Distinct Environmental DNA States Reveal Biodiversity and Transport Patterns Across Alpine Watersheds

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Environmental DNA (eDNA) exists in three states: membrane‐bound, adsorbed and dissolved. These states differ in persistence and degradation, strongly influencing the interpretation of eDNA data. Despite this, they have rarely been separated and analyzed independently from environmental samples.

Comparing Sol‐Gel Routes to Derive Mesoporous Bioactive Glasses Containing Tantalum for Hemostatic Application

Journal of the American Ceramic Society, Volume 109, Issue 10, October 2026.
ABSTRACT Mesoporous bioactive glasses (MBGs) are promising candidates for topical hemostatic powders because of their high surface area, negative zeta potential, and ion release promotes rapid blood–material interactions initiating coagulation.

Development and validation of a challenge model using geosmin‐spiked feeds to obtain off‐flavor compounds in tissues of Atlantic salmon, Salmo salar

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Fish produced within recirculating aquaculture systems may develop flavors not desired by end‐consumers, hereafter “off‐flavor,” which is largely attributed to geosmin accumulation in fish tissues. To develop methods for mitigating geosmin accumulation, a reliable and reproducible method of introducing geosmin in fish tissue is needed. Current

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2445-2465, October 2026.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Effect of Humidity on Ionisation and Ion Chemistry in Active‐Capillary Dielectric Barrier Discharge Ionisation

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Dielectric barrier discharge ionisation (DBDI) in an active‐capillary configuration (including the commercial SICRIT source) is widely used as a soft, ambient‐pressure ionisation method for vapours and gases, yet the role of water vapour in controlling reagent ion chemistry and analytical behaviour has not been mechanistically ...

Seawater consumption in dehydrated hooded seals (Cystophora cristata)

, 2012
Studies based on satellite-tracking show that hooded seals (Cystophora cristata) spend many months out in the open sea each year. When the seals are out in the open sea they have no access to fresh water. Experimental studies have showed that hooded seals drink seawater and that they have the capacity to produce urine with Na+ and cl- concentrations ...
