The age of the Earth: 4.600.000.000 years. It is difficult to imagine how much time is it. First, the primitive Earth and its extreme conditions, where the first prokaryotic cell appeared. Then, prokaryotic photosynthesis (cyanobacteria) originated oxygen accumulation in the atmosphere, so the e... Read More
The hand print image was featured in a short video by Emily Driscoll for NPR, swabbing the NY subway by artist Craig Ward. Note: the only thing I contributed was the image. I was not involved in the experiment. I would not advocate for doing this experiment outside of a lab for safety reasons... Read More
In this new video episode of Virus Watch, you'll see how the Zika virus particle is built, and how it binds to an antibody that blocks infection. All in gorgeous three dimensional views provided by recent structure studies. Read More
Lung ultrasound has been shown to be highly effective and safe for diagnosing pneumonia in children and a potential substitute for chest X-ray, according to a study conducted at the Icahn School of Medicine at Mount Sinai. Results are currently published in the medical journal Chest. Read More
Matrix-assisted laser desorption / ionization time-of-flight (MALDI-TOF)
The principle is the bacteria grown on a solid medium and transferred to a steel plate. The sample be shot with a laser and fragments are separated by size / charge. Fragment patterns are a fingerprint that can be used bot... Read More
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...

DURHAM, N.C. -- Researchers at Duke Health are fine-tuning a test that can determine whether a respiratory illness is caused by infection from a virus or bacteria so that antibiotics can be more precisely prescribed. Read More
Vaccines are like pathogen imposters - they mimic these 'bad guys' in order to provoke a response from our immune systems, remove the invader and begin the healing process.
One of the key components in a vaccine is an adjuvant, which serves to enhance our body's immune response to vaccination... Read More

Biologists are beginning to understand how the trillions of microbes in and on our bodies shape our health. But differences between any two people’s microbial populations are enormous. Most people share around 99 percent of their DNA with the person next to them, but they have a significantly sm... Read More

When I have to explain the organism classification to my students I usually use the one stablished by Woese in the 70s. In this classification, all living things are classified in six kingdoms, that are Eubacteria, Archeobacteria, Protista, Plantae, Fungi and Animalia. All of these groups evolve... Read More
I have long believed that there are many ways for students to learn. In several of my classes, I encourage students to use "creative" approaches to explore course concepts. In the Fall of 2015, here is what my micronauts in my Microbiology course at the University of Puget Sound came up with..... Read More
