Scientists untangle the challenging complexities of radiocarbon in ice cores
ANSTO scientists, Dr. Andrew Smith, Dr. Quan Hua and Dr. Bin Yang have contributed to a paper that elucidates how in situ cosmogenic radiocarbon (14C) is produced, retained and lost in the top layer of compacting snow (the "firn layer") and the shall.....»»
Nonnative plants are a major force behind global insect invasions, study finds
In an article in the journal BioScience, an international team of researchers led by Dr. Cleo Bertelsmeier from the University of Lausanne, Switzerland, argues that the global spread of nonnative plants is a key factor driving the growing number of i.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
Biofilms study reveals how multiple bacteria species manage to coexist
Biofilms—slimy communities of bacteria—grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species,.....»»
Rare ultra-luminous nova spotted in the Small Magellanic Cloud
