MIT scientists kept growing ocean microbes that clung to test tubes; the sticky share rose from 6% to 85%, revealing a hidden way they release carbon into water
Prochlorococcus, a small but abundant marine microbe, was thought to exist mainly as solitary cells. New research findings reveal that it can form biofilms and attach to particles. This discovery has implications for understanding the biological carbon pump in the oceans. While these microbes can switch between free-floating and attached forms, they contribute significantly to carbon transport. Scientists are further investigating the role of attached Prochlorococcus in marine ecosystems.
Delhi-NCR PUC tests to get tamper-proof technology under govt upgrade plan, nationwide rollout to follow
A new technology-based system for vehicle emission testing will first be introduced in Delhi-NCR before being extended to other parts of the country. The revised standards require testing instruments to authenticate their readings and send them directly to a central server, while restricting the ability of PUC centre computers to alter test results.
