The Beehive Cluster (also known as Praesepe (Latin for "manger", "cot" or "crib"), M44, NGC 2632, or Cr 189), is an open cluster in the constellation Cancer. One of the nearest open clusters to Earth , it contains a larger population of stars than other nearby bright open clusters holding around 1,000 stars .

A cancer cluster is a disease cluster in which a high number of cancer cases occurs in a group of people in a particular geographic area over a limited period of time. [ 1 ] Historical examples of work-related cancer clusters are well documented in the medical literature.

The epidemiology of cancer is the study of the factors affecting cancer, as a way to infer possible trends and causes. The study of cancer epidemiology uses epidemiological methods to find the cause of cancer and to identify and develop improved treatments. This area of study must contend with problems of lead time bias and length time bias ...
An estimated 550,000 people live in the triangle of death. The annual death rate per 100,000 inhabitants from liver cancer is approximately 38.4 for men and 20.8 for women in this area, as compared to the national average of 14. The death rate for bladder cancer and cancer of the central nervous system was also higher than the national average. [5]
The bee genome contains versions of some important mammalian genes. The complete genome of Apis mellifera has been sequenced and consists of 10,000 genes with approximately 236 million base pairs. The size of the genome is a tenth of the human genome. [2] The Western honey bee gene sequence showed 163 chemical receptors for smell but only 10 ...
The bees cannot fly, and often crawl on the ground and up plant stems. In some cases, the crawling bees can be found in large numbers (1000+). The bees huddle together on the top of the cluster or on the top bars of the hive. They may have bloated abdomens due to distension of the honey sac. The wings are partially spread or dislocated.
