Monkey

A monkey is a member of either of two of the three groupings of simian primates. These three groupings are the New World monkeys, the Old World monkeys, and the apes. The New World monkeys are classified within the parvorder Platyrrhini, whereas the Old World monkeys (superfamily Cercopithecoidea) form part of the parvorder Catarrhini, which also includes the apes. Thus, methodically speaking, monkeys do not form a "natural group", in that the Old World monkeys are in fact more closely related to the apes than they are to the New World species. There are 264 known extant species of monkey. Because of their similarity to monkeys, apes such as chimpanzees and gibbons are often called monkeys in informal usage, though biologists don't consider them to be monkeys. Conversely, due to its size (up to 1 metre) the Mandrill is often thought to be an ape, but it is actually an Old World monkey. Also, a few monkey species have the word "ape" in their common name. Because they are not a single coherent group, monkeys do not have any particular traits that they all share and are not shared with the remaining group of simians, the apes.

Manhattan

Manhattan refers to both the Island of Manhattan and encompasses most of the Borough of Manhattan, one of the five boroughs of New York City. The viable, financial, and cultural center of the city, Manhattan has many famous landmarks, tourist attractions, museums and universities. It is also home to the control center of the United Nations and the seat of city government.The borough of Manhattan is coterminous with New York County, which is also the most densely populated county in the United States. Postal addresses within the borough are typically chosen as "New York, NY."Manhattan has the biggest central business district in the United States and is the site of most of the city's corporate headquarters and the New York Stock Exchange. Although its population is third biggest of the five boroughs, after Brooklyn and Queens, and it is geographically the smallest, Manhattan is the borough that many visitors most personally associate with New York City.

Heart cancer

Heart cancer is an very rare form of cancer of the heart. Heart cancer is separated into primary tumors of the heart and secondary tumors of the heart. Most heart cancers are benign of myxomas, fibromas, rhabdomyomas and hamartomas, although malignant sarcomas (such as angiosarcoma or cardiac sarcoma) have been well-known to occur. In a learning of 12,487 autopsies performed in Hong Kong seven cardiac tumors were found, most of which were benign. However, cancer can also reach to heart from other parts of the body. In addition the heart can be affected by handling for cancer in other parts of the body.

Cloud

The color of a cloud tells much about what is going on inside the cloud. Clouds form when comparatively warm air containing water vapor is lighter than its surrounding air and this causes it to rise. As it rises it cools and the vapor condenses out of the air as micro-droplets. These tiny particles of water are relatively densely packed, and sunlight cannot penetrate far into the cloud before it is reflected out, giving a cloud its characteristic white color. If the cloud is sufficiently large, and the droplets within are spaced far enough apart, it may be that a proportion of the light which enters the cloud is not reflected back out before it is absorbed This process of reflection/absorption is what leads to the range of cloud color from white through grey through black. For the same reason, the undersides of large clouds and heavy overcasts appear various degrees of grey; little light is being reflected or transmitted back to the observer.Other colors occur naturally in clouds. Bluish-grey is the result of light scattering within the cloud. In the visible spectrum, blue and green are at the short end of light's visible wavelengths, while red and yellow are at the long end. The short rays are more simply scattered by water droplets, and the long rays are more likely to be absorbed. The bluish color is evidence that such scattering is being produced by rain-sized droplets in the cloud.A more ominous color is the one seen commonly by severe weather observers. A greenish tinge to a cloud is produced when sunlight is scattered by ice. A cumulonimbus cloud which shows green is a pretty sure sign of imminent heavy rain, hail, strong winds and possible tornados. Yellowish clouds are rare, but may occur in the late spring throughout early fall months during forest fire season. The yellow color is due to the presence of smoke. Red, orange and pink clouds occur almost wholly at sunrise/sunset and are the result of the scattering of sunlight by the atmosphere itself. The clouds themselves are not that color; they are merely reflecting the long rays of sunlight which are predominant at those hours. The effect is much the same as if one were to shine a red spotlight on a white sheet. In combination with large, mature thunderheads, this can produce blood-red clouds.

Ganesha drinking milk again

NEW DELHI: In a re-run of the September 1995 frenzy when Ganesha statues were said to be drinking milk offered to them, devotees apparently thronged temples on Sunday night, making alike claims. This time, nevertheless, all idols were reported to be drinking milk.
This followed some reports received from additional parts of the country, particularly UP, earlier in the day. Shiv Mandir in Uttam Nagar and Shri Ram temple on Aruna Asaf Ali Marg in New Delhi witnessed a huge rush.
Said a Ram temple priest, "People observed that Ganesha is drinking milk around 8 pm, after which the word spread and thousands thronged the temple to try it out. Lord Ganesha drank milk from all. The crowd remained till around 11 pm."
Rationalists have explained the scientific cause behind this phenomenon, including surface tension, but faith and superstition always hit back. Said a devotee, "It was amazing.”
