These Renderings of HIV Show That a Deadly Virus Can Be Beautiful

For those of us who are normal, non-scientist people, an image of a virus doesn't necessarily hold any meaning. Which floating orb is a healthy cell? And which one is the actual virus? The CGSociety recently invited artists to create renderings of the HIV virus in blood—and the winning images ar... Read More

1 in 25 patients gets infection in hospital

When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More

Guinea Worm Said to Infect Few in 2013

Only 148 cases of Guinea worm disease were found in the world in 2013, a 73 percent drop from the 542 cases found one year earlier, the Carter Center announced Thursday.

Along with polio, Guinea worm is one of two diseases hovering on the brink of extinction, with fewer than 1,000 cases annua... Read More

Pathogen turns protein into a virulence factor in one easy step

To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. In a study to be published May 7 in mBio, the online open-access journal... Read More

Virus-induced fever might change bacteria from commensal to pathogen

Neisseria meningitidis may cause septicemia (bacteria in the blood) and meningitis (infection of the membrane surrounding the brain), but the bacterium colonizes the nasopharynx in 10-20% of the human population without causing disease. Although understanding how the bacterium changes from a com... Read More

GM rice delivers antibodies against deadly rotavirus

Researchers have added an antibody to fight rotavirus into the rice genome. A strain of rice genetically engineered to protect against diarrhoeal disease could offer a cost-effective way to protect children in developing countries, according a study published in the Journal of Clinical Investiga...

Battling Infection With Microbes

The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, Caltech professor of biology and biological engineering Sa... Read More

Resurrecting ancient microbes to understand evolution

When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?

Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... Read More

How to give a great lecture

There are many elements that go into making a great lecture, but the most important one is to lose the notes. If you are giving lectures in a course at any level, the worst practice you can engage in is to rely on notes. This behavior is problematic for several reasons. You will not properly kno...

Bird flu researchers want to create deadly virus in lab

Researchers said Wednesday they want to create a lab version of a deadly emerging bird flu in order to study a strain that might be more infectious to people. Responding to past concerns about such research, the U.S. government said it will require extra safety measures.

The H7N9 bird flu vir... Read More

Some of My Best Friends Are Germs

I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a labo... 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

To combat the overuse of antibacterials, stop using the absolutely terrible word, "antibiotic"

There are many reasons why bacteria evolve resistance to antibacterials, but one of the preventable reasons is the over-prescription of antibacterials to patients who don't have bacterial infections. But how to get people to stop asking for antibacterials? My suggestion is to stop using the wor... Read More

Research project studies fungi found in popular drink
