In some women abnormally high levels of the common and pervasive chemical perchlorate may lead to adverse effects in their offspring. The study in the Journal of Clinical Endocrinology  &  Metabolism says is the first of its kind to shed light on the possible harmful side effects of perchlorate in mothers and their children.  

A long-term, large-scale population-based study of individuals aged 55 years or older in the general population researchers has found a four-fold increased risk of developing dementia or Alzheimer's disease (AD) if they were diagnosed even with mild cognitive impairment (MCI).

Compared to cognitively healthy individuals, other risk factors including older age, positive APOE-ɛ4 status, low total cholesterol levels, and stroke, as well as specific MRI findings were associated with an increased risk of developing MCI.  

A new hand-held device uses lasers and sound waves to accurately measure how deep a melanoma tumor extends into the skin, providing valuable information for treatment, diagnosis or prognosis. 

Studies have shown that being a 'night owl', like people who claim to multitask, is something of a myth - people perform better in the mornings whether they are night owls or morning people people - and a new study finds that becomes more pronounced with age.

Older adults tested in the morning not only perform better on demanding cognitive tasks but also activate the same brain networks responsible for paying attention and suppressing distraction as younger adults, according to a study in Psychology and Aging. The authors say this some of the strongest evidence yet that there are noticeable differences in brain function across the day for older adults.

Baby Boomers, a trend in births that happened when soldiers returned home from World War II, started off their lives being critical of American culture and having a sense of entitlement about how the world should reshape itself to suit them. But now, compared to Generation X and Millennials, they may be the last group with a true sense of responsibility.

Few seem to enjoy it, they instead know they will be worse off later if they don't make the effort now.

Muslim clerics get a bad rap in an interconnected world. It was once possible to be anti-women, anti-medicine and anti-science without much notice - just control the media - but today that is a difficult task.

In some parts of the world, imams, Islamic school teachers and traditional rulers are making a positive difference and pushing back the vestiges of conspiracy theories about medicine. In defiance of past teaching, they are working with doctors, journalists and polio survivors to turn the tide against polio vaccine rejection in northern Nigeria.
