Underwater telecom cables make superb seismic network

Posted · Add Comment

Photonic systems can transform underwater fiber-optic cables into a dense network of seismic stations to illuminate ocean-floor earthquake zones impossible to study today, according to a new study. The scientists turned 20 kilometers of cable around the underwater San Gregorio Fault system in Monterey Bay into an array of some 10,000 seismic sensors by interferometrically […]

With ultracold chemistry, researchers get first look at exactly what happens during a chemical reaction

Posted · Add Comment

In temperatures millions of times colder than interstellar space, researchers have performed the coldest reaction in the known universe. But that’s not all. In such intense cold, their molecules slowed to such glacial speeds, they could see something no one has been able to see before: the moment when two molecules meet to form two […]

Machine-guided engineering of AAV capsids

Posted · Add Comment

Taking a more systematic approach to the capsid protein-engineering problem, researchers mutated one by one each of the 735 amino acids within the AAV2 capsid, the best-known member of the AAV family, including all possible codon substitutions, insertions and deletions at each position. They generated a virus library containing about 200,000 variants and identified capsid […]
