The conductivity of living organs, such as the heart, could be imaged non-invasively using quantum technology, which has the potential to revolutionize the diagnosis and treatment of atrial fibrillation. Atrial fibrillation (AF) is a heart condition that causes an irregular and abnormally fast heart rate, potentially leading to blood clots, stroke, heart failure and other heart-related complications. While the causes of AF are unknown, it affects around one million people in the UK with cases predicted to rise at a great cost to the NHS.

Currently, AF is commonly diagnosed using an electrocardiogram (ECG), but this can only be done during an episode, so complementary means of diagnosis are needed.

AF is treated thr...

Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study by researchers at the Stanford University School of Medicine.

The researchers also found that elderly mice regained youthful strength after their existing muscle stem cells were subjected to the rejuvenating protein treatment and transplanted back into their bodies.

The proteins, known as Yamanaka factors, are commonly used to transform an adult cell into what are known as induced pluripotent stem cells, or iPS cells...

In a study involving thousands of participants, a new blood test detected more than 50 types of cancer as well as their location within the body with a high degree of accuracy, according to an international team of researchers led by Dana-Farber Cancer Institute and...

Coughing fits, anxiety and paranoia are three of the most common adverse reactions to cannabis, according to a recent study by Washington State University researchers. They surveyed > 1,500 college students on the type and frequency of adverse reactions they had experienced while using cannabis for their study in the Journal of Cannabis Research. They also collected information on the students’ demographics, personality traits, cannabis use patterns and motives for using the drug.

“There’s been surprisingly little research on the prevalence or frequency of various adverse reactions to cannabis and almost no research trying to predict wh...
