The Earth System: An Introduction to Earth Systems Science [PDF]
Eos, Transactions American Geophysical Union, 1999 The atmosphere, hydrosphere, biosphere, and solid Earth are the basic components of the Earth system. These different components are not separate entities; instead they interact over a broad range of spatial and temporal scales. Determining how various internal and external influences impact each component of the Earth system individually is ...

The analysis of ion flow between the human body and local ground [PDF]
, 2012 The project was designed to get a better sense of the phenomenon referred to as Earthing. Earthing is defined as the process where the human body is in contact with the earth and can freely transfer ions between the Earth and itself.

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity
FEBS Open Bio, EarlyView.Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.
