Seeing how evolutionary mechanisms yield biological diversity
A international team of scientists has discovered how changes in both gene expression and gene sequence led to the diversity of visual systems in African cichlid fish. No Need For Reduced Alcohol Consumption In Later Life, Study Suggests
Provided they stick to the same guidelines about alcohol consumption as younger adults, regular moderate drinking poses no additional risks to the 'over 65s,'and may even bring health benefits, according to two new studies. Researchers Create New Super-thin Laser Mirror
Engineers at UC Berkeley have created a new high-performance mirror that packs the same 99.9 percent reflective punch as current high-grade mirrors, but in a package that is 20 times thinner and easier to manufacture. The new mirror could dramatically improve the design and efficiency of next generation laser optics for such devices as high-definition DVD players, computer circuits and laser printers. [Cool] Florida's Three Major Schools All Lose For the First Time Since
For the first time since 1978, the Gators, 'Noles and 'Canes lost on the same day. Biomedical Engineers Advance On 'Smart Bladder Pacemaker'
Duke University biomedical engineering researchers have moved a step closer to a "smart bladder pacemaker"that might one day restore bladder control in patients with spinal cord injury or neurological disease. The team's findings show that a device that taps into the urinary "circuit"in the spinal cord could selectively coordinate the contraction and release of muscles required for maintaining continence. New Infrared Tool Measures Silicon Wafer Thickness
A new instrument under development at the National Institute of Standards and Technology (NIST) uses infrared laser light to precisely measure the thickness of 300 millimeter silicon wafers. NIST researchers hope the tool, with further refinements, will allow them to establish a new calibration service for "master wafers"used in semiconductor the industry to measure wafer thickness. Correct your chemical spelling mistakes
Chemist Adam Azman contacted me more than two years ago to ask if I knew of a free or open source chemistry spellchecker custom dictionary for Word or OpenOffice. Searches had revealed only paid-for dictionaries. We both agreed that a free chemical spellchecker would be very useful to all scientists working with chemicals, so Adam [...]Correct your chemical spelling mistakes is a post from: Sciencebase Science Blog Boosting Blood Vessels With Brain Derived Neurotrophic Factor
In the March 1 issue of the Journal of Clinical Investigation, Shahin Rafii and Barbara Hempstead along with colleagues from Cornell University, delve into the mechanisms underlying the angiogenic effects of brain derived neurotrophic factor (BDNF) in adult blood vessels. Life and Death in the White House: Assassinations and Mourning
This presentation looks at assassination of U.S. presidents and the role of the U.S. Secret Service in protecting presidents. Discusses assassinations and assassination attempts, including Abraham Lincoln, John F. Kennedy, Andrew Jackson, and James A. Garfield. Includes a chart listing all of the assassination attempts and outcomes. Part of a larger exhibit on the U.S. presidency by the Smithsonian Institution's National Museum of American History.
