Biology Plug N' Play

When you're hard drive fails, you order a new one online and then swap it out. Why can't we do that for biological parts as well? From DNA robots and "organs-on-a-chip" to nanobristles that grab-and-release drugs, this slideshow explores the two major goals of synthetic biology: to build new bio... Read More

Mumps virus protein

This confocal micrograph shows the mumps virus protein (turquoise) in the endoplasmic reticulum of a cultured cell. This is a region of the cell that processes proteins. This particular protein is possibly involved in determining how effectively the virus can infect people. By looking at how it ... Read More

Inducible clindamycin resistant (D-test positive) Staphylococcus aureus.

This isolate was also Methicillin resistant. It was my first D-test positive S. aureus isolate during my work on Inducible clindamycin resistance among staphylococci at Universal College of Medical Sciences and Teaching Hospital, Bhairahawa, Nepal. Read More

The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Image ... Read More

Model Organism gone wild

Some wild clones of social amoebas farm the bacteria they eat, but this is a losing strategy if nonfarming amoebas can steal the farmers’ crops. To make the strategy work, the farmers also carry bacteria that secrete chemicals that poison free riders. The work suggest farming is complex evolutio... Read More

Clues to Making Vaccine for Infant Respiratory Illness

Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have identified the structure of a critical RSV component called the fusion glycoprotein.

Respiratory syncytial virus, or RSV, is a respiratory virus that infects th... Read More

Neoscytalidium dimidiatum arthrospore

It is a well recognized uncommon cause of skin and nail infection of the hands and feet . Unlike Dermatophytosis these mould infections are not contagious. There are few reports of invasive infection caused by N. dimidiatum; most infections occurred in immunocompromised hosts. Arthrospores are ... Read More

Fighting Infection by Clonal Selection

In 1960, Australian immunologist Frank Burnet won a Nobel Prize for his contributions to immunology. Etsuko Uno and colleagues at the Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia, explain Burnet's clonal selection theory in an animation of the body's response to St...

Reducing antibiotic requests from patients with viral infections

For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More
