Secrets of the human finger

>> Senin, 18 Januari 2010


Ring finger length ratio have long been considered as a good and bad. Recent research shows a finger to show aggressiveness.

The study was conducted regarding the child's exposure to testosterone is running fast and the ratio of finger.

Scientists studied 241 boys aged 10 to 17 years in the competition which was held in Qatar. Children with a circle is longer fingers faster in 50-meter dash.

"They were very fast at the beginning and be able to maintain performance," said John Manning, researchers at Southampton University who led the study.

Long fingers can indicate the aggressiveness in men but not in women. Children with long finger circle indicates good math test. While the index child's long fingers, good in reading and writing lessons.

While research in the journal BMJ 2006 to find the relationship between finger ratio and the nature of athletic women associated with hormone levels. People who ring finger is longer at high risk of osteoarthritis.

In the 2004 study in the American Journal of Human Biology reported, the proportion of people who are not symmetrical body such as a foot or larger ears, easy to show an aggressive nature when provoked.

"Factors like poor health, alcohol or cigarettes during pregnancy can cause the body that are not symmetrical," said Zeynep Benderlioglu researchers from Ohio State University.
"Conditions that affect the development of the central nervous system is involved in impulse control and aggressiveness. Although asymmetry does not cause aggressiveness, but the two things that seem related to the child," he said.

Privilege of Bee

>> Sabtu, 02 Januari 2010


Talk about bees, we will remember with a nest of bees and how they work well in the dark. They communicate through scent, vibration and physical interactions with other bees and more important, bees can recognize and react to pheromones (chemicals released by the bees). In the wild, honeycomb protection system which has a very good to keep bees in order to avoid environmental threats.

Inside the beehive, there are:
Queen bee (queen-bee)
Male bees (drones)
Worker Bees
- Bees nurses (nurse bees)
- Bees seeker (scout bees)
- Bee collectors (collector bees).

Phase egg
(3 days)

The queen laid an egg at the bottom of each cell. Position in the middle of the egg cell with one end attached to the bottom cell.
Phase Larvae
(6 days)

When the larvae hatch from eggs, larvae for 3 days were given royal jelly is produced from glands located in the head nurse bees.
Phase Pupa
(12 days)

The cells of each larva was then covered with wax for 12 days. After 21 days, an adult worker bees will hatch.

Queen Bee [Queen Bee]
In each hive, there will be only one queen bee among bee colonies that amounted to 80.000 tails. Genetically, the queen is responsible for its characteristics contribute to the other bees in the hive there. Therefore, there are bees in the nest, is certainly "formed from the same basic elements" with the queen bee.

Queen Bees

* Eating royal jelly throughout her life.
* Life is 40 times longer than worker bees, approximately 4 to 6 years.
* Grew 40% larger than worker bees.
* Eggs (thousands) per day.
* On the sexual
* It takes 16 days to grow



Worker Bees

* Eating royal jelly only on the first day of the 3rd larval phase.
* Only live for several weeks, an average of up to 50 days.
* Having a smaller body of the queen bee.
* Not in production / sterile
Not sexually active
* It takes 21 days to berkemban

Nurse bees [Nurse Bee]
Nurse bees are worker bees queen bee special treat and her children or larvae. They are responsible for producing royal jelly, and to feed the queen with royal jelly, bee pollen and honey.

Bees Seeker [Scouts Bees]
The bee is a worker bee seekers who are looking for sources of pollen, nectar and propolis. When they find the best food source, they will return to the nest and the bees inform collectors. Then, the bee collector went to collect the food.

Bee collector [Collector Bees]
When collecting pollen from the flowers, bees collecting only will visit the same type of flower pollen out until all accrued. At the time the bees collect pollen, it is also mixed with a little honey from her mouth and then forming clots that pollen will be stored in a bag found at the foot of bees.

Interesting facts! Beekeeper put tool called "pollen trap / trap pollen" around the hive entrance. Pollen trap consists of several lines of fine wire which aims to narrow the entrance of the bees that made some stored pollen clouds at the foot of the bees fell. After the number of pollens have accumulated enough, the farmer will move the net into another hive periodically.

Collecting bee sucking nectar from the flowers with their long tongues. They only visited the flowers of the same species in a single round of collection, to ensure that the collected nectar derived from a common source.

Nectar collected and stored in the open honey cells. These cells will remain open until the nectar evaporates and forms a viscous liquid honey and ripe.

Male bees [drones]
Male bee is the only male bees in the hive there and only served to fertilize the queen bee. Sixteen days after the new queen bee is born, he flew to the male bees that have been waiting for his arrival. After fertilize the queen, drones are then die.
