Two-dimensional electron liquids

Researchers have discovered a novel form of superconductivity in two-dimensional electron liquids, characterized by the presence of quantum point contacts. These tiny channels enable the flow of superconducting currents, but with a twist: the spin degree of freedom is broken, allowing for new types of electron transport.

Little fire ant control is a big job

The University of Guam Entomology Lab has received a $50,000 USDA Forestry grant to implement control procedures for the invasive little fire ant (Wasmannia auropunctata) on Guam. The team aims to demonstrate that these ants can be controlled through ongoing funding.

Study sheds light on asthma and respiratory viruses

A new study found that people with asthma have a similar immune response to respiratory viruses as those without asthma, suggesting another aspect of the immune system is at play. The researchers compared the key immune response to viruses in the lungs and breathing passages, finding no significant differences.
