Researchers Link Early Stem Cell Mutation To Autism

In a breakthrough scientific study, scientists have shown that neural stem cell development may be linked to Autism. The study demonstrated that mice lacking the myocyte enhancer factor 2C protein in neural stem cells had smaller brains, fewer nerve cells and showed behaviors similar to those seen in humans with a form of autism known as Rett syndrome.

Mammalian Clock Protein Responds Directly To Light

We know that light effects the growth and development of plants, but what about humans and animals? New research explores this question by examining cryptochromes in flies, mice, and humans. In plants, cryptochromes are related to functions such as growth and development. Cryptochromes are present in humans and animals as well and regulate the mechanisms of the circadian clock. But how they work in humans and animals remains a mystery.

New Electrostatic-based DNA Microarray Technique Could Revolutionize Medical Diagnostics

Researchers have invented a technique in which DNA assays -- the key to personalized medicine -- can be read and evaluated with no need of elaborate chemical labeling or sophisticated instrumentation. Based on electrostatic repulsion that yields images visible to the naked eye, the technique could revolutionize the use of DNA microarrays for both research and diagnostics.

Physicists Create Millimeter-sized 'Bohr Atom'

Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, physicists have created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. The scientists used lasers and electric fields to coax potassium atoms into a precise configuration with one point-like, "localized" electron orbiting far from the nucleus.

Scientists say ailing penguins signal sea problems (AP)

Shown in this June 30, 2000 file photo, an oil-stained penguin is seen in the water on Dassen Island, near Cape Town, South Africa. In a paper published in the July edition of the journal Bioscience conservation biologist P. Dee Boersma says that dwindling march of the penguins is signaling that the world's oceans are in trouble. (AP Photo /Obed Zilwa, File)AP - The dwindling march of the penguins is signaling that the world's oceans are in trouble, scientists now say. Penguins may be the tuxedo-clad version of a canary in the coal mine, with generally ailing populations from a combination of global warming, ocean oil pollution, depleted fisheries, and tourism and development, according to a new scientific review paper.
