Marine monster mystery on South Carolina beachWritten By Benjamin Radford-Published March 29, 2012-Discovery News
A bizarre creature that washed ashore last week in Folly Beach, S.C., sparked speculation in the area and on the Internet that a dead sea monster might have been discovered. The tan-brown animal with greenish patches was strange enough, but what really baffled beachgoers was its massive size and the dinosaur-like bony plates on its sides. It's not clear just how long it was, but photos suggest it exceeded 10 feet. Like many washed-up carcasses it carried both a salty stench and an air of mystery. Speculation ran rampant, with commenters suggesting that the creature was everything from a dinosaurian sea monster to a toxin-spawned mutation to a chupacabra. Scientists, however, were somewhat more skeptical. |

Dive to ocean bottom was like trip to 'another planet and back,' Cameron saysPublished March 26, 2012-Associated Press
In James Cameron's fantasy films, like "Avatar" and "The Abyss," the unexplored is splashed in color and fraught with alien danger. But on his dive to the deepest place on Earth, reality proved far different: white, barren and bland.Yet otherworldly -- and amazing. "I felt like I literally, in the space of one day, had gone to another planet and come back," Cameron said Monday after returning from the cold, dark place in the western Pacific Ocean, seven miles (11 1/4 kilometers) below the surface. "It was a very surreal day." Cameron is the first person to explore the deepest valley in the ocean since two men made a 20-minute foray there more than half a century ago. He spent about three hours gliding through the icy darkness, illuminated only by special lights on the one-man sub he helped design. That was only about half as long as planned because his battery ran low. |

Is light now slower than a neutrino?
Now it seems that Einstein’s six-month nightmare may be over. I am not so sure about it.

James Cameron Now at Ocean's Deepest Point
Explorer-filmmaker reaches Mariana Trench on deepest ever solo sub dive.
At 5:52 p.m. ET Sunday (7:52 a.m. Monday, local time), James Cameron arrived at the Mariana Trench's Challenger Deep, members of the National Geographic expedition have confirmed. His depth on arrival: 35,756 feet (10,898 meters)—a figure unattainable anywhere else in the ocean. Reaching bottom after a 2-hour-and-36-minute descent, the National Geographic explorer and filmmaker typed out welcome words for the cheering support crew waiting at the surface: "All systems OK."
Folded into a sub cockpit as cramped as any Apollo capsule, the National Geographic explorer and frilmmaker is now investigating a seascape more alien to humans than the moon. Cameron is only the third person to reach this Pacific Ocean valley southwest of Guam (map)—and the only one to do so solo. |

Whooping cough evades vaccine
The study found that Australia's prolonged whooping cough epidemic has been predominantly caused by the new strain of the disease. |
Australia’s prolonged whooping cough epidemic has entered a disturbing new phase, with a study showing a new strain or genotype capable of evading the vaccine may be responsible for the sharp rise in the number of cases. A team of Australian scientists, led by the University of New South Wales (UNSW), believe this emerging new genotype (called prn2-ptxP3) of the Bordetella pertussis bacterium may be evading the protective effects of the current acellular vaccine (ACV), and increasing the incidence of the potentially fatal respiratory illness, according to the study published in The Journal of Infectious Diseases.
The new genotype also has been detected in other countries, suggesting it has the potential to spark epidemics elsewhere and should be closely monitored, the researchers warn.
“The prolonged whooping cough epidemic in Australia that began during 2008 has been predominantly caused by the new genotype of B. pertussis,” said one of the study authors, Associate Professor Ruiting Lan, of the UNSW School of Biotechnology and Biomolecular Sciences.
“The genotype was responsible for 31% of cases in the 10 years before the epidemic, and that’s now jumped to 84% – a nearly three-fold increase, indicating it has gained a selective advantage under the current vaccination regime.
“The vaccine is still the best way to reduce transmission of the disease and reduce cases, but it appears to be less effective against the new strain and immunity wanes more rapidly. We need to look at changes to the vaccine itself or increase the number of boosters,” Associate Professor Lan said.
Last year about 38,000 cases of the life-threatening disease were reported nationally, despite Australians having a relatively high vaccine uptake.
The authors said the increase in the number of whooping cough notifications may be partly due to recent improvements in diagnostic tests, which means that mild or atypical cases in older children or adults are now more likely to be correctly identified. However, this does not explain the marked increase in hospital admissions, especially of very young children who are not fully immunised, in whom the diagnosis is much easier.
Associate Professor Lan's laboratory team – led by postdoctoral research associate Dr Sophie Octavia – analysed close to 200 samples of the B. pertussis bacterium, collected from 2008 to 2010 over four states, NSW, Vic, SA and WA.
The team worked closely with researchers from the Centre for Infectious Diseases and Microbiology at Westmead (A/Prof Vitali Sintchenko and Prof Lyn Gilbert), Women's and Children's Hospital, Adelaide (Dr Andrew Lawrence), Princess Margaret Hospital for Children, Perth (Dr Tony Keil); and Microbiological Diagnostic Unit Public Health Laboratory, The University of Melbourne (Dr Geoff Hogg).
The findings suggest that while the current vaccination remains effective against most forms of whooping cough, its use could be contributing to the emergence of new and potentially more dangerous clones, Associate Professor Lan said.
First introduced in Australia in 1997, the ACV vaccination replaced the whole-cell vaccine (WCV), due to concerns about the latter’s side-effects.
“The whole cell vaccine contained hundreds of antigens, which gave broad protection against many strains of B. pertussis," said Associate Professor Lan. "But the acellular vaccine contains only three to five antigens.
“If the ACV is less effective against these new strains, we need to ask what other strategies can be used to combat the epidemic, which is ongoing."
There has been growing concern among public health officials about the rising incidence of whooping cough in Australia. The death rate for babies under the age of six months who catch pertussis is one in 200, according to NSW Health, which says adults and adolescents are at particular risk of contracting the disease and can pass it on to babies who are too young to be immunised.
In NSW, vaccinations are routinely given to infants at two, four and six months. The first dose can be given as early as 6 weeks of age. Boosters are needed at age four and again in high school. NSW Health also recommends that new parents and carers of young infants receive boosters.
