Robots that "think for themselves" Fly's eyes: Can the nerves, eyes, and "brain" function of a fly be modeled within a computer circuit? Courtesy NeilsPhotography Engineers are trying to design machines that can "think for themselves" when on surveillance or search and rescue missions. Somehow the machines has to look at its environment and decide what to do. Have you ever tried to catch a fly? They are pretty good at seeing your hand and knowing just how to escape your grasp. If we can figure out how a fly can do it ... Can we figure out how a fly is able see, and find food, and escape from our fly swatters? With today's super microscopes, I am sure that we can visualize and model every nerve connection, muscle fiber, and eye facet. Computational biology David O’Carroll, a computational neuroscientist who studies insect vision at Australia’s University of Adelaide has been studying the optical flight circuits of flies, ...

Declared by the "The No Child Left Behind Program" (NCLBP) and the State of Minnesota, science is an important subject and required for student's after the graduating class of 2011 to pass in order to graduate. The first MCA Science test was handed out last year to students in 6th and 8th grade, since it was their first year testing students on Science the scores has not yet been posted. In the past, there were different types of MCA's passed out to student's, there was the MCA 1 and the MCA 2 and there is a plan for an MCA 3 in the year of 2014. With each different tests, it gets more and more rigorous, but the question is why? For each tests the standards have changed ( if you want to check out the standard for science in the MCA check out this link http://education.state.mn.us/MDE/Academic_Excellence/Academic_Standards/... and download Academic Standards: Science K-12 (2009)) in the past few years and the standards are changing to be a set higher than the years ...

Is the changing of the weather a sign of 2012?

Have you notice that this year is a bit different than these past few years? There is climate changes and I have found out that there is many places that have unusual weather going on. To find out what kind of weather is happening at other people's location I posted up a question on answers.yahoo.com (http://answers.yahoo.com/question/index;_ylt=Ai6ehEHIOirNwIoaUPUQaEAazKI...) to see if the weather is really a sign or a warning of 2012. Downtown St. Paul: Downtown St. Paul Courtesy Della Xiong For an example. In Minnesota, on Spring there wasn't as much rain as it usually did every year. September was the month that has the most rain. It seems as if September was Spring instead of Fall. And going towards October their were a couple days that have snowed, it was unexpected. It's like the weather shifted a month forward. So for me the cause of 2012 could be the weather, but I wasn't sure about it so I ask another question "Is the changing of the weather a sign of ...

Hair: the chemicals we put in it

Hair and the chemicals we put in it. Do you know what you are putting in your hair when you dye, perm, or relax your hair? Hair dyes contain harsh chemicals. Para Phenylenediamine is a potent allergen. It is also a possible carcinogen which is cancer causing. Reports suggest over exposure to hair dyes might increase the chances of forms of cancer such as lymphoma, multiple myeloma, breast cancer, and leukemia. Another chemical in hair dyes is lead acetate and lead is said to disrupt the function of your brain. Hair relaxers are mostly used by African Americans to get straight silky hair. I used to get these relaxers and thought they were great but now my hair has lots of breakage. So I no longer get them. Relaxers contain a chemical called lye also known as sodium hydroxide which are used in drain cleaners. This is a very strong potent chemical The relaxer breaks the protein bonds in the hair. If relaxers are misused the scalp can be severly burned and hair can fall out leaving ...

What are the side affects of the h1N1 and the flu vaccines?

plee057 9 hours ago

The "flu shot" vaccine side effects are usually the normal common reactions, and usually minor. some reactions are: about one in three people get a sore arm, little redness, or low fever from the shot, and an average of 10-15% of people feel tired or get a headache. The flu itself can cause serious problems, including GBS (Guillain-Barré Syndrome); the body's immune system attacks part of the peripheral nervous system. A large proportion of the world population will get H1N1 and the vaccine side effect risk is far smaller than the sickness. When vaccines are approved, which includes the H1N1 vaccine, they are guaranteed to be much less risky than the sickness they prevent. "There could be unknown side effects. Something could happen, but it hasn't, but we think that is highly unlikely," infectious disease and vaccine expert Mark Mulligan, MD, executive director of the Hope Clinic of the Emory Vaccine Center in Atlanta. An interview with the health ...
