Researchers have reanimated an ancient, giant virus from 30,000-year-old Siberian permafrost that is almost not of this world--well, the world as we know it now, anyway. “Sixty percent of its gene content doesn’t resemble anything on earth,” reported one of the study's authors.

Listeria bacteria has been enlisted by researchers to selectively infect metastatic pancreatic cancer cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue. Mice livers are shown above. The saline control liver on the left presents a large number of metastases compared to the liver on the right which was subject to the radioactive Listeria treatment. ...

Have you heard about two new gigantic viruses that have been discovered? They measure around 1 micrometer long & half that across – larger than some eukaryotic cells! Massive genomes up to 2.5 Mb (millions of base pairs) are present to match their giant size. Their discovery raises many questions on viral diversity that remains unexplored.

The deadliest substance known to man is a recently discovered type of botulinum toxin (botox). The scientists who discovered it haven’t found an antitoxin yet, so they have decided not to publish the gene sequence due to security concerns. The toxin comes from the bacterium Clostridium botulinum and blocks the chemical signals that makes nerves work, causing botulism and death by paralysis. The image shown above is the protein structure of botulinum toxin.

This is a single drop of seawater, magnified 25 times. The amazing image shows bacteria, worms, fish eggs, crab larva, diatoms, and much more. Think about THAT next time you swallow a mouthful of seawater.

Deinococcus radiodurans is an extremophilic bacterium, one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and is therefore known as a polyextremophile and has been listed as the world's toughest bacterium in The Guinness Book Of World Records.

As a secondary school educator, I often see students sharing their drinks with one another. This bugs me more than anything because it causes germs to be easily spread from one person to another. The problem is, students have this misconception that if they are not sick, then the person they are sharing their drink with won't get sick either. Sounds rational, but is it true? Definitely not. Each person's immune system is unique, and so is our microbiome (as described in the video below). What may be harmless to one person may not be so much to another. I believe this video does an excellent job demonstrating that not only are humans unique in a sense that we each have our own personalities, have different occupations, and come from differe ...
