IQ changes in teens as brain changes, study finds

Here's an interesting article that I want to share with you guys about IQ and brain.

here's the brief//

Wellcome Trust Centre for Neuroimaging at University College London has found that IQ can change in teens as the brain structure changes. They experimented with MRI scanning and saw how both verbal IQ and nonverbal IQ changes. Verbal IQ depends on the gray matter density and volume in a portion of the left motor cortex. Nonverbal depends on the gray matter density in anterior cerebellum which is related to the head movement.

Supplament reduces muscle loss in horses

Austrian researchers have found that a supplement of amino acids and proteins is able to prevent muscle breakdown in horses after exercise. This supplement is to help so that horses muscles do not fatigue as much after a race or intense exercise.

Potential Cure for Age-Related Muscle Loss

Doctors announce that they may have found a way to prevent age-related muscle weakness. By taking a drug, elderly people can slow the leaking of calcium from their muscles and improve function. It is believed that if the drug is taken while still relatively young, say 50 years old, age-related muscle loss could be prevented altogether.

Scientists Create Glowing Cats Using Modified Gene

Scientists in South Korea have cloned cats so that when they are exposed to ultraviolet rays, they will glow red. They feel it displays that other genes can be inserted and distorted in the course of cloning, which they believe is the gateway to the development of treatments for genetic diseases in humans and cats alike. In turn, this could lead to an easier and less painful life for one who deals with a genetic disease.

Scientists Reveal Cloning in Embryonic Stem Cell Research

This article highlights the discovery by New York genetic scientists who used cloning technologies to produce embryonic stem cells with three sets of chromosomes. There are obvious ethical discrepancies behind this, and many people are upset that the scientists created an ‘abnormal human life’. However, as of right now the cells are unusable for laboratory studies due to their mutations.

Study Maps Disease-linked Gene Variants

A study has found evidence that diseases linked to genes may alter regulating gene activity rather than altering the gene itself.  Scientists have found many diseases associated with genetic alterations but have not been able to find how the variation leads to the disease.
