Early creativity linked to teenage intelligence

A research conducted at the King’s College London has showed that differences in children’s drawings at ages 4 and 14 has an important genetic link that could give an idea about their intelligence levels.

Dr Rosalind Arden, lead author of the paper, MRC Social, Genetic and Developmental Psychiatry (SGDP) Centre, said that ‘The Draw-a-Child’ test was devised in the 1920s to assess children’s intelligence, so the fact that the test correlated with intelligence at age 4 was expected. Arden asserted that the correlation was moderate, but it did not mean that parents should worry if their child drew badly. Drawing ability did not determine intelligence, there were countless factors, both genetic and environmental, which affected intelligence in later life.

He explained that a child’s ability to draw stemmed from many other abilities, such as observing, holding a pencil, etc., and there was no ‘drawing gene’ in us. Arden added that drawing was an ancient behaviour, dating back beyond 15,000 years ago and that it was attempt to show someone else what was in their mind.
Parental neglect turns boys into aggressive adolescents

Young boys who are neglected by their parents may turn into violent adolescents, a new study has revealed.

The study indicated that while physical abuse was a considerable contributor to violent behaviour, physical neglect alone was an even stronger predictor of male adolescent violence than physical abuse, or even physical abuse and neglect combined.

William McGuigan, an associate professor of human development and family studies at Penn State Shenango, asserted that one of the problems with studying neglect was that it was an act of omission, rather than one of commission. McGuigan said it sounded somewhat contrarian, but the physical abuse might at least show that parents were paying some type of attention to the child. 
Violent video games culprits of childhood depression

A study conducted at the University of Texas Health Science Center at Houston School has suggested that kids who play violent video games might be at a greater risk of depression.

The study recorded significantly more depressive symptoms over the course of a year among fifth-graders from three US cities who reported playing high-violence video games for two or more hours a day, compared to those who reported playing low-violence video games for less than two hours a day.

Editor-in-Chief Brenda K. Wiederhold, Virtual Reality Medical Institute, Brussels said that one of the strengths of this study was its large and ethnically diverse sample.
FGF proteins found crucial in wound healing process

Researchers have recently found proteins that play a vital role in the wound healing process.

The paper’s senior author, David M. Ornitz, MD, the Alumni Endowed Professor of Developmental Biology, studies a group of proteins known as fibroblast growth factors, or the FGF family of proteins. 

FGF proteins are signaling molecules that play broad roles in embryonic development, tissue maintenance, and wound healing. They interact with specific receptor molecules, FGFRs, located on the surface of many types of cells in the body.

The study suggested that increasing FGF signaling in the body might help improve wound healing by increasing new blood vessel growth following an injury. 

Especially in those who have trouble healing, such as patients with diabetes-related foot ulcers. It was pointed out that human FGF2 has already been in clinical use as a topical spray in Japan for foot ulcers and similar wound healing purposes.

The research also suggested these FGF pathways are not involved with normal development and tissue maintenance, and any treatment boosting or inhibiting these signals would likely not affect healthy tissue.
