A web-based study of 994 men and women with chronic migraine found that the condition significantly impacts family relationships and activities, including cancelled vacation plans and reduced quality time with partners and children. Feelings of guilt, anger and annoyance toward family members due to headache, and avoidance of sexual intimacy due to headache also were reported. Chronic migraine is generally defined as migraine with headaches occurring 15 or more days per month.

A working group evaluating sexual orientation-related disorders listed in the International Classification of Diseases (ICD), a publication of the World Health Organization (WHO), has recommended the disorders be deleted, a move that will make getting health care easier for gays and others who may have gender atypicality.

The WHO is the world body charged with deciding what is a disease and more than 170 countries, including the United States, follow their recommendations. The organization is currently revising the 10th edition of the ICD for release of the 11th edition in 2017.

In the coming decades, we will likely commute to work and explore the countryside in autonomous, or driverless, cars capable of communicating with the roads they are traveling on. A convergence of technological innovations in embedded sensors, computer vision, artificial intelligence, control and automation, and computer processing power is making this feat a reality.

More than 50 percent of consumers are interested in products with reduced levels of salt and sugar, and yet new products in the United States are more likely to tout low- or no-fat attributes, according to a June 23 panel discussion at the 2014 Institute of Food Technologists (IFT) Annual Meeting & Food Expo® in New Orleans.

In recent research, just 25 percent of consumers claimed to be dieting, yet more than 70 percent said they want to lose weight.

GAINESVILLE, Fla. --- University of Florida researchers have found evidence that an influenza A virus can jump from horses to camels – and humans could be next.

ANN ARBOR—In work that unmasks some of the magic behind memristors and "resistive random access memory," or RRAM—cutting-edge computer components that combine logic and memory functions—researchers have shown that the metal particles in memristors don't stay put as previously thought.

The findings have broad implications for the semiconductor industry and beyond. They show, for the first time, exactly how some memristors remember.

Diseases of the adrenal gland have long been difficult to diagnose. But now, researchers have found an affordable and easy way to diagnose and monitor endocrine diseases of the adrenal gland by using saliva and a smartphone.

Researchers at Intermountain Medical Center in Murray, Utah, have developed new smartphone technology to help screen patients for a number of adrenal gland diseases, including Cushing's syndrome. The new tool also helps to identify adrenal insufficiency, monitor cortisol replacement and assess physiologic changes in adrenal function.

CAMBRIDGE, Mass-- There is a story about how the modern golf ball, with its dimpled surface, came to be: In the mid-1800s, it is said, new golf balls were smooth, but became dimpled over time as impacts left permanent dents. Smooth new balls were typically used for tournament play, but in one match, a player ran short, had to use an old, dented one, and realized that he could drive this dimpled ball much further than a smooth one.

CHICAGO, IL—Researchers have developed a device that uses any smartphone to measure the cortisol concentration in saliva. The device was presented Tuesday, June 24, at ICE/ENDO 2014, the joint meeting of the International Society of Endocrinology and the Endocrine Society in Chicago.

Bottom Line: Cardiac resynchronization therapy plus defibrillator implantation (CRT-D) sometimes helps women with heart failure more than men, although women are less likely to receive CRT-D than men.

LAS CRUCES, NM – High-profile marketing campaigns for nuts such as pistachios and almonds have become familiar to consumers throughout the United States. Shining a spotlight on these products has increased public awareness and boosted sales. For example, domestic per-capita almond consumption has increased five-fold since 1976, thanks in part to savvy marketing efforts. In contrast, the pecan industry been successful in focusing their efforts on expanding pecan export markets, but pecan consumption in the U.S. has remained relatively flat over the past 35 years.

QUEBEC – In Canada, where outdoor growing seasons are limited, sales from greenhouse fruit and vegetable production operations still surpass $1.1 billion annually. Finding more efficient methods for providing lighting in greenhouse production is a key component to support these high levels of production and increase revenues. "Light irradiance is the limiting factor for increasing production in greenhouses, when all other factors (temperature, nutrient levels, and water availability) are adequately maintained," said the authors of a new study.

The D-Wave computer is currently the latest link of a long chain of computers designed for the solution of optimization problems. In what sense does it realize quantum computation? We describe the evolution of such computers and confront the different views concerning the quantum properties of the D-wave computer.

CAMBRIDGE, MA -- The more cores — or processing units — a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical Engineering and Computer Science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets, where each core has an associated router, and data travels between cores in packets of fixed size.

Press the start button, switch on the monitor, grab a cup of coffee and off you go. That is pretty much how most us experience booting up a computer. But with a quantum computer the situation is very different. So far, researchers have had to spend hours making dozens of adjustments and fine calibrations in order to set up a chip with just five quantum bits so that it can be used for experimental work. (One quantum bit or 'qubit' is the quantum physical equivalent of a single bit in a conventional computer).
