LIVERMORE, Calif. – Lawrence Livermore National Laboratory researchers have developed a new and more efficient approach to a challenging problem in additive manufacturing -- using selective laser melting, namely, the selection of appropriate process parameters that result in parts with desired properties.

Waiting until marriage to have babies is now "unusual" among less-educated adults close to 30 years old, Johns Hopkins University researchers found.

"Clearly the role of marriage in fertility and family formation is now modest in early adulthood and the lofty place that marriage once held among the markers of adulthood is in serious question," sociologist Andrew J. Cherlin said. "It is now unusual for non-college graduates who have children in their teens and 20s to have all of them within marriage."

Just as electronic circuits work with electrical charges, optical circuits process pulses of light, which gives them a distinct advantage in terms of speed. Optical technologies are therefore the object of intense research, aiming to develop novel optical devices that can control the flow of light at the nanometer scale. EPFL scientists have developed a new method that can optimally design a widely-used class of optical devices with unprecedented effectiveness.

TORONTO, June 16, 2014 — Do you work out for health benefits and feel you are exercising more than enough? You might be among the many Canadians who overrate how hard they work out or underestimate what moderate intensity exercise means, according to a recent study out of York University's Faculty of Health.

TORONTO, June 14, 2014—Canola is Canada's oil and new research from St. Michael's Hospital suggests it should also be one of the oils of choice for people with Type 2 diabetes.Dr. David Jenkins, head of the hospital's Clinical Nutrition and Risk Factor Modification Centre, compared people with Type 2 diabetes who ate either a low glycemic index diet that included bread made with canola oil, or a whole wheat diet known to reduce the risk of cardiovascular disease.

At 33, conflicts in the world last year increased by one compared to 2012. This is reported by peace researchers at Uppsala University's Conflict Data Program. The number has remained stable over the past decade. 2012 saw an increase in the number of battle-related deaths with the number of casualties in Syria completely overshadowing any other ongoing conflict. In 2012, two out of five people dying in battles, died in Syria.

Scientists are using a new method of 'caging' and cooling water molecules to study the change in orientation of the magnetic nuclei at the centre of each hydrogen atom - a process which transforms the molecule from one form of water to another.

By trapping water molecules in carbon spheres and cooling them, scientists at the universities of Southampton, Nottingham and Columbia University in New York, have been able to follow the change in form (or isomer) of the molecules.

The results of this work may one day help to enhance the diagnostic power of MRI scans.

By now, most people feel comfortable conducting financial transactions on the Web. The cryptographic schemes that protect online banking and credit card purchases have proven their reliability over decades.

As more of our data moves online, a more pressing concern may be its inadvertent misuse by people authorized to access it. Every month seems to bring another story of private information accidentally leaked by governmental agencies or vendors of digital products or services.

A new study of pollution records indicates that the Western Amazon, an area of unparalleled biological and cultural diversity, may have been contaminated by widespread oil pollution over a 30-year period. This work will be presented at the Goldschmidt conference in Sacramento, California

Years after the 2010 Deepwater Horizon Oil spill, oil continues to wash ashore as oil-soaked "sand patties," persists in salt marshes abutting the Gulf of Mexico, and questions remain about how much oil has been deposited on the seafloor. Scientists from Woods Hole Oceanographic Institution and Bigelow Laboratory for Ocean Sciences have developed a unique way to fingerprint oil, even after most of it has degraded, and to assess how it changes over time.

In today's Information Age, it's easy get overwhelmed by online content. On YouTube alone, over 100 hours worth of video is uploaded every minute. Showcasing the most interesting content allows providers to convey a certain level of quality to its audiences and encourages users to stay on the website, consuming content and winning advertising dollars for its provider. However, this influx of information makes it difficult for both content providers and users to determine what is interesting and worth consuming.

The UK has failed to match the gains made in reducing deaths among children and young adults by 17 other high-income countries in the European Union*, Australia, Canada, and Norway (EU15+) in the 38 years since 1970.

Alexandria, Va. — In 2006, a fossil collector and his crew discovered a rare fossil on private land in Montana's Hell Creek Formation: the bones of two fully articulated dinosaurs that appeared to have died together, locked in battle. The fossil duo — a small, pony-sized carnivorous tyrannosaurid and a slightly larger herbivorous ceratopsian, both now preserved in plaster — became known as the "Montana Dueling Dinosaurs." Last November, the fossils were put on the block at Bonhams auction house in New York City — but they did not sell.

An advance has been achieved towards next generation ultrasonic imaging with potentially 1,000 times higher resolution than today's medical ultrasounds. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated a technique for producing, detecting and controlling ultrahigh frequency sound waves at the nanometer scale.
