Older adult clumsiness linked to brain changes

For many older adults, the aging process seems to go hand-in-hand with an annoying increase in clumsiness — difficulties dialing a phone, fumbling with keys in a lock or knocking over the occasional wine glass while reaching for a salt shaker.

Obese Patients Trust Diet Advice from Overweight Physicians More than Normal Weight Physicians

When it comes to taking diet advice from a physician—size matters. This is according to a new study led by a team of researchers at the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins University School of Medicine who examined the impact of primary care physician BMI (body mass index) on their patients’ trust and perceptions of weight-related stigma.

Short chromosome ends in breast stem cells indicate susceptibility to breast cancer

A new paper published in Stem Cell Reports suggests that stem cell precursors with short chromosome ends (scientists call them telomeres) may indicate susceptibility to breast cancer. Telomeres are like caps on both ends of a chromosome and consist of repetitive nucleotide sequences. Telomere shortening have been implicated in aging and cancer, but a mechanism linking short telomeres in stem cells to cancer pathogenesis has not been proposed before.

Companies Pay Almost $6,000 Extra Per Year for Each Employee Who Smokes

A new study suggests that U.S. businesses pay almost $6,000 per year extra for each employee who smokes compared to the cost to employ a person who has never smoked cigarettes.

Researchers say the study is the first to take a comprehensive look at the financial burden for companies that employ smokers.
