorder, 23 percent were abusing substances and 15 percent were affected by posttraumatic stress syndrome.For the women who suffered higher levels of violence, the rates of anxiety disorders was 77 percent, 52 percent for mood disorders, substance abuse 47 percent and posttraumatic stress syndrome 56 percent.More than six percent of women experienced one form of violent had attempted suicide, compared to 35 percent of women who suffered at least three forms of violence.Public health expert Dr Susan Rees from the University of New South Wales' school of psychiatry, who led the research, said she is especially concerned about the suicide rate of women who are abused."What we found was that there's a high association or a strong association between exposure to gender-based violence and all the three broad classes of mental disorder - so that includes mood, anxiety, substance abuse - and a very high association with attempted suicide," she said in the report released on Wednesday."Women who've not experienced gender-based violence have about a 1.6 percent rate of attempted suicide and that increased to six percent of women who had experienced one type of gender-based violence."She said that gender-based violence was also associated with physical disability, impaired quality of life and a worsening of any existing mental disorders.Dr Rees called for the health care system, particularly psychiatric services, to work closer with women's services to improve support for victims of violence.She added that the federal government also need to underscore the importance of getting to the root cause of the violence against women by looking at attitudes towards women and gender inequality.The study was published in the Journal of the American Medical Association.
