Three‐dimensional swimming behavior and activity of a mesopelagic fish

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2677-2690, December 2022., 2022
Abstract Knowledge of the three‐dimensional behavior and activity patterns of mesopelagic fishes is crucial for understanding their role in ecological and biogeochemical processes in the ocean. We here show that the use of submerged stationary echosounders enables detailed analysis of three‐dimensional swimming behavior of small mesopelagic fishes in ...

Comorbidity trajectories before and after the diagnosis of heart failure: A UK Biobank cohort study

open access: yesEuropean Journal of Heart Failure, EarlyView.
Time of diagnosis of comorbidities in relation to heart failure. COPD, chronic obstructive pulmonary disease; MI, myocardial infarction. Abstract Aims Heart failure (HF) is frequently associated with multiple comorbidities. We aimed to define their trajectory of accrual to identify opportunities for disease prevention. Methods and results We identified

Oceanic lobate ctenophores possess feeding mechanics similar to the impactful coastal species Mnemiopsis leidyi

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2706-2717, December 2022., 2022
Abstract Lobate ctenophores are often numerically dominant members of oceanic epipelagic and midwater ecosystems. Despite this, little is known about their trophic ecology. Multiple, co‐occurring species are often found in these ecosystems and appear to feed similarly via feeding currents that entrain prey.

Nonenzymatic Carboxylate Phosphorylation in Water

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The phosphorylation of carboxylic acids to acyl phosphates is a recurring reaction in the core of microbial metabolism, a set of processes thought to date back to the origins of life. This study shows that carboxylate phosphorylation occurs in water without enzymes or adenosine triphosphate (ATP), enabled by diamidophosphate and nitrite.

Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day
