THE BRAIN’S MASTER CLOCK

Daniel 2:21
“And he changeth the times and the seasons: he removeth kings, and setteth up kings: he giveth wisdom unto the wise, and knowledge to them that know understanding.”

 

Our bodies have many different rhythms. For example, your body temperature and your blood pressure cycle throughout the 24-hour day. Other body rhythms complete their cycle in 7 days or 28 days and so on.

Some bodily rhythms are controlled through the hypothalamus, some by the pituitary gland, but there are other glands that control the rhythms of other organs. This arrangement sounds sort of like standing in a room with hundreds of clocks ticking away. And to make matters worse, each clock goes off on its own time – none are set to the same time. It could be a confusing mess.

But now it has been learned that the brain has one master clock that coordinates all the other clocks in the body. This master clock goes by the initials SCN. It was once thought that the hypothalamus did this work. But the hypothalamus is just an assistant to the SCN. Together they turn out a bewildering array of chemical signals for the rest of the body so that everything keeps humming along in fine order.

So here we have one more example of the intricate and wise design of our loving Creator and how He leaves no detail of life to chance. If He can do this, He certainly wants you to bring all the details of your life to Him as well.

Prayer:
Dear Lord Jesus Christ, You teach me that my heavenly Father desires an even closer relationship with me, and that He is intimately involved in every detail of His creation. Teach me through Your Word, and help me to believe what You teach me. Amen.

YOUR MULTIPURPOSE EYE

Psalms 94:9 He that planted the ear, shall he not hear? he that formed the eye, shall he not see?

Scientists have learned that the eye is a multipurpose organ. They have long tried to figure out how our internal biological clock is set. This amazing clock is located in the brain and follows a period of almost exactly a day. It controls many of the body’s rhythms, so it’s important that it is properly set.

Scientists do know that the clock is set by light. They also know that your clock is not set by the rods and cones in your eye that see color and images. They had conclusively shown that the eye’s rods and cones have nothing to do with setting the clock. Several years ago, researchers bred mice whose eyes lacked rods and cones. As they shifted light periods, the mice still adjusted their biological clocks to the new periods. Now researchers are convinced they have found how our eyes adjust our biological clock after studying, of all things, the African horned frog. While studying the frog, scientists discovered a photoreceptor called melanopsin. This photoreceptor is found in the skin, eyes and brain of the frogs. They then decided to test for melanopsin in our eyes. They disco vered that a form of the photoreceptor is produced in the inner retina of our eyes. The rods and cones of our eyes are located on the outer retina. The human eye, and those of mammals, is a multi purpose organ!

The intricate and precise ways in which we have been made increasingly glorify our Creator as we learn more about how we have been made. Surely it takes more faith to believe that such an elegant system as our biological clocks evolved by chance.

WHY DID GOD GIVE US FINGERPRINTS?

Genesis 27:21 And Isaac said unto Jacob, Come near, I pray thee, that I may feel thee, my son, whether thou be my very son Esau or not.

Criminals who have been linked to a crime through their fingerprints may not be happy that they were born with a unique pattern of “wrinkles” on their fingertips. But we can all be glad that God gave us fingerprints because they greatly improve our sense of touch.

Scientists in France performed a series of experiments with artificial fingertips made of rubber-like sensors. They then compared the sensitivity between these grooved artificial fingertips and a smooth skin-like material to see if the grooved fingertips made a difference in the sense of touch. What they discovered surprised them. The grooved fingertips produced vibrations up to 100 times stronger than the smooth material when sliding against a slightly rough surface.

The researchers concluded that these increased vibrations provide us with a greater ability to detect textures. When rubbing your fingers across a textured surface, your fingerprints amplify vibrations that stimulate the nerve endings in your skin. This then allows us to identify objects by touch.

Knowing that we need our sense of touch to work from every direction, our Creator designed our fingerprints to appear in elliptical swirls. This loop design ensures that some ridges are always brushing perpendicular to a surface, no matter the orientation of our fingertips.

Such research may help scientists design prosthetic hands with enhanced tactile feedback. Once again, when science copies designs found in living things, it is copying the designs put in living things by their Creator, whether they recognize that fact or not!

Prayer:
Lord Jesus, thank You for all of my senses, including the sense of touch. Amen.

A QUESTION OF ORIGIN

Genesis 1:1 In the beginning God created the heaven and the earth.

Genesis 2:4 These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens,

Psalms 19:1-3 To the chief Musician, A Psalm of David. The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard.

 

A QUESTION OF ORIGINS

During the past century, much of the world has accepted the theory of Evolution as fact. Yet the molecules-to-man theory has no direct evidence to support it at all. Origins provides overwhelming evidence in favor of Creation.

The theory of Evolution has been applied to most scientific fields and this video thoroughly exposes the blind speculation and evolutionary bias in three of these areas of science including: Cosmology, Chemistry, and Biology .

This visually rich, full production reveals conclusive evidence that the universe and all life were created by a Supernatural Being, and that the God of the Bible is that Creator.
