Physicists Active Matter

Named a swirlonic state, the newly-discovered state of active matter is comprised of swirlons, formed by groups of active quasiparticles orbiting their common center of mass. Swirlons demonstrate a surprising behavior: in response to an external load they move with a constant velocity proportional to the applied force, just as …

Tianwen 1 Spacecraft

  Space around Mars is much busier than usual right now. The red planet made a close pass of Earth last summer, and numerous space agencies planned their Mars missions around this event. Now, the spacecraft are starting to show up — NASA’s Perseverance rover will land later this month, …

CERN Rare Decay

Physicists from the ATLAS (A Toroidal LHC ApparatuS) Collaboration at CERN’s Large Hadron Collider (LHC) have found first evidence of the Higgs boson decaying to a low-mass dilepton system (either an electron or a muon pair with opposite charge) and a photon. Known as Dalitz decay, this is one of …

Caffeine During Pregnancy

Caffeine consumed during pregnancy can change important brain pathways that could lead to behavioral problems later in life, according to new research from the Del Monte Institute for Neuroscience at the University of Rochester Medical Center. Caffeine is a known neuromodulator that is commonly consumed throughout pregnancy. Image credit: Poohchisa …

Coelacanths Study

The primitive-looking coelacanth has long been regarded as a ‘living fossil,’ with extant specimens looking very similar to fossils dating back to the Cretaceous period. But while the coelacanth’s body may have changed little, its genome tells another story. Latimeria chalumnae off Pumula on the KwaZulu-Natal South Coast, South Africa, …

First Flowering Plants

Flowering plants (angiosperms) are the most diverse of all land plants, becoming abundant in the Cretaceous period (145 to 66 million years ago) and achieving dominance in the Cenozoic (66 million years ago-present). However, the exact timing of their origin remains a controversial topic. To resolve this discrepancy, a team …

Helium Ion Microscope

New images of the SARS-CoV-2 coronavirus demonstrate the potential of the helium ion microscopy in bioimaging, especially for the imaging of interactions between viruses and their host organisms. This helium ion microscope image shows SARS-CoV-2 virus particles (blue). Image credit: N. Frese / Bielefeld University. Helium ion microscopy offers the …

NASA SPHEREx Telescope

  SpaceX already has a number of lucrative contracts with NASA thanks to its reusable Falcon 9 rocket, not least of which is the recently realized Commercial Crew Program. NASA isn’t just using SpaceX for crewed flights, though. The agency has just awarded SpaceX another cargo contract, this one to …

Minoan Linear Script

Linear A is a logo-syllabic script used for administrative purposes on Bronze Age Crete. Together with Cretan Hieroglyphic, it is one of two writing systems created by the Minoan civilization. Upon its template, the Mycenaeans later created the Linear B script to register their dialect of ancient Greek. Linear B …
