A team of undergraduate students at the University of Wisconsin are attempting to shine light on the problem of electricity-gobbling bulbs by creating a light source that doesn’t require an electric input at all. Genetically engineered E. coli housed within a bulb-like casing can produce biolumi... Read More
Most of the life on Earth comes in the form of small, single-celled organisms. But even though we knew there was incredible diversity at the microbial level, these cells all look pretty similar under a microscope. For many of the bacterial species we've identified, the key step has been growing ... Read More
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
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...

In Pakistan IDUs is the highest HIV infected risk group, mainly because of frequent sharing of contaminated needles, paid blood donations and unprotected commercial sex. These IDUs are serving as bridge to transfer the HIV to general population transmitting the virus to their wives and children.... Read More
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
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
Through the serendipity of science, researchers at the University of Pittsburgh have discovered a potential treatment for deadly, drug-resistant bacterial infections that uses the same approach that HIV uses to infect cells.
The National Institutes of Health-supported discovery will be descr... Read More
There has been a lot of news lately about the bacteria living in our gut—the human gut microbiome. Researchers are learning which bacteria live there, who is naughty and who is nice and even a somewhat distasteful way to replace naughty with nice (a fecal transplant).
What gets lost in all of... Read More
Using new advances in synthetic biology and our updated understanding of Martian geochemical conditions, we should be able to inoculate the planet Mars with specially designed extremophilic microbes in an attempt to start (or re-start) life on its surface. This could be the largest and most auda... Read More
UCLA researchers now have the first evidence that bacteria ingested in food can affect brain function in humans. In an early proof-of-concept study of healthy women, they found that women who regularly consumed beneficial bacteria known as probiotics through yogurt showed altered brain function,... Read More
A genetically modified version of herpes simplex virus type 1, the same virus that causes cold sores, shrank tumors of the deadly skin cancer melanoma in a clinical trial, according to Amgen, which is developing the experimental cancer treatment.
Patients in the trial were in the late stages ... Read More
Science Magazine has recently published a study carried out by Dr. Robert Brucker and Dr. Seth R. Bordenstein from Vanderbilt University in Nashville (USA) that seems to provide clues reinforcing the “hologenome theory of evolution”. This research suggests that the gut microbiome may have a fund... Read More
The first cell may have originated in a salty soup in which large biomolecules cluster spontaneously to form a protocell, chemists at Radboud University Nijmegen discovered. PNAS published their work on July 1.
How did the first cell originate in evolution? It is a chicken or the egg causalit... Read More
When you peer through the smear on the screen of your smartphone, thousands of tiny microbes are staring back at you, waiting to hitch a ride on your fingertips.
Harmful microbes lurk everywhere — doorknobs and faucets, locker rooms and hospitals. It's enough to make a germophobe afraid to to... Read More
For the second time in a matter of weeks, a group of researchers reported a link between the food people eat and bacteria in the intestines that can increase the risk of heart attacks.
Two weeks ago, the investigators reported that carnitine, a compound found in red meat, can increase heart d... Read More
How much a person eats may be only one of many factors that determines weight gain. A recent Cedars-Sinai study suggests that a breath test profile of microorganisms inhabiting the gut may be able to tell doctors how susceptible a person is to developing obesity.
The study, published online T... Read More
In this blog, I share some "first word that comes to mind" responses of my freshman biology class to the words "germ," "bacteria," "cell," and "DNA." The way that we perceive an idea or concept definitely impacts our relationship with it. Thus, finding out what students think, coming into our ... Read More
