Power in numbers – collective antibiotic resistance

For over 70 years, antibiotics have been a critical component of the arsenal used by healthcare providers to combat bacterial infections worldwide (1). Antibiotic use has become so prevalent that over 70 billion doses were consumed globally in 2010 (1). Due to the widespread use of antibiotics, some bacteria have developed antibiotic resistance and become… Read article →

Bacteria misbehaving in space

Tougher and more virulent? Human biology presents numerous limitations when it comes to space travel. Bacteria are more adaptable, robust and resilient, and are known to thrive in even the most extreme environments. But how do they fare in space? To date, numerous bacterial experiments have been conducted in Earth’s orbit. We know that bacteria… Read article →


Antibiotic resistance

Combating drug-resistant superbugs

Antibiotics have been used for the last 80 years to treat patients with bacterial infections. While antibiotics have greatly reduced illness and death resulting from these infections, their use has been so prevalent that microbes have adapted to them, eliminating their effectiveness. These microbes are named antibiotic-resistant superbugs. Superbugs can acquire resistance genes either by… Read article →

Metagenomics and microbial single cell genomics – a winning team

Deciphering the world around us – the “microbial dark matter” (1) – is a remaining challenge in environmental microbiology. Even after decades of 16S rRNA gene-based surveys, there are strong indications that the diversity of bacteria is still not exhaustively described even on high taxonomic (phylum) levels and that 16S rRNA sequences, representing novel bacterial… Read article →

Combating antibiotic-resistant bacteria

The CDC estimates that each year in the United States, antibiotic-resistant bacteria sicken two million people, and at least 23,000 people die as a direct result. In addition, antibiotic resistance is a threat to animals, agriculture, and the economy. In March of 2015, the White House released a comprehensive national action plan to combat antibiotic-resistant… Read article →
