Time lapse microscopy I have captured of human neutrophil, phagocytosing several bacteria at once. 800x magnification
Once the bacteria are taken in they are killed with oxidants as visualized with a fluorescent marker. Images captured with a laser scanning microscope (Zeiss). Magnification (800X)

It was the Fall of 2009 and the economy left many of us unemployed for the first time ever! I'm SO glad I LOST MY FULL TIME JOB. Just like that, the corporate world is cruel, they pulled the rug right out from under me! I only got 1 week of notice too!!! It doesn't matter how great your severance package is, it is no fun to have your life turned upside down without giving you time to process... read more
If you are in the preliminary stage working toward applying for a nursing program, I would love to meet you! I know it is hard work taking the courses you are studying and completing all requirements needed to make your application. Since 2010 I've studied biology, chemistry, microbiology, anatomy and physiology, in depth. These are not the easiest subjects to learn, especially if you are returning... read more
So I'm sure we all want to EXCEL in school! Who doesn't??? Well how can you do that? Here are a few tips! 1.) TAKE GOOD NOTES IN CLASS. When in class, be very engaged in the topic being discussed. That may require taking extra notes, side points your teacher/professor make. It most definitely includes asking questions! No question is dumb question. Don't move on unless you are clear... read more
Why is it important to know these stages???
I thoroughly enjoy tutoring subjects that appear in bold print on my profile. As time permits, I will be adding the subjects which are not bolded. As a student or parent seeking a qualified or certified tutor, look for the bold subjects listed on tutor profiles. The non-bolded subjects are those which the tutor is interested in completing the certification exams. During my winter break from... read more
The moans and groans are audible! "Why do I have to do homework??" Let me tell you why I assign additional work outside of a tutoring session ... It is my job to be sure that you are able to apply and integrate the materials we cover in addition to being able to absorb facts and information. Sometimes what I call 'homework' is nothing more than finding an article about the topic we are... read more
When I tutor people especially in the more challenging science courses like Microbiology and Anatomy and Physiology I see students just memorizing and not understanding to overall picture. Especially in Microbiology where you have to learn the make up of different viruses and bacterial cells then use that information to see how that antibiotic works. What I found to work best is to ask why... read more
The philosophy of teaching I have embraced in thirty years of teaching medical students and college students is based on the belief that learning is student centered and that students need to be equal partners in the learning process. There must be present, a student mentor relationship of trust. There should, however, always be an authoritative presence in the mentor. This leadership should... read more
Whatever subject you are studying, a good approach is to come home at the end of the day and review your notes. Anything you don't understand, formulate into a written question so you can check on it yourself or ask your teacher or tutor for help understanding. Waiting till the night before an exam will likely make you nervous. It will be hard to have enough time to prepare. Study a little... read more
The ELAs are coming. Is your child ready? Well, if your child was not practicing reading, vocabulary and math for a few hours per week, there is a great chance that you need a tutor to explain the subject curriculum one more time. As the time goes by, the memory fades away. My students play games that help to train their memory, speed and attention. Education is a year long (including... read more
FUN Science Facts: feel free to add a comment or share something interesting you know about SCIENCE!
Did you know... 10 percent of all human beings ever born are alive at this very moment!
I think www.wyzant.com is doing a great job bringing together students and tutors. Even though some tutors charge up to $70/hour and higher, it is hard to see my qualifications until you try. Therefore, I charge $25/hour so that the potential students would try me out and see how good I am on the background of professors and teachers. I am trying to bring affordable tutorials to my students... read more
(1) To help understand and remember taxonomy (how organisms are organized), create Excel spreadsheets with the different taxonomic groups and characteristics that distinguish them from one another. (2) For dichotomous keys, first ask a question that separates bacteria out into two large groups, then ask questions that separate bacteria into smaller and smaller groups. (3) Know the differences... read more

There are so many terms and concepts to remember in biology. Concept maps help to show the relationships between concepts and organize information. Labeled boxes or circles with arrows arranged in a branching design make up concept maps. Drawing one of your own or with help can be an effective study tool. Alicia
