The increased use of engineered nanoparticles (ENMs) in commercial and industrial applications is raising concern over the environmental and health effects of nanoparticles released into the water supply. A study that analyzes the ability of typical water pretreatment methods to remove titanium dioxide, the most commonly used ENM, is published in Environmental Engineering Science.

Computers that function like the human brain could soon become a reality thanks to new research using optical fibres made of speciality glass.
The research, published in Advanced Optical Materials, has the potential to allow faster and smarter optical computers capable of learning and evolving.

Researchers at the Universities of Basel and Valencia have reported important advances in the development of next generation lighting technologies in the journal "Chemical Science".
Lighting technology is in a state of change. The old-fashioned light-bulb, which was more efficient at converting electricity into heat than light, is currently being replaced by fluorescent devices and it is expected that light emitting diodes (LEDs) will be the technology of choice in the mid-term future.
A new testosterone nasal gel raises men's low testosterone levels to normal, with few side effects, according to the results of a phase 3 clinical trial to be presented Saturday at the Endocrine Society's 97th annual meeting in San Diego.
Last May, the U.S. Food and Drug Administration approved the medication, now called Natesto, making it the only FDA-approved nasal testosterone replacement therapy, according to the manufacturer, Trimel Pharmaceuticals.
Obesity guidelines recommend an initial weight loss goal of 5 to 10% of start weight to improve health. A recent study found that patients who received liraglutide 3.0 mg, combined with fewer calories and more physical activity, were more than twice as likely to achieve at least that level of weight loss, compared to patients on placebo who made similar lifestyle changes.
An experimental drug causes loss of weight and fat in mice, a new study has found. The study results will be presented Friday at the Endocrine Society's 97th annual meeting in San Diego.
Known as GC-1, the drug reportedly speeds up metabolism, or burning off, of fat cells.
A trained scent dog accurately identified whether patients' urine samples had thyroid cancer or were benign (noncancerous) 88.2 percent of the time, according to a new study, to- be presented Friday at the Endocrine Society's 97th annual meeting in San Diego.
Nokia, Motorola, Sony-Ericsson and BlackBerry-maker Research in Motion were all victims of disruption. During the 1990s and 2000s, they led the cell phone during its period of takeoff into ubiquity. Then in the last five years, they all lost their leadership positions and are now on the verge of irrelevance. The common culprit was the 2007 launch of Apple’s iPhone.
Lithium-ion batteries are common in consumer electronics and one of the most popular types of rechargeable batteries for portable electronics, with a reasonable energy density, no memory effect and a slow loss of charge when not in use. But they are the oldest technology in that system, due to not having changed much since the World Wide Web first came into existence.
A letrozole pill once a week restored fertility in obese, infertile men and led to their partners giving birth to two full-term, healthy babies, according to a new study from Canada. The results will be presented Thursday at the Endocrine Society's 97th annual meeting in San Diego.
"To our knowledge, this is the first report of successful pregnancies with the use of letrozole at this low dose in men," said the study's lead investigator, Lena Salgado, MD, an endocrinology fellow at the Centre Hospitalier de l'Université de Montréal (CHUM).
Abaloparatide-SC, an injectable drug being studied for the treatment of postmenopausal osteoporosis, reduces the rate of new spinal fractures by a statistically significant 86 percent and as well as statistically significant reductions in the fracture rate at other parts of the body, a phase 3 clinical trial finds. Results of the ACTIVE fracture prevention trial will be described in a late-breaking oral presentation Thursday at the Endocrine Society's 97th annual meeting in San Diego.
A new paint makes robust self-cleaning surfaces and can be applied to clothes, paper, glass and steel and when combined with adhesives, maintains its self-cleaning properties after being wiped, scratched with a knife and scuffed with sandpaper.
Self-cleaning surfaces work by being extremely repellent to water but often stop working when they are damaged or exposed to oil. The new paint creates a more resilient surface that is resistant to everyday wear and tear, so could be used for a wide range of real-world applications from clothing and cars, say the researchers.
Methane is a potent greenhouse gas, though fortunately has a far shorter lifespan than the CO2 that is implicated in global warming. However, the prevalence of natural gas, cleaner energy which caused CO2 emissions to drop in America, have brought renewed concerns about its effects.
It is not just found in man-made wells, it is common in lakes and swamps, but natural-gas pipelines are the big concern. Understanding the sources of methane, and how the gas is formed, could give scientists a better understanding of its role in warming the planet.
The combinatorial, multi-gene GeneSight test has been found to better predict antidepressant treatment outcomes for patients with depression, and their use of health care resources, than any of the individual genes that comprise the test, according to a peer-reviewed analysis by investigators from the Mayo Clinic and Assurex Health, and published online by The Pharmacogenomics Journal .
