Phosphorus-32, a Clinically Available Drug, Inhibits Cancer Growth by Inducing DNA Double-Strand Breakage

PLoS ONE, 2015
Radioisotopes that emit electrons (beta particles), such as radioiodine, can effectively kill target cells, including cancer cells. Aqueous 32P[PO4] is a pure beta-emitter that has been used for several decades to treat non-malignant human ...

A Dual Isotope Protocol to Separate the Contributions to Phosphorus Content of Maize Shoots and Soil Phosphorus Fractions from Biosolids, Fertilizer and Soil

Current Agriculture Research Journal, 2018
Separation of the phosphorus (P) contributions from soil, fertilizer and biosolids to plants has not been possible without the aid of radioisotopes. Dual labelling of soil with 32P and fertilizer with 33P isotopes has been used to partition the sources ...

Coastal sediments record decades of cultural eutrophication in Tampa Bay, Florida, USA

Ecological Indicators
Phosphorus (P) sustainability is a complex problem – it is a limited resource critical for agricultural productivity, but fertilizer production generates extensive phosphogypsum waste and can impair downstream water quality.

Impact of pyrolysis temperature on phosphorus plant availability in biochar—A pot experiment using 33P dilution

Journal of Environmental Quality, EarlyView.
Abstract Separation and pyrolysis of the solid fractions of biogas digestate and animal slurry offer potential solutions to environmental and logistical challenges associated with direct slurry application as fertilizer. However, thermochemical transformations during pyrolysis typically reduce P availability.

A Comprehensive Study of Quantum Dots: Ranging From Synthesis to Applications in Electrochemical Biosensors in the Detection of Biomolecules, Gastrointestinal Diseases, and Electrophysiology

Nano Select, EarlyView.
Quantum dots (QDs) typically refer to extremely small semiconductor particles, often no larger than 10 nm. The development of efficient biosensors for the sensitive and selective detection of biomolecules is essential for fundamental research in analytical chemistry, biomedicine, clinical diagnosis, and electrophysiology.

Petrography of phosphates in CI and CY carbonaceous chondrites

Meteoritics &Planetary Science, EarlyView.
Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...

Potential Application of a Water‐Soluble Fullerene C60 Decorated with Diethylene Glycol in Treatment of Osteoarthritis

Advanced NanoBiomed Research, Volume 5, Issue 9, September 2025.
A new ethoxyethanol derivative of iminofullerene, F2, is synthesized and labeled with 99mTc to produce 99mTc‐F2. In vitro, compound F2 inhibits the activation of primary mouse bone marrow‐derived macrophages stimulated with lipopolysaccharide. Moreover, 99mTc‐F2 is selectively enriched in the injured joints of mice. Inflammatory macrophages play a role

Biological, Biogeochemical, Bio‐Optical, and Physical Variability of the Southern Ocean Along 150°W and Its Relevance to the Great Calcite Belt

Global Biogeochemical Cycles, Volume 39, Issue 8, August 2025.
Abstract We report hydrographic and biogeochemical measurements from a meridional transect performed along 150°W, 30°S to 60°S in the Southern Ocean, plus Polar waters to the east. Both of these areas are sites of annual high‐reflectance features in ocean color remote sensing, which were heretofore never confirmed with in situ measurements.

Constraining the Source Craters of Apollo Impact Melts

Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.
Abstract Interpreting the age distribution of Apollo samples to determine the early bombardment history of the Moon has been fraught with controversy, and the question of how much material from large impact basins such as Imbrium is present in the Apollo sample collection remains unresolved. Here, we model impact melt production and transportation over
