Should mobile phones be allowed in hospitals?

A recent study suggests that newer mobile phones with improved handhold technology pose less risk to medical equipment. The researchers argue that a complete ban on mobile phone use in hospitals is no longer justified, and that patients' personal devices should be allowed in certain areas.

Stanford research points to chance as cause of genetic diseases in Ashkenazi Jews

Researchers found that mutations causing lysosomal storage diseases are no more common than other inherited diseases in the Ashkenazi Jewish population, indicating a lack of selective advantage. The study suggests that these disease-causing mutations were present in the ancestors of Ashkenazi Jews and were passed down through generations.

Ethnic bias in leading medical journals

The Lancet Commentary highlights the need for a radical transformation to reverse deeply embedded ethnic biases in leading medical journals. The journals prioritize research from the rich world, neglecting the health priorities of poor countries, and this bias affects the range of public debate.

Downward trend in UK deaths from CJD

The number of UK deaths from vCJD has been declining, with a stabilization in the rate of mortality. The disease's mortality rate is no longer increasing exponentially, but further confirmation is needed to determine if the epidemic is in permanent decline.

Scientists at Scripps Research Institute address mysteries of ozone in the human body

Researchers at Scripps Research Institute have found that the human body produces ozone as part of a mechanism to protect itself from bacteria and fungi. The discovery suggests a new role for neutrophils and antibodies in the immune system, potentially leading to new treatments for inflammatory diseases.

Screening test can help identify cancer survivors at risk for emotional distress

A new computerized survey has been developed to identify cancer survivors who are in greatest need of psychological counseling. The study found three key risk factors associated with psychological distress: dissatisfaction with physical appearance, poor physical health, and treatment with cranial radiation.
