American College of Cardiology's 64th Annual Scientific Session PM tip sheet for March 14, 2015
Medical reports have linked energy drink consumption to adverse cardiac events such as changes in heart rhythm, heart attacks and even deaths in otherwise healthy people.

Heart CT scans show slight benefits over functional tests for heart disease
Patients with symptoms of heart disease have similar outcomes in terms of death and major cardiac conditions regardless of whether they undergo a functional stress test or a computed tomographic scan, but the scan may be better at ruling out the need for subsequent tests and procedures in patients who are free of heart disease, according to research presented at the American College of Cardiology's 64th Annual Scientific Session in San Diego.

New research finds oceanic microbes behave in a synchrony across ocean basins
Researchers from the University of Hawai'i - Manoa and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats -- the nutrient-rich waters off California and the nutrient-poor waters north of Hawai'i.

Paul Ehrlich and Ludwig Darmstaedter Prize for pioneer work in cancer immunotherapy
The prize-winners have made cancer immunotherapy a hot topic in medicine.

The link between hair disorders and susceptibility to dental caries
Today at the 93rd General Session and Exhibition of the International Association for Dental Research, researcher Olivier Duverger, National Institutes of Health-National Institute of Neurological Disorders and Stroke, Bethesda, Md., USA, will present a study titled 'Hair Keratins as Structural Organic Components of Mature Enamel: The Link Between Hair Disorders and Susceptibility to Dental Caries.'

Long-term ticagrelor cuts risk of future events after heart attack
Adding the antiplatelet drug ticagrelor to aspirin as long-term therapy after a heart attack significantly reduced the rate of subsequent death from cardiovascular causes, heart attack or stroke, with the benefit appearing to accrue for nearly three years, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session.

No real cost difference between types of tests that look for heart disease
A study comparing the overall economics of computed tomographic angiography with functional stress tests for evaluating patients with symptoms suggestive of possible blocked coronary arteries found no significant differences in costs over three years.

New clues from the dawn of the solar system
Sulfide chondrules, a new type of building blocks discovered in meteorites left over from the solar system's infancy, provide evidence for a previously unknown region in the protoplanetary disk that gave rise to the planets including Earth.

Scientists fly kites on Earth to study Mars
An unconventional research method allows UA planetary scientists to develop digital terrain models -- think Google Earth on steroids -- of geologic features on Earth, revealing that some of the things we see on Mars and other planets may not be what they seem. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
