Larger dogs have better short-term memory and self-control than smaller breeds, according to research led by the UA's Arizona Canine Cognition Center.

Brine discharged from the Carlsbad Desalination Plant raises offshore salinity levels more than permitted, but researchers found no direct local impacts on sea life.

Selective serotonin reuptake inhibitors (SSRIs) lift the fog of depression for many people. But for around a third of people with major depressive disorder, SSRIs don’t make much of a difference. Now, researchers from the Salk Institute have pinned down a possible reason why—the neurons in at least some of these patients’ brains may become hyperactive in the presence of the drugs.

Warmer water temperatures, combined with low-level exposure to chemicals already known to be harmful to aquatic life, influence the expression of genes in the offspring of an abundant North American fish species - and threaten organisms whose sex determination is sensitive to water temperature.

Atomic and molecular information about the workings of the highly potent antibodies may provide insights to prevent these serious and sometimes deadly lung infections.

A laboratory-created microscopic network of fibers helped researchers understand how white blood cells capture and even kill bacteria, offering insight into the effectiveness of antibiotics in the future.

MIT cancer biologists have discovered a new mechanism that lung tumors exploit to promote their own survival: These tumors alter bacterial populations within the lung, provoking the immune system to create an inflammatory environment that in turn helps the tumor cells to thrive.

A molecular network that controls the deposition of connective tissue has been decrypted, and could in future provide a new way to treat organ scarring.

Research in animal models and patient tissues has identified a new molecular pathway in the liver that suggests a commonly used anti-rejection medication could be repurposed to treat certain liver cancers.

Ageing can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus, finds a new study by Cardiff University.
