Science can make blind mice see again and deaf mice hear — now scent-deprived mice can sniff their surroundings and smell for the first time, after a new gene therapy. It may be a while before this treatment percolates up to humans, but it’s a sign that gene therapy could restore smell in this rare but disorder.
Shutting down a brain receptor in mice — a receptor that also exists in humans — can block pathological rage, a new study says. We didn't realize that mice could experience pathological rage. But stopping it, and the impulsive violence that could result, would be a way to treat the types of aggression that are common in some neurological and psychological disorders in people.
In a new study with powerful implications for mental health, scientists hijacked the memories of lab mice, inducing them to form synthetic “hybrid memories” that were a combination of real experience and confused context. The work could eventually pave the way for false-memory or real memory manipulation in people with schizophrenia or post-traumatic stress disorder.
When you check in to a hospital in the future, along with checking your vitals and ordering a blood panel, your doctors may assign you a personal mouse. The immune-deficient creature will receive a transplant of your tissue, which will allow it to mimic your immune system, or maybe your specific type of cancer. Then doctors can try out a cocktail of drugs or gene therapies to see what might work on you.
A new drug that blocks a stress-provoked immune molecule in the brain can dramatically improve memory and learning abilities in mice, a new study says. A future pill that can suppress this molecule could show promise as a therapy for Alzheimer’s disease in humans, researchers say.

Researchers from University of Lausanne and EPFL University in Switzerland have developed genetically altered mice that have far higher physical endurance than regular mice. These "mighty mice" are able to run almost 50 percent further and for 20 minutes longer, while looking no different than their unaltered cousins, save for slightly larger muscles.
A new, finely tuned light-based treatment kills cancer cells in mice without harming the tissue around them, and could conceivably used to treat a wide range of human cancers, researchers say. The therapy is much more precise than other light-therapy methods attempted to date, and it has the potential to replace chemotherapy and radiation.
