Unearthing the Evolutionary Origins of Insect Wings
Jef Akst | Apr 4, 2022 | 6 min read
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.
Targeting Antibiotic-Resistant Bacteria with CRISPR and Phages
Anna Azvolinsky | May 18, 2015 | 3 min read
Researchers develop a CRISPR-based, two-phage system that sensitizes resistant bacteria to antibiotics and selectively kills any remaining drug-resistant bugs.

Contributors Michele Pagano wasn't even out of high school when he began his research career, growing bacteria or observing paramecia before the first bell rang. In an effort to appease his father, Pagano then headed to medical school and earned his MD in 1989, but he couldn't kick the research bug he caught back in that high school laboratory. So he received an additional specialty degree (a sort of Italian equivalen
Checking the Alignment
Jane Salodof Macneil | Sep 21, 2003 | 9 min read
Courtesy of European Bioinformatics Institute  KNOWLEDGE GAPS? Sequence alignments offer clues to both the function and evolution of novel genes. But a bewildering array of algorithms and parameters leaves many researchers unable to use these programs to their fullest potential. In the beginning, there was Needleman-Wunsch, which begat Smith-Waterman, which begat FASTA, which begat BLAST, and so on. Peel away the information technology jargon surrounding these alignment algorithms, and a

Courtesy of Roland BroschThe regions absent from the attenuated vaccine strain Mycobacterium bovis BCG Pasteur relative to the M. tuberculosis H37Rv genome are shown as gray boxes. Open reading frames (ORFs) are represented as pointed boxes showing the direction of transcription, with colors reflecting the functional classification of the ORFs similar to the ones on the TubercuList server http://genolist.pasteur.fr/TubercuList/.Not long after the genome sequence of Mycobacterium tuberculosis was
