Australian museum ’s plan to cut research draws fire from scientists
A plan by one of Australia’s major natural history museums to reduce and “reimagine” the roles of its research and curatorial staff is drawing fierce criticism from scientists in Australia and abroad.
Leaders of the South Australian Museum (SAM) in Adelaide say the proposed changes, unveiled in late February, are needed to address financial shortfalls and help the 168-year-old museum become more “sustainable, relevant, and accessible … for the 21st century.” David Gaimster, SAM’s CEO, has told Australian media that the museum is “not a university” and suggested that, in the future, its researchers s...

Characteristics and health implications of fine particulate matter near urban road site in Islamabad, Pakistan
Environ Res. 2024 Apr 2:118862. doi: 10.1016/j.envres.2024.118862. Online ahead of print.ABSTRACTThe escalating issue of air pollution has become a significant concern in urban regions, including Islamabad, Pakistan, due to the rise in air pollutant emissions driven by economic and industrial expansion. To gain a deeper understanding of air pollution, a study was conducted during winter 2022-2023, assessing physical, chemical, and biological factors in Islamabad. The findings revealed that the average concentration of fine particulate matter (PM2.5) was notably greater than the World Health Organization (WHO) guidelines, r...

Threat of mining to African great apes
Sci Adv. 2024 Apr 5;10(14):eadl0335. doi: 10.1126/sciadv.adl0335. Epub 2024 Apr 3.ABSTRACTThe rapid growth of clean energy technologies is driving a rising demand for critical minerals. In 2022 at the 15th Conference of the Parties to the Convention on Biological Diversity (COP15), seven major economies formed an alliance to enhance the sustainability of mining these essential decarbonization minerals. However, there is a scarcity of studies assessing the threat of mining to global biodiversity. By integrating a global mining dataset with great ape density distribution, we estimated the number of African great apes that sp...

To be or not to be a cytochrome: electrical characterizations are inconsistent with Geobacter cytochrome ‘nanowires’
Geobacter sulfurreducens profoundly shapes Earth’s biogeochemistry by discharging respiratory electrons to minerals and other microbes through filaments of a two-decades-long debated identity. Cryogenic electron microscopy has revealed filaments of redox-active cytochromes, but the same filaments have exhibited hallmarks of organic metal-like conductivity under cytochrome denaturing/inhibiting conditions. Prior structure-based calculations and kinetic analyses on multi-heme proteins are synthesized herein to propose that a minimum of ~7 cytochrome ‘nanowires’ can carry the respiratory flux of a Geobacter cell, which ...

Essential bioactive competence of laminarin ( β-glucan)/ laminaran extracted from Padina tetrastromatica and Sargassum cinereum biomass
This study was conducted to extract laminarin-enriched solvent extracts from Padina tetrastromatica and Sargassum cinereum and to evaluate their anticancer activity against the HeLa cell line in vitro (MTT assay). Furthermore, their toxicity was determined through a zebra fish model study. P. tetrastromatica and S. cinereum biomasses have a higher concentration of essential biomolecules such as carbohydrates, protein, and crude fiber, as well as essential minerals (Na, Mg, K, Ca, and Fe) and secondary metabolites. Methanol extracts, in particular, contain a higher concentration of vital phytochemicals than other solvent ex...

Mineral patterns in hair: A decisive factor between reproducible and repeat breeder dairy cows
by Hyun-Joo Lim, Seunghoon Lee, Woncheoul Park, Eungwoo Park, Jae Gyu Yoo
Reproduction, especially impregnation, is a critical aspect of dairy cow management that directly influences herd milk productivity. We conducted a noninvasive hair mineral assay to compare the mineral profiles of two dairy cow groups: reproducible and repeat breeder, by investigating the levels o f 11 essential minerals (Ca, Mg, Na, K, Fe, Cu, Mn, Zn, Cr, Se, and P) and 6 toxic elements (Hg, Pb, Cd, Al, As, and Ni) in both groups. We also conducted principal component and correlation matrix analyses to compare hair mineral patterns between the grou...

Radioactive and mineralogical assessment of mediterranean black sands: a systematic analysis and health risk evaluation
This study investigates the naturally occurring radionuclides in Egyptian black sands collected from the Mediterranean Sea Coast, an area rich in sediments from the White Nile, Blue Nile, and Atbara rivers. The black sands mainly comprise two groups of minerals: the gangue group, consisting of quartz, feldspar, amphiboles, pyroxenes, epidote, and micas, and the economic minerals group, which includes magnetite, garnet, zircon, monazite, and uncommon commercial minerals like thorite. A gamma spectrometry with a NaI (Tl) detector was employed to analyze black sand samples for the presence of radionuclides. Additionally, radi...
