Chiral monoterpenes reveal forest emission mechanisms and drought responses [PDF]
Nature, 2021 Abstract Monoterpenes (C 10 H 16 ) are emitted in large quantities by vegetation to the atmosphere (>100 TgC year −1 ), where they readily react with hydroxyl radicals and ozone to form new ...

Satellites reveal Earth's seasonally shifting dust emission sources
Science of The Total Environment, 2023 Establishing mineral dust impacts on Earth's systems requires numerical models of the dust cycle. Differences between dust optical depth (DOD) measurements and modelling the cycle of dust emission, atmospheric transport, and deposition of dust indicate large model uncertainty due partially to unrealistic model assumptions about dust emission frequency.

Spectroscopy of a mesospheric ghost reveals iron emissions
Nature Communications, 2023 AbstractMesospheric Green emissions from excited Oxygen in Sprite Tops (ghosts) are infrequent and faint greenish transient luminous events that remain for hundreds of milliseconds on top of certain energetic sprites. The main hypothesis to explain this glow persistence is the long lifetime of excited atomic oxygen at 557.73 nm, a well-known emission ...

Transcriptomics in cancer revealed by Positron Emission Tomography radiomics [PDF]
Scientific Reports, 2020 AbstractMetabolic images from Positron Emission Tomography (PET) are used routinely for diagnosis, follow-up or treatment planning purposes of cancer patients. In this study we aimed at determining if radiomic features extracted from18F-Fluoro Deoxy Glucose (FDG) PET images could mirror tumor transcriptomics.

Satellite data reveal a common combustion emission pathway for major cities in China [PDF]
Atmospheric Chemistry and Physics, 2019 Extensive fossil fuel combustion in rapidly developing cities severely affects air quality and public health. We report observational evidence of decadal changes in the efficiency and cleanness of bulk combustion over large cities in mainland China ...

Neutron Star Mergers and the Quark Matter Equation of State [PDF]
EPJ Web of Conferences, 2022 As neutron stars merge they can approach very high nuclear density. Here, we summarized recent results for the evolution and gravitational wave emission from binary-neutron star mergers using a a variety of nuclear equations of state with and without a ...

High-fidelity carbon dots polarity probes: revealing the heterogeneity of lipids in oncology
Light: Science & Applications, 2022 Polarity is an integral microenvironment parameter in biological systems closely associated with a multitude of cellular processes. Abnormal polarity variations accompany the initiation and development of pathophysiological processes.
