Antibiotic use promotes Clostridium difficile growth

Antibiotics have been effectively utilized for decades in the treatment against infectious agents. However, antibiotic use has been known to have detrimental effects, including the development of antibiotic resistant bacteria and alterations to the microbiota. The microbiota is a community of bacteria that colonize the body and can influence metabolism, physiology, nutrition, and immune function.

3D Enzyme Imaging Could Help Scientists Create New Antibiotics

3D Enzyme Imaging Could Help Scientists Create New Antibiotics  Antibiotics are drugs that fight bacterial infections, either by killing the bacteria or impeding their reproduction. First discovered in the early 20th century, antibiotics transformed medicine and have saved countless lives. However, an increasing number of bacteria have developed antibiotic resistance and no longer respond to

Intro to Adeno & Lentiviruses

  In nature, adenoviruses and lentiviruses can be dangerous – HIV is a lentivirus, and adenoviruses can cause ailments such as the common cold, bronchitis and pneumonia. But in research, the two viruses are extremely useful, serving as powerful gene delivery tools that can introduce genes of interest into target cells. Here you’ll find an

The latest advances in DNA sequencing

While most geneticists pontificate on the ethical and technical implications of the latest gene-editing technology, others are busy perfecting preexisting techniques. Recently, DNA sequencing, a decades-old methodology, underwent democratization. A handful of enterprising companies revolutionized the technique, producing DNA-sequencing technology that cuts costs and production times. Out with the old order An industry-standard DNA-synthesis machine

The science behind gene editing

Over the past year, researchers have made startling advances in the area of gene-editing, reported the MIT Technology Review. Using a new genetic engineering methodology called Clustered Regularly Interspaced Short Palindromic Repeats, or CRISPR, scientists have modified human embryos, increased muscle mass in dogs and produced horn-less dairy cows. However, these achievements haven’t come without controversy.
