Enzyme treatment of skin samples improves microbiome analysis
bacterial skin microorganism skin disease
2021/8/11
Healthy skin has a bacterial shield to protect against germs: the microbiome. This complex assembly of microorganisms was previously believed to be difficult to decipher. A team of researchers has now...
Lunar samples solve mystery of the moon's supposed magnetic shield
lunar magnetic field magnetization lunar soil
2021/8/9
Tests of glass samples gathered on Apollo missions show magnetization may result from impacts of objects like meteors, not as a result of magnetization from the presence of a magnetic shield.
Fossil pollen samples suggest vulnerability to extinctions ahead（图）
Fossil pollen samples suggest vulnerability extinctions ahead
2020/9/4
Reduced resilience of plant biomes in North America could be setting the stage for the kind of mass extinctions not seen since the retreat of glaciers and arrival of humans about 13,000 years ago, cau...
Rock Samples Indicate Water is Key Ingredient for Crust Formation
Rock Samples Indicate Water Crust Formation
2017/7/19
By examining the cooling rate of rocks that formed more than 10 miles beneath the Earth’s surface, scientists led by The University of Texas at Austin Jackson School of Geosciences have found that wat...
Evidence for the solar wind in lunar magmas: A study of slowly cooled samples of the Apollo 12 olivine basalt suite
hydrogen isotopes melt inclusions mare basalts SIMS lunar olivine
2017/4/10
While it is now recognized that the Moon has indigenous water and volatiles, their total abundances are unclear, with
current literature estimates ranging from nearly absent to Earth-like levels. Sim...
Advances in Imaging Secondary Ion Mass Spectrometry for Biological Samples
membrane organization chemical composition imaging NanoSIMS ToF-SIMS dynamic SIMS

Imaging mass spectrometry combines the power of mass spectrometry to identify complex molecules based on mass with sample imaging. Recent advances in secondary ion mass spectrometry have improved sens...
The electrical signature of rock samples exposed to hydrostatic and triaxial pressures
Electrical impedance spectroscopy fracturing carbonate amphibolite pressure
2015/9/28
The electrical signature of sedimentary (carbonate) and crystalline rock samples was studied in hydrostatic and triaxial pressure experiments up to 300 MPa. The aim was to establish a relation between...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
Pressure Stimulated Currents (PSC)in marble samples
Pressure Stimulated Currents (PSC)-Piezo Stimulated Current rocks marble-electricprecursors
2015/9/14
The electrical behaviour of marble samples from Penteli Mountain was studied while they were subjected to uniaxial stress. The application of consecutive impulsive variations of uniaxial stress to thi...
