Some fungi are into dead bodies and waste piles

by Rosin Cerate in Rosin Cerate

For the past couple of years now, a fungus called Xylaria polymorpha has been munching on the buried roots of a beheaded tree on my parents' front lawn. In the grass surrounding the stump, X. polymorpha sends up a thicket of charcoal club-like mushrooms every summer. They look kinda like a dead man's fingers, which not coincidentally happens to be a common name for the fungus.... Read more »

Extracting goo from corpses to better understand them

by Rosin Cerate in Rosin Cerate

It's goo week here at Rosin Cerate. So far we've looked at forms of natural springtime goo. For today's post, it's on to a much darker and less life-affirming goo. We're going to take a peek at the viscous fluids you can extract from a corpse to determine where/when/how it became a corpse and other useful forensic information.... Read more »

Identifying a shooter by their snot

by Rosin Cerate in Rosin Cerate

I'm Canadian and didn't grow up on a farm or anywhere particularly rural, so it shouldn't be surprising to learn I've never fired a gun. Furthermore, guns are very far down on the list of things I'm interested in learning more about. Yet sometimes tooling around the scientific literature leads to unexpected topics, such as the forensic analysis of gunshot residue. Turns out there's a neat bit of biology involved, and thus we've got ourselves a quick blog post.... Read more »

5 things CSI gets right

by Stuart Farrimond in Guru: Science Blog

For Brits, this week sees the return of everybody’s favourite team of armed Police/crime scene/forensic scientist hybrids: the night shift of the Las Vegas Crime Scene Investigation dpt. (UK Channel 5, Tuesdays 9PM). Now entering its 12th season – it’s even been around since ‘seasons’ were called ‘series’ – CSI is the most watched TV [...]... Read more »

Forensics to the Rescue: Prosecuting Endangered Snake Poachers

by Arielle D. Ross in Salamander Hours

This week, I was lucky enough to handle a few live Ontario snakes during my herpetology course. This was quite a treat for me because, for as long as I can remember, I have held a fierce fascination for all … Continue reading →... Read more »

New Year’s Special: How Soon is Too Soon for an Alcohol Breath Test?

by Arielle D. Ross in Salamander Hours

As I mentioned in the latest “Top 3 Science links” post, for most of North America, New Year’s Eve signifies two things: a fresh start and/or alcohol. Sadly, the latter means that some of us will make bad decisions tonight, … Continue reading →... Read more »

Fingerprint evidence: not exactly what CSI showed you

by EE Giorgi in CHIMERAS

Every scientific type of analysis has an error rate. I've mentioned it before: science is not about certainty, it's about accurately measuring the uncertainties. Unfortunately, when it comes to forensic sciences, this causes a logical problem: scientists like to talk about being 90% sure about something, but in trials there's only two outcomes: innocent or guilty. You can't do 90% guilty and 10% innocent.It occurred to me that this was an issue when I heard somebody talk about how fingerprint an........ Read more »

What's eating you? - Bugs, bacteria, and zombies

by Laelaps in Laelaps



The trailer for Shaun of the Dead.


Not all zombies are created equal. The most popular zombie archetype is a shambling, brain-eating member of the recently deceased, but, in recent films from 28 Days Later to Zombieland, the definition of what a zombie is or isn't has become more complicated. Does a zombie have to be a cannibal corpse, or can a zombie be someone infected with a virus which turns them into a blood-crazed, fast-running monster?

For my own part, I have always preferred the cla........ Read more »
