    Most people who misuse opioids are first exposed to the drugs through prescriptions so improving prescribing is targeted as one way to help curb the nation's opioid abuse epidemic. A new study identified six types of risky opioid prescriptions and found that all were linked to a higher chance of death, including fatal opioid overdoses. The study found more than 6 percent of Massachusetts adults received a risky opioid prescription during a five-year period.

    Crystals are brittle and inelastic? A novel class of smart, bendable crystalline organic materials has challenged this view. Now, scientists have engineered a molecular soft cocrystalline structure that bends and twists reversibly and without disintegration when stimulated by high temperature, mechanical force, or under UV light. This multifunctional quality makes it a robust candidate for advanced molecular electronics and other new materials.

    Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated. New research shows the strongest evidence to date that this middle-of-the-road black hole exists, by serendipitously capturing one in action devouring an encountering star.

    It's been impossible to obtain images of an exoplanet, so dazzling is the light of its star. However, astronomers have the idea of detecting molecules that are present in the planet's atmosphere in order to make it visible, provided that these same molecules are absent from its star. Thanks to this innovative technique, the device is sensitive to the selected molecules, making the star invisible and allowing the astronomers to observe the planet.

    Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert infrared light into light at higher frequencies, are among the smallest continuously emitting lasers of their kind ever reported and can constantly and stably emit light for hours at a time, even when submerged in biological fluids such as blood serum.

    For women over 40, mammography is a necessary yet annoying procedure to endure every year or two. The technique, while valuable for reducing breast cancer deaths, is less than ideal because it exposes patients to X-ray radiation and requires their breasts to be painfully squished between plates. The plates flatten the breast so the X-rays can more easily pass through it and produce a clear image.

    One of the joys of shopping for many people is the opportunity to brag about their purchases to friends and others. But new research found one common situation in which people would rather not discuss what they just bought: when they're feeling like money is a little tight. In a series of studies, researchers found that consumers who felt financially constrained didn't want to talk about their purchases, large or small, with friends or strangers.

    It's natural for parents to do whatever they can to keep their children safe and healthy, but children need space to learn and grow on their own, without Mom or Dad hovering over them, according to new research. The study found that overcontrolling parenting can negatively affect a child's ability to manage his or her emotions and behavior.

A pilot study is the first to use a 3D virtual reality headset to test this tool as a distraction method in a pediatric setting. Children were given the choice of a roller coaster ride, helicopter ride or a hot-air balloon ride. Results show that anticipated versus actual pain and fear were reduced in 94.1 percent of the pediatric study subjects.

    Primates are fascinating. They are intelligent, live in complex societies and are a vital part of the ecosystem. Lemurs, lorises, galagos, tarsiers, monkeys and apes are our closest biological relatives and just like them, humans are also primates. However, while the human population spread to all corners of the earth, many of our closest relatives are under serious threat.

    A volcano in Ecuador with a deep cylindrical crater might be the largest musical instrument on Earth, producing unique sounds scientists could use to monitor its activity. New infrasound recordings of Cotopaxi volcano in central Ecuador show that after a sequence of eruptions in 2015, the volcano's crater changed shape. The deep narrow crater forced air to reverberate against the crater walls when the volcano rumbled.
