SARS-CoV-2 variants and the future of the pandemic, the tough problem of space junk and India’s COVID-vaccine crunch is putting global supplies at risk.
The heterochromatin protein HP1 has an essential role in establishing several features of the 3D nuclear organization of the genome during early embryonic development in Drosophila.
A two-tiered dynamic design strategy achieves topological transformations of two-dimensional polymeric cellular microstructures in a reversible and temporally controllable manner through exposure to different liquids.
The pressure dependence and magnetic field dependence of the specific heat of a quantum magnet, SrCu2(BO3)2, demonstrate that its phase diagram contains a line of first-order transitions terminating at a critical point, in analogy with water.
A model for eruptions resulting in caldera collapse reconciles observations of quasi-periodic stick–slip events along annular faults and the large erupted volumes characteristic of such events, highlighting the role of topography-generated pressures.
Biochemical and genetics studies identify CRL4AMBRA1 as the ubiquitin ligase that has a key role in regulating the stability of D-type cyclins during cell-cycle progression.
Genomic analyses of human populations in the Pacific provide insights into the peopling history of the region and reveal episodes of biological adaptation relating to the immune system and lipid metabolism through introgression from archaic hominins and polygenic adaptation.
