Researchers at the University of Florida have developed a promising new gene therapy against multiple sclerosis (MS). Tested in mice, the treatment was effective in preventing the mouse equivalent of the disease, and almost completely reversed the symptoms in animals already suffering from it.

Researchers at Duke University have combined two techniques for fighting cancer. In one case, the mouse’s immune system not only destroyed the tumor, but stayed strong enough to ward off a later injection of cancer cells, raising hopes that the strategy could one day lead to a viable cancer vaccine.

Scientists have developed a technique that lets them directly control physical movements in mice. Using magneto-thermal stimulation, they activated sections of the brain that caused mice to run, turn or stop, which could eventually lead to new therapies for brain disorders or even mental illness.

When it needs to pump more blood, the heart can grow in response to exercise and pregnancy, but after a heart attack, swelling can lead to further complications. Now scientists have found that a protein called cardiotrophin 1 (CT1) can trick the heart into the good kind of growth and reduce the bad.

A new study from Imperial College London has successfully found a way to target specific thyroid hormones in the brain and manipulate appetite in mouse subjects with no side effects.

How exactly do we overcome the powerful urge to sleep? Caltech researchers may have identified the neural circuit responsible in mice, and their findings could help treat people with various sleep disorders.

Last year, a proof-of-concept study described how the CRISPR-Cas9 gene-editing tool could be used to eliminate HIV from infected cells. In a potential step towards a permanent cure, the team has shown that the technique keeps the virus from spreading, and in latent cases, rips it from its hideout.

The CRISPR-Cas9 genome editing system could help fight cancer, and now, researchers have used the tool to target what they call cancer’s command center, in a treatment that’s been shown in mice to shrink aggressive tumors and increase survival rates, without harming healthy cells.

New research could mean that a pill to provide some of the same health benefits as exercise could eventually move from fantasy to reality. Scientists have found suppressing a particular protein can enhance muscle mass and help obese people reduce their risk of a number of health concerns.

Researchers have been able to restore cell function of old mice to that of younger mice. The team says an anti-aging drug could be developed in a few years, and the treatment also shows promise in reversing DNA damage caused by radiation exposure – good news for cancer battlers or space travelers.
