Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

Meteoritics &Planetary Science, EarlyView.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Vertical distribution of natural radionuclides in soils

EPJ Web of Conferences, 2012
Low-level alpha spectrometry techniques using semiconductor detectors (PIPS) and liquid scintillation counters (LKB Quantulus 1220™) were used in order to determine the activity concentration of 238U, 232Th, 234U, 230Th, 226Ra, and 210Pb in soil samples.

Origin and formation of a chondritic xenolith in Krymka (LL3.2, breccia): Indications for a late formation of the accretionary breccia

Meteoritics &Planetary Science, EarlyView.
Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.

Natural Radionuclides in Ground Water

Journal of Geological Education, 1988
Most natural radioactivity in ground water originates from primordial radionuclides and their unstable decay products. An important secondary source is cosmic-ray production of radionuclides which are carried into the subsurface during ground water recharge.

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

New Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Comparison of four different in vitro assays for prediction of potential RBC antibody clinical significance

Transfusion, EarlyView.
Abstract Background The monocyte monolayer assay (MMA) uses monocytes, but it is known that antibody‐mediated hemolysis occurs in macrophages. Whether the use of macrophages would improve the predictive capacity of the MMA is unclear. Also, it is unclear if RBC alloantibodies contribute to hemolysis via antibody‐dependent cellular cytotoxicity (ADCC ...

Current Knowledge on Phytoremediation Potential of Industrial Hemp (Cannabis sativa L.) for PFAS and Heavy Metal Contaminated Soils

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT This review synthesizes current research on the phytoremediation potential of industrial hemp (Cannabis sativa L.) for heavy metals, including arsenic, aluminium, mercury, copper, lead, cadmium, nickel, and zinc, as well as per‐ and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals.” A structured and transparent ...
