Symbiotic microbes’ origin discovered after man impales hand on branch
Two years ago, a 71-year-old Indiana man impaled his hand on a branch after cutting down a dead crab apple tree, causing an infection that led University of Utah scientists to discover a new bacterium and solve a mystery a... Read More
When I began listening to TWIV almost a year ago, I had just switched majors from philosophy to biology. I am now writing to you good people at TWIM at the end of my first undergraduate summer research gig, where I have had qui... Read More
The last few decades have seen dengue, a mosquito-borne viral infection, becoming one of the major public health concerns in the tropical and sub-tropical countries. So much so that over 40 per cent of the world’s population (2.5 billion) is at risk from dengue. According to the World Health Org... Read More

According to a new report in the journal Antiviral Therapy, researchers from the Washington University in St. Louis have found that nanoparticles loaded with bee venom are capable of destroying the human immunodeficiency virus (HIV) while leaving the body’s cells unharmed. In a radical departure... Read More
A prototype medical dressing that 'lights up' when dangerous bacteria are present has been developed at the University of Bath. The invention means that life-threatening infections in child burn victims could in future be detected with nothing more than a UV light.
The dressing contains nanoc... Read More
Scientists at Karolinska Institutet in Sweden have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to t... Read More
Research with human tissue and cells suggests that genetic variations, in addition to failure to comply with treatment regimens, may account for some failures of an anti-HIV drug to treat and prevent HIV infection. Read More
