Scanning Electron Micrograph Of My Toothbrush!

Last month Johnny posted about an offer from ASPEX. They have desktop SEM (Scanning Electron Micrograph) and will scan a sample of anything you send to them.

The offer still stands. Follow the instructions here to get your dead bugs and rotten food scanned for free.

I sent in my toothbrush and they sent me an email with the results the other day! So here it is:

Pretty interesting, huh? They also put up two other toothbrush scans:

FREE Scanning Electron Micrographs of Just About Anything

An interesting offer from ASPEX
November 10, 2009 2:54 PM - by PZ Myers


I had my doubts about this; I got an offer from ASPEX corporation to let people get free scanning electron micrographs of just about anything. They make a desktop SEM (Scanning Electron Micrograph), and all you have to do is fill out a form and mail it in with your sample of a dead bug or a microchip or bacon, and presto, within a few weeks they'll have it scanned in and the image available on their website.

I asked them if they knew how many readers I have, and they said no problem, they can handle it.

Huh.

Well, you heard them. Scavenge your trash cans, dig into your local sources of vermin and oddments, and send them in. I'm thinking this could be really fun for any school teachers out there — you could have the whole class looking for interesting specimens to zoom in on. You can see their current galleries for ideas.

If you do send something in to get scanned be sure to note that you found them via PZ; and be sure to come back here and share your scan with the rest of us!

Interesting Study Regarding Cancer Treatment For Religious

schiavo protestNo one wants to get cancer. If someone gets it, how do they handle treatment? How do they face their own imminent death?

A recent study about End of Life Care (EOL) for people with terminal cancer produced some interesting results that I had to share with you.
Link Between Religious Coping And Aggressive Treatment In Terminally Ill Cancer Patients

"Recent research has shown that religion and spirituality are major sources of comfort and support for patients confronting advanced disease. We focused specifically on positive religious coping, on people who rely on their faith to handle the stresses of serious illness and approaching death. Our findings indicate that patients who turn to religion to cope in times of crisis, such as when facing death, are more likely to receive aggressive care when they die."

The study involved 345 advanced cancer patients at seven hospital and cancer centers around the country.

An analysis of the data showed that patients identified as positive religious copers had nearly three times the odds of receiving life-prolonging care, in the form of being on a ventilator or receiving cardiopulmonary resuscitation, in the final week of life. Even after researchers accounted for the influence of important factors such as age, ethnicity, or other coping techniques, the connection between religious coping and aggressive EOL care held up.

The researchers also found that religious copers in the study were less likely to have completed advance medical directives, such as a living will or do-not-resuscitate order, which can limit the extent of such interventions in advance. The effects of religious coping on the use of intensive medical care in the last week of life remained significant even after adjusting for differences in advance care planning.

Wow. So, if you're deeply religious, you go to great lengths, even if it reduces the quality of your remaining hours and days, just to stay alive. How bizarre. Shouldn't you be happy and eager to die and be on your way to heaven? Why cling to life in your hospital bed, tied up to tubes and machines, just to be not dead for another week?

Help Identify This Microscope!

I got my microscope! And I need your help. This thing is awesome (I think), but I have no idea what it is. It has no name on it. I have no idea even what the magnification is. I've dusted it carefully and now I'm waiting for UPS to deliver the slides and slide covers. I am still trying to figure out how to get a temporary light source to work, then I have to figure out a permanent lighting solution.

Oh... at the end of the technical bits, I need to rant a bit, in case you're interested.

Neece's Microscope

OK! The slides arrived. I've looked up Optical Microscopes and I know more than I did already. Don't think you're off the hook though. I still need you.
