Why Do We Get Old, and Can Aging Be Reversed?
Everybody gets older, but not everyone ages in the same way. In this episode, Steven Strogatz speaks with Judith Campisi and Dena Dubal, two biomedical researchers who study the aging process.
Nobel Chemistry Prize Awarded for CRISPR ‘Genetic Scissors’
Emmanuelle Charpentier and Jennifer Doudna have been awarded the 2020 Nobel Prize in Chemistry for their development of CRISPR/Cas9 genetic editing.
Biodiversity Alters Strategies of Bacterial Evolution
In evolution, context is everything: Bacteria with neighbors evolve to rebuff viruses in a different way.
Doudna’s Confidence in CRISPR’s Research Potential Burns Bright
Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.
Gene Drives Work in Mice (if They’re Female)
Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.
In the Nucleus, Genes’ Activity Might Depend on Their Location
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
CRISPR Gene-Editing Pioneers Win Kavli Prize for Nanoscience
The inventors of a “Swiss army knife” for genome editing received prestigious honors, as did pioneering scientists in astrophysics and neuroscience.
New Model Warns About CRISPR Gene Drives in the Wild
Two new papers urge caution in using powerful genome-editing technology against invasive species: Models show that aggressive gene drives can’t be contained in the wild.
Genetic Engineering to Clash With Evolution
Gene drives promise to spread a trait across an entire population. But evolutionary forces are going to alter even the best-engineered plans.
