Magnetosomes could be protective shields against metal stress in magnetotactic bacteria
(Nature, 2020-07)
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic ...
Microfluidic chip with pillar arrays for controlled production and observation of lipid membrane nanotubes
(Royal Society of Chemistry, 2020-08-07)
Lipid membrane nanotubes (NTs) are a widespread template forin vitrostudies of cellular processes happening at high membrane curvature. Traditionally NTs are manufactured one by one, using sophisticated membrane ...
Magnetic Oscillations Induced by Phonons in Non-Magnetic Materials
(Nature, 2020-01-24)
The authors show that, similarly to electrons, in the presence of spin-orbit coupling, phonons can induce an effective magnetic oscillation even in non-magnetic materials, and therefore can act as an additional spin-flipping ...
Magnetotactic bacteria for cancer therapy
(American Institute of Physics, 2020-08-21)
Magnetotactic bacteria (MTB) are aquatic microorganisms that are able to biomineralize membrane-enclosed magnetic nanoparticles called magnetosomes. Inside the MTB, magnetosomes are arranged in a chain that allows MTB to ...
Investigating the Size and Microstrain Influence in the Magnetic Order/Disorder State of GdCu2 Nanoparticles
(MDPI, 2020-06-05)
A series of GdCu [Math Processing Error] nanoparticles with controlled sizes ranging from 7 nm to 40 nm has been produced via high-energy inert-gas ball milling. Rietveld refinements on the X-ray diffraction measurements ...
Differences in biochemical, gas exchange and hydraulic response to water stress in desiccation tolerant and sensitive fronds of the fern Anemia caffrorum
(Wiley, 2021-08)
Desiccation tolerant plants can survive extreme water loss in their vegetative tissues. The fern Anemia caffrorum produces desiccation tolerant (DT) fronds in the dry season and desiccation sensitive (DS) fronds in the wet ...
Combined dynamics of the 500–600 nm leaf absorption and chlorophyll fluorescence changes in vivo: Evidence for the multifunctional energy quenching role of xanthophylls
(Elsevier, 2021-02-01)
Carotenoids (Cars) regulate the energy flow towards the reaction centres in a versatile way whereby the switch between energy harvesting and dissipation is strongly modulated by the operation of the xanthophyll cycles. ...
A Two-Sample Mendelian Randomization Analysis Investigates Associations Between Gut Microbiota and Celiac Disease
(MDPI, 2020-05-14)
Celiac disease (CeD) is a complex immune-mediated inflammatory condition triggered by the ingestion of gluten in genetically predisposed individuals. Literature suggests that alterations in gut microbiota composition and ...
The Performance of the Magneto-Impedance Effect for the Detection of Superparamagnetic Particles
(MDPI, 2020-03-31)
The performance of magneto-impedance sensors to detect the presence and concentration of magnetic nanoparticles is investigated, using finite element calculations to directly solve Maxwell’s equations. In the case ...
IBERLID: A lead isotope database and tool for metal provenance and ore deposits research
(Elsevier, 2021-10)
[EN] Although sometimes controversial, the use of Pb isotope data in geological research of ore deposits and metal provenance studies in archaeology has proved a useful tool for investigation of the relations between ore ...
