Researchers have analyzed water samples collected during two expeditions aboard the research icebreaker Polarstern to investigate how life and changing conditions on the Antarctic continental shelf affect carbon carried into the deep ocean. Published in Nature Communications, the study reveals a surprising finding: Despite intense biological activity and major changes in the water masses, the amount and make-up of dissolved organic matter remain almost unchanged.

Poles of bacteria imaged in fine detail for the first time

The poles, or ends, of rod-shaped bacteria have been imaged at molecular resolution for the first time in a new study led by UCL (University College London) researchers. The study, published in the journal Nature Communications, used a new technique to keep live bacteria in place

New approach boosts plastic-eating enzyme's activity nearly tenfold

Researchers from King's College London and Rutgers University in New Jersey created a modified enzyme (a protein that speeds up chemical reactions) that breaks down polyethylene terephthalate (PET) plastic 10 times quicker, using 10 times less enzyme. They accomplished this just

Repeatable laser measurements reveal 'forbidden' vibrations in single molecules without destroying them

The possibility of controlling "forbidden" excitations of vibrations in molecules could form the basis of extremely accurate clocks, quantum bits and precise tests of the fundamental laws of physics. Researchers at the University of Basel have now identified and controlled such "

Ph.D. completion depends on reciprocal mix of candidate, supervision and institution, review finds

Low Ph.D. completion rates remain a challenge in higher education, reflecting a complex interplay of individual, supervisory and institutional factors. Despite extensive research, few reviews have investigated the factors related to Ph.D. completion, with most focusing on isolate
