Researchers at Karolinska Institutet have investigated the association between certain immune markers in neonates and the risk of later developing autism spectrum disorder (ASD). They found that mid-levels of a classical marker of inflammation, C-reactive protein, were associated with the lowest risk for ASD – whereas too much or not […]

Radiation and chemotherapy are designed to kill cancer cells. But for many patients, cancer cells can survive even after being hit with high doses of chemotherapy or radiation. To make treatment more effective, scientists are focusing on ways to tweak the inner machinery of cancer cells to make them more […]

A new UC Riverside study shows flame retardants found in nearly every American home cause mice to give birth to offspring that become diabetic. These flame retardants, called PBDEs, have been associated with diabetes in adult humans. This study demonstrates that PBDEs cause diabetes in mice only exposed to the […]

A novel computational method that quantifies for the first time the coordination level between different genes reveals a new hallmark of aging which could require a change of course in current efforts to develop healthy-aging treatments. Although all humans share similar changes during aging such as gray hair, wrinkles, and […]

Cancer affects millions and millions of people every year. Scientists would like to encourage our own immune system to attack it, which is why immunotherapies are probably the most promising treatments for cancer. Now scientists at UCL developed a new kind of immunotherapy, which launches a two-pronged attack against melanoma, […]

Dementia is in the cards for many. It is a common typically age-related cognitive decline, which is a burden for the patients and their families. Dementia is an incurable condition and one of the most common causes of death as well. It is estimated that around 50 million people globally […]
