Microbe/Mineral Affinities

This is a paper from the Geomicrobiology lab at the Jackson School of Geosciences at the University of Texas at Austin. It was recently published in a special issue of Geomicrobiology Journal focused on geomicrobiology of subsurface microorganisms in cave environments.

In this study we attemp... Read More

Hepatitis B viruses in bats

Hepatitis B virus (HBV, illustrated) is a substantial human pathogen. WHO estimates that there are now 240,000,000 individuals chronically infected with HBV worldwide, of which 25% will die from chronic liver disease or hepatocellular carcinoma. The hepatitis B virus vaccine is highly effective ... Read More

Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... Read More

On a Cellular Level, We Are ALL Overachievers!

In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More

Discovery of the Sixth DNA base?

Scientist has described the possible existence of sixth DNA base, the methyl-adenine (mA) this week.

Deoxyribonucleic acid (DNA) is a polymer of nucleotides, which encodes every genetic information of living existence. The entire genetic information are stored within DNA as the form of millio... Read More

Receptor for new coronavirus-EMC identified

Viruses are obligate intracellular parasites, which means that they must enter a cell to reproduce. As virions are too large to diffuse passively across the plasma membrane, cellular pathways for uptake of extracellular materials provide entry routes. The first step in entry is adherence of viru...

Blastocystis Parasite Blog

Our bodies are made up by cells containing our own DNA. Plus 10 times as many with foreign DNA. The bacteria found on our skin, and inside our organs (intestine, vagina, mouth, nose, etc.) are referred to as our “microbiome”, outnumber our own cells by 10 to 1, and make up a vital organ with ind...

Fighting viruses - amazing new 21st century lab

Looking out of the window isn’t something most office workers would consider a luxury. But then, most people don’t work in a maximum security, biosafety level 4 high-containment research facility, working to protect the UK’s multi-billion pound agricultural industry from dangerous and highly inf...

Viral fiber art

Viruses inspire many different types of art, but I was unaware of the number of people who make viruses out of fiber! Keep reading for some photographs of what I have found. Read More

Why do viruses cause disease?

Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are ... Read More

Pandoravirus, bigger and unlike anything seen before

The discovery of the giant Mimivirus and Megavirus amazed virologists (and also many others). Their virions (750 nanometers) and DNA genomes (1,259,000 base pairs) were the biggest ever discovered, shattering the notions that viruses could not be seen with a light microscope, and that viral geno...

A saga of HeLa cells

We have been using HeLa cells in my laboratory since 1982, when I arrived at Columbia University Medical Center fresh from postdoctoral work with David Baltimore at MIT. I brought with me a line of HeLa cells and used them for 30 years for our research on viruses. Here is a story of how we lost ... Read More

The incubation period of a viral infection

The time before the symptoms of a viral infection appear is called the incubation period. During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g....
