 Questions about the human cells:

The body of an adult contains about 50 million cells.

Three billion cells die every minute. Do not worry, most are renewed ….

The egg is the largest human cell, can be seen without a microscope.

Each tissue is formed by similar cells with a specific function.

Some small cells live only three days, while a brain cell can last a lifetime.

Red blood cells are the only cells without nucleus, carry oxygen and live about 120 days.

The cells multiply and divide to enable growth. The faster divisions occur in the fetus inside the mother.

Cancer is uncontrolled growth to cells that produce tumors.

All beings there are only two cells: an egg and sperm.

Neurons are the cells longer, some may reach over a meter.

If all verifications cells together could reach a length of 1000 km.

We have over 200 types of cells with specials functions.

The National Association of Spain OI Glass Bones (AHUCE), member organization ofCOCEMFE celebrates the World Day of Osteogenesis Imperfecta (OI), May 6,organizing and supporting various activities in different parts of Spanish territorycentered in this rare disease.
The disease is also known as brittle bone.
The origin of the World Day of OI is in Australia two years ago. The Osteogenesis Imperfecta Society of Australia considered positive to have a day on the calendar to do what the Anglo-Saxon world called “Awareness” (consciousness / awareness). Was launched through social networks in 2010. And the truth is that the idea has caught onstrongly worldwide.

May 2, 2012: The full Moon has a reputation for trouble. It raises high tides, it makes dogs howl, it wakes you up in the middle of the night with beams of moonlight stealing through drapes. If a moonbeam wakes you up on the night of May 5th, 2012, you might want to get out of bed and take a look. This May’s full Moon is a “super Moon,” as much as 14% bigger and 30% brighter than other full Moons of 2012.

The scientific term for the phenomenon is “perigee moon.” Full Moons vary in size because of the oval shape of the Moon’s orbit. The Moon follows an elliptical path around Earth with one side (“perigee”) about 50,000 km closer than the other (“apogee”). Full Moons that occur on the perigee side of the Moon’s orbit seem extra big and bright.

Such is the case on May 5th at 11:34 pm Eastern Daylight Time1 when the Moon reaches perigee. Only one minute later, the Moon will line up with Earth and the sun to become brilliantly full. The timing is almost perfect.
