Let's do what we can to preserve science (which is an international endeavour) and support our US colleagues until the US gets rid of Trump!

Some observations from the 2024 #GoogleScholar citation metrics:

1. #ScienceMag is no longer top three (but #NatureMag is still at the top).

2. Articles about #AI or #climateScience seem more highly cited, even outside #STEM (e.g., #philosophy).

#ScienceMag Shot noise in a strange metal https://www.science.org/doi/10.1126/science.abq6100 strange metals have not quasiparticles; hence shot noise is reduced, as observed in a heavy fermion material YbRh₂Si₂ compared with the values measured in a comparable gold nanowire and with theory expectations.

#ScienceMag Phosphatidylinositol 3,5-bisphosphate facilitates axonal vesicle transport and presynapse assembly https://www.science.org/doi/10.1126/science.adg1075 A crucial mechanism that mediates the delivery of synaptic vesicle and active zone proteins to developing synapses. Precursor vesicles are distinct from conventional secretory organelles, endosomes, and degradative lysosomes and are transported by coincident detection of PI(3,5)P2 and active ARL8 via kinesin KIF1A to the presynaptic compartment.

#ScienceMag Torture-testing fusion reactor walls https://www.science.org/content/article/news-glance-endangered-plants-diversity-clinical-trials-and-testing-fusion-reactor
A facility in Granada, Spain, to simulate how materials are degraded by a bombardment of neutrons. The €700 million International Fusion Materials Irradiation Facility-Demo Oriented Neutron Source (IFMIF-DONES), funded by the European Union, will allow researchers to test the performance of neutron-resistant materials. The EU hopes to use the findings to help design a demonstration fusion power plant generating up to 500 megawatts by the 2050s.

#ScienceMag Comparative transcriptomics reveals human-specific cortical features https://www.science.org/doi/full/10.1126/science.ade9516 snRNA-seq offers a characterization of cellular diversity of brain regions. Middle temporal gyrus cell types are largely conserved across approximately 40 million years of primate evolution. Human-specific differentially expressed genes contribute to human-specialized cortical function.

#ScienceMag Direct observation of glycans bonded to proteins and lipids at the single-molecule level https://www.science.org/doi/full/10.1126/science.adh3856 Many proteins have sugar chains attached. Glycans attached to peptides and lipids can be imaged directly using single-molecule atomic force microscopy. The submolecular imaging resolution corroborated by quantum mechanical modeling unveils whole structures and attachment sites of glycans in glycopeptides, glycolipids, N-glycoproteins, and O-glycoproteins densely decorated with glycans.
