St. Petersburg: White Nights calling

St. Petersburg: White Nights calling Whoever called New York “the city that never sleeps” had clearly never been to St. Petersburg in the summer. The Russian metropolis, which will host seven matches at next summer’s FIFA World Cup, is bathed in almost perpetual daylight between May and June. If New York dances in the dark, St. Petersburg does a summertime shimmy without dimming the lights. Developed in the early 18th century under the watchful eye of Peter the Great, the city was home to Tchaikovsky, Pushkin and Dostoyevsky, helping it quickly grow into Russia’s cultural capital.

Galaxies are like the building blocks of the universe, they contain a huge number of stars, something like 100 billion at a count. Galaxy groups can have three to 20 galaxies, the richest systems are called clusters (like the Virgo cluster) which can have several hundred galaxies. Superclusters are clusters of clusters. They can have as few as two clusters, and superclusters with two to four clusters are common. Saraswati has 42. Within superclusters, clusters are connected by filaments and sheets of dark matter with galaxies embedded in them. It is supposed that the galaxies are born in the filaments and then migrate towards the intersection of the filaments where they are assimilated into clusters. What are superclusters? These are the largest coherent structures seen in the universe. Firstly there are clusters of galaxies together with associated gas and dark matter. Large groups of such clusters, ...

British baby Charlie Gard to be evaluated by US doc

British baby Charlie Gard to be evaluated by US doc Baby Charlie Gard, the 11-month-old with a rare, terminal medical condition who has been the center of an ongoing legal battle, will be evaluated by a doctor from the United States. Charlie will be examined early next week, in London, by Dr. Michio Hirano, a neurologist at New York’s Columbia University Medical Center. Hirano is developing an experimental therapy that has been used on at least one American patient with a similar but less severe mitochondrial disease. He specializes in myopathies and other neuromuscular diseases. Charlie was born in August with mitochondrial DNA depletion syndrome, a progressive disease that causes muscle weakness and loss of motor skills, leaving those who have it unable to stand, walk, eat, talk and eventually breathe. Charlie will die from his illness, his doctors have said. His parents, Chris Gard and Connie Yates, successfully raised money in hopes of bringing their son to the US for an experim...
