NASA satellites calling here you come again, Tropical Storm Dolly
Tropical Storm Dolly visited Mexico six years ago, and NASA satellite data is calling 'Here you come again,' reminiscent of the famous country singer's hit song, as another storm named Dolly heads for a second landfall in Mexico.

Discharged patients return to the ER because 'better safe than sorry'
Patients who return to the emergency department within a few days of discharge do so principally because they are anxious about their symptoms and have lost trust in other parts of the health care system, according to the results of a study published online today in Annals of Emergency Medicine.

Prepped by tumor cells, lymphatic cells encourage breast cancer cells to spread
Breast cancer cells can lay the groundwork for their own spread throughout the body by coaxing cells within lymphatic vessels to send out tumor-welcoming signals, according to a new report by Johns Hopkins scientists.

Diabetes mellitus and mild cognitive impairment: Higher risk in middle age?
In a large population-based study of randomly selected participants in Germany, researchers found that mild cognitive impairment occurred twice more often in individuals diagnosed with diabetes mellitus type 2. Interestingly, this strong association was only observed in middle-aged participants (50-65 years), whereas in older participants (66-80 years) the association vanished. This study is published in the Journal of Alzheimer's Disease.

Experiences make you happier than possessions -- Before and after
To get the most enjoyment out of our dollar, science tells us to focus our discretionary spending on experiences such as travel over material goods. A new Cornell University study shows that the enjoyment we derive from experiential purchases may begin even before we buy.

Residency training predicts physicians' ability to practice conservatively
Doctors trained in locations with less intensive (and expensive) practice patterns appear to consistently be better at making clinical decisions that spare patients unnecessary and excessive medical care, says a new study in JAMA Internal Medicine.

Study links sex hormone levels in the blood to risk of sudden cardiac arrest
Measuring the levels of sex hormones in patients' blood may identify patients likely to suffer a sudden cardiac arrest, a heart rhythm disorder that is fatal in 95 percent of patients.

Enzyme controlling metastasis of breast cancer identified
Researchers at the University of California, San Diego School of Medicine have identified an enzyme that controls the spread of breast cancer. The findings, reported in the current issue of PNAS, offer hope for the leading cause of breast cancer mortality worldwide. An estimated 40,000 women in America will die of breast cancer in 2014, according to the American Cancer Society.

Cool calculations for cold atoms
The first full theory that accounts for interactions at nano-kelivin temperatures -- in those situations where 3-atom states can form even while all 2-atom states are unstable.
