Human Brain Evolution Triggered By Duplicate Gene
2012-05-04 08:21:12

Brett Smith for Redorbit.com Scientists may have just found a ℠missing link´ in the form of a partial, duplicate gene that appears to be responsible for human brain development - the most distinguishing characteristic of our species. The genetic variation occurred in man´s ape-like ancestor about two or three million years ago, according to a pair of studies published online in the journal Cell. A team led by researchers at the Scripps Research Institute found that a...

A research team at Karolinska Institutet in Sweden has succeeded in describing the structure and function of the outermost layer of the skin — the stratum corneum — at a molecular level. This opens the way not only for the large-scale delivery of drugs via the skin, but also for a deeper understanding of skin diseases. "You could say that we've solved the puzzle of the skin barrier, something that has great potential significance for dermatology," says principal investigator...

A new study presented today at the International Liver Congress 2012 indicates the potential for gallbladder tissue (which is routinely discarded from organ donors and surgical interventions) to be a highly available candidate source for multipotential stem cells. Biliary tree stem/progenitor cells (BTSCs) have previously been identified in the glands of normal adult human extrahepatic bile ducts and been shown to generate in vitro and in vivo mature cells of the hepato-biliary and...

UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness and Alzheimer´s disease In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease. Published April 15 in the advance online edition of Nature Genetics, the study also uncovers new genes that may...

Discovery of organized, 3-D grid lays the groundwork for future investigations How do you build a brain? In the March 30 issue of Science a team of investigators presents a surprising answer, reporting their discovery of a remarkably simple organizational structure in the brains of humans and other primates. Employing sophisticated mathematical analysis of advanced imaging data, they found that the pathways carrying neural signals through the brain are arranged not in a disorganized tangle...

Neural networks of the brain can easily influence each other One cup or two faces? What we believe we see in one of the most famous optical illusions changes in a split second; and so does the path that the information takes in the brain. In a new theoretical study, scientists of the Max Planck Institute for Dynamics and Self-Organization, the Bernstein Center Göttingen and the German Primate Center now show how this is possible without changing the cellular links of the...

The work advances understanding of how memories form and offers new insight into disorders such as schizophrenia and post traumatic stress disorder Scripps Research Institute scientists and their colleagues have successfully harnessed neurons in mouse brains, allowing them to at least partially control a specific memory. Though just an initial step, the researchers hope such work will eventually lead to better understanding of how memories form in the brain, and possibly even to ways to...

Allen Donates $300 Million To 'Brain Observatory'
2012-03-22 05:11:16

Microsoft co-founder Paul Allen has donated $300 million in order to create a center that will study the brain and learn more about exactly how the human mind works, the Allen Institute for Brain Science announced Wednesday. The latest donation brings the amount of money that the 59-year-old businessman, investor and philanthropist has invested in the institute which was named in his honor to $500 million, Forbes staff writer Matthew Herper said. According to Herper and the Wall Street...

Liver
2013-04-30 14:18:06

The liver is the organ in charge of processing, neutralizing and excreting certain secretions for the metabolic processes. Formation and Orientation The liver is considered to be both the largest internal organ and the largest gland in the human body. It is situated just below the diaphragm, to the right of the stomach and on top of the gallbladder. There are two ways blood can travel to and from the liver: the hepatic artery and the portal vein. The hepatic artery carries blood solely...

Esophagus
2013-04-30 13:37:01

The esophagus is the muscular tube that is located between the pharynx and the stomach that aids in digestion during swallowing. Formation and Orientation The esophagus is composed of four separate layers; the mucosa, submucosa, muscularis externa and the adventitia. The mucosa includes the stratified squamous epithelium, lamina propria and muscularis mucosae. The submucosa houses the esophageal glands and connective papillae. The muscularis externa is composed of three sublayers The...

Ovaries
2013-03-05 14:55:04

The ovaries are the two reproductive female organs where the eggs are produced. These are parallel to the testes in men. Formation and Orientation Each ovary is the size of an almond and is located on one side of the pelvis before the ureter and internal iliac artery but after the external iliac artery. They are attached to either side of the uterus. They are connected and release eggs to fallopian tubes, though not attached, monthly during the menstrual cycle. They also produce...

Skin

Skin is the outermost organ that protects and incases the tendons, ligaments, bones, muscles, etc. It is also the largest organ of the human body. Formation and Orientation Healthy skin consists of vitamins A, C, D and E, but in all skin, there are melanocytes which produce mesodermal cells. These cells allow for the absorption of UV rays. There are five main pigments that provide color in the skin’s many levels. Although not found in the skin, Oxyhemoglobin is found in the blood,...

Appendix

The appendix is a dead-end tube like structure, ranging from 2 to 20 cm, that spans off the cecum of the colon. It is attached to the lower part of the large intestine. Formation and Orientation The appendix can be found in many mammals including marsupials, euarchontoglires (rodents) as wells as humans of course. It is also an organ that forms in the embryotic stage during pregnancy. McBurney’s Point, the point that is one-third the distance from infront and above the spinal cord...
