Animal models are a necessary research tool for understanding how diseases develop and how therapies work in biological systems and can be credited for breakthroughs ranging from effective antibiotics to the COVID vaccines.

It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrollab

To ensure that vaccines provide strong and lasting immunization, it is often necessary to supplement the actual vaccine (antigen) with additives that stimulate the immune system: adjuvants. Today, only a few substances have been approved for use as adjuva

Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules that in the future could potentially be developed into a stroke recovery therapy. "Communication between nerve cells in large parts of the brain c

A new study from Mass Eye and Ear investigators shows that individuals who report tinnitus, which present as a ringing in the ears in more than one out of ten adults worldwide, are experiencing auditory nerve loss that is not picked up by conventional hea

Slow waves that usually only occur in the brain during sleep are also present during wakefulness in people with epilepsy and may protect against increased brain excitability associated with the condition, finds a new study led by researchers at UCL.

Microgels form a thin protective shell around a droplet until the temperature rises above 32 degrees. Then the microgels shrink and the droplet dissolves in the surrounding liquid. A study by researchers from the University of Gothenburg now reveals the u
