Freaks of Nature and Bridgeless Gaps

Readers from waaaay back may recall an event I helped out with a few years ago, bringing together scientists, philosophers, and our resident IDist to discuss evolution and intelligent design. One of the speakers was University of Iowa professor Mark Blumberg, a colleague in the Department of Psychology. Dr. Blumberg also happens to be a…

New Ebola subtype confirmed

Few things can take me out of blogging hibernation (especially when the next grant deadline is Monday…) However, one of those things that I’ll carve out time to write about is an interesting, hot-off-the-presses Ebola paper, and especially one describing a new strain of the virus–and there just happens to be such a paper in…

An interesting new paper is just out today in PLoS ONE. You recall the announcement a few years back that soft tissue that resembled organic tissue had been isolated from a Tyrannosaurus femur. This started off a huge controversy in the field (and beyond)–researchers disagreeing with each other whether the structures seen were indeed blood…

By Matthew Fitzgerald How can infection be a carcinogen? How do infectious diseases lead to cancer, if at all, is still a highly debated area of…

This is the second of 6 guest posts on infection and chronic disease. By Rachel Kirby In light of April being Autism Awareness Month it is only natural that certain topics be brought about in the media. Until now I was not aware of the controversy behind the “risk factors” of autism. Let’s begin with…

This is the first of 6 guest posts on infectious causes of chronic disease. By David Massaquoi Is this the Beginning of the end of antibiotic resistant problem or just another scientific false hope of eradicating microorganisms that have co-existed with humans for millions of years? In the days before antibiotics, some researchers saw bacteriophages,…

Early this week, grant application; yesterday and today, IRB and IACUC for another project. But once again, fellow Sbers are keeping me busy reading about stories I’d like to be writing on; see yet again Mike on E. coli O157:H7–everything old is new again; Ed on a new study showing yet again how amazing bacteria…
