Parents of healthy newborns often remark on the miracle of life. The joining of egg and sperm to create such delightful creatures can seem dazzlingly beautiful if the chromosome information from each parent has been translated properly into the embryo and newborn.

AP - The tribes of the lower Klamath River have since ancient times decorated themselves with condor feathers when they performed the dances designed to heal a world gone wrong.
A Dresden research team used laser tweezers to measure the friction between a single motor protein molecule and its track. The team found that also within our cells, motors work against the resistance of friction and are restrained in its operationâ€"usually by far not as much though as their macroscopic counterparts. These first experimental measurements of protein friction could help researchers to better understand key cellular processes such as cell division which is driven by such molecular machines.

AFP - The public's "right to starlight" is steadily being eroded by urban illumination that is the bane of astronomers everywhere, the International Astronomical Union said on Friday.
Our genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases. Scientists have known for a long time that when DNA is damaged, a key enzyme sets off a cellular 'alarm bell' to alert the cell to start the repair process, but until recently little was known about how the cell detects and responds to this alarm. In a study published today in Nature Structural and Molecular Biology, researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have identified a whole family of proteins capable of a direct response to the alarm signal.

A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.

University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. That ability to optically steer cells could be a major step in harnessing the healing power of stem cells and guiding them to areas of the body that need help.

Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter".

Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of nature's most elusive forces - the "weak interaction". Their work, which reveals the largest effect of the weak interaction ever observed in an atom, is reported in Physical Review Letters and highlighted in the August 10th issue of APS's on-line journal Physics (physics.aps.org).

A University of Cincinnati sociologist combed through newspaper accounts of 19th and 20th century Ohio executions to understand how executions became more "professional and scientific" in character. Annulla Linders, an associate professor of sociology, presented the paper Aug. 9 at the 104th annual meeting of the American Sociological Association in San Francisco.

A new class of molecules capable of blocking the formation of specific protein clumps that are believed to contribute to Alzheimer's disease pathology has been discovered by researchers at the University of Pennsylvania School of Medicine. By assaying close to 300,000 compounds, they have identified drug-like inhibitors of AD tau protein clumping, as reported in the journal Biochemistry.
