Toronto - Aristotle said, "Love is composed of a single soul inhabiting two bodies." Poetic as it is, thinking that you and your partner were made in heaven for each other can hurt your relationship, says a new study.

Bottom Line: Men and women who have served in the military have a higher prevalence of adverse childhood events (ACEs), suggesting that enlistment may be a way to escape adversity for some.

Authors: John R. Blosnich, Ph.D., M.P.H., of the Veterans Affairs Pittsburgh Healthcare System, and colleagues.

Background: The prevalence of ACEs among U.S. military members and veterans is largely unknown. ACEs can result in severe adult health consequences such as posttraumatic stress disorder, substance use and attempted suicide.

TORONTO, July 23, 2014 – Migratory songbirds are disappearing, and though conservationists are examining several possible reasons such as climate change, loss of habitat, acid rain and light pollution, a key piece of the puzzle has remained missing: where do these birds go once they leave their breeding sites, and what threats may they be encountering along the way?

Roughly 780 million people around the world have no access to clean drinking water. According to the World Health Organization (WHO), 3.4 million people die from water-related diseases every year. ETH student Jeremy Nussbaumer set himself the goal of making a contribution to solving this problem. Working with researchers from a group led by Wendelin Stark, head of the Functional Materials Laboratory, the 23-year-old spent a year researching a membrane filter and developing a prototype.

Washington, DC -- The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous release of carbon is balanced by carbon coming into the soil system from falling leaves and other plant matter, as well as by the underground activities of plant roots.

Geographers at the University of Southampton have found a link between increasing average temperatures in India and a reduction in wheat production.

Researchers Dr John Duncan, Dr Jadu Dash and Professor Pete Atkinson have shown that recent warmer temperatures in the country's major wheat belt are having a negative effect on crop yield. More specifically, they found a rise in nighttime temperatures is having the most impact.

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Vienna University of Technology and the Maria Curie-Skłodowska University Lublin have succeeded in embedding nearly perfect semiconductor crystals into a silicon nanowire. With this new method of producing hybrid nanowires, very fast and multi-functional processing units can be accommodated on a single chip in the future. The research results will be published in the journal Nano Research.

Ensemble forecasting is a key part of weather forecasting today. Computers typically run multiple simulations, called ensembles, using slightly different initial conditions or assumptions, and then analyze them together to try to improve forecasts. Now, using Japan's flagship 10-petaFLOPS K computer, researchers from the RIKEN Advanced Institute for Computational Science (AICS) have succeeded in running 10,240 parallel simulations of global weather, the largest number ever performed, using data assimilation to reduce the range of uncertainties.

A research team from the National Institute of Standards and Technology (NIST), working with the Cleveland Clinic, has demonstrated a dramatically improved technique for analyzing biological cells and tissues based on characteristic molecular vibration "signatures." The new NIST technique is an advanced form of the widely used spontaneous Raman spectroscopy, but one that delivers signals that are 10,000 times stronger than obtained from spontaneous Raman scattering, and 100 times stronger than obtained from comparable "coherent Raman" instruments, and uses a much larger portion of the vibra

Heading into the war room to fire up the troops? Declaring war on the competition to boost sales? Well, CEO, you might want to tamp down them's fightin' words—you could be shooting yourself in the foot.

A new Brigham Young University business study finds that bosses who try to motivate their employees with violent rhetoric—think of Steve Jobs declaring "thermonuclear war" on Samsung—end up motivating rival employees to play dirty.

To support the fair sale of gaseous hydrogen as a vehicle fuel, researchers at the National Institute of Standards and Technology (NIST) have developed a prototype field test standard to test the accuracy of hydrogen fuel dispensers. Once the standard is field tested, it will serve as a model for constructing similar devices for state weights and measures inspectors to use.

The challenges faced by researchers in modifying properties of nanomaterials for application in devices may be addressed by a simple technique, thanks to recent innovative studies conducted by scientists from the National University of Singapore (NUS).

WASHINGTON, July 22, 2014—Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.

Imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That's what Howard Milchberg, professor of physics and electrical and computer engineering at the University of Maryland, wants to do.
