An old COVID-19 variant called A.30—which is exceedingly rare—“efficiently evades” antibodies induced by the Pfizer-BioNTech and AstraZeneca vaccines, ...
Scientists have mixed views on the variant, which a study recently called "heavily mutated" as it hasn't caused a recorded case in several months.
Biofouling — the accumulation of barnacles, plants and algae on ship hulls — is only getting worse as waters warm and as port congestion increases idle time, according to a recent I-Tech study. As it builds up, the biological material adds drag and reduces fuel efficiency, costing shippers money and releasing greenhouse gases unnecessarily. The ...
The evolution of the Delta variants is now a concern if they can develop relevant resistance to the vaccine antibody response. Researchers are concerned about how far it has evolved structures and proteins to circumvent cell defenses set from exposure to previous strains.
The number of idling vessels has roughly doubled in the past decade, in part due to port congestion, a recent study finds. Idling vessels are at higher risk of biofouling, especially in warm waters.
