The maps are the latest to be compiled in over two decades and provide a higher resolution picture of the ocean bottom revealing features not seen in previous versions. The study appears in the journal Science.

The U.S. Center for Disease Control and Prevention says EV-D68 (related to the common cold) is a mild to severe upper respiratory illness that can cause wheezing and coughing and in some cases even more severe symptoms can develop. Some patients can be treated with a nebulizer but others - such as those afflicted with asthma - can develop even more dangerous conditions. In one reported case, an infected child's lungs were disturbed to such a degree, he had to be placed on a blood oxygenator.
The outbreak is affecting mostly school-aged children because they haven't yet built up their immune systems like adults have. And even previously healthy children are getting sick. Between 2009 and 2013 the CDC reported only 79 cases of EV-D68, but already this year there have been more cases confirmed than in any previous year.
The illness can be spread through aerosol transmission via coughing or sneezing or by direct contact with a person or surface containing the virus. The best prevention against the virus is for adults and children to wash their hands regularly.

The Arecibo radio telescope - located in the karst hills of Puerto Rico - has detected the same "fast radio bursts" (FRBs) coming from somewhere beyond the Milky Way. The FRBs, also known as "Lorimer bursts" are extremely short in duration occurring about every 10 seconds. The exact source of these FRBs is still up in the air - so to speak - but the new study indicates that at least they aren't coming from anywhere on Earth.
"Our result is important because it eliminates any doubt that these radio bursts are truly of cosmic origin,” said research team member, Victoria Kaspi, an astrophysics professor at McGill University in Montreal. "The radio waves show every sign of having come from far outside our galaxy – a really exciting prospect."
But what the space noises are exactly remains a mystery. Speculation includes all sorts of strange goings-on including evaporating black holes, a neutron star cannibalizing another neutron star, or magnetic pulses from magnetars, bizarre neutrons stars possessing super-powerful magnetic fields.
The study's co-author, James Cordes, a professor of astronomy at Cornell University posits that they could be "bursts much brighter than the giant pulses seen from some pulsars".
The study appeared in the July 10 issue of The Astrophsyical Journal.

Only the edge of the frill on back of the skull was visible when Currie first came upon it, but eventually he dug out a nearly complete, articulated specimen. The only bones missing were the dinosaur's front legs.
Currie is professor of Dinosaur Paleobiology at the University of Alberta, in Edmonton, and now, after three long years of lab preparation, he and his staff are proudly showing off their prize dinosaur and getting it ready to put on display at the U of A Museums’ Galleries starting February 6th. "Baby" as the dinosaur is affectionately called, is the most complete baby ceratopsian dinosaur in the world.
