Earlier this month the European Molecular Biology Laboratory (EMBL) published the DNA sequence of the genome of HeLa cells, the cell line that is widely used for research in virology, cell biology, and many other areas. This cell line was produced from a tumor taken from Henrietta Lacks in 1951.... Read More

Recently thousands of dead and decaying pigs were pulled from rivers in Shanghai and Jiaxing, China. Apparently farmers dumped the animals into the water after the pigs became ill, and porcine circovirus was subsequently detected in the in pig carcasses and in the water. Porcine circoviruses are...

Hi Drs. Despommier and Racaniello,
This week you wondered why the immune-activating receptor for Toxoplasma gondii, TLR11, is present in mice but not in humans. You noted that it looks like there's no selective pressure keeping it around in us an... Read More
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...

Diseases transmitted by mosquitoes have a devastating impact on global health and the situation is complicated due to difficulties with both existing control measures and the impact of climate change. Genetically modified mosquitoes that are refractory to disease transmission are seen as having ... Read More
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...

This episode: Some bacteria respond to attacks from other bacteria with their own deadly strike!
A simple new method better assesses the risks posed by emerging zoonotic viruses (those transmissible from animals to humans), according to a study published in PLOS Medicine this week. Dr. Simon Cauchemez and colleagues from Imperial College London in the UK and the Centers for Disease Control ... Read More
For what may be the first time, researchers have discovered a virus inside a host with a non-standard nuclear genetic code — one that differs from the standard genetic code that almost all living things use to produce proteins.
“The finding is significant because it shows that these viruses... Read More
Constructed in 2009 in the highly populated South End neighborhood of Boston, Massachusetts, the National Emerging Infectious Diseases Laboratories (NEIDL) facility contains labs that operate at biosafety levels 2, 3 and 4. Due to its location the NEIDL has faced a raft of legal and regulator... Read More
Researchers report the detection of a strain of Seoul hantavirus (SEOV) in pet rats in England and Wales. The discovery followed an investigation of a case of haemorrhagic fever with renal syndrome in Wales. Hantavirus RNA was detected via real-time reverse transcription-polymerase chain reactio...
