India starts countdown for Mars missionDavid Szondy
India has started the clock on its most ambitious space project to date. On Sunday at 6:08 IST, the Indian Space Research Organisation (ISRO) began the countdown for its Mars Orbiter Mission (MOM). If all goes to schedule, the unmanned probe will lift off on Tuesday from the First Launch Pad at the Satish Dhawan Space Centre (SHAR), on the island of Sriharikota at 2:38 pm IST atop a Polar Satellite Launch Vehicle (PSLV-C25), marking the point where India hopes to launch itself into the space-faring big leagues.
Da KJMagnetics, eis mais umas dicas sobre Magnetismo, aqui, a Lição é sobre a Direcção das Linhas de Força num Campo Magnético, e como os Ímanes de Neodímio são magnetizados:
All About Magnetization DirectionWhat do we mean by a magnet’s Magnetization Direction? Why do we care about this? Can a magnet’s magnetization direction be changed? What’s the difference between axially and diametrically magnetized magnets? How can I tell them apart? Why can’t I get a block magnet magnetized along the length or width? What magnetization direction should be used with directional sensors?
What do we mean by a magnet’s Magnetization Direction? Is it important?The strong magnets found at K&J Magnetics are called sintered neodymium magnets,. They are the most powerful type of permanent magnet available. Sintered means the metal is pressed together at high temperatures in a very specific way to make a strong magnet. You can learn a bit more about this process in How Neodymium Magnets are Made.
Ora, a Diversão é algo de importante, ainda mais para os Engenhocas, hé, hé...

Discovery shines a light on potential cure for Alzheimer's and Parkinson'sDarren QuickIt is generally believed that aggregations of proteins are responsible for brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. However, the difficulty has been in detecting the aggregates responsible and removing them from the brain. Researchers at Chalmers University of Technology in Sweden and Polish Wroclaw University of Technology have found a potential solution using lasers.
Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease are thought to be caused by aggregates of amyloid beta protein that start to inhibit proper cellular processes in the brain. Although it is technically possible to cure the diseases by detecting and removing the amyloid protein aggregates using chemicals, these chemicals are highly toxic and harmful to the patient.
