Scientists discover that three overlapping signals in embryo help get the backbone right

...mportant in preventing the premature fusion of the bones in the skull, and thus may be critical to allowing the brain to grow larger after birth. All of these findings are from mice or amphibians, but the researchers say that the same is almost certain to be the case in humans. "One of the things that's b...

Increased risk of osteoporosis associated with gene that one in five people have

...estrogen and is associated with low density in the bones of the hip. The study will be reported in the February issue of the Journal of Bone and Mineral Research and is available online. The gene, named CYP1A1, makes an abundant enzyme that detoxifies foreign substances and also breaks down estrogen as ...

Potential treatments for neurofibromatosis

... spots on the skin, enlargement and deformation of bones and curvature of the spine (scoliosis), and in many instances, learning disorders. Occasionally, tumors may develop in the brain, on cranial nerves, or on the spinal cord. However, a rare form of the disease occurs in infants and young children, wit...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

...at glands. It also seems to control the shape of - bones in the forehead and nose. Now, Kingsley said, "it turns out that armor plate patterns in the fish are controlled by the same gene that creates this clinical disease in humans. And this finding is related to the old argument whether Nature can use th...

Researchers trace evolution to relatively simple genetic changes

New Clues Add 40,000 Years to Age of Human Species

...searchers have uncovered evidence suggesting human bones found at that time are roughly 195,000 years old. The researchers believe the findings may bolster the “Out-of-Africa?hypothesis that suggests we all trace to an ancient line that first evolved in Africa and then displaced other hominids as recently...
