The pissure of the sanctuary
Within “Petroleum swarm“Asher Radziner describes how oils are the habitats of sea species and whether they should leave the oil to be left after.
I have been an avid diver and pigeons for years in oil holes. I have to admit that these were some of my most memorable divers. These rowing offers a sanctuary for the rest of his life, basically an oasis in the Ocean desert. Small, if necessary, life would be there if it is not for these structures. Taking the taking would destroy a well-established ecosystem, not mentioning that doing this would cost a lot of money.

Colorful past
I had fun “Map color Conundrum“(Mathematics), Jack Murtagh has an overview of the historical discussion of the four-color theorem. Kenneth Appel and Wolfgang Hoken didn’t consider it as a recent word. In the 1940s book Apologies for mathematicianGH Hardy mathematician mathematicians expressed: “Beauty is the first test: there is no permanent place in the world for ugly mathematics.” I wait for more elegant evidence.
Of course, Martin Gardner published a famous “anti-rebellion” of the four-color theorem at American scientific Returned in April 1975.

Murtagh replied: The waters are in good company, with many mathematics that are waiting more elegant evidence of the four-color theorem. In terms of Gardner’s publication: In 1975, the April, Gardner played April stupid April, played a year in 1975 American scientific Mathematical column games. He published a map with 110 regions and claimed that only four colors could not be colorless, so it was a four-color conjecture. Of course, the map had a four-color scheme (like all maps, now we know); It was difficult to find. Gardner recognized the support of the Mathematician William McGregor for Hoax and July 1975 column.
Health Anxiety
As a psychologist, I appreciated the attention of Joanne Silberners in a situation used so often to minimize and reject people’s concerns “Severe hypochondria toll. “But I think it’s very important in the article that are not discussed directly in the article.
Daniel smaller Rehoboth Beach, Del.
After four decades as an internative, I saw a lot of people with Hypochondria and I have struggled to provide a proper treatment plan for these complicated patients. The article refers to a book, how the author described the one of the hospital tests, all had normal results and many of these symptoms were side effects of a drug over their insistence. There is a tour for this type of story.

Whales and carbon
I was fascinated “Buried in the sea“Jaime B. Palter proposed engineering proposed to promote carbon dioxide sequencing. I also read the” wonderful engineering of whales, which promotes the growth of phytoplankton. In addition to providing more food for larger animals, it is a higher amount of phytoplankton Glue in the atmosphere2. When these organisms die and sink in the floor of the ocean, they take carbon with them. It seems to protect whales’ populations and refunding to their historical numbers can be the best bet for our future.
Evelyn wiebe-Anderson Arcata, Caliph.
Poster responses: It is an attractive idea for restoring whaling populations, for most of the time he reinforced the ocean and return to his situation before degrading the ecosystem. However, there is no direct evidence, however, that it may be significant as a method of storing more carbon ocean. Scientists have tried Calculate how many additional carbon sequencings can provide whale restore (Directly directly, such as carbon in whaling carcasses and indirectly, such as stimulation of fitoplankton growth).
Direct pathways on pathways do not indicate climate-relevant scales, although there would be deep uncertainty, especially about indirect pathways, understanding future research to understand and quantify better. Fortunately, our oceans can have a cultural and economic value that more sustainable ecosystems and restoration faces carbon.
Galaxy brand
I have to agree with Phil Plait “Milkomeda” is a terrible name in favor of the future fusion of milk and Andromeda galaxies “Dairy path fate“(Universe).” Andromeway “would also be worse, and it’s on the right track. I think a snappier name would be better, which would make it better and the tongue would be greater,” Andy. “

“Undo the nerve vagina“In January 2017, in January 2017, he described the study of people with 2017 treatment, with 67.6% of the vagus nerve stimulation found symptoms. This result refers to a drop of 50 or more.
