Understanding The Neuron's Green Architecture
Being green is a lifestyle. Turns out, each of your neurons is deeply committed to that green lifestyle - and you didn't even know it. In just a thousandth of a second, a neuron can dump up to 5,000 molecules of its chemical messenger - a neurotransmitter - into the synapse, where it will trigger an impulse in a neighboring nerve cell. The neuron is a recycler par excellence when it comes to these neurotransmitters. Neurons must not only ready neurotransmitter receptors to receive the signals coming fast and furious, but they must also recycle receptors that have been used. And you thought you had recycling problems? Exercise And Mental Stimulation Both Boost Mouse Memory Late In Life
Physical exercise is known to be good for the aging brain, but what about mental stimulation? Does enrichment that helps older people work well for the young and middle-aged, or do they need something else? A new article tells how, in an animal experiment, older adults appear to benefit from either or both mental and physical enrichment. For the young and middle-aged, exercise is key. 'Promiscuous' Area Of Brain Could Explain Role Of Antidepressants
A study at Baylor College of Medicine in Houston may lead to a better understanding of how antidepressants like Prozac work -- and how to make them more effective.According to results published in today's issue of the journal Neuron, a study in mice proposes that dopamine and serotonin neurotransmitter systems in the brain occasionally get their signals crossed, causing delays in stabilizing mood. History of California Minimum Wage
This chart shows increases in the minimum wage in California from 1916 when it was 16 cents per hour to the present 8 dollars per hour (as of January 1, 2008). Shows the increase amount and percentage increase from the previous amount for each wage. From the California Department of Industrial Relations. Identifying Patients At High Risk For Total Hip Replacement
A new study examined patients with hip pain to determine their disease progression and to find out how many underwent total hip replacement over the course of several years. New Catalysts May Create More, Cheaper Hydrogen
A new class of catalysts may help scientists and engineers overcome some of the hurdles that have inhibited the production of hydrogen for use in fuel cells. Most hydrogen produced industrially is created through steam reforming. In this process, a nickel-based catalyst is used to react natural gas with steam to produce pure hydrogen and carbon dioxide. Finding Holds Promise For Treating Eye Disease And Cancer And For Heal
Scientists at Schepens Eye Research Institute have discovered that a particular immune cell contributes to the growth of new lymph vessels, which aid in healing. The discovery of this new role for the macrophage, published in the September 2005 Journal of Clinical Investigation, may ultimately inspire innovative treatments for blinding eye disease, as well as for other diseases, such as cancer, that rely on the lymph vessels to spread abnormal cells throughout the body. Powerful Mineral Mapper Heads To Mars
With the launch of NASA's Mars Reconnaissance Orbiter spacecraft, the Compact Reconnaissance Imaging Spectrometer for Mars -- or CRISM -- joins the set of high-tech detectives seeking traces of water on the red planet. Built by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., CRISM is the first visible-infrared spectrometer to fly on a NASA Mars mission. Its primary job: look for the residue of minerals that form in the presence of water, the "fingerprints"left by evaporated hot springs, thermal vents, lakes or ponds on Mars when water could have existed on the surface. Google Ogles Plug-In Hybrids
Will the search engine leviathan end the hunt for a commercial hybrid? In Autopia. Gene Discovery Aids Understanding Of Common Inherited Neurological Dis
Scientists have identified the gene responsible for one type of Charcot-Marie-Tooth disorder, a common inherited neurological disease, thanks to the chance appearance of a strain of impaired "pale tremor"mice in a research laboratory. Researchers tracked down the gene responsible for similar disability in people. Charcot-Marie-Tooth disorder causes leg pain, muscle weakness and foot deformities.
