SYNTHETIC cells made by combining components of Mycoplasma bacteria with a chemically synthesised genome can grow and divide into cells of uniform shape and size, just like most natural bacterial cells.

There are 2 ways of culturing cells in the laboratory for in vitro experiments. The first is a liquid medium culture called suspension culture done in cell culture flasks, and the second is a semi-solid medium of culturing done in cell culture plates.

How do scientists study cells? Imaging techniques magnify organelles and track cells as they divide, grow, interact, and carry out other vital tasks. Biochemical or genetic tests allow researchers to study how cells respond to environmental stressors, such as rising temperatures or toxins.

When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.

Scientists can use stem cells, or tissues grown from them, to search for new drugs that improve their function or alter the progress of disease, as well as to test how drugs might affect different organs (for example, the liver or the kidneys), or how they might affect different people.

Human cloning is the creation of a genetically identical copy (or clone) of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins.

The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. When, and where, was human culture born? ”It’s the hot issue, and we all have different positions,” said Dr.

Man and woman created in the image of God implies that God has ownership over our lives and will one day justly pass eternal judgment upon us. Genesis 1:27: “So God created man in his own image, in the image of God he created him; male and female he created them.”

21 The Lord God made garments of skin for Adam and his wife and clothed them. 22 And the Lord God said, “The man has now become like one of us, knowing good and evil.

There are some interesting differences when we compare the pattern of brain growth in humans to chimpanzees, our closest living relatives. Both brains grow steadily in the first few years, but the shape of the human brain changes significantly during the first year of life.

A larger brain brings better cognitive performance. And so it seems only logical that a larger brain would offer a higher survival potential. In the course of evolution, large brains should therefore win out over smaller ones.

Summary: Using a large dataset and controlling for a variety of factors, including sex, age, height, socioeconomic status, and genetic ancestry, scientists found that people with larger brains rated higher on measures of intelligence and educational attainment.

In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. In other words, brain size accounts for between 9 and 16 percent of the overall variability in general intelligence.

Meditate. Just as you exercise to expand your muscles, you can meditate to increase the size of your brain. A 2000 study conducted by researchers at Harvard University found that meditation increases the size of the brain regions that are associated with focused attention, deep thought and memory.
