With any pesticide, over-use can have harmful effects on the environment. 

DDT has not been used in America for over four decades but Rutgers scholars say that exposure to DDT may also increase the risk and severity of Alzheimer's disease in some people, particularly those over the age of 60. 

World War II had consequences for continental Europeans. Living in a war-torn country increased the likelihood of a number of physical and mental problems later in life, according to a paper by economists. 

When you think of treating urinary incontinence in senior women, what is the first thing that comes to mind?

Probably not dancing. But maybe it will work, and it sounds like fun. 

For a study of potential benefits of dancing (and virtual reality), researchers added a series of dance exercises via a video game console to a physiotherapy program for pelvic floor muscles. The results of the small study (24 participants) was a greater decrease in daily urine leakage than for the usual program (so, an improvement in effectiveness) as well as no dropouts from the program and a higher weekly participation rate (an increase in compliance). 

Medical researchers have found a way to reverse a cause of aging in animals - and it doesn't involve starvation. 

The work relates to mitochondria, which are our cells' battery packs and give energy to carry out key biological functions, and a series of molecular eventsthat  enable communication inside cells between the mitochondria and the nucleus. As communication breaks down, aging accelerates. 

Ignoring meaningless platitudes like 'age is all in your mind', age is more than a number of years. 'You are as young as you feel' may be more apt because factors such as health, cognitive function and disability rates are important ways to measure age in all its dimensions.

International Institute for Applied Systems Analysis
population researchers Warren Sanderson and Sergei Scherbov seek to reorient the way demographers study population aging, providing a new toolbox of methodologies for demographers to better understand the impacts of an aging population on society, by measuring based instead on characteristics of people that change with age, including life expectancy, health, cognitive function, and other measures. 

The concept of permanent neurological injury is so 20th century.

Instead, there has been gradual recognition of the brain's potential for long-term regeneration and reorganization and so rehabilitations strategies are undergoing radical changes. The potential for five new translational interventions was examined in an recent Neurology Clinical Practice article.

It's said that being an astronaut is no longer a bold endeavor. The job works program nature of NASA and a no-risk approach to missions by government has meant a drop in prestige among the public. It used to be risky and that captured the public's imagination.

Some day, if presidents stop canceling the space programs of their predecessors, man may leave orbit again, and astronauts will gain some new respect, because even if the mission is successful astronauts are paying a price - their cells are aging faster in microgravity.

Engaging in some Do It Yourself projects or gardening can cut the risk of a heart attack/stroke and prolong life by as much as 30 per cent among the 60+ age group, indicates a new paper. 

They might seem like routine activities but they are as good as exercise, and more fun, which is ideal for older people who don't often do that much formal exercise, according to the scholars who based their findings on almost 4,000 sixty-year-olds in Stockholm, Sweden, who had their cardiovascular health tracked for around 12 years. At the start of the study, participants took part in a health check, which included information on lifestyle, such as diet, smoking, and alcohol intake, and how physically active they were.

A new paper says that babies can tell when something is wrong — as early as 18 months.

Neurons that process sensory information such as touch and vision are arranged in precise, well-characterized maps that are crucial for translating perception into understanding.  A new study finds that, in mice brains, the actual act of birth in mice causes a reduction in serotonin, triggering sensory maps to form.
