Distanzabhängiger Energietransfer zwischen organischen Fluorophoren und einwandigen Kohlenstoffnanoröhren

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Wir zeigen, dass hybridisierte dsDNA eine senkrechte Ausrichtung zu SWCNTs einnimmt, und präsentieren eine abstandsabhängige Übertragung der Energie von Fluoreszenzfarbstoffen auf SWCNTs. Der Energietransfer von Kohlenstoffnanoröhren (CNET) folgt einer d−5‐Abhängigkeit mit einem charakteristischen Abstand von 7,4 nm (± 0,7 nm) für 50 % Energietransfer.

Drought reduces the value of both artificial and natural wetlands for gulls breeding in the Mediterranean region

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
The importance of artificial wetlands for waterbird conservation can be easily overestimated from count data alone. The value of extensive fish ponds as a breeding habitat depends on maintaining the availability of natural marshes as a foraging habitat. This requires reducing impacts from groundwater extraction. Given recent abandonment of aquaculture,

Comparison of ultrasound with computed tomography and whole‐body diffusion‐weighted MRI in prediction of surgical outcome using ESMO‐ESGO criteria in patients with tubo‐ovarian carcinoma: prospective ISAAC study

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 207-219, February 2026.
ABSTRACT Objective To test the non‐inferiority of extended abdominopelvic ultrasound examination compared with contrast‐enhanced computed tomography (CT) and whole‐body diffusion‐weighted magnetic resonance imaging (WB‐DWI/MRI) in discriminating preoperatively between resectable and non‐resectable disease based on the European Society for Medical ...

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

An arbuscular mycorrhiza from the 407‐million‐year‐old Windyfield Chert identified through advanced fluorescence and Raman imaging

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.
Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

Automated multivolume placental reconstruction using three‐dimensional power Doppler ultrasound and infrared camera tracking

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.
ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

Behind the lenses: Biases in the contribution of wildlife photography to biodiversity representation

People and Nature, Volume 7, Issue 2, Page 541-556, February 2025.
Abstract Nature‐related visual media has a significant impact on today's society by engaging the public in conservation problems and promoting pro‐environmental behaviours. Although major attention has been paid to how some types of visual media (e.g. documentaries) offer unrealistic portrayals of the natural world, biases on representation by wildlife
