Monitoring men with very low- and low-risk prostate cancers using watchful waiting or active surveillance, called expectant management, is a useful approach for a large number of men with localized tumors and could spare them the debilitating side effects of aggressive treatments that are too often unnecessarily used in this patient population, a UCLA review of common practices in prostate cancer has found.
Using human tumor samples and mouse models, researchers at University of California, San Diego School of Medicine and Moores Cancer Center discovered that cancer stem cell properties are determined by epigenetic changes — chemical modifications cells use to control which genes are turned on or off.
Imagine a fleet of driverless taxis roaming your city, ready to pick you up and take you to your destination at a moment’s notice. While this may seem fantastical, it may be only a matter of time before it becomes reality. And according to a new study from Lawrence Berkeley National Laboratory, such a system would both be cost-effective and greatly reduce per-mile emissions of greenhouse gases.
Studying brain scans and cerebrospinal fluid of healthy adults, scientists have shown that changes in key biomarkers of Alzheimer's disease during midlife may help identify those who will develop dementia years later, according to new research.

For hikers, football players, endurance athletes, and a growing range of elite and recreational exercisers, the best approach to preventing potentially serious reductions in blood sodium level is to drink when thirsty, according to an updated consensus statement on exercise-associated hyponatremia (EAH). The recommendations appear in the June issue of the Clinical Journal of Sport Medicine, published by Wolters Kluwer.
University of Southampton scientists have discovered a link between coronary heart disease and osteoporosis, suggesting both conditions could have similar causes.
A new map of emergency stroke care in America shows just how much of a patchwork system we still have for delivering the most effective stroke treatment. And thousands of people a year may end up unnecessarily disabled as a result.
The Department of Energy’s Argonne National Laboratory this week released a study that shows gasoline and diesel refined from Canadian oil sands has a higher carbon impact than fuels derived from conventional domestic crude sources.
The acidity of urine — as well as the presence of small molecules related to diet — may influence how well bacteria can grow in the urinary tract, a new study shows. The research, at Washington University School of Medicine in St. Louis, may have implications for treating urinary tract infections, which are among the most common bacterial infections worldwide.
A new study suggests that errors on memory and thinking tests may signal Alzheimer’s up to 18 years before the disease can be diagnosed. The research is published in the June 24, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Smokeless tobacco and, more recently, e-cigarettes have been promoted as a harm reduction strategy for smokers who are “unable or unwilling to quit.” The strategy, embraced by both industry and some public health advocates, is based on the assumption that as smoking declines overall, only those who cannot quit will remain. A new study by researchers at UC San Francisco has found just the opposite.

A giant cloud escaping from a warm, Neptune-mass exoplanet is reported in this week’s Nature. Depicted in an image by Mark Garlick and issued by the University of Warwick, it has been suggested that low-mass exoplanets orbiting close to their parent stars could have had some fraction of their atmospheres ‘burnt off’ by extreme irradiation from the star, but confident measures of such losses have been lacking until now.
This phenomenon generates like a tail or a head of hair giving it the appearance of a giant comet. Already observed in some very large and very hot exoplanets, this phenomenon is viewed for the first time with such a magnitude. The cloud might explain the formation of some hot and rocky super-Earths. It would also be an indicator for detecting extrasolar oceans. Finally, it would be used to envisage the future of our atmosphere. These results are published in the latest edition of the journal Nature.
Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dispersing from a warm, Neptune-sized planet orbiting a nearby star. The enormous comet-like tail of the planet is about 50 times the size of the parent star. The findings will be published in the June 25 issue of the journal Nature.
A protein encoded by the gene glypican-1 (GPC1) present on cancer exosomes may be used as part of a potential non-invasive diagnostic and screening tool to detect early pancreatic cancer, potentially at a stage amenable to surgical treatment, according to a study at The University of Texas MD Anderson Cancer Center.
In late 2013, when the neutron star at the heart of one of our galaxy’s oddest supernovae gave off a massive burst of X-rays, the resulting echoes — created when the X-rays bounced off clouds of dust in interstellar space — yielded a surprising new measuring stick for astronomers.
A rigorous analysis of more than 20,000 medical records concludes that erectile dysfunction drugs, such as Viagra, are not a cause of melanoma, an often deadly form of skin cancer, despite the higher risk for the disease among users of these drugs.
Heart attack patients age 65 and older who have reduced heart function might still benefit from implanted defibrillators, according to a Duke Medicine study published in the Journal of the American Medical Association. But fewer than 1 in 10 eligible patients actually get a defibrillator within a year of their heart attacks, the study found.
The costs associated with cancer drug prices have risen dramatically over the past fifteen years, which is of concern to many top oncologists. In a new analysis, researchers at The University of Texas MD Anderson Cancer Center concluded the majority of existing treatments for hematologic, or blood, cancers are currently priced too high to be considered cost-effective in the United States.
Obesity and excess weight, and their negative impact on health, have become a significant focus for physicians and other health-care experts in recent years. But new research at Washington University School of Medicine in St. Louis shows that an escalation in the number of those considered obese or overweight in the United States continues, signaling an ongoing upward swing in chronic health conditions as well.
