French novelist Marcel Proust once fancifully described the smell as transforming my humble chamber pot into a bowl of aromatic perfume. But it seems he was in the minority as three in five people are unable to even detect the odour, according to a study published on Wednesday. From data on 6909 participants, 58 per cent of men and 61. 5 per cent of women had asparagus anosmia, or the inability to detect the smell, according to the results in the BMJ medical journal s Christmas edition, traditionally reserved for studies that are quirky but scientifically sound. Among this majority, researchers from the Harvard School of Public Health found 871 genetic coding variants, or SNPs, on genes associated with smell suggesting the inability is inherited. Professionals have long debated the cause
Although they are very different species, fish and dolphins (mammals) look similar. Their body shape is highly streamlined: both have fins and a tail. Evolution appears to have repeated itself in producing these two animals that are formed alike. Similar adaptations occur quite frequently, however, but none of them are due to "repeating evolution". When distantly related lineages such as fish, extinct reptiles such as ichthyosaurs, and mammals evolve so that they are superficially similar in external appearance, they are said to be converging, and the trend is called convergent evolution. ...

Letter from the Virginia Ratifying Convention to the New York Ratifying Convention, July 2, 1788 The United States Constitution went into effect in 1789. Ratification by nine states was needed for the Constitution to be adopted. The decision to ratify it was made by ratifying conventions from eleven of the thirteen states; North Carolina and Rhode Island initially refused to ratify the constitution. The two most important states that had not decided by June 1788 were Virginia and New York, and without them in the Union the country would have been divided into parts: New England, the mid-Atlantic states, and the southern states. In effect, the new system of government could not have functioned without Virginia and New York. The leading prospect for the president or the head of the
ANSWER: Abbreviating the word Christmas to Xmas does not 'cut Jesus short' as your Emailed question suggested. Before we explain this, let us first discover where the X in the abbreviation came from and then provide a little history The word for Christ in the Greek is Christos (which is Strong's Concordance #5547). In Greek, the twenty-second letter of their alphabet is written as X (the X of Xmas) and is pronounced CHI. It is the first Greek letter in the word for Christ. Many years ago, retailers realized they could save both space and costs by shortening the word Christmas to Xmas using the letter X to replace the letters Christ. After a few years of this practice, however, the religious community countered with the slogan that called for Christ's name to be put BACK into the holiday.
It is very difficult for most animals to find enough food in winters when the main source of food like insects or green plants is in short supply. Some animals solve this problem by hibernating. Hibernation is a deep sleep adaptation mechanism that helps such animals to save energy and survive the winter without consuming much food. Many physiological changes occur in the body of the animals during hibernations where the animal s body temperature drops and its heartbeat and its breathing slow down so that energy can be conserved. However, some animals such as skunks, raccoons and some chipmunks are light sleepers and are easily awakened. They may sleep during the most severe weather and wake to roam and eat during milder weather. Most hibernators prepare in some way for the winter. While
Evidence shows that many HIV infected persons access health care during the years before they are diagnosed, but they are not tested for HIV, in fact 1/3 of those who test positive are diagnosed late in the course of their disease when it is too late for them to get the full advantage of treatment. Antiretroviral Therapy (ART) is most effective if initiated before symptoms develop and will reduce the risk of developing opportunistic infections, HIV related cancers, and AIDS. HIV should be treated as a chronic disease that is managed over a person s lifetime. HIV screening is essential to prevention efforts. Those who are unaware of their infection are 3. 5 times more likely to transmit the virus to another person as compared to those who are aware of their infection. The 21% of those who
"Dream content changes as a woman's body changes," says Garfield. "Her dreams echo her changing condition and both her hopes and her fears about the coming child. " For instance, explains Garfield, during the, dreams about water and are quite common.

"The mother through water is also common and can relate to her identifying with the. " In the, dreams start to reflect the changes in the baby and the mother's
Unlike herbaceous plants, deciduous trees stand tall all winter, minus some important accessories-leaves. What trigger causes leaves to fall in the autumn? To understand why leaves fall off, it helps to first understand what the job of a leaf actually is. Plants and other photosynthesizing organisms have a very special talent. They can turn sunlight into food. It is a pretty neat trick that only photoautotrophs can do (photo=sun; auto=self; troph=feeder). In order for plants to make food energy, they need water, carbon dioxide (CO2) and sunlight. From this special combination, a plant is able to make its own food, in the form of glucose, a type of sugar. Plants then use the glucose as food energy to live and grow. In order to harvest sunlight energy, plants have a green pigment called
